Recognised by the Guild of Master Heat Engineers
We're incredibly proud to be among the few engineers recognised as masters in our field — and to have been selected to help build the Guild of Master Heat Engineers' knowledge base. The Guild is a peer-assessed network of genuinely excellent heat-pump engineers: you're not in it because you paid a fee or passed an exam, but because the rest of the trade knows the work is good.
For you, that means a heat pump designed and installed to one of the highest standards in the country — by a local team that other master engineers respect.

Honest advice from Richard Smith
We're a family-run business, not a sales machine — and our managing director Richard Smith would rather give you a straight answer than a hard sell. Our guides tackle the questions we're asked most.
