The realistic timeline
From an offer being accepted to completion, a typical purchase in England and Wales takes somewhere around four to six months, though it ranges widely. Simple, chain-free purchases with a ready buyer can complete in a couple of months; long chains, leasehold flats or problem titles can drag well beyond six.
The visible milestones are: offer accepted, conveyancer instructed, searches ordered and returned, mortgage valuation and offer, enquiries raised and answered, then exchange of contracts (the binding moment) and finally completion. Each step depends on the one before, which is why a single slow link holds up everything.
What slows it down
The biggest delays are usually the chain (every linked sale must be ready to exchange together), local authority search turnaround (which varies by council), mortgage underwriting, and leasehold management packs — freeholders and managing agents can take weeks to supply the information a buyer's solicitor needs.
Problems surfacing late are another classic cause: an unexpected covenant, a planning issue, a survey defect or a title query can each trigger rounds of enquiries. Many of these are knowable from the public record before you offer, which is why front-loading diligence shortens the back half of the process.
How to speed it up
Get a mortgage agreement in principle before you offer, instruct your conveyancer the moment your offer is accepted, and return your ID and paperwork promptly. Order searches early and stay responsive to your solicitor's enquiries — buyer-side delays are often self-inflicted.
Doing your homework before you offer also helps: if you already understand the property's flood, planning, title and price position, there are fewer late surprises to investigate. A TrueBrick report front-loads that public-record check, so you reach exchange with fewer questions outstanding.
Is the process getting faster?
The government's home-buying reform roadmap is explicitly aimed at cutting delays and fall-throughs — through upfront 'sales pack' information and, eventually, earlier binding commitment. The intent is to move diligence before the offer so the post-offer phase is quicker and more certain.
That's a gradual change rather than an overnight one, but the direction rewards prepared buyers now. The more you know before you commit, the less time you'll spend discovering things after.
Frequently asked questions
How long from offer to exchange of contracts?
Often eight to twelve weeks, but it depends on searches, the mortgage, the chain and how quickly enquiries are answered. Exchange is the point at which the sale becomes legally binding.
What's the difference between exchange and completion?
At exchange you sign binding contracts and pay your deposit — neither side can pull out without penalty. Completion is when the money transfers and you get the keys, usually one to four weeks later (sometimes the same day).
Can I speed up conveyancing searches?
Partly. Ordering them immediately after offer acceptance is the main lever; some councils are slower than others. Screening the public record before you offer means fewer surprises to chase once searches return.
