Heat load surveys and system design in Romford
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. No two rooms in Romford gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.

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.
The survey

On a survey in Romford the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
