Many CCA-holding businesses are paying full CCL rates in error and are owed years of refunds. Our invoice audits identify and recover overpayments back up to 4 years — at no upfront cost.

You have a CCA.
Are you getting the full discount?

If your business holds a Climate Change Agreement, you're entitled to discounts of up to 92% on electricity CCL and 89% on gas. Billing errors are common — and the financial impact can run to tens of thousands of pounds. EnergyFit audits your invoices and recovers what you're owed.

CCL and CCAs: the tax discount most businesses don't fully claim

The Climate Change Levy is a government tax on business energy. Climate Change Agreements entitle qualifying businesses to major discounts — but only if your supplier bills the correct reduced rate.

What is the Climate Change Levy?

The CCL is an environmental tax charged on electricity and gas supplied to non-domestic users in the UK. It appears as a separate line on your energy invoice, collected by your supplier on behalf of HMRC.

Standard 2025/26 rates: £0.00775/kWh for electricity and £0.00452/kWh for gas — charges that compound significantly at industrial and commercial scale.

What is a Climate Change Agreement?

A CCA is a voluntary agreement between an energy-intensive business and the Environment Agency. In exchange for meeting energy efficiency or carbon reduction targets — reported over two-year terms — your business receives substantial CCL discounts.

If your sector qualifies and you're not claiming the full discount, you may be significantly overpaying your energy tax.

Who qualifies for a CCA?

  • Energy-intensive manufacturing sectors
  • Food and drink production
  • Paper and printing industries
  • Ceramics, glass and cement manufacturing
  • Data centres and large commercial facilities
  • Agricultural businesses (certain operations)
  • Other designated energy-intensive sectors

Why are businesses overpaying?

  • Supplier fails to apply CCA reduced rate to invoices
  • PP11 exemption certificate not renewed or filed correctly
  • Site or meter changes not communicated to supplier
  • Entitlement on additional sites not identified
  • Incorrect rates applied at tariff change dates

Illustrative estimates based on 2025/26 standard vs CCA reduced electricity CCL rates. Actual recovery depends on energy volumes, tariff history, and overpayment period.

Our Service

From invoice audit to HMRC claim — we handle everything

Most businesses don't have the internal resource or regulatory expertise to identify and recover CCL overpayments. We do this on your behalf, from first audit to final payment.

1

CCA status verification

We confirm your current CCA registration, the applicable sector agreement, correct discount rates, and whether your PP11 supplier certificates are correctly filed and up to date across all sites.

2

Invoice audit across all meters and sites

We review up to four years of electricity and gas invoices — comparing CCL rates actually charged against rates you're legally entitled to under your CCA, meter by meter.

3

Overpayment quantification

We produce a detailed schedule of overpaid CCL per meter and period, with a total recovery figure and supporting calculations ready for HMRC submission.

4

HMRC application and supplier liaison

We prepare and submit your CCL reclaim to HMRC and manage all supplier communications — ensuring correct reduced rates are applied going forward and historic overpayments are returned.

5

Ongoing compliance monitoring

We implement ongoing monitoring to ensure CCL is billed correctly at every rate change date, and that your CCA exemption certificates are renewed before they lapse — protecting future savings permanently.
