Harthing is the only platform where being a good landlord and proving you were are the same thing. Every action timestamped. Every repair tracked. Every obligation met — and on the record.
No more hunting through shoeboxes. No more hoping you saved that receipt. Just a single continuous record — your side of the story, built as you manage — ready the moment you need it.Good letting, on the record.
From April 2026, MTD requires quarterly digital tax returns. From May 2026, Section 21 'no-fault' evictions are abolished — every dispute now requires documented evidence. Both deadlines are real. Neither is optional. The landlords who have a proper record will be fine. The ones relying on WhatsApp threads and memory won't be.
"You're running a property business through WhatsApp screenshots, a folder called 'TAX STUFF (2)', and the vague memory that the gas certificate was definitely renewed at some point last year. Probably."
— Every self-managing landlord we've spoken to, more or less
You're not the landlord the newspapers write about. You fix what breaks, you file what's due, and you try to do right by the people living in your property. Harthing is here to make sure that's on the record.
It replaces the spreadsheets, WhatsApp threads, and shoeboxes with a single platform that manages your properties and builds your compliance record at the same time. Not as two separate jobs — as the same job.
Not artificially intelligent. Just actually organised.
Upload a gas safety certificate. We'll read it, file it, log the expiry, and remind you before it lapses. Upload a tenancy agreement — we'll extract the names, the dates, the rent amount, and the break clauses. You confirm what's right. That's it. No chatbot. No AI assistant with a name and a personality. Just a platform that reads your documents so you don't have to type everything twice.
Every certificate, every expiry date, every obligation — tracked and surfaced before it becomes a problem. Gas safety. EICR. EPC. Deposit protection. Harthing knows what's due, when it's due, and what happens if you miss it.
Income and expenses captured as they happen, auto-categorised against HMRC allowable types. Quarterly MTD summaries generated automatically — ready to submit or hand to your accountant. No end-of-year scramble.
From report to resolution, every repair is logged with timestamps, costs, and contractor details. Awaab's Law timers start automatically. You'll never have to reconstruct a timeline from memory again.
Everything above feeds into one continuous, timestamped record of how you managed your properties. Not a report you generate — a record that builds itself. When a tribunal, an Ombudsman, or HMRC asks "can you prove it?", you can.
Harthing is the landlord side. Letterlea — the tenant app — is coming. We're building it on the same database, not as a bolt-on. When it arrives, your tenants will be able to report maintenance, see repair progress, and access their tenancy documents — all in one place. Every interaction they have will automatically update your Harthing dashboard and strengthen your Accountability Record.
Why does that matter? Because one-sided records are self-serving. In a tribunal, a landlord's own logs prove what the landlord says happened. When both sides contribute to the same record, it proves what actually happened. That's not a feature — it's a fundamentally different kind of evidence.
Harthing works perfectly without Letterlea. But it works even better with it. We'd rather ship it right than ship it first.
No jokes in this section. These are legal obligations with financial penalties. We take them as seriously as HMRC does.
Landlords with property income over £50,000 must maintain digital records and submit quarterly updates. Dropping to £30,000 from April 2027. Penalties up to £1,000 per filing period.
Fixed response timelines: investigate within 14 calendar days. Emergency repairs within 24 hours. All other repairs commenced within 7 days. Legal consequences for failure.
Section 21 'no-fault' evictions abolished from 1 May 2026. Landlord Ombudsman introduced. Property portal created. Every dispute now requires documented evidence of fair process.
Every action you take in Harthing is timestamped and immutable. Respond to a maintenance report — logged. Upload a gas safety certificate — logged. Record a repair cost — logged. You're not filling in a compliance checklist. You're managing your properties, and the record builds itself as you go.
That's the difference between Harthing and a folder full of documents. A folder proves you saved something. The Accountability Record proves when you did it, what you did about it, and that nobody changed the record after the fact. When a tribunal, an Ombudsman, or HMRC asks "can you prove it?" — you can.
Not a report you generate. A record that builds itself.
Three bands, matched to how landlords actually work — not arbitrary tiers. Whether you fell into one property or chose to build a portfolio, you pay one price for the full platform. Every feature included, every time.
For the accidental landlord. You inherited a flat, kept your old place, or ended up here by circumstance. Compliance dashboard, MTD-ready finances, maintenance tracking, and the Accountability Record — everything you need to manage properly and prove it.
You chose to grow. Multiple properties, multiple tenants, multiple compliance deadlines. Harthing keeps all of it in one place — every property, every record, every obligation. Same platform, same features.
You're running a business. At 12 properties, that's £3 per property per month. The Accountability Record at this scale isn't just useful — it's the difference between "I think I responded" and "here's the timestamped proof that I did."
