Covering Windsor
Our coverage around Windsor (SL4) also includes Slough (2 miles to the north) and Egham.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What does bathroom installation involve?
Bathroom installation covers stripping out the old suite, altering plumbing and wiring, waterproofing, tiling, and fitting the new bath, shower, toilet, basin and heated towel rail. We also build new en-suites and shower rooms in lofts and extensions.
- Design and layout
- Plumbing and waste alterations
- Extractor fan, lighting and heated towel rail

Planning and building rules in Windsor
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.
Bathroom refits do not need planning permission.
What should I think about before starting?
- Wet rooms need a fall to the drain and full waterproofing.
- Large-format tiles need flat walls, which may mean re-boarding.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
