Home Renovation Welling

GS Renovation carries out whole-house refurbishments across Welling, breathing new life into the 1930s semi-detached and interwar houses that fill DA16. These homes were solidly built but many still have dated wiring, cramped layouts and tired services. We manage the structure, trades and finishes together under one team.

In Welling, a full house refurbishment typically costs £40,000 to £150,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Welling: we carry the structure, services and finishes as one contract.

The two rooms that cost the most have their own pages, with prices: kitchen renovation in Welling and bathroom renovation in Welling. In the 78% of homes here that are houses, moving the kitchen usually means opening up the back of the ground floor, which is structural work.

Whole-house refurbishment across Welling

A full renovation of a Welling interwar semi usually starts below the surface, with a rewire to bring the electrics up to current standards and fresh plumbing to replace decades-old pipework. We then replaster throughout, which renews the tired walls and ceilings these houses often carry. Running all of this as one coordinated programme means the disruption is concentrated and the trades follow each other in the right order rather than tripping over one another.

Reconfiguring the dated layout is where these homes gain the most. The original 1930s plan often boxes the kitchen into a small rear room and separates the reception rooms, so we open things up, sometimes with a steel beam, to suit how families in DA16 actually live now. Where original features such as picture rails, panelled doors or fireplaces survive, we restore and keep them so the house retains its interwar character.

For the Welling statistical area the Council Tax list gives about 4,020 homes; by type 21% flats and 78% houses, by age 18% post-war, 76% interwar and 5% older than 1919. 56% of homes here are semi-detached; a semi in Welling usually has side access.

Paperwork a Welling renovation should settle before work starts

A whole-house renovation in Welling often starts with a house that has already been altered, and the first job is finding out what was signed off. A wall opened, a garage converted or a rear room added without a certificate can often be regularised, and Bexley adds VAT to its building control prices except on regularisation charges. It is far easier to regularise an old alteration while the floors are up and the ceilings are open than after the new plaster is on.

Fees are the second item. Bexley Council's building control fees were adjusted from 20 April 2026 to reflect the up-to-date cost of processing and determining applications, so a renovation budget that carried a fee line from an earlier quote needs it checked. Once the building control work on a Welling renovation is finished, the notice of completion must reach Bexley not more than five days later, and the certificate that follows is the document a buyer's solicitor will want.

Sequencing the work in your Welling home

The value of a single team on a Welling refurbishment is the sequencing. Structural work and any steel go in first, then first-fix electrics and plumbing, then plaster, then the kitchen and bathrooms, then second-fix and decoration. We plan this order from the outset so that nothing finished gets disturbed by work that should have come earlier, which is a common and costly failing when trades are booked piecemeal by the homeowner.

We know how these interwar houses behave, from the solid or cavity walls to the suspended timber ground floors and the chimney stacks in the shared party wall. That familiarity means fewer surprises once floors are lifted and walls are opened. Whether you are living in the house through the works or renovating an empty DA16 property before moving in, we set a realistic programme and keep the site tidy and safe throughout.

• Kitchen and bathroom design, supply and installation
• Plastering, flooring, painting and decorating
• Room by room programme so you can stay in your home
