UK insurance broking: 30% margins in the shops, nine-figure losses at the top

About 453 UK insurance-distribution companies publish a full profit-and-loss — brokers, agencies, price-comparison sites and the claims and pensions layer around them — booking £10.9bn of combined revenue. The numbers say one thing loudly: this is one of the best service trades in Britain to operate and one of the most expensive to own. A well-run mid-market broker keeps 30p or more of every pound it books — Avantia, the HomeProtect specialist, made £15.8M pre-tax on £47.0M of revenue — and that arithmetic is precisely why private equity spent the last decade buying brokers. But the consolidation vehicles themselves sit deep in the red: PIB Group, the biggest roll-up inside this map, lost £47.8M on £530M of revenue, and the two giants of the buyout era just outside it — Howden’s group holding company and Ardonagh’s — show pre-tax losses of £569M and £473M respectively. The margin is made in the shops and mortgaged at the top. Figures are approximate — verify against a company’s own accounts before relying on any single number.

What this map covers — and what it deliberately doesn’t

Two caveats change how you read everything below.

First, this is the distribution layer, not the insurers. Underwriters — the companies that actually carry the risk — are out of scope. We also stripped 54 lookalikes that carry the industry’s label but aren’t distribution businesses: mis-filed insurers, Lloyd’s corporate-capital vehicles, financing SPVs, and insurance groups’ in-house service companies (the largest was a £42bn shipping group’s holding company). They’re listed at the end; every table and chart here is the genuine-operator basis.

Second, what you see is not the whole market. Several household names hold their UK revenue in entities classified elsewhere — Willis, Lockton, Miller and most of the Howden and Ardonagh empires sit outside this map. Where a company appears in this map, its figures are here; where the story needs one of the others (chiefly the consolidators’ group accounts), we bring it in as labelled context.

One more discipline: margin is not comparable across models. A broker books its commission as revenue; an MGA adds profit commission that can swing wildly year to year; a claims administrator earns flat fees; and none of them book the premium they handle as turnover. Comparing a broker’s 30% to a claims firm’s 5% tells you about the model, not the management.

The giants

The top of the map splits into three species: the UK arms of the global brokers, the vertically-integrated personal-lines machines, and one private-equity consolidator — the only loss-maker in the table.

*A word on the profit column: these are entity accounts, and a group entity’s P&L reflects how revenue and costs are allocated within the group — Aon UK’s £516M is best read that way, not as a 41% operating margin on broking. Marsh’s 5% at the UK entity is the same effect in the other direction.

The cleanest reads are the vertically-integrated distributors: Hastings grew revenue +13% while hiring +18% — genuine expansion — and the brand-and-panel businesses print money at scale: AA Insurance Services at a ~39% margin, GoCompare at ~36% and growing +28%, Simply Business at ~25%. And then there is PIB — 4,000 staff, revenue up +14%, and a £47.8M pre-tax loss. That contrast is the report’s whole thesis, so it deserves its own section.

The roll-up decade: profitable shops, loss-making buyers

Broking consolidates for a simple reason: commission income is sticky, clients renew, and every acquired book adds revenue at high incremental margin. About one in ten companies on this map carries a Holdings/Group/Bidco-style name — the structural fingerprint of a buyout. The roll-ups mid-flight show up clearly in the numbers: Clear Insurance Management grew +53% with headcount +51% (acquisition-led, but real people arriving with real books), Jensten +49% at a 35% margin, Partners& +24% at 19%.

The finished article is less pretty. PIB Group has assembled £530M of revenue and still runs a £47.8M pre-tax loss. Outside this map, the pattern repeats at greater scale: Howden’s group holding company shows a £569M pre-tax loss on £2.9bn of revenue, and Ardonagh’s a £473M loss on £1.5bn — while the broking businesses inside those groups stay comfortably profitable (Howden UK Brokers +£14.6M, A-Plan +£38.8M, Ardonagh Specialty +£29.4M). The gap is the cost of the consolidation itself: debt interest and the amortisation of the goodwill paid for all those 30%-margin shops. None of this means the strategy fails — the bet is on the exit multiple, not the P&L — but it does mean the industry’s headline losses live at the holding-company level while its operating economics remain excellent.

The shape of the market

The mid-market is where the trade is healthiest: the £25–100M band is 93% profitable, the strongest of any band, and even the £1–5M tier runs 82%. The graveyard is the smallest tier — appointed representatives, dormant books and start-ups too small to report a revenue figure — where only half make money.

