What Happens on Completion Day? 2026 UK Seller's Guide

By Lisa Hayes · 29 August 2026

Completion day is the day legal ownership of your house transfers to the buyer. Your solicitor receives the balance of the purchase price, confirms it, and only then releases the keys — usually somewhere between late morning and mid-afternoon. You need to be moved out and the property empty by the time that money lands, because from that moment the house is not yours.

It sounds simple. For most sellers it is. But completion day is also the point where months of paperwork are compressed into a few hours that depend on bank transfers, a chain of other people's solicitors, and a removals van that may or may not be running late. Knowing exactly what happens, in what order, and what your rights are if it goes wrong is the difference between a mildly stressful Friday and a genuinely awful one.

What actually happens on completion day when you're the seller?

Four things have to happen, in this order.

First, your buyer's solicitor sends the completion money by CHAPS — the same-day payment system UK conveyancers use for property. Second, your solicitor's client account receives it and reconciles it against the completion statement. Third, your solicitor telephones or emails the buyer's solicitor to confirm completion has taken place and undertakes to send the signed transfer deed (form TR1) and title documents. Fourth, your solicitor rings the estate agent and authorises release of the keys.

Everything else you might picture — handshakes, a symbolic key handover on the doorstep, signing something in front of a notary — doesn't happen. Nearly every residential sale in England and Wales completes by post and telephone under the Law Society's Code for Completion by Post, which lets the buyer's solicitor act as the seller's solicitor's agent for the mechanics of the day. You will almost certainly never meet your buyer.

Behind the scenes your solicitor is also doing three jobs that matter to you: redeeming your mortgage, paying the estate agent, and sending you the balance. More on the money below.

What time does completion happen — and why does 2pm matter?

There is no fixed legal time for completion, but the contract sets a practical deadline. Condition 6.1.2 of the Standard Conditions of Sale (5th edition, 2018 revision), which is used in the overwhelming majority of residential sales, says that if the money due on completion is received after 2pm, completion is treated as taking place on the next working day for the purposes of compensation and apportionments.

That single line has real consequences. It means a buyer whose funds arrive at 3.15pm hasn't just inconvenienced you — they may technically be a day late, and you may be entitled to compensation for that day. It also means solicitors treat 2pm as a hard target and start getting twitchy at noon.

CHAPS itself is not usually the bottleneck. Most bank cut-offs sit between 4.25pm and 5.30pm, and a payment sent in the morning typically settles within a couple of hours. The delay is almost always human: a solicitor waiting on funds from the transaction below, a lender releasing mortgage advance late, or a file that only got picked up after the 10am post.

Completion day hour by hour: what does the timeline look like?

One practical point that catches people out: leave the keys with the estate agent the day before, or first thing in the morning. Agents hold them and release on your solicitor's word. If you're selling privately or without an agent, agree in writing beforehand exactly where the keys will be and who releases them — a key safe with a code released by your solicitor works well.

When do you get your money, and how much will actually land?

You get the money on completion day, but not the full sale price. Your solicitor receives the gross figure and pays everything off the top before sending you the balance. If completion happens comfortably before 2pm, the money usually reaches your account the same afternoon. If it lands at 3pm, expect it the next working day — most firms won't send a CHAPS out after their own cut-off.

Here's roughly what comes off, on a £320,000 sale with a £145,000 mortgage:

Ask for the completion statement before the day, not on it. A good solicitor sends it a week out. If yours hasn't, chase — it's the only document that tells you what you're actually walking away with, and it's the only chance to query a fee before it's deducted. We cover the full picture in our guide to the true cost of selling a house in the UK, and the timing side in when you get the money when you sell your house.

If you're within a fixed-rate period, the early repayment charge can be the single largest line on that statement. Get the redemption figure in writing from your lender early; they're valid for a limited window and they change.

Who releases the keys, and can you refuse to hand them over?

Your solicitor releases the keys. Not you, not the agent on their own initiative, and certainly not the buyer's persistence.

Until the money is in your solicitor's client account, you still legally own the house. If a buyer turns up at 11am with a van and asks nicely, the answer is no. It happens more than you'd think, and it is the single most avoidable disaster on completion day: if you hand over keys and the funds then fail, you have someone living in a house they haven't paid for, and getting them out is a possession claim, not a phone call.

The reverse is also true. Once your solicitor confirms completion, you must be out. Staying "just until the removals van comes back at six" is a breach of contract, and the buyer can charge you for it. If you genuinely can't be out on the day, that needs to be agreed in writing, with a licence to occupy, before exchange — not sprung on anyone at 1pm.

What do you have to leave behind — and what can you take?

Whatever you said on the TA10 Fittings and Contents Form. That form is contractual, and it is the source of a surprising number of last-minute rows.

