Practise with sample bills. These are invented NI-style bills with the figures you need highlighted. They are not from real suppliers.
Emission factors come from the UK Government GHG Conversion Factors for Company Reporting 2026 (DESNZ, June 2026), using location-based UK grid electricity. This is a rough estimate for information only. It is not a verified carbon inventory or legal advice, and it does not include well-to-tank emissions or most Scope 3 categories.
