A 991 Porsche 911 sits in Thatcham insurance group 49 or 50 on most variants, and the 992 sits at 50 across the board.

How CDE compared the two insurers for a 991 or 992 owner

Walked each insurer’s published Porsche page and policy summary on 25 May 2026; cross-referenced the FCA Financial Services Register for current authorisation; searched Financial Ombudsman Service published guidance on motor valuations and agreed-value disputes; and read recent RennList UK and PistonHeads Porsche-insurance threads. We did not source quotes (premiums depend on postcode, age, no-claims and mileage). We compared policy structure: agreed-value mechanism, mileage tiers, modifications, track-day stance and claims pay-out.

Hagerty UK: FCA firm reference 441417, currently authorised.
Adrian Flux: FCA firm reference 307071, currently authorised (broker model).
FOS context: agreed-value policies are uncommon and reserved for classic and valuable cars; the insurer must pay the agreed amount on total loss.

Why specialist Porsche insurance exists (and why mainstream insurers either decline or surcharge)

A 991 Porsche 911 sits in Thatcham insurance group 49 or 50 on most variants, and the 992 sits at 50 across the board. Mainstream comparison-site panels (Direct Line, Aviva, Admiral) are built for groups 1 to 40, and their pricing engines treat anything in the high 40s as either a decline or a substantial uplift. The reasons are mechanical: a rear-engined sports car with 380-650 bhp and a known parts-cost premium does not fit a volume motor book.

Specialist insurers bridge that gap. They underwrite a 911 because they understand the car, accept the parts cost on a claim and price the policy on how the car is actually used. The two names a 991 or 992 owner will meet first are Hagerty UK and Adrian Flux. Both are FCA-authorised, both will quote on a 911, and both publish their policy structures openly. The question is which one fits which owner profile.

Hagerty UK: who they are, what they cover, agreed value mechanics

Hagerty is a global classic and enthusiast insurer that opened a UK operation under Hagerty International Limited. The UK arm is authorised by the Financial Conduct Authority at firm reference number 441417, which you can verify on the FCA Financial Services Register before buying. Hagerty runs an underwriting capability rather than only acting as a broker.

The product is built around agreed value rather than market value. When you take out the policy, you and Hagerty agree what the car is worth (using Hagerty’s own valuation database, the same data feeding their Porsche price guide), and that figure goes onto the schedule. If the car is written off, the agreed figure is what the insurer pays out, subject to excess. There is no haggling over a CAP Black Book value at the worst possible moment. For a 991 or 992 where values move in both directions depending on spec and mileage, that mechanism is the point of the policy.

The other Hagerty feature that suits an enthusiast 911 owner is limited mileage. The policy assumes the car is a second or third car, not a primary daily. Modifications are accepted with disclosure at quote, and laid-up cover is available over winter. Track day cover is not part of the standard road policy; Hagerty UK offers a separate Motorsport or on-track policy through a specialist partner. Track time is a separate product, not a road-policy extension.

Adrian Flux: who they are, what they cover, modification and track-day stance

Adrian Flux is a broker, not an underwriter. The business is registered at East Winch Hall in King’s Lynn, Norfolk, and the FCA register lists Adrian Flux Insurance Services Group at firm reference 307071, currently authorised. Flux places business across a panel of more than thirty specialist motor underwriters and shops your risk for the best fit. That panel approach is why two 911 owners with similar specs can end up on quite different underwriters and quite different premiums.

The Porsche 911 page at adrianflux.co.uk lists agreed-value cover and total-loss protection as optional extras at quote, not policy defaults. That is the cleanest difference between the two insurers: at Hagerty the agreed value is baked in; at Flux you opt in and the chosen panel underwriter sets the valuation mechanism. Modifications are accepted as standard, which is one reason Flux is popular with owners who have fitted a sports exhaust, lowered suspension, or aftermarket wheels. Multi-car and named-driver-only options are where the genuine premium savings sit.

Track day cover at Flux follows the industry pattern: the road policy excludes circuit use, and Flux sells a separate annual trackday product covering hill climbs, drag strips and organised circuit events. Modifications fitted for circuit use do not affect the trackday premium, useful if you have a stripped interior or roll cage on a 991 GT3. For a road-only 992 Carrera S that occasionally attends a sprint event, you carry a road policy plus a separate trackday or single-event cover.

