Read the headline and you'd think London rents were running away again. Read the small print and there's a very different story.
What are London rents doing?
Advertised London rents rose 7.6% year on year in October, to an average of £2,401 a month, according to lettings firm Hello Neighbour. That's six months in a row of annual growth since the Renters' Rights Act came in, and up from 6.1% in September.
So are tenants paying 7.6% more?
No. Those are asking rents on Hello Neighbour's own listings. On the London homes it listed from August to October that have since let, the agreed rent came in 4.4% below the advertised rent.
Other measures are calmer too. The ONS puts the average London rent at £2,338, up 3.5% in the 12 months to September. HomeLet, which tracks rents agreed on new tenancies, had London at £2,272 in September, up 3.3%.
Why are asking rents running ahead?
Partly the new rules. Under the Renters' Rights Act, landlords can't accept offers above the advertised rent, and rent increases are limited to once a year. So some landlords are listing high from the start. Supply plays its part as well: Zoopla says the number of London homes available to rent is 6% lower than a year earlier, and 13% lower in inner London.
Is demand cooling?
A little. Hello Neighbour's enquiries per property fell to 30 in October from 34 in September, against 56 in October 2024.
What does it mean for renters in Clapham, Brixton and Streatham?
The asking price is a starting point, not a verdict. Look at what similar flats have actually let for. In my experience across SW4, SW9 and SW16, well-priced flats are generally letting at the asking price, so the London-wide discount doesn't show up round here the same way. Offer below only where a flat has sat or looks overpriced.
What does it mean for landlords?
Over-pricing costs you twice. Every week empty is rent you never get back, and you can't make up for a weak start with a quick rise later. Increases come once a year through a section 13 notice, with two months' warning, and tenants can challenge them at tribunal.
A two-bed conversion off Brixton Hill or a one-bed near Streatham station priced right on day one will usually let faster to a better tenant than one sat on Rightmove waiting for a miracle.
My take
Here's the thing: across London, the headline number is the landlord's wish list and the agreed number is the market. Generation Rent has more bargaining power than the London headlines suggest. Round here, though, well-priced flats are usually letting at asking, so the discount is for the ones that have sat or been pitched too high. Good landlords should still welcome a well-priced, quick let over a long void.
So there you have it. Renters, negotiate where a flat has sat or looks overpriced. Landlords, price for the deal, not the headline.
