Completion day is the final element of the conveyancing process. You can exchange and complete within a matter of hours, but most people prefer to leave seven to 28 days for any final checks.
Once everything is in order, the balance of the purchase price can be paid. It can be a nervous wait on completion day because you need to wait for your mortgage lender to transfer the money to the seller's bank account. Ultimately, this can take a bit of time.
Once the funds land, the property is yours and you can collect the key and move in. Your conveyancer will then register ownership with the Land Registry and arrange for you to pay any stamp duty that’s owed.
