The story so far — Bureau of Silly Ideas

We secured a 10-year lease at a sustainable rent — the first of our leases to come up for review, covering three of our arches. As far as we know, BOSI was the first Arch Co tenant to bring a rent dispute of this kind to court. Both sides presented their case. The landlord's proposed 155% increase (£11k → £28k) was not upheld, and the matter resolved on different terms.

The process nearly broke us. Money we'd budgeted for freelance artists and producers to make our work went on lawyers and court costs instead. In situations like ours, the cost of enforcing your legal rights can intimidate tenants into different decisions — many concede before they reach a courtroom, not because the law isn't on their side, but because the cost of getting there is unaffordable.

What happened next

Within days of the rent matter settling, Arch Co served a six-month break notice on all of our leases on redevelopment grounds. We now have until autumn 2026 to respond.

We have a pro bono legal team engaged, and we believe we have substantive grounds. We won't set out our legal arguments here — those belong with our lawyers, in the right forum, at the right time. Two things, though, are already on the public record:

Arch Co's own planning application (Lambeth ref. 26/00491/FUL) describes our occupied, leased arches as "derelict." They are not.

Arch Co previously argued — in submissions to Lambeth Council — that this estate was low-value, in support of removing it from the Creative Enterprise Zone. In the rent matter, the same estate was argued to be high-value. Both positions are on the record.

These are public observations, not legal arguments. The legal case stays with our lawyers.

Why this matters for ~1 million UK commercial tenants

We're not alone. We sit alongside other cultural occupiers and independent traders who have been here for decades — many of them small businesses rooted in Brixton's migrant and Black-led communities, making a unique space under the railway lines since the 1940s.

We have been told directly by Arch Co's asset management team that these other occupiers are also expected to be served notice as part of a wider standardisation strategy across the estate: refurbish and re-let at uniform commercial rates.

That is a legitimate commercial direction. It also ends, in one decision, the post-war heritage these arches have been building over eight decades — and the small-trader and cultural ecology that has grown alongside it. BOSI is one tenant in that picture. The picture is much bigger than us.

It's even bigger than Brixton.

The bigger picture

Arch Co owns nearly every railway arch in the UK.
Around 80% of the UK's roughly one million rented commercial properties are held by institutional investors like Arch Co.
These leases are routinely contracted out of the Landlord and Tenant Act 1954 — removing statutory tenant protections as a matter of standard practice, and leaving tenants completely vulnerable.
Since Arch Co took over the arches, 1,344 protected tenancies have been lost.
Monopoly landlords now offer 100% of new lettings contracted out of the 1954 Act.

"You cannot start a business with these statutory rights."

— Derec Hickman, Guardians of the Arches

This is lawful. The question is whether the 1954 framework — designed to protect small businesses, and now operating in a market dominated by institutional investors — is still doing what it was originally written to do.

Commercial tenants have no shared voice yet. Most negotiate alone. Part of what this campaign builds is the start of one — a record, a network, and the conditions for collective dialogue with the institutional landlord sector.

Not again.
