Letted vs Arthur Online:
organising work vs doing it
Letted is an AI property management platform for UK landlords — and, through its agency mode, for letting agencies managing many landlords. Arthur Online is workflow software your team operates. Here's the honest comparison.
Letted
That’s us
AI that does the admin for self-managing landlords — tenant messages answered, repairs coordinated, rent and compliance tracked. Free for your first property.
Arthur Online
Workflow software
Aareon-owned workflow software with portals for tenants, owners and contractors, plus full client accounting. From £70/month with 50 units included — your team still does the work.
Arthur organises the work for your team to do. Letted's AI does the work itself — for landlords, and for agencies through its multi-landlord agency mode with role-based team access.
The real difference: organising vs doing
Who it's built for
Arthur Online (owned by Aareon) is workflow software with portals for tenants, owners and contractors. Letted serves self-managing landlords — and letting agencies, through an agency mode that manages multiple landlords with role-based access and team logins.
Software you operate
Arthur gives you configurable workflows, task queues and reminders. They're powerful, but a person still answers the tenants, chases the rent and books the contractors.
AI that operates for you
Letted's AI answers tenant messages itself, coordinates repairs itself, and starts compliance renewals itself — asking you only when a decision or payment is needed.
Priced for your size
Arthur starts at £70/month including 50 units — sensible for an agency, heavy for a landlord with four flats. Letted's first property is free, then a flat £20/month covers up to 30.

Common questions
Arthur Online is capable software, but it's priced for scale: plans start at £70/month billed annually with 50 units included. A landlord with a handful of properties pays for a lot of capability they won't use — and the work itself still lands on a person. Letted covers the same ground from free, with the AI doing the admin.
Arthur Online is workflow automation software — it routes tasks, sends reminders and keeps records, but the work itself (answering tenants, chasing contractors, handling queries) is done by your team. Letted takes the opposite approach: its AI performs the administrative work directly and brings you in only for approvals and decisions.
Letted. Arthur Online's entry plan is £70/month (billed annually, 50 units included), so under 30 properties you're paying an agency-scale price. Letted covers your first property free and up to 30 properties for a flat £20/month.
Yes. Add your properties, and Letted collects the existing documents, verifies them and flags any gaps — there's no bulk migration project. Most landlords are fully set up within a couple of hours. Agencies switch too: Letted's agency mode manages every landlord on your rent roll in one place, with role-based access and logins for each team member.
Yes. Letted has a dedicated agency mode: an agency manages multiple landlords' portfolios from one account, with full authentication, role-based permission controls and separate logins for each team member — while the AI handles the tenant messages, repairs and compliance tracking underneath. That's the difference: Arthur gives your team a system to work in; Letted shrinks the work your team has to do.
