About SwitchZero
A clearer way to manage costs and plan ahead.
Most organisations do not need another supplier. They need a clearer way to manage costs and plan ahead.
SwitchZero starts with commercial procurement, then looks at where further savings can be made through efficiency upgrades, solar PV, battery storage, monitoring and funding.
Our advice is independent, straightforward and based on how each organisation operates.

Discover SwitchZeroBusiness energy procurement
Start with the right commercial contract.
Gas and electricity contracts can have a major effect on operating costs, yet many organisations renew without enough time, information or market visibility.
We review contract end dates, consumption and meter information before comparing suitable commercial options. Terms and costs are presented clearly, with support through contracting and beyond.

Why SwitchZero
Helping organisations make better decisions.
Securing the right contract is one part of the picture. The next step is to understand usage, compare credible options and pursue changes that stand up commercially.
Independent procurement
Suitable suppliers and contract options are compared against usage, renewal dates and appetite for risk.
One joined-up service
Procurement, efficiency, solar, storage and monitoring can be considered together.
Continued support
Our involvement does not end when an agreement is signed.
Based on your organisation
Recommendations reflect sites, operating hours, budget and priorities, with no generic package.
The full cost picture
Separate improvements can contribute to a lower overall cost.
Every site is different. This illustration shows how procurement, consumption reduction and on-site generation may build on each other. It is not a saving promise and not every organisation will need every step.

Commercial decisions shaped around how the site operates.
Different loads, estates and operating windows need different procurement and project priorities.

Manufacturing
High process loads, shift patterns and production risk make timing, capacity and data especially important.
Explore the sector02Warehousing & Logistics
Large roofs, vehicle movements, refrigeration and extended operating hours create a distinctive mix of opportunities.
Explore the sector03Retail
Trading hours, refrigeration, lighting and distributed estates call for simple portfolio visibility and disciplined renewals.
Explore the sector04Hospitality
Guest comfort and year-round heat, hot water, catering and laundry loads leave little room for blunt cost-cutting.

Round-the-clock guest, hot-water, kitchen, laundry, lift and leisure loads need to be matched carefully to occupancy.

Read articleFrequently asked questions
Straight answers before the first call.
Commercial energy can become needlessly complicated. Here are the questions businesses ask us most often.
View all questionsWhat does a commercial energy broker do?+
A broker gathers your meter and contract information, approaches suitable suppliers and helps compare the commercial offers. The quality lies in the data, tender, explanation and ongoing support, not simply forwarding a price.
How far in advance can a business renew?+
Procurement windows vary by supplier, meter and market. Starting early gives time to verify information and decide when to request prices without being cornered by a deadline.
Does SwitchtoZerocharge a fee?+
The payment route will be explained before you proceed. Some work may be paid through supplier commission and some projects may use a separate agreed fee, depending on scope.
How is broker commission disclosed?+
Where commission applies, the disclosure route and available information are explained as part of the contracting process.
Can you manage multiple sites and meters?+
Yes. We can map meter details, end dates and usage to create a structured portfolio plan.
What is a Letter of Authority?+
It allows an appointed broker to request supply and contract information and approach suppliers for the stated purpose. It does not by itself authorise a new supply contract.
What happens after the contract is signed?+
We stay available for the agreed scope, help track key dates and support relevant supplier queries and additional cost-reduction discussions.
