Local housing and a new bathroom
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
That mix of housing shapes how we approach a new bathroom in Wallington: the age and construction of your home affect the materials, the method and, in the end, the price.
Permissions for a new bathroom in Wallington
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Wallington comes under England, covered below, and we raise any questions with the council before your quote is finalised.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new bathroom, and photograph or measure anything the quote needs to reflect.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Finish and handover
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.
Why homeowners choose us
Questions about a new bathroom in Wallington
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
Is a wet room right for my home?
A wet room is a fully waterproofed room with a shower area that drains through the floor, with no tray or step. It suits accessible bathrooms and modern designs, and makes cleaning easy. It needs a floor with enough depth for a gentle fall to the drain, and careful tanking of the whole room. Timber floors often need strengthening. We check suitability at the survey.
Do I need planning permission in Wallington?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Wallington is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Will I have to go without a bathroom?
If it is your only bathroom, you will usually be without a shower or bath for most of the fitting time. We aim to keep the toilet working overnight wherever possible, refitting it temporarily at the end of each day during strip-out and first fix. If you have a second bathroom or downstairs toilet, the disruption is much easier. We plan the sequence with you before starting.
