UK tenants face the highest rents in western Europe, with Birmingham one of four UK cities in the top 10 of most expensive cities in which to rent a room, research has showed.
It costs an average of £348 a month to rent a room in a shared property in the UK, 75% more than in Spain, where rents average just £199 a month, according to flatshare website Easyroommate.co.uk.
France was the second most expensive country in which to rent a room, but at an average of £285 a month rents were still considerably cheaper than in the UK, while in Italy they averaged £282 a month.
But despite the UK having the highest average rents, the most expensive city in which to rent a room was Milan in Italy, at a typical cost of £621 a month.
London was the second most expensive place at an average of £551 a month, followed by Rome at £441, Paris at £426 and Nice at £380.
Birmingham, Manchester and Leeds also made it into the list of the top 10 most expensive cities in which to rent a room.
The group blamed the high cost of renting a room in the UK on the lack of mortgage finance currently available, which it said was forcing potential first-time buyers to continue renting, driving up demand.
Jonathan Moore, director of Easyroommate.co.uk, said: "The rent is far higher for British flatsharers than it is for their European counterparts. The strength of the pound against the euro plays a part - but that's not the whole story.
"Brits are paying more for their accommodation because frustrated first-time buyers are pushing up demand for rental properties."
Valencia in Spain is the cheapest place to rent, at an average cost of £207 a month, with Seville and Zaragoza, also in Spain, both also featuring in the top five cheapest cities for renters.
