TCR: All your business needs to know

Targeted Charging Review (TCR): three words that have frustrated business owners and professionals responsible for business energy for almost three years.

Finally, some clarity is emerging around how the changes will be implemented and where businesses can monitor the effect on their bills.

What is TCR?

Two of the non-commodity costs on business’ electricity bills, itemised as TNUoS (Transmission Network Use of System) and DUoS (Distribution Network Use of System), are being removed and re-distributed in other charges.

Ofgem (Office For Gas and Electricity Markets) has introduced this due to uneven distribution of these charges between large and small business consumers.  This is partially due to load-shedding strategies employed by larger consumers, which means they are not contributing equally to maintenance of the country’s electricity network.

What are the changes?

TNUoS changes have been delayed for a second time and will come into effect in April 2023, whilst DUoS changes will take place in April 2022.

The new TNUoS charges will be banded based on a business’ agreed supply capacity (ASC), also known as its kVA, and applied through other areas of the bill.  At Great Annual Savings Group (GAS), we’re increasingly finding that these are being applied through the standing charge in the short term by most suppliers.

Both TNUoS and DUoS replacement charges will be dependent on region and will be calculated using the 24-month period ending in 2020.  This applies to businesses on non-half-hourly supplies as well as larger half-hourly consumers.

Criticisms of the changes

The largest criticism of TCR is from those who have employed renewables on-site.  The incentive to harvest renewable power and utilise it during annual periods of peak consumption (Triads) has been removed.  This has been a valid load shedding tactic for some time and has helped larger consumers manage their energy costs, but is now seen by Ofgem as businesses avoiding paying their share.

TCR has been criticised by the clean energy sector for creating a barrier to adoption and punishing those businesses who have been pro-active in generating clean energy.

Liam Stoker, Editor-in-chief at Current+, wrote: “Various studies have countered Ofgem’s analysis, drawn up by Frontier Economics, claiming that the policy stands to wipe £2.50 off the value of each megawatt hour generated by renewables, damaging project economics and wiping multiple gigawatts off of post-subsidy pipelines.”

Such fervent criticism has resulted in the launch of another review, the Strategic Charging Review, which is worth keeping an eye on.

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.
