Last year the mobile phone networks overcharged UK businesses and consumers approximately £7,600,000,000.

We're here to keep them honest.

Keeping the networks honest
How much could you save?

How many devices do you have?

Let us know how many devices (phones and tablets) you have and we’ll give you a rough estimate of how much you’re being overcharged.

Now get it spot on.

If you give us your phone account details for online billing, our evidence-based engine can 'crunch' your bill and discover the best plan for your business (49% savings average).

We’ll then arrange a free, no obligation consultation to talk you through the findings.

Don’t worry if you don’t have your account details to hand, just send us your contact details via the form below and we’ll email you about how to find out how much you could save.

How it works

Let Billmonitor find out exactly how much you're being overcharged and match you to the right contract

And if you’re mid-contract, our monthly Bill Check-up helps you make the most of it.

  1. Billmonitor analyses your mobile bills

  2. Analyses your usage against 2 million contracts

  3. Billmonitor matches you to exactly the right new contract

  4. Each month, Bill Check-up helps you save on your current contract and it alerts you when you're free to switch to a new contract

Case Studies

Billmonitor helps CSH Surrey, Surrey's largest NHS community services provider.


I was initially sceptical about Billmonitor’s ability to achieve savings as our average cost per connection was already less than £10 on public sector tariffs but they really exceeded our expectations and reduced our contract costs by nearly 50%.

Research

The Billmonitor investigation into the B2B mobile provider ‘Wild West’ reveals that only one in ten SMEs get a fair deal from their providers, while Ofcom turns a blind eye.

Billmonitor’s consumer service was the first mobile tariff comparison service to be officially accredited by Ofcom, the UK telecommunications regulator, and forms part of the UK government’s MiData project.

If you do nothing else, ask these three questions to your network provider

1
‘How many dormant devices do we have?’
Hint:

Most businesses have dormant devices they’re not aware of (and that the networks won’t tell you about unless you ask). This alone means the average business is being overcharged by more than 10%.

2
‘How much does it cost us when we go over our monthly allowances for data or international calls?’
Hint:

Many businesses incur massive charges when they go over their monthly allowances, especially for data and international calls. Having the right bundles can prevent this and dramatically reduce costs.

3
‘What percentage of our bill is allocated to handsets?’
Hint:

There is no such thing as a free handset – the higher your monthly tariff, the larger the handset fund you should be offered. On average a good handset fund represents about 40% to 50% of your total contract costs.

Three Mathematicians

Billmonitor was launched in 2009 by three mathematicians in Oxford.

Using advanced maths to turn the complexity of bills and tariffs into simple, actionable intelligence, it allows users to make informed decisions and save money in a market where the networks do their best to keep things murky.
