Tenant at Oak Lane is 2 months behind. What can I do?
Not Ground 8 yet, that needs three months since 1 May 2026. You can serve on Ground 10 today with four weeks' notice. Want me to draft it and send a final arrears letter first?
Yes, letter first. And put the rent up to £1,450 from January.
Arrears letter sent, Section 13 drafted for 1 Jan 2027
Done. Letter emailed and logged. Section 13 is drafted for £1,450 from 1 January, that is within the two months' notice and the once-a-year rule. Sign it here when ready.

The idea

Not another dashboard.

You do not log in and click through forms. You tell Ace what happened and it does the admin. Same Ace wherever you are.

On the site

Open the chat and talk. Ace has your properties, tenancies, certificates and figures in front of it.

In the app

Photograph a receipt or a gas certificate on the doorstep. Ace files it before you are back in the car.

On WhatsApp next

Message Ace the way you message your plumber. Same answers, same records, no app to open.

What Ace does

Ask it. Send it. Done.

Ask anything

"Can I evict for six weeks' arrears?" "What did Oak Lane make this year?" Answers from UK law and your own records, with the source they came from.

Send it, do not type it

Photograph a receipt or a certificate. Forward a bank statement to your own landlord-os.com address. Ace files every line against the right property and asks about anything it cannot place.

Ace reads your property postcodes and tells you which of these apply, and when. PRS registration is set by where the property is, not where you live.

Built in the UK

Works wherever your property is.

England, Wales, Scotland and Northern Ireland each get their own rules. A property anywhere else gets its own currency, the map and Ace's notes on local law, where we have them.

Where we have no notes, Ace still tracks the rent, documents, tasks and maintenance, and says plainly that it cannot advise on that country's law. The UK tax tools cover UK property only.

Grounded

Ask it what you would ask a solicitor.

My tenant is two months behind. Can I serve notice?
Ace

Not on Ground 8 yet. Since 1 May 2026 it needs three months' arrears at the notice date and again at the hearing, with four weeks' notice. Arrears caused by a Universal Credit delay do not count. You can serve on Ground 10 now, and I can draft it from the Maple Road tenancy.

Do I have to register on the PRS database?
Ace

Yes, every private landlord in England, one entry per property. It opens region by region from 15 December 2026, West Midlands first. Both your Birmingham flats fall in that first window. It is set by where the property is, not where you live. I will remind you a month before.
