I filled up last week and nearly choked at the pump - genuinely worse than I expected. What people don't always realise is that UK fuel duty is fixed, so when wholesale costs spike, there's basically nothing the government can do to soften the blow in the short term. We're stuck paying whatever the market decides, and that fixed duty just sits on top making the total look even worse.
The other thing worth mentioning is that summer demand genuinely peaks around August into early September, so refineries are actually working through whatever stock they built up during lower-demand months. By the time people start thinking about bank holiday trips, prices have already been climbing for weeks - it's not that petrol companies are deliberately squeezing holiday travelers, it's more that demand from all sectors (heating, transport, industry) converges at once. You'll see prices come back down once summer driving season properly winds down, but yeah, the timing absolutely sucks if you're planning a road trip right now.
