Frequently asked questions
Quick answers about our services, coverage and how to book.
How do I know if my boiler needs repairing or replacing?
A one-off fault can usually be repaired. Repeated breakdowns, rising running costs, an ageing boiler, parts that are no longer available or a major component failure usually point to replacement. Our engineers diagnose the fault and give you a clear written recommendation with the options.
How often should I service my boiler?
Boilers are generally serviced once a year, and commercial plant or catering gas equipment may need more frequent checks depending on use and manufacturer guidance. We can set up a planned preventative maintenance programme so servicing never gets missed.
Do you install new boilers and heating systems?
Yes. We install commercial boilers, heating systems and plant room equipment, and we also fit boilers and heating for homes and landlords.
