This year marks 60 years since the historic merger of Kensington and Chelsea in 1965, a
union that created one of London’s most prestigious and resilient property markets. To
celebrate the milestone, Marsh & Parsons has taken a deep dive into the data, analysing
three decades of sales across the Royal Borough and comparing it with the wider Prime
Central London (PCL) market.
The result is our 60 Years of a Royal Marriage Market Report, and it reveals just how
dominant Kensington and Chelsea have remained.
A borough that continues to outperform
Driven by world-class amenities, architectural heritage and enduring international appeal, the
Royal Borough of Kensington and Chelsea has delivered the strongest average house price
growth of any London borough over the past 20 years. According to Zoopla, average values
have risen by 124%, from £504,000 to £1.13 million.
But it’s not just price growth that sets the borough apart. When it comes to total sales value,
Kensington and Chelsea continue to outpace the rest of PCL, with Kensington, in particular,
consistently recording higher transaction volumes than its Chelsea neighbour.
Kensington vs Chelsea: closely matched, but subtly shifting
Looking at townhouse sales between 1994 and 2024, prices per square foot in Kensington
and Chelsea have tracked remarkably closely for most of that period. However, over the past
two years, Kensington has edged slightly ahead in achieved values.
That said, houses across the wider PCL market, including Mayfair, Belgravia, St James’s
Knightsbridge, have continued to command a premium. In 2024, average prices reached
£2,284 per sq ft across PCL, compared to £1,952 per sq ft in Kensington and Chelsea,
reflecting a 15% differential.
Activity tells its own story
Transaction volumes between Kensington and Chelsea began to diverge in the early 2000s.
From 2003 onwards, Kensington consistently recorded higher levels of sales activity – a
trend that has persisted through multiple market cycles. While both areas mirror wider
market fluctuations, Kensington’s depth of stock and broad buyer appeal have helped it
outperform on volume year after year.
Record-breaking moments in Prime Central London
The Royal Borough has also been responsible for some of London’s most notable residential
sales. Kensington crossed the £10 million threshold in 2001 with a £14 million transaction,
while Chelsea followed in 2004 with a £20 million sale. Momentum accelerated rapidly,
culminating in an £80 million sale in Kensington in 2015.
Today, the record still belongs to the borough: a £200 million sale on Rutland Gate in 2020
remains the highest residential transaction ever recorded in the UK.
What today’s discounts are telling us
Across Kensington, Chelsea, and the wider PCL market, average discounts from asking
price have followed similar long-term trends. However, discounts are currently higher than
historical norms, particularly across PCL, suggesting that while demand remains robust,
buyers are increasingly price-sensitive and willing to negotiate.
Scale matters
As the largest catchment within Prime Central London, Kensington and Chelsea naturally
generates greater total sales value. In 2022 alone, £1.9 billion was transacted across the
borough, compared with £707 million across the rest of PCL, underlining the area’s
continued liquidity and global appeal.
Looking back and ahead
Chris Cady, Managing Director at Marsh & Parsons, explains:
“To celebrate the union of these two historic boroughs 60 years ago, we wanted to look back
at how Kensington and Chelsea have compared with one another and how the combined
Royal Borough has performed relative to the rest of Prime Central London.”
With nearly 170 years of heritage rooted in Kensington, Marsh & Parsons has grown
alongside the borough itself from a single office on Kensington High Street in 1856 to a
network of more than 33 offices across the capital today.
Six decades on from the merger, one thing is clear: Kensington and Chelsea’s royal
marriage remains one of London’s most successful property partnerships.
