Regulations to know
- The £7,500 Boiler Upgrade Scheme grant requires an MCS-certified installer — non-MCS quotes can't claim it
- Usually permitted development if the unit sits 1m+ from the boundary and meets noise limits
- Listed buildings and conservation areas need consent
Tips from the trade
- Insist on a room-by-room heat-loss calculation, not a quote off floor area
- Run it low and slow — heat pumps are cheapest left gently on, not blasted
