An MGA built for brokers — that built its own engine.
One Underwriting holds delegated authority from a panel of respected insurers, and runs it all on BONUS — a platform we own end to end, built from the broker’s side of the desk.
Our story
We rebuilt broker insurance around the broker.
Too many systems were built for the insurer, with the broker left to work around them. We took the opposite view.
BONUS — the Broker Online Underwriting System — is our answer: instant quotes, your own branding, your whole book on a live map, real underwriters behind genuine referrals, and the whole policy lifecycle in one place. Because we own the technology, when brokers tell us what would make their day easier, we can actually go and build it.
What we stand for
The principles behind every decision.
Broker-first, always
BONUS was built from the broker’s side of the desk. If it doesn’t make a broker’s day easier, it doesn’t ship.
Fair by design
Consistent, data-driven pricing and Fair Analysis mean the same risk gets the same answer — in line with Consumer Duty.
Your clients stay yours
We are the engine behind your brand. Your relationships are yours, and we never get between you and your client.
We own our tech
We built and own BONUS end to end — so when brokers ask for better, we can actually build it.
The people
Real people, on your side.
When you partner with us, you get people who pick up the phone and underwriters who make decisions — not a ticket queue.
The facts
Regulated, accountable, transparent.
