About Us:
Launched in 2018 Jensten is one of the UK's largest independent broking groups. Growing organically and through strategic acquisition we now place over £650m GWP into the market via our retail insurance broking, Lloyd's and London Market broking, and specialist underwriting arms.
We fill the void in the market between a consolidator and a provincial broker. We have the scale, ambition and expertise to stand out, but the people, culture and entrepreneurial DNA to maintain our client focus. Which is why we are not just one of the leading independent broking groups, we are one of the most exciting too.
And that is why you should join us!
