Buying a house in the UK is easier to manage when you treat it as a sequence of decisions rather than one large event. This practical house buying timeline takes you from an accepted offer to completion, explains what happens at each stage, highlights the documents and costs to track, and gives you a simple way to estimate your own likely timetable.
Overview
The period after an offer is accepted is usually described as “under offer” or “sold subject to contract”. In most of the UK, the transaction is not legally binding at this point. Until contracts are exchanged, either side may be able to withdraw, and another buyer may still make an offer. Scotland has a different process, including the potential use of “missives”, so Scottish buyers should check the exact procedure with their solicitor.
A typical purchase moves through these stages:
- Offer accepted and a solicitor or conveyancer instructed.
- Full mortgage application submitted, if borrowing is required.
- Survey and lender valuation arranged.
- Property searches, title checks and enquiries completed.
- Mortgage offer issued and conditions reviewed.
- Exchange of contracts, followed by a fixed completion date.
- Completion, collection of keys and moving into the property.
There is no guaranteed timetable. A straightforward chain-free purchase may progress relatively quickly, while a property with a long chain, leasehold issues, missing documents or delayed searches can take considerably longer. Your target should therefore be a sequence of completed tasks, not a single promised completion date.

How to estimate your house buying timeline
Build your estimate by listing each stage, its likely duration and the dependency that could delay it. A simple worksheet might look like this:
| Stage | What to track | What may delay it |
|---|---|---|
| Instruction | Client care documents, identity checks and payment on account | Incomplete forms or difficulty verifying identity |
| Mortgage | Application, supporting evidence and formal offer | Missing payslips, complex income or property concerns |
| Survey | Survey type, inspection date and report | Surveyor availability or significant defects |
| Searches | Local, drainage, environmental and any additional searches | Local authority processing times or unusual property risks |
| Legal enquiries | Replies from the seller’s solicitor and review of title | Leasehold information, alterations or missing certificates |
| Exchange | Signed contracts, deposit and agreed completion date | Unresolved enquiries, chain members or mortgage conditions |
| Completion | Funds transferred, keys released and final arrangements | Banking delays, chain coordination or outstanding funds |
Use the slowest realistic dependency as your working estimate. For example, there is little value in booking removals for a particular date if the mortgage offer is not yet issued or the chain has not agreed completion dates. Ask your conveyancer for a written list of outstanding items and update it after every significant call or email.
Keep a separate cost tracker. Include the deposit, mortgage fees, lender valuation or survey costs, conveyancing fees, searches, removals, insurance, repairs and any applicable property tax. A Lifetime ISA withdrawal, gifted deposit or sale of another property may have its own timing requirements, so confirm these before setting an exchange date.
Inputs and assumptions
Your estimate will be more useful if you record the factors that affect it:
- Location: the legal process differs between England and Wales, Scotland and Northern Ireland. Confirm the relevant procedure for the property’s location.
- Chain position: a chain-free purchase is usually easier to coordinate than a linked series of sales and purchases.
- Tenure: leasehold purchases can require additional information about the lease, service charges, insurance and management arrangements. Read our guide to leasehold and freehold if you need to compare the two.
- Finance: allow time for a full mortgage application even if you already have an agreement in principle. The lender may still assess your income, commitments and the property itself.
- Property condition: a survey can reveal repairs or legal questions that need investigating before you proceed.
- Personal deadlines: consider a tenancy end date, school term, work commitments, storage and removal availability.
Do not treat an agreement in principle, a satisfactory survey or a verbal assurance from an estate agent as a guarantee that the purchase will complete. Keep your finances stable, avoid taking new credit without discussing it with your mortgage adviser, and do not give notice on a rental property until your legal and mortgage position is sufficiently secure.
Worked examples
Example one: chain-free first-time buyer
A first-time buyer has an accepted offer on a freehold property. They instruct a conveyancer immediately, send identification and financial documents on the same day, book a survey promptly and submit the full mortgage application. Searches and enquiries then run in parallel. In this case, the main calculation is the sum of the individual stages, with a contingency for lender, search and solicitor responses. The buyer should still avoid committing to a non-refundable moving date until exchange.
Example two: leasehold purchase in a chain
A buyer is purchasing a flat from a seller who is also buying elsewhere. The buyer’s solicitor must review the lease and obtain information about the building and management arrangements, while the chain must coordinate several transactions. Even if the buyer’s own mortgage and survey are complete, exchange may wait for an unresolved leasehold enquiry or another chain member. Here, the practical estimate should be based on the outstanding chain and legal issue, not on the date the offer was accepted.
Example three: survey identifies work
If a survey reports damp, roof concerns or alterations that need evidence, pause the timetable and obtain appropriate advice. You may renegotiate, ask for documents, commission a specialist report or withdraw before exchange. Add the cost and time of these investigations to your worksheet rather than assuming they will be resolved automatically.
When to recalculate
Revisit your timeline whenever an input changes. The most important triggers are a revised mortgage rate or loan amount, a change in purchase price, a survey finding, a new search result, a delayed chain member, a change in the completion date, or a new estimate of conveyancing and moving costs. Check tax assumptions against the current rules for the property’s location rather than relying on an old stamp duty calculator result.
Use this final checklist before exchange:
- Your mortgage offer is issued and its conditions are understood.
- Your survey findings have been reviewed and any necessary specialist reports obtained.
- Your solicitor has completed title checks, searches and key enquiries.
- You understand the tenure, lease obligations, boundaries and included fixtures.
- You have calculated the money needed for exchange, completion, tax and immediate repairs.
- The chain has agreed a realistic completion date.
- You understand that exchange creates a substantially firmer legal commitment than an accepted offer.
After exchange, arrange insurance and removals for the agreed date, confirm how and when keys will be released, and keep funds available for completion. On completion, your conveyancer confirms that the purchase money has been transferred; the estate agent can then normally release the keys. Keep your completion statement, mortgage documents, guarantees and property information together so they are easy to find after moving day.
For the practical final stage, use a moving house checklist, and revisit your budget if mortgage rates, tax rules or supplier costs change before completion.
