The house buying process in England and Wales involves around ten distinct stages, takes between 12 weeks and eight months from offer to completion, and involves several professionals working in parallel — a mortgage lender, a conveyancer, a surveyor, and an estate agent. Understanding what happens at each stage, what you are responsible for, and where delays typically occur is the difference between a process that moves smoothly and one that drags for months.
This guide covers every step in the correct sequence, with realistic timeframes and the key decisions you need to make at each point.
Step 1 — Work Out What You Can Afford
Before viewing any properties, establish your realistic budget. This means two things: the maximum you can borrow and the full cost of buying, not just the deposit.
Mortgage affordability. Most lenders advance between 4 and 4.5 times your gross annual income. Some specialist lenders and first-time buyer schemes now offer up to 5.5 times for eligible applicants. A household income of £70,000 can typically borrow £280,000 to £315,000 on standard terms.
Total buying costs. The deposit is only part of it. Budget for:
- Stamp Duty Land Tax — from April 2025, first-time buyers pay no SDLT on properties up to £300,000, then 5% on the portion to £500,000. Non-first-time buyers pay SDLT from £125,001 upward, and a 5% surcharge applies to additional properties.
- Conveyancing fees — typically £1,500 to £3,000 for a standard purchase
- Survey — £300 to £1,500 depending on type
- Mortgage arrangement fee — £500 to £2,000 depending on the product
- Removal costs
Total transaction costs on a typical London purchase are often £20,000 to £40,000 on top of the deposit. Model the full number, not just the headline deposit figure.

Step 2 — Get a Mortgage in Principle
A Mortgage in Principle (MiP) — also called an Agreement in Principle or Decision in Principle — is a preliminary confirmation from a lender of how much they will lend you, subject to full affordability assessment and valuation.
Getting one takes 24 to 48 hours and typically involves a soft credit check that does not affect your credit score. You should have it in place before making any offers — estate agents will ask for it, and sellers and their agents take offers more seriously from buyers who can demonstrate mortgage availability.
Use a whole-of-market mortgage broker rather than going direct to your bank. Brokers access products from across the market, including deals not available direct, and can identify the lenders most likely to approve your application at the best rate. The cost difference between finding an optimal deal and defaulting to your existing bank can be tens of thousands of pounds over a mortgage term.
Step 3 — Search for a Property
Property searching takes most buyers between one and six months, though it varies enormously. In London’s fast-moving market, suitable properties can be listed and under offer within days, requiring buyers to be ready to move quickly.
Set up alerts on Rightmove, Zoopla, and OnTheMarket for properties matching your criteria. Register with local estate agents — many properties in sought-after areas are offered to registered buyers before appearing on portals.
At the viewing stage, look beyond staging and presentation. The checklist that matters at a viewing is structural and practical: roof, guttering, walls for damp, ceilings for water stains, boiler age and condition, window frames, bathroom sealant, loft condition. Bring a tape measure for rooms where size is a concern.
Step 4 — Make an Offer
Offers in England and Wales are made verbally through the estate agent and are not legally binding until contracts are exchanged. Either party can withdraw at any time before exchange — a system known as gazumping (seller accepts a higher offer from another buyer) and gazundering (buyer reduces their offer before exchange) both remain legal.
When making an offer, consider:
- The sold prices of comparable properties in the street over the past 12 months (available on Rightmove and Zoopla)
- How long the property has been on the market — extended marketing periods indicate overpricing or a problem
- Whether you are in a chain and whether being chain-free gives you negotiating leverage
Once an offer is accepted, the property is listed as Sold Subject to Contract (SSTC). Nothing is legally committed at this point.
Step 5 — Instruct a Conveyancer and Apply for Your Mortgage
These two steps happen simultaneously and should both begin immediately after offer acceptance.
Conveyancing is the legal process of transferring property ownership. Your conveyancer will conduct property searches — local authority, drainage and water, environmental, and others — review the contract pack from the seller’s solicitor, raise enquiries about the property, check the title, and report on any issues before you commit to exchange.
Searches alone can take between four and eight weeks depending on the local authority. Instructing your conveyancer the same day your offer is accepted rather than waiting a week or two can materially compress the overall timeline.
Mortgage application. Submit your full mortgage application promptly. Lenders require payslips, bank statements, proof of deposit source, and ID. The lender will instruct a mortgage valuation of the property, which confirms it is suitable security for the loan. This is not the same as a survey — it is a brief inspection for the lender’s benefit only.
Step 6 — Commission a Survey
A mortgage valuation is not a survey. It does not identify structural issues, defects, or maintenance problems that will affect the cost of owning the property.
The three survey types available are:
- RICS Level 1 (Condition Report) — basic condition overview for new or recently built properties in good condition. £300 to £500.
- RICS Level 2 (HomeBuyer Report) — the most commonly used survey for standard residential properties. Identifies significant issues and provides a market valuation. £500 to £1,000.
- RICS Level 3 (Building Survey) — the most thorough option, recommended for older properties, those with obvious defects, or unusual construction. £900 to £1,500.
For most London properties — which tend to be Victorian or Edwardian stock with decades of owner improvements — a Level 3 is usually the better investment. The cost of the survey is trivial compared to the cost of discovering a structural problem after completion.
If the survey reveals significant issues, you can use the findings to renegotiate the purchase price, request that remedial works are completed before exchange, or withdraw from the purchase if the problems are serious enough.

