If you’re buying a Porsche 911 for the first time one of the first questions you’ll ask your insurer is — what insurance group is it in? The answer will have a significant impact on what you pay every year. Understanding how insurance groups work and which 911 variants sit in which groups could save you thousands of pounds over the lifetime of your ownership.
This is our complete guide to Porsche 911 insurance groups — what they mean, which models are affected, and how to reduce your premium despite being in a high group.
What Are Insurance Groups and How Do They Work?
Every car sold in the UK is assigned an insurance group by Thatcham Research — the automotive safety and security research organisation. Insurance groups run from 1 to 50 — with group 1 being the cheapest to insure and group 50 the most expensive.
The group a car sits in is determined by a range of factors including:
Performance and engine power More powerful cars are statistically more likely to be involved in accidents and more likely to cause serious damage when they are. Higher power = higher group.
Repair costs How expensive is the car to repair after an accident? Parts availability, labour rates, and the complexity of repairs all feed into the group rating. Porsche parts are expensive and specialist labour rates are high — this pushes groups up.
New car value More expensive cars cost more to replace or repair after a total loss. The 911’s high purchase price contributes to its group rating.
Security Cars with better security features — immobilisers, alarms, tracking devices — are rated more favourably. Modern 911s have excellent factory security which helps.
Safety rating Euro NCAP safety ratings and the quality of safety systems influence the group. Modern 911s score well here.
Parts price index Thatcham benchmarks the cost of 23 common replacement parts. For a Porsche — where even minor parts carry premium pricing — this pushes the group rating higher.
What Insurance Group Is a Porsche 911?
The Porsche 911 sits in the highest insurance groups across all variants — typically between group 40 and group 50 depending on the specific model, generation, and specification.
Here’s a breakdown by generation and variant:
996 Generation (1997–2005):
- 996 Carrera: Group 42–44
- 996 Carrera S: Group 44–46
- 996 Turbo: Group 48–50
- 996 GT3: Group 49–50
997 Generation (2004–2012):
- 997 Carrera: Group 43–45
- 997 Carrera S: Group 45–47
- 997 Turbo: Group 49–50
- 997 Turbo S: Group 50
- 997 GT3: Group 49–50
991 Generation (2011–2019):
- 991 Carrera: Group 44–46
- 991 Carrera S: Group 46–48
- 991 Turbo: Group 49–50
- 991 Turbo S: Group 50
- 991 GT3: Group 50
992 Generation (2019–present):
- 992 Carrera: Group 45–47
- 992 Carrera S: Group 47–49
- 992 Turbo S: Group 50
- 992 GT3: Group 50
As you can see the standard Carrera models sit slightly lower than the Turbo and GT variants — but all 911s are firmly in the upper tier of insurance groups. There is no such thing as a cheap-to-insure 911.
Why Are Porsches in Such High Insurance Groups?
The 911’s high insurance group rating comes down to four main factors:
Performance Even the base 997 Carrera produces over 320bhp and reaches 62mph in under 5 seconds. The 991.2 Turbo S produces 580bhp and hits 62mph in 2.9 seconds. These are genuinely fast cars and insurers price that risk accordingly.
Parts cost Porsche genuine parts are expensive. A replacement bumper, bonnet, or door panel for a 911 costs significantly more than equivalent parts for a mainstream car. Even consumables like brake discs and pads carry a premium. Thatcham’s parts price benchmark pushes every 911 into a high group.
Specialist labour Porsche 911s require specialist knowledge to repair correctly. Bodyshops and mechanics who can work on these cars charge premium rates — and insurers factor this into their group assessment.
Vehicle value A used 997 Carrera S costs £35,000–£55,000. A 991.2 Turbo S can cost £120,000+. The higher the vehicle value the higher the potential payout for the insurer — and the higher the group rating.
How Do Insurance Groups Affect Your Premium?
Insurance groups are one of many factors that determine your premium — but they’re an important one. Here’s how the group rating feeds into your actual cost:
The group sets a baseline A car in group 50 will always cost more to insure than an identical car in group 40 — all other factors being equal. The group is a starting point that insurers adjust based on your personal profile.
Your personal profile matters enormously Your age, driving history, occupation, annual mileage, where the car is kept overnight, and your no claims bonus all have a significant impact on your final premium — often more than the insurance group itself.
