Common questions
Are these calculators the same rules as SignWise paid documents?
Yes. Each tool runs the same deterministic @signwise/calc rules as the matching SignWise questionnaire, so dates, caps, and compliance flags align with what you would get when you start a document from the calculator.
Which statutes do the England landlord tools cover?
The hub covers Housing Act 1988 Section 13 (Form 4A), Tenant Fees Act 2019 deposit caps, Housing Act 2004 section 213 protection deadlines, and Renters' Rights Act 2025 Phase 1 duties under SI 2026/324 and related commencement orders.
Can I pre-fill my answers into a SignWise case?
Every calculator includes a CTA that opens /start with sanitised query parameters or a hidden prefill payload, mapping into RI, TA, WS, or LA question IDs so you can review and pay when ready.
Is this legal advice?
No. These are statutory self-help calculators for England private landlords. They do not replace tailored legal advice; use a qualified adviser for your facts.