Mileage tiers: where the pound-saving sits for a weekend 911

The most useful lever on a specialist 911 policy is annual mileage. The saving between a 3,000-mile and a 10,000-mile policy is typically more than the saving from a few hundred pounds of voluntary excess. The mechanics differ:

Hagerty UK: tiered limited-mileage bands are written into the schedule. If you approach the band, you contact Hagerty and uplift; you do not pay a claims penalty for honest reporting. Owners who use the 911 only on dry weekends rarely exceed 5,000 miles a year and benefit directly.
Adrian Flux: the panel approach means the underwriter sets the mileage rules. Some accept a strict limited-mileage policy similar to Hagerty’s; others offer an “as declared” mileage that prices around your stated figure without a hard cap. Ask which structure your quote sits on.

If you are a 991 or 992 owner doing 12,000 to 15,000 mostly-commute miles a year, you are not the natural Hagerty customer. The agreed-value benefit still applies but the mileage premium erodes the saving. Flux’s broader panel tends to fit this profile better, particularly with named-driver-only configurations.

Claims experience: pay-out speed and how each handles a total loss

Both insurers’ policy summaries describe the same claims process: notify within the stated period, engineer inspection, total loss triggers the schedule valuation, pay-out follows. The Financial Ombudsman Service’s guidance is explicit: where a policy is written on agreed value, the insurer must pay that amount on total loss, not a depreciated market figure. Disputes most often arise when the agreed value has not been updated and the customer expects the current open-market figure instead.

Practical implication for a 911 owner: review the agreed value annually. A 992 Carrera S bought at £100,000 in 2024 may sit at £85,000 in May 2026; a 991.2 GTS may have moved the other way. The schedule needs to reflect today’s market. Both insurers will adjust mid-term if you ask, and the FOS guidance supports the customer who has kept their valuation current.

Which one fits which 911 owner profile

The split is by use case, not by generation. Both insurers will quote a 991 or a 992; the fit depends on how the car lives in your life.

Hagerty UK fits best if: the 911 is your weekend or second car; you do under 5,000 miles a year; you want agreed value as the policy default; the car is broadly standard or has only OEM-quality modifications.
Adrian Flux fits best if: the 911 is closer to a daily driver; you do 8,000 to 15,000 miles a year; you have meaningful modifications and want them priced explicitly; you want named-driver-only or multi-car structures to bring the premium down.
Both, or neither: for serious track time, carry a road policy at one of these insurers plus a separate trackday policy. Do not assume your road cover travels onto the circuit; it does not.

Our take

If you are buying a 991 or 992 today and the car will spend most weekends in the garage, Hagerty UK is the cleaner product. Agreed value baked into the policy, limited-mileage tiers that reward low use, and a single underwriter you can verify at FRN 441417.

If the 911 is closer to your daily, carries meaningful modifications, or you want named-driver-only pricing, Adrian Flux’s broker model usually finds a better number (FRN 307071). Ask which panel underwriter you sit on, what the agreed-value option costs as an extra, and whether the mileage rule is banded or declared.

Neither insurer covers track time on the road policy. If you do trackdays, budget separately at the outset.

FAQ

Is Hagerty UK only for classic cars, or does it cover a modern 992 911?

Hagerty UK covers both classic and modern enthusiast cars. A 992 generation 911 is well inside their underwriting appetite, and the policy structure (agreed value, limited mileage) is the same as for a 991 or an air-cooled 964. The car needs to fit the enthusiast or second-car profile.

Does Adrian Flux cover track day use on a Porsche 911?

Not on the standard road policy. Adrian Flux publishes a separate annual trackday product that covers circuit days, hill climbs, drag strips and organised events; modifications fitted for circuit use do not push up the trackday premium. You carry a road policy and a trackday policy in parallel.

What is agreed-value cover and why does it matter on a 911?

You and the insurer fix the car’s value in writing at inception and at each renewal. On a total loss the insurer pays that figure rather than a market valuation. The Financial Ombudsman Service’s guidance confirms the insurer is obliged to pay the agreed amount. For a 991 or 992 where values can swing fast, that mechanism removes the worst argument you can have with a claims handler.

Can I insure a modified Porsche 911 with Hagerty UK?

Yes, with disclosure at quote. Hagerty UK accepts modifications on enthusiast cars; every modification must be declared up front and recorded on the schedule. Failure to disclose at inception is the most common reason a modified-car claim is reduced or declined at any insurer.

How do I check that my Porsche insurance is FCA-authorised?

Open the FCA Financial Services Register at register.fca.org.uk and search by firm name or FRN. Hagerty International Limited’s FRN is 441417; Adrian Flux Insurance Services Group’s FRN is 307071. Verify before you pay the premium, not after.
