Mazda 3 Insurance Cost UK (2026)

Direct answer

What does it cost to insure a Mazda 3?

The typical fully comprehensive premium for a Mazda 3 in the UK is about £783 per year, or roughly £70 a month when paid monthly, according to Finder. That is modestly above the UK average of around £600 (see our cost index), and sits between the £560 all-driver average reported by the ABI for Q1 2026 and the £711 market average recorded by the Confused.com Price Index over the same period. Real quotes span a wide band — from under £330 to well over £2,900 — depending on your age, postcode, trim and no-claims history.

Four things drive the Mazda 3's insurance cost:

Insurance group. The current (2019-on) Mazda 3 hatchback falls in groups 15 to 24 of the 1–50 scale, per Parkers. Entry SE-L and Prime-Line trims with the 2.0 e-Skyactiv G mild-hybrid sit at the cheap end (groups 15–16); the 186ps e-Skyactiv X Takumi tops out at group 24. Across all generations the badge has ranged from group 9 up to group 34 for the old MPS 2.3 turbo, so always check the exact variant.
Value and repair cost. The Mazda 3 is a mainstream family hatchback with widely available parts, so repairs after a knock are reasonable rather than premium-brand expensive — which keeps groups in the mid-range rather than high.
Security. Alarm, immobiliser and Mazda's standard security package help hold groups down; the car is not a high-theft target relative to hot hatches.
Performance. Sensible power outputs (mostly 122–186ps) mean insurers see the Mazda 3 as low-to-moderate risk, unlike turbocharged rivals that jump several groups.

The numbers

Mazda 3 insurance cost by driver age

These indicative annual comprehensive figures use a lower-group Mazda 3 as the reference car and show how sharply age moves the premium. Younger drivers pay a large multiple of the settled-driver rate; costs level off from the mid-30s onward.

Driver age band	Indicative annual premium	Notes
17–24 (young / new)	£900–£1,700	Highest band; a 20-year-old is quoted around £917 on a low-group car, rising steeply for 17–18s
25–34	£500–£650	Around £511 for a 30-year-old; near the UK average once no-claims builds
35–64	£480–£600	Cheapest years; roughly £500 for a 40-year-old with clean history
65+	£500–£700	Creeps up slightly with age but stays close to the national average

Indicative figures. Age-band anchors derived from Finder sample quotes (20yo £916.69, 30yo £511.43, 40yo £500.06, 50yo £493.38) and young-driver averages from the ABI and Confused.com Q1 2026. Your own quote will vary by postcode, trim, mileage and claims history.

Cheapest way to insure a Mazda 3

Pick a lower-group trim. A 2.0 e-Skyactiv G SE-L or Prime-Line (groups 15–16) is materially cheaper to insure than a Skyactiv X Takumi (group 24). If insurance cost matters, buy at the bottom of the range.
Build and protect no-claims. Every year of no-claims discount cuts the premium; protecting it once you have five-plus years is usually worth it.
Increase your voluntary excess to a level you could actually afford to pay after a claim — it lowers the premium.
Add an experienced named driver (never a fronting arrangement) to reduce a younger main driver's risk profile.
Pay annually, not monthly. Monthly instalments carry interest — on a Mazda 3 that gap is roughly £60–£80 a year.
Reduce mileage and improve security — a realistic lower annual mileage and a garage or off-street parking both help.
Compare widely and switch at renewal. Loyalty rarely pays; the cheapest Mazda 3 quotes come from shopping around, and prices in 2026 have been falling year-on-year.
Consider telematics if you are young — a black box can meaningfully cut a 17–24 premium on a modest-group car like the Mazda 3.

FAQs

Mazda 3 insurance: your questions answered

What insurance group is the Mazda 3 in?

The current 2019-on Mazda 3 hatchback sits in insurance groups 15 to 24 out of 50. Entry 2.0 e-Skyactiv G mild-hybrid trims (SE-L, Prime-Line) are groups 15–16, while the 186ps e-Skyactiv X Takumi reaches group 24. Older Mazda 3s have ranged from group 9 to group 34 (the discontinued MPS 2.3 turbo), so check your exact registration and trim. See our insurance groups guide for how the scale works.

Why does a Mazda 3 cost what it does to insure?

Its group placement reflects a mainstream family hatchback with moderate power, reasonable repair costs, good standard security and a low theft profile. That keeps it in the middle of the insurance scale — more than a city car, far less than a hot hatch. The typical £783 comprehensive premium is only modestly above the UK average.

Which Mazda 3 trim is cheapest to insure?

The 2.0 e-Skyactiv G mild-hybrid in SE-L or Prime-Line trim, which falls in insurance groups 15–16. Avoid the higher-powered Skyactiv X 186ps variants and top Takumi spec if you want the lowest premium — they climb toward group 24.

Which insurer is cheapest for a Mazda 3?

There is no single cheapest insurer — it depends on your age, postcode and history. The reliable approach is to compare the whole market at renewal rather than auto-renewing. Quotes for the same Mazda 3 have been shown to range from under £330 to over £2,900, so shopping around is where the real saving is.

Is the Mazda 3 cheap to insure for new or young drivers?

It is reasonable rather than cheap for young drivers. A low-group Mazda 3 might cost a 20-year-old around £917, and 17–18-year-olds considerably more — the 17–24 UK average is roughly £1,100 across all cars. A group-15 trim plus a black box gives new drivers the best shot at an affordable Mazda 3 premium.

Is the Mazda 3 a hybrid, and does that affect insurance?

Current Mazda 3 petrol engines are mild hybrids (e-Skyactiv G and e-Skyactiv X), not full hybrids or EVs — there is no plug-in or battery-electric Mazda 3. The mild-hybrid system is modest and does not push the car into high-cost EV repair territory, so it has little adverse effect on group or premium; the lower-powered mild-hybrid trims are actually the cheapest to insure.

Do modifications increase Mazda 3 insurance?

Yes. Performance, cosmetic or wheel modifications typically raise the premium and must always be declared — failing to disclose them can void a claim. A standard, unmodified Mazda 3 will always be the cheapest to insure.

Will a black box (telematics) policy make a Mazda 3 cheaper?

For younger and newer drivers, usually yes. A telematics policy prices you on how you actually drive rather than age alone, which can meaningfully reduce a 17–24 premium on a modest-group car like the Mazda 3. For settled 35–64 drivers with strong no-claims, the saving is smaller.
