A Gas Safe engineer can inspect your gas appliances, fittings and chimneys to ensure they meet legal standards and are safe for your tenants. We therefore recommend budgeting at least £80 for this check.
However, do also consider that this price range is typically for a property with one boiler, one gas hob or fireplace to check. Additional gas appliances are typically charged at £10 each.

Factors affecting the cost of a CP12 Certificate
Number of appliances
The number of gas appliances that need to be checked is a key factor affecting the total cost of a Gas Safety Certificate.
While you aren't responsible for any gas appliances the tenant has purchased separately, you are responsible for the pipework that supplies the gas. For that reason, it's best to include all gas appliances in your inspection.
Your location
Your gas inspection must be carried out by a registered Gas Safe engineer, but individuals will charge different rates for their services. This is especially the case for Gas Safe engineers working in London and the south east.
Like most trades, gas safety engineers in and around London are more expensive.
Extra gas safety costs to consider
Keep in mind that any electrical appliances supplied with the property will also need an inspection before tenants move in.
As with gas appliances, a qualified Electricity Safe engineer will need to undertake this statutory check separately, so it's worth factoring this into your budget.
You could save on cost by 'lumping' products together. For instance, use a rental agent who includes the cost of a gas certificate and electrical safety certificate in their management fee. You may even wish to have your boiler serviced at the same time as the gas safety check.
Cost of hiring a Gas Safe engineer vs DIY
A Gas Safety Certificate check isn't a task you can do yourself to save costs. You can only obtain a Gas Safety Certificate if the work is carried out by a registered Gas Safe engineer.
But if you're a first-time landlord and don't have an established black book of contacts, how do you find a trusted and certified Gas Safety engineer near you? That's where Checkatrade can help.

3 steps to finding the right tradesperson for you
1. Know what you need
Before reaching out to tradespeople, take a moment to map out your project. The clearer you are about what you want, the easier it is for them to understand your needs and give you a more accurate quote. Plus, fewer surprises down the line!
2. Do your homework
Finding the right tradesperson is about more than just price, it’s about trust – so a little digging now can go a long way. Here’s how to check if they’re the right fit:
Look online – Check their website and social media to see examples of their work and what their customers are saying
Read reviews – Look at ratings on social media, Trustpilot – and Checkatrade of course! – to see how others rate their work
Ask for references – A great tradesperson will have happy customers who are happy to recommend them
Meet in person – A quick chat can tell you a lot about who you're hiring. Take your time and speak to a few tradespeople before making a decision. It’s worth the effort
3. Use Checkatrade for extra peace of mind
Even if you find a tradesperson elsewhere, running a quick Checkatrade search can boost that ‘yep, I’ve nailed it’ feeling. Our tradespeople must pass up to 12 checks before we list them, and score an average of 9/10 based on reliability, workmanship and tidiness.
