No. There's no legal requirement for an owner-occupier to have a gas safety certificate to sell a house. The annual gas safety duty applies to landlords letting a property, not to selling one. That said, a recent boiler service record or a voluntary gas safety check can reassure buyers and help smooth the sale.

There's no legal requirement for an owner-occupier to hold a gas safety certificate in order to sell their home. The annual gas safety check is a landlord's duty for a property that's let, not something the law requires when you sell the house you live in.
Buyers and their solicitors often ask about the condition of the boiler and gas appliances. A recent boiler service record, or a voluntary gas safety check, gives them reassurance and can help a sale go smoothly. It isn't required, but it answers a common question up front.
Whether it's a service or a voluntary check, any gas work must be carried out by a Gas Safe registered engineer. This is general information, not conveyancing or legal advice for your particular sale.
