Request an appointmentHow often should my boiler be serviced?
Follow your boiler manufacturer’s servicing schedule, which is usually annual. Check your warranty or guarantee terms too, as keeping up with the required servicing may be a condition of cover.
Is a service the same as a repair?
No. A service is routine maintenance and checking; a repair deals with a fault. If your boiler is not working properly, mention this when requesting a visit so the appointment can be planned accordingly.
How much will the visit cost?
Boiler and system servicing is £95 including VAT, including pressure vessels on heating and hot-water systems such as Megaflo. Fault assessment and repair charges are confirmed separately before the visit; any further repair work is agreed with you first.
Will a repair be completed on the first visit?
That depends on the fault and whether suitable parts are available. Some issues need a further visit. We’ll explain what is needed and discuss the arrangements with you.
Do I have to replace a faulty boiler?
Not necessarily. An assessment helps establish whether a repair is appropriate. If replacement is worth considering, we’ll explain why and discuss the options. You can also read about our boiler installation service.
Can I book without calling?
Yes. Request a date and arrival window on our booking page. Morning appointments are 8am–12pm and afternoon appointments are 12pm–4pm. Your request becomes a confirmed appointment once you receive an approval email.
