Choose your route

Start with the type of outcome you need

01Target a difficult room

One-room comfort

Useful for lofts, conservatories and workspaces with a clear design brief.

02Room-by-room design

Whole-home planning

Heat distribution and indoor-unit positions need more than a simple floor-area rule.

03Summer comfort first

Cooling-led use

Evaluate heating as an additional capability rather than an unsupported saving claim.

Compare on evidence

Four checks that protect your budget

Treat grant eligibility, planning constraints and claimed energy savings separately. A sound decision begins with the building, existing heating and intended operating pattern.

Seasonal efficiencyCompare SCOP and SEER on the same climate and test basis.

Cold-weather outputCheck manufacturer capacity data at lower outdoor temperatures.

Air distributionDoorways alone may not move conditioned air evenly between rooms.

Professional designEquipment sizing and refrigerant installation require competent assessment.
