Details
You should be aware of your ongoing responsibilities after registering your heat networks.
Your regulatory obligations
Registration does not replace the need to understand and comply with the regulatory requirements that apply to heat network suppliers and operators.
You should make sure you’re familiar with the heat network authorisation conditions, which set out the rules you must follow. You’re responsible for understanding how these conditions apply to your organisation and for complying with them.
