What is the cost to repair my boiler?

City Gas Services do not charge a call out fee between 9:00 am – 5:00 pm Monday to Friday. We will diagnose the problem and give you a quotation for parts and labour required to complete the repair. We do have a minimum charge of £70.00 Inc VAT. For Instance, if you required us to send an engineer out to re-pressurise your boiler or bleed your radiators this would incur a minimum charge which covers up to 1 hours of labour excluding parts to rectify the situation.

How much does it cost to Install a new boiler?

Every property and homeowner will have different requirements. It is impossible to give advice without carrying out a survey due to the amount of different variables. We offer a free survey and quotation for new boiler Installation at any time or day. Please contact us to book an appointment.

Are you Gas safe or CORGI registered?

All our engineers are Gas safe registered. The Gas Safe Register took over as the acting gas safety watchdog from CORGI.
