"Vaillant Boiler Service"

I had a service today by Daniel. He was very thorough and sorted a system pressure fault which turned out to be an expansion vessel problem. The vessel was pressurized and all now working fine. I will use this company again.

"Mothers boiler service, replacement boiler for me"

Prompt, all persons dealt with, Gareth, Daniel & Lorenzo, polite, knowledgeable, guidance without pressure.
All work carried out to a high standard & followed up on the required work promptly.
Would definitely recommend and will use for annual servicing.

"Reliable service"

Made time to fit in a boiler check with very little warning. Have used them for years a always a reliable service.

"Awful customer service "

Awful customer service , the fitter was great and did a good job however half way through the job the owner txt to put another £90 on the bill for materials that cost £15. We had to ask for a call and then had an uncomfortable conversation and felt intimidated, we were clearly being ripped off purely because the fitter took longer than expected. Would not recommend avoid at all costs .

Annual boiler service - good communication, happy with service. Supporting documentation promptly received following the service.
