Everything managed for you — at no cost to your business
Business energy, water and business rates cost management with nothing to pay. We manage your supplier accounts, audit every bill, sign and file the paperwork, and recover what you have been overcharged. You stay in control and can withdraw access at any time.
No fee to your business
No subscription, set-up fee or minimum term. Suppliers pay us, you never do.
We manage your supplier accounts
Confirm your supplier names and online logins once — encrypted, masked and cancellable in one click — and we work your accounts directly.
Overcharges eradicated at source
Every bill line audited: wrong unit rates, out-of-contract rates, estimated reads, duplicate standing charges, VAT and CCL — recovered up to six years back.
Sign once, digitally
Type your name to sign your Letter of Authority. Every signature carries a DocuSign-style certificate of authenticity with time, IP and device.
Signed PDFs retained and shared
Your signed LOA is stored as a PDF, emailed to you and issued to every supplier with your account numbers and business name on the subject line.
Readings and usage tracked
Submit readings from your phone or let us post them into your supplier account, so you are billed on actuals and never estimates.
Renewals never missed
We watch contract end dates and negotiate whole-of-market before any out-of-contract rollover can bite.
Disputes handled with evidence
Raise a challenge with supporting documents attached; we build and send the evidence pack to the supplier and chase it to resolution.
