We’re Sumer, your business champion
We’re a collaboration of the best in business services. We bring together the indispensable value of leading regional practices with the tech, scale and breadth of expertise that only a national organisation can muster. We call this ‘The Power of Collaboration’ – an approach that delivers growth for our entire organisation and all the businesses we serve.

But what does that mean?
First and foremost, it means we champion small to medium-sized businesses across the UK and Ireland.

From farmers to tech firms, retailers to charities - they are the businesses at the heart of our economy and communities. To us, they’re heroes.

To give them the support they deserve, we believe we need to do more than the established players that have gone before us.
