Office fit-out in New Barnet is small scale. New Barnet is a District centre in the London Plan rather than an office location, so the office work that arises is in upper floors above shops, small suites and professional offices around East Barnet Road and New Barnet station. We fit out those spaces for a business moving in or reconfiguring: strip out, partitions, ceilings, lighting and small power, a tea point and WCs, ready for the day the lease starts.
For New Barnet, 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 New Barnet: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

The office space New Barnet actually has
The London Plan classifies Mill Hill, New Barnet and North Finchley in Barnet as District centres, and names Croydon town centre as the strategic outer London office location. New Barnet is therefore a local centre with offices in it, not an office district. The work that arises is a first floor suite for an accountant or a lettings agency, a studio behind a shop, or a small practice on East Barnet Road.
That scale shapes the fit-out. A suite of a few rooms can often be turned round in a short programme once the landlord has consented, but it sits in an old building with a shared stair, a single entrance and a flat or another business next door. We survey the stair, the incoming supplies and the fire escape route first, because in a converted upper floor those set the limits on how many people can use the office.
Cat A, Cat B and what a New Barnet suite needs
Cat A is the landlord's base finish: a clean shell with ceilings, lighting, heating, power to the floor and WCs. Cat B is the tenant's layout on top: partitions, meeting rooms, a tea point, furniture power and branding. In a small New Barnet suite the two often merge, because the landlord hands over a stripped floor and the tenant pays for everything from the ceiling down. We agree early which items the landlord provides and which you pay for.
A typical scope for a suite near New Barnet station starts with strip out of the last tenant's partitions. Then come new stud or glazed partitions, a suspended or plastered ceiling with LED panels, small power and floor boxes, a kitchenette and the WCs brought up to date. We coordinate the data cabling routes with your IT supplier, who terminates and tests the network. We also leave spare containment so later changes do not mean opening the ceiling again.
Building regulations and CDM duties for a New Barnet office
An office fit-out in New Barnet is non-domestic work, and Barnet Council or a registered building control approver checks any notifiable part of it. New partitions change the escape routes, so Part B fire and means of escape is usually the main item: travel distances, fire doors, emergency lighting and alarms. Part M covers access and an accessible WC where one is needed, and Part L covers new lighting and heating controls.
As a commercial client you carry duties of your own under the CDM Regulations, including appointing a competent contractor and allowing enough time and information for the work to be done safely. Where we are the only contractor, we still prepare the construction phase plan; where more than one contractor is involved, you appoint a principal designer and a principal contractor. Where the building stays occupied, noisy work such as cutting and drilling is grouped into agreed slots within the council's permitted hours, and quiet work such as decoration can run after hours.
Landlord services and the end of a New Barnet lease
Class MA allows a building in Class E, which includes offices, to change to homes through prior approval, so some upper floor offices in New Barnet may become flats over time. For a tenant the useful questions sit closer to hand. In a shared building the landlord usually keeps the fire alarm, the heating and the incoming supply, recovered through the service charge. New detectors, extra circuits from the landlord's board or a moved call point therefore need its contractor or its written approval, and we agree those tie-ins before the layout is fixed.
The other question is what happens when you leave. Many leases require the tenant to remove its alterations and hand the space back as it was let, and the licence for alterations records what you added. In a New Barnet suite, reinstatement clauses decide how much of your fit-out may have to come out again. We photograph and record the space before strip out and keep the as-built drawings, so the dilapidations discussion starts from evidence rather than memory.

FAQ
Frequently Asked Questions about Office Fit-Out New Barnet
How much does an office fit-out cost in New Barnet?
Published guides put the construction part of an office fit-out at £70 to £120 per square foot (Oktra, 2026) and an all-in London fit-out at £148 to £359 per square foot (Cushman and Wakefield, 2026). The survey and your layout fix the scope, and the quote itemises strip-out, partitions, ceilings, lighting, power and making good.
Is there much office space to fit out in New Barnet?
There is some, but it is small. New Barnet is a District centre in the London Plan, which names Croydon town centre as the strategic outer London office location. Office space here is upper floors, small suites and professional offices, so the fit-outs are compact jobs rather than whole floors of a tower.
What is the difference between Cat A and Cat B fit-out?
Cat A is the landlord's base build: ceilings, lighting, heating, power and WCs to a clean, lettable standard. Cat B is the tenant's own layout: partitions, meeting rooms, tea points, furniture power and finishes. In a small suite we often do both in one programme, because the space is handed over as a bare shell.
Does an office fit-out in New Barnet need building control approval?
Usually, if the work changes escape routes, fire doors, drainage or an accessible WC. Barnet Council is the local building control authority, and a registered building control approver can be used instead. We build to the approved plans, book the inspections and pass the completion certificate to you at handover.
Can the fit-out of a New Barnet office happen out of hours?
Quiet work can, noisy work mostly cannot. Drilling, cutting and breaking out stay within the council's permitted hours. Outside them, noisy work needs the council's agreement, usually through a prior consent under the Control of Pollution Act, and with homes nearby it is rarely granted. Where the building holds only offices and shops, noisy slots outside trading hours can be agreed with the landlord and occupiers, still within the council's rules. Decoration and second fix can carry on after hours. We agree the times in writing before the start.
Who sets up the data cabling in a small office?
Your IT supplier specifies, terminates and tests the network. We install the containment, back boxes and floor boxes to their layout while ceilings and partitions are open, and leave draw wires for later. Getting the IT supplier's drawing before first fix saves opening finished ceilings after handover.
Does moving a fire alarm point in a New Barnet office need approval?
The landlord's approval, and often building control's too. In a shared building the alarm panel and detectors usually belong to the landlord and are maintained through the service charge, so the change is made by its alarm contractor or with its written consent. Where the change is part of new partitions affecting escape, Barnet Council or a registered building control approver checks it with the rest of the fit-out.
What duties does a New Barnet business have under CDM?
A commercial client must make suitable arrangements for managing the project, appoint a competent contractor and give the information needed for the work to be done safely. On a small fit-out where we are the only contractor, we prepare the construction phase plan and manage the site. With more than one contractor, you appoint a principal designer and a principal contractor in writing.
What is reinstatement at the end of an office lease?
Many leases require the tenant to remove its alterations and hand the space back as it was let, and a schedule of dilapidations sets out what is owed. We can strip partitions, make good ceilings and floors and redecorate to the standard the landlord's surveyor asks for, so you can agree the cost and the programme before the lease ends.
