✅ Three Ways to Use This Tool
1. Create a new Gas Safety Log: Ensure you capture all mandatory information for legal compliance and audit trails

⚠️ What Makes a Valid UK Gas Safety Certificate Log?
🔥 Legal Requirement: Annual gas safety checks are mandatory under Gas Safety (Installation and Use) Regulations 1998. Landlords must maintain records proving compliance.
⚖️ Criminal Liability: Failing to conduct annual checks or maintain proper records is a criminal offence. Penalties include unlimited fines and up to 6 months imprisonment.
🎯 Essential Elements: Property details, certificate number and dates, Gas Safe engineer verification, appliance inspection records, tenant notification proof, renewal scheduling.
💼 Common Issues: No tracking system, missing engineer Gas Safe numbers, no tenant notification records, certificates expiring without renewal, incomplete appliance details.
🚫 Critical Legal Requirements
Annual Checks: Gas safety inspections MUST be conducted every 12 months by Gas Safe registered engineers. 28-Day Rule: Existing tenants must receive a copy of the certificate within 28 days. New tenants must receive it before moving in. Gas Safe Registration: Only Gas Safe registered engineers can conduct landlord gas safety checks. Always verify registration. Insurance: Invalid or expired certificates may void landlord insurance claims for gas-related incidents.

Record the exact date you provided the certificate to the tenant. Must be within 28 days of the inspection date. This date is your proof of compliance if challenged by the tenant or HSE.
🔴 Critical
Method of Delivery
How you provided the certificate: email, hand delivery, post. Email is recommended as it creates an automatic timestamp. If posted, use signed-for delivery for proof.
🟡 Important
Proof of Delivery
Keep evidence you provided the certificate: email send confirmation, tenant's signed receipt, postal tracking number. Essential if tenant later claims they didn't receive it or HSE investigates.
🔴 Critical
New Tenant Pre-Occupancy Check
For new tenancies, confirm the tenant received the gas safety certificate before they moved in and before signing the tenancy agreement. A critical legal requirement that's often missed.

🟡 Important

🟡 Important
Engineer Pre-Booked
Confirm whether next year's check is already scheduled. Many landlords book engineers annually to secure preferred dates and rates. Record booking confirmation and appointment date.
🔵 Recommended
Tenant Access Arranged
For next year's check, confirm how you'll arrange tenant access. Record whether tenant has agreed to annual inspections, preferred contact method, and any access issues from previous years.

🔴 Critical
Dangerous Appliances Disconnected
