Why Compare?
Most businesses overpay on their mobile contracts by 20 to 35 percent. The main reasons are auto renewed contracts at inflated rates, data plans that do not match actual usage, and hidden charges. Comparing all four networks side by side reveals whether you are getting good value or paying more than you need to.
| What We Check | Why It Matters |
|---|---|
| Coverage at your postcodes | The cheapest deal is useless with poor signal |
| Data vs actual usage | Right sizing prevents overpaying and overage charges |
| Contract terms | Length, price rises, exit fees all affect total cost |
| Multi line discounts | 5+ lines typically save 10 to 25 percent |
| Business features | Fleet management, MDM, roaming, support levels |
Frequently Asked Questions
How much do 5 line business mobile deals cost?
Five line business mobile deals start from around approximately £11+VAT per line per month for SIM only plans with modest data allowances. Unlimited data SIM only plans for five lines typically cost approximately £11+VAT to approximately £11+VAT per line. Handset deals with flagship phones start from around approximately £11+VAT to approximately £11+VAT per line per month. All prices exclude VAT.
Can I mix SIM only and handset deals across my 5 lines?
Yes. Most networks allow you to mix and match within the same account. For example, you could have three SIM only lines for staff who already have phones, and two lines with new handsets. All five appear on one bill and you still receive multi-line pricing.
Do I get a discount for ordering 5 business mobile lines?
Yes. Five lines is typically the threshold where networks start offering meaningful multi-line discounts. Through Compare The Networks, five-line bundles unlock per-line savings of 10 to 25 per cent compared to ordering individual contracts.
Can I manage all 5 lines from one account?
Yes. All five lines sit under a single business account with one monthly invoice. You get a centralised management portal where you can view usage, set data caps, add or remove lines, and manage your account. This is far simpler than having five separate contracts.
What happens if I need to add more lines later?
You can add additional lines to your account at any time during your contract. New lines are added at the same or better per-line rate. If you grow beyond 10 lines, you may qualify for even deeper volume discounts.
Is there an annual price increase on 5 line deals?
Yes. All major UK networks apply a fixed approximately £11+VAT plus VAT per line per month increase each April. On five lines, that is approximately £11+VAT plus VAT per month from the April after your contract starts. This is a fixed amount, not a percentage, so it is predictable and easy to budget for.
