Building in Welling
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.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
So when we survey a Welling property for a new bathroom, the first step is working out how it was built and what has been changed since.
Do you need permission in Welling?
The notes below cover England, which is where Welling sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
From survey to handover
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.
Quote in writing
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Dates and permissions
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.
On site to finish
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.
How we work
Common questions
Do I need planning permission in Welling?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Welling 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.
How much will a new bathroom cost in Welling?
As a guide, expect to pay £6,500–£15,500 including VAT for a new bathroom in Welling. That range is adjusted for London, which runs about 30% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
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.
How much does a new bathroom cost?
A typical family bathroom costs £6,500–£15,500 supplied and fitted, including tiling, a new suite, shower, lighting and an extractor fan. Shower rooms and simple en-suites cost a little less, while wet rooms, standalone baths and large-format tiles cost more. Moving the toilet or replacing rotten floorboards adds to the total. We confirm a fixed price for the agreed specification after the survey.
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.
