TCR Banding

TCR Banding: A Powerful but Overlooked Way to Lower Energy Costs for UK Businesses


As UK business energy prices continue to fluctuate at historically high levels, companies across the country are under increasing pressure to find reliable ways to
lower energy costs. With government levies, non-commodity charges, and market instability all contributing to rising bills, businesses must now look beyond traditional energy-saving methods to manage their expenses. In previous articles we looked at how to lower kVA charges, and published a guide on how to lower business energy costs.


One such method gaining attention is 
TCR Banding - a relatively lesser-known, yet impactful solution for reducing DUoS and TNUoS charges.


What Is TCR Banding?

TCR Banding is part of the Targeted Charging Review (TCR), a reform introduced by Ofgem in 2022. Its goal is to ensure a fairer, more consistent system for charging UK electricity users for their share of the grid's maintenance costs -- specifically the Transmission Use of System (TUoS) and Distribution Use of System (DUoS) charges.

Instead of charges being based on when energy is used (which could be manipulated by large users), charges are now fixed and based on how much energy is typically consumed or the agreed capacity. This is where TCR Bands come into play. This leads many businesses ask what is their TCR banding? As, without having previously discussed this with your DNO, you could be in the dark regarding exactly which TCR band your sites are in.


What Are TCR Bands?

TCR Bands categorise electricity meters into different levels based on their voltage type and agreed kVA capacity. These bands determine the fixed DUoS and TUoS charges applied to a business's energy bill.


For Low Voltage (LV) Half-Hourly Meters:

  • Band 1: 0 – 80 kVA
  • Band 2: 81 – 150 kVA
  • Band 3: 151 – 231 kVA
  • Band 4: 232 kVA and above


For High Voltage (HV) Half-Hourly Meters:

  • Band 1: 0 – 422 kVA
  • Band 2: 423 – 1,000 kVA
  • Band 3: 1,001 – 1,800 kVA
  • Band 4: 1,801 kVA and above


The higher your TCR band, the more you'll pay in fixed DUoS and TUoS charges, making it essential for UK businesses to ensure their banding is correctly assigned.


Who Assigns Your TCR Band?

Your Distribution Network Operator (DNO) is responsible for assigning your TCR Band. DNOs are regional companies that manage the physical infrastructure delivering electricity to your site. They’re the ones compensated through DUoS and TUoS charges shown on your business energy invoice.


The initial banding is typically based on your historic energy consumption and agreed capacity, but each DNO may have slightly different processes for determining and reviewing your band.

How to Check Your TCR Band

Unfortunately, your TCR Band is not usually listed on your energy bill, making it hard to verify whether you’re in the correct category. To confirm your banding, you often need to contact your DNO directly --  or work with a business energy consultant who can check it on your behalf.


Why Your TCR Band Could Be Wrong - and Costing You Money

Many UK businesses may be overpaying on DUoS and TUoS charges due to incorrect or outdated TCR Band assignments. If your energy consumption has decreased in recent years --due to efficiency upgrades, changes in operations, or energy-saving initiatives -- your band may no longer reflect your actual usage. Without a manual review, you might be stuck in a higher band, paying more than necessary in fixed network charges.


Lower Your Energy Costs Through TCR Band Reviews

If you're looking for a strategic, often overlooked way to lower your UK business energy costs, reviewing your TCR Banding could be a game changer. Ensuring accurate band classification not only reduces unnecessary charges but also maximizes the impact of your energy-saving efforts.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
