Question 1

What size storage unit do I need?

Accepted Answer

A 25 sq ft unit fits seasonal items or around 30 boxes. A 50 sq ft unit holds the contents of a one-bedroom flat. A 100 sq ft unit (about a single garage) holds a two- to three-bedroom house. A 200 sq ft unit suits a four- to five-bedroom home or commercial stock.

Question 2

How much does each storage unit size cost in the UK?

Accepted Answer

A 25 sq ft unit costs roughly £40–£100/month, a 50 sq ft unit £95–£160/month, a 100 sq ft unit £190–£320/month, and a 200 sq ft unit £285–£450/month. London prices are typically 30–50% higher.

Question 3

What if I'm between two sizes?

Accepted Answer

If you're unsure, size up. The cost difference between two adjacent sizes is usually small, and it's far cheaper than renting a second unit later. Facility staff can also advise on the day.
