Landlord Gas Safety Certificate (CP12) Costs [And Your Responsibilities]

Welcome to our 5-minute guide to landlord gas safety certificate costs. In the trade, this is also known as a CP12. But, that’s an outdated description, as that was its label when the governing body for gas work was CORGI, not Gas Safe. The original landlord gas safety certificate was called a CORGI Proforma 12 (hence, CP12).

This guide covers everything you need to know about landlord gas safety certificates including costs, what should be included, how often you need one, and what to do when a tenant refuses access.

How Much Does A Landlord Gas Safety Certificate Cost?

Expect to pay around £60 for a landlord gas safety certificate. This price would include one appliance (i.e. a gas boiler). The cost of the certificate will rise for each additional gas appliance in the property (a gas fire or hob, for instance).

Are There Discounts Available For Multiple Properties?

If you own a property portfolio, or run a letting agent, it’s likely you’ll be able to negotiate a better rate. Expect to negotiate a deal between 10-20% of the single property cost, for 10+ properties annually.

How Much Do Additional Appliance Checks Cost?

Expect to add around 30% for each additional appliance that needs to be included in your landlord gas safety check. So, that would be approximately £60 for a boiler, £78 for a boiler and hob, and roughly £96 for a boiler, hob and gas fire.

Do National Companies Cost More Than Local Installers?

£60 is just a ball park figure. A local installer is likely to charge in the region of £40-65 for a single appliance.

When looking at getting landlord gas safety certificates from National boiler installation companies, the price is likely to spiral quickly. A standard check for a single gas boiler could be as much as £80, with a 3 appliance check and certificate costing in the £120-130 range.

Which Appliances Need To Be Checked?

If you’re a landlord or letting agent, ALL gas appliances need to be checked and included in the gas safety certificate. This isn’t a recommendation, this is a legality.

Gas Safety Checks

So, what should you expect from your gas safety check?

  1. Correct adjustment and combustion of gas
  2. Suitable installation area
  3. Secure installation (for wall-hung units) and pipework
  4. Airflow is free of blockages and sufficient for the room the appliance is installed in
  5. Flue and chimney checks

Your gas safety check won’t include any servicing or repairs. If there’s a problem with any appliance, or any pipework feeding that appliance, this needs to be rectified. And, the engineer will rectify any issues, but at an additional cost to the CP12.

Do You Need To Use A Boiler Manufacturer’s Servicing Team?

Although the likes of Worcester Bosch, Vaillant, Baxi and Ideal have their own boiler servicing teams that can complete a landlord gas certificate, it’s not a legality that you use one of their team.

All you need to ensure, is that the boiler engineer you are using, is qualified to work on gas appliances, and registered with Gas Safe. If you’ve had a quote from a company for any gas work, you can check out their credentials on the Gas Safe Register by searching their Gas Safe number, or company name.

How Often Do You LEGALLY Need To Have A Gas Safety Certificate?

You’ll need to ensure that you have a gas safety check on any tenanted property every 12 months. After 12 months, any previous gas safety check becomes invalid.

And, there’s a big problem that many landlords face. What happens if your Gas Safety certificate is about to expire, but your tenant won’t give you access to the property?

What Happens If A Tenant Won’t Allow Access For A Gas Safety Check?

Always plan for a gas safety check, well in advance of it’s due date. You’re required by law to have a certificate produced every year, but that doesn’t give you automatic access to your property if your tenant refuses.

If you suspect a problem tenant, the first thing to do is speak to a solicitor. According to the Gas Safe register, you can’t force entry, but you’ll need to prove that you have multiple documented attempts to gain access to the property (3 times as a minimum), 10-12 months before the gas safety certificate is due.

If My Tenant Installs Gas Appliances, Am I Responsible?

You are not responsible for gas safety checks on gas appliances, flues or chimneys that are fitted by your tenant or to their appliances.

“Landlords are not responsible for safety checks on gas appliances owned by the tenant or any flues that solely connects to tenants own gas appliances.” – Gas Safe Register

Do You Need A Gas Safety Certificate When Selling/Buying A Flat Or House?

By law, homeowners are NOT required to provide a gas safety certificate to the new owner. So as a buyer, you’ll not know whether the property is gas safe, until it’s checked.

However, most sellers are prepared to organise a Gas Safety certificate, assuming that the buyer foots the bill. Given these certificates cost around £60 and could highlight problems with a heating system that could cost £4,000 to replace, it’s worth the money.
