“Just like to say it’s been a pleasure getting to know all the site staff. Especially Rob and Leslie, two of the nicest people, polite and friendly and sweet souls, who work hard at their job. Thank you, it’s been a pleasure getting to know you all.”

Mrs I (Chesterfield)

“Miss H, of Baslow Drive has been in touch. She is very happy with the insulation which has made her house much warmer. She says: “The work done was quick and professional. I did have a problem – this was sorted very quickly by Beverly Lamb, who was considerate and couldn’t do enough to help. A great service. A job well done.” Can you pass on this praise please and thank everyone involved.”

Cllr. Sally Longford, Nottingham City Council

“The work carried out by SBS has transformed our home. It has provided a much needed facelift for the outside walls, which now look great, but it also means the house is a lot warmer – and we should save about £300 a year on our energy bills. Already, we can feel the difference and the condensation problem has been solved at a single stroke… Doing the roof at the same time as the insulation saved us literally thousands and we’re particularly grateful to your site manager; he did a great job of keeping us informed throughout the process and advising us about how we could make the most of our budget. All in all, we couldn’t be happier.”
