Design and duty calculation
Room-by-room heat gains, fresh-air rates to Building Regulations Part F, and a coil selection with the psychrometrics done rather than assumed. You get the state points, not just a kilowatt figure.
Services
Four things, and we do all four ourselves.
There is no design partner and no labour-only subcontract. The engineer who calculated the duty is the one who signs the commissioning sheet, which is the only arrangement under which anyone can be held to a number.

Install
Air-handling plant, chilled water, VRF and air-source heat pumps, ductwork to DW/144, and the electrical and controls work that goes with them. Our own fitters, no labour-only subcontract.
03
Commissioning
Air volumes proportioned and recorded to CIBSE Commissioning Code A, water systems balanced, and every coil checked against its design condition on the day. Signed sheets, not a tick box.
04
Service and breakdown
Planned maintenance on a fixed visit rate, statutory F-Gas leak checks logged, and a four-hour response for contract sites. Most breakdowns we attend are condensate, filters or controls.

Install prices are quoted per job after a survey. Anyone quoting an install without having been in the building is quoting a guess.
