Second Home Mortgages
Residential mortgages for the cottage in Cornwall, the flat in Marylebone, the bolt-hole in Edinburgh. Mortgages from £250,000 plus.
A second home mortgage is a residential mortgage on a property you, your partner or your immediate family will use as a secondary home. A holiday cottage, a London pied-a-terre, a country bolt-hole, a flat for a child at university. It is not a buy-to-let. The property is not let to a tenant for income.
Fox Davidson arranges second home mortgages from £250,000+ in England, Scotland and Wales. Senior broker on the first call, with full market access across high street, building society, specialist residential and private bank routes. We model the SDLT surcharge and the combined affordability before you offer.
Second home mortgages in 2026
A second home mortgage is a residential mortgage on a property you, your partner or your immediate family will use as a secondary home. A holiday cottage in the Cotswolds, a London pied-a-terre, a country bolt-hole, a flat for a child at university, a downsizer your parents will live in that you co-fund. The property is not let to a tenant for income. That is the line between this product and a buy-to-let, and it is the line the SDLT surcharge sits on as well.
Fox Davidson arranges second home mortgages from £250,000+ on residential property across England, Scotland and Wales. We work with the full residential lender market: high street clearing banks, building society HNW desks, specialist residential lenders for complex income, and private banks for HNW the FCA high net worth rules clients buying second homes at £1m and above.
In the cases we arrange, three things matter on a second home application that do not matter as much on a first-time purchase. The 5% SDLT additional dwelling surcharge (raised from 3% in October 2024) lands on the full purchase price, not just the slice above the threshold. The lender stress-tests both mortgages, so the existing main residence payment stacks on the new one. And the right second home lender is rarely the lender that placed your main residence two or three years ago.
Common Fox Davidson second home scenarios
Second home mortgages cover a wider range of life events than the high street product set suggests. The six patterns below cover most of the cases we arrange in any given year. Each has its own lender shortlist and its own affordability conversation.
Holiday cottage
The Cotswolds stone cottage, the Cornwall fisherman's house, the Dorset coastal pile, the Lakes farmhouse. Family use through the school holidays, the occasional summer week with friends.
London pied-a-terre
The City family with a Surrey main residence keeping a Marylebone flat. Two nights a week in town, the occasional weekend, the once-a-month dinner that runs late.
Scottish bolt-hole
Edinburgh New Town flat, Highland croft, coastal Argyll cottage. LBTT and ADS apply rather than SDLT. We work with Scottish lenders directly.
Coastal holiday home
Salcombe, Padstow, Aldeburgh, North Norfolk, the Gower. Family use through the year. Not let out. Local building societies often lead on coastal lending.
University flat for a child
Parents purchasing a flat for a child to live in during studies. Bath, Bristol, Durham, Edinburgh, Exeter, Oxford, Cambridge. Sui generis HNW use case with specific lender criteria.
HNW the FCA high net worth rules private bank route
£1m+ second home purchase by an HNW borrower (income above £300,000 or net assets above £3m). Whole-of-wealth assessment, higher LTV available, larger loan sizes.
Second home vs holiday let vs second residential mortgage
The product distinction matters from the first call. Three close-but-different products serve different intentions, and choosing the wrong one is both a regulatory issue and an affordability one.
- Second home mortgage. A residential mortgage on a property used as a secondary home. No letting income relied on, no letting income permitted under the loan terms. Full residential affordability assessment based on your income. SDLT 5% additional dwelling surcharge applies. This is the page you are on.
- Holiday let mortgage. A specialist commercial-leaning product for property let to paying guests on short-term bookings. Income assessment uses an AST comparable rent at 145% ICR, a qualified letting agent projection, or actual trading history. Different lender pool, typically higher rates. FHL tax regime ended April 2025. See our holiday let mortgages page.
- Second residential mortgage. A rare product for borrowers who genuinely need two main residences (a working relocation that the family does not move with, a parent-care situation, an illness). Affordability assessed on income across both properties. Some lenders price as standard residential, others apply a small uplift.
If you plan to let the property out for even a few weeks a year, you have crossed the line into holiday let territory and the second home product no longer fits. We sometimes see clients drift between intentions during the buying process. The conversation we have early is which product you actually want, before the affordability work begins.
