Mazda CX-30 Insurance Cost UK (2026)

A Mazda CX-30 costs roughly £760 a year to insure comprehensively in 2026 on our composite, with the compact SUV sitting in insurance groups 12–21 — reassuringly low for an SUV, and only a little above the UK all-cars average. The entry petrol trims are the ones that keep it cheap.

Direct answer

What does it cost to insure a Mazda CX-30?

Our composite puts a typical fully comprehensive Mazda CX-30 premium at around £760 a year, or roughly £68 a month paid monthly. There's a caveat worth being straight about: Finder doesn't publish a standalone CX-30 figure the way it does for the Mazda 3, so we've benchmarked to the closely related Mazda CX-3 (£770 a year) and nudged it down slightly, because the CX-30 sits in lower insurance groups than the CX-3. Either way it lands a touch above the roughly £600 all-cars figure on our UK cost index, between the ABI's £566 average premium actually paid in Q2 2026 and the £719 average quoted on the Confused.com Price Index.

For an SUV, that's a genuinely sensible number — and it's mostly down to where the CX-30 lands on the group scale. Four things shape it:

Insurance group. Per Parkers, the CX-30 runs from group 12 to group 21 on the 1–50 scale. The 2.0 e-Skyactiv-G mild-hybrid petrol in SE-L and Sport Lux trim sits right at the bottom (groups 12–13); the more powerful 2.0 e-Skyactiv-X and the range-topping Takumi and GT Sport Tech variants climb to group 20–21. That's a much tighter spread than the Mazda 6, so trim choice moves the price less dramatically here.
Size and weight. The CX-30 is a compact crossover built on the Mazda 3 platform, not a big body-on-frame 4x4. It's light, the panels aren't expensive, and repair costs stay reasonable — which is exactly why its groups are lower than you might expect for an SUV.
Safety kit. Every CX-30 ships with a deep bundle of driver aids (autonomous emergency braking, blind-spot monitoring, lane-keep), and it scored a full five stars at Euro NCAP. Good crash-avoidance tech helps hold the groups down.
You, and your postcode. As ever, age, location, mileage and no-claims history swing the final figure far more than the badge does. A clean forties driver in a quiet postcode might pay well under £560; a new driver in a city will pay multiples of that.

The numbers

Mazda CX-30 insurance cost by driver age

These indicative annual comprehensive figures use a lower-group CX-30 (a group-12 SE-L petrol) as the reference car. The shape is the familiar one — young drivers pay a heavy premium, the price tumbles through the late twenties, and it settles to its cheapest in the forties and fifties before creeping up a little in retirement.

Under-25s pay the most; premiums settle in the 35–64 band, close to the £600 UK average.

Driver age band	Indicative annual premium	Notes
17–24 (young / new)	£900–£1,600	Highest band — roughly £1,250 on a group-12 petrol; a higher-group e-Skyactiv-X would be more, and a black box helps most here
25–34	£560–£720	Around £640 once a couple of no-claims years are banked; close to the national quoted average
35–64	£500–£620	The cheapest years — roughly £560 for a settled driver with clean history on a low-group trim
65+	£540–£760	Edges up gently with age but stays near the UK average on a modest SE-L

By engine & trim

Which Mazda CX-30 is cheapest to insure?

The CX-30's group spread is narrow, so the difference between the cheapest and dearest trim is smaller than on many rivals — but it still exists, and it follows the engine more than the badge:

2.0 e-Skyactiv-G 122/140ps petrol, SE-L or Sport Lux — groups 12–13. The sweet spot for insurance, and the bulk of used CX-30s on the market.
2.5 e-Skyactiv-G 140ps petrol, Takumi — groups 16–17. A step up, but still comfortably mid-scale.
2.0 e-Skyactiv-X 180/186ps mild hybrid, GT Sport / Takumi — groups 18–21. The clever compression-ignition petrol is the most expensive to insure, partly for its power and partly because it's a pricier engine to repair.

There's no diesel and no plug-in to worry about — Mazda never sold either in the UK CX-30 — so the decision is simpler than it is on, say, the Mazda 6. If insurance is a priority, the plain 2.0 e-Skyactiv-G SE-L is both the cheapest to cover and, frankly, the one most buyers are happiest with. It's worth checking the exact group for your registration against our insurance groups guide, since the e-Skyactiv-X cars can be two trims apart yet four groups higher.

