- Count the lines. Compare the number of lines or SIMs on the bill with the number your team uses.
- Look for add-ons. Insurance, security, static IPs and paper-bill charges add up.
- Check out-of-bundle charges. Roaming, premium numbers and data over the allowance.
- Check equipment. Handset payments that should have ended, or router rental on kit you own.
- Check the dates. Find out whether you're in or out of contract (Ofcom: in or out of contract).
Ofcom also lists charges to look out for: leaving early, paper billing, roaming and not giving enough notice (Ofcom). Use the bill checker to make your list.
