Exchange and Completion UK, How long?

If you’re buying or selling a home in England or Wales, one of the biggest milestones is the exchange of contracts. From this point, the sale is legally binding — both buyer and seller commit to the deal, agree the completion date, and confirm what fixtures and fittings are included.

On completion day, the buyer’s funds are transferred, the seller’s solicitor confirms receipt, and ownership officially changes hands. It’s also when you hand over (or collect!) the keys.

But how long is there usually between exchange and completion — and what’s best for you?

Exchange and Completion UK, Allowing Sufficient Time

The typical gap is 1–2 weeks, but this can vary depending on the complexity of the chain.

• Mortgage lenders usually need at least 5 working days to release funds.

• Solicitors may request funds arrive the day before completion to prevent delays.

• For this reason, many sellers and buyers allow at least 7–10 days between exchange and completion.

This buffer helps avoid last-minute hiccups, especially when a mortgage is involved.

Speeding Up the Process

Good communication is key :

• Sellers should complete all property information forms in full.

• Conveyancers should keep an open line with buyers, lenders and surveyors.

• Buyers should ensure their mortgage instructions are checked and ready.

While it’s possible to exchange and complete on the same day, this comes with risks. Any hiccup with searches, mortgage funds or paperwork could cause the move to fall through.

Choosing the Best Day of the Week

Many people aim for a Friday completion, but this can create pressure — removal companies are in high demand and banks close for the weekend.

Instead, consider a mid-week completion (Tuesday or Wednesday). This often reduces stress, avoids higher moving costs, and gives you time to settle in before the weekend.

Final Thoughts

Every move is unique. While the standard gap between exchange and completion in the UK is around 1–2 weeks, the right timeframe depends on your chain, your lender, and how quickly solicitors can coordinate.
