The exchange of contracts marks a legally binding milestone in the UK home buying process. Both parties sign identical contracts, which solicitors or conveyancers then formally exchange. Upon exchange, the completion date is set, and the buyer is typically required to pay a deposit, often amounting to 10% of the purchase price. Withdrawal after this stage could result in legal and financial penalties for the party at fault.

On the agreed completion date, the remaining funds are transferred from the buyer’s solicitor to the seller’s solicitor. Upon confirmation of receipt, the property’s legal ownership formally transfers to the buyer. At this point, the estate agent may release the keys, and the buyer can take possession of the property. The process is coordinated to ensure both legal and practical transfer occur smoothly.
Following completion, the buyer’s solicitor is responsible for submitting the required documents to HM Land Registry. Registration involves updating the property title to reflect the new owner’s details. This step may take several weeks to finalise, depending on Land Registry processing times and the volume of transactions. The buyer may also be required to pay applicable Stamp Duty Land Tax (SDLT), depending on the property price and relevant exemptions or reliefs.
New owners are advised to review post-completion steps, such as informing utility suppliers, updating council tax registration, and arranging suitable insurance coverage. While not legally mandated, thorough attention to these administrative details can support a seamless transition into the new property. Transitioning successfully typically involves both solicitor support and proactive management by the buyer.
