About Pump Trumps

Public overview of what the application does and how it uses official UK fuel data.

Overview

Pump Trumps is a webapp built around UK gov.uk Fuel Finder data: it syncs official petrol-station and fuel-price feeds, then exposes them through an admin-style viewer and consumer-facing tools so you can explore stations and prices, search by postcode or place for nearby forecourts, drill into regions and brands, monitor price changes, plan routes with fuel in mind, and review data quality—with extra views such as retail-outlet aggregates, fair pump price, and city price spreads. Behind the scenes it runs scheduled or on-demand sync jobs against the Fuel Finder API, and it can be deployed with authentication, user registration, and operational pages (status, logs, admin actions) for running refreshes and checks in production.

Interesting Facts

  1. Petrol vs diesel popularity has shifted

    Diesel used to dominate UK car sales (especially in the 2000s), but after emissions concerns and policy changes, petrol cars are now more common again.

  2. The UK uses RON ratings for petrol

    Fuel is labelled by octane rating (RON):

    • Regular petrol: 95 RON
    • Premium petrol: 97–99 RON

    Higher RON helps performance engines run more efficiently.

  3. E10 petrol became standard in 2021

    The UK switched to E10 petrol (up to 10% ethanol) to reduce emissions. This cut CO₂ emissions by the equivalent of removing hundreds of thousands of cars from the road annually.

  4. Not all cars are E10-compatible

    Most modern cars are fine, but some older vehicles (especially pre-2011) may need E5 petrol, which is still available as “premium.”

  5. Fuel duty makes up a huge portion of price

    A large chunk of what you pay at the pump is tax: around 50–60% of fuel price is fuel duty plus VAT—so you are often paying more in tax than in underlying fuel cost.

  6. The UK has one of Europe’s highest fuel prices

    Due to taxes, the UK consistently ranks among the most expensive places in Europe for petrol and diesel.

  7. Supermarkets are major fuel sellers

    Chains like Tesco and Asda sell massive volumes of fuel and often undercut traditional petrol stations, influencing national pricing trends.

  8. Red diesel exists (but not for cars)

    “Red diesel” is cheaper fuel used for agriculture and construction equipment. It is dyed red to prevent illegal use in road vehicles—using it illegally can lead to heavy fines.

  9. The UK is phasing out petrol and diesel cars

    The UK government plans to ban sales of new petrol and diesel cars by 2035 (with hybrids allowed until then under certain rules).

  10. EV charging is rapidly expanding

    As fuel use declines, the UK is investing heavily in public charging networks and fast chargers on motorways. Electric vehicles are becoming a major alternative to traditional fuels.
