The Boiler & Gas Safety Checklist Every Cramlington Homeowner Needs

Gas work isn't an area where it pays to cut corners or guess — a boiler, gas fire, or cooker that's installed or serviced badly isn't just an inconvenience, it's a genuine safety risk. Northumberland Plumbing and Gas, based in Cramlington, deals with gas safety checks and repairs across Northumberland every week, and there's a fairly consistent set of things worth checking before you book anyone for gas work. Here's your checklist.

Before You Book Anyone

• Check they're Gas Safe registered — not just "qualified" or "experienced." It's a legal requirement for anyone working on gas appliances in the UK.
• Ask for their Gas Safe ID card and check the registration number online if you want extra reassurance.
• Confirm they're registered for your specific job — boilers, cookers, and gas fires are separate categories, and not every engineer covers all three.

Your Annual Boiler Service Checklist

• Book your service annually, ideally before the heating season starts rather than during the first cold snap.
• Ask what's actually included — a proper service checks the flue, safety devices, gas pressure, and signs of corrosion, not just a quick visual look.
• Get a carbon monoxide reading as part of the service — this is one of the most important checks it should include.
• Keep every service record safe. A consistent history matters for warranties and reassures buyers if you ever sell.

Landlords: Your Legal Non-Negotiables

• Renew your Gas Safety Certificate (CP12) every 12 months without exception.
• Give tenants a copy within 28 days of the check.
• Keep your own copy for at least two years.
• Never let a certificate lapse, even briefly — it invalidates your compliance.

Warning Signs You Shouldn't Ignore

• A yellow or orange flame instead of crisp blue on a boiler or hob — a sign of incomplete combustion.
• Soot or dark staining around a gas appliance.
• A carbon monoxide alarm going off — never assume it's a false alarm without getting it checked.
• Unexplained headaches, dizziness, or nausea that ease when you leave the house.

Fit and Test a Carbon Monoxide Alarm

• Install one in any room with a gas appliance, positioned to the manufacturer's guidance.
• Test it monthly using the test button, just like a smoke alarm.
• Replace it before its expiry date — sensors degrade even if the alarm still powers on.

Get Everything in Writing

• Ask for a written quote before work starts, covering parts, labour, and callout charges.
• Request an invoice and any relevant certificates once the job is done.
• Query anything you don't understand before agreeing to the work, not after.