Step 7 — Exchange of Contracts
Exchange is the legally binding point. Both you and the seller sign identical contracts and they are exchanged between solicitors. At exchange, you pay your deposit — typically 10% of the purchase price — and a completion date is set.
After exchange, neither party can withdraw without significant financial penalty. If you pull out, you lose your deposit. If the seller pulls out, they are typically liable for your wasted costs and potentially more.
Conveyancing typically takes 12 to 16 weeks from offer acceptance to exchange, though delays are common — only 29% of transactions complete within 12 weeks according to 2025 data. The main causes of delay are:
- Local authority search backlogs (some councils still take over 50 days)
- Slow mortgage processing
- Chain delays — any hold-up in another transaction in the chain affects yours
- Legal issues such as title defects, missing documents, or leasehold complications
Step 8 — Completion
Completion is when you legally become the owner. Your solicitor transfers the purchase funds to the seller’s solicitor. Once received, the estate agent releases the keys. This is typically one to two weeks after exchange.
On completion day:
- Your solicitor registers your ownership with HM Land Registry
- SDLT is paid on your behalf by your conveyancer
- Your mortgage begins

How Long Does the House Buying Process Take?
From offer acceptance to completion, the average is 14 to 22 weeks. First-time buyers with no chain often complete in 12 to 16 weeks. Complex chains, leasehold complications, or survey issues can extend this to six months or more.
From starting your property search to getting the keys — including finding a property — the total process is typically four to nine months.

Conclusion
The house buying process in the UK involves more professionals, more stages, and more time than most first-time buyers anticipate. The decisions that have the most impact on outcome — using a whole-of-market mortgage broker, commissioning the right level of survey, instructing your conveyancer the day an offer is accepted — are all made in the first two weeks after offer acceptance. Understanding the sequence before you start means fewer surprises and a faster, smoother process.
Frequently Asked Questions
How long does the house buying process take in the UK?
From offer acceptance to completion, the process typically takes 14 to 22 weeks. First-time buyers without a chain often complete in 12 to 16 weeks. Including the property search, most buyers complete between four and nine months after they begin looking seriously.
When do I need to pay my deposit when buying a house?
Your deposit — typically 10% of the purchase price — is paid at exchange of contracts, not at offer or at completion. This is the legally binding point at which you and the seller are both committed to the transaction, and pulling out after exchange means losing your deposit.
What is the difference between exchange and completion?
Exchange is when both parties sign contracts and are legally committed — usually one to two weeks before completion. Completion is when the funds transfer and you legally become the owner of the property and receive the keys.
