Nobody's conveyancing collapses on a Tuesday with a phone call and a clear explanation. It drifts. A search takes three weeks longer than anyone mentioned. A form sits in someone's inbox. You chase, you get a polite non-answer, and a purchase that was supposed to take ten weeks quietly becomes eighteen.
The frustrating part is that most of these delays are predictable. Solicitors see the same nine culprits on repeat, and almost every one of them can be shortened — or removed entirely — if you know it is coming. This guide names them, tells you why each one happens, and gives you the specific move that stops it costing you a month.
Quick answer: Conveyancing in England and Wales typically takes 12–16 weeks for a freehold property and 18–22 weeks for a leasehold, but most delays come from a handful of predictable bottlenecks: slow local authority searches, late leasehold management packs, gifted deposits declared late, missing building certificates, slow replies to enquiries, mortgage offer hold-ups, title problems, unresponsive parties, and delays elsewhere in the chain. The single most effective fix is front-loading — instruct your solicitor, order searches, and declare your funding position in the first week rather than waiting for milestones.
1. Local Authority Searches Ordered Too Late
Local authority searches check for planning issues, road schemes, and enforcement notices affecting the property. Some councils turn them around in five working days. Others take twenty-five or more, and in parts of London a search can add four to ten weeks to your timeline on its own. The problem is rarely the search itself. It is that many buyers wait until the mortgage offer arrives before authorising the search fee — so the slowest step in the whole process starts last.
Searches and mortgage applications can run in parallel. There is no rule that says one must finish before the other begins, only a habit of caution about spending £250 to £400 on a purchase that might fall through. That caution is understandable. It is also, on average, the more expensive choice.

2. The Leasehold Management Pack Nobody Has Ordered
If you are buying a flat, your solicitor cannot raise the detailed leasehold enquiries needed to exchange until the seller's side produces a management pack — service charge accounts, ground rent details, planned major works, the LPE1 form. Managing agents typically take two to six weeks to produce it, charge the seller £200 to £500 plus VAT for the privilege, and face no legal deadline whatsoever. Some sellers do not order it until their solicitor asks, which can be a month into the transaction.
This is the quiet delay behind the statistic that leasehold purchases take four to six weeks longer than freehold ones. It is also one of the few delays where a polite question from you, asked early, genuinely changes the outcome. Sellers are usually as keen to move as you are — they just do not always know the pack exists until it is already late.

3. Gifted Deposits Declared Late
If any part of your deposit is a gift — from parents, grandparents, anyone — your solicitor is legally required to verify where that money came from under anti-money laundering regulations, and your lender needs a signed gift declaration confirming the money is not a loan and the giver claims no stake in the property. The giver will need to provide ID, bank statements, and sometimes evidence of how they accumulated the funds. None of this is optional, and solicitors can be personally prosecuted for skipping it.
The delay happens when the gift surfaces three days before exchange, usually in a sentence beginning with 'oh, I should probably mention'. Then everything stops while a retired parent hunts for a paper bank statement and a declaration goes back and forth for signatures. Your parents' generosity deserves better than becoming the reason completion slipped a fortnight.

4. Missing Certificates for Past Building Work
Replacement windows need a FENSA or Certass certificate. A new boiler needs a Gas Safe record. An extension or loft conversion needs building regulations sign-off. When any of these are missing, the buyer's solicitor raises an enquiry, the seller goes hunting through drawers, discovers the installer went bust in 2014, and everyone spends two weeks arguing about who pays roughly £30 to £150 for an indemnity insurance policy instead of exchanging contracts.
Missing paperwork almost never kills a sale. Indemnity insurance exists precisely for this situation, and it is quick to arrange once everyone agrees. The delay is not the problem itself — it is the discovery of the problem in week nine rather than week one, and the slow negotiation that follows. Problems found early are admin. Problems found late are drama.

5. Protocol Forms Sitting on the Seller's Kitchen Table
Before the buyer's solicitor can do much of anything, the seller has to complete the property information form (TA6) and the fittings and contents form (TA10) — long, tedious documents asking about boundaries, disputes, alterations, and whether the curtain poles are staying. Nothing substantive starts until they are done. And because they are boring and slightly intimidating, they have a remarkable ability to sit untouched for two or three weeks while a whole transaction idles.
If you are the seller, these forms are the one part of conveyancing where your effort directly sets the pace. Fill them in honestly and thoroughly — vague answers just come back as enquiries, which is the same work done twice, slower. An evening with a cup of tea and the deeds folder now saves a fortnight of correspondence later.

6. The Mortgage Offer That Arrives Late — or Expires
Your solicitor cannot exchange contracts until your formal mortgage offer is issued and checked, so anything that slows the lender slows everything. Missing payslips, an undeclared bonus structure, a down-valuation, or a change in your circumstances mid-application can each add weeks. And offers do not last forever — most are valid for three to six months, which sounds generous until a slow chain means yours expires the week before exchange and the application has to be refreshed at current rates.
The lender is the one party in the chain who genuinely does not care about your moving date. That is not cruelty; it is process. Your job is to make yourself the most boring applicant they have seen all month — complete documents, no surprises, no new car on finance in month two.

7. Title Problems Nobody Spotted Early
Sometimes the delay is buried in the title itself: the property is unregistered, a previous owner's name is spelled two different ways, there is a restriction nobody remembered, or a slice of the garden turns out to belong to no one in particular. Unregistered titles are the heavyweight here — proving ownership from a bundle of old paper deeds takes real time, and HM Land Registry reports that a large share of applications need clarification before they can proceed.
Title problems are the least fair of the quiet delays, because you did nothing to cause them and can do little to fix them. What you can control is when they surface. A title checked in week one gives everyone three months to solve a problem. A title checked in week ten gives everyone a crisis.

8. Enquiries Ping-Pong
After the contract pack and searches arrive, the buyer's solicitor raises enquiries — questions about anything unclear. The seller's solicitor forwards them to the seller, waits, forwards the answers back, and the buyer's solicitor reads them and raises more. Each round trip can take one to two weeks, and a transaction with three lazy rounds of enquiries has quietly lost a month to what is essentially slow email. A national shortage of conveyancers — numbers fell around 15% between 2021 and 2025 — means files sit longer at every step.
You cannot answer the enquiries yourself, but you can compress the gaps between them. Most of the wasted time is not thinking time. It is waiting time — a question sitting unread while a caseworker handles forty other files. A weekly nudge, made politely and to the right person, moves your file up the pile more often than anyone likes to admit.

9. Someone Else's Delay Becomes Yours
The final quiet delay is the one you never see coming, because it is not in your transaction at all. Chains exchange together and complete together, so the slowest link sets the pace for everyone. Your searches can be back, your enquiries answered, your mortgage offer sitting pristine in a file — and you will still wait, because the buyer three houses up the chain has only just instructed a solicitor. Industry data now puts the average time to exchange at over 100 days, and long chains are a big reason why.
You cannot manage a stranger's purchase. But you can know it exists. Most buyers never ask how long the chain is or where the weak point sits, and so every delay arrives as a mystery. A chain you understand is still slow — but it is slow in a way you can plan around, which is a different thing entirely from waiting in the dark.