Example premiums for a 997 Carrera S (group 46):
- Driver aged 25, clean licence, 5,000 miles per year, garaged: £1,800–£2,500
- Driver aged 35, clean licence, 7,000 miles per year, garaged: £1,200–£1,800
- Driver aged 45, clean licence, 5,000 miles per year, garaged: £900–£1,400
- Driver aged 55+, clean licence, 5,000 miles per year, garaged: £700–£1,100
Example premiums for a 997 Turbo (group 50):
- Driver aged 35, clean licence, 7,000 miles per year, garaged: £2,000–£3,000
- Driver aged 45, clean licence, 5,000 miles per year, garaged: £1,500–£2,200
- Driver aged 55+, clean licence, 5,000 miles per year, garaged: £1,000–£1,600
The jump from group 46 to group 50 typically adds £400–£800 per year to your premium — significant but not prohibitive given the performance difference between the two cars.
Which 911 Variants Are Cheapest to Insure?
If insurance cost is a significant factor in your buying decision here’s where to focus:
Cheapest 911 to insure — 996 Carrera The 996 Carrera sits in group 42–44 — the lowest of any 911 variant. Its lower value compared to newer generations means insurers face a lower potential payout. A well maintained 996 Carrera with full history can be insured for £800–£1,500 per year for a mature driver with a clean licence.
Best value balance — 997.1 Carrera The 997.1 Carrera in group 43–45 offers the classic 997 styling and driving experience at a lower insurance cost than the Carrera S or Turbo variants. For buyers who want a 997 on a tighter insurance budget this is the sweet spot.
Most expensive to insure — 991.2 Turbo S, 992 GT3, any GT variant Any car in group 50 will carry the highest possible premium. GT3, GT3 RS, and Turbo S variants attract the most expensive insurance across all generations. If you’re buying one of these be prepared for insurance costs that can exceed £5,000 per year for younger drivers.
Tips to Reduce Your Premium Despite a high Porsche 911 insurance groups
Being in group 46-50 doesn’t mean you’re stuck with a huge premium. Here are the most effective ways to reduce your costs:
Use a specialist insurer This is the single most important step. Specialist performance car insurers — Hagerty, Adrian Flux, Footman James — understand these cars and their owners far better than mainstream insurers. They consistently offer better premiums than comparison sites for high group cars.
Agreed value policy An agreed value policy doesn’t directly reduce your premium but ensures you’re properly covered. Some specialist insurers offer better rates for agreed value policies because they attract more responsible, enthusiast owners.
Garage your car Keeping your 911 in a locked garage overnight can reduce your premium by 15–25%. If you don’t currently have a garage it’s worth considering.
Limited mileage policy If your 911 is a second car or weekend vehicle declaring a realistic lower annual mileage reduces your premium meaningfully. Many specialist insurers offer mileage-based policies specifically for enthusiast cars.
Fit a Thatcham approved tracker A GPS tracker approved by Thatcham Research reduces theft risk and many insurers discount premiums for tracked cars. Popular options include Tracker Network and Meta Trak. Supply and fitting costs £200–£400 plus an annual subscription.
Join Porsche Club GB Porsche Club GB membership at £85 per year gives access to the club’s own insurance scheme with preferential rates. For many owners the insurance saving alone covers the membership fee. Read our full guide to Porsche Club GB membership for more details.
Build your no claims bonus Protect your no claims bonus at all costs. A maximum no claims bonus can reduce your premium by 60–75% — the most powerful premium reduction available to any driver.
Increase voluntary excess Increasing your voluntary excess reduces your premium but means a higher out of pocket cost if you claim. Only do this if your excess remains comfortably affordable.
Consider telematics Some specialist insurers now offer telematics policies for performance car owners. If you’re a younger driver a telematics policy that demonstrates responsible driving can unlock significantly better rates over time.
Final Thoughts
Every Porsche 911 sits in a high insurance group — that’s simply the reality of owning one of the world’s great performance cars. But high group doesn’t have to mean unaffordable premium.
Use a specialist insurer, garage your car, join Porsche Club GB, protect your no claims bonus, and fit a tracker — do all of those things and you’ll be paying a premium that genuinely reflects the pleasure of owning a 911.
The insurance cost is part of the ownership experience. Factor it into your budget, manage it sensibly, and don’t let it put you off the car you really want.
