A Quarter of Britain's Car Insurance Is Written Here, on a Rule That Expires in December

28 September 2026 Last checked 2026-09-28

Roughly a quarter of UK motor insurance is underwritten in Gibraltar. No official body publishes the real figure, and the legal basis has been renewed one year at a time since 2020.

Somewhere between one in five and one in three British motor insurance policies is underwritten in Gibraltar. The range is that wide because nobody official counts.

The second thing worth knowing is that the legal arrangement letting them do it runs out at the end of 31 December 2026. It has been extended by twelve months, six times over. The permanent replacement passed into UK law in 2021 and still has not been switched on.

This post does two things. It shows where the market share numbers come from and why they disagree, and it sets out what a Gibraltar underwritten policy actually means for you when something goes wrong. Every claim links to its source.

Nobody publishes the number

Gibraltar Finance, the government's own promotional arm, puts it at over 20% of the UK motor insurance market, crediting the estimate to one of the Big Four accountancy firms that it does not name and does not date. The same page says there are over 25 motor insurers currently writing new business in Gibraltar, and that motor makes up around 75% of the territory's non-life gross premium income.

Estimates elsewhere run higher. Figures of 26%, 30% and more have circulated in the insurance trade press over the last five years. They move around because the people producing them are consultancies sampling the market at different dates on different definitions.

What does not exist, as far as we can find, is an official statistic. The Gibraltar Financial Services Commission does not publish a UK market share. Neither the Financial Conduct Authority nor the Prudential Regulation Authority breaks out UK motor premium by the insurer's domicile in a public series. So the honest sentence is that Gibraltar underwrites roughly a quarter of British motor insurance, that the trend has been upward, and that anyone quoting you a decimal place is guessing.

Treat that as a warning about the rest of the internet on this subject. One in five was a fair estimate around 2018. It is probably low now, and it is still the figure most pages repeat.

The rule expires on 31 December, for the sixth time

Before Brexit, Gibraltar insurers reached the UK through European single market passporting. Afterwards they needed something else, and the something else was designed to be temporary.

Regulation 12(1) of the Financial Services (Gibraltar) (Amendment) (EU Exit) Regulations 2019 said Parts 2 and 3 of those Regulations cease to have effect at the end of 31 December 2020. Regulation 12(2) lets the Treasury extend that, and is unusually specific about how: it may only extend the period by 12 months on each occasion. Regulation 12(3) then requires the Treasury to publish and lay before Parliament a statement describing the progress it has made in preparing the replacement legislation.

It has done exactly that, every year since. The most recent instrument, the Financial Services (Gibraltar) (Amendment) (EU Exit) Regulations 2025, was made on 11 November 2025 and came into force on 16 December 2025. Its entire operative text substitutes 2026 for 2025. Six annual reprieves, each one requiring a progress report on the thing that has not happened yet.

What is supposed to replace it

The permanent regime is the Gibraltar Authorisation Regime, and it is already law. Section 22 of the Financial Services Act 2021, with Schedules 6 and 8, creates it. The design is that HM Treasury designates Approved Activities, meaning UK regulated activities that Gibraltar firms may carry on in the UK, and matching Corresponding Activities in Gibraltar. A firm needs GFSC permission for the Corresponding Activity before it can notify and begin the UK one.

It is not in force. Gibraltar Finance's own page on the regime still says the current estimated timeline is that the regime will come into force in 2024, which tells you roughly how long that page has been waiting for an update. We could not find a published commencement date, and we are not going to invent one.

A quarter of Britain's motor insurance runs on a rule Parliament wrote to last twelve months.

What a Gibraltar policy means for you

Five questions, five answers, each one traceable to the body that decides it.

The tax row is where most of the folklore lives. Gibraltar does not make your premium cheaper by avoiding tax on it. The published HMRC rates apply to the risk, and a car on a British road is a British risk. What the domicile changes is the insurer's own cost base: corporation tax at 15% since 1 July 2024, raised from 12.5%, plus a regulator small enough to answer the phone.

The ombudsman row is the one that surprises people. The FCA's guidance on dealing with firms based in Gibraltar is blunt: ombudsman access is not guaranteed, and compensation cover is not uniform across products. Insurance is better protected than investments or home finance. Better is not the same as identical.

