  • Pack up possessions in property, ready to move out.
  • Organise Royal Mail postal redirection for the date of completion.
  • Release keys to selling agent or the buyer once confirmed by the seller's solicitor.

  • Take utility meter readings and give to providers.

Solicitor final checks before exchange

The buyer's solicitor will review the source of funds, contracts, title documents and property searches. They will also raise the legal enquiries and write a report on the title of the property.

The seller's solicitor will draft contracts and respond to enquiries. If needed, they will carry out the necessary investigations to try and satisfy those enquiries.

How long can the gap be between exchange and completion?

The standard time between exchange and completion is usually 2 weeks. The issue is when you're buying a new build property, as you will be exchanging contracts within 28 days of reserving it, and it can take months to completion.

The timeline will be agreed upon by the parties involved in the transaction on a case-by-case basis. You will find that the shortest time between exchange and completion can be the day of completion or 3 days before, although this might not always be suited. The maximum time between exchange and completion can be a couple of months. We explain the timeline in more detail in our article - How Long Between Exchange and Completion?.

Can things go wrong between exchange and completion?

Once contracts are exchanged, you are legally bound to complete the transaction, which means you can't pull out of the transaction after this stage without incurring financial costs. However, some issues may still arise in the process.

  • Completion day can be delayed
  • Property defects may be discovered
  • Mortgage issues, such as the mortgage offer being withdrwan

What if the buyer wants access before completion?

This poses risks to both sides, read our guide before giving the buyer access before completion.
