Sam responded promptly to my air con enquiry and even visited me at short notice to firm up the scope. We were fitted in quickly, and Dave managed the job well, with the team carrying out a nice tidy install. Would definitely use again in the future and I will certainly recommend to others.

After struggling with underfloor heating that had been left in a broken state by a previous company, my dad endured almost no heating throughout the winter. It was a frustrating and uncomfortable situation until Sam from Newton Electrical and Mechanical came to the rescue. Sam was incredibly professional and knowledgeable. He quickly identified the issues, including faulty wiring and broken pumps, and thoroughly cleaned the entire system. Within just two weeks, the system was completely fixed and working perfectly. The level of care, expertise, and efficiency from Newton Electrical and Mechanical was outstanding. I can’t thank them enough for the difference they made. I’d highly recommend them to anyone needing reliable and skilled professionals for their heating or electrical needs.

We used Newton Electrical and Mechanical for all of our electrical and plumbing work in a large home renovation project and I would thoroughly recommend them. Sam Dave and colleagues have all been knowledgable, reliable, trustworthy and communicative and take pride in completing work to a high standard, a pleasure to work with. As with any large project dealing with multiple trades, some things didn’t quite go to plan, but I found that any issues that Newton Electrical could help with were resolved quickly and without fuss. It’s very hard to find tradespeople you can trust, but if you’re reading this, congrats- you’ve just found some.
