FairFuelUK says official UK Government data indicates diesel and petrol drivers have been consistently overcharged over the past 12 months.
Using DESNZ monthly retail fuel prices and ONS refined‑petroleum wholesale indices converted into pence per litre, FairFuelUK found that the retail–wholesale margins for both fuels have widened dramatically — in many months exceeding 100 pence per litre.
The findings reveal a clear pattern: wholesale fuel prices have risen only modestly, yet pump prices have surged and remained high, creating margins that cannot be justified by supply‑chain costs, taxation, or market conditions.
Key Findings in the last 12 months
Diesel
- Wholesale diesel barely changed: +1.2% (76.7ppl → 77.6ppl)
- Retail diesel jumped sharply: +18.9% (153ppl → 182ppl)
- Diesel margins exploded: +36.8% (76.3ppl → 104.4ppl).
Petrol
- Wholesale petrol barely changed: +1.4% (62.3ppl → 63.2ppl)
- Retail petrol rose strongly: +12.2% (148ppl → 166ppl)
- Petrol margins jumped: +20.0% (85.7ppl → 102.8ppl)
Across both fuels, margins have grown far faster than wholesale costs — leaving motorists, hauliers, tradespeople, and small businesses paying significantly more than justified.
Howard Cox, Founder of FairFuelUK, said, “This data proves what drivers have known for years: pump prices shoot up like a rocket when wholesale rises, but drift down like a feather when wholesale falls.
“Wholesale diesel and petrol have barely moved — yet retail prices have soared and stayed high. Motorists are being fleeced, and it’s time for full transparency and proper oversight.”
He added, “Since the Iran crisis began, more than 40 countries have stepped in to protect their drivers from global fuel volatility — cutting taxes, capping margins, enforcing transparency, or directly intervening to stabilise pump prices.
“Yet here in the UK, motorists have been left completely exposed. The Government has done nothing meaningful to reduce pump prices, nothing to rein in inflated margins, and nothing to protect drivers from the rocket‑and‑feather rip‑off that has become standard practice on our forecourts.”
Why have margins exploded? FairFuelUK’s analysis identifies several structural causes:
- Rocket‑and‑feather pricing: Retail rises instantly when wholesale rises, but falls slowly when wholesale drops.
- Risk premiums added but never removed: Retailers price in volatility even when volatility disappears.
- VAT amplifies every retail increase: VAT is charged on the entire pump price, not just the fuel.
- Weak competition: Supermarkets no longer aggressively undercut; independents follow supermarket pricing.
- Wholesale opacity: Consumers cannot see wholesale prices, enabling margin inflation.
- Retail margin inflation: Retail margins have quietly grown from ~15–20ppl to ~25–30ppl.
FairFuelUK urges the Government and regulators to implement:
- Mandatory wholesale–retail transparency
- Real‑time margin reporting
- Independent oversight of pump pricing behaviour
- A freeze in Fuel Duty for the lifetime of this Parliament
- A Competition & Markets Authority investigation into retail fuel margins
“Drivers deserve fair, transparent fuel pricing — not inflated margins,” Cox added.
