Best First Cars Low Road Tax — Dave Recommends

The Hidden Cost That Catches New Drivers Off Guard

road tax -- or Vehicle Excise Duty as the government officially calls it -- is one of those running costs that New Drivers often forget to budget for until the reminder drops through the letterbox. And depending on what car you buy, it can range from absolutely nothing to well over £500 per year. That is a significant chunk of money for someone who has just spent their savings on a First Car.

The good news is that road tax on most small cars is extremely low, and on several of the cars I am about to recommend, it is zero. Literally free. The government charges nothing to tax them because their CO2 emissions are so low. For a new driver watching every penny, that is money you can redirect towards insurance, fuel, or building up a maintenance fund.

This guide examines exactly how road tax is calculated in the UK, which CO2 bands matter, and which five First Car Insurance Tips covers similar ground from a different angle.

Cars Registered On or After 1 April 2017

The rules changed significantly for cars registered from April 2017 onwards. There is now a flat standard rate of £190 per year for all petrol and diesel cars, regardless of CO2 emissions. The only exception is zero-emission vehicles (fully electric), which pay nothing.

However, the first-year rate is still based on CO2 emissions. A car emitting 1-50 g/km pays £10 in its first year. A car emitting 51-75 g/km pays £30. A car emitting 76-90 g/km pays £135. A car emitting 91-100 g/km pays £175. From 101 g/km upwards, the first-year rate climbs steeply.

This means that if you are buying a used car registered after April 2017, you will pay £190 per year regardless of how efficient it is (unless it is electric). The CO2 figure only affected the first keeper's bill. However, if you buy a pre-April 2017 car, the CO2-based rate applies to you for the entire life of the vehicle.

The Strategic Implication for First Car Buyers

Here is the data-driven conclusion. If minimising road tax is a priority, you should specifically target cars first registered before 1 April 2017 with CO2 emissions of 100 g/km or below. These cars are free to tax every single year, indefinitely. That is a guaranteed saving of at least £190 per year compared to an equivalent post-2017 car.

All five cars below are available in pre-2017 versions that qualify for free road tax.

1. Suzuki Celerio -- £0 Road Tax, £0 Fuss

The Suzuki Celerio is the undisputed champion of low running costs. The 1.0-litre Dualjet engine produces just 84 g/km of CO2, which places it firmly in Band A/B territory for pre-2017 models. Road tax: £0 per year.

But the Celerio does not just win on tax. It is also the most fuel-efficient non-hybrid petrol car you can buy. The official combined figure is 65.7 mpg, and in real-world driving, owners consistently report 55-60 mpg. Over 10,000 miles per year at current fuel prices, that translates to an annual fuel bill of approximately £900-£1,000. Compare that to a typical supermini at £1,200-£1,400, and the Celerio saves you around £300-£400 per year on fuel alone.

For more on this topic, take a look at our Best First Cars with Low Running Costs guide.

Combine the zero road tax with the exceptional fuel economy, and the Celerio's total annual running cost (excluding insurance) is among the lowest of any car on sale. insurance groups range from 3 to 5, which also keeps premiums modest for new drivers.

The Celerio is not glamorous. The interior is functional rather than fashionable, and the driving experience is adequate rather than exciting. But when you add up the numbers, no other petrol car comes close to matching its cost-effectiveness.

Typical price: a 2016 Celerio SZ3 with 30,000 miles costs around £3,500 to £5,000.

2. Citroen C1 -- Zero Tax With a Dash of Character

The Citroen C1 equipped with the 1.0-litre VTi engine produces 95 g/km of CO2 in pre-2017 form. That falls within the zero-tax bracket, making it another free-to-tax option for budget-conscious new drivers.

The C1 has been a consistent favourite in my first car recommendations because it ticks so many boxes simultaneously. It is cheap to buy, cheap to insure (groups 3-7), cheap to fuel (50-55 mpg in real-world driving), and now we can confirm it is free to tax as well. The total cost of ownership over three years is genuinely difficult to beat.

What sets the C1 apart from the Celerio is its availability. Citroen sold enormous numbers of C1s in the UK, which means there are plenty to choose from on the used market. That buyer's market keeps prices competitive and means you can afford to be selective about mileage, condition, and specification.

The C1 is also mechanically identical to the Toyota Aygo, sharing the same Toyota-designed 1.0-litre engine that has proven to be outstandingly reliable across millions of miles of real-world use. Parts availability is excellent and servicing costs are minimal.

Typical price: a 2016 C1 Feel with 35,000 miles costs around £3,800 to £5,500.

3. Peugeot 108 -- The Stylish Zero-Tax Option

The Peugeot 108 completes the trio of cars built on the shared Toyota-PSA platform. Like the C1 and Aygo, it uses the same 1.0-litre engine producing 95 g/km CO2, qualifying for zero road tax on pre-2017 models.

So why include it separately? Because the 108 offers a slightly different ownership experience. Peugeot positioned it as the most premium of the three, with better interior trim, a more sophisticated design, and features like a seven-inch touchscreen that was not available on the base C1 or Aygo.

The 108 also holds its value slightly better than the C1 but slightly less than the Aygo, placing it in a middle ground that often makes it the best value of the three when buying used. Buyers gravitate towards the Toyota badge, pushing Aygo prices up, while the C1 sometimes suffers from a perception of being the budget option. The 108 quietly sits between them, often offering the best specification for the money.

