Mazda 6 Insurance Cost UK (2026)

A Mazda 6 costs around £848 a year to insure comprehensively in 2026, sitting in insurance groups 16–32 — a fair bit above the UK average, because the 6 is a large, fairly powerful executive saloon and estate rather than a small hatchback. Pick the right engine and trim, though, and you can keep it close to mainstream money.

Direct answer

What does it cost to insure a Mazda 6?

The typical fully comprehensive premium for a Mazda 6 in the UK is about £848 a year, or roughly £76 a month if you pay monthly, according to Finder. That's noticeably higher than the roughly £600 all-cars figure on our UK cost index, and above both the £566 average premium actually paid reported by the ABI for Q2 2026 and the £719 average quoted premium from the Confused.com Price Index over the same window. The gap isn't a surprise. The 6 is a big car — a proper D-segment saloon and Tourer estate with engines up to 194ps — so it naturally costs more to cover than a Mazda 2 or 3.

What the £848 headline hides is how wide the real spread is. Finder found genuine quotes for the same car running from £386 to £5,297, which tells you almost everything about how much your own circumstances matter. Four things move the number most:

Insurance group. The Mazda 6 spans groups 16 to 32 of the 1–50 scale. The 2.0 and 2.5 SkyActiv-G petrol saloons in SE-L and SE-L Nav+ trim sit at the bottom (groups 16–19); the 2.2 diesel and the higher-output 194ps petrol in Sport and GT Sport trim climb toward the low 30s. That 16-group spread is a bigger swing than most families see, so the exact variant on the V5C really does decide the price.
Size and repair cost. A larger body, bigger panels and more safety tech (adaptive cruise, lane keep, a 360-degree camera on higher trims) mean a front-end knock costs more to put right than it would on a supermini. Insurers price that in.
Performance and fuel. The diesels and the 194ps petrol have the performance and the higher replacement value that nudge groups up; the 145ps petrol is the insurer-friendly choice.
Who's driving, and where. Age, postcode, annual mileage and no-claims history routinely matter more than the badge — which is exactly why one driver pays under £400 and another over £5,000 for the identical car.

The numbers

Mazda 6 insurance cost by driver age

These indicative annual comprehensive figures use a lower-group Mazda 6 (a group-16 SE-L estate) as the reference car, so they show the friendliest end of the range. Age moves the premium hard: a driver in their twenties pays roughly double what a settled forties driver pays, and the curve only really flattens from the mid-thirties on.

Under-25s pay the most by a distance; premiums settle from the mid-30s, a little above the £600 UK average.

Driver age band	Indicative annual premium	Notes
17–24 (young / new)	£1,100–£1,900	Highest band by far — a 20-year-old is quoted around £1,482 even on a low-group 6; a group-30 diesel would be well over £2,000
25–34	£700–£950	Around £849 for a 30-year-old; the premium drops quickly once a couple of no-claims years are on record
35–64	£600–£720	The cheapest years — roughly £660 for a 40-year-old with clean history, close to the national average
65+	£640–£820	Creeps up gently with age but stays within reach of the UK average on a modest trim

By engine & trim

Which Mazda 6 is cheapest to insure?

Because the 6 spans sixteen insurance groups, engine and trim choice is the single biggest lever you control before you've even had a quote. The pattern is consistent across the 2013–2023 range (the last generation sold new in the UK):

2.0 SkyActiv-G 145ps petrol, SE-L or SE-L Nav+ — groups 16–19. This is the bargain of the range and the one to aim for if insurance cost is front of mind.
2.5 SkyActiv-G 194ps petrol, Sport Nav+ / GT Sport — mid-to-high 20s. More power and more kit, a clear step up in premium.
2.2 SkyActiv-D diesel (150ps / 184ps), Sport and GT Sport — the top of the range, reaching group 32. The higher replacement value and repair complexity push these well above the petrols.

We see this a lot with big Mazdas: people fall for a loaded GT Sport diesel Tourer, then find the insurance costs £200–£400 a year more than the 2.0 petrol they test-drove first. If you do fewer than about 12,000 miles a year, the diesel's fuel saving rarely covers that gap. The petrol SE-L is usually the smarter total-cost buy. Check the exact group for your registration against our insurance groups guide before you commit — a single trim level can be the difference between group 19 and group 26.

