If you dream of leaving behind your messy house share to live alone, you should be prepared to pay over £15,000 more a year in west London.

Shocking new figures researched by getwestlondon 's data team reveals splashing out on a one bedroom flat could cost you thousands more in rent.

While a room in a house share in Kensington and Chelsea costs an average of £823 a month, a one bed apartment in the borough will typically set you back £2,102 monthly.

Similarly, a one bedroom flat in Westminster costs £1,950 a month on average, compared to £845 a month for a room in a house share - or £13,260 more a year.

Even in boroughs not in Central London, it could cost over £5,000 a year extra to live alone

If you’re willing to compromise on space you might be able to manage a studio flat, although prices in London for these "one space" flats are astonishingly high.

A studio flat costs around £1,517 a month on average in Kensington and Chelsea and £1,408 a month in Westminster.

Even in the parts of west London where one bedroom flats are cheaper, the dream to live alone might still be a monumental financial task.

In Hillingdon borough, a room in a houseshare costs £450 a month on average, while a one bedroom flat is £900 a month - £5,400 more a year.

A spokesman for West London Housing association told getwestlondon: "A high demand in property in London from investors all across the world means there are people who will pay huge sums of money for one bedroom flats.

"In England as a whole, the gap is significant between house sharing and living alone, but in London, it is extortionate and for many, a long lost dream which remains unachievable."
