As the number of people renting in the UK continues to rise, the BBC has taken a closer look at the state of private renting. The typical one-bed home in England costs \u00a3600 a month to rent, but this is skewed by soaring costs in London and hides a gaping divide across the country. In parts of Westminster, the average one-bed costs more than \u00a33,500 per month. In Argyll and Bute, that sum could cover your rent for a whole year. 1. More rooms? Move city Let\u2019s say you lived in a three-person house-share in SW4, Brixton, London. According to Hometrack, you could expect to pay around \u00a3767 per month, along with your two flatmates. With that money, you could comfortably rent a one-bedroom flat in Southend or Milton Keynes \u2013 both within commuting distance of the capital \u2013 all to yourself. In fact, you\u2019d be able to rent a one-bedroom flat in 79% of British postcodes, including locations such as Bristol. \tTwo-thirds of rental market \u2018unaffordable\u2019 for young people \tIs renting cheaper in the next beighnourhood? If you wanted a bit more space, you could get a two-bedroom home in 65% of Britain\u2019s postcodes for \u00a3767 or less. You could live in L1, in the heart of Liverpool, where rents for a two-bed property are around \u00a3751. For the same rent or less, you could also get a three-bedroom property in Leeds (LS8) with money to spare. Or, if Leeds isn\u2019t for you, around 50% of all British postcode areas have an average price of \u00a3767 or lower for a three-bed. If you\u2019re in particular need of space, for the same price as a room in a Brixton flat-share, you can rent an entire four-bed property to yourself in 410 postcode districts across the country \u2013 including in cities such as Birmingham, Newcastle and Swansea and Glasgow. 2. Who\u2019s renting? Private renting has more than doubled over the past 20 years, and young people are by far the most likely age group to be renting. During the same period, home ownership among young adults has collapsed. In 1995-96, some 65% of middle-income 25 to 34-year-olds owned a home. Twenty years on just 27% do, with the biggest drop in London and south-east England. 3. Renters pay a premium for isolation Renting a one-bedroom flat in England costs \u00a3600, yet buddy up with someone, and your share drops to \u00a3325. Find two flatmates, and you can get away with paying just \u00a3250 for a room in a three-bed home \u2013 less than half the cost of a one-bed flat. This will be no mystery to renters in cities such as London, where for many young people, flat-sharing is the only option. In the capital, the average one-bed costs \u00a31,237, but a third of a three-bed property costs \u00a3582 on average, saving you more than \u00a3650 each month. 4. Four regions are \u2018unaffordable\u2019 Working out what proportion rent makes up of your salary is a good measure of how affordable it is. Housing organisations recommend spending no more than 30% of your income on housing costs. While Londoners earn more than residents of other regions, the city\u2019s rental properties still make up a bigger chunk of residents\u2019 salaries than renters in other areas. For example, renting just a one-bed flat in the capital eats up nearly half of the average salary. Compare rent affordability in your area with Britain as a whole Housing organisations recommend spending no more than 30% of your salary on rent. The average rent of a 1-bedroom home exceeds this for twenty-somethings in two-thirds of Britain. 5. Cambridgeshire rents rising the most It will come as no surprise to anyone that London\u2019s rental market is the priciest. But rents have actually risen by more elsewhere in the country. The median rent for a one-bedroom flat in the East of England rose from \u00a3495 in 2012-13, to \u00a3650 in 2017-18, according to official figures. That\u2019s an increase of almost a third. In particular, rents in Cambridgeshire rose by two-thirds in that period, from \u00a3450 to \u00a3750 a month. Other big increases were found in Barking and Dagenham, Bristol, and Greenwich, where prices rose 40% or more. We don\u2019t have local authority data for the other nations, but we do know that across England, there were only eight local authorities where one-bed rents fell. Three were in the North West, four in the North East, and, perhaps surprisingly, Kensington and Chelsea in London. 6. London has huge rent inequality Even within large cities, you might still find rents that are less eye-watering if you look in the right place. The data reveals the importance of location in determining how high your rent is likely to be. The cheapest corner of London\u2019s postcode area (SE2, in Greenwich) is more expensive than the priciest areas of most of the country\u2019s major cities. However, the number of areas with extremely expensive rents means that it still has the biggest price gap. To rent a one-bed flat in three London postcodes \u2013 SW1X, W1J and EC2R \u2013 you\u2019d need to fork out more than \u00a33,000 every month. But there are still three London postcodes \u2013 SE2, SE28, SE9 \u2013 where you can rent a one-bed for less than \u00a31,000.

This means they\u2019d pay a rent, service charge, and a mortgage on the bit they own (which usually ranges from 35% to 75%). These costs add up, but not \u2013 as it turns out \u2013 more than renting. We looked at the total costs of all the shared ownership listings within a five-mile radius of central London, and matched them up to the equivalent rent for that postcode. Two-thirds of the shared ownership properties were actually cheaper than renting in that area. But don\u2019t get excited that shared ownership is affordable in London \u2013 the average shared ownership home listed still takes up almost 70% of young Londoners\u2019 incomes.
