Contact EuroWattCalc

EuroWattCalc is maintained by a small, independent team. All enquiries go to one place: hello@eurowattcalc.com.

What we can help with

• Calculation issues — a result that looks wrong, a formula that doesn't match the methodology page, or a unit conversion that seems off.
• Content corrections — unclear wording, an outdated reference, or a factual error in a guide or country page.
• Technical problems — a broken page, a calculator that won't update, or a display issue on a specific browser or device.
• Privacy and data requests — see the Privacy Policy for what we hold and how to ask about it.
• Everything else — general feedback, partnership enquiries or press questions are all welcome at the same address.

Useful details to include

• The page URL where you noticed the issue.
• The values you entered into the calculator, if relevant.
• The result you expected, and why.
• Your browser or device, if the problem looks technical.

What to expect

We read every message. As a small independent site we can't promise a fixed response time, but calculation errors and broken pages are treated as priority fixes once reported and verified.

For privacy reasons, please don't send account numbers, full energy bills, or other sensitive personal information by email.
