As well as saving money on your energy bills, microgeneration can also help you make money if you plan on selling your excess energy to the national grid. Microgeneration is typically better for the environment as most installations will use renewable energy sources such as solar panels.
The UK government also runs a Renewable Heat Incentive scheme that giving you the chance to earn quarterly payments for up to 7 years. The amount you get will depend on the amount of renewable energy you produce, but it can be a great incentive to switch to a renewable source today.
