The single biggest question we get from UK business buyers is “what should I actually be paying per line for our fleet?” — and the honest answer depends almost entirely on how many lines you have. Pricing for 5 lines is a different conversation to pricing for 50, and pricing for 100+ is a custom quote every time. This guide breaks down the real 2026 pricing tiers used by UK networks and specialist B2B resellers, with worked examples at each fleet size.

Why Fleet Pricing Drops Sharply Above 10 Lines
Network business teams price in tiers because of how their internal cost models work. Each line carries a fixed acquisition and provisioning cost (credit check, SIM logistics, billing setup, account manager time). Spreading those fixed costs across 5 lines is roughly twice as expensive per line as spreading them across 50.
The other driver is commercial value. A 50-line account is worth £4–£6k a year to the network and can support a dedicated business account manager. A 5-line account isn’t, and gets handled in self-service portals. Networks reflect that in pricing.
The breakpoints are reasonably consistent across EE, O2, Three and Vodafone:
- 1–4 lines: Standard SME pricing (often the same per-line as a single-line plan).
- 5–9 lines: First volume discount tier. Roughly 10–15% off list.
- 10–24 lines: Second tier. Discount widens to 15–25%.
- 25–99 lines: Mid-market pricing with custom add-ons (pooled data, bespoke roaming).
- 100+ lines: Enterprise pricing — bespoke contracts, custom MDM, dedicated account team.
Tier 1: 5–9 Lines (Small Business)
This is where most owner-managed UK SMEs sit — a director, an office manager, two or three field staff and a salesperson. Pricing here is the most variable across providers because the volume discount is small and most of the cost is the line itself.
Realistic May 2026 Pricing (5–9 Lines)
| Setup | Per-line monthly cost (ex-VAT) | Total monthly (5 lines) |
|---|---|---|
| SIM-only, 25 GB shared | £10–£12 | £50–£60 |
| SIM-only, unlimited per line | £14–£18 | £70–£90 |
| SIM + mid-range handset (Galaxy A56 / Pixel 9a) | £24–£28 | £120–£140 |
| SIM + flagship (iPhone 17 / Galaxy S25) | £42–£50 | £210–£250 |
All figures ex-VAT, 24-month terms, assume director’s guarantee not required (established Ltd).
Where the Money Hides
For a 5–9 line fleet, the single biggest avoidable cost is orphaned excess data charges. If one user repeatedly blows through their personal allowance and the others don’t, you’re paying excess on top of unused inventory. The fix is a shared “pooled” data plan — most networks offer pooling from line 5 onwards.
The second biggest cost is international roaming billed per-line rather than pooled. If you have any overseas trade, ask for a roaming pool included in the plan rather than a daily £2–£6 add-on.
Best Strategy at This Tier
Get three quotes — one direct from the network you currently use, one from a specialist business reseller (we’d say us, but the principle is the same) and one from a second network. The price gap between them at this tier is usually 12–20%. The friction of switching is also at its lowest at this tier (no MDM tooling to migrate, simple SIM swap).
Tier 2: 10–24 Lines (Established SME)
At 10+ lines, the volume discount becomes meaningful and you start to qualify for proper account management. This is also where shared/pooled data plans almost always beat per-line allowances on Total Cost of Ownership.
Realistic May 2026 Pricing (10–24 Lines)
| Setup | Per-line monthly cost (ex-VAT) | Total monthly (15 lines) |
|---|---|---|
| SIM-only, pooled data (300 GB shared) | £8–£11 | £120–£165 |
| SIM-only, unlimited per line | £12–£15 | £180–£225 |
| Mixed handset fleet (mid + flagship) | £28–£38 | £420–£570 |
| All-flagship fleet (iPhone 17 / S25) | £40–£48 | £600–£720 |
Pooled data plans typically deliver 20–30% lower TCO at this tier than per-line allowances.
What Else You Get at This Tier
- Named UK account manager (response SLA, single point of contact).
- Consolidated billing with cost centre tags — useful for charging back to teams or projects.
- Lite MDM — basic mobile device management included or available at low cost.
- 4-hour swap-out for damaged or faulty handsets in major UK cities.
Where the Money Hides
The hidden cost at 10–24 lines is contract drift. As staff change, lines get added at standard tariff rather than your negotiated tier, and you end up with a Frankenfleet of pricing. Annual contract reviews typically claw back 8–12% just by rebaselining everything to current pricing.
Best Strategy at This Tier
Go for a 24-month aggregated business contract with pooled data and a single account manager. Insist on quarterly bill reviews and a defined “line addition” pricing schedule so new starters don’t get bolted on at higher rates.
