How much does an office fit-out cost?
A full Cat B office fit-out outside London is published at about £300–£700 per m², and £500–£1,500 per m² in London. Cat A items such as ceilings and raised floors are priced separately.
| Item | Typical cost |
|---|---|
| Cat B fit-out, outside London | £300–£700 per m² [1] |
| Cat B fit-out, Manchester, Leeds, Birmingham | £350–£600 per m² [1] |
| Cat B fit-out, London | £500–£1,500 per m² [1] |
| Cat A: suspended ceiling | £30–£60 per m² [1] |
| Cat A: raised access floor | £40–£80 per m² [1] |
| Cat A: lighting, HVAC and fire services | £50–£120 per m² [1] |
| Furniture, per workstation | £1,500–£5,000 [1] |
Worked example. A 400 m² regional office at £300–£700 per m² gives a Cat B budget of roughly £120,000–£280,000, before furniture.
What changes the price
- Floor area and the starting condition of the space
- Cat A or Cat B, and the level of finish
- Mechanical and electrical changes
- Number of meeting rooms, kitchens and toilets
- Location: London rates are much higher than the rest of the UK
Rules to budget for
Fit-outs fall under the Construction (Design and Management) Regulations 2015, so roles, plans and safety information need to be in place. Building Regulations apply to fire, escape routes and many layout changes.
