A Guide for Homeowners & Landlords in Surrey & London

---

If you own or manage a property in the UK — especially in areas like Kingston, Richmond, or across Surrey and London — you’ve probably heard of the Gas Safety Certificate (also known as a CP12). But what exactly does it cover, and why is it so important?

At Certificates4UK Ltd, we’ve completed thousands of gas safety inspections. In this guide, we’ll clearly explain what’s included in a Gas Safe Certificate, why it matters, and how it protects both your property and your people.

What Is a Gas Safe Certificate (CP12)?

A Gas Safe Certificate is an official document issued after a registered Gas Safe engineer inspects your property’s gas appliances and pipework. It’s a legal requirement for landlords and a highly recommended safety measure for homeowners.

---

What Does a Gas Safe Certificate Include?

Here’s what you can expect during a professional inspection:

---

1. Appliance Checks

Each gas appliance (boiler, cooker, fire) is checked for:

• Gas tightness (ensuring there are no leaks)
• Correct burner pressure and gas rate
• Adequate ventilation and proper flue flow
• Safe ignition and shutdown operation
• Functional flame failure devices

In short, we ensure each appliance is running safely and efficiently.

---

2. Safety Devices & Controls

Next, all safety devices are tested to ensure they’re working properly. This is crucial in preventing carbon monoxide leaks and other hidden dangers.

---

3. Flue Inspection

Flues and chimneys are checked for:

• Blockages
• Secure connections
• Proper expulsion of combustion gases

Why it matters: Poor flue performance can trap dangerous gases inside the home.

---

4. Gas Pipework Condition

We examine visible gas pipework for:

• Corrosion or wear
• Leaks
• Signs of tampering or unsafe installation

Any serious issues are flagged immediately.

---

5. Emergency Shut-Off Valves

We also check your emergency gas shut-off valves to make sure they are:

• Clearly labeled
• Fully functional
• Easily accessible

---

After your inspection, you’ll receive a report containing:

🧾 Certificate Includes	🔎 Description
Property address	Location of inspection

Engineer’s name & Gas Safe number	Proof of registration

Landlords: Your Legal Responsibility

If you’re renting out a property, the law requires you to:

• Conduct a Gas Safety Check every 12 months
• Provide your tenant with a copy of the CP12 within 28 days
• Keep records of inspections for at least 2 years

Failure to comply may result in:

• Legal fines
• Invalidated insurance
• Criminal prosecution
• Risks to tenant safety

At Certificates4UK Ltd, we work with landlords and letting agents across Surrey and London to ensure full compliance.
