The Typical Timeline: Week by Week
In an ideal scenario — no chain, freehold property, responsive solicitors on both sides, and a mortgage agreed in principle — the process from accepted offer to completion takes roughly 12 weeks. The first two weeks involve instructing your solicitor and formally applying for your mortgage. Weeks 3 to 6 cover the survey, local authority searches, and the solicitor raising initial enquiries with the seller's side.
Weeks 7 to 10 are typically spent resolving enquiries — questions about boundaries, planning history, guarantees for any works done, fixtures and fittings. Once all enquiries are satisfied, you move to exchange of contracts (when the purchase becomes legally binding) and agree a completion date, usually 1 to 4 weeks after exchange.
| Stage | Typical Duration | What Happens |
|---|---|---|
| Instruct solicitor | Week 1–2 | Engagement letter, ID checks, mortgage application submitted |
| Searches & survey | Week 3–6 | Local authority, environmental, water searches; surveyor visits property |
| Enquiries | Week 6–10 | Solicitors exchange questions about title, boundaries, planning, works |
| Exchange of contracts | Week 10–12 | Deposit paid (usually 10%), completion date set, legally binding |
| Completion | Week 12–16 | Remaining funds transferred, keys handed over, you move in |
What Slows Things Down
Chains are the single biggest source of delay. If your seller is buying another property, and that seller is also buying, each link in the chain must be ready before anyone can exchange. One slow solicitor, one delayed mortgage offer, or one unresolved enquiry anywhere in the chain holds up everyone. Chains of four or more parties regularly take 20+ weeks.
Leasehold purchases are inherently slower than freehold. Your solicitor needs to review the lease, obtain a management pack from the freeholder or managing agent (which can take 3–6 weeks and costs £300–£600), and check for any issues with ground rent, service charge arrears, or forthcoming major works. If the lease needs extending, add months.
Local authority searches in some areas — particularly rural councils and those with backlogs — can take 6 to 8 weeks instead of the typical 2 to 3. Your solicitor can use personal search insurance as an alternative, but not all mortgage lenders accept this.

Cash buyers genuinely do complete faster — typically 6 to 8 weeks — because they remove the mortgage application, valuation, and underwriting stages entirely. This is why sellers often accept a lower offer from a cash buyer: the certainty and speed have real value.
However, cash doesn't eliminate all delays. Searches, solicitor enquiries, and chain dependencies still apply. A cash buyer purchasing from a seller who is buying their next property with a mortgage is still constrained by that mortgage timeline.
How to Speed Up Your Purchase
The most effective things you can do are all about preparation. Instruct a solicitor before you find a property — many will hold your file open at no cost until you have an accepted offer. Get your mortgage agreement in principle sorted and your deposit funds verified (anti-money-laundering checks on source of funds can add weeks if you leave them late).
Once the process is underway, chase proactively but politely. Ask your solicitor for a weekly update email and don't assume silence means progress. Respond to any requests for information the same day. If you are in a chain, your estate agent should be coordinating progress across all parties — hold them to that.
- ►Instruct a solicitor early: Have a solicitor ready to act the day your offer is accepted. Comparing quotes after the event wastes the first week.
- ►Prepare proof of funds: Bank statements, gift letters, and AML documentation take time to gather. Have them ready before you need them.
- ►Book your survey immediately: Don't wait for searches to come back before booking a survey. Run them in parallel to save 2–3 weeks.
- ►Be responsive: Every day you take to return a signed form or answer a query adds a day to the process. Treat it like a project with a deadline.
