Heat load surveys and system design in Flint
Every Flint quote starts with a room-by-room survey rather than a guess from floor area. Mild North Wales summers mean heat pump heating is usually the headline benefit.
For self-builds and extensions in Flint, a standalone design pack can go straight to your builder. Our Clwyd coverage takes in Flint, about 15 miles from Wrexham. Coverage includes CH6.

Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
The survey
On a survey in Flint 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
