A new report has quantified a phenomenon long familiar to anyone who has stepped inside a suburban self-storage unit: British households are spending billions of pounds annually to warehouse possessions they rarely use. The study, commissioned by the consumer group Sort Your Life Out, estimates that the average family pays £1,200 a year in storage costs, a figure that has risen sharply over the past decade amid a boom in personal storage facilities.
The numbers are stark. With more than 1,500 self-storage centres across the UK, the industry now turns over an estimated £2.8 billion annually. The report argues that this is symptomatic of a broader cultural shift towards accumulation, driven by online shopping and an attachment to material goods that outlasts their utility. “We have become a nation of hoarders,” said Dr. Eleanor Marsh, the study’s lead author. “The convenience of buying, combined with the emotional difficulty of discarding, has led to an unsustainable storage economy.”
The financial implications extend beyond direct storage fees. The report calculates that the average household spends an additional £400 a year on replacement items lost among the clutter, and a further £300 on moving and reorganising belongings. The opportunity cost is also significant: money spent on storage could instead be directed towards savings, investments, or experiences.
The findings have prompted calls for a national decluttering initiative, with critics pointing to the environmental impact of manufacturing and eventually disposing of unused goods. The storage industry, however, defends its role. “We provide a service that people need,” said a spokesperson for the Self Storage Association UK. “Many customers are storing items during life transitions, such as moving house or caring for elderly relatives.”
The report comes as the government considers tighter regulation of the sector, which has grown with little oversight. Consumer groups have long complained about hidden fees, automatic contract renewals, and aggressive debt collection practices. The Sort Your Life Out campaign recommends that families conduct a “storage audit” to assess the true cost of keeping unused items, and to consider how much they are paying per square metre for space they rarely visit.
The broader economic message is clear: in a country where housing costs continue to rise, paying to store things you don’t use is a luxury few can afford.
