Cheapest Cars to Insure: What to Buy (and Avoid)
A UK guide to the cheapest cars to insure, how insurance groups work, and a shortlist of models that tend to keep premiums sensible.
If you’re shopping for a new (or first) car, there’s one cost that can make a “bargain” feel expensive very quickly: insurance. The good news is that there are patterns behind the pricing. The best news is that you can use those patterns to narrow your search to the cheapest cars to insure, before you fall in love with a model that insurers don’t.
This guide is UK-focused and built for real-world car buying. We’ll explain how insurers price cars, what “insurance groups” actually tell you, and a shortlist of models and features that typically keep premiums sensible.
Cheapest Cars to Insure: The Quick Take
If you want the short version, look for cars that are:
- In lower insurance groups (often smaller, lower-powered trims).
- Cheap and quick to repair (common parts, simpler tech, smaller body panels).
- Harder to steal (good security, not a high-theft target).
- Driven by lower-risk demographics (some sporty trims get priced up because of claim patterns, even if the engine is modest).
That’s why the “usual suspects” are often small hatchbacks and superminis. But model choice is only half the story. Your details and the policy setup can swing the price just as much.
How Car Insurance Pricing Works (and Why Two People Pay Different Prices)
UK insurers price risk using a mix of driver factors (age, licence type, claims and convictions, occupation), location factors (postcode, where you keep the car overnight), and vehicle factors (repair costs, performance, theft risk, safety tech).
That’s why “the cheapest cars to insure” is always a tendency, not a promise. Two drivers in different postcodes can see very different quotes for the same car.
If you want a plain-English breakdown of how cover works and the terms to watch, MoneyHelper has a solid primer on car insurance and how to cut costs.
What Are Car Insurance Groups in the UK?
Insurance groups are a way of ranking cars by risk, typically from Group 1 (lowest) to Group 50 (highest). Lower group usually means cheaper insurance, but it’s not the only input.
Groups reflect things like repair costs, performance, parts prices, safety and security features, and how likely the car is to be stolen or involved in claims. The system is designed so insurers can start from a baseline expectation for that vehicle type.
If you want the background on how group ratings are set, Thatcham Research (which is involved in vehicle risk research) explains the idea behind the vehicle group rating approach and broader safety and repairability work.
Cheapest Cars to Insure: Models That Often Price Well
Rather than listing a single “winner”, here’s a shortlist of models that often sit in the value zone for insurance, especially in smaller engine trims. Always check the exact variant (engine size and trim can move a car into a higher group).
Small City Cars and Superminis
- Hyundai i10 (smaller engine trims)
- Kia Picanto
- Toyota Aygo / Aygo X
- Volkswagen up! / Skoda Citigo / SEAT Mii (where available used)
- Fiat Panda
Small Hatchbacks (Often Good All-Rounders)
- Volkswagen Polo (lower-powered trims)
- Skoda Fabia
- SEAT Ibiza
- Ford Fiesta (watch sporty trims and higher power)
- Vauxhall Corsa (quotes vary by trim and driver profile)
Important: insurers can price the same “model” very differently depending on the exact version. A 1.0-litre entry trim and a sporty 1.0 turbo with larger wheels and body kit may not land in the same value bracket.
What to Avoid If You Want Cheap Insurance
Some cars attract higher premiums because the risk profile is higher in the data, even if the car is not “fast” in the way people think. Common premium-raisers include:
- Hot hatch or sporty trims (ST, RS, GTI, VXR, “Sport” packages)
- Large alloy wheels and low-profile tyres (more expensive to replace, more damage claims)
- High theft-target models in your area
- Rare cars with expensive parts (even if the purchase price is low)
- Heavily modified cars (and undeclared mods are a big risk)
How to Check if a Specific Car Will Be Cheap to Insure
Before you buy, do a quick quote test. It takes 10 minutes and can save you hundreds.
- Pick 3–5 cars you’re genuinely willing to buy.
- Quote each car with identical details (mileage, job title, parking, cover level).
- Save the quote PDFs / screenshots and compare like-for-like: excess, add-ons, included extras.
Tip: if you’re approaching renewal, our guide on the best time to renew car insurance explains why starting early can reduce quotes.
Small Changes That Can Reduce the Premium (Without Changing Car)
If you already own a car and the quote is painful, try adjusting the levers you control:
- Increase the voluntary excess (only to a level you could comfortably pay if you claim).
- Re-check your job title wording (be truthful, but use the closest standard option).
- Review mileage. Overestimating can push the price up.
- Park off-street if you can (driveway/garage options can price differently).
- Cut unnecessary add-ons if you already have them elsewhere (breakdown, legal cover).
If you’re unsure what’s truly essential, start with the renewal checklist in our car insurance renewal guide.
Comprehensive vs Third Party: Is Comprehensive Always More Expensive?
No. It sounds backwards, but comprehensive cover can sometimes come out similar to third party (or even cheaper). That’s because insurers price based on the overall risk profile of the policyholder group, not just the cover level.
So it’s worth quoting both and checking what you’re actually getting. Just make sure you compare the same excess and add-ons.
Don’t Risk a Gap in Cover
Driving uninsured is serious, and the knock-on effects can be expensive. If you’re switching, make sure your new policy starts exactly when the old one ends. GOV.UK explains the rules around keeping your vehicle insured (continuous insurance enforcement).
Make Your Car Search Cheaper to Insure: A Simple Buying Checklist

- Prefer common, repair-friendly models.
- Avoid sporty styling packages if the goal is low premiums.
- Keep modifications minimal and declared.

Frequently Asked Questions
What are the cheapest cars to insure in the UK?
The cheapest cars to insure are usually small, lower-powered models that sit in lower insurance groups and have plentiful, lower-cost parts. In practice that often means superminis and small hatchbacks (for example, 1.0–1.2 litre variants) with a clean security and safety record.
Are insurance groups the only thing that matters?
No. Insurance group is a useful shortcut, but your quote is also shaped by your age, driving history, postcode, mileage, where the car is kept overnight, how you pay, and the exact cover and excess you choose.
Is a smaller engine always cheaper to insure?
Often, but not always. Smaller engines tend to have lower performance and may sit in lower groups, but insurers also price based on claim frequency, repair costs, theft risk, and how often certain models are involved in accidents.
Does choosing third party cover make insurance cheaper?
Not necessarily. Comprehensive cover can sometimes be similar in price (or even cheaper) because insurers’ pricing reflects the overall risk profile, not just the level of cover.
How can I make a car cheaper to insure?
Start quotes early, compare like-for-like cover, consider increasing the voluntary excess to a level you can afford, keep modifications declared and minimal, park off-street if you can, and add an experienced named driver only if it’s truthful and reflects the main driver correctly.
