What Is a Gas Safety Certificate?

A Gas Safety Certificate (often called a CP12) is an official document issued by a Gas Safe registered engineer after inspecting your gas appliances. It confirms that your boiler, hob, oven, gas fire, and central heating system are safe and meet the latest legal standards.

The certificate shows:

  • Each appliance checked and tested.
  • The engineer’s Gas Safe registration details.
  • Confirmation that the installation is safe.
  • Any issues or faults that need attention.

In simple terms — it’s your proof that your gas system is safe, compliant, and ready to use!

Why a Gas Safety Certificate Is So Important

A gas safety certificate isn’t just another bit of paperwork. It’s a legal requirement for landlords and an essential safety check for homeowners. Faulty or poorly maintained gas appliances can cause carbon monoxide leaks, explosions, and even fires.

In London, with its mix of older properties, flats, and shared buildings, gas safety is absolutely vital. Having your appliances checked once a year gives you total peace of mind that your property is safe and compliant.

For Landlords

If you rent out a property, the law (Gas Safety (Installation and Use) Regulations 1998) requires you to:

  • Have a Gas Safe engineer inspect every gas appliance once a year.
  • Provide tenants with a valid Gas Safety Certificate within 28 days of the check.
  • Keep records for at least two years.

Failure to comply can lead to hefty fines, invalid insurance, or even prosecution. We take care of the entire process for you — from scheduling reminders for next year to providing certificates directly to your letting agent or tenant if required.

With Upkeepone, landlords never miss a renewal!

For Homeowners

While homeowners aren’t legally required to have a gas safety certificate, annual checks are strongly recommended. It ensures:

  • Your boiler is working efficiently.
  • No leaks or carbon monoxide issues.
  • You stay covered by your boiler warranty.

A safe home is a happy home – and we’re here to keep it that way!

  4. Flue & Ventilation Checks – We make sure harmful gases are being expelled safely outside.
  5. Reporting – You’ll receive your CP12 Gas Safety Certificate immediately, with clear notes on any issues or recommendations.

If any faults are found, we’ll explain them clearly and offer a repair or quote on the spot. Our goal is always to keep you safe, not to surprise you with hidden costs.

FAQs

A gas safety certificate is valid for 12 months from the date it’s issued. You’ll need to book a new inspection each year to stay legally compliant. Many London landlords arrange the next check a few weeks before the current one expires to avoid any gap in cover.

Yes! Many local Gas Safe engineers in London, including Upkeepone, offer same-day or next-day gas certificates. If you’ve got tenants moving in soon or need urgent proof for your letting agent, a quick call usually gets it sorted within hours.

While it’s not a legal requirement for homeowners, getting a gas safety certificate in London is highly recommended. It helps prevent dangerous leaks, improves efficiency, and keeps your boiler warranty valid. Think of it as an annual health check for your home’s gas system.

They’re exactly the same thing! The term “CP12” comes from the old CORGI registration days, before Gas Safe Register replaced it in 2009. Today, engineers issue the same type of document – it just confirms your appliances have passed their annual safety checks.

Always ask to see their Gas Safe ID card before they start work. You can also visit the official Gas Safe Register website and search for their licence number. This ensures your engineer is qualified to issue gas certificates legally and safely.

The price varies by area and number of appliances, but on average, a gas safety certificate in London costs between £75 and £100. Some companies offer combined boiler service and CP12 packages at discounted rates – perfect for landlords managing multiple properties.

You’ll receive a digital or paper gas safety certificate (CP12) listing each appliance, its test results, and the engineer’s Gas Safe details. It acts as official proof that your property meets all current gas safety standards.

Absolutely! Many London engineers, including Upkeepone, provide flexible appointment times, including evenings and weekends. It’s especially handy for busy landlords or tenants who can’t take time off work.

If an appliance is found unsafe, the engineer will explain the issue clearly and may label it as “At Risk” or “Immediately Dangerous.” You’ll get clear guidance on what to repair or replace before a valid certificate can be issued. Once fixed, a retest can be arranged quickly.

Yes, letting agents across London can book gas safety inspections directly with approved engineers. At Upkeepone, we often work with estate agents and property managers, sending certificates straight to both landlord and tenant once complete.

It’s not legally required, but it’s strongly recommended. Buyers often ask for recent gas safety records to confirm the property’s systems are safe and well-maintained. It adds confidence and can help smooth the sales process.

Yes – each self-contained unit with its own gas supply or appliances requires an individual certificate. If you manage multiple flats in London, you can save time (and money) by booking them all together with the same registered engineer.

A commercial gas safety certificate covers larger systems such as those in restaurants, offices, and shops. Engineers check pipework, boilers, catering equipment, and ventilation systems to ensure everything meets commercial Gas Safe regulations.

Yes – look at the expiry date on your current CP12 certificate. It’s valid for exactly 12 months from the inspection date. If you’re unsure, contact your previous engineer or call our team at Upkeepone, and we’ll confirm your renewal date instantly.

Make sure all gas appliances are accessible and any cupboard doors around boilers are cleared. Have your Gas Safe ID ready for verification if you’re using a new engineer. The inspection usually takes less than an hour, so it’s a quick and simple process!

Yes! As long as the certificate is still valid (within 12 months), it remains valid for the property, not the tenant. You can simply provide the same certificate to your new tenants to prove the home is gas safe.

Yes – under recent housing regulations, landlords must fit carbon monoxide alarms in any room with a gas appliance (excluding cookers). They’re a vital safety measure alongside your annual gas safety certificate.

Simply call your local Gas Safe engineer or book online with Upkeepone. We cover all London postcodes, from Zone 1 to Zone 6, and often provide same-day certificates for urgent landlord or tenant requests.

Not by default – a gas safety check only verifies safety and compliance, while a boiler service involves cleaning and performance testing. However, many London companies (including us) offer combined packages to save you time and money.

Tenants can’t legally arrange the official landlord’s gas safety certificate, but they can book a private inspection for peace of mind. It’s a good idea if you suspect issues like unusual smells, yellow flames, or poor heating performance.