If you ticked "included" against the curtains, the curtains stay. If you ticked "excluded" against the garden shed, you can take it — but you're expected to make good, and ripping a shed off a concrete base at 8am on completion day is asking for a complaint. Anything you didn't mention at all defaults to the general rule: fixtures (attached to the property) pass with it, fittings (freestanding) don't.

Practical checklist for the last hour:

• Every key, labelled: front, back, French doors, windows, garage, shed, key safe code, gate padlock.
• Manuals and warranties: boiler, alarm, solar inverter, heat pump, appliances you're leaving.
• Meter readings for gas, electricity and water, photographed with a timestamp, sent to your suppliers the same day.
• Alarm codes, bin collection day, the quirk about the stopcock. A one-page note left on the worktop costs you five minutes and buys enormous goodwill.
• The property properly empty. "Empty" means the loft, the garage, the side return and the bin store too. Leaving rubbish for the buyer to remove is a legitimate claim against you.

Take a photo of every room once cleared. If a dispute comes later about damage or removed items, dated photographs settle it in about thirty seconds.

What if completion is delayed on the day?

Late completions are common and usually harmless. Most resolve within a couple of hours. The problem is that you rarely find out early, and the removals firm is on the clock.

• 2pmthe contractual cut-off for same-day completion
• 7.75%current contract rate (4% over Barclays base)
• 10working days in a notice to complete
• 10%of the price the buyer's deposit is at risk

If the buyer is late, you are entitled to compensation under condition 7.3 of the Standard Conditions: interest on the balance of the purchase price at the contract rate for each day of delay. The contract rate is the Law Society's interest rate, which is 4% above Barclays Bank's base rate. With base rate at 3.75% in August 2026, that's 7.75% a year — on a £288,000 balance, roughly £61 a day. Not life-changing, but it's yours, and your solicitor should claim it rather than quietly waive it. Plenty do waive it. Ask.

You can also claim your actual losses if they're foreseeable and you can evidence them: an extra night's removals storage, a hotel, the fee your own seller charges you for being late up the chain. Keep the receipts.

What is a notice to complete, and what happens if the buyer never completes?

If the buyer hasn't completed by the end of the contractual completion day, you can serve a notice to complete. Under condition 6.8 of the Standard Conditions, this makes time of the essence and gives the buyer 10 working days (excluding the day of service) to complete.

During that window the buyer must pay the interest that's accruing. If they still fail to complete at the end of it, you can rescind the contract, and condition 7.5 lets you keep the 10% deposit, resell the property, and claim damages for any shortfall on the resale plus your wasted costs.

Two honest caveats. One: if the buyer paid a reduced deposit — 5% is common, and some contracts allow less — you can require the balance of the full 10% as part of the notice, but recovering it from someone who's already run out of money is optimistic. Two: serving a notice to complete is a decision with consequences. It commits you to a path. If your buyer is 48 hours from funds because their lender fumbled a release, serving notice may cost you more in a collapsed chain than waiting a day. Take the advice, then decide.

How does completion work in a chain?

Money moves up, keys move down, and nobody moves until the person below them has.

In a chain of four — first-time buyer, you, your seller, their seller — the first-time buyer's mortgage advance and deposit start the sequence. Their solicitor sends to your solicitor. Your solicitor, seeing the funds, then sends the money for your purchase to your seller's solicitor, and so on. Each hop is a separate CHAPS payment with its own reconciliation, and each one realistically takes 20 to 60 minutes when everyone is at their desk.

What that means in practice:

1. The bottom of the chain gets keys first and the top gets them last, sometimes by three or four hours.
2. A single late link delays everyone above it. There is no way to leapfrog.
3. Book removals with a flexible afternoon slot, not a fixed 1pm handover.
4. If you're both selling and buying, ask your solicitor to confirm whether they can complete your purchase on the strength of your sale funds arriving — most can, but they need the sale money first.

Longer chains fail more often, and they fail late. It's the single strongest argument for choosing a chain-free buyer even at a slightly lower price, which is worth weighing up alongside what your house is actually worth.

Should you exchange and complete on the same day?

Some sales exchange and complete simultaneously — often auction purchases, cash buyers, or a chain-free sale where everyone just wants it done. It's legal and it's increasingly common. It also removes the safety gap that exchange normally gives you.

My view: a gap of one to two weeks between exchange and completion is the sweet spot for a normal sale. It's long enough to book a decent removals firm and short enough that the buyer's mortgage offer and survey stay fresh. Same-day is right when speed is the whole point and you're dealing with a genuine cash buyer — and only when your solicitor has already seen proof of funds. If you want the difference between the two milestones spelled out, read exchange of contracts vs completion.

What if you're selling and buying on the same day?

This is the normal British experience and it is genuinely stressful, because you are homeless for a few hours by design.

The mechanics: your solicitor receives your sale money, uses it (plus your new mortgage advance and any savings you've already sent them) to complete your purchase, and pays the SDLT on your new home within 14 days. You physically move out of a house you no longer own into a house you don't yet own, in a van, on a motorway.