The quiet compounders

The median margin across the map is about 13%, but the best mid-market operators run at two and three times that — and the pattern in who they are is unmistakable: specialists with a niche book. Avantia (HomeProtect non-standard home cover, 34% — and growing +23% with staff +27%), Alan Boswell (East Anglian broker, 33%), Romero (Leeds commercial broker, ~40%), Caravan Guard (caravans and motorhomes, 38%), and in the London market JB Drax Honoré (specialty and reinsurance, 30% with only 100 staff). The highest margin in the table belongs to One Call (Doncaster personal lines, 38%) — though its revenue fell 9% in the same year, and the firm and its majority owner were fined by the FCA over historic client-money failings, so read that line as margin arithmetic rather than a model to admire.

Not all of these are independents — Tysers Retail sits under an Australian group, Ins-Sure is London-market processing infrastructure rather than a broker — but the underlying point holds: a focused book of clients, personal-lines or specialty, converts to margin that most service industries never see. It is exactly this class of business the consolidators are paying up for.

Growth, read with care

The fastest-growing names are mostly MGAs — managing general agents, who underwrite on insurers’ capital and book commission plus profit commission. That accounting is why their “margins” look implausible: Specialty MGA UK grew +345% with a 74% margin on £37.5M — real momentum, but profit commission and intra-group arrangements can flatter a year enormously; don’t read it as a steady state. Mission Underwriting Services (+472%, staff +525%) is a platform ramping from nothing. The insurtech distributors tell the opposite story: ManyPets +136% at a thin 6%, Marshmallow’s broking arm +49% at 3% — growth bought near cost. The genuine article is growth backed by hiring at a sane margin: Clear (+53% / +51% staff), Avantia (+23% / +27%), Hastings (+13% / +18%), KGM Underwriting (+65% / +23% at a 30% margin).

Market structure

On the genuine-operator basis the top 5 hold 43% of mapped revenue and the top 10 hold 54% — concentrated, but with a deep and healthy mid-market beneath. Treat the curve as a floor on true concentration: Willis, Lockton and the bulk of the Howden and Ardonagh groups sit outside this map, and adding them would steepen the top considerably.

Vintage: an old trade that keeps spawning new firms

For a financial-services industry this is a strikingly young map: the biggest cohorts were founded in the 2000s (101) and 2010–15 (99), and 46 companies from 2021 onwards already publish full accounts — the MGA and insurtech formation wave. Broking has low capital barriers and portable client books, so new firms keep appearing; the pre-1990 cohort (66) is the old guard of regional brokers and mutuals’ managers, many of them the acquisition targets of the roll-up era.

What the map shows

1. Broking is a margin machine. The median operator keeps ~13p in the pound; the best specialist shops keep 30–40p — Avantia, Alan Boswell, Romero, Caravan Guard — on nothing more capital-intensive than people and renewals.
2. That is exactly why the buyers came — and why their own accounts bleed. PIB lost £47.8M on £530M; Howden’s and Ardonagh’s group companies lost £569M and £473M while their broking subsidiaries stayed profitable. Debt and goodwill amortisation, not broking, produce the industry’s headline losses.
3. The personal-lines machines are the quiet giants — the brand-and-panel businesses (the AA, GoCompare, Simply Business) print 25–40% margins, while the integrated distributors (Hastings, 1st Central) run thinner entity margins but grow faster.
4. The mid-market is the healthiest tier — the £25–100M band is 93% profitable, the strongest on the map, and it is precisely the consolidators’ shopping aisle.
5. The new blood is MGAs and insurtech distribution — the fastest growers underwrite on others’ capital or sell direct at thin margins; their revenue accounting is different, and so is the way you should read their numbers.

Methodology and caveats

This covers the UK insurance-distribution and auxiliary companies that publish a full profit-and-loss — brokers, agents, MGAs, price-comparison sites, claims specialists and the pensions advisory and administration layer; the long tail of small brokerages reports no figures and doesn’t appear. Underwriters are out of scope by design, and 54 entities that carry the industry’s classification but aren’t distribution businesses (mis-filed insurers, Lloyd’s capital vehicles, financing SPVs, in-house service companies) are excluded from every table and chart. Several large brokers hold their UK revenue in entities classified outside this map and appear only as labelled context. Entity accounts can carry intra-group income, so group subsidiaries’ profit lines are not clean operating margins; MGA margins swing with profit commission. Figures are as filed to the start of June 2026; a handful of companies — Howden’s group holding company (whose newest accounts cover an awkward 15-month period to December 2025), GoCompare, the AA, Avantia and Romero — filed newer accounts later that month, after our snapshot. Figures are approximate and business descriptions are directional. This is analysis, not financial advice — verify any specific figure against the company’s own accounts.
