What a Gas Safety covers in London
The UK's largest private rented sector, with one of the highest landlord densities in Europe. Landlords letting property here must hold a valid Gas Safety certificate before a new tenancy begins, and must renew it at least every 12 months.
Postcode areas typically covered include E, EC, N, NW, SE, SW, W, WC. Engineers serving London may charge a small premium for properties inside congestion or low-emission zones where parking and travel times add cost.
A standard Gas Safety inspection takes between thirty and ninety minutes depending on the size and age of the property. The Gas Safe registered engineer checks each gas appliance for tightness, ventilation, flue performance and safety device operation, then records the results on the Landlord Gas Safety Record (CP12). Any unsafe appliance must be isolated immediately and remedied before the property can continue to be let.
