You should budget for headline rent plus a further 40–60% to cover service charges, business rates, insurance and utilities, then add one-off costs such as a deposit, legal fees and fit-out.
Headline rents in central London currently range from around £50 per sq ft in parts of Shoreditch to well over £150 per sq ft in Mayfair, so location has the biggest single impact on your budget.
As a rough guide, a 2,000 sq ft West End office can cost around £300,000 a year once everything is included.

What Added Costs Should You Budget For in Central London?
The main added costs are service charges, business rates, insurance and utilities, which together can add 40–60% to your rent in Central London.
- Service charge: Typically £5–£15 per sq ft, covering shared areas, cleaning of common parts, lifts, security and building management. Prestige buildings with concierge and amenity floors sit at the top end.
- Business rates: Often equivalent to around 40–50% of the rent. Rates are based on the property’s rateable value, which was reassessed in the 2026 revaluation. You can estimate your business rates on GOV.UK before you commit.
- Insurance: Contents and public liability cover, usually £1,000–£3,000 a year for a small to medium office.
- Utilities and connectivity: Electricity, water and broadband, typically £2–£4 per sq ft.
- Cleaning, maintenance and IT support: Often overlooked, but easily several thousand pounds a year.
We cover each of these in more detail in what are the added costs of renting an office space in London.
What One-Off Costs Should You Plan For in Central London?
One-off costs can be significant, particularly in the first year. Plan for:
- Rent deposit: Usually three to six months’ rent, although some landlords accept a bank guarantee instead.
- Legal fees: Around £2,000–£6,000 for your own solicitor, depending on the size of the deal.
- Fit-out: Anywhere from £50 to £150 per sq ft or more, depending on specification. A fully fitted space can reduce or remove this cost.
- Furniture and IT: Desks, chairs, meeting room technology and network equipment.
- Moving costs: Removals, IT migration and temporary disruption.
- Dilapidations: Not an upfront cost, but you should set money aside. Returning a space to its original condition often costs £15–£35 per sq ft at the end of the lease.
What Does a Central London Office Budget Look Like?
Here is a worked example for a 2,000 sq ft office in Soho at £90 per sq ft, suitable for around 18–22 people:
| Annual Cost | Estimate |
|---|---|
| Rent (£90 per sq ft) | £180,000 |
| Service charge (£10 per sq ft) | £20,000 |
| Business rates (approx.) | £85,000 |
| Insurance | £3,000 |
| Utilities and connectivity | £6,000 |
| Cleaning, maintenance and IT support | £10,000 |
| Total annual cost | £304,000 |
That works out at roughly £152 per sq ft all-in, or around £14,000–£17,000 per person per year. On top of this, the first year might include a £45,000–£90,000 deposit and a fit-out budget of £100,000 or more if the space is unfitted.

How Can You Reduce Your Office Budget in Central London?
You can reduce your office budget by negotiating hard on incentives, choosing your location carefully and sizing the space accurately.
- Rent-free periods: On longer leases, landlords often offer several months rent-free, which can significantly lower your effective rent.
- Fitted space: Taking a ready-fitted office avoids the upfront cost of a fit-out.
- Fringe locations: Moving a few streets from a prime core can save tens of pounds per square foot.
- Right-sizing: Hybrid working means many teams need less space than they think.
- Small business rate relief: Smaller offices with lower rateable values may qualify for relief.
An experienced agent can also benchmark service charges and challenge costs that look out of line with the market.
