Where office space sits in Staines-upon-Thames
Policy SP1 of the adopted Spelthorne Local Plan names Staines-upon-Thames as the principal town centre in the borough and a key focus for employment. Policy EC1 directs new office and research and development floorspace first to the town centre and to the Strategic Employment Areas, and permits refurbishment and redevelopment of sites in those areas for employment use. For a business looking for space in Staines-upon-Thames, those are the locations the Local Plan points office space towards.
Some office stock is also leaving that use. The Local Plan notes that Class E premises, which include offices, can be converted to homes under Class MA without planning permission, subject to prior approval. That is a matter for building owners rather than tenants, but it means a landlord may have plans for the building that outlast your lease. We check with the landlord what the building's plans are before you commit to a long fit-out programme.
If the building is listed, the works themselves are a separate question: anything that affects its character, inside or out, needs listed building consent from Spelthorne Borough Council, and carrying it out without consent is a criminal offence.
Full Plans and fire escape drawings for a Staines-upon-Thames office
Spelthorne Building Control says work to create or alter an office or other workplace can only go ahead after a Full Plans submission. New partitions change escape routes, fire detection and emergency lighting, so even a modest Staines-upon-Thames office fit-out goes through this route. Your designer prepares the drawings and makes the submission, and we price and programme from them, starting on site once the approved set is in hand.
Spelthorne also asks for two extra copies of the drawings showing fire precautions and means of escape, so it can consult the Fire Brigade. The same approval covers Part M access to any new WCs and Part L for new lighting and controls. On an office that means travel distances, door fire ratings, glazed screens and the alarm layout are fixed early. We then build exactly what the stamped fire drawings show, and record any change for the completion inspection.
Fitting out a Staines-upon-Thames office inside an occupied building
An office fit-out in Staines-upon-Thames can happen with other tenants working on the floors above and below. Spelthorne's recommended hours for noisy work are 8am to 6pm on weekdays and 8am to 1pm on Saturdays, and a building landlord may ask for drilling and cutting to happen before or after office hours instead. We agree the noisy windows with the managing agent in writing, and plan core drilling, strip-out and demolition around them.
Quiet trades are easier to place. Spelthorne allows quiet work such as painting and decorating outside the recommended hours, so decoration, carpet tiling and furniture assembly can run in the evening when the building is empty. Goods lifts, loading bays and car park space are booked through the building manager. As the client you also have duties under the CDM regulations, so we give you the construction phase plan and explain who holds each role before the start.
Cat A, Cat B and the end of a Staines-upon-Thames office lease
A Cat A finish is the landlord's base: raised floors, suspended ceilings, lighting, heating and cooling, and working toilets, with open space and no partitions. Cat B is the tenant's layer on top: meeting rooms, glazed screens, a tea point, data cabling co-ordinated with your IT supplier, signage and furniture. In Staines-upon-Thames we build either, and on a Cat B job we check the landlord's licence for alterations covers every item before work starts.
At lease end the order reverses. Dilapidations clauses often require the tenant to strip out Cat B work and reinstate the Cat A finish, and a schedule from the landlord's surveyor lists what must go. Where a change away from office use needs planning permission, Policy EC1 asks for at least 24 months of active marketing evidence first, so a landlord taking back a floor will often want it ready to re-let as an office. We strip out, reinstate ceilings and floors and make good to the schedule.

FAQ
Frequently Asked Questions about Office Fit-Out Staines-upon-Thames
What should a business budget for an office fit-out in Staines-upon-Thames?
Treat the UK guide of £70 to £120 per square foot for the construction work (Oktra, 2026) as a floor; London all-in figures run £148 to £359 per square foot (Cushman and Wakefield, 2026). Add the landlord's fees for the licence for alterations, any dilapidations at lease end, and your IT and furniture, which sit outside the building work. A Staines-upon-Thames quote follows a survey of the space.
Does an office fit-out in Staines-upon-Thames need building regulations approval before work starts?
Yes. Spelthorne Building Control says work to create or alter an office or other workplace can only go ahead after a Full Plans submission. Your designer submits the drawings, and we start on site once they are approved. New partitions alter escape routes and fire detection, which is why even a small office falls under this route.
Why does Spelthorne want extra fire drawings for a Staines-upon-Thames office?
Spelthorne asks for two extra copies of the drawings showing fire precautions and means of escape, so it can consult the Fire Brigade. Those drawings mark the escape routes, fire doors, alarm points and emergency lighting. We build from them without substitution, because any change to a door rating or a glazed screen would have to go back for review.
Where does Spelthorne want new office space in Staines-upon-Thames to go?
First to the town centre and the Strategic Employment Areas. Policy EC1 directs new office and research and development floorspace there, and permits refurbishment and redevelopment of sites in those areas for employment use. For a tenant, a floor in one of those locations sits where council policy supports office use, which helps when you are weighing a long lease and a Cat B fit-out.
Can office fit-out work in Staines-upon-Thames happen in the evenings?
Quiet work can. Spelthorne recommends noisy work between 8am and 6pm on weekdays and 8am to 1pm on Saturdays, and allows quiet work such as painting and decorating outside those hours. Evening shifts suit decoration, carpet tiles and furniture in an occupied building. Drilling and strip-out stay in the agreed daytime windows.
Could a Staines-upon-Thames office building be converted to flats instead?
That is the building owner's decision, not the tenant's. The Local Plan notes Class E premises, which include offices, can become homes under Class MA with prior approval. Policy EC1 separately asks for at least 24 months of active marketing before accepting a change away from employment use where permission is needed. For a tenant, the practical question is simply how long the lease runs.
What is the difference between a Cat A and a Cat B office fit-out?
Cat A is the landlord's base finish: ceilings, raised floors, lighting, heating and cooling and toilets in an open floor. Cat B is the tenant's layout on top of it: partitions, meeting rooms, a tea point, data cabling, finishes and signage. Some tenants take a floor at shell stage and pay for both, so we price whichever applies.
Who installs the data cabling in an office fit-out?
Your IT supplier normally specifies and terminates the data network, and we co-ordinate with them. We build the containment, floor boxes and ceiling routes to their layout, leave draw wires where needed, and programme their visit after first fix and before ceilings close. That keeps the cabling tidy and avoids lifting finished ceiling tiles later.
What duties does a business have as the client under the CDM regulations?
A commercial client must make suitable arrangements for managing the project, allow enough time and resources, and provide pre-construction information such as asbestos surveys and drawings. On a project with more than one contractor, the client appoints a principal designer and principal contractor in writing. We explain each duty at the start and prepare the construction phase plan.
