      What is a heat loss calculation?

      A heat loss calculation determines how much heat your home loses through walls, windows, floors, and ceilings. It helps specify the right heating system size for your property.

      Why do I need one for my home?

      It ensures your heating system is properly sized, energy-efficient, and cost-effective, avoiding unnecessary bills and discomfort.

      Is this required before installing a new boiler or heat pump?

      Yes. Most modern systems, especially heat pumps, require an accurate heat loss report to meet performance and compliance standards.

      How long does it take to complete?

      Typically, a domestic heat loss survey takes a few hours, depending on your home's size. We’ll handle everything with minimal disruption.

      Will this help lower my energy bills?

      Absolutely. With a correctly sized and optimised system, you'll avoid energy waste and enjoy more consistent, cost-effective heating.
