First-Time Buyer Mortgages UK 2026: From Saving a Deposit to Picking Up the Keys

The minimum deposit for most first-time buyer mortgages is 5% of the property price — £12,500 on a £250,000 home. But the size of your deposit directly affects the interest rate you'll be offered, because lenders price mortgages by loan-to-value (LTV) ratio.

At 95% LTV (5% deposit), expect to pay significantly higher rates than at 90% LTV (10% deposit) or 85% LTV (15% deposit). The sweet spot for most first-time buyers is a 10–15% deposit: it unlocks materially better rates without requiring years of additional saving. At 75% LTV (25% deposit), you'll access the very best deals, but saving £62,500 on a £250,000 property is unrealistic for most.

A Lifetime <a href="/posts/isa-season-last-chance-to-use-your-20000-isa-allowance-before-5-april-2026">ISA</a> (LISA) lets you save up to £4,000 per year and receive a 25% government bonus (up to £1,000 annually) — the most tax-efficient route for first-time buyers aged 18–39 purchasing a property under £450,000. See GOV.UK for current LISA rules.

The Bank of Mum and Dad remains the UK's biggest informal 'lender' — gifted deposits are accepted by most lenders provided the donor signs a declaration confirming it's a gift, not a loan. Some lenders also offer guarantor mortgages or family deposit schemes, where parents put savings into a linked account as security, enabling 100% LTV borrowing without a traditional deposit (though the parents' money is typically locked away for three to five years).

For a practical checklist of everything you need before applying, see our first-time buyer mortgage checklist.

The mortgage type you choose determines how your interest rate — and therefore your monthly payments — will change over time. For a detailed breakdown, see our complete mortgage rates guide.

Fixed-rate mortgages lock your rate for a set period, typically two or five years. With the base rate at 3.75%, two-year fixed rates for first-time buyers currently sit between 3.8% and 4.5% depending on LTV and lender. Five-year fixes are priced slightly higher at 3.9% to 4.6%. The key advantage is certainty: your monthly payment won't change regardless of what happens to interest rates.

Tracker mortgages follow the Bank of England base rate plus a fixed margin. A typical tracker might be base rate + 0.75%, giving a current pay rate of 4.50%. If the base rate falls to 3.50% as many economists expect by late 2026, your rate drops to 4.25% automatically. The risk is that rates could rise, pushing payments up. Our fixed vs tracker analysis weighs the trade-offs in detail.

Standard variable rate (SVR) is what you move onto when your initial deal expires. SVRs currently average around 7.5% — dramatically more expensive than any fixed or tracker deal. This is why remortgaging before your deal ends matters so much.

For most first-time buyers in 2026, a two-year or five-year fixed rate offers the best balance of affordability and certainty. A two-year fix lets you remortgage sooner if rates fall further; a five-year fix gives longer stability at a small premium.

<a href="/posts/stamp-duty-calculator-how-much-sdlt-youll-pay-on-your-uk-property-purchase">Stamp Duty</a> Land Tax (SDLT) is a tax paid on property purchases in England and Northern Ireland. First-time buyers benefit from a specific relief that significantly reduces the bill.

Since 1 April 2025, the first-time buyer SDLT thresholds are:

• £0 to £300,000: No stamp duty
• £300,001 to £500,000: 5% on the portion above £300,000
• Above £500,000: No first-time buyer relief; standard rates apply

A first-time buyer purchasing at £300,000 or below pays zero stamp duty. At £400,000, the bill is £5,000 (5% on £100,000). At £500,000, it's £10,000.

The temporary stamp duty holiday that raised the nil-rate band to £425,000 ended on 31 March 2025. If you're buying above £300,000, you'll now pay more than buyers who completed before that date. For analysis of how this affects real buying costs, see our stamp duty threshold analysis.

Scotland has its own Land and Buildings Transaction Tax (LBTT) with a higher nil-rate threshold (£145,000) for all buyers. Wales has Land Transaction Tax (LTT). Neither currently offers specific first-time buyer relief.

Several government-backed schemes can help first-time buyers get on the ladder, though availability and terms vary.

Lifetime ISA (LISA): Open to 18–39 year olds, the LISA gives a 25% bonus on savings up to £4,000 per year (maximum £1,000 bonus annually). The property must cost £450,000 or less. Our LISA guide covers the full rules and withdrawal penalties.

Shared Ownership: Buy a share (typically 25–75%) of a property and pay rent on the rest to a housing association. You only need a mortgage and deposit on your share. You can 'staircase' (buy more shares) over time. Our shared ownership guide covers costs and whether it's right for you.

First Homes: A government scheme offering new-build homes to local first-time buyers at a 30–50% discount off market price. Income caps apply (£80,000 nationally, £90,000 in London). Availability is limited to specific developments.

Right to Buy: Council or housing association tenants in England may be able to buy their home at a discount. Maximum discounts are £102,400 outside London and £136,400 in London (2025/26 figures). Eligibility depends on tenancy length.

The Help to Buy equity loan scheme closed to new applications in October 2022 and all completions finished by March 2023. For current alternatives, see our Help to Buy alternatives guide.

The purchase price and deposit are just the start. First-time buyers should budget for several additional costs that add £3,000 to £10,000+ to the total bill.

Solicitor/conveyancing fees: £1,000 to £2,000 including searches and disbursements. Your solicitor handles the legal transfer of ownership, title searches, and exchange of contracts.

Survey costs: A basic mortgage valuation (often free with your mortgage deal) only confirms the property's value for the lender. A HomeBuyer Report (£400–£600) or full Building Survey (£600–£1,500) checks for structural issues, damp, subsidence and other problems. Skipping a proper survey is one of the most expensive false economies in property buying.

Mortgage arrangement fees: Many of the best fixed-rate deals charge a product fee of £500 to £1,500. You can add this to the mortgage (meaning you'll pay interest on it for 25 years) or pay it upfront. A lower rate with a £1,499 fee may cost more over two years than a slightly higher fee-free rate — always compare the total cost.

Mortgage broker fees: Some charge £300 to £500 while others are paid by the lender. Whole-of-market brokers, who must be FCA-authorised, can access deals not available directly from lenders.

Moving costs and ongoing: Removal companies typically charge £400 to £1,500. Budget for furniture, appliances, and immediate repairs. Buildings insurance is required from exchange of contracts — expect £150 to £400 per year.

As a rule of thumb, budget an additional 3–5% of the property price for buying costs on top of your deposit and stamp duty. On a £250,000 property, that's roughly £7,500 to £12,500 extra.
