How to Choose a Renewable Energy Provider

Always choose installers certified under the Microgeneration Certification Scheme, as this is required for many grants and export tariffs. Obtain several quotes, check warranties on panels, inverters and batteries, and ask for a detailed estimate of generation and savings. For heat pumps, ensure a proper heat loss survey is carried out.
