The lease share calculator, lease-extension cost guide, Section 20 planner and demand-paperwork worksheet keep entries in the current tab without autosaving or sending them to building trust. The cost guide sends your postcode to HM Land Registry only when you request recorded sales.

The Resident Quick Case, demand checker and budget planner autosave in this browser on this device. A route-level clear removes only that route. Delete the whole local case removes shared facts, evidence, artifacts and recovery copies.
Copy, download and print actions let you keep an output. Check it before sharing. Opening LEASE-iQ or another source takes you to a separate service; nothing is pasted or submitted automatically.
The tools organise the information you enter. They do not read your lease or decide whether a charge is payable.
Building records
Building records need more than one score.
The lease, company records, safety information and management records answer different questions. Keep them separate, then connect them to the decision you actually need to make.
