Our Testimonials

I highly recommend Phil and his team at Beneficial Insulation. They Insulated my two rental properties. I found Phil friendly, helpful and prompt. As well as being reasonably priced and doing a good tidy job, they also went beyond expectations by installing extra insulation for a sub standard eqc fletchers repair, outside of Phil's original quote, at no additional cost – Excellent Customer Service.


We are really pleased with the work Phil's team did for us. Not only is the price competitive but the service couldn't be faulted. Phil was excellent at keeping me informed about the work and the team that came to install were friendly, polite and efficient (they even helped me unload the shopping from the car). Our home feels so much warmer and retains the heat from the sun in the day. I would highly recommend these guys.


Outstanding honesty and workmanship. We were so thrilled, Phil arrived with his team at arranged time. When finished Phil insisted that we check to see if we were happy with the workmanship before payment was made. Could not fault his professionalism in all aspects. Would highly recommend Phil and his team to anyone. We need more of these tradesmen, honest, dependable, hassle free, no hidden costs and an excellent job. Well done! Could not have asked for better.
