Who we share it with.
Only the people needed to do the work: our structural engineers, architects, party wall surveyors, building control bodies and warranty providers (LABC) when you instruct us; our IT and service providers (Wix — website hosting and forms; Google — analytics and business email; Typeform — estimate tool; our accountancy software); and authorities where the law requires. All providers are bound by contract to protect your data. Some providers store data outside the UK (for example Wix and Google in the USA); transfers are covered by the UK International Data Transfer Agreement or UK adequacy regulations.

Under UK GDPR you can ask us for a copy of your data, ask us to correct or delete it, restrict or object to how we use it, and receive it in a portable form. Where we rely on consent you can withdraw it at any time. Email info@lcclconstruction.co.uk; we respond within one month. If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office (ico.org.uk, 0303 123 1113).
Marketing.
We only send marketing emails if you have asked for them or you are an existing client and have not opted out. Every email has an unsubscribe link.

Data is held in access-controlled cloud services with encryption in transit and at rest. We keep only what we need for the periods above, then delete it.
