The top 10 postcodes to find a house share

More than 10,000 ads for rooms in E1 were listed on SpareRoom.co.uk between July and September, with prices ranging from £455-£1,049 a month.

Stretching form from Mile End to Aldgate and including the arty, foodie Zone 1 hotspots of Shoreditch and Whitechapel, it’s the London postcode with the highest number of rooms available to rent.

Rents are as varied in E14, which has the second-highest supply of available rooms in London.

Home to Canary Wharf and Docklands, the area is being transformed into a residential hub with thousands of new homes, new shops and schools, plus a high-speed Crossrail link due to open in 2018.

The supply to demand ratio is also lowest in these two areas of the capital, with fewer than five people searching for every room available in these postcodes.

“Those struggling to find rooms to rent in flat and house shares would be mad not to consider east London," says director of SpareRoom.co.uk Matt Hutchinson.

"Demand outstrips supply across London, so haggling on your rent is risky.

"But it’s certainly more of an option where supply is higher and demand is lower than elsewhere, such as E1.

"Good references from previous landlords will help, too."

Those hunting for house shares in north London will find the N1 postcode, which covers Angel, Islington and Canonbury, has the most rooms to offer, while Acton and Shepherd's Bush are the west London areas with the highest supply.
