Is off-site document storage cheaper than keeping records in the office?

For most businesses with more than 50 boxes, yes. Off-site storage costs 5p-25p per box per week. The equivalent office space, staff time, equipment and insurance costs typically add up to several times more.

How much can I save by switching from on-site to off-site storage?

A typical business with 150 boxes can save £5,000-£7,000 per year by switching to professional off-site storage. The exact saving depends on your office rent, staff costs and how often you need to retrieve documents.

Document Storage vs On-Site Storage: Which Is More Cost-Effective?

This is one of the most common questions businesses ask when their archive starts to outgrow their office space. The answer depends on several factors — but for most businesses storing more than 50 boxes, professional off-site storage is significantly cheaper than keeping records on-site.

Calculating Your On-Site Storage Cost

Most businesses have never calculated how much their on-site document storage actually costs because the expenses are spread across several budget lines. To make a fair comparison, you need to account for all of them:

Space Costs

Identify every area in your premises used for document storage — dedicated archive rooms, filing cabinet zones, under-desk storage, cupboards, basements. Calculate the floor area in square feet, then multiply by your cost per square foot per year (rent, rates, service charges).

UK office rents range from around £15/sq ft in regional locations to £60+/sq ft in central London. Even a modest 100 sq ft storage room costs £1,500-£6,000 per year before you put a single document in it.

Staff Costs

Consider how much time your team spends on document-related tasks: filing new documents, retrieving files when needed, returning files after use, organising and tidying the archive, managing retention and destruction. Research suggests office workers spend an average of 20-40 minutes per day on document handling. For a team of 10, that is 30+ hours per week — the equivalent of almost a full-time employee.

Equipment and Supplies

Filing cabinets (£150-£400 each), shelving units, archive boxes, labels, dividers and other supplies. These are one-off costs, but they add up — especially when your archive is growing and you need to keep purchasing more.

Insurance and Risk

Large volumes of paper increase your fire risk, which can affect your insurance premiums. You may also need fire extinguishers, detection systems or other safety measures in storage areas.

What Off-Site Storage Costs

Professional document storage is priced primarily on a per-box basis:

Storage — 5p to 25p per box per week (equivalent to £2.60-£13 per box per year)
Collection — a one-off charge for collecting your documents and bringing them to the facility
Retrievals — charged per request, typically £2-£8 per box depending on the provider and speed of service
Delivery — per trip, varies by provider and urgency

Side-by-Side Comparison

Here is a realistic comparison for a business with 150 archive boxes currently stored in two rooms and a corridor:

On-Site (Current)

Office space: £4,500/year (150 sq ft at £30/sq ft)
Staff time: £3,500/year (estimated 8 hours/week at £8.40/hour)
Equipment: £500/year (amortised)
Insurance uplift: £300/year
Total: approximately £8,800/year

Off-Site (Professional)

Storage: £1,170/year (150 boxes at 15p/week)
Initial collection: £250 (one-off)
Retrievals: £480/year (estimated 10 per month at £4 each)
Deliveries: £360/year (estimated 4 per month at £7.50 each)
Year 1 total: approximately £2,260
Year 2+ total: approximately £2,010/year

Annual saving: approximately £6,500-£6,800 — plus the freed-up office space can be reused.

When On-Site Storage Makes More Sense

Off-site storage is not the best option for every situation:

Very small archives — if you have fewer than 20-30 boxes, the collection charges and minimum fees may not be worthwhile
Constant daily access — if the same files are needed multiple times per day by multiple people, having them on-site is more practical. Consider scanning frequently used files instead
Active project files — current working files that are still being added to or modified regularly. These should stay on-site until they become archive material
You have genuinely free space — if you own your premises outright with spare rooms that have no alternative use, the space cost calculation changes

The Hybrid Approach

Many businesses find that a hybrid approach works best: keep active working files on-site for immediate access, and move closed or archived files off-site. This gives you the speed of on-site access for current work and the cost efficiency of off-site storage for everything else.
