House Buying Checklist UK: All 8 Stages, Costs and Timings for 2026

Buying a house in the UK takes around five to six months and breaks down into eight stages: get your finances ready, research areas and properties, view, make an offer, apply for your mortgage and book a survey, complete conveyancing and searches, exchange contracts, and complete. This checklist takes you through every stage with realistic timings, 2026 costs, and — the part almost every other guide skips — the free data checks that protect you from buying a problem.

The numbers say preparation matters more than ever. The average time from offer accepted to exchange of contracts hit 104 days in April 2026, up from 76 days in 2019, according to Connells Group. And 37% of agreed sales failed to complete in 2025, according to iamsold. Most of those collapses trace back to things a buyer could have checked before offering — which is exactly what the checks in Stage 2 are for.

The house buying checklist at a glance

Stages 5 and 6 run in parallel after your offer is accepted, which is why the whole journey typically lands at five to six months rather than nine. Work through the stages in order below — each one ends with the specific actions to tick off before moving on.

Stage 1: Get your finances ready (weeks 1–4)

You need a minimum deposit of 5% of the property price, though 10% or more unlocks noticeably cheaper mortgage rates, and lenders will typically lend 4.5–5.5 times your salary, according to MoneyHelper and the HomeOwners Alliance. Anchor that to real numbers: the UK average house price was £268,000 in the 12 months to March 2026, according to the ONS / HM Land Registry UK House Price Index — so a 5% deposit is £13,400 and a 10% deposit is £26,800. If you're a first-time buyer saving in a Lifetime ISA, the government adds a 25% bonus to contributions of up to £4,000 a year, per GOV.UK.

• Check your credit reports with all three agencies (Experian, Equifax, TransUnion) and dispute any errors — lenders will see what you see
• Register on the electoral roll at your current address; it's one of the simplest credit-score wins
• Gather three months of payslips and bank statements (or two to three years of accounts if self-employed)
• Get a mortgage agreement in principle — it's free, takes 24–72 hours, uses a soft credit search, and estate agents increasingly won't take your offer seriously without one
• Avoid new credit applications, large unexplained transfers or missed payments in the six months before applying

The true cost of buying a house in 2026

Stamp Duty Land Tax (SDLT) in England and Northern Ireland has used the same thresholds since 1 April 2025: standard buyers pay nothing up to £125,000, 2% on the portion to £250,000 and 5% above that, while first-time buyers pay nothing up to £300,000 and 5% on the portion between £300,000 and £500,000 — with no relief at all above £500,000, according to HMRC and MoneyHelper. Here's the full bill most checklists never itemise:

Worked example: a first-time buyer purchasing a £268,000 home with a 10% deposit needs roughly £29,000–£30,500 in cash — £26,800 deposit, £1,100–£2,200 conveyancing including disbursements, around £560 for a Level 2 survey, and £0 stamp duty. A home mover buying the same house adds about £3,400 in SDLT. Budget the cash before you start viewing, not after an offer is accepted.

Stage 2: Research areas and properties like a professional (weeks 2–6)

Every checklist tells you to "research the area". Almost none tells you how. The difference between guessing and knowing is a set of free, official government datasets that surveyors and conveyancers use — and that you can check yourself before you book a single viewing. These are also the checks HouseDossier pulls together automatically, but each one below can be run manually if you have the time.

Check sold prices, not asking prices

Asking prices are marketing; sold prices are evidence. HM Land Registry's Price Paid Data records the actual completion price of nearly every property sale in England and Wales, free at gov.uk/search-house-prices. With UK prices flat at 0.0% annual growth in the 12 months to March 2026 according to the ONS / HM Land Registry index, plenty of asking prices are still anchored to 2022–23 optimism — the data tells you which ones.

