Air conditioning installation in Crouch End

Two Crouch Ends, from an installation point of view

On paper N8 is one area. In practice it is two jobs, and which one you have determines almost everything about cost and timeline.

Intact houses. Victorian and Edwardian terraces and semis still in single occupation. You own the rear elevation, you make the decision, and a rear-mounted condenser on a heat-pump system has a reasonable route through the planning position. These are straightforward.

Converted flats. The same houses, split into two or three units. Now the external wall is shared or belongs to the freeholder, permitted development does not apply because it is a flat, and two separate permissions are needed before anyone touches anything.

A large share of Crouch End is the second kind. It is why I ask about tenure on the first call rather than at the survey.

If you are in a flat

The sequence that works:

1. Survey first, so there is a specific unit and a specific position to put to the freeholder. Vague requests get refused.
2. Submit a proper pack — position marked on a photograph or elevation, dimensions, weight, sound data, fixing method, my F-Gas registration and insurance.
3. Run the planning application in parallel, since flats have no permitted development rights.
4. Install once both are in hand. One to two days for a single room.

Allow four to ten weeks for the permissions and about a week for the work. Anyone promising a converted flat next week has not read your lease.

The back addition question

Most Victorian terraces here have the two-storey rear projection containing the kitchen and, above it, the bathroom or box room. It creates the same decision on almost every job:

Bracket the condenser on the addition’s flank wall, and it stays off the ground and out of the garden — but it is often within a metre of the boundary, which affects the permitted development position, and frequently sits below somebody’s bedroom window.

Put it at ground level in the garden, and it is easy to service and quieter upstairs — but it takes space from a garden that may already be small.

I will show you both at survey with the trade-offs spelled out. There is no universally right answer, only the right one for your layout and your neighbours.

Conservation area, in plain terms

Crouch End is one of Haringey’s 29 conservation areas. What that means on the ground is simple enough: nothing goes on the front, anything visible from the street will be scrutinised, and rear elevations are where the work happens.

That is rarely a problem. It just needs establishing before a quote is written rather than after.