How second home affordability is assessed
The critical point on a second home application is that the lender assesses BOTH mortgages. The existing main residence mortgage payment, the new second home mortgage payment and all committed expenditure stack into one combined budget.
- Combined payment stress. The lender takes your existing main residence mortgage payment at its current rate, then stress-tests the new second home mortgage at the lender's stress rate (typically 6.5% to 7.0% pay rate on standard high street). Both are deducted from your affordability budget.
- Income multiples. Combined-loan multiples typically sit at 4.5x to 5.5x of gross income on standard high street, with 6x and above available via specialist lenders and private bank routes for HNW profiles. The multiple is applied to total borrowing across both properties, not just the new loan.
- HNW the FCA high net worth rules. HNW clients (income above £300,000 or net assets above £3m) sit outside the standard affordability stress framework. Private banks under the FCA high net worth definition run a whole-of-wealth assessment instead. Run the FCA HNW qualification check if you may qualify.
- Maximum LTV. Typically 75% to 80% on second home (slightly tighter than main residence). HNW private banks lend up to 85% to 90% LTV against £1m+ properties on strong covenant.
- Let-out rental income. If you plan to move into the new property and let the main residence out, the rental income from the main residence can be used to support combined affordability with a small number of specialist lenders. Most high street lenders will not accept this. Treated as a let-to-buy arrangement with separate paperwork.
What we find with second home cases is that the existing main residence mortgage is often the binding constraint, not the new loan. Where the existing mortgage is at a high LTV or sits on a high pay rate from a 2022 or 2023 fix, the combined stress test gets tight. In those cases we either wait until the existing mortgage rolls onto a lower fix, or we restructure around the main residence first.
Second home lenders and rates in 2026
The active second home mortgage lender list in 2026 is broader than most borrowers expect. The right lender depends on your income profile, the deposit, the property type, the region, and whether the case falls inside or outside HNW the FCA high net worth rules.
- High street clearing banks. Halifax, NatWest, Lloyds, Barclays, HSBC, Santander, Nationwide. Most treat a second home as a standard residential product with some criteria adjustments (slightly lower max LTV, combined affordability stress).
- Building societies (HNW desks for larger loans). Skipton, Coventry, Yorkshire, Leeds, Suffolk, Furness, Cumberland. Strong on coastal, rural and country second homes where manual underwrite matters.
- Specialist residential lenders. Saffron, Buckinghamshire, Clydesdale, Vida. Flexible on combined affordability and complex income. Useful where the high street stress test bites.
- Private banks for HNW the FCA high net worth rules clients. Coutts, Weatherbys, Investec, Barclays Private Bank, Arbuthnot Latham, Hampden & Co. Whole-of-wealth assessment, higher LTV bands, larger loan sizes. Typical AUM expectation in proportion to the loan size.
Indicative 5-year fixed rates for second home purchases in 2026:
- HNW private bank (the FCA high net worth rules, strong covenant, sub-60% LTV): from BoE base + 1.5% = 5.25%
- Prime high street second home (clean credit, 60-65% LTV): 4.85% to 5.50%
- Mainstream second home (65-75% LTV, standard income): 5.00% to 5.85%
- Specialist second home (complex income, 75-80% LTV): 5.65% to 6.50%
- Building society HNW manual underwrite (large loan, country property): 5.25% to 6.00%
Rates and lender criteria are subject to change. Figures correct at time of publication. Always speak to your broker for up-to-date rates and lending criteria on your specific case.
SDLT on second home purchases in 2026
The 5% additional dwelling surcharge (raised from 3% on 31 October 2024) is the single biggest cost most second home buyers underestimate. Three rules matter on every case.
- Who it applies to. The surcharge applies if you, or your married partner, already own ANY UK residential property at the point of completion. The test is at completion, not at exchange. Owning even a small share in another residential property triggers the surcharge.
- How it is calculated. The 5% surcharge is calculated on the FULL purchase price, not just the slice above the second-home threshold. On a £750,000 purchase, the surcharge is 5% of £750,000 = £37,500, added to the base SDLT of £25,000, totalling £62,500.
