What you can do in LeaseCheck on the web
Line-item charge ledger
Enter each year's demand line by line — management fee, insurance, cleaning, repairs, reserve fund — and see the year-on-year rise per item, per category and in total.
Statutory red-flag checker
The real four checks: Section 20 consultation on works over £250, the s.20B 18-month rule, the s.21B summary of rights, and Sch.11 admin charges. Answers are pre-filled from the dates in your ledger and each finding cites its statute.
Section 20 consultation tracker
Notice of Intention, estimates stage, award — with the 30-day observation deadline counted for each stage so you never lose a right by missing a date.
Letter library with response clocks
Section 21 summary-of-costs, Section 22 inspection, follow-up-after-silence and formal dispute letters, generated with your details, dated, logged, and tracked against the statutory reply deadline.
Tribunal evidence binder
Numbered, dated exhibits with an auto-generated ledger summary, correspondence log and findings list, exported as a First-tier Tribunal binder with cover page and exhibit index.
Plain-English rights reference
All nine rights — s.19 reasonableness, s.20, s.20B, s.21, s.22, s.21B, ss.47–48, s.27A and Sch.11 admin charges — with what the law says, what it means, and the practical move.

Questions
Is the web version of LeaseCheck free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the LeaseCheck iPhone app?+
The iPhone app exports the binder and each letter as a paginated A4 PDF; the web version copies or downloads them as formatted text you can paste into a document. Exhibits are titles, dates and notes — the iPhone app attaches the photograph to each exhibit and embeds it in the PDF. Statutory deadlines are shown as live countdowns rather than local notifications, because a browser tab cannot schedule an alert weeks out. LeaseCheck covers England and Wales only, and is a record-keeping and rights-reference tool, not legal advice.
