The BoilerBuddy approach
A safer, simpler way to deal with boiler problems.
Start with the facts you can see, follow the safe checks that fit, and get a clear handoff when the situation belongs with a qualified engineer.
- Safety-first guidance puts gas and carbon monoxide concerns ahead of troubleshooting.
- Clear next steps help you move forward without guessing at a diagnosis.
- Engineer-required boundaries make it obvious when a Gas Safe registered engineer should take over.
- When a genuinely safe homeowner check can resolve the issue, we help you avoid an unnecessary call-out.
BoilerBuddy supports your decision — it does not replace a Gas Safe registered engineer.