Tier 3: 25–99 Lines (Mid-Market)
At 25+ lines, you’re in mid-market territory. Pricing becomes genuinely bespoke — networks send you a Statement of Work, not a tariff card. The headline per-line cost continues to fall, but the bigger savings are now in bundled services: MDM, mobile threat defence, lifecycle management, eSIM provisioning.
Realistic May 2026 Pricing (25–99 Lines)
| Setup | Per-line monthly cost (ex-VAT) | Total monthly (50 lines) |
|---|---|---|
| SIM-only, pooled (1 TB shared) | £7–£10 | £350–£500 |
| SIM-only, unlimited per line | £10–£13 | £500–£650 |
| Mixed handset fleet | £26–£35 | £1,300–£1,750 |
| All-flagship fleet | £38–£45 | £1,900–£2,250 |
Add £2–£4/line for managed MDM (Microsoft Intune, Jamf or Samsung Knox Mobile Enterprise).
What Else You Get at This Tier
- Dedicated business account team (account director, technical lead, billing analyst).
- Custom roaming bundles — usually pooled GB across the fleet rather than per-line.
- Quarterly business reviews with usage analytics, recommendations and benchmark data.
- Hardware leasing options separate from airtime, useful for capital-allowance optimisation.
- White-glove onboarding — pre-provisioned, MDM-enrolled handsets shipped direct to staff.
Where the Money Hides
The hidden cost at 25–99 lines is under-utilised data plans. Networks happily sell you 5 GB per line per month. Reality check: most UK office workers use under 8 GB/month combined across mobile and Wi-Fi-on-mobile usage. If you’re paying for 250 GB across 50 lines and using 90 GB, that’s £80–£140/month wasted.
The fix is annual right-sizing based on actual usage data — something a competent specialist reseller does as part of the quarterly review.
Best Strategy at This Tier
Run a structured RFP every 24 months. Include the current network, two competitors and at least one specialist B2B reseller. Score on per-line cost, MDM included, account team responsiveness, and exit terms. Don’t be seduced by bundled “free” services that aren’t useful — they always come back as renegotiation leverage.
Tier 4: 100+ Lines (Enterprise)
Above 100 lines, every contract is bespoke. Per-line pricing falls to £6–£9 for SIM-only and £30–£40 for handset-included, but the negotiation moves from price to commercial terms: SLAs, exit clauses, rate cards for line additions/removals, and indemnities.
What Drives Enterprise Pricing in 2026
- Profile of usage — heavy data users in field roles cost more to serve than office-based 5G office desk warriors.
- Geographic spread — a fleet concentrated in London is cheaper to serve than one spread across rural UK + overseas.
- Handset refresh cadence — committing to a 3-year refresh cycle vs 2-year cuts per-line cost by 8–12%.
- Existing relationships — enterprise deals usually bundle MPLS/SD-WAN, hosted voice or fixed connectivity.
Realistic May 2026 Pricing (100+ Lines)
| Setup | Per-line monthly cost (ex-VAT) | Total monthly (200 lines) |
|---|---|---|
| SIM-only, fully pooled | £6–£9 | £1,200–£1,800 |
| Managed handset fleet (mixed) | £24–£32 | £4,800–£6,400 |
| Managed flagship fleet | £35–£42 | £7,000–£8,400 |
Enterprise contracts also include bespoke MDM, dedicated account team and 4-hour SLA — expect to add £3–£6/line for those bundled services.
Direct Network vs Specialist B2B Reseller — Pricing Comparison
A common question: should you go direct to EE, O2, Vodafone or Three, or use a specialist business reseller like Connection Technologies, Onecom, Vorboss or Daisy?
The honest answer is that for fleets of 5–100 lines, specialist resellers typically beat direct pricing by 8–15%. Three reasons:
- Wholesale pricing — resellers buy at wholesale rates and pass some discount on. Networks can’t undercut their own resellers without channel conflict.
- Multi-network leverage — a reseller can credibly threaten to move you to a different network at renewal. A direct customer is a captive renewal.
- Lower cost-to-serve — resellers are typically more efficient at SME/mid-market account management than the equivalent direct teams.
Above 200 lines, the picture shifts — networks have dedicated enterprise teams competing hard for those accounts, and direct pricing can be competitive or better. But the reseller advantage on flexibility and multi-network sourcing usually still applies.
Real Worked Example: 35-Line Fleet, Mixed Use
Imagine a UK construction services SME with 35 mobile lines: 10 office-based admin staff (low data), 20 site staff (medium data, occasional roaming), 5 directors (heavy data, regular roaming).
