The Real Cost of Poor Business Telecoms in the UK

UK small and medium businesses lose thousands every year to fragmented phone systems, missed calls and overpriced telecom contracts. Here are the numbers your current provider doesn't want you to see.

Multiple Telecom Providers

Multiple contracts, multiple invoices, no single view of what your business actually spends on telecoms. UK SMEs overspend an average of £8,700 annually on fragmented telecom services.

Ofcom SME Telecoms Report

Missed Business Calls

Calls ring out, customers hang up and move on to a competitor. No voicemail fallback, no automatic callback, no sale. Every missed call is lost revenue.

BT Business Research

Staff Using Personal Mobiles

No company caller ID, no call recording, no oversight. When employees leave, your client relationships and contact history walk out with them.

ISPA Business Survey

Telecom Costs That Scale Badly

Every new hire means another provider contract, another handset, another setup fee. Traditional business phone systems cost up to 40% more than unified cloud solutions.

These problems cost UK businesses billions every year. See how TISA solves all four →
