While the headlines might be dominated by the electric revolution, the reality on Britain’s forecourts is often different. For millions of motorists buying used or brand-new vehicles this year, the biggest decision remains the classic heavyweight fight: petrol vs. diesel. It used to be a simple equation: you bought petrol for performance and short trips, and diesel for economy on long hauls. Today, thanks to advanced engine technology, fluctuating fuel prices, and the spread of Clean Air Zones (CAZ), the choice is far more nuanced. If you are stuck at the pump crossroads, here is a practical breakdown of how the two fuels stack up in the current landscape.
For the last decade, we’ve been told that diesel’s days are numbered. With the rise of EVs and the expansion of Clean Air Zones across the UK, many motorists assumed the "black pump" was heading for the history books. However, as we move through 2026, a surprising trend has emerged: the diesel engine is far from dead. For a specific group of UK drivers, a modern diesel remains the most practical, economical, and durable choice on the market. Here is why owning a diesel vehicle in 2026 still offers benefits that petrol and electric cars struggle to match.
If you owned or leased a diesel vehicle in the UK between 2008 and 2020 , you might be sitting on a significant compensation claim. What started with the Volkswagen "Dieselgate" scandal has evolved into one of the largest legal actions in British history. As we move into 2026, the legal landscape has reached a boiling point. Here is everything you need to know about the current state of diesel emissions claims and why the window to act is narrowing.
