What is a house-to-flat conversion?

We assess the house against the council’s policies on flat sizes, parking, bins and cycle storage before any design work, then design layouts to the space standards your council uses. On site the critical work is fire separation, sound insulation between floors, separate services and meters, and protected escape routes.

How is a house-to-flat conversion approved in Surrey?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

Dividing a house into flats always needs planning permission in England. Councils assess flat sizes (many use the nationally described space standard), parking, bins, cycle storage and the effect on family housing supply.

What should Surrey homeowners check first?

Each flat needs its own utilities and metering.
Mortgage lenders and freehold arrangements need early legal advice.
