Bedroom and loft air conditioning in St Helens
For bedrooms in St Helens, we place the outdoor unit at the back of the house, away from neighbours' windows. Milder summers in the North West mean designing for winter comfort as much as for a heatwave.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