Save money

How to cut the cost of Mazda 6 insurance

None of these are gimmicks, and none of them bend the rules. They're the levers that actually shift a large-saloon premium.

Buy the lower-group engine. A 2.0 petrol SE-L (group 16–19) is materially cheaper to insure than a 2.2 diesel GT Sport (group 32). If you're choosing between two 6s, the group number is worth real money every year you own it.
Build and protect your no-claims discount. On a group-16-plus car the NCD matters more than on a city car; five protected years can knock hundreds off.
Raise your voluntary excess to a figure you could genuinely find after a claim. It lowers the premium, but only take the saving if the excess is one you could actually pay.
Pay annually rather than monthly. Monthly instalments carry interest — often an APR of 20–30% — so on a Mazda 6 that's roughly £70–£100 a year you're handing over for the convenience.
Keep mileage realistic and park it securely. An honest lower annual mileage and a garage or driveway both pull the price down.
Shop the whole market at renewal. Loyalty almost never pays. Given that genuine Mazda 6 quotes span £386 to £5,297, the single biggest saving most owners leave on the table is simply not comparing.

FAQs

Mazda 6 insurance: your questions answered

What insurance group is the Mazda 6 in?

The last-generation (2013–2023) Mazda 6 spans insurance groups 16 to 32 out of 50. The 2.0 SkyActiv-G 145ps petrol in SE-L and SE-L Nav+ trim sits at the bottom (groups 16–19), while the 2.2 SkyActiv-D diesel and 194ps petrol in Sport and GT Sport trim reach the low 30s. That's a wide spread, so check the group for your exact engine and trim rather than the badge. See our insurance groups guide for how the scale works.

How much does it cost to insure a Mazda 6 per year?

About £848 a year on average for fully comprehensive cover, or roughly £76 a month, per Finder UK. That's above the £600-ish UK all-cars figure because the 6 is a large, fairly powerful car. Real quotes stretch from under £400 to over £5,000 depending on your age, postcode, engine and no-claims history, so the average is only a starting point.

Why is a Mazda 6 more expensive to insure than a Mazda 3?

Size, power and replacement cost. The 3 is a family hatchback in groups 13–25; the 6 is a bigger executive saloon and estate with larger panels, more driver-assist tech to repair and engines up to 194ps, so it runs from group 16 to 32. On like-for-like driver profiles the 6 typically costs £60–£120 a year more than a 3, and far more if you pick a diesel GT Sport over a petrol SE-L.

Which Mazda 6 engine and trim is cheapest to insure?

The 2.0 SkyActiv-G 145ps petrol in SE-L or SE-L Nav+ trim, which falls in insurance groups 16–19. Avoid the 2.2 diesel and the 194ps petrol in Sport or GT Sport spec if premium is your priority — those climb toward group 32 and cost noticeably more to cover. The petrol SE-L is usually the smarter total-cost choice unless you do very high mileage.

Is the Mazda 6 expensive to insure for young drivers?

Yes — it's not an ideal first car. Even on a low-group petrol 6, a 20-year-old is quoted around £1,482, and a higher-group diesel can push a young driver well past £2,000. A large executive saloon carries more risk in insurers' eyes than a city car. A new driver set on a 6 should stick to the 2.0 petrol SE-L, add a black box and keep mileage modest; even then, a smaller car would be cheaper to start out on.

Is the diesel Mazda 6 more expensive to insure than the petrol?

Generally yes. The 2.2 SkyActiv-D diesels sit in higher insurance groups than the 2.0 petrols — up to group 32 versus 16–19 — because of their higher value and repair cost, so they cost more to insure. Unless you cover high annual mileage, the diesel's fuel economy rarely offsets the extra insurance and servicing, which is why the petrol SE-L is the cheaper car to run overall for most owners.

Do modifications increase Mazda 6 insurance?

Yes. Performance, cosmetic or wheel modifications usually raise the premium and must always be declared — failing to disclose one can void a claim or even the whole policy. A standard, unmodified 6 is always the cheapest to insure. If you've bought a car with existing mods, tell the insurer exactly what's fitted before you buy cover.

Will a black box policy make a Mazda 6 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 cut a 17–24 premium even on a larger car like the 6. For settled 35–64 drivers with several years of no-claims, the saving is smaller and often not worth the curfews and mileage limits that come with a box.
