- Does this page include areas around Cardiff?
- Yes. The map shows fuel stations in Cardiff and nearby areas based on what you're viewing on the map. If you're just outside Cardiff, zoom out slightly or search your postcode.
- How do I find the cheapest fuel and diesel in Cardiff?
- Use the fuel filter (fuel, super unleaded, diesel) and sort by price. You can also tap "Locate Me" to jump to your current area in Cardiff.
- What affects fuel and diesel prices in Cardiff?
- Fuel and diesel prices in Cardiff change because the cost of oil changes, the pound's exchange rate changes, and fuel has to be refined and delivered. On top of that, the government adds fuel duty and VAT, and each station sets its own profit margin. In Cardiff, local competition and proximity to distribution centers also play a role. That's why at Resolvo we've built a live price map tool to help you track these fluctuations and find the cheapest fuel and diesel nearby in real-time.
- How much of the pump price is tax?
- A big part of what you pay is tax. The UK adds fuel duty and then VAT on top of the total. For example, on £20 of fuel (at an average price of 135p/litre), you are paying roughly £11.17 in tax (£7.84 in duty and £3.33 in VAT). That means over half of your payment goes straight to the Treasury.
- Why is diesel sometimes more expensive than fuel?
- Diesel can cost more because it can be harder to make in large enough amounts, and demand can be high (for vans, delivery fleets, and some cars). Sometimes fuel is higher instead — it depends on global supply and demand and what refineries are producing at the time.
- Why is fuel and diesel more expensive at motorway services near Cardiff?
- Motorway service stations usually charge more because they have higher running costs and less competition right next door. People also pay for convenience because they're already on a long trip. If you're traveling through Cardiff, fill up in town before joining the motorway to save money.
- Why is the price on the Resolvo map different from the price at the pump in Cardiff?
- Prices can be different because stations in Cardiff change prices during the day and it can take time for updates to show. Also, some stations run short promotions or loyalty discounts that aren't included in standard price feeds. Treat online prices as a strong guide, and always trust the sign at the station.
- How often do fuel stations in Cardiff change prices?
- There's no fixed time. Some stations in Cardiff change prices daily, some change a few times a week, and some change whenever nearby stations change. That's why it's worth checking Resolvo's live map close to the time you plan to fill up.
- Why did pay-at-pump take or 'hold' £99/£100 on my card?
- That's a temporary pre-authorisation hold. The pump asks your bank to approve up to a set amount to make sure your card works. After you finish filling up, you only pay for what you actually bought — the extra amount is released later by your bank. If you want to avoid this, pay inside at the till instead of paying at the pump.
- What's the difference between fuel and super unleaded?
- Super unleaded is a higher-quality fuel for some engines. Some cars are designed to run best on it, but many cars are fine on normal fuel. Super unleaded usually costs more.
- Should I use super unleaded or normal fuel?
- Follow what your car handbook says. If it recommends super unleaded, using it can improve performance and fuel economy for that engine. If your car is designed for normal fuel, super unleaded usually isn't worth the extra money.
- Can I mix super unleaded and normal fuel?
- Yes — mixing is normally fine. Your car will run on the mix in the tank. Just make sure your car is compatible with normal fuel if you plan to use it regularly.
- Is there a best time of day to buy fuel or diesel in Cardiff?
- Yes, there typically is. Data suggests that midweek (especially Wednesday) often sees the lowest prices as demand dips. Buying during off-peak hours — like early morning or late at night — can also yield savings, as demand is lower and some stations adjust prices. Avoid weekends and late Friday afternoons, when prices often peak. In Cardiff, local competition between stations is the biggest factor, so always use the Resolvo map to check the current live prices before heading out.
- Why are prices different at two stations from the same brand in Cardiff?
- Even if the brand name is the same, stations in Cardiff can be run by different operators and have different costs (rent, staff, delivery costs). They also react to different local competitors. So prices can vary a lot even within the same brand.
- Why can't I find a specific fuel station on the map in Cardiff?
- It may not be included in the available data yet, it may not be reporting prices consistently, or it may be temporarily closed. Try searching nearby areas on the Resolvo map, or check back later as coverage improves.
- Do prices include loyalty discounts or vouchers?
- Usually no. The map price is normally the standard price. Some stations offer discounts through loyalty cards or apps, which can make the pump price lower for some drivers.
- I got a parking ticket — can Resolvo help with that too?
- Yes. Resolvo also has tools to help with parking and PCN appeals in Cardiff. If you've received a ticket, you can use the appeals tool to understand your options and prepare an appeal based on your situation.
- Can Resolvo help me check a car before I buy it?
- Yes. Resolvo has a suite of vehicle check tools that let you quickly check a car's status. You can use our MOT Checker to see test history, our Road Tax Checker for VED costs, our Emissions Checker for CO₂ data, and our ULEZ Checker to see if you'll face clean air zone charges. This helps you avoid expensive surprises before you buy.
