What Is a CP12 Gas Safety Certificate?
A CP12, often called a Landlord Gas Safety Record, confirms that a gas safety check has been carried out on relevant gas appliances and flues. It is especially important for rented homes, managed properties and landlord portfolios.
It is not just a piece of paperwork. It helps show that gas appliances have been checked by a qualified person and that any visible safety issues have been recorded.

What Does the Engineer Check?
During a CP12 appointment, the engineer checks the visible condition and safe operation of relevant gas appliances. This can include a boiler, gas cooker, hob, gas fire, flue, ventilation and gas tightness where required.
The aim is to confirm whether the appliances are operating safely at the time of inspection and whether any defects need attention.
🧰
What Should Landlords Prepare Before Booking?
Before booking, prepare the property address, tenant contact details, appliance list, parking or access notes, and any known issues such as boiler fault codes, low pressure, unusual smells or previous failed checks.
If the property is tenanted, arrange access early. Missed appointments can delay certification and may create unnecessary stress near renewal dates.

How Appliance Numbers Affect the Booking
The number of gas appliances matters because a property with one boiler is quicker to check than a property with a boiler, hob, gas fire and additional appliances. This can affect appointment time and pricing.
Before confirming, check Gas Safety & CP12 Certificate Pricing so you choose the right option for the property.
⚠️
Common Issues Found During CP12 Checks
Common findings include poor appliance condition, blocked or unsafe flues, ventilation issues, pressure problems, failed combustion readings, unsafe installations or appliances that require further repair.
If a problem is found, the engineer should explain the issue clearly and advise whether repair, servicing or further investigation is needed.
