The typical transaction timeline
Once your offer is accepted, the transaction moves through a sequence of legal and administrative stages. Weeks 1 to 2: instruct your solicitor, complete mortgage application in full if not already done. Weeks 2 to 5: solicitor commissions searches (local authority, drainage, environmental), reviews title documents, and raises enquiries with the seller's solicitor. Mortgage lender commissions its own valuation. Weeks 4 to 8: searches return, enquiries answered, mortgage offer formally issued. Survey commissioned and completed. Weeks 8 to 12: solicitor reports to you on the title and search results, you review mortgage offer, both sides' solicitors agree a completion date and exchange contracts. Exchange is legally binding.
Completion — the day you hand over money and get the keys — typically happens 7 to 28 days after exchange. Many buyers aim for a two-week gap to arrange removals and final preparations. The full timeline from offer to keys is most commonly 12 to 16 weeks for a standard chain-free purchase.
What causes delays
The most common causes of delay in a property purchase are: slow search returns from local authorities (some councils take 4 to 8 weeks rather than 2); delays in the mortgage lender issuing a formal offer, particularly if additional underwriting documentation is required; unresolved enquiries where the seller cannot quickly provide documentation the buyer's solicitor has requested; and chain complications where another transaction in the chain is delayed.
Leasehold purchases add complexity at every stage: the managing agent needs to provide a management pack (typically 2 to 4 weeks and £200 to £600), lease terms may generate extended enquiries, and some leases require licence to assign documentation. Budget an extra 2 to 4 weeks for a leasehold transaction compared to a standard freehold.
How to speed up your purchase
Choose a solicitor who is responsive and experienced with the type of property you are buying. Online conveyancers are often cheaper but slower and less available for queries; a local solicitor with good communication is worth the slightly higher cost if you value speed. Instruct your solicitor and complete your full mortgage application as soon as your offer is accepted, rather than waiting to confirm details.
Respond to your solicitor's requests promptly. Every day of delay in providing documentation extends your timeline by at least one day, often more due to solicitor workload. If you are in a chain, speak to your estate agent regularly about the status of other transactions in the chain and flag any concerns early.
The difference between exchange and completion
Exchange of contracts is the point at which both buyer and seller are legally committed to the transaction. Before exchange, either party can walk away without financial penalty (though you will lose your solicitor's costs and survey fees). After exchange, withdrawing incurs serious financial consequences: the buyer forfeits their deposit, and the seller can claim damages.
Completion is when the purchase funds transfer and you receive the keys. The Land Registry registers your ownership in the weeks following completion. Until Land Registry registration is complete, you own the property but your ownership is not yet recorded on the public register — this is normal and your solicitor will manage the registration process. First registration typically takes 4 to 8 weeks; re-registration on an existing title is usually faster.
Frequently asked questions
Can you speed up a house purchase to complete in under 8 weeks?
Yes, but it requires everything to go smoothly. Searches need to return quickly, the mortgage offer needs to issue promptly, and there must be no complications in the title or enquiries. Cash purchases with no chain can sometimes complete in 4 to 6 weeks. Mortgage purchases in simple chains occasionally complete in 8 to 10 weeks. It is rare but achievable if all parties are motivated.
What happens if the seller pulls out before exchange?
Before exchange, either party can walk away without legal liability to the other. You cannot force a sale. You would lose your survey costs and solicitor's fees to date, which is typically £1,000 to £2,000. This is known as being 'gazumped' if a higher offer from another buyer is the cause. Scotland uses a different system where an offer once formally accepted is more binding.