Save money

How to cut the cost of Mazda CX-30 insurance

The CX-30 is already one of the cheaper compact SUVs to insure, but the usual levers still shave real money off.

Stick to the 2.0 e-Skyactiv-G petrol. Groups 12–13 versus up to 21 for the e-Skyactiv-X means the entry engine is the cheapest to insure as well as to buy.
Build and protect no-claims. Each clean year chips away at the premium; protecting a long no-claims record is usually worth the small extra cost.
Raise your voluntary excess to a level you could actually cover after a claim — it lowers the premium without changing anything else.
Pay annually, not monthly. Instalment APRs of 20–30% mean monthly billing typically adds £60–£90 a year on a car like this.
Keep mileage honest and park securely. A realistic lower annual mileage and a driveway or garage both pull the price down a little.
Compare the whole market at renewal. Auto-renewal is where owners quietly overpay; ten minutes on a comparison run almost always beats last year's price.

FAQs

Mazda CX-30 insurance: your questions answered

What insurance group is the Mazda CX-30 in?

The Mazda CX-30 (2019-on) spans insurance groups 12 to 21 out of 50. The 2.0 e-Skyactiv-G petrol in SE-L and Sport Lux trim sits at the bottom (groups 12–13), the 2.5 Takumi lands around groups 16–17, and the 2.0 e-Skyactiv-X mild hybrid in GT Sport or Takumi spec reaches group 20–21. That's a tight spread for an SUV, so check the group for your exact engine and trim. See our insurance groups guide for how the scale works.

How much does Mazda CX-30 insurance cost a year?

Around £760 a year on our composite for fully comprehensive cover, or roughly £68 a month. Finder doesn't publish a standalone CX-30 figure, so we benchmark to the closely related Mazda CX-3 (£770) and adjust down slightly because the CX-30 sits in lower insurance groups. That puts it a little above the £600-ish UK all-cars average. Your own quote depends heavily on age, postcode, trim and no-claims history.

Is the CX-30 cheaper to insure than the Mazda CX-5?

Usually, yes. The CX-30 starts in group 12, whereas the larger CX-5 starts around group 15 and runs to 23, so on like-for-like profiles the CX-30 tends to come in a little cheaper. It's the smaller, lighter car with lower repair costs. If you want the extra space the CX-5 offers you'll pay a modest insurance premium for it; if you don't need it, the CX-30 is the thriftier choice. See our Mazda CX-5 insurance cost page to compare directly.

Which CX-30 engine and trim is cheapest to insure?

The 2.0 e-Skyactiv-G petrol in SE-L or Sport Lux trim, which falls in insurance groups 12–13. Avoid the 2.0 e-Skyactiv-X mild hybrid in GT Sport or Takumi spec if premium is your priority — those reach group 20–21 and cost more to cover. There's no diesel or plug-in CX-30, so the entry petrol is the clear budget pick and the one most owners are happiest with anyway.

Is the Mazda CX-30 a good first car for insurance?

It's better than most SUVs, but still not a cheap first car. A group-12 petrol CX-30 is quoted around £1,250 for a 20-year-old on our composite — less than many crossovers, but more than a group-1 city car. If a new driver has their heart set on a CX-30, the 2.0 e-Skyactiv-G SE-L plus a black box and modest mileage is the sensible combination. A smaller car would still start out cheaper to insure.

Does the mild-hybrid or e-Skyactiv-X engine affect insurance?

Every CX-30 petrol is a mild hybrid, which is a small 24-volt system rather than a full hybrid or EV, so it doesn't drag the car into high-cost electrified-repair territory. The e-Skyactiv-X engine does cost more to insure — but that's down to its higher power and pricier engineering, which place it in groups 18–21, rather than the mild-hybrid part itself. The ordinary e-Skyactiv-G stays in groups 12–13.

Do modifications increase CX-30 insurance?

Yes. Performance, cosmetic or wheel modifications generally raise the premium and must always be declared — leaving one off can void a claim or the policy. A standard, unmodified CX-30 is always the cheapest to insure. If you buy one with mods already fitted, tell the insurer precisely what's on the car before you take out cover.

Will a black box policy make a CX-30 cheaper?

For younger and newer drivers, usually yes. A telematics policy prices you on how you actually drive rather than on age alone, which can meaningfully cut a 17–24 premium even on a compact SUV like the CX-30. For settled 35–64 drivers with several years of no-claims the saving is smaller, and often not worth the curfews and mileage limits a box brings.
