Gas / Heating engineer

Arrived when they said they would, kept in touch and explained what needed to be done. The boiler replacement was done quickly, they cleaned up and were polite. Very happy with the job completed.

Extremely helpful, professional and communicative. Visited property and went through job requirements in detail. Converted an old gravity-fed conventional boiler system to a combi boiler system, did an excellent job, continued working until the water could be re-connected on the first day so that we wouldn't be without overnight, left the property in a tidy manner and were very thoughtful of having minimal impact on our home (e.g. protecting carpets, new pipe placements). Very pleased and would hire again.

Nick was absolutely fantastic. He went above and beyond to provide my partner and I an overview of the fault and the steps needed to resolve it. He was accommodating, methodical and understanding.

Keith was very polite and friendly. He arrived at the property at the appointed time and provided ideas that could help free space by installing the boiler in a different location. Awaiting a quote so we can move forward with the job.
