What Happened

The question of what a new car should cost has been circulating in motoring media again, prompted by a reader debate piece by Michael Strong on The Truth About Cars published on 25 September 2026. That article is a US-focused opinion prompt, not a data release or policy announcement, and it contains no UK figures. But the question it raises is a fair one for British buyers too.

So here are the actual UK numbers.

IBISWorld, drawing on ONS Consumer Price Index data, puts the UK new car price index at 139 in 2026, against a base year of 2015 equalling 100. That represents annualised growth of 3.6% between 2021 and 2026. In plain terms, a car that cost £20,000 in 2015 would need to be priced at roughly £27,800 today just to keep pace with that index.

A January 2026 analysis of ONS data by NimbleFins found that new car prices are up approximately 40% over the past ten years since 2015. For context, used car prices rose just 14% over the same period. Since 2020, GEM Motoring Assist puts the rise at around 25% based on CPI data, while industry figures from Auto Trader and NimbleFins suggest the increase in asking prices is closer to 30 to 40%.

Both can be true at the same time. CPI measures a broad basket of goods. Auto Trader measures what dealers are actually asking. The gap between those two numbers tells you something about where the pressure on buyers is being felt.

The main drivers behind these rises are semiconductor shortages, supply chain disruption, general inflation and rising production costs. The pound’s weakness since 2016 has also pushed up the cost of imported vehicles, which make up the majority of UK sales. Electric and hybrid models cost more to build, and as they take a larger share of the market, average prices are pulled upward.

These are on-the-road (OTR) starting list prices for base-trim models, meaning the lowest published price including delivery, number plates, road tax and first registration fee. They are not average transaction prices. No single official UK source publishes an average transaction price.

According to NimbleFins, small cars in the B-segment now start from around £19,725 for a base Vauxhall Corsa, £22,040 for a VW Polo Life and £26,580 for a Ford Puma, giving an average starting price among those three of roughly £22,782. The cost of a cheap new small car has risen nearly 50% since 2020.

In the C-segment, a Skoda Octavia starts from £28,490, a VW Golf Life from £28,895 and a Vauxhall Astra Griffin from £26,135, averaging around £28,840. Ford stopped UK production of the Focus in November 2025, so it no longer features in this comparison.

SUVs, which now dominate UK sales, typically start above £30,000, with electric and premium examples pushing well past £40,000.

For comparison, the US average new vehicle transaction price crossed $50,000 for the first time in 2026, according to Kelley Blue Book data. That figure is pulled upward by large pickups and premium SUVs. It is a US dollar figure in a different market and cannot be directly compared to UK OTR prices.

Who It Affects

Anyone buying a new car in the UK right now is paying significantly more than they would have five or ten years ago. The private buyer is hit hardest. Of the 2,020,520 new cars registered in the UK in 2025, only 38.6% were private registrations. Fleet and business buyers accounted for the rest, and they often access different pricing structures.

Buyers who cannot stretch to a new car and turn to the used market face a different set of pressures. Auto Trader data from August 2026 shows that cars aged 10 to 15 years recorded like-for-like asking price growth of 6.9% year on year. That is the strongest growth of any age group. Cheaper older cars are getting more expensive because pandemic-era production gaps are now reducing the supply of five to six year old cars, with Auto Trader warning of a 25 to 30% volume drop in that bracket during 2026.

Used EV prices have moved in the opposite direction, falling around 9% year on year to an average of roughly £22,174 by March 2026. That makes a used electric car an increasingly realistic option for budget-conscious buyers. Our guide to charging an electric car at home covers the practical side of that decision.

Motor Mike Analysis

The short version: new cars cost more because everything that goes into building and selling them costs more, and the shift to electric has added another layer of expense on top. That is not a conspiracy. It is arithmetic.

What concerns me more is the finance side. The Bank of England held its base rate at 3.75% in February 2026, but market signals since then have shifted. Swap rates and gilt yields have already risen, and further cuts to the base rate look less certain than they did at the start of the year. That matters because a 1 percentage point rise in APR on a £20,000 finance agreement adds roughly £420 to £480 to the total cost. On a £15,000 agreement, that same rise costs you around £300 to £350 more overall.

Typical APRs in 2026 run from 5 to 9% on new car manufacturer deals, 8 to 14% on used car finance, and 5 to 8% on personal bank loans above £7,500. If you can borrow on a personal loan at the lower end, it is worth comparing that against dealer finance before you sign anything.

The used market deserves serious attention. Average used car retail prices ended 2025 at £17,018 and have been broadly flat since. Older cars are getting pricier, but the market overall has not spiked. If you are flexible on age and mileage, you can still find value. Our used car test drive checklist will help you approach that sensibly.

What Is Still Unclear

There is no single published UK average transaction price from SMMT, ONS or any other official primary source. All the segment prices above are OTR starting list prices, not what buyers typically pay after negotiation, part exchange or finance deals. Treat them as the floor, not the average.

A car finance mis-selling redress scheme has been discussed, with industry estimates suggesting average compensation of around £700 per affected agreement, potentially covering around 14 million agreements taken out between April 2007 and November 2024. Those figures come from industry commentary, not confirmed FCA guidance. The final scheme rules have not been published. Check the FCA website at fca.org.uk for the current official position before acting on any claim about eligibility or compensation.

SMMT monthly registration data for 2026 year to date should also be checked at smmt.co.uk for the most current figures, as the market picture may have shifted since the data cited here.

What to Do Now and What to Watch Next

If you are in the market for a new car, decide whether you genuinely need new. The used market at present offers better value per pound, particularly for conventional petrol and diesel cars. Used EVs are falling in price and worth a close look if home charging is practical for you.

If you are buying new, get quotes from at least three dealers and check whether a personal loan beats dealer finance for your credit profile. Run the numbers before the showroom, not during it.

Watch the Bank of England base rate decisions. If rates rise, the cost of any variable rate or new finance agreement goes up with them. Lock in a fixed rate if you can.

If you took out car finance between April 2007 and November 2024, monitor the FCA’s official announcements on the mis-selling redress scheme at fca.org.uk. Do not pay a claims management company to pursue this on your behalf until the official process is confirmed and you understand whether you need one.
