    Having just moved in to a new house I didn't know how it worked. The electric shower stopped working so I called SC Duncan to find a solution. Colin came round quickly and told me exactly what was wrong. Unfortunately for them I didn't need any work in the end but I'll definitely use them next I need something doing.

    My first stop for any plumbing issues. Absolutely brilliant team. Have been really helpful and supportive. Clean and tidy workers. Did run late on the day as held up at a previous job, but made sure I was aware - so not left hanging wondering if they were going to arrive.

    James and his team are fantastic, I highly recommend them. They were friendly, flexible and accommodating with my specific requirements. Also very fairly priced. They did a great job, and everything is working and signed off as it should be.

    I had a new boiler installed, I cannot fault this company. Dealing with her staff was an absolute pleasure and they went out of their way to accommodate me. The workmanship was beyond excellent, we did not leave any mess and I am really satisfied with the job that they have done. I will definitely be using this company again
