TL;DR
In short
- Completion brings together the final payment and release of the keys; registration follows separately.
- England and Wales use exchange and completion. Scotland uses concluded missives and settlement, usually on the date of entry; Northern Ireland has its own conveyancing process.
- Follow your solicitor’s completion statement and payment instructions, accounting for any money already paid.
- Confirm buildings insurance arrangements before you become contractually committed, and wait for confirmation before collecting the keys.
- Agree a workable date and make a backup plan for delays. Friday is an option, but an unresolved problem may carry into the next working day.
Completion day is when the final payment and key release come together so that you can take possession of your new home. A clear plan helps you know what to expect while your solicitor handles the legal work. The procedure depends on where you are buying; ask your solicitor to confirm the contract, insurance and payment arrangements for your purchase.

What is completion?
In England and Wales, exchange of contracts creates the binding commitment to buy and sell. Completion is the later fulfilment of that agreement, although both stages can happen on the same day. Registration is a separate step after completion. The government’s home-buying guide explains these stages.
In Scotland, concluded missives create the binding contract. Settlement usually takes place on the agreed date of entry, when you get possession. Your solicitor handles the disposition and registration arrangements.
In Northern Ireland, exchange and completion are also distinct stages, but the legal process and registration system are Northern Irish. Follow your solicitor’s advice and the nidirect buying guide.
What happens on completion day?
The final payment
Your solicitor or conveyancer arranges the payment to the seller’s solicitor. The completion statement sets out the balance and costs, allowing for sums already paid. Your total contribution towards the purchase is not necessarily the same amount as an exchange deposit.
Where you have a mortgage, your solicitor arranges the lender’s advance under that lender’s conditions. Confirm how much you must send and when cleared funds are needed. There is no single early-payment or lender-drawdown timetable for every purchase.
Confirmation and keys
Wait for your solicitor to confirm completion and authorise the next steps. Keys are commonly collected from the estate agent or another agreed keyholder. Buyer and seller do not have to meet personally to complete: the Law Society’s completion-by-post procedure provides for completion without personal attendance.
Agree collection arrangements in advance, including gate keys, access fobs and garage remotes. A payment leaving your account does not by itself mean you can move in. There is no guaranteed key-release time for every transaction.

Tax and registration after completion
Your solicitor will normally handle the relevant return, tax payment and registration on your behalf. The buyer remains responsible for meeting applicable tax obligations; confirm what is included in your solicitor’s instructions. The regimes are:
- England and Northern Ireland: Stamp Duty Land Tax (SDLT).
- Wales: Land Transaction Tax (LTT).
- Scotland: Land and Buildings Transaction Tax (LBTT).
A return may be required even when no tax is payable. Ask your solicitor to confirm the applicable filing and payment deadline and provide confirmation afterwards.
Registration is with HM Land Registry in England and Wales, Registers of Scotland in Scotland, or the relevant Northern Irish registry through Land & Property Services. Do not assume the register has already been updated when you collect the keys.
What can delay completion?
Funds or outstanding requirements
Missing funds, lender requirements or unresolved legal work can prevent completion as planned. Stay available to your solicitor and ask for an update if the expected time passes. They can explain the contractual position, any costs and the next steps; neither the length of a delay nor its consequences is the same in every case.
A linked property chain
Linked sales and purchases often coordinate completion because one buyer needs proceeds from another sale. A delay can therefore affect several households. Ask how your purchase depends on the chain and discuss a backup plan for moving or overnight accommodation. Once contracts or missives are binding, withdrawing or failing to complete can have financial consequences; take advice before acting.

How to prepare for completion day
Check buildings insurance early
In England and Wales, buyers usually need buildings cover from exchange because contractual risk normally passes then. Check the contract and lender’s requirements with your solicitor. For a leasehold flat, an existing block policy may cover the building, so check before arranging duplicate cover.
In Scotland, insurance timing depends on the missives: Scottish government guidance advises cover from conclusion unless the missives say otherwise. In Northern Ireland, ask your solicitor when cover must begin under your contract and mortgage conditions. Buildings cover and contents cover serve different purposes; our home insurance information explains the options.
Follow the agreed payment instructions
Check the completion statement and the deadline for your own funds, fees and any tax money your solicitor needs to hold. Do not assume that all of your deposit first becomes due just before completion. Independently confirm bank details using a trusted contact number, especially if a message claims they have changed.
Plan the move and allow for uncertainty
Choose between moving yourself and booking a removal company according to your needs and budget. Check availability, access and waiting or cancellation charges. Keep essentials and your solicitor’s contact details accessible, and avoid relying on an exact key-collection time.
A new-build purchase may avoid an onward seller’s purchase, but it is not automatically simpler or free of chain dependencies. Construction progress can affect the date. Ask your solicitor how the contract sets completion and what happens if the home is delayed.

Use a moving-day checklist
- Confirm who will tell you completion has happened and where you will collect all keys and access devices.
- Check agreed fixtures and contents when you arrive and report discrepancies promptly.
- Photograph readings from any gas, electricity and water meters and contact the relevant suppliers.
- Update your address with the organisations you use and keep completion documents safely.
- Follow up with your solicitor for tax and registration confirmation when available.
Is Friday a good day to complete?
There is no best weekday for every purchase. Agree a date that works for the parties, solicitors, lender and moving arrangements. Friday may suit your plans, but an unresolved problem can carry into the next working day, particularly around bank holidays. An earlier weekday may leave more working days to resolve difficulties; compare actual removal availability and prices rather than assuming a saving.
Completions normally take place on working days. CHAPS settlement currently operates on weekdays, and banks and solicitors have their own cutoffs. Future payment-system proposals do not make weekend completion a normal current option. Confirm arrangements with your solicitor rather than relying on a universal time.
FAQ
Frequently asked questions
Is completion the same as exchange?
No. In England and Wales, exchange creates the binding contract and completion fulfils it; the stages can sometimes happen on the same day. Scotland uses concluded missives and settlement, while Northern Ireland has its own exchange and completion process.
When can I collect the keys?
Wait for confirmation that completion has taken place and keys can be released. Agree the keyholder and collection arrangements in advance; there is no guaranteed time for every purchase.
When do I send my deposit and remaining funds?
Follow your solicitor’s instructions and completion statement. An exchange deposit and your total contribution are different concepts; account for money already paid and confirm the deadline for the remaining cleared funds.
When should buildings insurance start?
Confirm the start date before you become contractually committed. In England and Wales it is usually exchange, subject to the contract and any block policy. Scotland depends on the missives; in Northern Ireland confirm the contract and lender’s requirements with your solicitor.
Should I avoid completing on a Friday?
Not necessarily. Agree a workable date and allow for the possibility that a Friday problem may carry into the next working day. Check moving arrangements and have a backup plan for delays.
