Building control here sits with the Southern Building Control Partnership, which inspects drainage before it is covered and tests it for water tightness afterwards. We coordinate that. Fully insured, with free no obligation quotations.
For Leatherhead, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Surrey work generally runs below that.

Drainage in a bathroom is inspected twice
The Southern Building Control Partnership lists separate drainage inspections, one before the drains are covered and another after covering, when they are tested for water tightness. Moving a soil connection, a shower waste or a whole bathroom to a different room puts new drainage into the structure. Both stages have to be called.
That decides the order of the job. Waste runs and falls are set and inspected before floors, screeds and tiling close over them. We make the application and book the visits, so the plumbing, the tiling and the inspection sit on one programme with one point of contact.
Housing in Leatherhead
For Leatherhead the Council Tax list gives about 6,970 homes; by type 44% flats and 56% houses, by age 69% post-war, 16% interwar and 14% older than 1919. A detached house in Leatherhead can add a soil stack for an en suite, and 19% of homes here are detached.
A bathroom inside a listed building is not outside the consent regime
Listed building consent covers internal alterations that affect the special interest of the building, and Leatherhead's listed entries include ordinary street addresses. Bridge Street carries eight separate entries on the National Heritage List for England. 1, 1A and 1B North Street were listed Grade II on 2 April 1970.
Grade matters to how a case is handled. Leatherhead has four Grade II* listed buildings, the Church of St Mary and St Nicholas, the Running Horse public house, Thorncroft Manor and Rowhurst, and there is no Grade I here. Everything else listed is Grade II. We build to consents that are already in place rather than advising on them, and we say plainly where something needs an application first.
If the bathroom work changes the outside
Where a new window, a new vent or an external soil pipe is part of the job, the planning side can come into play. A householder pre-application enquiry to Mole Valley District Council must include a red edge site location plan at 1:1250, photographs and proposal drawings. That is the route to a written view before anything is ordered.
Purely internal work does not raise it. The waste runs change, the drains are inspected before and after covering, and nothing outside moves. We tell you which of the two you are in before we quote, free and with no obligation.

Why Leatherhead Homeowners Choose GS Renovation
A bathroom job in Leatherhead can run into listed building consent before it runs into a tiler. Bridge Street alone carries eight entries on the National Heritage List for England, and consent covers internal alterations that affect a building's special interest. We establish what your address is subject to before we price the work, build to consents that are already in place, and coordinate the drainage inspections the Southern Building Control Partnership requires. We are fully insured and quotations are free and carry no obligation.

FAQ
Frequently Asked Questions about Bathroom Renovation Leatherhead
What should I budget for bathroom renovation in Leatherhead?
Budget for bathroom renovation in Leatherhead as three amounts inside £6,000 to £20,000 or more (London-derived): the structural element, the finishing trades and the approvals. Approvals belong in the budget wherever the job includes Part P certification for any new circuit or work in the bath and shower zones. GS Renovation lays the KT22 quotation out the same way, so each element can be checked or deferred.
The wet room needs joists trimmed. Is that inspected?
Yes. The Southern Building Control Partnership lists a structural elements inspection to be called before structural timbers, steelwork or concrete are covered up, and altered joists are structural timbers. The framing is therefore seen before boarding, screed and tanking go over it. The engineer we appoint specifies any trimmer or support, and we build to that. The visit is booked into the programme rather than chased afterwards.
How does the drainage inspection fit around the tiling?
It goes before the floor closes, not after. The Southern Building Control Partnership takes calls on 0330 024 9355 or at theteam@southernbcp.co.uk, Monday to Friday, 9am to 5pm, and the pre-covering drainage stage has to happen while the runs are still open. We set that date against the plumbing programme, so the tiling follows the inspection instead of waiting on it.
A new soil pipe will run up an outside wall. Is that a planning matter?
It can be, where the elevation sits in the conservation area. An Article 4 direction is in force in part of Leatherhead's, and Mole Valley District Council describes its directions as protecting features that contribute to the special interest of streets. That can bring a pipe on a street facing wall into an application. Ring the planning team on 01306 885001 before anything is fixed to the wall.
Does the building control application have to be in before the bathroom is stripped out?
Yes. The application goes in before the work starts, and it goes to the Southern Building Control Partnership rather than to Mole Valley District Council. The inspection stages then begin while the work is open. Making the application at the start means the pre-covering drainage visit can be called at the right moment rather than after a new floor has gone down. We make it and hold the reference.
