The most common compliance mistakes letting agents make (and how to avoid them)

Letting agent compliance has never carried higher stakes. Since the Renters' Rights Act 2025 came into force, local authorities can issue civil penalties of up to £7,000 for minor breaches and up to £40,000 for serious or repeat non-compliance. Tenants can pursue rent repayment orders worth up to two years' rent. And crucially, acting on behalf of a landlord does not shield an agent from liability. If the rules are breached on your watch, you can be fined alongside your client.

Here's the uncomfortable truth: most compliance failures in the private rented sector aren't caused by rogue operators cutting corners. They're caused by good agents managing hundreds of properties with spreadsheets, inboxes and memory. A certificate expires quietly. A document gets saved in the wrong folder. A licensing boundary changes and nobody notices.

In this post we'll walk through the most common compliance mistakes letting agents make, what they actually cost, and why so many agencies are now turning to compliance automation to close the gaps.

This is the big one, and it catches out more agents than anything else on this list.

Every tenanted property in England carries a stack of certificates with their own renewal cycles. Gas safety certificates (CP12) must be renewed every 12 months. Electrical installation condition reports (EICRs) run on a five year cycle. Energy performance certificates (EPCs) last ten years, but a property cannot legally be let with a rating below E. Smoke and carbon monoxide alarm checks, legionella risk assessments, portable appliance testing where applicable: the list keeps growing.

Now multiply that across a portfolio of 150 properties. That's easily 500 or more dates to track, each with different lead times for booking engineers.

The consequences of letting one slip are severe:

• An expired gas safety certificate is a criminal offence under the Gas Safety (Installation and Use) Regulations, carrying unlimited fines
• Failing to meet electrical safety standards now sits in the up to £40,000 penalty band under the Renters' Rights Act
• A missing or invalid certificate can undermine possession proceedings entirely, leaving your landlord client stuck and looking for someone to blame

The pattern is always the same: the certificate didn't fail, the tracking did. A renewal reminder lived in one person's Outlook calendar, that person went on leave, and the date sailed past.

Compliance isn't just about doing the right thing. It's about being able to prove you did the right thing, on the right date, with the right document.

Local authorities now have a statutory duty to investigate breaches, and they need to be satisfied beyond reasonable doubt before issuing a penalty. That cuts both ways. If your records are watertight, you can rebut an allegation quickly. If your evidence is scattered across email threads, shared drives and a filing cabinet in the back office, you're exposed even when you've done nothing wrong.

The most common record keeping failures we see:

• No proof of service for key documents (gas safety certificates, EPCs, the government's prescribed information sheet, deposit prescribed information)
• Documents stored against the wrong property or tenancy
• No audit trail showing when a document was issued, signed or sent
• Departing staff taking institutional knowledge with them, because the "system" was in their head

Under the Renters' Rights Act, failing to give tenants required written terms or legal information is itself a finable breach. Serving a document incorrectly is treated the same as not serving it at all. "We definitely sent it" is not a defence. A timestamped record of exactly what was sent, to whom, and when, is.

Right to Rent remains one of the most misunderstood obligations in lettings, and the penalties for getting it wrong increased sharply in 2024. Civil penalties now run up to £10,000 per occupier for a first breach and up to £20,000 per occupier for repeat breaches.

The mistakes are rarely about skipping the check altogether. They're about doing it almost correctly:

• Checking the lead tenant but not every adult occupier aged 18 or over
• Accepting documents that aren't on the Home Office approved list
• Failing to record the date the check was carried out, which is essential to establishing a statutory excuse
• Missing follow-up checks for tenants with time-limited immigration status
• Using the online checking service but not retaining the share code result

That last category is particularly dangerous. A time-limited Right to Rent check creates a future deadline, and as with certificate expiries, future deadlines are exactly what manual systems lose track of. The initial check gets done diligently at move-in, then the follow-up date disappears into a spreadsheet nobody reopens.

Property licensing is a postcode lottery, and that's precisely what makes it so easy to get wrong.

Mandatory HMO licensing applies nationally to properties with five or more occupants forming two or more households. But additional licensing and selective licensing schemes are set by individual councils, cover different areas, start and end on different dates, and change regularly. A street that needed no licence last year may sit inside a new selective licensing zone today.

For letting agents this creates three recurring failure modes:

• Not realising a property needs a licence at all, especially after a council introduces a new scheme mid-tenancy
• Letting a licence lapse, because renewal dates weren't tracked alongside other compliance deadlines
• Breaching licence conditions, such as occupancy limits or management requirements, without realising the conditions existed

The exposure here is brutal. Failing to obtain a required HMO or selective licence sits in the top penalty band of up to £40,000, alongside the risk of criminal prosecution with unlimited fines and rent repayment orders. An unlicensed property can also leave landlords unable to pursue possession, which means your client's problem quickly becomes your problem.

The newest mistake on this list is also the most current one. The Renters' Rights Act 2025 didn't just abolish Section 21. It introduced a whole layer of new obligations with their own deadlines and penalty regime:

• Serving the prescribed information sheet to tenants, in the correct form, individually to each HMO tenant
• Stating the rent clearly in every advert and avoiding anything that looks like rent bidding
• Following the new possession grounds correctly, because knowingly relying on false grounds carries penalties of up to £40,000
• Respecting the restricted period rules on re-letting after using certain possession grounds, where breaches start at a £25,000 penalty

Agencies that bolted these requirements onto already stretched manual processes are finding the cracks quickly. Every new obligation is another date, another document, another proof-of-service record. The compliance burden didn't grow by ten per cent. It changed shape entirely.

Look back at the five mistakes above and notice what they share. None of them stem from agents not knowing the rules. They stem from systems that depend on people remembering things.

Spreadsheets don't chase engineers. Inboxes don't escalate when a deadline is seven days out. Filing cabinets don't tell you which of your 200 properties has an EICR expiring next month. People are brilliant at relationships, negotiations and judgement calls. They are reliably bad at tracking hundreds of recurring dates without error, and the new enforcement regime punishes exactly that kind of error.

This is why compliance automation has moved from nice-to-have to essential for letting agents and landlords alike. Property compliance software does the unglamorous work that manual systems fail at:

• Tracking every certificate, licence and check across your whole portfolio in one place
• Sending automatic reminders well before deadlines, escalating as they approach
• Keeping a complete, timestamped audit trail of every document, ready if a council ever comes asking
• Flagging gaps the moment a new property is onboarded, rather than at renewal time

We built Landy for exactly this moment in the UK private rented sector. It gives letting agents and landlords a single compliance dashboard covering gas safety, EICRs, EPCs, Right to Rent follow-ups, licensing and the new Renters' Rights Act obligations, with automated reminders and a full audit trail behind every property.

The agents who come through enforcement unscathed over the next few years won't be the ones who worked the hardest. They'll be the ones whose systems never let a date slip in the first place.
