    Commercial rate: £75+VAT per half hour, minimum 1-hour charge

    London boroughs

    Heat networks are concentrated in London’s newer blocks and regeneration estates, so most of our work is inside Greater London. We attend individual flats and plan block-wide programmes for managing agents and heat network operators.

    South East

    For commercial clients with schemes outside London, we support sites across the South East on a planned basis. Call to discuss the location and scope.
