Energy Survey provide Energy Specification Reports for older building upgrades, both domestic and commercial. At Energy Survey we always recommend a call out before any work has begun on your property (you may have purchased an older house or commercial unit in reasonably poor condition). We can advise on what elements (floors, walls, roofs, etc) should be insulated, and to what levels. We can advise on the boiler condition/replacement or which heating controls will work best. We also advise on what renewable technology (Solar PV, Solar Thermal, Heat pump, etc) will work best and what size the system should be. In our experience, it is a common mistake for building owners to install inappropriate technologies/systems on building refurbishments. Give us a call, we can help.
