Wall-Lag (Wales) Ltd

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.

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.

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 pro

Had my underfloor heating and ashp fitted by wall lag, very professional and extremely polite workers 5STARS definitely

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
