Voltage Optimisation

Don’t be put off by the fancy name, voltage optimisation is a simple concept.

The Electrical Safety, Quality and Continuity Regulations 2002 state that electricity supplied to a building should be 230V with a 10% margin for error.  This means the electricity supplied to your building could be anything between 216V and 253V.

Voltage optimization unit regulates this voltage according to what your equipment needs.  It cuts out the waste with no changes to behavior or operation, often resulting in marked improvements to performance.

Another form of this method is ‘Power Factor Correction’, which works in a similar way but uses a different piece of technology.  This controls the actual supply of energy to your building, which varies according to the infrastructure in your area.

The cost and suitability of a Voltage Optimisation unit must be carefully considered as each business’ needs are different.  A unit to manage a standard house can be bought for around £500, but each business’ premises are different in size and set up.

We’d always recommend consultation with an expert before installation, but their instant impact on usage usually leads to a substantial cost saving in a very short amount of time and quick repayment of the outlay required to install them.

There’s one you may not have considered before.

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.
