Why is the Completion Date Changing? 

Until you exchange contracts, any date you’ve been told is just a target. It’s common for these proposed dates to shift as the chain moves toward the finish line. However, once you exchange, that date becomes a legal deadline. 

Why target dates shift before exchange 

The most common reasons for a slipping target date are the chain tug-of-war (finding a single day that works for multiple families and their removal companies is the ultimate logistical puzzle), mortgage drawing times (many lenders now require a minimum of 5-6 working days between receiving the request for funds via the Certificate of Title and the actual completion date, if an exchange happens late on a Friday, the earliest completion date might already be a week away), and last-minute admin (missing certificates for things like EV chargers or solar panel warranties can cause a solicitor to pause until the paperwork is complete).

What happens if completion is delayed after exchange? 

This is rare but serious. If the date is fixed in the contract and one party cannot complete on that day, they’re in breach of contract. If you’re the buyer and you’re late, you’ll likely have to pay daily interest (usually at a rate of 4% above the base rate) on the remaining purchase price to the seller. 

The ready party’s solicitor will serve a formal Notice to Complete. This typically gives the defaulting party ten working days to finish the deal. If they fail to meet this new deadline, the innocent party can pull out, and if it’s the buyer at fault, they lose their 10% deposit. 

Because transactions are linked, a 24-hour delay at the bottom of a chain can cost thousands in storage fees and emergency accommodation for everyone above. 

The golden rule 

Do not book your final removal van, cancel your internet, or give notice on a rental property until your solicitor has called you to confirm that contracts have officially exchanged.