Insurance groups mirror the C1 at 3-7, and fuel economy is identical at 50-55 mpg in real-world use. The Allure and GT Line trims add reversing cameras, leather steering wheels, and climate control, which are nice touches in a car that costs under £5,000 used.

Typical price: a 2016 108 Allure with 30,000 miles costs around £4,000 to £5,800.

4. Volkswagen Up -- German Engineering, British Savings

The Volkswagen Up (styled as "up!") brings something different to this list: a sense of quality and engineering precision that the budget options above cannot quite match. The 1.0-litre three-cylinder engine in the pre-2017 Up produces 95-100 g/km CO2 depending on the variant, placing most models in the zero-tax bracket.

The Up feels noticeably more solid than its rivals. The doors close with a satisfying thunk, the cabin materials are a clear step above, and the driving experience has a composure and refinement that justify the slight premium over the Celerio or C1. The engine is eager and characterful, the gearbox action is precise, and the chassis handles bumps and corners with equal competence.

We have covered related ground in our Safest First Cars Ncap guide, which is worth reading if this subject interests you.

Fuel economy sits at 50-58 mpg in real-world driving, and insurance groups range from 1 to 8 depending on the variant. The Move Up, Take Up, and High Up trim levels offer increasing levels of equipment, with the High Up including heated seats, cruise control, and a colour touchscreen.

The Up also spawned two closely related siblings: the SEAT Mii and Skoda Citigo. All three share the same mechanical package, and the SEAT and Skoda versions are typically £500 to £1,000 cheaper used. If you want Up quality at an even lower price, those two are worth investigating.

What to Watch For

The Up's maps and infotainment relied heavily on a companion smartphone app called Maps + More, which Volkswagen has since discontinued. This means the sat nav functionality on older models is effectively non-functional. Factor in the cost of a phone mount and use your smartphone for navigation instead.

Typical price: a 2016 Up High Up with 35,000 miles costs around £4,500 to £6,000.

5. Dacia Sandero -- Zero Tax in a Bigger Package

The Dacia Sandero breaks the mould on this list because it is not a city car. It is a full-size supermini -- roughly the same dimensions as a Ford Fiesta -- but the 0.9-litre TCe engine in pre-2017 models produces just 99 g/km CO2. That scrapes into the zero-tax band, making the Sandero the largest and most practical car on this list that you can tax for free.

Dacia's entire business model is based on stripping out unnecessary cost and passing the savings to the buyer. The Sandero does not have the latest touchscreen technology, the most fashionable interior trim, or the sharpest marketing campaign. What it does have is a usable back seat, a 320-litre boot, a willing turbocharged engine, and a price tag that undercuts every comparable rival by a significant margin.

New Sanderos start from around £7,000 -- the cheapest new car on sale in the UK. Used examples of the first-generation model (2013-2020) with the 0.9 TCe engine are available from as little as £2,500 to £4,500, making it the cheapest car to acquire on this list in absolute terms.

The FCA has a useful guide to car finance that explains your rights and what to watch for.

Insurance groups range from 5 to 11, and fuel economy sits at 45-52 mpg in mixed driving. The Sandero will not wow you with its refinement, but it will transport you, your passengers, and your luggage in reasonable comfort for remarkably little money.

What to Watch For

Dacia uses a lot of Renault-sourced components, and reliability is generally good. The 0.9 TCe engine is shared with the Renault Clio and has a solid track record. However, the build quality of the interior is basic -- expect hard plastics, simple controls, and a general sense of austerity. That is the trade-off for the low price.

Typical price: a 2016 Sandero Laureate TCe 90 with 40,000 miles costs around £3,000 to £4,500.

Annual Cost Comparison Table

To put these figures in context, here is what a new driver might expect to pay annually for each car, based on 8,000 miles of mixed driving.

The Suzuki Celerio delivers approximately £0 road tax, £720 fuel cost, and £130 for servicing, totalling around £850 annually. The Citroen C1 is similar at £0 road tax, £780 fuel cost, and £140 servicing for roughly £920 per year. The Peugeot 108 matches the C1 at approximately £920 annually. The Volkswagen Up costs around £0 road tax, £800 fuel, and £160 servicing for £960 per year. The Dacia Sandero sits at £0 road tax, £840 fuel, and £150 servicing for approximately £990 annually.

Compare those figures to a typical 1.2-litre supermini registered after April 2017, which would cost £190 in road tax alone before you even consider fuel and servicing. Over three years, the road tax saving on a pre-2017 zero-band car amounts to £570. That is not a trivial sum for a first-time driver.

Dave's Data-Driven Verdict

The numbers do not lie. If you want the absolute lowest road tax bill, any of these five cars registered before April 2017 will cost you precisely nothing in VED. The Suzuki Celerio wins on overall running costs, the Dacia Sandero offers the most car for the money, and the Volkswagen Up provides the best driving experience.

But here is my final piece of advice, and it is just as important as everything above. The cheapest car to tax is worthless if it has hidden problems. Before you buy any used car, check its full history through Dave's vehicle check. Verify the mileage is genuine, confirm there is no outstanding finance, check for insurance write-off markers, and review the complete MOT history. A car that saves you £190 per year on road tax but costs £2,000 in hidden repairs is not a bargain -- it is a liability. Check first, then buy with confidence.
