Worked example — the £50K/year office

Here's the maths, shown transparently. This is what a broker charges on a typical £50,000/year office lease:

The broker fee breakdown

Annual office rent £50,000 / year
Contract length 3 years
Broker commission rate (typical) 10% of annual rent
Broker fee per year £5,000 / year
Total broker fee over 3 years £15,000

Worst-case at 15%: £22,500 over 3 years. Direct via Seek = £0.

The broker takes this as a one-time fee at lease signing — whether they showed you two spaces or forty, whether the deal took two days or two weeks, and whether the operator already knew you existed or not.

What seekers pay using Seek — ever

How brokers actually get paid

The 10% fee isn't a law or a professional standard — it's a convention that stuck because tenants didn't know they could skip it. Brokers earn their commission from the first year's annual rent when a lease is signed. On a £100,000/year office, that's £10,000 for an introduction that increasingly happens via a platform anyway.

Some brokers charge 12–15%, particularly on shorter-term or serviced-office deals. A few charge a flat retainer on top of a success fee. All of it comes out of your negotiating room.

I spent 12 years collecting those fees.

Here's the maths I never showed clients: on a £60,000/year lease, the broker walks away with £6,000 at signing. That money came out of the deal value — money that reduced what you could afford to spend on the space, or that you could have kept in the business. The broker's incentive was to close the deal fast, not to get you the best terms. I built Seek to make my old job obsolete. This calculator is just showing you what I already knew from the inside.

Frequently asked questions

Is the 10% broker fee negotiable?
Sometimes. Brokers will occasionally drop to 8% on large deals or long-term relationships. But the more important question is whether you need to pay any fee at all — which with Seek, you don't.
Does the broker fee come out of my rent?
The broker fee is typically charged to the tenant at lease signing — separate from your rent. It's a one-time payment equal to approximately 10% of your first year's annual rent. The tenant always bears the cost.
Do I need a broker to find office space?
No. Platforms like Seek list spaces direct from operators. You get the same buildings, the same operators, the same spaces — without a broker taking 10% at signing. The market has changed; broker habits haven't.
How accurate is this calculator?
The 10% figure is the industry standard for UK commercial office space broker fees. Some brokers charge 8%, some 15%. This calculator shows the standard rate and worst-case. Your specific broker contract governs the exact amount.
Which currencies does the calculator support?
GBP (British pounds), EUR (euros), USD (US dollars), and SGD (Singapore dollars). The fee calculation works identically — 10% of the annual rent in whichever currency you're using.
