Best Landlord Compliance Software UK 2026

A landlord's compliance is unforgiving and deadline-driven: a lapsed gas certificate, an unprotected deposit or a missing Right to Rent check can mean fines, an invalid Section 21, or worse. This guide is about what landlord compliance software needs to do, and how the options compare — for landlords managing their own properties. It sits under the broader best property compliance software guide, and the whole-market best compliance software in the UK.

What landlords need from compliance software

Safety certificates

Gas (CP12), EICR, EPC and PAT tracked per property with renewal reminders — the legal backbone of letting, and the easiest thing to let slip.

certificate tracking →

Deposits & Right to Rent

Deposit protection within the deadline and Right to Rent checks recorded per tenancy — the paperwork that voids a Section 21 if missed.

lettings management →

Licensing

Mandatory, additional and selective licensing tracked per property, so you know which need a licence and when each is due.

landlord compliance software →

Fire & CO safety

Smoke and CO alarm records, and fire risk assessments where required — increasingly scrutinised in the private rented sector.

fire safety →

Contractor dispatch

Send renewals to vetted, insured engineers and keep their certificates in date, so an out-of-date contractor is blocked from the job.

contractor records →

Portfolio compliance score

One view across every property showing what's compliant, what's expiring and what's overdue — instead of a folder per property.

Which landlord compliance software is best?

Best all-in-one for landlords

Best for whole lettings operations

Property-management suites (e.g. Arthur, Reapit)

Full lettings and property-management software covering rent, tenancies and accounts; strong on the operation, less focused on compliance evidence specifically.

Best for accidental / small landlords

Complys free & low tiers

One or two properties can start on a free or low tier — certificate tracking and reminders without a full management suite.

Landlord compliance software — FAQs

What is the best landlord compliance software in the UK?

For landlords who want gas, EICR, EPC and fire certificates, deposits, Right to Rent and licensing tracked across a portfolio with renewal reminders and a compliance score, an all-in-one landlord platform like Complys is the strongest fit. Full property-management suites like Arthur or Reapit are stronger on rent and tenancy operations but less focused on compliance evidence. The best choice depends on whether your priority is compliance or the whole lettings operation.

What compliance do landlords legally need to track?

The core recurring items are the annual Gas Safety Record (CP12), a valid EICR (electrical, typically five-yearly), an EPC, and working smoke and CO alarms. Depending on the property you may also need a licence (mandatory, additional or selective) and a fire risk assessment. Deposits must be protected within the statutory deadline and Right to Rent checks recorded — miss those and a Section 21 can be invalid. Software keeps all of these current across the portfolio.

Does landlord compliance software send renewal reminders?

Yes — that's its core value over a spreadsheet. It records each certificate's renewal date per property and reminds you (and can dispatch a vetted engineer) before it expires, so a lapsed gas or electrical certificate is flagged rather than discovered when a tenant complains or a claim arises. Reminders are what turn a list of dates into actual protection.

Is there landlord compliance software for a small portfolio?

Yes. You don't need a full property-management suite for one or two properties — certificate tracking with reminders is the essential, and platforms like Complys offer a free trial and low tiers so a small or accidental landlord can stay compliant affordably. As the portfolio grows, the same platform scales to licensing, contractor management and a portfolio compliance score.

What's the difference between landlord and letting agent compliance software?

Landlord software manages compliance for a landlord's own portfolio. Letting agent software manages compliance on behalf of many landlords across a managed portfolio, with agent-specific needs like landlord reporting and handling multiple clients' properties. The underlying compliance is similar; the difference is who's accountable and how many parties are involved. See the best letting agent compliance software if you manage properties for others.
