Very prompt in supplying and explaining the quotation and doing the work. Dan, who did the installation, was first class and coped well with a busy house! He was very polite and efficient, and completed the work quickly and without fuss. All highly recommended.

What People Say

Same-day emergency call out to fix a broken valve on my central heating water tank in the loft that was alarmingly pouring water out of the overflow pipe into the back garden. Dan was our engineer and he was very thorough, friendly and efficient in fixing the problem.
