How Long Does the Conveyancing Process Usually Take in London from Offer Accepted to Completion

Conveyancing is the legal process of transferring ownership of a property from seller to buyer. It covers everything from the initial contract pack prepared by the seller's solicitor through to the registration of the new owner at HM Land Registry. In London, the process typically runs longer than the UK national average of around 10 to 12 weeks, with most transactions in the capital completing in 12 to 20 weeks from offer accepted to completion.

The Legal Transfer of Ownership Explained

The conveyancing process splits into two distinct phases. The first is the pre-exchange period, where solicitors carry out searches, raise enquiries, and satisfy the mortgage lender's requirements. The second is the post-exchange period, which is usually short, running from exchange of contracts to completion day. Once contracts are exchanged, both buyer and seller are legally committed to the transaction and a completion date is fixed.

According to Kreston Solicitors, London transactions consistently run at the longer end of the national range because of the complexity of the housing stock, the prevalence of leasehold titles, and the sheer number of parties involved in a typical chain.

Why London Chains Are Longer and More Complex

A London property chain can involve four, five, or even six linked transactions. A first-time buyer purchasing a flat in Hackney may be enabling a second-step buyer in Walthamstow to move to a semi-detached in Chingford, who in turn is freeing up a family home in Enfield. Every link in that chain must reach exchange simultaneously, which means the slowest solicitor or the most complex title sets the pace for everyone.

London also has a very high proportion of leasehold properties. Flats in purpose-built blocks across areas like Canary Wharf, Stratford, and Battersea are almost always leasehold, and the additional legal work involved in reviewing the lease, obtaining management company information packs, and checking service charge accounts adds weeks to the process that a freehold house purchase simply does not require.

2. The Full Conveyancing Timeline from Offer Accepted to Completion in London

The conveyancing process usually takes 12 to 20 weeks in London from offer accepted to completion, but each stage has its own rhythm. Understanding what happens in each window helps you anticipate hold-ups before they become costly.

Weeks 1 to 4: Instructing Solicitors and Initial Searches

The clock starts the moment the agent issues the memorandum of sale. Both buyer and seller instruct their solicitors, who then request and issue the contract pack. The buyer's solicitor submits searches to the relevant London borough council, which can include a local authority search, drainage and water search, and environmental search. In September 2026, local authority search turnaround times vary considerably across London boroughs, with some inner London councils returning results in five to ten working days and others taking three to four weeks.

The buyer's solicitor also sends a formal request for ID and anti-money-laundering documents from the buyer at this stage. Delays here are common and entirely avoidable. Having your passport, proof of address, and source-of-funds evidence ready on day one can save a week or more.

Weeks 4 to 10: Enquiries, Surveys, and Mortgage Offers

Once searches return and the contract pack is reviewed, the buyer's solicitor raises written enquiries with the seller's solicitor. These can range from questions about planning permissions for a rear extension in Islington to queries about a shared boundary wall in Peckham. The seller's solicitor must answer each one satisfactorily before the buyer's solicitor will recommend exchange.

This is also when the buyer arranges a surveyor. A HomeBuyer Report or a full structural survey on a Victorian terrace in Lewisham or an Edwardian conversion in Crouch End can take one to three weeks to book and receive, depending on surveyor availability. If the survey flags issues, a renegotiation on price or a request for remedial work adds further time before the transaction can progress.

The mortgage lender conducts its own valuation during this period. Formal mortgage offers from high-street lenders in the UK are currently taking between two and six weeks to issue from application, and the offer must be in place before the buyer's solicitor can report to the client and recommend exchange.

Weeks 10 to 16: Exchange of Contracts

Exchange of contracts is the legal point of no return. The buyer pays a deposit, typically 10% of the purchase price, which is held by the seller's solicitor. A completion date is agreed by all parties in the chain. In London, the gap between exchange and completion is commonly one to four weeks, though some buyers and sellers prefer a longer run to arrange removals, give notice on a rental, or synchronise with a school term.

Simultaneous exchange across a long chain requires all solicitors to be available and ready on the same day. This coordination alone can push exchange back by one to two weeks beyond what any individual solicitor expects, simply because one party in the chain is not ready.

Weeks 16 to 20 and Beyond: Completion Day

Completion day is when the balance of the purchase price is transferred and the keys are released. The buyer's solicitor sends the funds to the seller's solicitor, who confirms receipt before the estate agent releases keys. In a chain, this process happens sequentially from the bottom up, which means buyers at the top of a chain sometimes wait until mid-afternoon on completion day before they can collect keys, even if their own funds transferred that morning.

After completion, the buyer's solicitor registers the new ownership at HM Land Registry. Current Land Registry processing times in September 2026 are running at several weeks for straightforward registrations and several months for complex leasehold titles, though this does not affect the buyer's ability to move in and use the property.

3. What Causes Conveyancing Delays in London

Most London conveyancing delays fall into a handful of predictable categories. Knowing them in advance means you can ask the right questions early and reduce the risk of your transaction stalling.

