House Refurbishment Welling

House refurbishment in Welling is, in the main, the renewal of an interwar house. The VOA's Welling statistical area, one of several covering DA16, dates 76% of its homes to the years 1919 to 1939, with 5% older and 18% built after 1945, and counts 78% of all homes as houses. We renew the whole fabric without re-planning the rooms: wiring, pipework, heating, plaster, floors, stairs and joinery, then decoration. The work runs on a Welling street under Bexley's rules for working hours, skips and scaffold.

For Welling, published UK figures put a three-bed house refurbishment at £43,530 to £110,350, and London houses usually cost more, with a London architect allowing £1,800 to £2,200 per square metre before VAT (Checkatrade and Bradley Van Der Straeten Architects, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Welling: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

What an interwar Welling house hides behind its plaster

An interwar Welling house is built in brick, and its services have been renewed in pieces for close to a century. With 76% of homes here dating from 1919 to 1939, the house you are refurbishing is likely one of them, and 58% of homes are semi-detached or detached. Behind the plaster you may find earlier rewires joined into older circuits, iron or lead spurs left on the water main, and suspended timber ground floors with airbricks that have been blocked by paths or render.

Textured ceilings, old floor tiles and flue pipes from this period can contain asbestos, so any suspect material is sampled before the strip out disturbs it. The 5% of Welling homes built before 1919 add lath and plaster ceilings and lime mortar, which we repair with lime rather than cover in gypsum. The 18% built after 1945 tend to bring different problems: cavity walls, early central heating and flat roofs over porches and garages that have reached the end of their life.

Housing in Welling

Of the 4,020 homes the valuation list records in the Welling statistical area, 5% were built before 1919, 76% between the wars and 18% since 1945; 21% are flats and 78% are houses. 56% of homes here are semi-detached; a semi in Welling has a single party wall, so one neighbour hears the chasing.

The order of works in a Welling house refurbishment

A Welling house refurbishment runs in five stages: strip out, first fix, plaster, second fix and finish. The strip out opens the floors and walls so the registered electrician we bring in can assess the circuits and the plumber can trace every pipe back to the stopcock. First fix puts the new cables, pipes and heating runs in while the walls are bare. Plaster follows, and it must dry before joinery, floor finishes and the kitchen go in.

Some of that work is notifiable. New heating, replacement windows and renewing a large part of a wall, floor or roof bring Part L insulation standards into play, and Bexley building control must hear about notifiable work at least 48 hours before it starts. The exception is work a competent person scheme installer self-certifies, as registered window fitters and electricians usually do. When the work is done, the completion notice has to reach Bexley within five days. The completion certificate that follows is what a buyer's solicitor or lender will ask to see when you sell the Welling house.

Skips, bay suspensions and scaffold outside a Welling house

The street outside a Welling house sets the logistics of the job. Bexley's construction hours are 8am to 6pm on weekdays and 8am to 1pm on Saturday, with Sundays and bank holidays off, so a refurbishment week is five and a half days long and the loud stages are planned into daylight hours. A skip permit from Bexley covers one skip for up to 14 days and needs at least two working days' notice, so we book it before the strip out rather than on the day.

Where the semi has a drive, the skip can often sit off the road and no permit is needed. Where it does not, a parking bay suspension is charged by the day or by the week, and we size the booking to the demolition stage. Roof, gutter and chimney stack repairs need scaffold, and where it stands on the pavement a Bexley scaffold or hoarding licence covers a 3 month period, so the roofwork is grouped to finish inside one licence. A chimney stack shared with the attached house is a party structure, so its repair needs a party wall notice under the Party Wall Act, and the owner serves the notice.

Refurbishing a Welling house you live in, let or are selling

An empty Welling house is refurbished fastest, because every trade can work in every room and the stages run back to back. If you are living in the house, we phase it floor by floor or room by room, keep one bathroom and a kitchen area working, and seal each work zone with dust sheeting and a zip door. That adds weeks to the programme, and we agree the phases in writing before the start date so you know which rooms you lose and when.

Executors and sellers often want a shorter scope: safe electrics, working heating, sound plaster and clean decoration, ready for a valuer. Landlords re-letting a whole Welling house have an extra test. GOV.UK says that since 1 April 2018 a private landlord may not let a domestic property on a new tenancy with an EPC rating of F or G, unless an exemption applies. Since 1 April 2020 the E minimum has covered existing tenancies too. Insulation and heating upgrades therefore go in while the rooms are empty.

• Whole-house rewires, certified at completion by a registered electrician
• Decoration throughout the house, woodwork and ceilings included
• Loft insulation topped up while the tank space is cleared
