ResiShield: the compliance and risk engine for the Renters’ Rights Act.

If you let property in England, the rules you built your business on have changed. ResiShield is built to keep good landlords on the right side of the line, without a law degree or a compliance team of your own.

The Renters’ Rights Act 2025 received Royal Assent on 27 October 2025 and is commencing in phases. ResiShield is built around the Act itself, the government’s implementation guidance, and the existing open property-data sources, and is updated as each phase commences.

What is ResiShield and who is it for?

ResiShield is a compliance and risk engine for landlords, investors and agents operating under the Renters’ Rights Act 2025. It helps you recover possession to sell within the rules, scan a property or portfolio for compliance risk before you buy, and run the day-to-day of a tenancy with the discipline the new regime demands. It is in development; you can join the early-access waitlist today.

The new economics of letting

The Renters’ Rights Act 2025 changed the economics of being a landlord in this country. Section 21 is gone. Tenancies are periodic. Rent rises are capped, evidenced, and challengeable. Penalties run to £40,000. The amateur landlord with a shoebox of receipts is in real trouble. The disciplined operator is not. ResiShield is how the disciplined operator stays disciplined.

Three modules, one engine

What ResiShield does

Landlords selling

Exit Ramp Engine

Calculates the legal route to recover possession when you intend to sell. The system enforces the 12-month protection on Ground 1A before any notice is drafted, generates the compliant notice, and produces a marketing-window calendar so the property cannot accidentally be re-listed during the restricted period. Built to protect against the largest single penalty risk in the Act.

  • Confirms the legal route to recover possession for sale
  • Enforces the Ground 1A protection on possession before a notice is drafted
  • Generates the compliant possession notice
  • Produces a marketing-window calendar to prevent an accidental re-listing
  • Keeps a documented audit trail behind every decision

Investors and buyers

Due Diligence Scan

Scans a property or a portfolio against the new compliance picture before you commit. Flags missing PRS Database registrations, historical civil penalties and Rent Repayment Orders, and signals of past rental bidding practice. Translates each finding into a defensible price-adjustment recommendation backed by the underlying evidence.

  • Scans a single property or a whole portfolio before you commit
  • Flags missing PRS Database registrations
  • Surfaces historical civil penalties and Rent Repayment Orders

Landlords holding

Stayers Console

Manages the new Section 13 rent-review process, the periodic-tenancy structure, pet and tenant requests, and the maintenance triage that will sit under Awaab’s Law when it extends to the private rented sector. The day-to-day operating system for a small portfolio, designed to give a one-property landlord the discipline of an institutional one.

  • Runs the new Section 13 rent-review process end to end
  • Tracks the periodic-tenancy structure
  • Logs pet and tenant requests with a documented, defensible decision
  • Triages maintenance ahead of the Awaab’s Law extension
  • Gives a one-property landlord the discipline of an institutional one

Who it is for

Built for three kinds of landlord decision

Exiting landlords

You want to sell, and you want to recover possession cleanly and legally. ResiShield maps the route, enforces the protected period, and keeps you out of the most common and most expensive mistakes.

Capital buyers and investors

You are pricing risk before you commit. ResiShield scans a property or a portfolio for compliance gaps and past penalties, and turns each finding into a defensible adjustment to your offer.

Retaining landlords and portfolio operators

You are holding and operating. ResiShield runs the Section 13 process, the periodic tenancies, the requests and the maintenance triage, so a small portfolio runs with institutional discipline.

Module specifications

How each module works

Exit Ramp Engine

Where a landlord recovers possession in order to sell, the Act restricts re-letting and re-marketing for a protected period after possession is sought. ResiShield enforces that window before a notice is drafted, so a property cannot accidentally be re-listed inside the restricted period, which is one of the simplest ways to incur a penalty under the new regime.

Breaches of the Act can attract civil penalties of up to ÂŁ40,000, and tenants may apply for Rent Repayment Orders. Exact mechanisms and commencement dates are set out in the Act and its implementing regulations; ResiShield tracks them as they commence rather than asserting fixed dates here.

Due Diligence Scan

The Act introduces a PRS Database and a Landlord Ombudsman, expected from late 2026 onward. Due Diligence Scan checks a property or portfolio for missing registrations, a history of civil penalties or Rent Repayment Orders, and indicators of prior rental bidding, each translated into a defensible price-adjustment recommendation with the supporting evidence attached.

The scan is built on the same open-data structures used across the Property AI Lab, so each finding can be traced back to its source. It is decision support, not a valuation or legal opinion.

Stayers Console

Under the Act, rent increases are limited to once per year and must be served using the prescribed Section 13 process with the required notice; a tenant can refer the proposed rent to the First-tier Tribunal. Stayers Console runs that process, manages the periodic-tenancy structure, and logs pet and tenant requests with a documented, defensible decision.

It also prepares the maintenance triage that will sit under Awaab’s Law once it extends to the private rented sector, expected from late 2026 onward. ResiShield does not render live statutory calculations on this page; those belong inside the application when it launches.
