Price Growth Gap in London Widens to Brexit Levels as PCL Buyers Circle
July 2025 PCL Sales Index: 5,134.6 July 2025 POL Sales Index: 275.7

The London property market is more split than it has been since Brexit.
Average prices fell 3% in prime central London (PCL) in the year to July due to doubts around the governmentās treatment of wealthy foreign investors.
Meanwhile, there was an increase of 0.6% in prime outer London (POL), in a market largely driven by domestic buyers moving due to changes in their personal circumstances.
The last time the gap was wider was in 2017, when prices in central London were correcting after the EU vote in June 2016. Demand was kept in check by an inconclusive general election a year later and the spectre of a no-deal Brexit created a subdued mood in 2018 and 2019, as the chart shows.

Fast forward to 2025 and a similar gap is opening up. We face a summer of speculation as the government comes under pressure to tweak the rules that have replaced the non-dom regime.
Under the old system, non-doms could live in this country without paying UK tax on their overseas wealth. The new rules impose a residence-based framework with a four-year time limit and a proposal to charge inheritance tax (IHT) on global assets.
The changes have had real-world consequences, with wealthy foreign investors departing and adding to the pressure on government finances, as we recently flagged.
Underlining how the London property market has been affected, the average number of exchanges in south-west London in the first seven months of this year was 1% below the five-year average. In prime central London, the equivalent decline was 10%.
āBuyers will generally jump on a property if itās priced correctly,ā said Luke Ellwood, head of south-west London sales at 51ĀŅĀ×. āWe are currently not far from last yearās position, which was a record 12 months for us.ā
Overall, it was a bumpy start to the year thanks to a stamp duty cliff edge in April, which saw activity pulled forward into the first quarter. However, last weekās dip in swap rates following weak US jobs data would have further supported the sort of domestic demand that drives the market in POL.
Despite the relatively subdued mood inside zone 1, more buyers in PCL are attracted by the relative value on offer, according to Stuart Bailey, head of prime central London sales at 51ĀŅĀ×.
Average prices are 20% below their last peak in August 2015, which compares to an equivalent decline in POL of 7% since mid-2016.
āSome buyers have now been to places like Italy and Dubai and realise they still want a long-term base in London.ā said Stuart. āWhen they see prices in Belgravia within 10% to 15% of areas like Fulham it is tempting some of them to look in more central areas.ā
It is still a buyerās market across most of the capital due to high levels of supply. An overhang from the stamp duty cliff edge, decisions put off due to last yearās general election and a growing number of landlords selling up are among the causes.
However, the picture is slowly improving as the distortive effect of Aprilās stamp duty increase passes through the system.
There were 6.7 new buyers for every new sales instruction in July in PCL and POL, which was lower than a figure of 7 last July, but itās an improvement on 5.1 in April.
However, we would expect the price growth gap between PCL and POL to widen for now.
