The full anatomy of UK home-buying costs in 2026

A typical UK home purchase has the following cost lines: deposit, SDLT, conveyancing legal fees and disbursements, mortgage product/arrangement fee, mortgage broker fee (if any), basic valuation, full survey, local authority searches, water/drainage searches, environmental searches, Land Registry fee, ID/AML checks, telegraphic transfer, removals, post-completion utilities setup, and any leasehold-specific charges (notice fees, deed of covenant).

On a £350,000 owner-occupier purchase the typical breakdown is: £35,000 deposit (10%), £5,000 SDLT, £1,800 legal, £550 survey, £999 arrangement fee, £400 searches/Land Registry/disbursements, £500 removals — totalling £44,249 cash on completion week.

Hidden costs first-time buyers miss

Several costs surprise first-time buyers: the lender arrangement fee (£0–£1,995, often £999), the broker fee where used (£0–£495), telegraphic transfer (£20–£50 each direction), Land Registry online fees (£135–£330 by price band), AML checks (£20–£50 per person), Stamp Duty fee charged by some conveyancers (£40–£75), and the first month's mortgage payment due 4–6 weeks after completion.

Leasehold flats add several more: notice of transfer fee to the freeholder (£60–£200), notice of mortgage (£60–£200), deed of covenant (£60–£200), management company information pack (£200–£400), and apportioned ground rent and service charge at completion.

£200,000 FTB freehold flat

£20,000 deposit + £0 SDLT (under £425k FTB threshold) + £1,400 legal + £400 survey + £499 arrangement + £350 misc + £400 removals = £23,049 total cash.

£500,000 owner-occupier upgrade

£100,000 deposit + £12,500 SDLT + £2,400 legal + £700 survey + £1,500 arrangement + £450 misc + £700 removals = £118,250 total cash.

£400,000 BTL with corporate solicitor

£100,000 deposit (75% LTV BTL) + £27,500 SDLT (incl 5% HRAD) + £2,800 legal + £600 survey + £1,995 arrangement + £450 misc = £133,345. No moving cost as not occupied.

Common mistakes to avoid

• Forgetting Land Registry fees scale with price — £135 at £200k, £450 at £1m+ for online registration.
• Not budgeting first month's mortgage payment due before next salary.
• Underestimating leasehold completion charges — they can add £600+ to a flat purchase.
• Choosing the cheapest legal quote without checking complaint history — slow conveyancing can cost £100s in chain delays.
• Skipping the survey on older property to save £550 — has cost buyers £20,000+ in undiscovered defects.

When to use this calculator

After offer accepted to plan cash flow. Re-run after surveys for any renegotiation. Final check the week before completion to confirm completion-day cash transfers.

How this differs in Scotland, Wales and Northern Ireland

Scottish purchases use LBTT (lower for most prices) and Registers of Scotland fees (similar to Land Registry). Welsh purchases use LTT and Land Registry of Wales. Northern Ireland uses SDLT and a separate Land Registry. Conveyancing fees in Scotland are typically £900–£1,400 (lower than England) but London leasehold can exceed £3,000.

When this calculator is and isn't the right tool

The Property Purchase Cost Calculator UK 2025/26 above is built for the most common UK 2025/26 scenarios in this tax area. It will be the right tool when your situation maps cleanly onto the inputs — single property or simple aggregation, standard HMRC rates and bands, and individual taxpayer (rather than complex trust or partnership structures). It is informational and does not replace tailored advice from a chartered tax adviser, especially for transactions above £500,000, cross-border situations, or where reliefs interact with each other. For year-end filings, always reconcile with HMRC's own free calculators on gov.uk before pressing submit on Self Assessment.
