I chose this company to vacuum and insulate my cavity wall because of the good reviews, and they more than delivered! Honest advice, good communication, and excellent professionals. We even contacted them afterward and received photos for the subsidy. Highly recommended!

After much deliberation, we finally decided to insulate our cavity wall. We already had uPVC window frames with triple glazing, so we were skeptical about the benefits. After they visited, we finally decided to have it done, and we definitely don't regret it! They were a very friendly and professional company. The guys who came to our house worked very neatly, accurately, and were surprisingly quick. We've really noticed the difference; there's an alley next to our house, and we had this wall fully insulated. The thermostat no longer goes above 19°C to get warm, and we only used 95m³ of gas in December to heat the house daily. We are extremely satisfied. If you're considering having your cavity wall insulated, I would definitely recommend this company!
