Bespoke insurance without boundaries that adds real value to your business.

At Mainstay we are different – we actively seek clients where our expertise can add tangible benefit. Rather than providing off the shelf policies, we create insurance programmes that respond to the business needs of our clients. These programmes bend and flex as our clients grow and develop because things rarely stay the same in business.

We are not constrained by geographical location so if we are talking to you as a prospect it is likely that you are the kind of business where we feel we can make a real difference. If you found us, it probably means you operate in one of the sectors in which we specialise or you were seeking a broker determined to understand your needs.

Mainstay are proud to be an independent insurance broker; it means the advice we provide and the policies we purchase on your behalf are not influenced by a larger group or international owners. We are members of the Compass Network and this creates a best of both worlds scenario for our clients. The service and expertise you would expect from a smaller broker coupled with the resources and global reach of a major player.

When we say we specialise we really mean it and it’s demonstrable; our key specialisms are Life Science, the leisure industry, property owners, and professional indemnity, although these are not limitations and we have existing clients from most sectors. Our clients are serviced by experts with in-depth knowledge garnered over many years.

We truly believe that service is something that needs to be experienced to be appreciated and that only our clients can really express how different we are. We have included testimonials from them throughout our site.

We returned to Mainstay because we missed their expertise, enthusiasm, professional approach and personal touch. As expected, they immediately provided us with better cover at a very competitive price. We are confident that our insurances are properly arranged and well maintained.

I transferred my Professional Indemnity policy back to Mainstay immediately. It is good to know that appropriate insurance expertise is available to me again.
