The one cookie we set

planc_access is set only after you pay, or when you open the private link on your receipt. It holds a signed list of the plans and portfolio you've bought, so this browser can open them without a sign-in. It lasts 400 days. It's strictly necessary for the service you asked for, so the law doesn't require us to ask first, and we don't show a cookie banner.

Deleting it doesn't lose anything you've bought: open the link on your receipt to get it back. See your plans.

Plan C gives guidance based on your home's published EPC. It isn't legal, financial or surveying advice, an EPC assessment or a quote. Read before you rely on a plan.
