The Squeezed Middle: Why Growing Businesses Can’t Find Good Office Space in London — and What to Do About It

By Fraser Williams, Director, Morgan Pryce

London’s SME occupiers face a structural squeeze in 2026: around 70–80% of leasing is concentrated in Grade A space, prime West End vacancy sits below 2%, and sub-10,000 sq ft transactions fell 25% in Q1 2026 to their lowest level since 2021 — not because smaller businesses don’t want space, but because well-priced quality space is scarce and corporates are competing for the same buildings.

The Market Is Busy. So Why Can’t You Find Anything?

Read the headlines and the London office market looks healthy. Q1 2026 leasing reached 2.2 million sq ft across 152 transactions — up 6% on last year and slightly ahead of the ten-year average. Active demand has been running around 50% above its long-term norm. Now read the small print. Sub-10,000 sq ft transactions in Q1 2026 were down 25% on the quarterly average — the lowest level since 2021 — and the fall was even steeper below 5,000 sq ft. Larger occupiers are transacting with confidence; smaller ones have gone quiet. The big agencies interpret this as SME caution. Having spent this year in the trenches with growing businesses, we would put it differently: it is not that SMEs don’t want to commit — it is that the market has made it genuinely hard for them to commit well.

Three Forces Squeezing The SME Occupier

1. Corporates Are Shopping In Your Aisle:

The defining behaviour of this cycle is quality over quantity: occupiers taking 15–30% less space than pre-pandemic, but insisting on better buildings. Sub-10,000 sq ft deals drove more than 55% of West End transactions in 2025 — and a large share of those “small” deals are large companies taking boutique, high-spec floors. The 4,000 sq ft suite that once had two SME bidders now has a corporate on the shortlist too.

2. The Supply Pipeline Is Thin And Pre-Sold:

New completions in 2026 are forecast around 1.2 million sq ft—down roughly 40% year-on-year—and about 70% of that was pre-let before delivery. Prime West End vacancy is under 2%. What remains is contested, and it moves fast, often before formal marketing.

3. The Quality Bar Has Risen Faster Than Budgets:

With 70–80% of take-up concentrated in Grade A space and sustainability now effectively a leasing prerequisite, the gap between “space you can afford” and “space your team will actually come into” has widened. Meanwhile, business rate shifts in the 2026 revaluation (Farringdon +38%, Shoreditch +16%) have pushed some traditional SME heartlands up the cost curve.

The Good News: The Squeeze Creates Openings

A polarised market punishes the unprepared but rewards the well-advised. Four strategies working for our clients right now:

Look One Postcode Over:

The 2026 rates map rewards lateral thinking: East City/Aldgate rose just 5% while neighbouring Shoreditch jumped 16%; Bloomsbury actually fell 5% and London Bridge fell 11%. Character and connectivity increasingly exist outside the obvious pins on the map — the “flight to character” trend means well-refurbished period buildings in emerging pockets now compete directly with glass towers.

Take Plug-And-Play Seriously:

CAT A+ and fitted suites carry rent premiums of 12–20%, yet for sub-5,000 sq ft requirements they frequently win on total cost once fit-out capex, dilapidations exposure and time-to-occupation are counted. Flexible workspace now represents around 10% of Central London stock, up from 6% pre-pandemic — the options are real and improving.

Use The Corporates’ Timetable Against Them

Large occupiers commit years ahead; they rarely fight over space available in the next two quarters. SMEs able to move decisively on immediately available floors face less competition than the headline scarcity suggests. Speed — underwritten by preparation — is the SME’s structural advantage.

Negotiate The Stack, Not The Rent

In tight submarkets, the headline rent may not move. Rent-free periods, service charge caps, landlord contributions and flexible break options often will. That is where the deal is won.

The Strategic Point

The sub-10,000 sq ft slowdown is not a demand story — nearly half of active occupiers surveyed heading into 2026 were looking to increase space, against only around a fifth looking to shrink. Growth intent is there. What is missing, for many smaller businesses, is a route through a market that has become institutional in its complexity.
That route exists. It starts earlier than you think, looks wider than the obvious postcodes, and negotiates more than the rent.
