Useful things to include

For a correction: the page, the numbers you entered and what you expected.
For a new tool: the job it would help with and how you work it out today.
For builders' merchants and trade bodies: we are happy to talk about embedding calculators on your site.

We cannot give advice on individual projects. For structural or regulatory questions, contact your local Building Control body or a qualified professional.
