While London lays claim to the highest average rent being paid by tenants, it isn’t home to the priciest rental postcode, research reveals.

That accolade goes to Buckinghamshire’s HP9 postcode where tenants face an average monthly rent of £5,920.

According to a study by Cohab, a property management platform, this figure dwarfs the South East’s regional average of £1,562 by 279.1%.

It also soars 358.4% above the national average, marking it as Britain’s most expensive rental postcode.

Average renting costs

The firm’s founder and chief executive, Saveli Kotz, said: “While the cost of renting varies across Britain, each region is home to a prime postcode where rents sit significantly higher than that paid by the average tenant.

“In Buckinghamshire, for example, it costs nearly three times as much to rent than the South East of England, demonstrating how competitive it is for renters.

“It’s somewhat surprising that even the UK’s prime postcodes in central London, which are popular with international renters, don’t match up to the area.”

He added: “At the other end of the spectrum, Wales has the smallest difference between the average rental price and the most expensive postcode, suggesting tenant demand is more equally distributed in the country.”

Swansea is the cheapest

London takes second place with the SW7 postcode, which encompasses areas like South Kensington and commands £5,438 per month – 149.9% more than Greater London’s £2,176 average.

Elsewhere, Cornwall’s TR11 postcode leads the South West with rents averaging £2,834, a 124.8% premium over the region’s norm.

In the North West, Manchester’s M14 postcode, while more affordable at £2,280 monthly, demands a 126.6% markup compared to the regional average.

However, Swansea’s SA2 postcode, the most expensive in Wales at £1,510 per month, shows the smallest regional premium at 61.5% above Wales’ £935 average.
