GS Renovation carries out whole-house renovations across Mitcham, bringing tired interwar terraces and semis and post-war houses in CR4 up to modern standards under one roof. We rewire, replumb, replaster and reconfigure dated layouts, sequencing every trade so your refurbishment runs as one coordinated project.

In Mitcham, 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 Mitcham: 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 Mitcham and bathroom renovation in Mitcham. In the 53% of homes here that are houses, moving the kitchen usually means opening up the back of the ground floor, which is structural work.

Full refurbishments of Mitcham homes

A Mitcham house that has not been touched in decades usually needs the lot: old wiring replaced, plumbing renewed, walls replastered and a layout that suited another era reworked for how families use a house today. We manage all of it in the right order, so first fix electrics and plumbing go in before plastering, and structural changes like opening up the reception rooms happen before the finishes. One team, one programme, one point of contact.

Interwar houses often keep worthwhile original features, picture rails, panelled doors, decorative plaster and cast fireplaces, and where you want them kept we restore rather than strip them out. Where a wall is load-bearing we bring in a structural engineer and the necessary steel, all signed off by Merton Council building control, so the character stays but the fabric, insulation and services are brought right up to date.

Housing in Mitcham

The stock in Mitcham runs to roughly 10,560 dwellings, 46% of them flats and 53% houses, built 10% before 1919, 38% between 1919 and 1939 and 51% after 1945. 40% of homes here are terraced; a mid-terrace in Mitcham has no side access, so strip-out goes through the hall.

Renovating a Mitcham house to let to sharers needs planning first

Merton has removed permitted development rights across the whole borough for converting homes (Use Class C3) to small houses in multiple occupation. For a landlord renovating a Mitcham house, that changes the order of work. If the finished house will be let room by room to unrelated sharers, planning permission comes before the layout is designed, because turning the front reception into a bedroom assumes a use that has not yet been granted. Apply first, then draw the fire separation, the kitchen size and the bathrooms to suit the permission.

For an owner-occupier the paperwork trail matters more. A whole-house renovation in Mitcham produces several separate sign-offs: Merton building control for any structural work, electrical certificates for new circuits, and the gas engineer's record for a moved boiler. Merton building control issues a completion certificate when the work is finished and advises keeping it because it will be needed to sell the property. Start one folder on the first day and add each certificate as each trade finishes, rather than chasing them years later when a buyer's solicitor asks.

Sequencing trades across your Mitcham house

The value in a whole-house renovation is the sequencing, and that is exactly where a piecemeal, trade-by-trade approach falls down. On a Mitcham refurbishment we set out a clear order: strip out, structural work and steelwork first, then first fix services, plastering, second fix, and finally kitchens, bathrooms and decoration. Because one team holds the programme, the plasterer is not waiting on an electrician who has moved to another job.

Living in CR4 while the work happens is easier when the disruption is planned rather than open-ended. We phase the work so key rooms come back into use in a sensible order, keep the site tidy in an occupied home, and coordinate the kitchen and bathroom installs to land at the right point. The outcome is a house that has been renovated as a whole, not a collection of jobs that never quite line up.

FAQ

Frequently Asked Questions about Home Renovation Mitcham

Are there hidden costs with home renovation in Mitcham?

Every extra cost on home renovation in Mitcham needs your written agreement, and the foreseeable ones are already priced within £40,000 to £150,000 or more (indicative). Work in post-war housing around CR4 occasionally reveals something behind plaster; when it does, GS Renovation stops, costs it and waits for your decision. The sequence of work stays fixed: the rewire and replumb finish before any plaster goes on.

Can you renovate my whole Mitcham house in one project?

Yes, that is exactly how we prefer to work. We take a Mitcham house from strip-out through rewiring, replumbing, replastering and any structural steel, then on to kitchen, bathroom and decoration, all sequenced by one team. Internal renovation does not need planning permission, though new circuits are notifiable under Part P and are certified by a registered electrician or notified to building control. A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Merton Council, and doing it without consent is a criminal offence.

Should the rewire in a Mitcham house happen before plastering?

Yes. New cables and back boxes go in at first fix, alongside any new pipework, and then the plasterer covers them. Doing it the other way means chasing new plaster. New circuits are notifiable under Part P and a registered electrician certifies them, which a buyer's solicitor will ask for later.

Which rooms should a Mitcham house renovation tackle first?

The dusty, structural and service-heavy work first: any wall removal, then the rewire and heating, then kitchen and bathroom, with bedrooms and decoration last. Finishing a bedroom before the rewire risks cable chases through new plaster, so the order follows the trades rather than the rooms.

Which parts of a Mitcham renovation need building control?

Structural work, new circuits under Part P, new bathrooms and kitchens with extraction under Part F, drainage changes under Part H, and replacing or upgrading a thermal element under Part L. Merton building control or the relevant certifying installer signs these off. Decoration, flooring and like-for-like replacement generally do not.

When should the boiler be chosen in a Mitcham house renovation?

Before first fix. A combi suits one bathroom, while a house adding an en-suite may need a cylinder system for flow at two outlets at once. That decision fixes pipe sizes and routes, which are laid before plastering, so changing it later means opening walls again.

Does a pre-1919 Mitcham house need a different renovation plan from a post-war one?

The order of trades is similar, but the risks are not. 10% of Mitcham homes were built before 1919 and 51% after 1945. An older solid-walled house is renovated around damp, lime plaster and timber decay, so breathable plasters and paints matter. A post-war house is renovated around its services, concrete floors and replacement windows. Confirm the age before choosing plaster, insulation or flooring, because the wrong material can trap moisture in an old wall.

Is Merton's pre-application advice worth using for a Mitcham renovation?

It can be where the renovation changes the outside, such as a new porch, altered front windows or a rear addition. Merton's Category D householder pre-application advice includes a 15 minute virtual meeting only. That is enough for one or two focused questions. Send clear drawings and photographs of the Mitcham house in advance and list the questions, so the meeting is spent on answers rather than on describing the property.

What should a Mitcham leaseholder settle before renovating a whole flat?

The shared parts. 46% of homes in Mitcham are flats, and a full flat renovation reaches into the rest of the building. A rewire may run back to a meter in a communal cupboard, the soil stack may be shared with the flat above, and new hard flooring can carry sound to the flat below. Get the freeholder's licence for the whole scope, check whether the lease requires carpet or an acoustic underlay, and agree access to shared risers before strip-out.
