New analysis has suggested that close to four in ten homes built in the UK by 2030 may be required to house migrants. The figures have sparked debate over how migration could affect the country’s housing supply and the availability of homes for existing residents.
Research carried out by the Conservative Party, using projections from the Office for Budget Responsibility’s latest Economic and Fiscal Outlook, points to the potential pressure that future migration could place on Britain’s housing stock. According to the watchdog’s forecast, net migration between 2026 and 2030 could reach around 1.17 million people.
Using the average household size calculated by the Office for National Statistics, analysts estimate that roughly 499,000 additional homes would be required simply to accommodate new arrivals during that period.
At the same time, housing projections suggest that around 1.34 million new homes could be built across the UK over the next five years. If those projections hold true, around 37% of new housing supply during that time may be used to house migrants. By 2030, the figure could rise slightly to about 39%.
These estimates highlight how population growth may influence the demand for housing in the coming years. As the number of residents increases, the need for additional housing naturally grows, placing greater pressure on both new developments and the existing housing market.
Some politicians argue that higher migration levels could contribute to rising house prices and rents. Government data cited in the analysis suggests that increased demand linked to migration could add around £9,489 to the average property price.
Shadow Home Secretary Chris Philp said the figures demonstrate that immigration levels can have direct effects on housing availability and affordability. He argued that without careful planning, rising demand may make it harder for some people to access new homes.
Similarly, Shadow Housing Secretary Sir James Cleverly stated that even if the government increases housebuilding, a significant portion of those homes could be needed to meet housing demand created by migration. According to him, this situation contributes to the challenges many young people face when trying to enter the housing market.
Both politicians have suggested policy changes aimed at reducing housing pressures, including measures designed to control migration and increase housing availability.
However, the government has defended its housing strategy and pointed to plans aimed at addressing the broader housing shortage. A spokesperson said the government is working to deliver around 1.5 million new homes while also tackling the housing crisis that has developed over many years.
Officials also highlighted ongoing efforts to reform the UK’s migration system. According to government figures, net migration has already begun to decline significantly in recent years, following policy changes intended to manage the overall numbers.
The government argues that increasing housebuilding remains a key part of its plan to improve access to home ownership and stabilise the housing market.
The discussion highlights the complex relationship between population growth, migration and housing supply. As demand for homes continues to rise, policymakers are facing growing pressure to balance housebuilding targets with broader economic and social factors.
For many analysts, the central challenge remains clear: ensuring the UK builds enough homes to support both existing residents and future population growth while maintaining affordability across the housing market.
Debates around migration and housing demand are likely to continue as new data emerges and the government works towards its long-term housing targets for the end of the decade.
