Office Fit-Out Merton

Office fit-out in Merton is mostly small-scale work. Merton protects office space in areas including Wimbledon town centre and the Garth Road industrial estate in Lower Morden, and beyond those you are more likely to be fitting out a suite above a shop or a small studio. The London Plan names Croydon, not Merton, as the strategic outer London office location. The typical job is a floor stripped back and re-planned for a new tenant, a professional office refreshed, or a studio fitted out, with the landlord's consent and building control in place.

For Merton, the construction part of an office fit-out is published at £70 to £120 per sq ft as a UK guide, and an all-in London office fit-out at £148 to £359 per sq ft (Oktra and Cushman and Wakefield, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Merton: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Where office space sits in Merton and what that means

Merton's office Article 4 direction shows where the council wants office space kept. Nationally, Class MA lets Class E space, offices included, become homes through prior approval, but Merton's direction requires planning permission instead in areas including Wimbledon town centre and the Garth Road industrial estate in Lower Morden. For a tenant this is context, not a consent you need: floors there are less likely to slip out of office use, so they come back to market for re-letting and refitting.

Outside those areas, an office above a shop or a small suite in Morden, Mitcham or Colliers Wood is more typical. London Plan Policy E1 asks boroughs to protect office clusters from office to residential permitted development. For a small business, a first floor suite over a parade shop brings its own constraints: one shared stair, an old electrical supply and a landlord who also lets the flat next door. We survey those points before quoting.

Cat A and Cat B fit-out for a Merton office

Cat A and Cat B describe who fits what in a Merton office. A Cat A finish is the landlord's base: ceilings, lighting, raised floor or trunking, heating and cooling and finished walls, left open plan. Cat B is the tenant's layer on top: partitions and glazed screens, meeting rooms, a tea point or kitchenette, extra small power, data routes for the client's IT supplier, and the decoration and signage that make it your office.

On a small Merton suite the line between the two is often blurred, because the landlord hands over a stripped shell. We start by agreeing with you what the landlord provides and what the lease says must be left at the end. Partitions are set out to suit existing ceiling grids and window mullions where possible, because moving lighting and sprinkler or smoke detector positions is where a small office budget grows.

Merton building control for a non-domestic office fit-out

An office fit-out that is building work goes to Merton building control on a full plans application, because the council's building notice route is only available for domestic projects. Merton runs its own building control service as part of LABC, and a full plans decision is issued within five weeks or, if agreed, a maximum of two months from the date first payment is received. The drawings are checked for fire and means of escape under Part B, access under Part M and lighting and services under Part L.

On a full plans approval in Merton, work may begin once a 48 hours notice of commencement has been given, and work started earlier is at your own risk. New partitions can lengthen escape routes or create inner rooms, so they are designed around the exits, not the other way round. Under the CDM Regulations a commercial client has duties of its own, including allowing enough time and resources, and we explain those before the programme is fixed.

Working in occupied Merton buildings and at lease end

In a shared Merton office building, the other tenants keep working through your fit-out. Merton expects noisy work to stay within weekday and Saturday morning hours, with Sundays and bank holidays normally quiet, so drilling and strip out happen in the day and quieter tasks run later with the landlord's agreement. Materials kept on the highway need a licence, and the standard commercial building materials licence in Merton runs for 28 days.

Dilapidations are the other end of the lease. When a Merton office lease ends, the landlord may ask for partitions to be removed and the space reinstated to its original condition. We record the space before your fit-out, keep the landlord's licence drawings with the handover pack and, when the time comes, price the strip back against the schedule of dilapidations the landlord's surveyor issues. Reinstatement often needs the same building control and hours as the fit-out, so it deserves its own programme.

• Small power to desks, floor boxes and perimeter trunking
• Metal stud office partitions boarded both sides
• Tea points and kitchenettes on the existing risers
