Simplifying Utilities.
Powering Your Business

We know this site looks simple. It was a conscious decision. At SUMS, we don’t do waffle, filler, or industry jargon. We believe in clarity. So we created a "lite" site.This is a quick, honest intro to who we are, what we do, and how to get in touch. No bells, no whistles, just business done right.

About SUMS

Meet SUMSThis was the brainchild of Steve Green, a Yorkshire-born, Sussex-based utility broker with a 30 year background running hospitality and visitor attractions internationally. He took a sabbatical in 2018 and quickly saw his experience could help SME businesses.Through organic growth, what was UK Payment Services, drifted more naturally into Utilities. “UK Payment Services” was no longer a fit for purpose name. Keeping the same ethos, Southern Utilities Management Services Ltd was developed.We know how frustrating utility bills can be. So SUMS was created to make things simpler for business owners, who just want clarity and control without wasting hours on hold.At SUMS, we're not into sales patter. Just honest advice, quick wins, and lasting results.
