An AI-Native Operating System for UK Landlords
Run your entire portfolio by chatting with Ace. Compliance, tenants, documents, accounts, listings, every UK landlord task handled by one AI agent with 36 purpose-built tools.
The UK Landlord Compliance Cliff
UK self-managing landlords are facing the toughest regulatory environment in a generation, and the existing tooling has not kept up:
Renters' Rights Act (Section 21 abolished, May 2026) rewrites the eviction rulebook
MTD for landlords becomes mandatory from 6 April 2026, spreadsheets are no longer compliant
67.5% of landlords cite legislation complexity as their biggest challenge
Average landlord age is 59, needs a tool that feels effortless, not another power-user app
Meet Ace, Run Your Whole Portfolio by Chatting
LandlordOS is an AI-native operating system built specifically for UK self-managing landlords. Ace, the in-app AI agent, runs the portfolio: add a property, log a rent payment, serve a Section 13, check MTD status, snap a photo of a faulty boiler, all from one chat, on any device. Behind the chat are 36 landlord-specific tools, full HMRC MTD integration, and live data feeds from HM Land Registry, EPC Register, the Environment Agency, Police, and Companies House. Photo recognition handles property handovers and inventory: snap a washing machine, Ace logs it; snap a damaged wall, Ace flags it.
