Boiler Service vs Gas Safety Check: What’s the Difference and Which Do You Need?
Whether is it a Gas Safety Check or a Boiler Service, we offer the services you need, when you need them.
At Central Plumbing & Heating, we’re often asked the same question:
“Do I need a boiler service, or a gas safety check?” The answer depends on whether you're a homeowner or a landlord, usually.
Here’s a clear breakdown to help you make the right choice.
What Is a Boiler Service?
A boiler service is a routine inspection and maintenance process carried out by a qualified Gas Safe engineer. The aim? To keep your boiler working safely, efficiently, and reliably all year round.
A full boiler service includes:
• A visual inspection of the boiler and flue
• Internal testing of components (burner, heat exchanger, etc.)
• Cleaning of components if necessary (burner, heat exchanger, etc.)
• Checking pressure, seals, safety devices, and controls
• Testing gas pressure and flow
• Identifying wear, faults, or signs of breakdown
Why it matters:
• Safety
• Helps prevent costly breakdowns
• Keeps heating bills lower by maintaining efficiency
• Extends the life of your boiler
• Validates manufacturer warranties (if serviced annually)
• Provides peace of mind for your home or business
Recommended: Annually for all homeowners and business properties
What Is a Gas Safety Check?
A gas safety check (also known as a CP12 or a Landlord gas safety check) is a legally required annual inspection for rental properties. It ensures that all gas appliances — not just the boiler — are operating safely and comply with UK regulations.
A gas safety check includes:
• Inspection of all gas appliances (boilers, cookers, fires)
• Ensuring appliances are correctly set and burning safely
• Checking ventilation and air supply
• Testing for leaks or pressure issues
• Issuing a Gas Safety Certificate (CP12) for landlords
Why it matters:
• Required by law for all landlords (annually)
• Ensures tenant safety
• Avoids fines or legal penalties
• Highlights potential issues before they become serious
• Shows your duty of care is being met
Mandatory: Annually for landlords or managing agents
Did you know? A gas safety check can be booked up to 8 weeks in advance without changing the renewal date.
Do I Need Both?
If you’re a landlord, yes — you should arrange both. A gas safety check ensures legal compliance, but a boiler service goes deeper into the performance and condition of the boiler itself.
If you’re a homeowner, a boiler service is usually enough — but if you have multiple gas appliances or concerns about safety, a full safety check can offer additional reassurance.
