Common questions

How long does a service take?

A standard annual boiler service takes around 30–45 minutes. Access to the boiler and a clear space around it helps us work quickly.

Does servicing keep my warranty valid?

Yes. Most manufacturers require an annual service by a Gas Safe registered engineer to keep the guarantee valid. We give you a written record each time.

What’s the difference between a service and a Gas Safety check?

A service checks the boiler is running efficiently and safely. A Gas Safety check (CP12) is the certificate landlords are legally required to hold for every gas appliance in a rented property. We can do both in one visit.

Can you do certificates for a portfolio?

Yes. We look after single flats and whole portfolios, book around your tenants, and track renewal dates so you never lapse.
