How to Keep Your Sale on Track and Avoid Delays

Selling a house in the UK is rarely as smooth as anyone hopes. Even in a healthy market, the average sale takes three to six months from listing to completion — and a significant proportion fall through or stall along the way. The good news is that most delays are predictable, and most are preventable if you know what to look for.

Why do house sales take so long in England and Wales?

The UK's conveyancing system is one of the main structural reasons sales drag on. Unlike Scotland, where missives create a legally binding contract early in the process, in England and Wales neither party is committed until exchange of contracts — which typically happens only weeks before completion. That gap leaves plenty of room for things to unravel.

According to the Home Owners Alliance, the most common reasons sales fall through include:

• Buyers changing their minds (no legal obligation holds them until exchange)
• Survey results prompting renegotiation or withdrawal
• Mortgage offers being withdrawn or delayed
• Problems uncovered during conveyancing searches
• Chain collapses — where one linked transaction fails and brings others down

If you want a fuller picture of typical timelines, our article on how long it takes to sell a house in the UK breaks down each stage in detail.

How do you avoid delays before you even accept an offer?

The single most effective thing you can do to avoid delays is to instruct a solicitor and start gathering your paperwork before you accept an offer — ideally before you even go to market. Sellers who do this routinely shave three to six weeks off their completion timeline compared with those who wait.

Get your paperwork in order early

Your solicitor will need a range of documents to begin the conveyancing process. The sooner these are ready, the less time is lost waiting once a buyer is found. Documents to gather include:

• Title deeds — your solicitor or the Land Registry can obtain these, but allow time
• TA6 Property Information Form — covers boundaries, disputes, alterations and more
• TA10 Fittings and Contents Form — sets out what is included in the sale
• Planning permissions and building regulations certificates for any extensions or structural work
• Guarantees and warranties — FENSA certificates for windows, boiler service records, damp or timber treatment guarantees
• Leasehold documents (if applicable) — service charge accounts, ground rent details, management company information

Leasehold sales in particular are notorious for delays. Management companies can take weeks to respond to enquiries, so the earlier you request a leasehold information pack, the better.

Instruct a good solicitor, not just the cheapest one

Conveyancing quality varies enormously. A cheap, volume-based conveyancer handling hundreds of files simultaneously will rarely give your sale the attention it needs. Ask your estate agent for recommendations, check reviews, and confirm that your solicitor offers a direct contact — not just a generic inbox — so you can get real updates when you need them.

What causes delays after an offer is accepted?

Most avoidable delays happen in the conveyancing phase, between offer accepted and exchange of contracts. The common culprits are slow searches, unanswered enquiries and poor communication between parties.

Local authority and other searches

Local authority searches are ordered by your buyer's solicitor and can take anywhere from a few days to several weeks depending on the local council. Some areas are notoriously slow. Sellers can't control this directly, but you can encourage your buyer to instruct their solicitor immediately after the offer is accepted — not after their survey comes back.

Solicitor enquiries

Once searches come back, your buyer's solicitor will raise enquiries — written questions about the property. How quickly your solicitor responds, and how thorough your upfront paperwork is, determines whether this stage takes two weeks or two months. Vague or incomplete answers tend to generate further rounds of questions.

Survey results and renegotiation

A poor survey result doesn't have to derail a sale, but it needs careful handling. If significant defects are flagged, buyers may seek a price reduction or ask you to carry out remedial works. Having a trusted agent who can negotiate calmly on your behalf — and advise whether a request is reasonable — is genuinely valuable here. See our guide to the house selling process explained, stage by stage for more on how the survey fits into the wider timeline.

Chain problems

A sale chain is only as strong as its weakest link. If your buyer is selling a property that itself is in a chain, a problem anywhere along it can stall your sale. Chains of four or five properties are common in England, and coordinating exchange and completion across all of them is genuinely complex.

Personal agent vs high-street branch vs online agent: who keeps your sale moving?

The type of agent you choose has a material impact on how proactively your sale is managed once a buyer is found. Here's how the main options compare on the things that matter most when a sale is in progress:

A personal estate agent — someone self-employed, often backed by a network such as eXp UK — carries your file themselves from listing to completion. They have a direct financial interest in getting you to exchange, and no branch manager pulling them onto a new valuation when your buyer's solicitor goes quiet for a fortnight.

If you're not yet working with an agent, you can match with a personal estate agent, or browse personal estate agents in your area to find someone with genuine local knowledge.

How to manage your chain and keep buyers engaged

Keeping communication open with your buyer — through your agent — is one of the most underrated things a seller can do. Buyers who feel well-informed are far less likely to panic and withdraw. A few practical steps:

1. Ask your agent for a weekly update, even if it's just to confirm nothing has changed.
2. Set a realistic timeline at the outset so both sides know what to expect — surprises breed anxiety.
3. Be responsive yourself — when your solicitor asks you a question, answer it the same day if you can.
4. Consider a buyer's solicitor check — your agent can diplomatically find out whether the buyer's solicitor is on top of the file.
5. Agree a target exchange date with all parties once searches are back — it creates a focal point and applies gentle pressure.

What if searches or enquiries are genuinely stuck?

If searches are taking an unusually long time, it's worth asking your buyer's solicitor whether they have ordered indemnity insurance as an alternative. For some standard search risks, insurers will cover the buyer rather than waiting weeks for a council to respond. This is a legitimate and increasingly common approach, particularly for lower-risk properties.

If enquiries are stalling, ask your solicitor specifically which question is outstanding and why. Sometimes a file sits waiting for a document that you could supply in an afternoon — but nobody has thought to call you.

What should you do if a buyer threatens to withdraw?

Stay calm and find out the real reason. Buyers rarely withdraw without cause. The most common triggers are:

• Survey results they weren't expecting
• A change in their own financial position
• A feeling that the process is taking too long and no one is communicating
• A competing property they've found

An experienced agent can often recover a wobbling buyer through honest conversation and, where needed, a modest price adjustment that reflects genuine issues rather than buyer anxiety. If the sale does fall through, our step-by-step guide to selling your house in the UK covers what to do when you need to remarket.

A note on managing your own expectations

Even when you do everything right, some delays are outside your control — a slow local authority, a buyer's lender requesting additional information, or a problem in another part of the chain. Knowing what a normal timeline looks like helps you tell the difference between a process that is moving and one that is genuinely stuck.

For sellers listed with the right agent, most of this monitoring happens without you having to chase. That continuity — one person who knows your file, your buyer and your chain — is exactly what a personal estate agent provides, and it's genuinely difficult for a busy high-street branch to replicate consistently.
