New research has found that the London Marathon route offers a snapshot of the capital’s rental market, with average rents ranging from just £1,500 per month at some points of the course, to as much as £6,000 per month in others.

Lettings and Estate Agency, Benham and Reeves, analysed current asking rents across the postcode districts that make up the 26.2-mile London Marathon route, from Blackheath to The Mall, to reveal how rental values vary across the capital.

The analysis shows that the average monthly rent across the marathon route currently stands at £2,916. However, while runners taking part in the race will cover 26.2 miles, they will pass through rental markets where the cost of living differs dramatically from one neighbourhood to the next.

The most affordable point on the route is found at miles four and five along Woolwich Road in the SE7 postcode, where the average asking rent currently stands at £1,500 per month.

The SE18 postcode around Charlton Park Lane and John Wilson Street, home to miles two and three, is the second most affordable stretch of the route, with an average monthly rent of £2,000.

 The highest rents are found at the closing stages of the race. Embankment at mile 25 commands an average rent of £4,000 per month, before the route reaches St James’s and The Mall in the SW1 postcode, where both mile 26 and the finish line average £6,000 per month.

Marc von Grundherr, Director of Benham and Reeves, said: “The London Marathon route is a perfect demonstration of the diversity of the London rental market.

“What this really shows is that London remains a market of huge choice, whether tenants are looking for affordability, riverside living, vibrant neighbourhoods or a prime central London address.”