Leasehold Properties and Freeholder Complications

Leasehold is the single biggest source of delay in London conveyancing. The seller must obtain a leasehold information pack from the freeholder or managing agent, which sets out service charges, ground rent, building insurance, and any planned major works. Some managing agents in London take four to six weeks to return these packs, and some charge fees of several hundred pounds for the privilege. If the lease has fewer than 80 years remaining, the buyer's mortgage lender may require a lease extension to be negotiated before it will lend, adding months to the timeline.

Flats in converted Victorian houses, which are extremely common across south and east London, often have informal or poorly drafted leases. A solicitor spotting a defect in the lease title, such as missing landlord covenants or an unclear repairing obligation, will raise additional enquiries that can take weeks to resolve.

Chain Collapses and Gazumping

London's competitive property market means chains can collapse or be disrupted even after weeks of legal work. Gazumping, where a seller accepts a higher offer from a new buyer after already accepting yours, remains a risk until exchange of contracts because there is no legal commitment before that point. In a rising market, this can set a buyer back to square one after eight to ten weeks of legal fees and survey costs.

A chain break lower down, such as a buyer losing their mortgage offer or a seller deciding not to move, can also delay every transaction above it by weeks or months while a replacement buyer or property is found.

Local Authority Search Backlogs in London Boroughs

Search turnaround times vary widely between London's 32 boroughs. Some boroughs consistently return local authority searches within five to seven working days. Others, particularly those with higher transaction volumes or less-digitised records, can take three to five weeks. Your solicitor should be able to advise on current turnaround times for the specific borough you are buying in, and in some cases may recommend an insurance-backed personal search as a faster alternative.

4. How to Speed Up Your London Conveyancing

There are concrete steps buyers and sellers can take to keep the conveyancing process moving. None of them are complicated, but most people only discover them after their first transaction has already run long.

Choose a Solicitor Who Knows the London Market

A solicitor with an active London caseload knows which managing agents are slow, which boroughs have search backlogs, and which title issues are common in specific areas. A solicitor based outside London handling London conveyancing remotely is not necessarily a problem, but you should ask directly how many London transactions they complete each month and whether they have handled leasehold titles in the borough you are buying in. Price should not be the only factor: a cheap solicitor who takes three weeks to respond to enquiries will cost you more in the end.

Get Your Documents Ready Before the Offer Is Accepted

Sellers can prepare a draft contract pack before the property even goes on the market. This means the moment an offer is accepted, the buyer's solicitor receives the title documents, the TA6 property information form, and the TA10 fittings and contents form within days rather than weeks. For leasehold sellers, ordering the management information pack at the point of listing rather than after offer acceptance can save three to four weeks on its own.

Buyers should apply for their mortgage in principle before making an offer and have their full mortgage application submitted within the first week after offer acceptance. Lenders require payslips, bank statements, and proof of deposit, and gathering these after the fact is one of the most common causes of a mortgage offer arriving late and delaying exchange.

Keep Communication Flowing Between All Parties

The conveyancing process stalls most often when parties stop chasing. Solicitors carry large caseloads and your transaction will not always be the most urgent file on their desk. A polite weekly call or email to your solicitor asking for a progress update is entirely reasonable and often prompts action. Your estate agent can also play a valuable role in chasing the chain, as they have relationships with all the agents involved and a direct interest in the transaction completing.

According to data reviewed by weMOVEtogether's 2026 conveyancing report, transactions where buyers and sellers proactively chased their solicitors at least once per week completed on average two to three weeks faster than those where communication was left entirely to the legal teams.

5. Conveyancing Costs in London: What to Budget

Conveyancing costs in London are higher than the national average, reflecting the higher property values and the greater complexity of many London titles. Budgeting accurately from the start avoids surprises at a point in the process when you have already committed financially.

Solicitor Fees and Disbursements

Solicitor legal fees for a London property purchase typically range from around £1,500 to £3,500 plus VAT, depending on the purchase price and whether the property is freehold or leasehold. Leasehold purchases attract additional fees for reviewing the lease and dealing with the managing agent, often adding £300 to £600 to the base fee. Disbursements, which are third-party costs the solicitor pays on your behalf, include local authority searches (£150 to £350 depending on the borough), Land Registry fees (scaled by purchase price), and a bank transfer fee of around £30 to £50.

Sellers also pay conveyancing fees, though they tend to be lower than the buyer's costs because fewer searches are required. A seller's conveyancing quote in London typically runs from £1,000 to £2,500 plus VAT, again rising for leasehold titles where the seller must obtain and provide the management information pack.

Stamp Duty Land Tax Timelines and Deadlines

Stamp Duty Land Tax must be paid to HMRC within 14 days of completion. Your solicitor handles this submission on your behalf and will request the funds before or on completion day. For a first-time buyer purchasing a property in London at £500,000 in September 2026, no SDLT is payable on the first £425,000 and 5% applies to the portion between £425,001 and £500,000, resulting in a tax bill of £3,750. For a buyer who already owns a property, the additional-property surcharge of 3% applies to the full purchase price from the first pound.

SDLT thresholds and rates are set by Parliament and can change at Budget. Your solicitor will confirm the exact figure applicable to your transaction, but it is worth calculating a rough estimate early so the amount does not come as a shock alongside all the other completion-day costs.
