Boiler Service, Gas Safety Check, Homebuyer Report, Landlord Gas Certificate

Gas Safety Checks, Boiler Servicing, Landlord Gas Certificates & Homebuyer Reports: What’s the Difference?

July 10, 2026

Many homeowners and landlords assume a boiler service, a gas safety check and a landlord gas certificate are all the same thing. They aren’t.

Each inspection has a different purpose, and choosing the right one could help keep your family safe, protect your investment and ensure you remain legally compliant.

In this guide, we’ll explain the differences, who needs each service and when you should arrange one.

Our Commitment to You

Honouring a Legacy: We’ve entered this new phase after taking over ACS Plumbing & Heating. We take our responsibility to honour the memory of Simon Newton very seriously, treating every customer with the care Simon was known for.

Renewable Future: We are fully committed to renewable technologies like air source heat pumps. We believe they will play an increasingly important role in the future of home heating.

Honest, Expert Advice: Not every property is ready for a heat pump yet. We feel a responsibility to give you honest, informed guidance on what’s best for your specific home.

Boiler Service

What is a boiler service?

A boiler service is a preventative maintenance inspection designed to keep your boiler operating safely, efficiently and reliably. During a boiler service, a Gas Safe engineer will inspect, clean and test the appliance, checking for signs of wear, leaks or developing faults before they become expensive repairs.

A typical boiler service includes:

Safety checks and flue inspection
Burner and heat exchanger inspection
Condensate trap cleaning (where applicable)
Expansion vessel pressure check
Gas pressure testing and combustion analysis
Boiler controls and general performance testing

Who needs a boiler service?

Every homeowner should have their boiler serviced once every 12 months. Annual servicing helps improve reliability, reduce the risk of breakdowns, maintain manufacturer warranties, improve efficiency and extend the life of your boiler.

Gas Safety Check

What is a gas safety check?

A gas safety check focuses on safety, rather than maintenance. During the inspection, a Gas Safe engineer checks that gas appliances are operating safely and that there are no dangerous gas leaks or combustion issues.

A gas safety check typically includes appliance safety inspections, gas tightness tests, flue safety, ventilation checks and combustion safety. Unlike a boiler service, the appliance is not dismantled or cleaned.

Which Service Do I Need?

Annual maintenance: Boiler Service

Homeowner safety check: Gas Safety Check

Rental property: Landlord Gas Safety Certificate (CP12)

Buying a property: Homebuyer Gas & Heating Inspection

Landlord Gas Safety Certificate (CP12)

Is a landlord gas safety certificate the same as a gas safety check?

Almost. A Landlord Gas Safety Certificate (CP12) is the official record produced following a landlord gas safety inspection. By law, landlords must arrange a gas safety inspection every 12 months for all gas appliances and flues they provide for tenants.

Homebuyer Gas & Heating Inspection

Buying a home?

Many buyers rely solely on a standard property survey. While surveys are excellent for identifying structural concerns, they rarely provide a detailed assessment of the heating system.

A dedicated gas and heating inspection can identify the age and condition of the boiler, safety concerns, hidden faults and potential repair costs. This provides valuable information before exchanging contracts and can even support price negotiations.