1. Search the exact property and its street on a sold house prices tool or the Land Registry site — note what it last sold for and when
2. Pull every sale of a similar type and size within about a quarter of a mile over the last 12–18 months; these are your comparables
3. Find the local ceiling — the highest price anyone has ever paid nearby. If the asking price is at or above it, you're being asked to set a street record (see what a ceiling price is and why it matters)
4. Compare the asking price against your comparables and ceiling — this becomes your negotiating evidence at Stage 4

Run the risk checks most buyers skip

Flood risk first, because the numbers are stark: 6.3 million properties in England are in areas at risk of flooding from rivers, the sea or surface water, rising to around 8 million — roughly 1 in 4 — by 2050 under climate projections, according to the Environment Agency's National Flood Risk Assessment (2025). Surface-water risk alone affects 4.6 million properties, a 43% increase on the previous assessment. Check any postcode free on the GOV.UK long-term flood risk service, or run a flood risk check that includes river, sea and surface-water layers in one view.

Then work down the rest of the risk list. Subsidence: the British Geological Survey maps clay shrink–swell ground that causes most UK subsidence claims — and a subsidence and mining check will also flag whether the property sits in a coalfield area, where a Coal Authority report is a mandatory part of conveyancing anyway. Crime: police.uk publishes street-level data monthly — compare a full 12 months of crime statistics by postcode rather than judging a single month. Planning: search the local council's planning portal (or a planning history lookup) for applications on the property and its neighbours — a rejected extension tells you about the house; an approved 40-home development behind the garden fence tells you about the next five years.

Schools, broadband and running costs

This is the liveability layer of the checklist. Check Ofsted ratings and catchment boundaries — popular catchments carry real price premiums, so verify the catchment before you pay for it. Test broadband and mobile coverage for the exact address on Ofcom's official checker — "fibre available in the area" on a listing is not a speed guarantee. Pull the property's EPC from the government EPC register: the A–G rating predicts your energy bills, certificates are valid for 10 years, and an EPC rating check will also show what the assessor recommended fixing. Finally, confirm the council tax band with the VOA — the band, not whatever the seller paid last year.

Stage 3: Viewings — the 20-point property checklist (weeks 4–10)

View any serious contender two or three times, at different times of day and at least once in the rain — gutters, damp and traffic noise all behave differently on a wet Tuesday at 8.30am than on a sunny Saturday viewing slot. Take this list with you:

• Damp and mould — check ceilings, around windows and behind furniture; trust your nose
• Cracks in walls — diagonal cracks above windows and doors are a classic subsidence flag
• Roof condition — missing or slipped tiles, sagging ridge lines, heavy moss
• Gutters, fascias and drainage — staining and overflow marks on walls
• Brickwork and pointing — crumbling mortar means maintenance bills
• Window frames — press them; rot, or condensation between double-glazing panes (failed units)
• Garden orientation — south-facing carries a premium; check it with a compass app, not the agent
• Boundaries — condition of fences and walls, and who owns which
• Boiler age and service history — ask to see the paperwork; replacements run to four figures
• Water pressure — run the taps upstairs and flush the toilet
• Fuse box — a modern consumer unit, or an antique fuse board hinting at old wiring?
• Sockets per room — rewiring is disruptive and expensive
• Fresh paint or new plaster in one isolated spot — ask what it's covering
• Storage — measure it, don't eyeball it
• Mobile signal — check your phone in every room
• Noise — traffic, neighbours, flight paths; listen with windows open
• Parking — what's actually allocated or permitted, not what's implied
• EPC rating on the listing versus the register — and the recommended improvements
• Council tax band — confirm it, and the current charge for that band
• Leasehold only: lease length, ground rent and service charges (see below)

While you're there, work the agent: how long has it been on the market, why is the seller moving, is there a chain, have any offers been made, and exactly what's included in the sale? We've covered the full script in questions to ask when viewing a house — the answers shape your offer strategy in the next stage.

Stage 4: Making an offer that sticks (weeks 8–12)

The asking price is an invitation, not a valuation. Open with your Stage 2 evidence: "Three similar houses on this street sold for £X–£Y in the last year" is an offer the agent has to relay and the seller has to engage with, in a way "we were hoping for a bit less" never is. Your position matters as much as your number — a chain-free first-time buyer with an agreement in principle frequently beats a higher offer from a buyer stuck in a chain, because the seller is pricing certainty too.

Remember that in England and Wales nothing is legally binding until exchange of contracts — which is precisely why 37% of agreed sales failed to complete in 2025, according to iamsold, with leasehold sales (43%) collapsing more often than freehold (36%). Stage 6 covers how to keep yourself out of that statistic.

