“Just had Scott fit our new boiler and I can’t praise him enough — professional, tidy, explained clearly what he was doing and cleaned up afterwards. From Scott the fitter to the bubbly, friendly girls in the office, I’d recommend RJ Martindale to everyone.”
“Excellent service at an excellent price from Ryan and his team for 5 years now. My mother-in-law has just had a new boiler thanks to them and started the Homecare plan, which is so much cheaper than British Gas. We have Homecare too and wish we’d done it sooner.”
“We wanted an aircon unit in our main bedroom and it was done quickly, without issue and without any mess — just so tidy. Dan was superb. A few other jobs done at the same time to a very high standard. Would give 6 stars if I could.”
“What a fabulous team. The office staff are so accommodating and pleasant and the workmanship is excellent. Nothing is too much trouble, no short cuts. I’m changing my long-standing home care agreement with British Gas to Martindale’s because I’m so impressed.”
“New boiler installed. Dan was excellent — used floor protection and footwear covers, respected the property and cleaned up any mess. I’d definitely recommend RJ Martindale for your heating and plumbing needs. Very friendly.”

“A Wi-Fi Bosch air con install in our conservatory. Cannot fault the installers, Daniel & Aaron — a neat job with absolutely no mess, and personable chaps who are a credit to the company. We chose Martindales on the back of reviews and their Which? accreditation.”
