Why the timing of your lease expiry matters

Office space moves fast — especially in London, Manchester, and other cities with high demand. The best operators pre-fill their buildings 3–6 months before lease expiry dates, not after. If you're looking at the same time as your lease ends, you're negotiating with whoever's left.

Most tenants underestimate this window. They start looking when their lease is down to 90 days and discover that good buildings are already signed, operators have moved on to the next tenant, and what remains is either expensive or not right.

This calculator works backward from your lease end date to give you a realistic timeline — and shows you the broker fee you're about to pay if you don't go direct.

How Seek works for tenants

Seek connects you directly with office operators — no broker, no commission. You browse spaces, submit an enquiry, and the operator responds. The broker fee that normally lands at lease signing goes back into your business.

Frequently asked questions

When should I start looking for a new office?
Start looking 6 months before your lease ends. The best operators and buildings get signed 3–6 months ahead of lease expiry. Below 3 months, you're working with what's left on the market.
Is 6 months lead time really necessary?
Yes. From first viewing to signed lease typically takes 4–8 weeks. Fit-out, legal review, and operator onboarding add time. Start at 6 months and you negotiate from strength — below 3 months, you accept what's available.
Does a broker charge a fee on my new office?
Yes — typically 10% of annual rent at lease signing. On a £60,000/year office that's £6,000. With Seek you pay £0. The operator deals direct with you from the first conversation.
What if my lease is in a city not listed?
Select the closest match and we'll tailor the timeline and shortlist to your city. The 6-month lead time principle applies regardless of location.
Can I embed this calculator on my site?
Yes. Use the embed iframe at /tools/lease-expiry-calculator/embed — no dependencies required, works on any site.
