How much does self storage cost in the UK? A 2026 price guide by unit size
Self storage pricing varies so much between facilities that a single "average price" is more misleading than useful. What's more helpful is understanding the typical range for each common unit size, and the handful of factors that consistently explain why one facility charges more than another for what looks like the same box of space.
At the smaller end, a 25 sq ft unit — roughly the size of a small box room, enough for a few pieces of furniture and a run of boxes — commonly costs somewhere around £12 to £45 per week, with the low end typical of smaller towns and the upper end more common in cities and premium facilities. Stepping up, a 50 sq ft unit, often described as suiting a one-bedroom flat's worth of belongings, commonly runs around £20 to £40 per week. A 75 sq ft unit, generally the go-to size for the contents of an average two-bedroom house, is commonly priced around £22 to £35 per week, or roughly £95 to £150 a month. At the larger end, a 100 sq ft unit, closer to a single garage's worth of space, commonly costs around £35 to £55 per week.
Location is consistently the single biggest driver of where a facility sits within these ranges. London and other major cities sit reliably at the top end, with some London pricing cited around £3.67 per square foot — a multiple of what the same size unit might cost in a smaller town or a facility on the edge of a city rather than in the centre. This isn't unique to storage; it reflects the same land and demand pressures that push up rent and retail space in general, and it's worth bearing in mind when comparing a city-centre facility against one a short drive further out.
Beyond location, several other factors commonly move the price for a given size: how much demand there is locally relative to available space, the length of contract or any minimum term, and whether the unit is indoor and climate-controlled or an outdoor container-based unit — indoor space commonly carries a premium over container storage for a comparable size, reflecting the added security and environmental protection. Facilities also frequently run promotional rates for new customers or longer bookings, which can make an initial quote look considerably lower than the ongoing rate, so it's worth asking specifically what the price will be after any introductory period ends.
Because of how much these factors move the final number, the only genuinely reliable way to budget for self storage is to get quotes from two or three local facilities for the specific size and access type needed, rather than anchoring on a single figure found online. It's also worth asking directly whether the quoted price includes insurance, since — as covered in more detail elsewhere — most facilities require insurance as a condition of the rental agreement, and this can add a meaningful amount on top of the headline weekly rate.
Frequently asked questions
A 25 sq ft unit commonly costs around £12 to £45 per week and a 50 sq ft unit, often suited to a one-bedroom flat, commonly runs around £20 to £40 per week, with the exact price depending heavily on location and facility.
Higher demand for space relative to supply pushes city pricing up considerably, with some London storage cited around £3.67 per square foot — a multiple of typical pricing in smaller towns or facilities further from city centres.
Generally yes for a comparable size, since indoor climate-controlled units commonly carry a price premium reflecting the added security and environmental protection, while container storage tends to offer better value per square foot.
Not always — it's worth checking directly, since most UK facilities require insurance as a condition of renting, and this is commonly charged on top of the headline weekly or monthly unit price.
