Are electric cars cheaper than petrol or hybrid cars?

Are electric cars cheaper than petrol or hybrid cars in the UK in 2026? On monthly PCP cost, in 7 out of 10 like-for-like comparisons — yes, either cheaper or level pegging. On upfront list price, not yet. But the gap has all but closed in the segments where it matters, and in one stand-out case an EV that costs £3,175 more on the forecourt now costs £181 a month less on PCP than its plug-in hybrid sibling. Here’s what our latest research actually shows.

Quick answers:

• Cheaper to run than petrol? Yes — typically two to three times cheaper per mile on home electricity.
• Cheaper on monthly PCP? In 7 of 10 like-for-like UK pairs in our April 2026 data.
• Cheaper than a hybrid? Often, yes — and by as much as £181 a month in our standout pair.
• Cheaper to buy outright? Not yet — but the gap has all but closed.

The headline finding: an EV that costs £3,175 more is £181 a month cheaper

The standout pair in our April 2026 dataset is the Audi Q6 e-tron against the Audi Q5 Sportback plug-in hybrid. The Q6 starts £3,175 more expensive on list price. After discounts — £12,025 off the Q6 versus £6,989 off the Q5 — the EV ends up £181 a month cheaper to run on PCP. That isn’t a freak result. It’s the clearest version of a pattern that runs right through the data.

EV vs petrol vs hybrid: what the UK 2026 data shows on cost

This Insider Car Deals research, drawn from our April 2026 monthly index, compares ten like-for-like pairs — the EV version of a model against its closest petrol, hybrid or diesel sibling within the same manufacturer’s range. We’ve used Insider Car Deals’ Target Price for each (the price our research says a buyer should actually pay, not the sticker price), the total saving in pounds and percentage, and the resulting monthly PCP figure.

In 7 of those 10 pairs, the EV is either cheaper than or level with the petrol or hybrid equivalent on monthly PCP cost. In 6 it’s outright cheaper. In one it’s tied. In three it’s dearer, and never by more than £39 a month.

That is a very different market from even two years ago, when EVs routinely cost £80–£150 a month more than their combustion siblings on PCP. The shift has been steady — last summer our research found family EVs were already £46 a month cheaper than the year before — and April 2026’s data shows that gap has now closed entirely against petrol and hybrid in most pairs. The shift hasn’t been driven by list prices falling; it’s been driven by manufacturers loading more discount and more deposit contribution onto their EVs to keep volume moving — confirming what our wider research has shown for some time, that there’s more room to negotiate new-car pricing than most buyers realise.

Going through it segment by segment

Small car: Dacia Spring EV vs Sandero Stepway petrol

Dacia is determined to win the small car battle, with a low start price, generous discounts and an interest-free PCP on the Spring. Result: the EV undercuts the petrol Sandero Stepway by £50 a month.

Small hatch: Fiat Grande Panda EV vs Hybrid

Fiat’s Grande Panda is the cleanest illustration of how the maths now works. The EV is almost £2,000 more expensive than its hybrid sibling on list price, but a bigger total discount and a lower PCP APR mean it costs £10 a month less to own.

Supermini: Peugeot e-208 vs 208 Hybrid

Peugeot is the exception that proves the rule. A bigger total saving on the e-208 doesn’t quite outweigh the higher list price because Peugeot has chosen to keep the PCP APR at 6.9% on both the EV and the hybrid. The e-208 ends up £8 a month dearer than the petrol-hybrid 208.

Family hatch: VW ID.3 vs Golf — is the EV cheaper?

This is where the EV advantage is most obvious. Volkswagen is throwing real money at the ID.3 to build EV market share, and the result is a £71 a month cost advantage over the Golf — on cars at near-identical list prices.

Compact crossover: Ford Puma Gen-E vs Puma Hybrid

The Ford Puma Gen-E qualifies for the maximum £3,750 government EV grant currently available in the UK. That, combined with a deeper discount, delivers a £25 a month advantage over the petrol-hybrid Puma.

Family SUV: VW ID.4 vs Tiguan

The ID.4 starts £4,450 more expensive than the Tiguan, but VW’s intent to push EV volume drags it down to monthly price parity with the petrol Tiguan at £362.

Large SUV: Skoda Enyaq vs Kodiaq

Skoda is offering buyers a straight choice between Enyaq EV and petrol Kodiaq with the monthly PCP figures within £3 of each other. The Enyaq pulls ahead overall because it’s offered on a 3-year PCP at zero interest.

Premium coupe: BMW i4 vs 4-Series

BMW is hedging its bets here. A bigger total discount on the petrol 4-Series Gran Coupe and a lower PCP APR on the i4 leave the EV £39 a month more expensive. Buyers will need a reason beyond cost to pick the i4.

Premium SUV: Audi Q6 e-tron vs Q5 plug-in hybrid

The standout of the dataset. The Q6 e-tron starts £3,175 more expensive than the Q5 Sportback plug-in hybrid and ends up £181 a month cheaper. That’s the kind of outcome that ought to make any premium SUV buyer at least look at the EV option.

Luxury SUV: BMW iX vs X5 diesel

The BMW iX is a remarkable £8,330 more expensive than the X5 40d on list price, yet costs £90 a month less on PCP. The discount level on the iX — £19,451, or 20.9% — is doing almost all of that heavy lifting.

