Using a Storage Unit When Moving: When It Helps and What It Costs

When Storage Makes Sense During a Move

Not every move is a clean transfer from old property to new on the same day. Chains collapse. Completion dates shift. New builds overrun. Rental periods end before purchase completes. In all of these situations, a storage unit acts as a buffer — allowing you to vacate the old property on time without needing access to the new one.

Storage is also useful when there's simply a mismatch in size — if you're downsizing temporarily, or if the new home needs significant work before you move your belongings in.

This guide covers the scenarios where storage helps, how to choose the right facility, and what you'll actually pay.

Scenarios Where Storage Is Worth Considering

**Completion date uncertainty.** If your sale completes but your purchase is delayed — common in chains — you may need to vacate and store your belongings for days, weeks, or occasionally longer.

**Chain break and onward search.** If you're selling to move into rented accommodation while you continue your property search, you'll want to store the majority of your furniture rather than pay for furnished rental on top of your items being in a van.

**Downsizing.** Moving from a five-bedroom house to a three-bedroom property often means you can't take everything immediately. Storage gives you time to decide what to keep, sell, or donate without the pressure of moving day.

**Renovation work.** If the new property needs significant work — replastering, rewiring, new flooring — it's far more practical to have most of your belongings in storage until the work is complete.

**International moves.** If there's any international element to your move, particularly with shipping lead times, storage at the UK end is often necessary.

How to Choose a Storage Facility

Not all storage facilities are equal. The key factors to consider:

**Location.** Closer is cheaper in terms of your time and travel costs, but city-centre facilities are typically more expensive per square foot than those on industrial estates at the edge of town. Balance convenience against cost based on how often you'll need access.

**Security.** Look for 24/7 CCTV, individual unit alarms, controlled site access (key fob or PIN), and well-lit areas. Ask whether the facility has had any security incidents.

**Access hours.** Most self-storage facilities allow access during business hours and some allow 24/7 access. If you might need to retrieve items early in the morning or at weekends, check access hours before booking.

**Cleanliness and condition.** A good facility is dry, well-maintained, and pest-free. A site visit before booking is advisable — check for signs of damp on the ceilings or walls, and ask when the facility was last inspected.

**Unit size.** Storage is typically measured in square feet. A rough guide: 25–35 sq ft for a one-bedroom flat, 50–75 sq ft for a three-bedroom house, 100+ sq ft for a larger home. Staff at the facility should be able to advise based on what you need to store.

**Climate control.** Standard units are unheated. For most household items this is fine. Antique furniture, artwork, electrical equipment, wine, and musical instruments may benefit from climate-controlled storage, which is typically 20–30% more expensive.

**Insurance.** Most storage facilities require contents insurance. Some include cover in their price; others require you to arrange it separately. Check what is and isn't covered — flood, fire, and theft are standard; accidental damage and mechanical breakdown of electronics often aren't.

Storage Costs in 2026

Costs vary significantly by location, facility quality, and unit size. The following are typical 2026 figures for England, excluding London.

**Small unit (25 sq ft — one-bedroom flat):** £40–£80 per month

**Medium unit (50 sq ft — two to three-bedroom home):** £80–£150 per month

**Large unit (100 sq ft — four to five-bedroom home):** £150–£300 per month

**London and the South East** will be at the higher end of these ranges, typically 30–50% above the national average for comparable facilities.

Most facilities offer introductory discounts of 50% for the first four weeks. If you're booking in advance and know you'll be storing for at least two months, it's worth negotiating — particularly if the facility has capacity.

Ask about all fees upfront: administration charges, lock fees (some facilities require you to use their locks), and any penalties for early termination if your move completes sooner than expected.

Practical Tips for Using Storage

**Pack properly.** Items in storage can be there for longer than expected. Use good-quality double-wall boxes, wrap fragile items thoroughly, and label everything clearly. Photograph the contents of each box before sealing it.

**Stack vertically.** Put the heaviest, most robust items at the bottom and lighter, fragile items on top. Leave a walkway down the middle of the unit so you can access items at the back without unpacking everything.

**Wrap furniture.** Solid wood furniture can crack if left uncovered. Use furniture blankets or stretch wrap to protect surfaces.

**Don't store perishables.** Food, damp items, and anything that can rust, rot, or attract pests should not go into storage.

**Make a manifest.** Keep a written list of what's in each box and each part of the unit. When you need to retrieve a specific item at 8am before driving to the new property, you'll be glad you made one.

Storage is a cost worth building into your moving budget if there's any uncertainty in your timeline. The flexibility it provides often outweighs the monthly fee, particularly in a chain where delays are common.
