Why UK Drivers Pay More at the Pump — And What You Can Actually Do About It

There's a particular kind of frustration that hits when you pull into a petrol station, watch the numbers spin past £80, £90, £100, and then see a headline the following morning about how drivers in France or Spain are paying significantly less for the same fuel. It feels unfair. And the uncomfortable truth is: it largely is.

Autocar recently examined the structural reasons behind the UK's persistently elevated pump prices compared with other European nations. But the full picture is considerably more complex — and more politically charged — than any single article can capture. Here's what's really going on, why it matters for your wallet and your rights as a motorist, and what you can practically do about it.

What's Actually Happening at the Pump?

The UK consistently ranks among the most expensive places in Europe to buy petrol or diesel. As of mid-2025, UK unleaded averaged around 136–140p per litre, with diesel hovering similarly. Compare that with Spain, where drivers were paying closer to 130p equivalent, or Luxembourg, long regarded as the fuel bargain of Europe at under 120p.

The gap isn't enormous on a per-litre basis, but it compounds brutally over time. A driver covering 12,000 miles annually in an average family car can easily spend £300–£400 more per year on fuel than their French counterpart — simply because of where they happen to live.

So what's driving that gap?

Why It Matters: The Structural Reasons Behind UK Fuel Costs

1. Fuel Duty — The Elephant in the Forecourt

The single biggest factor is fuel duty. In the UK, fuel duty currently sits at 52.95 pence per litre, a rate that has been frozen since March 2022 following a 5p cut introduced by then-Chancellor Rishi Sunak. Before that freeze, it had been held at 57.95p for over a decade.

On top of that, VAT at 20% is applied to the total price including the duty itself — meaning you're effectively paying tax on a tax. That combined burden accounts for roughly 60–65% of what you pay at the pump, depending on the day's wholesale oil price.

Other European countries also levy fuel taxes, but many apply lower rates or use different VAT structures. France applies a VAT rate of 20% but with lower base duty. Spain's duty is lower still. The UK's combination of high duty and full-rate VAT creates a particularly heavy burden.

2. Wholesale Pricing and Currency Exposure

Crude oil is priced globally in US dollars. When the pound weakens against the dollar — as it has done repeatedly since Brexit — the cost of importing oil rises in sterling terms, even if the dollar price of crude hasn't moved. This currency exposure is a structural disadvantage the UK has faced more acutely than many eurozone neighbours, whose single currency provides a degree of collective stability.

3. Supply Chain and Refinery Capacity

The UK has seen significant reductions in domestic refinery capacity over the past two decades. Several major refineries have closed or been repurposed. This means the UK is more reliant on imported refined products than some European counterparts, adding logistics costs and market exposure that feed directly into pump prices.

4. Retailer Margins — The Quiet Profiteer

The Competition and Markets Authority (CMA) launched a formal investigation into fuel retail pricing in 2023 and found evidence that supermarket and forecourt margins had widened significantly — particularly as wholesale prices fell but pump prices remained stubbornly high. The CMA's 2023 fuel report concluded that the sector was not functioning competitively enough, and that drivers were being overcharged by an estimated 6p per litre compared with what a competitive market would produce.

A statutory scheme — the Pumpwatch fuel price monitoring system — was subsequently proposed to improve price transparency, though its implementation has been slow and contested by industry.

The Legal Angle: What Rights Do UK Drivers Actually Have?

This is where things get interesting — and where many drivers don't realise there are genuine legal frameworks in place.

The Pumpwatch Transparency Scheme

Under proposals stemming from the Energy (Oil and Gas) Profits Levy Act 2022 and subsequent CMA recommendations, the government has powers to compel fuel retailers to publish real-time pricing data. The goal is to allow price comparison apps and services to function effectively, driving competitive pressure. At time of writing, the government has legislated for this through the Fuel (Transparency and Competition) provisions embedded in broader energy legislation, though enforcement remains patchy.

