Offer to Completion: UK Homebuying Timeline Checklist and Transaction Tracker
Once an offer is accepted, the purchase moves from property hunting into a sequence of legal, financial and practical checks. This offer-to-completion timeline explains what usually happens next, who is responsible, what documents are needed and how to track progress without treating an accepted offer as a guaranteed sale.
Overview
The period between an accepted offer and completion is often described as the conveyancing process. It includes the buyer’s legal checks, the seller’s replies to enquiries, property searches, mortgage underwriting, the survey, contract approval, exchange of contracts and finally completion.
There is no single UK-wide process. England and Wales generally use exchange of contracts followed by completion. Scotland has a different system based around missives, while Northern Ireland has its own conveyancing practice. The checklist below is therefore mainly framed around England and Wales. Ask your solicitor or licensed conveyancer how the process differs in your jurisdiction.
A straightforward transaction may take several weeks, but chains, leasehold paperwork, unusual title issues, slow searches, mortgage delays or renegotiation can make it longer. The most useful approach is to track dependencies rather than rely on a single target date.
Offer-to-completion tracker
| Milestone | Typical responsibility | What to record |
|---|---|---|
| Offer accepted | Buyer, seller and agents | Price, inclusions, chain position and target dates |
| Instruct conveyancer | Buyer and seller | Firm details, quote, identification and client account information |
| Mortgage application | Buyer and lender | Application date, valuation date and outstanding documents |
| Survey and valuation | Buyer, surveyor and lender | Inspection type, findings and follow-up questions |
| Searches and enquiries | Conveyancers and relevant authorities | Searches ordered, results received and enquiries answered |
| Mortgage offer | Lender and buyer | Offer date, conditions and expiry date |
| Contract approval | Buyer’s conveyancer | Title issues, fixtures, replies and agreed amendments |
| Exchange | Both conveyancers | Signed contracts, deposit, completion date and confirmation |
| Completion | Buyer’s lender and conveyancer | Funds sent, keys released and handover confirmed |
Keep the tracker in one place. Add the date of every update, the person responsible for the next action and the consequence of delay. This turns vague chasing into a useful question: “What is outstanding, who has it and when will it be reviewed?”
How to estimate the timeline
Start with the intended completion date and work backwards. Allow time for the legal pack, searches, mortgage processing, survey follow-up and any chain above or below you. Your conveyancer may give a broad estimate, but the actual sequence depends on how quickly information is supplied and whether an issue needs specialist advice.
- Immediately after acceptance: confirm the agreed price and what is included, then instruct a conveyancer. Send identification, proof of address, source-of-funds evidence and details of your mortgage or deposit.
- During the first stage: submit the full mortgage application, arrange the survey and ask the seller’s side when the draft contract pack will be issued.
- Once the pack arrives: your conveyancer checks the title, plan, property information forms, fixtures and fittings list, lease or management information where relevant, and any restrictions or rights affecting the property.
- Search stage: common searches can include local authority, drainage and water, and environmental searches. Additional searches may be sensible because of the property’s location or history. Your conveyancer should explain what is appropriate.
- Enquiries and decisions: review survey findings, search results and legal replies. Resolve defects, request documents, renegotiate only where justified and confirm that your mortgage offer meets the purchase requirements.
- Exchange: exchange normally makes the contract binding. Do not assume you can safely book removals or treat a completion date as fixed until your conveyancer confirms exchange.
- Completion: the lender and buyer provide the balance of funds, the conveyancer sends the purchase money and the seller authorises release of the keys. Registration and post-completion tax or reporting work follows.

Inputs and assumptions
Your estimate should be based on the facts of the specific purchase, not a generic online timeline. Record these inputs before setting a target date:
- Property type: freehold, leasehold, shared ownership, new build or another arrangement. Leasehold and managed properties may require extra information from a landlord or managing agent.
- Chain position: a chain can create dependencies because several buyers and sellers must be ready at the same time.
- Mortgage status: an agreement in principle is not the same as a formal mortgage offer. Note the lender’s outstanding requirements, valuation position and offer expiry date.
- Legal documents: check whether the draft contract, title documents, property forms, lease and management information have been received.
- Search availability: turnaround varies by location and search provider. Your conveyancer can advise whether a search result needs clarification or replacement.
- Survey outcome: a survey may lead to further inspections, quotes, legal enquiries or a decision to proceed on revised terms. Compare survey options in our guide to UK home survey types.
- Funds and tax: budget for the deposit, balance of purchase price, conveyancing costs, search fees, lender charges, survey costs, removals and applicable property taxes. Check current thresholds and reliefs using an up-to-date official calculator rather than relying on an old example.
Do not use the tracker to give legal approval. It is a communication and planning tool. Your conveyancer must interpret the title, contract, searches and replies for your purchase. For leasehold properties, review the lease term, service charges, ground rent provisions, restrictions and planned major works; the seller’s documents may not answer every question immediately. See the leasehold versus freehold comparison for a due-diligence framework.
Worked examples
Example one: uncomplicated freehold purchase
A buyer has an accepted offer, a completed agreement in principle and a deposit ready. They instruct a conveyancer promptly, book a survey, submit the full mortgage application and provide source-of-funds evidence. Searches return without significant issues, the seller’s replies are complete and the lender issues the mortgage offer. The remaining tasks are contract approval, signing, agreeing a completion date and exchange. In this situation, the tracker should show several parallel workstreams rather than a queue: the survey, mortgage and legal checks can progress at the same time.
Example two: leasehold purchase in a chain
A buyer’s survey is satisfactory, but the management information is incomplete and the lease raises questions about alterations. The conveyancer requests documents and clarification while the mortgage offer approaches its expiry date. The tracker should flag three actions: chase the management pack, obtain evidence for the alterations and ask the lender or broker whether the offer can be extended or needs review. The buyer should avoid committing to a removal date until these issues and the chain position are clearer.
Example three: survey reveals a significant concern
A survey identifies a possible roof problem. The buyer asks for a specialist inspection and obtains an indicative repair cost. They then decide whether to proceed at the agreed price, renegotiate, request further evidence or withdraw before exchange. The tracker should record the decision deadline, the documents requested and any impact on the mortgage, insurance or completion target. A survey does not replace legal advice, and a lender’s valuation is not a full condition survey.
For budgeting alongside the tracker, review the guide to the cost of buying a house in the UK. Keep estimates separate from confirmed quotes, because fees and tax treatment depend on the transaction.
When to recalculate
Revisit the timeline and cost estimate whenever a material input changes. Recalculate if the price changes, the mortgage product or loan amount changes, the lender asks for more evidence, the mortgage offer is delayed or nearing expiry, a search or survey identifies a problem, the property changes from freehold to leasehold assumptions, or a chain member changes their target date.
Refresh tax and fee assumptions before exchange, particularly if the purchase date moves across a change in published thresholds, reliefs, lender charges or local search fees. Confirm the position with your conveyancer and lender rather than relying on a calculator saved from an earlier transaction.
Use this final action list at each weekly review:
- Write down the current milestone and the next decision.
- Mark every outstanding item as buyer, seller, conveyancer, lender, agent or third party.
- Give each item a chase date and a consequence if it remains incomplete.
- Check the mortgage offer, funding, deposit and identity documents again.
- Confirm whether searches, survey issues and enquiries are fully resolved.
- Ask whether the proposed completion date is realistic for the whole chain.
- Do not exchange until you understand the contract, have suitable funds and are ready to become legally bound.
Save a copy of the completed tracker with your purchase papers. It can help you explain delays, spot missing documents and prepare for a future move or remortgage, while your conveyancer remains the source of transaction-specific legal advice.