Direct Network Quote (illustrative)
- 20 × site staff @ £12/mo unlimited UK = £240
- 10 × office @ £8/mo (5 GB pooled = 50 GB) = £80
- 5 × director @ £18/mo (unlimited + roaming) = £90
- Total airtime: £410/mo
- + 25 mid-range handsets @ £14/mo over 24 = £350
- + 5 flagship handsets @ £25/mo over 24 = £125
- + 5 office BYOD = £0
- Total handsets: £475/mo
- All-in: £885/mo (~£25/line/mo)
Specialist Reseller Quote (typical)
- 35 lines on aggregate plan, 1 TB pooled UK + 60 GB pooled roaming = £350/mo airtime
- 25 mid-range handsets bundled @ £12/mo = £300/mo
- 5 flagship handsets bundled @ £22/mo = £110/mo
- 5 office BYOD = £0
- Lite MDM included
- All-in: £760/mo (~£21.70/line/mo)
Annual saving: ~£1,500 + better data flexibility + included MDM. That’s a representative scenario — actual quotes vary by network choice and current promotions.
Six Questions to Ask Any Fleet Quote
- Is the data pooled or per-line? Pooled almost always wins for fleets of 8+.
- What’s the rate card for adding a line mid-contract? Make sure new starters don’t get bolted on at premium rates.
- What’s the early-termination charge if I cancel a line within minimum term? Standard is “remaining contract value” — negotiate to a percentage.
- Is there an annual mid-contract price rise? Since Ofcom’s 2025 ban on inflation-linked rises, networks now use fixed-£ annual increases. Get the figure in writing.
- What MDM is included or available, and at what cost? Microsoft Intune, Jamf or Knox Mobile Enterprise should be in scope by 25 lines.
- What’s the SLA on faulty handset replacement? 4-hour swap-out in major cities is the standard for 25+ line fleets.
Common Fleet-Pricing Mistakes
Buying Inflated Plans “Just in Case”
Most UK business mobile users consume 4–8 GB/month. Buying 50 GB per line “in case someone hot-spots” wastes £4–£8/line/month. Use actual usage data from the prior 12 months as your baseline.
Ignoring the Cost of Switching
Switching all 50 lines to a different network has real costs: MDM re-provisioning, staff downtime, billing system changes, security re-policy. Factor in £20–£50 per line of internal switching cost when comparing offers.
Renewing Without Tendering
The single biggest cost mistake on fleet contracts is rolling renewal. Always tender — even if you stay with the same provider, the threat of leaving usually unlocks 8–15%.
Mixing Personal and Business Lines
Allowing staff to bring personal phones onto the business plan dilutes the volume discount and creates VAT-reclaim complications. Keep personal and business lines on separate accounts.
Recommended Next Steps for Each Tier
- 5–9 lines: Get 3 quotes (current network, one competitor, one specialist reseller). Decide on cost + flexibility.
- 10–24 lines: Tender for a 24-month aggregated business contract with pooled data and a named account manager.
- 25–99 lines: Run a structured RFP with at least 4 bidders. Score on TCO, MDM included, SLA and exit terms.
- 100+ lines: Engage an independent telecoms procurement consultant or specialist reseller to design the RFP and benchmark bids.

Frequently Asked Questions
For 10 lines on a SIM-only pooled-data plan, expect £8–£11 per line per month ex-VAT in May 2026. With mid-range handsets bundled, the per-line cost rises to £25–£30. With flagship handsets (iPhone 17 / Galaxy S25), it’s £40–£48 per line. Specialist business resellers typically come in at the lower end of these ranges.
For 50 lines on SIM-only pooled-data plans, expect £7–£10 per line per month ex-VAT. A managed handset fleet (mixed mid-range and flagship) typically costs £26–£35 per line. At this tier, contracts include a dedicated UK account team, quarterly business reviews and usually some bundled MDM. Custom roaming bundles and pooled data make a significant difference to TCO.
For fleets of 5–100 lines, specialist business mobile resellers typically beat direct network pricing by 8–15%. They buy at wholesale rates, can credibly threaten to move you between networks at renewal, and have lower cost-to-serve than direct SME teams. Above 200 lines, direct enterprise teams compete hard and pricing becomes more comparable.
Pooled data shares a single allowance across all lines on the contract — for example, 300 GB shared across 15 lines instead of 20 GB each. It’s almost always cheaper than per-line allowances above 8 lines because real-world usage is uneven, and pooled plans avoid paying for unused inventory while one user blows past their personal limit. Most UK networks offer pooling from 5 lines upwards.
Every 24 months is the right cadence for fleets of 10–99 lines. Renewing without tendering typically costs you 8–15% versus a competitive process — even if you stay with the same network, the threat of leaving usually unlocks better pricing. For 100+ line fleets, consider 36-month deals with built-in mid-term reviews to avoid disruption.
Yes. Bundled handset discounts kick in around 10 lines and widen at 25 and 100. A flagship handset bundled into a 50-line contract typically costs 15–25% less per month than the same phone on a single-line consumer plan. Specialist resellers often bundle handsets at lower margins than direct networks because they’re competing on TCO not headline tariff.
