Rachel Reeves’ Proposed Energy Bill Cuts: What You Need To Know

Published: 24 September 2025 | By Energy Solicitors Limited

With energy prices still a concern and economic uncertainty continuing across the UK, Chancellor Rachel Reeves is expected to announce a range of measures aiming to reduce household energy costs. Such proposals are expected to be announced in the Autumn Budget on 26th November 2025, however, they could have a broader impact on both consumers and the energy industry.

Key Proposals Under Review

VAT Reduction on Energy Bills

Reeves is exploring the possibility of reducing the current 5% VAT rate on domestic energy to zero. This could save the average household around £86 per year but would cost the Treasury an estimated £1.75 billion annually. While the proposal offers immediate relief, experts caution that it may disproportionately benefit higher-income households with greater energy usage.

Green Levy Reform

Green levies, which fund renewable energy and environmental initiatives, currently add approximately £215 to the average household bill. Their removal or reform is currently being considered to reduce pressure on consumers, though this could impact the UK’s climate commitments and energy supplier funding models.

Legal and Policy Implications

While the VAT cut could help ease energy costs in the short term, it’s essential to consider its long-term impact on public finances. 

Impact on Energy Suppliers and Existing Contracts

Changes to VAT and levies could affect existing energy supply contracts, particularly those with fixed pricing structures or clauses tied to government-imposed charges. Businesses, landlords and developers should review their agreements to assess potential exposure or opportunities for renegotiation.

Regulatory Compliance and Subsidy Reform

If green levies are removed or incorporated into general taxation, energy suppliers could face new compliance and reporting requirements. Legal guidance will be essential for businesses adapting to these transitions and aligning with the UK’s net zero commitments.

Political and Economic Uncertainty

With a £40 billion shortfall in public finances, there’s growing speculation that any savings from energy bill reforms could be offset by tax increases elsewhere. In this uncertain landscape, businesses should prepare for regulatory shifts to manage potential risks.
