Frequently Asked Questions
Does every rented home in Isleworth need a gas safety certificate, even without a licence?
Yes, rented homes with landlord gas appliances need an annual safety check and record under regulation 36, whether licensed or not. A property’s licensing status does not remove that duty. The check covers every landlord gas appliance and flue, and existing tenants must receive the record within 28 days.
Can I renew my Isleworth gas safety certificate early without losing the expiry date?
Yes, regulation 36A allows the check to take place in the two months before the existing deadline while preserving that deadline for the next annual check. This is an early renewal window, not a grace period after expiry. Provide your current record when arranging the appointment.

Yes, we cover Osterley as well as Isleworth in TW7. Give us the full address, details of every landlord gas appliance and a tenant contact for access when booking. Our phone line is open 24 hours a day, 7 days a week.
