CalmLet is the UK's simplest landlord compliance app. Track certificates, manage tenants, stay on top of the law — without the spreadsheet chaos.
Sound familiar?
Landlording in 2026 is complicated
New legislation, rising compliance demands and mountains of paperwork. CalmLet was built to take all of that off your plate.
Missed certificate expiries
A lapsed Gas Safety certificate isn't just a fine — it can invalidate your notice to quit and expose you to prosecution. One missed date can cost thousands.
The Renters' Rights Act 2025
In force from 1 May 2026, the new Act requires landlords to serve a mandatory information sheet and comply with new prescribed documentation requirements.
Making Tax Digital headaches
From April 2026, landlords with income over £50,000 must file quarterly digital returns. Spreadsheets and shoeboxes of receipts won't cut it anymore.
Documents scattered everywhere
Gas certs in email, EICRs in a drawer, tenancy agreements on a USB stick. When a tenant asks for their documents, how long does it take to find them?
Juggling multiple tenants
Deposit protection, tenancy start dates, rent reviews, end-of-tenancy notices. Keeping track across multiple properties is a full-time job without the right tools.
Maintenance falling through the cracks
Repair requests, inspection schedules, contractor follow-ups — without a proper system, things slip. Uncompleted maintenance can become costly legal liability.
Everything you need
One app. Total control.
CalmLet brings together every tool a UK landlord needs — without the complexity of enterprise property software.
Certificate tracking & expiry alerts
Track Gas Safety (CP12), EICR, EPC, PAT testing, Legionella, Fire Safety and more. Get notified before certificates expire so you're never caught out.
Property & compliance health
See the compliance status of every property at a glance. Instant colour-coded health indicators show exactly where action is needed.
Tenant management
Store tenant contacts, tenancy dates, deposit details and DPS references in one place. Track right-to-rent checks and manage end-of-tenancy workflows.
Document compliance checklist
The Renters' Rights Act 2025 requires 8 prescribed documents per tenancy. CalmLet tracks which have been sent and acknowledged by each tenant.
Making Tax Digital (MTD ITSA)
Log rental income and allowable expenses, categorised for HMRC. Track quarterly obligations and prepare for your digital Self Assessment filing.
Task & maintenance tracking
Create tasks for repairs, inspections, contractor visits and admin. Due-date reminders keep your maintenance schedule on track and documented.
Send documents to tenants
Generate professional, pre-populated email templates for sending any certificate directly to your tenant. Record when it was sent and acknowledged.
Contractor contacts
Keep a directory of plumbers, electricians, gas engineers and letting agents. Store registration numbers and quickly find who you need.
Email notifications
Set up to 5 email addresses to receive expiry reminders and alerts. Stay informed even when you're not logged in — perfect for agents managing on your behalf.