Four Gibraltar insurers have failed on UK policyholders, and one cancelled the policies

None of this is hypothetical. The pattern is roughly one failure every two or three years, and the worst of them shows exactly where compensation stops.

Enterprise Insurance Company plc went into liquidation on 1 July 2016, affecting around 46,000 UK customers holding Enterprise motor policies. On 26 October 2016 the liquidator, Grant Thornton in Gibraltar, cancelled those policies outright. Anyone still driving on one was uninsured from that date, and the FSCS cannot protect a claim for an accident after it. What the scheme did do was pay out over 2 million pounds in return of premium claims in the first two weeks.

Read that twice, because it is the most useful sentence on this page. Compensation for a failed insurer does not mean your cover continues. It can be terminated under insolvency law, and the legal duty to be insured stays with you.

Elite Insurance Company Ltd, also Gibraltar based, entered administration on 11 December 2019 and was declared in default the same day. It is still not finished. In March 2026 the joint administrators secured court permission to convene creditor meetings, held on 7 May 2026, to vote on a scheme of arrangement closing the business, under which protected policyholders could keep claiming until 31 December 2027. Eight years from failure to final cut off.

MCE Insurance Company Limited was declared in default on 19 November 2021. It underwrote motorbike, car, van, courier and fast food delivery cover sold through a UK broker with a very similar name, which is precisely the confusion this structure invites.

Then on 14 October 2025, Premier Insurance Company Limited stopped trading and was declared in default, with over 16,000 individual customers and small firms expected to be protected. Grant Thornton in Gibraltar again handled it, contacting affected customers directly rather than leaving them to file claims.

The FSCS position on insurance is 100% of any compulsory element, which for motor means your third party cover, and 90% of the rest with no upper limit. So the protection is real, and a Gibraltar address on the certificate does not leave you on your own. It is not the same as nothing happening to you.

Why Gibraltar in the first place

The single market did it. The third insurance directives, due to be implemented across the European Union by July 1994, completed the single passport: an insurer authorised in one member state could sell across the rest without a second licence. Gibraltar was inside the EU through the United Kingdom, so its insurers could passport, and it had two things the larger domiciles did not.

The first was speed. A regulator in a territory of 37,936 people turns an application around faster than one supervising thousands of firms, and speed to market is worth real money to a motor start up. The same structural advantage runs through the crypto licensing framework we wrote about, for the same reason.

The second was tax. Gibraltar's standard corporation tax was 10% until August 2021, then 12.5%, and has been 15% since 1 July 2024. All three sit under the UK main rate. That is not a scandal. It is the business model, and it is published on the government's own tax pages rather than hidden.

What Brexit did was remove the original point of the arrangement, the European passport, while leaving the British book exactly where it was. Gibraltar's insurers kept the customers and lost the legal basis, which is why the UK has spent six years renewing a temporary fix rather than turning on a permanent one.

What to do with this if you drive in Britain

Find the underwriter on your certificate, not the brand on the advert. The broker you bought from and the insurer carrying the risk are very often different companies in different jurisdictions, and only one of them pays your claim.

If the underwriter is Gibraltar based, that is not a reason to cancel anything. It is a reason to know three things: your compulsory third party cover is protected in full if the insurer fails, your ombudsman access may not be, and the legal arrangement underneath the policy is renewed one year at a time.

If you are on the other side of it, running or advising an insurer here, the December date is a diary entry rather than an emergency. The Treasury has extended every year and must report to Parliament on the replacement each time it does. Plan for a seventh extension and treat the permanent regime as a bonus.

Where to stay when the business is here

Insurance is an office industry and the offices are on the Rock. Board meetings, GFSC appointments, due diligence weeks and audit visits all mean flying people into a territory where the entire financial district is a ten minute walk end to end. Our guide to business stays in Gibraltar covers the practical side, and temporary accommodation while relocating covers the longer version.

Victory Suites runs 100+ apartments in Gibraltar on Devils Tower Road, on the isthmus, about ten minutes' walk from the frontier. Rates are in GBP and the apartments are listed across 300+ booking channels. For a week of meetings a room does the job. For an audit, a licensing project or an integration after an acquisition, ask us about a longer stay rather than booking night by night.