- The 3-year refund window. If you sell your previous main residence within 3 years of completing on the new one and the new property becomes your main residence, you can reclaim the 5% surcharge. The refund applies to genuine main-residence swaps where the new property replaces the old, not to second-home retention.
In Scotland, the equivalent surcharge is the Additional Dwelling Supplement (ADS) at 8%, on top of LBTT. In Wales, Land Transaction Tax (LTT) has a 5% higher-rate surcharge. The bands and thresholds differ across the three regimes. Run the figure on your specific case before you offer.
Bristol couple, Cotswolds cottage, £620,000 second home
A representative case from earlier this year, anonymised. Married couple in their mid-forties. Husband 46, senior management consultant, £110,000 base plus £30,000 bonus average. Wife 44, senior lecturer at a Bristol university, £70,000 base. Combined gross £180,000. Two children, 12 and 9, in state secondary. Existing committed expenditure including a small car finance and household bills, £36,000 per year.
Main residence: £950,000 four-bed Victorian in Clifton, Bristol. Existing mortgage £420,000 at 4.5% fixed until late 2027, current payment £2,200 per month, current LTV 44%. Owned by both spouses jointly.
Target purchase: £620,000 stone cottage in the Tetbury area of the Cotswolds. Family use through school holidays and the odd weekend through the year. Not let out. Deposit £155,000 (25%), borrowing £465,000 at 75% LTV on a 25-year capital-and-interest term.
SDLT calculation: base SDLT on £620,000 in 2026 standard residential = £20,000. Additional dwelling surcharge at 5% of £620,000 = £31,000. Total SDLT = £51,000. The couple add this to the deposit cash they need to find. We confirm the figure on the calculator before they offer.
Affordability: Halifax 5-year fixed at 5.15% on the new second home gives a monthly payment of £2,720. Combined housing cost across the two mortgages is £4,920 per month against gross monthly income of £15,000. Pre-tax housing cost ratio 33%. Halifax stresses the new loan at 7.5% pay rate. The case clears by a margin of about £140 per month, tight but workable. A specialist lender at a 6.0% pay rate stress would have been more comfortable but rate would have been 50 to 70 basis points higher across the term.
Sarah's note: this case worked at Halifax because the existing mortgage rolls onto a lower fix in 18 months and the bonus has a clean two-year history. On a similar profile with a higher-rate existing fix or a less stable bonus, we would have steered to a specialist lender on slightly higher rate, lower stress.
When a second home mortgage works and when it does not
The cases we place. Stable combined household income covering both mortgages at the lender's stress rate. A deposit that lands at or below 75% LTV on the second home. SDLT surcharge already costed in (not bolted onto an over-stretched budget). A clear use plan (family weekends, school holidays, a child at university for three years) that does not drift toward letting income.
The cases we steer away from. Borrowers expecting to let-out the cottage for a few weeks a year to defray running costs (that is holiday let territory and a different conversation). Borrowers whose existing main residence mortgage is at a high LTV already (the combined stress rarely clears). Borrowers in negative equity or with recent credit events on the main residence loan. Borrowers buying a second home as a workaround for an affordability problem on a main residence purchase.
In our experience the honest second home conversation is usually shorter than the holiday let conversation. The maths is cleaner because you are not modelling rental income or void periods. The conversation is mostly about whether the combined household budget supports two mortgages, and whether the SDLT surcharge fits into the cash plan.
One blunt point. The 5% SDLT surcharge is not negotiable. We sometimes see buyers try to structure around it (buying in a child's name, transferring the main residence before completion). Some of those structures work in specific circumstances. Most do not. We are not tax advisers but we will tell you, plainly, where a proposed structure is unlikely to deliver the SDLT saving the buyer is hoping for, and where you need a tax solicitor in the conversation.
How Fox Davidson arranges your second home mortgage
Second home cases live or die on the early conversation. The right lender shortlist, the right SDLT figure and the right combined affordability run all need to be settled before you instruct on the property.
Step 1: Case scoping (intent, SDLT, affordability)
We confirm the intended use of the property (family use only, not let), then run the SDLT figure on your specific price and region, then run combined affordability across both mortgages at the standard high street stress rate. The output of this call is whether the case fits inside high street criteria, or whether we should be looking at a specialist lender or a private bank route from the outset.
