For comparison, rents rose 4.0% across England and 3.8% across the UK over the same year. London — at £2,332, some 60% above the England average of £1,459 — is still rising more slowly than England as a whole.

The Desk’s Read — what it means

London rents rose 3.5% in the year to August 2026, up from 3.0% at the last print and the fastest rate since October 2025. That is another half a point in a single print, on top of the 0.8 the month before: London has added 1.3 points in two months. The ONS says the rise in the UK figure — 3.8%, its highest since December — was mainly London’s doing. Two editions ago London was the number holding the national rate down; it is now the number lifting it. It still sits below England’s 4.0%, and it is still the third-lowest of the nine English regions — but only just. The East of England, at 3.5%, is level with it, and the South East, at 3.0%, is the only region clearly below.

The boroughs moved up together. Camden has now risen every month since February and is +1.0% on the year, from +0.5%; at £2,819, its average rent is 7.8% above its January low. Tower Hamlets stepped up to 3.5%, from 3.0%, and for the second month running sits exactly on the London average. Greenwich firmed again, to 6.1%, and is still the only one of our four above 5%. Newham, the borough we named last month as the one that could prove us wrong, did not: it steadied at 2.9%, and its monthly reading turned back to positive, if only just. The gap between our fastest and slowest borough is unchanged at 5.1 points; three of the four simply moved up by about half a point, and Newham barely moved.

Whether London holds 3.5% from here is arithmetic, not sentiment. The annual rate compares each month with the same month a year earlier, and last autumn’s comparison months were still rising — September 2025 by 0.34%, October by 0.20%, November by 0.29%. London has to beat those just to stand still: had rents not moved at all after August, the rate would print 3.2% at the next release and about 2.7% on November’s data. The soft comparisons — last December’s fall and January’s −0.67% — do not drop out until the new year. The last two months cleared the bar comfortably, at +0.63% and +0.64%. That is what a renewal is priced against: not the headline, but the borough, the bedroom count and the direction the borough is travelling in.

Two editions ago London was the number holding the national rate down. This month the ONS says it is the number lifting it.

Four boroughs this edition — the patch we manage most closely. We widen the list as our own ledger deepens in a borough. For reference, a London one-bed averages £1,760, a two-bed £2,232, a three-bed £2,643.
What we’d tell a landlord this month

If your property is in inner, prime London, the recovery is now a trend, not a bounce: Camden has risen for seven straight months and its average rent is back above where it stood a year ago. A renewal held flat through last winter’s correction now has room above it. If it’s in an outer regeneration borough, read the two east London boroughs separately: Greenwich, at 6.1%, is still the fastest market on our patch, while Newham has not moved since June — £1,928 then, £1,928 now. The market that was running at 9% a year ago has stopped. Across London the average one-bed is now £1,760 and the average two-bed £2,232, a gap of £472 a month, which is why the bedroom count decides a valuation as much as the postcode does. Bring us the address and we’ll price the property, not the region.

The Three Clocks — how we read the market
No single source tells you where rents are now. We read three, each on a different delay.

The ONS print

This month, August 2026’s monthly rise of 0.64% annualises to about 8.0%. That is more than twice the 3.5% annual rate, and the seventh consecutive monthly rise — the last two the strongest since February. The months now being printed are running well ahead of the year they sit inside, which is why the annual rate has climbed 1.3 points in two prints. The live ledger read for this edition is attached when Harvey signs it off.
The Call — what we think happens next
For the 21 October release (September data), we expect London annual inflation to print in the 3.4–4.0% band, and in the top half of it. Two prints running, the top of our band has been the problem — July beat it and August touched it — so this band starts where last month’s ended and reaches 4.0%. The arithmetic: September 2025 rose 0.34%, so London needs a monthly rise above that to print higher than 3.5%. A repeat of August’s +0.64% would print about 3.8%; a repeat of May’s +0.17% would print about 3.3%, below our floor. What would prove us wrong on the downside is a soft month in the boroughs that have supplied the acceleration — Camden, Tower Hamlets and Greenwich all rose by more than 0.5% in August, and if those monthly rises fall back under 0.3%, the headline is unlikely to hold. On the upside, a monthly rise above 0.8% prints 4.0% or more, and only February has done that this year.

No. 03 · August 2026 releaseLondon annual rent inflation prints in the 2.9–3.5% band at the 16 September print (August data).HELDPrinted 3.5% — on the top line of our band, and only by rounding: before rounding the figure was 3.52%. We score it as held because the ONS publishes to one decimal place and the band was set to one; in hundredths it would be a miss, and we would rather say so than not. The falsifier we named — Newham’s cooling spreading across outer east London — did not fire: Newham steadied at 2.9% and Greenwich rose to 6.1%. Two prints running, the top of our band has been too low. The band moves up this month.
No. 02 · July 2026 releaseLondon annual rent inflation prints in the 2.1–2.6% band at the 19 August print (July data), with the risk to the upside.MISSEDPrinted 3.0% — 0.4 points above the top of our band. We had the direction right and the range too tight: we flagged the risk as upside, and the upside is what happened. The falsifier we named did not fire — we said a Camden roll-over would prove us wrong, and Camden did the opposite, crossing back above zero. What beat us was pace, not direction. The band widens this month.
No. 01 · June 2026 releaseLondon annual rent inflation holds in the 1.9–2.3% band at the 22 July print (June data).HELDPrinted 2.2% — inside the band, at the top of it. The band held; our stated risk skew did not. We flagged the risk as being to the downside, from Camden’s fall spreading into neighbouring prime. Camden did the opposite and rebounded to −0.5%.
