    We recently had a battery-only installation from M J Wallace, it's been a perfect addition to our house so we can now charge during the off peak hours to use cheap electric during the day. The team were excellent and we would highly recommend this company to others.

    The solar installation with 10 panels , 2 batteries and inverters, including one in case the grid has a powder cut and will let us use our own battery supply and an EV charger were all fitted between 9 am and 2pm when the 6 man team had all left.The system is working really well and although more pricey than some installers, the quality of the installation and equipment is worth it.

Mike was really helpful, patiently answering all my questions and responding quickly to all emails. The lads (Alex, Key and Ollie) who fitted the units working tirelessly and diligently. Overall really happy with the work and would happily recommend MJ Wallace.

    Mike recently completed an installation for one of our customers and did an excellent job from start to finish. The feedback from the customer was extremely positive, and from our side Mike was professional, knowledgeable and straightforward to work with throughout. It’s always important to us that customers receive the same level of service during installation that we expect from our own team, and Mike absolutely delivered that. We’d have no hesitation recommending him and would be very happy to work with him again.

    Outstanding service from M J Wallace Limited. Having gone through a solar panel installation once before with another company, the level of professionalism and efficiency here was far superior. They supplied and fitted 12 solar panels, a Fox Cloud battery and inverter, and a Hypervolt car charger. Communication was brilliant throughout, the work was completed remarkably fast, and the site was left clean and tidy. Exceptional team.

    Of the 3 different solar companies we contacted for a quote, Mike was the only person who actually came out to look at the job properly and took the time to understand exactly what we wanted rather than just sending over a generic quote. He gave us a design built around our needs and took the time to explain everything so we actually understood what we were getting and why. We ended up booking a complete solar installation with battery storage, full backup capabilities and an EV charger. We couldn’t be happier with the finished installation. From the initial visit right through to completion, it was clear that Mike and the team really know what they’re talking about. Everything was explained properly, our requirements were listened to, and the quality of the finished job is excellent. We honestly couldn’t recommend M J Wallace highly enough. A great company to deal with from start to finish. Thank you very much to Mike and the whole team!
