Why Compare?

Frequently Asked Questions
How can I reduce my business mobile costs?
The most effective ways to reduce business mobile costs are: audit your current spend to identify waste, switch to SIM only deals if staff already have phones, consolidate all lines under one provider for multi-line discounts, reclaim VAT on all mobile costs, claim the full expense against tax, review data allowances to avoid paying for unused data, and consider virtual landlines instead of physical office phones. These steps together can reduce your mobile costs by 30-50%.
How much can a business save by switching to SIM only?
Switching from a handset contract to a SIM only deal typically cuts your per-line monthly cost significantly, because you are no longer paying off a handset. For a team of 10, the annual saving can be substantial. Get a free, tailored quote and we will show you exactly how much you could save.
Can I reclaim VAT on business mobile costs?
Yes. If your business is VAT-registered, you can reclaim 20% VAT on the full cost of business mobile contracts including the handset element. The contract must be in your business name and you must retain VAT invoices. This alone reduces your mobile costs by 20%.
What is the cheapest business mobile deal available?
The cheapest business mobile deals are SIM only plans, with Three usually the lowest cost for small data allowances on a 24-month contract. For a more practical allowance, unlimited data SIM only deals are keenly priced, and VAT-registered businesses can reclaim the VAT on top. Get a free quote for the cheapest deal that fits your usage.
Is it cheaper to use a virtual landline instead of a business phone line?
Yes. A virtual landline is a low-cost monthly service that forwards calls to your mobile, eliminating the need for a more expensive physical office phone line. Virtual landlines are different from VoIP systems they simply give you a local or 01/02 number that diverts to your mobile. This is ideal for small businesses and remote workers.
How does the CTN Switching Promise help reduce costs?
If you are considering switching before a contract ends, check the notice period and early termination fees in your current agreement. Ask the selected provider to set out any switching costs and incentives in writing, then compare the full contract cost before committing.
