We recommend always using an industry-accredited supplier and installer. A database of accredited suppliers and installers can be found on the Energywise website. Ask what post-installation service or warranties they provide.
As part of their quote, installers should include an assessment of your house, roof orientation, and any structural support requirements for the cylinder. Ask them about their specific experience in installing systems in circumstances similar to yours, for example if you have a two-storey house, or if you live close to the sea or in a very exposed place.
If you choose to have a system with a cylinder on the roof, the installer will need to do an assessment of any structural requirements to ensure the weight of the cylinder is supported. If you have a system with just collector panels on the roof, this is not likely to be a concern.
Regardless of which type of system you choose, the installation will need to comply with the New Zealand Building Code and that means you will need a Building Consent from your local council.
Obtain quotes and information from several industry-accredited suppliers or installers to ensure you get the best system at a competitive price.

"My mother (74) got a renewal letter from her insurance company for her car insurance, wanting $570. After reading
your article on car insurance, I contacted one of the companies you recommended, who quoted her $318 for the same
level of cover. I just wanted to stay thank you very much for your article, as it has saved my mother a substantial amount of money".
