Office fit-out in Grays is work on modest spaces: a first floor above a shop in the town centre, a suite in an older town centre building, or a small practice taking a ground floor unit. Thurrock's Core Strategy seeks to direct office development to its town centres, and Grays is one of them. We strip out, build partitions and ceilings, run lighting and small power, coordinate cabling with your IT supplier and fit the tea point and WCs, so your team can move in on a set date.
For Grays, 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 Grays: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Office space in Grays is small suites around the civic core
Grays is not a business park, and an honest office fit-out here reflects that. Thurrock's Core Strategy seeks to direct office development to the town centres on its Key Diagram and to the Key Strategic Economic Hubs, and Policy CSTP7 makes Grays town centre the focus for cultural, administrative and educational functions. Thurrock Town Hall and the Civic Offices on New Road anchor that role, and the office space around them is modest in scale.
The office work that arises in a town centre of this size is floors above shops, rooms in older buildings and ground floor units used by professional practices, agencies, tutors and care providers. Floor plates are small and often awkward, with a narrow stair, a single WC and windows on one side only. The design work is about getting a meeting room, open desks, storage and a tea point into that footprint without blocking the escape route.
Cat A, Cat B and the landlord's licence for a Grays office
Two terms come up on any Grays office lease. Cat A is the landlord's base finish: ceilings, lighting, raised floors or trunking, heating and cooling, and WCs, with the floor left open. Cat B is the tenant's own fit-out on top of that: partitions, meeting rooms, the kitchenette, finishes, furniture and data points. In a smaller older building there may be no real Cat A at all, so the job starts from a stripped shell and covers both.
Before either starts, the lease will usually require the landlord's licence for alterations, with drawings and a description of the works. Allow time for that, because the landlord's surveyor may comment on partitions, ceiling fixings and anything that touches the building's services. Keep the approved drawings. At the end of the lease they decide what must be stripped out under dilapidations and what can stay, and a clear record makes that conversation shorter and cheaper. We keep a photographic record of the space before we start.
Building regulations for a Grays office fit-out sit with Thurrock
Thurrock Council is a unitary authority and runs its own building control service for Grays, so one council deals with planning and building regulations unless you appoint a registered building control approver. An office fit-out is non-domestic work, and the checks weigh fire and means of escape (Part B), access for disabled staff and visitors (Part M), and the energy performance of new lighting and heating (Part L). Moving a partition across an escape route or adding a WC brings the job into building control.
Thurrock states that a building control plan approval is valid for 3 years from the date the plans are deposited, and the work must commence within that time. For larger developments, it carries out inspections booked before 10am on the same day. On a small Grays suite the timetable is set more by the landlord's consent and your move date, but the approval and inspection stages still sit inside our programme, never after it.
Working in an occupied Grays building without stopping the business
An office in Grays may share a building with a shop below or other tenants on the same stair, so the fit-out is phased around people at work. Noisy stages such as cutting ceilings, chasing walls and fixing partitions stay within the council's permitted hours. Thurrock can serve a notice on construction work that controls how it is done, including hours. Noisy work outside those hours needs Thurrock's prior consent, and near homes it is rarely granted. A prior consent application is free when made 28 days or more before the start. Where no homes are affected, quiet work such as decoration and second fix can run after hours with the landlord's agreement.
A business client also carries duties under the CDM regulations that a homeowner does not. You make suitable arrangements for the project, give the contractor the information you hold about the building, such as the asbestos survey, and allow enough time and resources. We plan the Grays job around that information, keep the site separate from occupied areas with screens and locked doors, and hand over with the test certificates for the lighting, power and fire alarm.

Working With GS Renovation in Grays
An office fit-out has a fixed date that the move, the leases and the IT all hang on. We build the programme backwards from that date, agree the layout and finishes with you, and run strip out, partitions, ceilings, first fix, second fix and decoration in that order. A registered electrician tests and certifies the installation, and we coordinate the data cabling with your IT supplier. You get a written quotation after a site visit, and one contact from survey to handover.

FAQ
Frequently Asked Questions about Office Fit-Out Grays
How much does an office fit-out cost in Grays?
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 office space to fit out in Grays town centre?
Yes, on a small scale. Grays is one of the town centres defined in Core Strategy Policy CSTP8, and the Core Strategy seeks to direct office development to those town centres. Expect floors above shops and small suites in older buildings rather than purpose built office blocks.
What is the difference between a Cat A and a Cat B fit-out?
Cat A is the landlord's base finish, with ceilings, lighting, heating, WCs and an open floor ready for a tenant. Cat B is the tenant's own layout on top: partitions, meeting rooms, the kitchenette, finishes and data points. In a small older building both are often done together from a stripped shell, and we price them as one job.
Who does building control for an office fit-out in Grays?
Thurrock Council runs its own building control service for Grays, and as a unitary authority it handles planning as well. A registered building control approver is the alternative. An office falls under the Fire Safety Order, so the application is full plans, not a building notice. The officer checks fire safety, escape routes, access and the energy performance of new lighting and heating, with inspections booked as each stage is reached.
How long does a Thurrock building control approval last for Grays work?
A Thurrock building control plan approval is valid for 3 years from the date the plans are deposited, and the work must commence within that time. For an office tenant that is rarely the constraint, because the move date and the lease drive the timetable, but it matters if a fit-out is approved and then delayed.
Can office fit-out work in Grays be done out of hours?
Quiet work can, such as decoration and second fix, with the landlord's agreement. Drilling, cutting and strip out stay within the council's permitted hours, and Thurrock can control the hours of construction work by notice. Noisy work outside those hours needs Thurrock's prior consent, which is rarely granted where homes are nearby. The application is free when made 28 days or more before the start.
Can a larger Grays office project get same-day building control visits?
For large developments, Thurrock Building Control carries out inspections booked before 10am on the same day. A small suite follows the ordinary booking route. Either way we book each inspection before the stage is covered, so partitions and ceilings are never closed up over work that has not been seen.
Does an office tenant need the landlord's consent before a fit-out?
Usually, yes. Most commercial leases require a licence for alterations before partitions, ceilings or services are changed, and the landlord's surveyor reviews the drawings. We supply the method statement and programme the surveyor asks for, and start work on site once the licence is signed.
What happens to the fit-out when the office lease ends?
The lease decides. Dilapidations clauses often require the tenant to strip out their alterations and reinstate the space to its original state, unless the landlord agrees otherwise. We can carry out that reinstatement at the end of the term, and keeping the approved drawings from the start shows what was added.
