What happens on completion day in the UK?

Completion day is when the money moves and the keys change hands. Here is exactly what happens, who does what, and what to expect — including why keys sometimes arrive at 3pm rather than 9am.

Completion day is the culmination of weeks or months of legal process. For buyers, it often feels anticlimactic at first — you are waiting for a phone call — and then suddenly, intensely real when you are handed the keys.

What happens on completion day

Completion is primarily a money movement exercise managed by solicitors. Your solicitor draws down your mortgage funds, combines them with the deposit, and transfers the total purchase price to the seller's solicitor. Once cleared funds are confirmed, keys are released.

In a chain, every transaction must complete before keys are released at any point. A chain of four transactions means four sets of solicitors and four confirmations. This is why keys in a chain are almost never available before noon.

Typical timeline

  • Morning: Solicitor chases mortgage lender for funds release.
  • Late morning to early afternoon: Money moves up the chain.
  • Midday to 2pm: Most completions confirm during this window. Delays are common.
  • Key release: You receive a phone call from your solicitor, then the estate agent.

What to do on completion day

Do not book the removal van for 8am. Keep your phone charged. Take meter readings immediately. Change the locks on day one. Do a walkthrough before the removal van unloads.

After completion

Your solicitor registers the ownership change with HM Land Registry and pays stamp duty. This takes weeks or months but does not affect your ownership, which is established from completion.