Why are EVs now cheaper than petrol on monthly cost?

Three forces are running at once. PCP shifts the residual value risk to the finance company, not the buyer, so what matters to most people is the monthly figure rather than the sticker — that’s running cost, fuel cost and depreciation rolled into one number. Manufacturers are deposit-contributing more aggressively on EVs than on petrol or hybrid models, because they need EV volume — both for ZEV mandate compliance and to compete with the wave of new entrants. And the £4.7 billion of total UK new car discount this year is being spread disproportionately towards electric: EVs are around 29% of sales but pulling roughly £1.6 billion of the discount pot, with an average new EV discount of £6,892, or 12.5%, against a market average of £5,877, or 11.3%. Our research late last year showed median EV prices had already dropped £4,581 year-on-year, and the trend has continued.

Are electric cars cheaper than petrol cars to buy? Not yet — but the gap is closing

We need to stay clear-eyed. On upfront list price, EVs are still typically more expensive than petrol or hybrid equivalents — and petrol and hybrid discounts have themselves been strengthening, which keeps the buy-price gap real. That’s true in 9 of the 10 pairs in our dataset — sometimes by £250, sometimes by £8,330. List-price parity is not here yet.

But the metric most buyers actually use is the monthly figure, and on that measure the question has flipped. The right question for a 2026 buyer is no longer “can I afford the EV?” — it’s “is there a reason I’d pay more per month for the petrol or hybrid version?”

Why the EV tipping point will be driven by better deals, not green messaging

The market is converging. As a result, we’re moving towards a point where the EV debate fades and electric cars become either a competitive default or an aspirational choice against petrol and hybrid alternatives. That kind of normalisation usually comes just before a tipping point.

Green messaging alone won’t get us there. People don’t respond well to being told what to do, or what’s better for the planet. They respond to a better deal. The April 2026 data says they’re now getting one.

Frequently asked questions: are electric cars cheaper than petrol or hybrid cars?

Are electric cars cheaper than petrol cars to run in the UK?

Yes. On home electricity, electric cars are typically two to three times cheaper to fuel per mile than equivalent petrol cars, and servicing costs are lower because EVs have far fewer moving parts. Public rapid charging narrows the gap, but for the majority of UK drivers who can charge at home, EVs remain materially cheaper to run than petrol or hybrid cars.

Are electric cars cheaper than hybrid cars?

On monthly PCP cost, electric cars are now cheaper than hybrid equivalents in most like-for-like comparisons within the same manufacturer’s range. The Audi Q6 e-tron costs £181 a month less than the Q5 Sportback plug-in hybrid in our April 2026 research, despite a £3,175 higher list price. The Fiat Grande Panda EV is £10 a month cheaper than the Grande Panda hybrid.

Are electric cars cheaper than diesel cars?

On monthly PCP cost, yes — at least in the luxury SUV segment our research covers. The BMW iX EV costs £660 a month against £750 a month for the BMW X5 40d diesel — a £90 a month advantage to the EV — even though the iX is £8,330 more expensive on list price than the diesel X5.

Are EVs cheaper on PCP than petrol cars?

In 7 of 10 like-for-like comparisons in our April 2026 dataset, the EV is cheaper or level on monthly PCP than the petrol, hybrid or diesel equivalent. PCP shifts residual value risk to the finance company, and manufacturers are deposit-contributing more aggressively on EVs than on combustion models, which pulls the monthly figure down.

Which EV beats its petrol equivalent by the biggest monthly margin?

The Audi Q6 e-tron, in our April 2026 research, costs £181 a month less than the Audi Q5 Sportback plug-in hybrid — the standout result in the dataset. The BMW iX (£90 a month cheaper than the X5 40d) and the VW ID.3 (£71 a month cheaper than the Golf) come next.

Is an electric car worth it in 2026?

For most UK buyers who can charge at home, yes. On monthly PCP cost, EVs now match or beat petrol or hybrid equivalents in 7 of 10 like-for-like cases. On running cost, EVs are typically two to three times cheaper per mile. The case is weakest for high-mileage drivers without home charging, and for buyers paying cash who care most about list price.

Should I buy an EV or a petrol car in the UK?

If you can charge at home and you finance via PCP, the EV is now the cheaper option in most cases. If you can’t charge at home, drive very high mileage, or are buying outright with cash, the petrol or hybrid version may still make more sense. The honest answer is to compare the specific pair you’re considering on monthly PCP, not list price.

What is the average discount on a new electric car in the UK?

The current average discount on a new EV in the UK is £6,892, or 12.5% off list price. That compares with a market-wide average of £5,877, or 11.3%, across all fuel types. EVs are pulling roughly £1.6 billion of the £4.7 billion total UK new car discount pot.

Will electric cars become cheaper than petrol cars to buy?

The direction of travel is clear: discount levels on EVs are widening faster than on petrol or hybrid cars, Chinese entrants are forcing list prices down, and battery costs continue to fall — our own data shows EV prices have dropped £3,750 in a year at the median. On upfront list price, parity is not here yet. On monthly PCP cost, electric cars are already cheaper than petrol or hybrid equivalents in most cases.
