We recommend you use an installer who is certified under the Microgeneration Certification Scheme (MCS) and uses MCS-certified products.
All installers or suppliers should be able to provide a detailed breakdown of the specification and costs of their proposed system. They should also be able to:
- explain how they have calculated the size of the system to be appropriate for your needs
- supply clear information and operating instructions
- explain how you should maintain your system
- provide an estimate of how much heat and electricity will be generated by any proposed system, and illustrate what this means in terms of your current energy needs
- provide an estimate of the savings you could make after installation
