Most landlord spreadsheets still price a world with section 21 in it — and that world ended on 1 May 2026. Five things changed; each one moves a number in your model. This free guide gives you the five steps, with every date checkable against the primary source.
Rebuilding your void and arrears assumptions for grounds-based possession; the £40,000-per-breach penalty exposure and 24-month rent repayment orders; the retrofit cost printed on your own EPC that almost nobody reads; the 6 April 2027 property-income rates (22%, 42% and 47%) and the re-run to do this autumn; and which side of the company line to be on by 2027.
Because every claim in it is checkable, and checking it is the best introduction to how this practice works. The guide ends with a ten-minute call if you want the five steps run on your actual numbers — fixed fee, agreed in advance.
