How Much Should a Business Mobile Contract Cost in 2026?

How much should a business mobile contract cost per month in the UK in 2026? Real benchmark ranges for SIM-only, unlimited data and handset deals.

In 2026, a UK business mobile line typically costs about £8–£18 per month for SIM-only, £15–£30 for unlimited data, and £25–£60+ when a handset is included. What you actually pay depends on data, number of lines, contract length and whether you bring your own phones. This guide gives realistic benchmark ranges so you can sanity-check a quote and spot when you are overpaying.

Benchmark monthly costs per line

What moves the price

Five things drive your cost: data allowance (the biggest lever after hardware), whether a handset is included, the number of lines (volume usually earns better per-line rates), contract length (longer terms lower the monthly), and add-ons like international roaming or device insurance. Business tariffs also typically include better support, pooled data options and VAT-reclaimable invoicing that consumer plans do not.

Signs you’re overpaying

• Paying for unlimited data when usage data shows most lines use under 20GB.
• Still paying handset-inclusive rates after the device is paid off (a “phantom” cost).
• No pooled data, so some lines waste allowance while others overspend.
• Per-line rates that haven’t been renegotiated in two or more years.

How to get the best rate

Right-size data to actual usage, pool data across lines, go SIM-only where staff already have phones, and review at renewal rather than rolling on. Comparing across networks at renewal typically yields the biggest saving — the same usage can vary widely between EE, Vodafone, O2 and Three.

Best-for picks

• Lowest cost: SIM-only, right-sized data, longer term.
• Heavy data users: unlimited SIM-only, pooled where possible.
• Need new devices: mid-range handset deal beats flagship on value.

Frequently Asked Questions

How much does a business mobile contract cost per month?

Roughly £8–£18 per line for SIM-only, £15–£30 for unlimited data, and £25–£60+ with a handset included, depending on data, volume and term.

Is business mobile cheaper than personal?

Per line it can be similar or cheaper, especially SIM-only, and business plans add pooled data, better support and VAT-reclaimable billing that consumer plans lack.

How much is unlimited data for business?

Typically £15–£30 per line per month, lower with volume. It is only worth it for genuinely heavy users or those hotspotting regularly.

Do more lines reduce the price per line?

Usually yes. Volume and pooled data often unlock better per-line rates, which is why fleets pay less per connection than single lines.

Does contract length affect cost?

Yes. Longer terms (24–36 months) lower the monthly but increase commitment. Rolling plans cost more per month for flexibility.

What’s the cheapest way to run business mobiles?

SIM-only with right-sized, pooled data on phones you already own is the lowest-cost approach.

Are there hidden costs to watch for?

Out-of-bundle charges, roaming, device insurance and continuing to pay handset-inclusive rates after the device is paid off are the common culprits.

Is business mobile VAT reclaimable?

VAT-registered businesses can generally reclaim VAT on business mobile costs. Confirm specifics with your accountant.

How often should I review my mobile costs?

At every renewal, and ideally annually. Usage and market rates change, and unreviewed accounts tend to drift to poor value.

Can I lower costs without changing network?

Sometimes, by right-sizing data and pooling, but the biggest savings usually come from comparing across networks at renewal.

What’s a fair price for a flagship phone on business?

Flagship-inclusive lines commonly run £45–£60+ per month. A mid-range device delivers far better value if budget matters.
