- To run and improve our business and keep our website secure. Legal basis: our legitimate interests.
We do not sell your information, and we do not send marketing emails unless you have asked us to.
Who we share it with
- Service providers who work for us, such as our website host, our email provider and the specialist software we use to design systems, price them and manage installations.
- Certification and scheme bodies where your installation requires it, such as MCS, NICEIC and RECC, your electricity network operator and the government body that administers any grant you claim.
- The Green Geeks Ltd, a separate company that installs heat pumps, but only if you ask us about a heat pump.
- Professional advisers, insurers and authorities where the law requires it.
Some of our service providers store data outside the UK. Where they do, we rely on safeguards recognised under UK data protection law, such as adequacy regulations or approved contract terms.
How long we keep it
If your enquiry does not go ahead, we delete your details within 12 months. If you become a customer, we keep your records for the life of your installation’s warranties and for at least six years after our last work for you, to meet tax and legal requirements.
Your rights
Under UK data protection law you can ask us for a copy of your information, ask us to correct or delete it, ask us to restrict how we use it, object to our use of it, and ask us to transfer it to another organisation. To use any of these rights, email sales@pieng.co.uk. We will reply within one month.
