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 saves approximately £11+VAT-25 per line per month. A SIM only deal with unlimited data starts from approximately £11+VAT per month ex-VAT compared to approximately £11+VAT-50 per month for a phone contract. For a team of 10, that is a saving of approximately £11+VAT to approximately £11+VAT per year.
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 deal is a SIM only plan from Three at approximately £11+VAT per month ex-VAT for 1 GB data on a 24-month contract. For a more practical allowance, unlimited data SIM only deals start from approximately £11+VAT per month ex-VAT. After VAT recovery, that is just approximately £11+VAT per month for unlimited calls, texts and data.
Is it cheaper to use a virtual landline instead of a business phone line?
Yes. A virtual landline costs from approximately £11+VAT per month and forwards calls to your mobile, eliminating the need for a physical office phone line which typically costs approximately £11+VAT-25 per month. 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?
The Compare The Networks Switching Promise covers agreed early termination fees when you switch to a new business mobile contract through us. This removes the financial barrier of leaving an expensive existing contract. We pay the agreed fees only, not all remaining fees terms apply. This means you can switch to a cheaper deal immediately rather than waiting for your contract to end.
