Taxpayers in London fork out more than £12 billion every year to subsidise social housing in the capital, according to new data compiled from the ONS Price Index of Private Rents and Census figures. In certain parts of the capital, taxpayers pay £2,500 every month for a single social home to bridge the gap between market value and social rent, with the average taxpayer subsidy standing at £1,553 across London.
London Boroughs Facing the Largest Rent Gaps
The financial disparity between private and social rents is most pronounced in the wealthier boroughs of central London. Kensington and Chelsea leads the figures, where social housing is on average £2,592 cheaper per month than the private market rate. Westminster follows closely with an average monthly difference of £2,429, while Islington records a gap of £1,975 and Camden sees an average difference of £1,904.
In Camden, where Sir Keir Starmer was until recently the local MP, social housing tenants typically pay around £763 a month for a three-bedroom home. That amount is less than a third of the average £3,055 charged for the same house on the private market, leaving taxpayers to cover a monthly difference of £2,292. In several boroughs run by Labour, a tenant in social housing could receive a total subsidy of roughly £656,000 over 50 years, provided they stay in the same residence.
Did You Know? Based on 2021 census data, 47.6 per cent—just under half—of all lead tenants in London’s social housing were born abroad, whereas this figure was less than a fifth for England and Wales as a whole.
New Data Tool Highlights Market Disparities
The figures come from a new data tool created by Tory London Assembly Member Neil Garratt, marking what is believed to be the first time the two datasets have been combined to show the exact difference between social housing payments and market rents across the capital. Britons can now use the resource to calculate the average lifetime subsidy cost that council-controlled rents provide. Mr Garratt stated that the tool allows people to visualise how social housing fits into the housing market and view the astonishing gap between the going rate for a London flat and subsidised rents.
“That gap is covered by taxes on people who already have to pay for their own housing,” Mr Garratt said, adding that housing starts have collapsed under the current Mayor and that Londoners face rent taking up an ever-greater share of their salaries. John O’Connell, chief executive of the TaxPayers’ Alliance, responded that London taxpayers deserve to know the true cost of council rents set far below private market levels. He argued that while social housing supports people in genuine need, the discounts are not cost-free and councils should publish the full financial impact for transparency.
Government defends social housing sector amid £39 billion investment
A Ministry of Housing, Communities and Local Government spokesman defended the sector, stating that social housing helps hard-working families and lifts children out of poverty and homelessness. The government pointed to a £39 billion investment in social and affordable homes intended to tackle the housing crisis head-on and provide local people with stability. This data tool was developed to facilitate candid and open discussions between voters and council leaders regarding social housing subsidies, allowing politicians and the public to determine what level of subsidy is appropriate.