Stage 5: Mortgage application and survey (weeks 1–6 after acceptance)

Submit your full mortgage application as soon as the offer is accepted — it typically takes two to four weeks to receive the formal offer, according to the HomeOwners Alliance. The lender will value the property, but be clear about what that is: a mortgage valuation protects the lender's money, not yours. It is not a survey, and it may be done without anyone setting foot in the house. Book your own independent RICS survey in parallel:

Two outcomes need a plan. If the lender down-values the property, you can renegotiate the price, challenge the valuation with your sold-price comparables, or increase your deposit to cover the gap. And if the survey finds problems, treat the report as a renegotiation tool rather than a deal-breaker — get quotes for the work and ask for a price reduction to match. We've broken down how to read the findings in do I need a survey when buying a house?, and what a property survey report does and doesn't cover.

Stage 6: Conveyancing and searches (weeks 1–12 after acceptance)

Your conveyancing solicitor checks the title, raises enquiries with the seller's side, runs the official searches, handles anti-money-laundering checks and prepares contracts. Budget £400–£1,500 in fees plus up to around £700 in disbursements, with the whole conveyancing process averaging 12–16 weeks, according to the HomeOwners Alliance — and around 120 days from instruction to completion on average, per Carbon Law Partners. The searches are the slow part: the local authority search alone can take up to five weeks to come back, alongside environmental, drainage and water searches, plus a Coal Authority report where the property sits in a coalfield area. Notice something? Almost everything the searches eventually reveal — flood, mining, planning — you already checked for free in Stage 2, months earlier, before you were emotionally and financially committed.

How to avoid being part of the 37% that fall through

Fall-throughs hurt because they happen late: collapsed freehold sales took 85 days on average to die, and leasehold sales 115 days, according to iamsold's 2025 data — months of fees and momentum gone. The causes are mundane and mostly preventable: chains collapsing, surveys surfacing surprises, mortgage problems and slow paperwork.

• Do the data checks before offering, so nothing in the searches ambushes you at week 10
• Respond to every solicitor enquiry within 24–48 hours — slow replies are the silent sale-killer
• Chase your solicitor and broker weekly; polite persistence measurably shortens conveyancing
• Have mortgage paperwork (ID, payslips, statements) ready before you offer, not after
• Agree realistic target dates for exchange and completion early, and put them in the memorandum of sale
• If you're flexible, weight your shortlist towards chain-free properties — fewer moving parts, fewer failure modes

Stage 7: Exchange of contracts (1–2 weeks before completion)

Exchange is the legally binding moment. Your solicitor transfers the deposit (usually 10%), the completion date is fixed in the contract, and if you withdraw after this point you forfeit that deposit. Exchange to completion is typically one to two weeks — occasionally same-day, sometimes two to four weeks by agreement if either side needs time.

One detail that catches buyers out: from the moment contracts are exchanged, the property is your risk — so buildings insurance must be in place from exchange day, not from the day you get the keys. Arrange the policy in advance and set the start date to the exchange date.

Stage 8: Completion day and your first week (day 0–7)

On completion day your lender releases the mortgage funds, your solicitor transfers the full balance to the seller's solicitor, and once it lands you collect the keys from the estate agent — usually by early afternoon. Then the final tick-boxes:

• Your solicitor files the SDLT return and pays any tax due (the return must be filed within 14 days of completion) and registers you as owner at HM Land Registry
• Take meter readings the day you get the keys, and photograph them
• Find the stopcock, fuse box and gas shut-off before you need them in a hurry
• Change the locks — you have no idea how many keys are in circulation
• Register for council tax and set up utilities and broadband
• Redirect your mail and update your driving licence and the electoral roll

Buying in Scotland or Wales: what changes

In Scotland, the process front-loads differently: the seller must provide a Home Report (a survey, energy report and valuation) before marketing, offers go through your solicitor, and the exchange of "missives" makes the deal binding far earlier than in England — so do your due diligence before offering, not after. Stamp duty is replaced by Land and Buildings Transaction Tax (LBTT), with its own bands. In Wales, the process mirrors England but the tax is Land Transaction Tax (LTT), with different thresholds and — importantly — no first-time buyer relief. Budget accordingly if you're buying across either border.
