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.
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.
One dripping tap. Two happy people. Zero admin. And an immutable record that protects them both.
From 1 May 2026, every landlord dispute requires documented evidence. Deposit claims. Possession hearings. Ombudsman complaints. Right now, you're relying on WhatsApp threads, email inboxes, and the vague hope that you saved that receipt. The Accountability Record changes that.
Prove you responded to that damp report within 14 days. Prove you arranged a Gas Safe engineer. Prove you communicated clearly and fairly. The Accountability Record assembles itself as you manage — maintenance logs, communication history, compliance certificates, financial records — all timestamped, all immutable, all packaged into a court-ready or Ombudsman-ready evidence bundle when you need it.
When Letterlea arrives, your tenants will see exactly when you were notified, when you responded, and what you did about it. If you acted quickly, they'll know. If you didn't, they'll have proof. The same record that protects you protects them — and that's what makes it credible to a third party.
Same data. Both sides protected. That's not a feature — it's a fundamentally different relationship between landlord, tenant, and their shared regulatory reality. Harthing builds your side of that record from day one. Letterlea completes it.
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 property platform says the same things in the same font. We think you deserve better than corporate filler and stock photography of people holding keys.

You didn't plan to be a landlord. But here you are, with a shoebox full of receipts and a boiler that makes noises.
Gas safety certificate for 22 Maple Road expires on 14 September. That's 62 days. Want to book an inspection now, or shall we remind you at 30?
We couldn't save that expense just now. This usually sorts itself in a few seconds. Your data's safe — nothing lost.
22 Maple Road — kitchen tap, persistent drip. Reported by tenant 9:12am. AI triage: plumbing, non-emergency. Awaab's Law: 14 days.
Upload your documents — tenancy agreements, certificates, bank statements. We'll read them, pull out what matters, and ask you to confirm. Minutes, not a weekend.
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. Launch pricing — locked in for as long as you stay.
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."
Launching soon. Early access users get 12 months' free access to the full platform from the day pricing goes live. Just an invite when it's ready.
Most landlords signing up to Harthing have the same thing in common: a folder somewhere full of documents they haven't looked at since they filed them. Tenancy agreements. Gas safety certificates. Bank statements. Invoices from that boiler repair you still need to claim back.
That's exactly what we need to get you set up. Drag those files in — as many as you have, in whatever state they're in — and we'll read through them for you. We'll come back with what we found: your properties, your tenants, your rent history, your compliance documents. You tell us what's right, what needs correcting, and what to ignore. Then you're done.
Your files are encrypted in transit and at rest, stored in UK data centres. Everything you upload stays in your account until you choose to remove it — your documents are yours. We extract the structured information we need and don't share raw content with third parties. Everything is handled to the same security standards as the rest of the platform.
MTD enforcement starts April. Section 21 abolition hits May. We're building Harthing now — and early access users get 12 months' free when pricing goes live. No newsletter. No content roundup. Just an invite when it's ready, and a say in what gets built.
We'll email you when it's ready. That's it.
