Boiler Replacement - Great local company!
My 12 year old boiler was on its last legs and after much debate I decided to replace it rather than continue to have the same things repaired over and over. I wanted to use a local company, and support my local community rather than use one of the big national companies. I am so glad I chose SC Duncan Heating and Plumbing. The quote they provided was quick, value for money and detailed and I was able to schedule the work a few days later. The new boiler was fitted by Colin and he did a fantastic job. He was quick and efficient, tidy and was great at explaining what was being done and why. I feel very confident in recommending this company to others and will be using them again in the future.

I had been without hot water for some time before I found SC Duncan in Stevenage High Street. Several people had looked at it but could not find the fault. I had various members of the team working on the problem and they persevered until it was fixed. This included several calls to the house, emails and phone calls. The team are polite and efficient and called when they said they would. I thoroughly recommend this firm.
Very helpful plumber

Excellent service.
My boiler stopped working so we called SC Duncan Heating Plumbing Electrical in the morning. They had someone come out that afternoon, he did a full troubleshoot as the issue wasn’t usual to the error code on the boiler. Within two hours he had found the problem and fixed it. Very efficient and professional. Would definitely use them again.
