How much is a storage unit per month in the UK?

The average cost for a 50 sq ft storage unit (suitable for a 1-bed flat) is around £80 to £120 per month. A 100 sq ft unit (for a 2-3 bed house) typically costs between £150 and £250 per month.

Are there any hidden costs in self-storage?

Yes. You must factor in mandatory insurance (often £10-£25/month), the cost of a high-quality padlock, and potentially a one-off administration fee.

Do I need insurance for self-storage?

What size storage unit do I need for a 3-bedroom house?

A 3-bedroom house usually requires a 150 sq ft to 200 sq ft unit. If you are a minimalist or have sold a lot of furniture, you might squeeze into a 125 sq ft unit.

Is indoor storage better than container storage?

Indoor storage (purpose-built facilities) is climate-controlled and better for delicate items like electronics and antiques. Container storage (outdoor) is usually 20-30% cheaper and great for robust items like garden furniture and tools.