Consumer Protection from Unfair Trading Regulations 2008

While these regulations are more commonly applied to misleading advertising, they technically cover situations where traders engage in commercial practices that distort consumer decision-making. If a retailer is advertising prices at the roadside that don't match the actual pump price, this could constitute a breach. Always check the price before you start pumping.

The Competition Act 1998

The CMA has powers under this Act to investigate and sanction anti-competitive behaviour in fuel markets. The 2023 investigation used these powers, and the resulting Pumpwatch scheme is a direct product of that legal process. Drivers can submit complaints to the CMA if they believe local pricing is artificially inflated or coordinated between nearby retailers.

What Drivers Should Know: Practical Advice for Right Now

You can't change fiscal policy from your driveway, but you can make smarter decisions that meaningfully reduce what you spend.

Use real-time price comparison tools Apps such as Confused.com's fuel finder, PetrolPrices.com, and Waze (which integrates fuel pricing in many areas) allow you to identify the cheapest forecourt within a reasonable detour. Even a 3–4p per litre saving on a 50-litre fill-up is worth £1.50–£2.00, and those savings accumulate.

Supermarket fuel: still the best deal Despite the CMA's concerns about widening margins, supermarket forecourts — particularly Asda, Tesco, Morrisons, and Sainsbury's — consistently undercut motorway services and branded stations by 5–10p per litre. If you have a supermarket nearby, use it.

Avoid motorway services wherever possible Motorway service station fuel is almost always the most expensive in the country, sometimes by 15–20p per litre. Plan your journeys to fill up before you join a motorway or at a junction where alternatives exist.

Loyalty schemes and cashback Several supermarkets offer fuel vouchers linked to grocery spend. Tesco Clubcard and Morrisons More both periodically offer fuel discounts. Cashback credit cards (used responsibly and cleared monthly) can also effectively reduce your per-litre cost by 1–2%.

Drive efficiently This sounds obvious, but the difference between aggressive and smooth driving on a typical journey can be 10–15% in fuel consumption. Maintaining steady speeds, anticipating braking distances, and keeping tyres properly inflated (check the placard inside your door jamb for the correct pressure) all make a measurable difference.

Consider timing your fill-ups Fuel prices tend to be adjusted by retailers on certain days of the week. Historically, prices are often raised on Thursdays ahead of weekend demand. Filling up mid-week — particularly on Tuesdays or Wednesdays — has anecdotally been cheaper, though this varies by region and retailer.

Looking Ahead: Will UK Fuel Prices Ever Come Down?

The honest answer is: not dramatically, and not soon.

Fuel duty represents approximately £24–26 billion annually to the Treasury. Any government — regardless of political stripe — faces enormous fiscal pressure when considering cuts. The 5p reduction introduced in 2022 cost around £2.4 billion per year and was politically popular but fiscally painful. The freeze has been extended repeatedly, but there is no credible political pathway to a substantial duty cut in the current environment.

The longer-term trajectory is shaped by electrification. As the UK's EV fleet grows, fuel duty receipts will fall — which creates pressure to either raise duty on remaining petrol and diesel users or introduce replacement revenue mechanisms such as pay-per-mile road charging. Either outcome is likely to keep motoring costs elevated for the foreseeable future.

The Pumpwatch transparency scheme, if implemented effectively, could narrow the retailer margin gap and save drivers several pence per litre. The CMA has indicated it will monitor compliance closely, and there is genuine regulatory appetite to act if retailers continue to pocket excessive margins as wholesale prices fluctuate.

What's clear is that the structural disadvantages facing UK drivers — high duty, currency exposure, reduced refinery capacity, and imperfect retail competition — are not going to resolve themselves. The best defence available to most motorists right now is information: knowing where to buy, when to buy, and how to drive more efficiently.

In a market where the deck is structurally stacked against you, every informed decision at the forecourt is a small act of financial self-defence.
