The problem

The dates landlords actually miss

Most portfolio losses come from admin slips, not bad investments. OnTop closes that gap.

Expired certificates

Missing gas or electrical deadlines means fines up to £30k, voided insurance, and unenforceable tenancies.

Spreadsheet sprawl

Juggling renewal emails, contractor texts, and outdated tracker sheets means there is never one source of truth.

Stale rents & rates

Rent reviews skipped for years quietly cost more than any compliance fine — and re-mortgages slip onto SVR overnight.

How it works

A landlord system for the dates that protect income

Three connected workflows — one calm dashboard.

Compliance

Never miss another deadline

Track every gas and electrical certificate, automatically. Get reminders weeks before — not days after.

  • Monthly summaries by email
  • Per-property expiry rings, at a glance
  • Drag-and-drop certificate uploads

Calm replaces panic

"I used to dread the start of every quarter. OnTop just tells me what is coming, when, and where to click. The gas certificate panic is gone."

FAQ

Frequently asked questions

How quickly can I get started?

You can set up your first property and upload certificates in under five minutes. Drag a PDF onto a property, set the expiry, you are done.

What file formats do you accept for certificates?

PDF, JPG, PNG, and most common document formats. You can also take photos with your phone and they upload directly.

Can my contractors access the system?

Contractors receive email notifications when renewals are approaching, but they do not need accounts or access to your private property data.

Is my property data secure?

Absolutely. We use bank-grade encryption and never share your data with third parties. Your portfolio information stays private.

What happens if I exceed my plan's property limit?

Your existing properties stay accessible. You will be prompted to upgrade before adding more, with no surprise charges.
