Thinking of installing renewables?

Renewable energy is generated from natural resources such as the sun, wind, and water, using technology which ensures that the energy stores are naturally replenished. Instead of buying all of your energy from suppliers, you can install renewables technology to generate your own.

If you’re thinking about a home renewables system,  you should first ensure your home is as energy efficient as it can be. This will help you get the most out of your new system. Think about insulating your property wherever you can, and using your appliances, lighting and water more efficiently.

Once you’ve thought about which technology would best suit your home and your needs, you can start to research the options in more detail. Weigh up the products that are available, their costs, the size of systems and any special requirements for installation.
