What we'd love to hear about

• Out-of-date HMRC, Ofgem, NS&I, ONS or Land Registry figures — we update annually but flag if you spot drift earlier.
• Bugs in the interactive calculators (wrong result for a specific input).
• Calculator suggestions — especially UK-specific situations not yet covered.
• Editorial feedback on worked examples or methodology pages.

We don't reply to general ‘please link to my site’ outreach.
