About

SUMS – Southern Utilities Management Services helps UK businesses reduce commercial electricity and gas costs through expert procurement and contract management.Originally founded in 2018 as UK Payment Services, the business was repositioned and rebranded as SUMS in 2025. SUMS was established to provide commercially disciplined utility procurement for organisations that value clarity, cost control and accountability.We work with business owners, managing agents and property portfolios who require more than a transactional broker. Our focus is simple: secure competitive supply agreements, reduce risk exposure and ensure contracts are structured correctly from the outset.We operate transparently, communicate clearly and remain present throughout the life of every agreement — not just at renewal.Get in touch!

SCOPE

We negotiate gas, electricity and water contracts for businesses of all sizes — from single sites to large portfolios.

Gas

We structure gas supply agreements to provide price stability, clarity of terms and appropriate contract length aligned to consumption profile and risk appetite.Whether pricing is sourced via disciplined matrix comparison or through a bespoke tender process for higher-volume or multi-site portfolios, our objective remains the same: secure competitive market rates without exposing clients to unnecessary contractual risk.We also provide ongoing oversight where required, ensuring supply arrangements remain aligned with operational changes and tenancy movements.

Electric

Electricity procurement requires close attention to market timing, load profile and supplier performance. We assess consumption patterns and contract structure to ensure pricing strategy reflects both operational demand and budget expectations.For larger sites and portfolios, we can run structured market exercises to test supplier appetite and secure terms that balance competitive rates with service reliability. The aim is not simply to achieve a low headline price, but to secure a supply agreement that performs over its full term.

Multi-Site/Meter

Coordinated multi-site/meter energy management to reduce cost, risk and administrative burden.Managing multiple sites or meters introduces administrative complexity, fragmented contract positions and increased exposure to renewal risk. We provide coordinated oversight across portfolios to ensure supply arrangements are aligned, renewal dates are monitored and commercial terms remain consistent.From single business owners with several properties to managing agents overseeing larger estates, we centralise procurement strategy and provide a single point of accountability. The result is reduced administrative burden, improved visibility and greater commercial control across the portfolio.

Water

Water supply is often overlooked, yet contract structure and billing accuracy can materially affect operating costs over time. We review existing arrangements to ensure tariffs are appropriate, meter data is accurate and supply agreements are aligned with the wider energy strategy.Where required, we coordinate supplier engagement and support changes of tenancy, consolidations or account restructures — ensuring water procurement is handled with the same discipline as gas and electricity.

Ongoing Energy Management

Energy procurement does not end at contract signature. Changes in tenancy, consumption shifts, billing discrepancies and renewal exposure can erode the value of an otherwise well-structured agreement.We remain engaged beyond placement where required — monitoring renewal timelines, managing supplier liaison, validating bills, resolving disputes and coordinating meter changes or tenancy transitions. This ensures supply arrangements continue to perform as intended throughout their term.Support can also extend to EV charging infrastructure and on-site generation (Solar) where appropriate, maintaining a coordinated approach across wider energy requirements.For portfolio clients, this ongoing oversight provides continuity, accountability and a single point of contact — reducing administrative burden while maintaining commercial control.Get in touch!

APPROACH

We price in two ways — fast matrix pricing for straightforward renewals, and structured tenders for larger or more complex portfolios.

Matrix Pricing

For single sites and simpler renewals, we compare the market quickly and transparently to secure the best rate available — then sanity-check supplier service before we recommend anything.

Structured Tender

For higher consumption or multi-site portfolios, we run a structured tender to test supplier appetite, lock in commercial terms, and align contract structure to budget, risk and operational realities.
