Top tips

Hiring a storage, without the regret.

Four moves that separate a smooth job from a nightmare.

Personal use vs business — different rates.

Personal storage units are cheaper than business contracts. Specify which on enquiry — business has VAT and SLA requirements.

Check insurance on the unit.

Most storage facilities offer optional insurance; many homeowner policies don't extend to off-site goods. Get cover one way or another.

Climate-controlled for sensitives.

Antiques, art, electronics, paper — these need climate-controlled units. Standard units swing 5–35°C and 40–90% humidity in a year.

24-hour access matters.

Some facilities are office-hours only. If you need evening or weekend access, confirm before signing.