Step 2: Lender shortlist
We shortlist the three to five lenders with the best fit on your profile. Criteria: maximum borrowing they would offer on combined affordability, rate competitiveness on the second home product, treatment of any variable income (bonus, dividend, RSU), and underwriting flexibility on the specific case. For HNW the FCA high net worth rules cases we add the private bank route in parallel.
Step 3: Indicative terms and RICS valuation
We secure indicative terms from the chosen lender, including the indicative rate, fees and combined affordability ceiling. The RICS valuation is instructed on the property. The valuation result confirms maximum LTV against the actual lender's tolerance on the property type and region.
Step 4: Underwriting and conveyancing
We present the income evidence in the format the underwriting team expects, including pay slips, bonus letters, tax computations, and committed expenditure detail. The conveyancer handles the SDLT return, including the surcharge. We stay on the case through underwriting to formal mortgage offer.
Step 5: Completion
On completion the lender releases funds, the SDLT is paid through the conveyancer, and the second home becomes the secondary home. We stay in touch for the rate roll-off conversation 18 to 24 months ahead of fix expiry, and for any subsequent restructuring conversation on the main residence loan.

Frequently Asked Questions
What is a second home mortgage?
A second home mortgage is a residential mortgage on a property you, your partner or your immediate family will use as a secondary home rather than as a main residence. The property is not let to a tenant for income. Typical use cases include holiday cottages, London pied-a-terres, country bolt-holes, university flats for a child to live in, and HNW second residences. The lender assesses combined affordability across both the main residence mortgage and the new second home mortgage.
How much SDLT do I pay on a second home in 2026?
In England and Northern Ireland the 5% additional dwelling surcharge (raised from 3% on 31 October 2024) applies on top of standard residential SDLT, calculated on the full purchase price. On a £750,000 second home the surcharge alone is £37,500, on top of base SDLT of £25,000, totalling £62,500. In Scotland the Additional Dwelling Supplement is 8% on top of LBTT. In Wales the Land Transaction Tax higher-rate surcharge is 5%. Run the figure on the Fox Davidson stamp duty calculator before you offer.
Can I let out my second home occasionally and still call it a second home?
No. A second home mortgage prohibits letting the property to paying guests. Even a few weeks of short-term letting a year crosses into holiday let territory and breaches the loan terms. If you intend to let out the property for any meaningful portion of the year, you need a holiday let mortgage rather than a second home mortgage. The two products have different lender pools, different income assessment methods, and different rates. Speak to us at the start of the buying process so we apply for the right product first time.
Can I get a second home mortgage with my existing residential mortgage still in place?
Yes, this is the standard scenario. The lender will assess combined affordability across both mortgages at the lender's stress rate, plus your committed expenditure. If your income comfortably covers both stressed payments and your existing main residence sits at a manageable LTV, the case usually clears. Where the existing main residence mortgage is at a high LTV or on a high pay rate from a recent fix, the combined stress can become tight and we sometimes recommend waiting for the existing mortgage to roll onto a lower fix before applying for the second home loan.
What is the difference between a second home mortgage and a holiday let mortgage?
A second home mortgage is a residential product for property used personally by you and your family, with no letting income relied on or permitted. A holiday let mortgage is a specialist commercial-leaning product for property let to paying guests on short-term bookings, with income assessed against AST comparable rent at 145% ICR, qualified letting agent projections, or actual trading history. The lender pools are different, the rates differ, and the SDLT position is the same on both (5% additional dwelling surcharge applies to either if you already own a UK residential property).
What LTV can I get on a second home?
Most high street lenders cap second home LTV at 75% to 80%, slightly tighter than the maximum LTV on a main residence. Building society HNW desks and specialist residential lenders can go to 80% on strong cases. Private banks under the FCA high net worth definition can lend up to 85% to 90% LTV against £1m+ second homes for HNW borrowers with strong covenant. The realistic working assumption for most second home applications is 75% LTV. A larger deposit (lower LTV) unlocks better rates and more flexible affordability across all tiers.
Can I buy a second home for my child to live in at university?
