Lib Dems Unveil £2bn Plan to Cut Fuel Duty by 10p a Litre 2026

The Liberal Democrats have unveiled a £2bn plan to cut fuel duty by 10p a litre for a fixed three-month period, as part of a broader effort to define their policy identity ahead of the next general election. The proposal, announced at the party’s autumn conference in Brighton, aims to ease the financial burden on motorists and stimulate economic activity.

What the Lib Dems Are Proposing

Under the plan, fuel duty would be reduced by 10p per litre for three months, costing the Treasury an estimated £2bn. The party also proposes cutting the £3 cap on bus fares to £1 and reducing rail fares by 10%. These measures are designed to tackle the cost-of-living crisis and encourage the use of public transport.

Party leader Ed Davey is expected to outline the full details in his keynote speech on Tuesday. Deputy leader Daisy Cooper has already highlighted plans to boost economic growth through closer ties with Europe, including a long-term ambition to rejoin the EU single market.

Why the Lib Dems Are Pushing This Plan

The announcement comes amid concerns that voters are unfamiliar with the party’s policies. Polling suggests Lib Dem policies are less well known than those of Restore Britain, a newly launched party with just one MP. The Lib Dems, who currently have 71 MPs, are static in national polling at around 12%.

Davey has pushed back against the idea that the party risks being forgotten amid the rise of Reform UK and the Greens. “I’m talking about real change, not just talking about the bubbles,” he told the BBC. The fuel duty cut is positioned as a tangible measure that would directly benefit households and businesses.

How the Fuel Duty Cut Compares

To understand the impact, consider how the proposed cut stacks up against current fuel prices and other party proposals.

Key Takeaways for Consumers

• Short-term savings: A 10p cut in fuel duty could save the average driver around £5 per fill-up, based on a 50-litre tank.
• Economic stimulus: The measure aims to boost consumer spending by reducing transport costs.
• Political positioning: The Lib Dems hope to differentiate themselves from other parties with concrete, costed proposals.
• Limited duration: The cut would only last three months, after which fuel duty would revert to current levels unless extended.

Potential Impact on the Economy

While the fuel duty cut would provide immediate relief to motorists, economists are divided on its long-term benefits. Some argue that temporary tax cuts can stimulate demand and help lower-income households. Others caution that they add to government borrowing without addressing structural issues in the transport sector.

The Lib Dems argue that their broader plan, including closer ties with Europe, would foster sustainable growth. However, with the party polling at around 12%, the challenge remains convincing voters that these policies are credible and achievable.
