Editorial policy

Oliver Burton writes or reviews everything published here (see about BizBillCheck).

Sources

Tax rates, thresholds and regulations come from HMRC, GOV.UK, Ofgem or Ofcom and are linked with the date checked. Provider prices come from their own published price lists. Sector pages use either cited data or your own calculation, never an invented "typical bill".

Review cycle

Pages with money figures show when they were last reviewed and are rechecked at least every 90 days, plus whenever HMRC or Ofgem announces a change (for example, CCL rates each April).

Independence

Partners can't pay to change our content, rankings or calculator results.

Mistakes

Tell us at oliver@htmlstudio.co.uk. We'll check within five working days and, if we got something wrong, fix it and add a dated correction note to the page.
