What to include
Reporting an error

The calculator name, the values you entered, and what result you got vs what you expected. A screenshot helps if the issue is visual.

Suggesting a calculator

What you're trying to calculate and why the existing tools don't cover it. If there's a UK standard or specification it should follow, mention it.

General feedback

Anything is useful — what's working, what isn't, something that's confusing, a feature that would save you time on site.
