Common questions
My boiler's stopped working. How fast can you come?
Ring us. Emergencies get priority and we'll give you an honest time, not a window.
Do you service boilers?
Yes, annual servicing and landlord gas safety certificates.
Should I repair or replace?
Our honest default is repair. If the maths genuinely favours a new boiler we'll say so and show you why.
Are you Gas Safe registered?
Yes. [CONFIRM WITH CLIENT: registration number]
