Covering South Ruislip
Our survey diary covers South Ruislip, including HA4, UB5. The same team covers Ruislip (1 mile), Northolt (2 miles), Hayes (Hillingdon) (3 miles), Pinner (3 miles), all within easy reach.
Bushey, in Hertfordshire, is roughly 6 miles from South Ruislip and also on our list. In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.
Included in a typical project

- Back door and a hard-wearing floor
- Built-in storage or space ready for your units

Planning rules that apply in South Ruislip
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific South Ruislip address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
