Heat load surveys and system design in Alnwick
Every Alnwick quote starts with a room-by-room survey rather than a guess from floor area. Cooler North East summers mean cooling is mostly needed in lofts, conservatories and rooms with large windows.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
Surveys in Alnwick cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
