Call us: 0800 689 3035

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.

We’ll need your mobile account login details to be able to analyse your bills.

Case Study

CSH Surrey, Surrey's largest NHS community services provider, cuts contract costs by nearly 50%.

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%.

See case study

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.

Read the report

Case Study

Barts Cancer Institute, the leading public sector research centre, saves 42%.

It was important for us to find a truly independent advisor who would also be able to support the BCI throughout the switching process and Billmonitor truly exceeded our expectations.

See case study

Case Study

Billmonitor helps a London-based investment management firm save £92,000.

By identifying historical billing errors and selecting tariffs and bundles matching the client's usage, Billmonitor saved the firm £92,000 and will now periodically review for further optimisations as part of our monitoring service.

Billmonitor’s consumer service was the first mobile tariff comparison service to be 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

‘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%.

‘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.

‘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.
