Chelsea Bloom on why the commercial market is starting to look uncomfortably like the residential one

FARRINGDON — A commercial letting agent I’ve known for years has a line he trots out at every renewal: “Office rent follows residential rent up the hill about eighteen months behind, like a dog on an extending lead.” This month he finally showed me the numbers behind the joke, and they weren’t especially funny.

Prime office space in several inner-London postcodes has repriced sharply over the past two years, tracking almost exactly the curve behind an average residential tenancy that now sits at roughly £2,280 a month. The commercial version of that number carries an extra zero and a service charge nobody quite explains, but the shape of the graph is identical. Landlords in both markets are pricing the same scarce commodity: square footage in a postcode people are still willing to pay almost anything to be near.

The client meeting that starts on the platform

I sat in on a pitch last week at a mid-sized accountancy firm near Moorgate. Two of the four people in the room arrived nine minutes late, having been held at Bank on a line that was, according to the app, running “good service.” The partner leading the pitch didn’t mention it once the meeting started, which told me more than any complaint would have. Everyone in the room has simply absorbed this particular flavour of delay as background noise, the way you’d absorb weather.

That absorption has a cost, even when nobody names it. Billable hours lost to commute buffer time, meetings rescheduled around known pinch points on the network, client-facing staff choosing roles closer to home over marginally better offers further out — none of it appears on a quarterly report, and all of it is real.

Why the extra office space never quite arrives

Ask why the borough doesn’t simply approve more commercial floorspace to relieve the pressure, and the conversation arrives, predictably, at planning. A conversion of a tired 1980s office block into modern flexible workspace two streets from where I’m writing this has been “in determination” for four years, part of a pattern this paper has documented at length — a system that can, in the worst cases, take a generation to clear a straightforward change of use. Businesses that might have leased that space instead compete for the existing stock, and the existing stock prices accordingly.

A local Chamber of Commerce representative I spoke to put it bluntly: “We spend more time lobbying on planning timelines than on business rates now, and rates used to be the only thing anyone shouted about.” That’s a genuine shift in priorities for an organisation that has spent decades treating rates as its signature grievance.

What this means for where London does business

Firms priced out of the traditional core aren’t leaving London. They’re relocating to secondary clusters — Croydon, Stratford, parts of Ealing — where rent is lower but the same transport reliability questions apply in a different shape. A logistics company that moved its back office to Croydon last year told me the rent saving was real, but the recruitment pool shrank noticeably, because candidates weighing a Croydon commute against a central London one increasingly choose neither.

None of this is a crisis in the dramatic sense. It’s a slow redistribution of cost from one line item to another, from rent to recruitment to lost billable time, none of it large enough on its own to make a headline, all of it adding up to a city that is quietly more expensive to do business in than the topline figures suggest.

The recruitment problem that isn’t really a recruitment problem

A recruitment consultant specialising in professional services placements told me she’s rewritten how she pitches roles to candidates over the past two years, leading with commute time from likely home postcodes rather than salary alone. “A candidate will turn down an extra £3,000 a year if the alternative role saves them forty minutes each way,” she said. “That used to be unusual. Now it’s most weeks.” Firms that haven’t adjusted their offers accordingly are, in her account, losing strong candidates to competitors who worked this out first — not on pay, but on geography.

That shift changes where firms choose to locate new hires even within a single office, with some now running satellite desks in outer boroughs specifically to shorten the worst commutes for otherwise strong candidates who’d rule out a central role entirely. It’s an unglamorous adaptation, invisible on a floor plan, and it’s happening across more firms than any of them would readily admit to a competitor.

What the landlords say, off the record

Not every landlord is thriving on this dynamic. Several commercial agents told me privately that void periods on secondary office stock — buildings a notch below prime but still centrally located — have lengthened noticeably, as tenants either pay up for the best-connected addresses or shift toward cheaper, less central options entirely. The middle of the market, historically the safest tier for steady occupancy, is where the strain is actually showing first.

That’s a genuinely uncomfortable finding for anyone modelling London commercial property as a low-volatility asset class. The safest tier isn’t safe anymore, and nobody has quite agreed yet on what replaces it.
