EII Network Charge Compensation & Supporting Levy (from April 2025)

From April 2025, eligible Energy Intensive Industries (EIIs) will receive compensation on network charges such as TNUoS, DUoS and BSUoS.

What this means for you:
Contact us if you need support or you are not sure if you qualify as an EII, we will make sure your eligibility and certificates are up to date. This will reduce your network charge burden significantly.

If you are not EII-eligible, you may bear additional costs via supplier pass-throughs. Factor that into your budget.

What This Means for You?

Budgeting becomes more complex. Even fixed energy rates may be paired with fluctuating pass-throughs, especially after 2025.

Contract renewal strategy matters. When we renegotiate with you, we’ll model multiple scenarios so you are protected from surprises.

Load management pays off more. Shifting energy usage away from expensive times and locations can reduce exposure to network and levy charges.

Certification is critical for EIIs. If your business is or could be eligible, managing your certificates can translate into real savings.

What You Should Do Now

What Is

Non-Energy?

Non-energy (pass-through) costs are the additional charges that support the infrastructure, regulation, and schemes that keep the energy system running.

Our Advice:

Check your EII eligibility now and start the application process early.
If you are already certified, make sure you renew on time.
Contact our team. We can guide you through the process, explain what data you’ll need, and help you avoid missing out on relief.

Non-Energy Charges

How can I reduce non-energy costs?

1. Use your business' data
If you can't measure it, you can't manage it
Reducing your costs starts with controlling your consumption, and for that you need insights into your usage. Advantage Analytics is a world-class data analytics platform that gives you insights into every aspect of your energy usage.

Check out our Advnatage Analytics platform that allows you to access site data and usage from anywhere in the world.

2. Spread your usage
Time of day affects your costs
By avoiding using energy at certain times of the day, you could potentially make savings on time-sensitive non-energy charges. This includes ‘Transmission Network Use of System’ (TUoS) and ‘Distribution Use of System’ (DUoS) costs.

3.Reduce your usage
Small changes can make a big difference
Making changes to your energy usage through increasing your efficiency—including improving your insulation, upgrading your lighting and investing in new equipment—not only reduces your wholesale costs, but can lower your non-energy costs. Your Climate Change Levy (CCL) contribution depends on the volume of energy your business uses, so lowering your usage could reduce your costs beyond just what you’re saving on your consumption.
