Two datasets have landed this week that, read together, describe a Prime Central London (PCL) market that has stalled under its own steam.
JLL’s Q1 2026 analysis shows just 350 homes exchanged across PCL in the first quarter – down 24% on Q1 2025 and the lowest volume since 2020, with total transaction value of £743 million sitting 28% below the two-year Q1 average of over £1 billion.

At the same time, HM Land Registry’s UK House Price Index for February confirmed Westminster recording an annual decline of 12.7% and Kensington and Chelsea falling 11.2% – pulling average values in both boroughs back to levels last seen in 2013. Over a decade of price appreciation, gone.
The immediate cause is not hard to locate. Iran’s closure of the Strait of Hormuz on March 2, 2026 drove energy prices sharply higher, reigniting inflation fears and leading lenders to pull more than 1,500 mortgage products from the market (Drummonds Finance Group).
The average two-year fixed rate has risen from 4.25% before the conflict to 5.42% in April – its highest since July 2024.
JLL’s Q1 2026 data shows the brackets most exposed to financing conditions took the sharpest hits: sub-£2 million properties fell 9.8% annually, £2 million to £5 million fell 9.2%. Where leverage financing the deal was always part of the plan, the arithmetic has stopped working.
Prime London buyers rotating into lettings
What the JLL figures make equally clear is where those buyers went. They haven’t left the market, but rotated into lettings. PCL lettings rose 13% year on year in Q1, but so did available rental stock, up 29% to nearly 1,500 homes.
The picture indicates a market entering a holding pattern rather than hitting a brick wall in the form of a supply crunch, with would-be buyers parking in rentals while landlords jostle for their attention. The sales market, meanwhile, is losing the very transactions it needs to find its floor.
Westminster and Kensington and Chelsea are falling – where they are transacting at all – as buyer pools thin to a point it’s difficult to discern accurate pricing strategies, let alone what value currently looks like.
It’s worth bearing in mind that the double-digit declines are concentrated in the mid-prime bracket, broadly £1.5 million to £5 million, rather than the genuine super-prime tier where sellers have the luxury of patience.
Is a rebound on the horizon?
The question the Q1 data cannot answer is how long the wait extends. The Bank of England (BoE) has offered no clear signal on the pace of any rate reversal, and the Iran conflict shows no signs of near-term resolution.
A fairly sharp rebound remains possible if conditions improve as Chestertons – which reported a 21% drop in buyer enquiries this week – noted, but ‘possible’ is not the same as likely on any near-term timeline.
What’s certain is that the PCL sales and lettings market are now running in opposite directions, and the force driving them apart is the same: buyers who want to own but cannot yet justify the cost of doing so.
Whether a longer-term correction follows remains to be seen. What the data does suggest is that PCL is not broken – it’s waiting. The two are not the same thing, and the distinction will matter when conditions shift.
