      Bespoke heating system design for your property

      Every home heats differently. Before any installation begins, LGS engineers assess your property’s size, insulation level and hot water demand to specify the right system. For heat pump projects, our design process calculates the correct flow temperatures to maximise efficiency, matching the approach that our customers consistently highlight in reviews.

      Accurate design prevents oversized equipment, reduces running costs and ensures your installation meets current Part L building regulations.
