The latest data from the Office for National Statistics confirms what many parents already know: the cost-of-living crisis is forcing a record number of young professionals back into the family nest. The proportion of 20- to 34-year-olds living with their parents has hit 28 per cent, the highest level since records began in 1996. For graduates returning from university, this is no longer a temporary summer stopgap but an indefinite arrangement.
This is not about laziness or a failure to launch. It is simple arithmetic. Consider the numbers. Average graduate starting salary in London: £30,000. After tax, National Insurance, and student loan repayments that leaves roughly £1,800 a month. Median rent for a one-bedroom flat in Zone 2: £1,600. Add council tax, utilities, transport, and you are left with perhaps £50 a day for food and everything else. The numbers do not add up. They have not added up for years, but now with inflation at 6.8 per cent and mortgage rates at 5.5 per cent, the sums have become absurd.
This trend is fundamentally reshaping the housing market. With young professionals no longer forming new households, demand for rental properties in commuter zones has dropped, pushing down yields. Some landlords are selling up, which in theory should lower house prices. But this is the British housing market where logic often takes a holiday. The correction is happening in the rental sector, not in freehold values. The Bank of Mum and Dad, already a major force in home purchases, is now becoming the primary lender for the entire rental market. Parents are effectively subsidising the housing supply by providing rent-free accommodation to their adult children.
What does this mean for fiscal policy? The Treasury should be concerned. The OBR's projections for housing transactions and stamp duty revenues are now clearly too optimistic. More importantly, this generation is delaying family formation, which will have long-term implications for household formation, consumption patterns, and ultimately GDP growth. The housing market is not just a store of wealth it is a transmission mechanism for the entire economy. And right now, that mechanism is seized up.
The government's response so far has been the usual mix of tweaks to Help to Buy and calls for more construction. But the problem is not supply, or at least not only supply. It is affordability in the context of high inflation and stagnant real wages. Until that equation changes, the boomerang generation will keep coming home.
For investors, this is a warning signal. Residential property in the UK has been a one-way bet for decades, but the demographic winds are shifting. If young people cannot afford to move out, demand for family homes in the suburbs will decline. The premium on properties near good schools and commuter stations may evaporate. I would be looking at the data on household formation rates rather than listening to estate agents' optimism.
The bottom line: the cost-of-living crisis is not just a pain in the wallet; it is reshaping the very structure of British society. And until policymakers wake up to that reality, the boomerang generation will keep spinning back home.
