Wall-Lag (Wales) Ltd Reviews

Excellent, prompt and attentive service. All queries answered fully and well explained. Would certainly recommend to others.

Avoid this company at all costs. We spent around £30,000 with Wall Lag and were left with faulty equipment that they refuse to put right. They do not honour their warranties, they install equipment that is unsuitable for the property (a fact that has since been verified by the ombudsman), and they repeatedly try to demand additional money to fix their own mistakes. This is not just poor service – it’s deeply dishonest. When you pay this kind of money, you expect quality, accountability, and professionalism. Instead, you get cowboys who leave you worse off than when you started. I cannot stress this enough: do not trust Wall Lag. Do whatever you can to avoid them.

Great service from start to finish! The installers were polite and happy to help with any questions I had. Very happy with my solar install 😀

Had solar fitted 4 months ago, could not be happier. Surveyor explained installation progress, Lads fitting the panels were great and the electricians set everything up including an app on my phone. Highly Recommended

A completely professional company who met all deadlines with an eye to the detail on the quality of their work. Fully recommend them.

Great service, great communication and they help you make sustainable and renewable energy a part of your everyday life - what more could you want!

I had a great experience with Wall-Lag (Wales) Ltd. The team was professional, friendly, and always kept me updated from start to finish. They installed solar panels and explained everything clearly, making the whole process easy to understand. The work was done on time, very tidy, and I’m already seeing the benefits on my energy bills. I really appreciate their reliable service and would happily recommend them to anyone looking for renewable energy solutions.

My relatives recently had solar panels fitted and were very pleased with the service. The installation was smooth, the team was professional, and everything is working perfectly. Highly recommended!

I am very satisfied with the service of the company that repaired the heating and boiler in the apartment. Very fast and high quality, the guys were very polite, explained how everything works and didn't leave until they were sure that I learned how to use the boiler.

Fantastic service from start to finish on installing solar panels at my relatives property. The team attending were courteous and fully respected our property. Everything was explained fully to us and even finished on time too. Thanks so much for the install at our property. Price was very competitive also which is a bonus in the present climate. Thanks to all at Wall-lag who were involved.

From initial contact to the completion of our work Wall Lag have provided us with excellent service. Patrick listened to us as customers and our wants. He put in place a team of plumbers led by Jimmy, a man who knows heating systems inside out, who makes sure the work completed is to a high standard. Jimmy also shows his patience with a team of apprentices, allowing to build their careers. Added to this all the workmen (and Ellie!) were a delight to have in the house. They all have a determined work ethic, but are always willing for a quick chat and to answer my many, at times ridiculous, questions! We are impressed with the efficiency of installing a whole new ASHP heating system. Also, how they managed to start work so quickly for us when we were in desperate need! Wall Lag responded to any minor issues we had with solutions and have turned up to resolve minor running issues within 30 minutes of a call! I can’t fault the service, professionalism and end product. I would highly recommend giving Wall Lag a call if you are considering installing a new heating system and if possible ask for Jimmy to complete the work!

Had new radiotors and boiler fitted (housing tenant), the lads we very hard working, so polite, friendly and efficient. The plumbers and the electricians worked so well together and both were approachable with any questions I had etc… would definitely use in the future and recommend to friends. Lovely bunch of workers x
