What Our Clients Say

  • "A very good service from start to finish. We'd recommend Energy Wrap to anybody looking to get their loft insulated."

    Angus & Julie

  • "Our new SuperFOIL loft insulation was installed quick and at a great price. We're already beginning to feel the benefits 2 months in!

    Andy, Nottinghamshire

  • "My parents were constantly complaining of damp issues . EWL surveyed their home and found the cavity wall insulation to be the culprit. Within 2 weeks from quotating, they extracted the old and replaced with new. Couldn't fault them."

    Rahul, Leicester

  • "A few years ago I saddely rushed into Spray Foam insulation, which has since become uncompliant. With the original company no-longer, Energy Wrap were on hand to carefully remove the bad insulation, and install brand new state-of-the-art foil. My loft now looks like a space ship!"
