First, do not cancel any direct debits and ensure you have let the retailer know if you are struggling to make payment. Failure to pay can lead to interest build-up and affect your credit.

Next – submit a new meter read. This will recalculate your usage on your next billing period and generate an accurate bill. From here you can clear down the balance or set up a payment plan.

The most common cause of bills being inaccurate is estimated reads: submitting regular reads is vital.

If you believe you have a leak: contact your retailer and request their support.

  • Take regular meter readings and cross check with your water bill
  • Establish consumption when facility is closed or at low occupancy this will help identify any potential leaks or unnecessary use
  • Carry out regular checks on overflows, pipework, valves and water using appliances
  • Undertake water efficiency audit

Paul JohnsonGroup Financial Director

Paul Johnson is very much a home-grown talent.

He joined Great Annual Savings Group in its infancy, fresh from a youth career as a professional footballer with Hartlepool United.  He quickly established a reputation within the business and aced all required accountancy qualifications in the space of four years to become the Group’s Management Accountant.

Several successful projects later, Paul was promoted to Head of Finance.  When the former FD left GAS, he took on the mantle of the business’ most senior finance professional; boasting a string of incredible achievements all under the age of 30.


“I have witnessed phenomenal growth at the Group over the many years I’ve worked here and I’m looking forward to guiding the Group into an exciting new chapter.”

Interesting fact:

Paul made his professional debut for Hartlepool United against Bournemouth in the Football League.  Some say Danny Ings still resides in his pocket to this day.

We want companies to be pro-active and take the pain away by saving costs now, letting GAS do the fully managed cost solution just makes good business sense for any company, whatever the size or industry. Our business ethos is something I truly believe in and want every company to benefit from our help and support, working collaboratively together is a great way to build long term relationships.”

Bradley GrovesChief Executive & Founder

Having founded GAS in 2012, Brad has overseen the company’s huge growth in a short space of time. Starting from modest surroundings in South Shields, rapid progress has seen the business move to its current office in Seaham, which is being expanded across the business park to create an 80,000 square foot GAS campus, featuring one of the finest headquarters buildings outside of London and Manchester.

The majority of Brad’s career has been spent on the boards of FTSE companies, at board level in the private sector and in turnaround private equity.  He was Group MD of Caudwell Group and worked on its sale in 2006 for £1.5 billion.

Brad says:

"Certain businesses we’ve worked with have made six-figure savings over their contract terms. We cover the widest range of business variable costs in the market in one place.  When we get involved with a company, it allows them to focus on their core business.  The extra time we allow them to spend on their strategies can often prove as valuable as the cash we save them."
