About Us

Primassure was formed in 2007 to provide a specialist insurance broking service to the UK and international diamond and jewellery industry.
Our personal service and eye for detail was really well received and it wasn’t long before our clients were asking us to help them with their own personal insurances so in 2011 we purchased the well-regarded Brentwood Insurance Services.

Our expanded experienced team work with the full range of UK regulated insurers including Lloyd’s of London and are delighted to provide the same level of commitment and excellence to all of our clients, however large or small.
Whatever your insurance needs please give us a call. All of our friendly staff are based in the UK and if you prefer we will be delighted to welcome you personally to our offices to talk over your requirements.

We are FCA regulated and are an Associate Member of the National Association of Jewellers.
