16 ReviewsNew Gas Boiler Installation in Jarrow
Punctual, professional, courteous and knowledgeable. Quotes promised and delivered on time. Installation only scheduled at this point in time.
Keith — Jarrow
New Gas Boiler Installation in Sunderland
May not have been the cheapest, but definitely not the dearest.
Anthony was comprehensive and informative with his site survey and quotation.
Installation of the new boiler was carried out promptly cleanly and with all my technical queries well answered.
If the ongoing servicing and maintenance is of an equivalent standard I'll have nothing to complain about!
David — Sunderland
New Gas Boiler Installation in Newcastle Upon Tyne
The boiler was replaced as quoted, they worked practically non-stop. When the work was complete we were shown how to use it and a follow up call was made. I would recommend the company without hesitation. Phil Cockerill.

New Gas Boiler Installation in Bishop Auckland
A first rate, customer focused approach. They were able to answer all my questions and some I had not thought to ask. An honest appraisal of the work that needs doing. They are great value for money and very professional. Their work is of the highest standard and fully guaranteed. I recommend them to all considering having heating and pluming work carried out.

New Gas Boiler Installation in Newcastle Upon Tyne
Anthony just the man for the job. Recommended to replace diverter valve when others suggested new boiler. On strip down, diverter head needed to be replaced too, price as originally quoted. Wouldn’t have found him without “ boiler guide”.
