UK Conveyancing Timeline From Offer to Keys for Flat Buyers

Everyone quotes you twelve weeks. Sometimes it is twelve weeks. Often it is sixteen, eighteen, or longer. The honest answer is that conveyancing on a flat takes as long as the slowest person in the chain, and there are more slow people involved in a leasehold purchase than most first-time buyers expect.

The headline stages are instructing solicitors, carrying out searches, reviewing the lease and management pack, raising enquiries, exchanging contracts, and then completing. Each one sounds tidy. None of them are. Between each stage there is a gap where your file sits in someone's inbox waiting to be picked up, and those gaps are where the weeks quietly disappear.

Knowing what is supposed to happen at each stage, and roughly when, means you can spot when something has stalled and actually do something about it rather than just hoping.

The moment your offer is accepted, instruct a solicitor the same day. Do not wait for the estate agent to send a memorandum of sale. Do not wait to see if the seller moves first. Get your solicitor instructed, your ID verified, and your source-of-funds documents ready immediately. This alone can save you a week.

Your solicitor will apply for the official title documents from HM Land Registry and wait for the seller's solicitor to send across the draft contract pack. That pack includes the draft contract itself, the title register, the property information form, the fittings and contents form, and for a flat it must also include the lease and the management pack from the freeholder or managing agent.

The management pack is one of the biggest delay points in any flat purchase. The freeholder or managing agent can take anywhere from two weeks to six weeks to produce it, and they are under no legal obligation to rush. Some managing agents charge the seller a fee to produce it, and if the seller hasnt paid that fee promptly, nothing moves. Ask your estate agent on day one whether the management pack has been ordered. If it hasnt, make some noise.

While you are waiting for the contract pack, your solicitor should be ordering searches. The three standard ones are a local authority search, a drainage and water search, and an environmental search. For a flat in a city you might also need a chancel repair search or a flood search depending on location.

Local authority searches are the most variable in timing. Some councils turn them around in a few days. Others take four to six weeks. Your solicitor should know the typical turnaround for your local council and can often use a personal search agent to speed things up, though this costs a little more.

Searches are not just a box-ticking exercise. They tell you whether there are planning permissions nearby that could affect your view or the building, whether the road outside is adopted by the council, and whether there are any enforcement notices on the property. Read the results when they come back. Your solicitor will flag anything serious, but it pays to understand what you are looking at.

This is where buying a flat diverges significantly from buying a house. Your solicitor needs to review the lease in detail. They will be checking the length of the term remaining, the ground rent provisions, the service charge history, what the lease says about alterations, subletting, and keeping pets, and whether there are any unusual or onerous clauses.

If the lease has fewer than around eighty years remaining you should know about this before you go any further, because mortgage lenders get uncomfortable below that point and it affects your ability to sell in future. Your solicitor should flag this immediately.

Once the contract pack and searches are in, your solicitor raises enquiries with the seller's solicitor. This is a formal written question-and-answer process. Some enquiries are standard. Others arise from specific things in the title or the lease. The seller's solicitor has to get answers from the seller and sometimes from the freeholder too, and this back-and-forth can take two to four weeks on its own.

If enquiries are going slowly, ask your solicitor to chase. A polite but firm phone call from your solicitor to the other side often moves things faster than another email.

Your mortgage lender will instruct a valuation surveyor to inspect the flat. Once they are satisfied, they issue a formal mortgage offer in writing. Your solicitor then needs to review the mortgage offer, report to you on the full transaction, and get your signature on the contract and the mortgage deed.

Do not sit on documents. When your solicitor sends you a report and asks for signatures, turn it around within twenty-four hours if you can. Buyers who take a week to return paperwork are the ones who then complain that conveyancing takes forever.

Your solicitor will also carry out a final check with the Land Registry to make sure nothing has changed on the title since the process began, and will request a redemption statement from the seller's mortgage lender if the seller has a mortgage to pay off. All of this needs to be done before exchange.

Exchange of contracts is the moment the sale becomes legally binding. Before exchange, either party can walk away. After exchange, you cannot without serious financial consequences. On exchange you pay your deposit, typically ten percent of the purchase price, though this can sometimes be negotiated lower. That money is at risk if you pull out after exchange without a valid legal reason.

Completion is the day the remaining money moves, the seller vacates, and you get the keys. The gap between exchange and completion is usually one to four weeks. Some buyers choose to exchange and complete on the same day, which removes the risk of the period in between but requires everyone to be ready simultaneously, which is stressful.

On completion day your solicitor sends the purchase funds to the seller's solicitor by bank transfer. Once the seller's solicitor confirms receipt, the estate agent releases the keys. Then your solicitor registers your ownership at HM Land Registry, which can take several weeks but does not affect your ability to move in.

The management pack. Chase it from day one. If the seller hasnt ordered it within the first week of your offer being accepted, ask the estate agent to push.

Slow local authority searches. Ask your solicitor upfront how long your council takes and whether a personal search is worth paying for.

Enquiries going in circles. If the same question keeps getting a vague answer, ask your solicitor to request a direct conversation with the other side rather than another written exchange.

Mortgage offer delays. If your lender is slow to instruct a valuation, call them. Lenders have customer service lines and they do respond to polite pressure.

Your own response time. Every time your solicitor asks you for something, treat it as urgent. One day of delay on your side can mean a week of delay overall.

The estate agent is your ally here. A good agent wants the sale to complete and will chase both sides on your behalf. Use them. Call them weekly for an update and ask specifically what the current blocker is. Vague reassurances are not useful. A specific answer about what is outstanding and who is responsible for it is.
