Our Story

“I’ve spent nearly 40 years in insurance, and one thing has never changed for me: when something goes wrong, people don’t want a debate about policy wording – they want someone in their corner.

That belief is what Whetstone is built on. I spent two decades building a healthcare practice at Lockton, working with some brilliant people. But I always knew I wanted to do something different – a business where client advocacy isn’t a value written on a wall, it’s the reason we exist.

Whetstone has been founded on employee ownership. Our team has real skin in the game and this shows in the service levels they provide. Our client retention rate is 95%, and frankly, the team is obsessed with making it higher.

We’re building something with exceptional people – 25 and counting! Many of our team have worked inside healthcare and clinical environments themselves, so they understand the pressures our clients face from the inside out. Backed by a legally trained clinical team and the kind of infrastructure that puts its arms around clients when they need it most, our aim isn’t to be just another intermediary – it’s to be a genuine alternative. One that gives healthcare providers clarity, support and confidence, so they can focus on what matters most: caring for patients.”

Doing the right thing

For us, doing the right thing extends beyond our commitment to clients and into the wider community.  Here are a few of the ways Whetstone supports charitable initiatives both at home and abroad.

Dentaid – the dental charity

Whetstone is proud to partner with Dentaid The Dental Charity as the supplier of its vicarious liability insurance through Densura.

Dentaid’s mobile charity dental units travel across the country to provide oral health advice and treatment to people facing homelessness, harm, poverty and abuse across the UK.

Our vicarious liability scheme ensures that every one of the volunteer dentists and dental nurses who work for Dentaid are properly protected.
That means they can continue supporting those most in need of life-changing care in confidence – helping to free vulnerable people from pain and make a real difference to their lives.

The Magic Dentist

We support The Magic Dentist, an initiative bringing oral health education into UK schools and providing access to dental care for children most in need.  The charity aims to reach as many children as possible to teach them about oral and systemic health and alleviate immediate pain, with the overall aim of reducing school absenteeism and admissions to hospital.

IcFEM Dreamland Mission

We’re compensating for our carbon emissions through this scheme which has more than 30,000 trees planted across Bungoma County, western Kenya. As well as providing an income for farmers, every tree is helping remove carbon from the atmosphere.
