We’ve built a property management tool for small landlords?

Hello Property118 readers: I’m William Harford. I co-founded Harthing with Neil Carthy and Adam Saul.

We’ve built a property management platform specifically designed for landlords with small portfolios that they’re self-managing, and are trying to keep up with the endless stream of new regulations and tax requirements www.harthing.co.uk.

Between us, we have over 50 years in financial services, two chartered accountants, a Cambridge mathematician building the platform, and Adam is even a director of Rochdale AFC. All three of us are landlords who self-manage. We built this because the tools available for someone managing one or two properties without a letting agent appear to have gaps helpful to landlords.

We have tried to build something that is intuitive and helps landlords deal with this increased burden of maintenance, compliance, finances, and documents in one place, everything timestamped and Making Tax Digital categorised.

The idea is that your records should prove you’ve been managing your property properly, and producing that proof shouldn’t require an archaeology project through your inbox.

What’s live when we launch on 12 May:
• Property records, maintenance logging, compliance tracking, document storage
• Financial transactions categorised for MTD from the point of entry
• Immutable Accountability Record — every action hash-chained, nothing editable or backdatable
• Evidence Bundle — one click, full chronological proof of everything you’ve done for a property
• Compliance dashboard with expiry alerts

It does use AI, and it reads your gas cert and pulls the expiry date, so you don’t have to type it. It doesn’t have a name badge, and it doesn’t offer opinions.

I have two questions for readers:

Where do you actually keep your gas safety certificates right now, and could you find one in under two minutes if someone asked?

And with MTD now live, Section 21 going on 1 May, and Awaab’s Law on the horizon, do the tools that exist feel adequate?

Did you know you’ve got until 31 May to serve the official GOV.UK Information Sheet to every existing tenant, or it’s a £7,000 fine?

I am happy to answer questions about what we’ve built, and happy to be told we’ve missed something obvious.

Many thanks

William Harford