Yes. Parent-purchased second homes for a child to occupy during studies are a recognised use case across the residential lender market. The mortgage is taken in the parent's name (not the child's), the parent funds it from their own income, and the child lives in the property without paying rent. The 5% SDLT surcharge still applies because the parent already owns a main residence. If the child intends to live in the property alone, no other occupants pay rent, and the parent has no letting intention, this fits cleanly as a second home rather than a buy-to-let. Some lenders treat this as a regulated family BTL instead. We will tell you which route fits.
Can I claim back the SDLT surcharge if my second home becomes my main residence?
Yes, in a specific scenario. If you sell your previous main residence within 3 years of completing on the new property AND the new property becomes your main residence, you can reclaim the 5% additional dwelling surcharge from HMRC. The refund mechanism applies to genuine main-residence swaps where the new property replaces the old, not to second-home retention. The 3-year window is measured from the completion date on the new property. Your conveyancer files the refund claim. This is one of the rare situations where the SDLT surcharge is recoverable.
Do private banks offer second home mortgages?
Yes. Private banks (Coutts, Weatherbys, Investec, Barclays Private Bank, Arbuthnot Latham, Hampden & Co) lend on second home purchases for HNW clients. The criteria are typically income above £300,000 or net assets above £3 million (the FCA high net worth definition high net worth definition,). Affordability is assessed against the whole-of-wealth position rather than against a formal income multiple. Private banks can lend at higher LTV bands (up to 85% to 90% on the right covenant) and at larger loan sizes. AUM expectations typically apply in proportion to the loan.
Can I get an interest-only second home mortgage?
Yes. Interest-only is available on second home mortgages from a smaller part of the residential lender market. Typical criteria: a credible repayment vehicle (cash savings, ISAs, investment portfolio, downsizing plan), a strong income profile, and lower maximum LTV (typically 60% to 65%) than the capital-and-interest equivalent. HNW the FCA high net worth rules clients have broader interest-only access through the private bank route, often paired with an investment-portfolio repayment vehicle. Part-and-part (a mix of interest-only and capital-and-interest) is available with several mainstream lenders.
How do high-street lenders assess affordability on a second home?
The lender takes your gross household income, deducts committed expenditure (existing mortgage payment, credit cards, car finance, school fees, childcare), then applies an income multiple to determine maximum borrowing. The existing main residence mortgage payment is assessed at its current contractual rate. The new second home mortgage is stress-tested at the lender's stress pay rate, typically 6.5% to 7.0% on standard high street. Both stressed payments deduct from the affordability budget. If the combined stressed payments fit within the budget at the applied income multiple, the case clears.
Can I get a second home mortgage as a non-UK resident?
Yes, on a narrower part of the market. The main lender route for non-UK residents buying a UK second home is private banks (Coutts, Weatherbys, Investec, Barclays Private Bank) and a small number of specialist international lenders. The SDLT picture is different too: a 2% non-resident surcharge applies on top of the standard SDLT and the 5% additional dwelling surcharge, taking the total surcharge to 7% for non-UK resident buyers of second homes. The combined effect on a £750,000 purchase is meaningful. We work alongside your tax adviser to model the all-in cost before you offer.
Why a specialist broker matters on second home mortgages
Most second home cases sit at the harder end of the residential lender's normal day. Combined affordability is tighter than a standard single-property purchase, the SDLT surcharge eats into the deposit cash, and the lender that placed your main residence two years ago is rarely the lender that fits the second home now.
What we find with second home cases is that the lender that wins is the one that reads the existing main residence mortgage correctly. A small change in how the existing payment is treated (current contractual rate versus stressed rate) can shift maximum new borrowing by £100,000 to £200,000. The criteria sit in the lender's underwriting policy, not on the rate sheet.
In the cases we arrange, we routinely run combined affordability across four or five lenders before instructing. The output spread is rarely a small one. On a recent £180,000 income couple buying a £620,000 cottage, the spread from the tightest lender to the most generous was about £180,000 of usable new borrowing. Same household, same week, same property. The lender selection delivered the result.
The cases we find easiest to place are the cleanest ones. Stable PAYE or salaried-and-bonus income, deposit at or below 75% LTV on the second home, existing main residence mortgage at a comfortable LTV. The cases we work hardest on are HNW the FCA high net worth rules second homes where the private bank conversation has to run in parallel with the AUM relationship, and cases where the existing main residence mortgage needs restructuring at the same time. We do both.
