“Reliable, trustworthy and a very knowledgeable heating engineer. Stewart identified the problem, replaced pipework where a blockage had occurred and fitted a magnetic filter. Very fair with pricing. Highly recommended!”

Trustpilot review
“Stewart has serviced our Vaillant boiler for years. When a flexible pipe split and water was gushing, he came out straight away despite being off ill and fixed it. Totally reliable, prompt and excellent service.”
