New research from bridging loans broker Octagon Capital reveals the cities in the UK getting the worst deals on self-storage units, with Londoners paying significantly over the odds at a rate 107% higher than the national average.

Looking at the average cost of a 50 sq. ft. unit in locations around the country (ideal for storing the contents of a one bedroom flat), London is the most expensive, with customers likely to spend an average of £1,797 per year.

Considerably higher than second place Swansea, which has an average of £1,006 per year for the same sized unit. Exeter residents are getting the best deal in the country, paying 31% less than the nationwide average (£598 p/y).

This trend continues when looking at 75 and 100 sq. ft. sized units, ideal for a two-bed flat or house, with London topping both tables and costs averaging 110% and 100% more than the average respectively. Liverpool similarly finds itself at the top end of the table for each unit size analysed, paying 12% more than average for 75 sq. ft. (£1,238 p/y) and 17% more for 100 sq. ft. (£1,674 p/y).

Camden in London has the highest individual costs per year for 75 sq. ft. and 100 sq. ft. units (£3,542 and £5,285 p/y respectively), while also placing second for 50 sq. ft. (£2,909 p/y) behind Kennington (£3,024 p/y).

Even when taking into account the average weekly wage in areas around the country, Londoners are still paying over the odds. For example, a 100 sq. ft. storage unit costs 8% of the average weekly wage of a Londoner, compared to just 3% of Portsmouth residents at the other end of the table. On average, 5% of the weekly wage would be spent on a storage unit of this size.
