Office Fit-Out Hatfield

Office fit-out in Hatfield covers a suite on Hatfield Business Park, on the former de Havilland airfield, and smaller offices, such as a floor above a shop or a suite in an older Old Hatfield building. We strip out, build partitions and glazed screens, fit ceilings, lighting and small power, form meeting rooms, tea points and WCs, and coordinate cabling with your IT supplier. The work runs under the landlord's licence for alterations and non-domestic building regulations, delivered for Welwyn Hatfield by Hertfordshire Building Control, and it is planned around the people still working in the building.

For Hatfield, 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 Hatfield: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Office suites on Hatfield Business Park and the old airfield

Hatfield Business Park sits on the former de Havilland airfield. British Aerospace announced in 1992 that aircraft production at Hatfield would cease from 1993, and the site is now divided between the University of Hertfordshire, housing and the business park. An office fit-out here typically means a tenant taking a floor or a suite in a multi-let building with shared cores and a building manager. Before we start, a building manager will usually want a method statement, a programme, delivery times and a named contact, and we send those with the first programme.

Landlords of multi-let offices commonly hand over a Category A floor, and it helps to know where that stops. Cat A is the landlord's shell: raised floor, suspended ceiling, base lighting, heating and cooling, and toilets in the core. Cat B is your layer on top, which is the work we price: partitions, meeting rooms, a tea point, floor boxes and small power in the right places, lighting adjusted to the new layout, finishes and signage inside. Every Cat B change has to respect the landlord's fit-out guide and the building's fire strategy.

Small offices above shops and in Old Hatfield buildings

Away from the business park, office work in Hatfield is smaller in scale: a floor above a shop, a professional office or a studio. An upper-floor office usually shares one stair with the unit below, so the escape route, fire doors and alarm have to work for both occupiers. We check that before a partition goes up. A new room reached only through another room is an inner room, which Part B restricts, and a glazed screen or a door moved by a metre can decide whether the layout passes.

The Old Hatfield historic core is the only conservation area inside Hatfield, and Fore Street alone carries 15 entries on the National Heritage List for England, all at Grade II. Where an office sits in one of those buildings, the fit-out can meet historic fabric: uneven floors, timber-framed walls and ceilings that cannot take a grid. We use freestanding or lightly fixed partitions, surface cable routes and lighting that avoids cutting into old plaster. For a building on the national list, internal alterations that affect its character need listed building consent, which the owner obtains before we start.

Building regulations, CDM and working hours in a Hatfield office

An office fit-out in Hatfield is non-domestic building work, and it is checked more closely than a house. For Welwyn Hatfield the local authority service is Hertfordshire Building Control, based at The Campus in Welwyn Garden City. An office falls under the fire safety order, so a building notice cannot be used, and the work goes by full plans with drawings checked before work starts. The checks cover means of escape past new partitions under Part B, an accessible WC and door widths under Part M, and lighting controls and services efficiency under Part L. Its inspectors also examine structural beams and openings where a wall is opened between suites.

As a commercial client, your business has duties of its own under the CDM regulations, including allowing enough time and passing on what you know about the building, such as an asbestos survey. We take the contractor's duties and keep the site in order. In an occupied Hatfield office, core drilling, cutting and breaking out stay inside the council's permitted hours, timed with the landlord for the quietest part of the working day. Noisy work in the evening or at weekends needs the council's agreement, usually through a prior consent under the Control of Pollution Act, so only quiet trades such as decoration run after hours, with the fire alarm kept live throughout.

Hatfield employment sites, office-to-home rules and the lease end

Across Welwyn Hatfield, offices on the employment sites listed in the council's direction are protected as workspace. An employment Article 4 Direction confirmed on 26 January 2022 removes the permitted development right to convert offices to residential accommodation on those sites. The Local Plan Inspector's Report says it prevents offices in Class E(g) changing to homes without planning permission. The same report records a net loss of over 80,000 square metres of office floorspace in the borough between 2008/9 and 2017/18. For a tenant this is context: if your building is on one of those sites, it is expected to stay offices, and so is the market for it.

Plan the end of the lease at the start of a Hatfield fit-out. Many office leases require the space to be handed back in the condition set out in the lease, and dilapidations claims turn on what was there before. We photograph the space and record its condition before strip-out, keep the landlord's approved drawings, and build partitions, glazed screens and ceilings in a way that can be taken out cleanly. At lease end we can strip out and reinstate to the schedule, so the reinstatement is a known item rather than a dispute.

The GS Renovation Difference in Hatfield

An office fit-out has to satisfy the landlord, building control and the people still working around it, and each wants different paperwork. We survey the space, give a written quotation after the visit, and set out a programme that times the loud work around your staff, inside the permitted hours. We deal with the building manager, book the building control inspections, coordinate the registered electrician, the fire alarm installer and your IT supplier, and keep one contact for the whole job. You receive the electrical, fire alarm and emergency lighting certificates at handover.

• A programme built back from the date your staff move in
• Every new office circuit certified to BS 7671 by a registered electrician
• Honest updates if a date or a detail has to move
