Tesco vs BP: which is cheaper?
Today’s head-to-head on price, network size and coverage, read live from every Tesco and BP forecourt reporting to the government Fuel Finder scheme.
Tesco is cheaper today
Tesco is averaging £1.69 a litre for petrol against £1.73 at BP — 4.0p a litre, £2.20 on a 55-litre tank. On diesel the gap is 5.0p and Tesco leads. These are medians across each whole network, so treat them as the shape of the market rather than a promise about the forecourt at the end of your road.

The row worth dwelling on is the spread. Tesco sites range across 19.0p and BP across 38.0p. Both are far wider than the gap between the two brands, which is the whole argument for checking the forecourt rather than trusting the sign — see what is actually near you.
How the gap has moved
Daily network averages for both chains, on one scale.
Where each brand actually is
Forecourts by UK region. A cheaper chain is only cheaper if it has a site near you.
Coverage shape explains most of what looks like a price difference. Fuel is cheaper in some regions than others regardless of brand, so a chain weighted towards the cheaper ones shows a lower national average without any of its sites pricing unusually. Compare the regions to see how large that effect is.

Which should you use?
On today’s numbers Tesco wins the national comparison by 4.0p. Over a year of fortnightly fills that is £57 — real money, but less than the difference between a well-chosen and a badly chosen forecourt of either brand. The question that does decide it is distance. A litre saved is only worth having if you did not burn the saving getting there: the break-even calculation is a single division, and for most cars a detour of more than a couple of miles eats a two-pence saving whole.
Both carry loyalty schemes — Clubcard points on fuel and BPme Rewards — which shift the effective price by an amount that depends on how much you redeem rather than how much you fill. Beyond that, the fuel itself is the same specification at both — what actually differs between supermarket and branded fuel is the additive package, not the base product.

Common questions
Is Tesco or BP cheaper for petrol?
Tesco is cheaper today, at £1.69 a litre against £1.73 — a difference of 4.0p, or £2.20 on a 55-litre tank. Those are medians across each network, so an individual forecourt near you can easily reverse the order.
How much would switching between Tesco and BP save in a year?
On today's difference of 4.0p a litre, a driver filling a 55-litre tank once a fortnight would save about £57 a year — £2.20 a fill. That assumes the gap holds, which it does not always: the ranking between two chains can swap within a month.
Does Tesco fuel differ from BP fuel?
Standard E10 petrol and B7 diesel are the same specification wherever you buy them — they meet the same British Standard, and are frequently refined and delivered by the same companies regardless of the sign on the forecourt. What differs is the additive package blended in at the terminal, which is where premium grades and branded formulations come in. For an ordinary car on ordinary journeys, the manufacturer's handbook is the authority on whether that is worth paying for.
Which has more forecourts, Tesco or BP?
BP has more: 1079 forecourts currently reporting a price against 511. Tesco covers 12 of the twelve UK regions and BP covers 12. Network size matters more than the headline price for most drivers — a chain that is two pence cheaper but forty minutes away is not cheaper.
How often are these prices updated?
Both chains report every price change to the government Fuel Finder scheme, which has required a report within thirty minutes of a change taking effect since February 2026. The figures here refresh throughout the day from that feed.