Three things make it survivable.

1. Send your solicitor every penny they need at least three working days before. Not the day before. Bank fraud checks and payment limits stop more completions than solicitors do. If you're moving more than your daily online limit, arrange it with your bank a week out.
2. Pack an overnight bag and a "first night" box that travels in your car, not the van. Kettle, mugs, phone chargers, loo roll, medication, the kids' and the dog's things, a torch. If completion slips to 4pm you will be unpacking in the dark.
3. Give the removals firm both addresses, both agents' numbers and your solicitor's direct line. Then let them talk to each other while you deal with the actual move.

If your buyer's side is the weak link and your purchase depends on it, ask your solicitor about a short-term bridging option before the day, not during it — the guide to bridging loans to break a property chain sets out when it's worth the cost and when it isn't.

What still goes wrong at the last minute?

The failure modes are predictable, which is why they're preventable.

• Mortgage funds released late. The buyer's lender needs several working days' notice. If the buyer's solicitor only requested funds the day before, you'll be waiting until afternoon.
• Redemption figure wrong or out of date. Your lender's figure is valid to a stated date. If completion slips past it, your solicitor needs a fresh one, and that can take hours.
• Bank fraud holds. Large CHAPS payments get flagged. This is now one of the most common causes of a two-hour delay.
• Property not empty. The buyer's agent does a final inspection. Rubbish in the garage stops key release.
• Someone below in the chain simply isn't ready. Nothing you can do except keep your removals informed.
• Last-minute price renegotiation. Rare after exchange, because the contract is binding — but it happens before it. If your buyer tries it, our guide on gazundering tells you how to respond.

Worth knowing: the wider market has been getting slower, not faster. Connells Group reported that the average time from agreeing a sale to exchanging contracts in Great Britain hit 104 days in April 2026, up from 76 days in 2019, with 17% of homes taking more than six months to exchange. Completion day itself hasn't got harder. Everything before it has.

How do you make completion day go smoothly?

A short, unglamorous list that works.

1. Don't complete on a Friday if you can avoid it. It's the busiest day for conveyancers, banks and removals firms, and if anything slips you're stuck until Monday with no legal owner able to fix it over the weekend. Tuesday and Wednesday are quieter and cheaper for removals.
2. Get the completion statement a week early and query anything you don't recognise.
3. Confirm the redemption figure and any early repayment charge in writing from your lender.
4. Book removals for the morning, with an afternoon contingency. Ask what they charge for waiting time; the honest firms will tell you upfront.
5. Drop all keys at the agent the day before. Count them and get a receipt.
6. Take meter readings and photos of every empty room before you lock up.
7. Keep buildings insurance running until midnight on completion day, not from the moment you leave.
8. Set up Royal Mail redirection at least five working days beforehand, and tell your lender, council, GP, DVLA and bank the new address.
9. Have your solicitor's direct number and your agent's mobile in your phone, and don't ring them every twenty minutes. One call at noon is enough.

If you want the whole journey mapped rather than just the last day of it, the conveyancing process explained walks through every stage, and our property jargon guide decodes the terms your solicitor will use without thinking.

How is completion different if you sell to a cash buyer or quick-sale company?

It's shorter, quieter and far less likely to slip — because most of what goes wrong on completion day is caused by mortgage lenders and chains, and a genuine cash buyer has neither.

With a funded cash house buyer, there's no mortgage advance to release, no valuation condition, and no chain below you sending money up. Completion typically runs from 7 to 28 days after instruction, and you often get to name the date — which matters enormously if you're managing a probate deadline, a repossession hearing, or a purchase you can't afford to lose.

The honest trade-off: you'll be offered below the open-market figure, typically somewhere between 75% and 85% of it depending on the property and the buyer. That's the price of certainty and speed, and it's a reasonable trade in some situations and a poor one in others. What is never reasonable is a buyer who agrees a price, then reduces it a week before completion because of something a survey "found". That's a well-known tactic, and the answer is to compare several offers before you commit — see how below-market offers actually work and how the main buying companies compare.

Before you accept any quick-sale offer, ask for three things in writing: proof of funds, whether they are buying directly or passing you to a third party, and whether they are a member of The Property Ombudsman redress scheme. A company that won't answer all three isn't going to be reliable on completion day either.

Completion day, in one paragraph

Be out, be empty, leave the keys with the agent the day before, and let your solicitor tell you when it's done. The money arrives, the mortgage is redeemed, the deed goes off to the buyer's solicitor and the house stops being yours somewhere around lunchtime. If it's late, it's usually the chain, and you can charge interest for it. If it's very late, there's a notice to complete and a 10% deposit standing behind you.

If your priority is a completion date you can actually rely on, the sensible first step is to see what a chain-free sale would look like alongside an open-market one. Compare offers here — it's free, there's no obligation, and knowing both numbers is the only way to judge whether certainty is worth what it costs you.
