Our Services

Our Business Heat (CHP) team offers a number of services to our customers. These include:

Invoicing and Contract Management

Each of our CHP sites has a nominated Contract Manager who oversees the day-to-day implementation of all contractual provisions and provides services such as producing monthly invoices and supplying monthly data showing energy consumption and prices. We can also offer a commercial structure for negotiations and help customers to adapt to their changing needs.

Operating and Maintaining

Our CHP portfolio includes two Operations and Maintenance contracts – one at the Kemsley site and one at Winnington. At these sites, E.ON CHP Operations runs and maintains the CHP asset offering the wealth of knowledge and experience gained through nearly 20 years in the field. Performance expertise also helps our customers understand how the plant can optimise efficiency. The Operations & Maintenance contracts are supported by E.ON’s specialist functions such as Engineering, Environment and Procurement. As with the other sites, a dedicated Contract Manager is on hand to manage the contract and offer services such as billing.

Energy Expertise

As a trusted energy partner, we can offer up-to-date energy policy and market knowledge. Contract Managers inform our customers of any relevant upcoming legislation and help them to become more energy efficient.


We complete annual accreditation submissions to the Combined Heat and Power Quality Assurance (CHPQA) programme for all of the plants supplying customers in our portfolio. This programme is run on behalf of The Department of Energy & Climate Change (DECC) and entitles CHP providers to exemption from the Climate Change Levy on fuel input to a good quality CHP plant. Since April 2013, the CHPQA process also provides relief from the UK Carbon Price Support tax for the proportion of input fuel that is used in producing heat.

Technical Expertise

Some of our CHP customers staff the plants on a day-to-day basis. We offer regular input from E.ON's CHP Operations team to give technical support. Customers also benefit from our technical expertise when assessing options for energy supply including maximising energy efficiency through CHP plant operation and their own processes.


We actively lobby through organisations such as the Combined Heat and Power Association and through our wider lobbying activities, contributing to government consultations on energy market reform.

Third Party Management

We also hold and manage contracts with third parties supporting the smooth operation of the CHP plant. These include District Network Operators, National Grid, Utilities and fuel suppliers – all of whom are vital to the successful operation of the plant and delivery of energy to our customers.
