The 2026 first-time buyer's guide: deposits, mortgages, surveys & stamp duty

Buying your first home in the UK in 2026 is harder than it was for previous generations — but it is far from impossible. The average first-time buyer is now 34 years old, putting down a deposit of around £62,500 on a £253,000 property, according to Halifax's First-Time Buyer Review 2025. This guide walks through every stage in plain English, with the numbers you actually need.

Step 1 — Work out what you can really afford

Most UK lenders cap borrowing at 4.5× gross annual income; some go to 5.5× for higher earners or specific schemes. So a couple earning £35,000 each (£70,000 joint) could typically borrow £315,000. Combined with a 10% deposit (£35,000), that's a maximum purchase price of around £350,000 — before stress tests reduce it further.

The Financial Conduct Authority requires lenders to stress-test your income against a rate roughly 1% above their standard variable rate, so what you can borrow today is usually less than the headline 4.5× figure.

Step 2 — Save the right deposit (and the extras)

A 5% deposit is the floor; 10–15% is the sweet spot for materially better mortgage rates. UK Finance reported the average first-time buyer deposit in 2025 was 25% of the purchase price — largely because high earners and gifted deposits skew the average.

Budget for the extras most buyers underestimate:

• Stamp duty (see below) — from £0 up to thousands.
• Solicitor / conveyancing fees: typically £1,200–£2,000 including disbursements.
• Survey: £400 (Level 2) to £1,000+ (Level 3).
• Mortgage arrangement fee: £0–£1,500.
• Removals: £500–£1,500 depending on distance and volume.
• Buildings insurance from completion day.

Step 3 — Understand 2026 stamp duty for first-time buyers

From 1 April 2025, the first-time buyer relief threshold reverted to £300,000 (down from £425,000 during the temporary uplift). For purchases in England and Northern Ireland in 2026:

• Up to £300,000: 0% if you are a first-time buyer and the property is your only home (and ≤ £500,000 purchase price).
• £300,001 to £500,000: 5% on the portion above £300,000.
• Over £500,000: standard rates apply with no first-time buyer relief.

Wales uses Land Transaction Tax (LTT) — first-time buyers do not currently get a separate exemption; LTT starts at 0% up to £225,000. Always check GOV.UK or the Welsh Revenue Authority for live thresholds before exchanging.

Step 4 — Get a Decision in Principle before viewing

A DIP (sometimes called an Agreement in Principle) is a lender's soft-search statement that they would, in principle, lend you a given amount. Estate agents in 2026 routinely refuse offers from buyers who don't have one, because so many fall through. A whole-of-market mortgage broker is usually worth their fee — they see deals high-street branches don't.

Step 5 — Use the schemes that genuinely help

• Lifetime ISA (LISA): government adds 25% on savings up to £4,000 a year (£1,000 free) toward a first home worth up to £450,000.
• Shared Ownership: buy 25–75% of a property, pay rent on the rest. Now available on more homes since the 2024 reforms increased the minimum staircasing share to 5%.
• Mortgage Guarantee Scheme: extended into 2026, allowing 95% LTV mortgages on homes up to £600,000.

Step 6 — View properly

View at least twice, ideally at different times of day. A road quiet at 11am can be a school-run nightmare at 3pm. Check:

• Mobile signal in every room (a 2024 Which? survey ranked it the #1 missed factor by buyers).
• Water pressure on the top-floor shower.
• Loft hatch, meter cupboard and any rear access.
• Damp patches around windows, in corners and behind furniture.
• EPC rating — homes rated D or below will likely need investment within the next decade.

Step 7 — Always commission a survey

RICS reports nearly 1 in 5 buyers who skip a survey discover defects costing over £5,500 within the first year. A £500 survey is the cheapest insurance you'll ever buy. Level 2 (HomeBuyer Report) suits most modern homes; Level 3 (Building Survey) for anything pre-1930, listed, extended unusually, or showing signs of movement.

Step 8 — Conveyancing realistically takes 12–16 weeks

From offer accepted to keys, the UK average completion time in early 2026 was about 14 weeks (HM Land Registry data via Today's Conveyancer). Instruct your solicitor the day your offer is accepted, return paperwork the day it lands, and keep your mortgage broker copied in on everything.

Step 9 — Exchange, then complete

Exchange is the legally binding moment. After exchange, you (or your seller) can be sued for walking away. Buildings insurance must be live from exchange. Completion is usually 1–2 weeks later — though same-day exchange-and-complete is increasingly common in chain-free purchases.

Common first-time buyer mistakes to avoid

• Maxing out the budget — leave at least a 5% buffer for repairs in year one.
• Falling in love at the first viewing and skipping due diligence.
• Ignoring service charges and ground rent on leasehold flats — they can rise sharply.
• Forgetting that mortgage rates may shift before completion. Lock in early.
