AI boiler triage that knows itslimits — and a Gas Safe engineer’s number.
BoilerBuddy is the missing first step between “the radiators are cold and the boiler is making a noise” and “I need someone qualified to look at this.” Plain-English triage for UK homeowners. Honest about when to stop and call a registered engineer.

How a triage works
A short, picture-led conversation with a clear next step.
BoilerBuddy doesn’t try to be your engineer. It tries to be the calm, useful first response — and gives you the right off-ramp when the situation is past the “safe to try at home” line.
Tell us what your boiler is doing
Describe the symptom in your own words or point your phone at the fault code. Plain English is fine — there’s no jargon to learn.
BoilerBuddy walks you through triage
Pressure top-ups, thermostat resets, what to look for by sight or sound, and the safe-to-try-at-home checks first suggested by Worcester Bosch, Vaillant, Baxi and Ideal.
A clear handoff if it’s not safe to wait
If the answer is “call a registered engineer”, BoilerBuddy says so plainly — with two Gas Safe engineers near you and a one-tap way to put you in touch. We never guess or improvise around the gas regs.
What BoilerBuddy covers
The boiler problems your boiler actually has.
Built around the faults and error codes we see most across the UK stock — and the manufacturers whose manuals everyone has, but nobody reads cover-to-end.
Brands we recognise
Fault families we’ll walk you through
- Error codes & lockouts
- Low boiler pressure
- No heating / no hot water
- Pilot-light issues
- Kettling & strange noises
- Leaks & drips
- Thermostat faults
- Frozen condensate pipe
Save once, tune every triage
Save your boiler profile once and we’ll tune each triage to it.
Pick your make, model and age band — BoilerBuddy pre-fills them on every triage, and shifts the “try this at home” tone for older boilers.
Where BoilerBuddy stops
When the situation tips into an emergency, BoilerBuddy hands off — it doesn’t improvise.
UK law reserves appliance work for Gas Safe registered engineers. BoilerBuddy is the conversation before that step — not a workaround. The four triggers below short-circuit any other advice and route you straight to a qualified person.

The handoff
“Call a registered engineer” — and here are two near you.
Serious findings end with a clear next step, not a generic disclaimer. When the answer is “this one is for a Gas Safe engineer”, BoilerBuddy lists two nearby options and a single tap to put you in touch via our dispatch partner network.
Where BoilerBuddy sits
The homeowner end of the funnel — not a rival to your engineer.
Tools like Gas App UK’s Boiler Bot, XSol, Your Gas Fault App, OxMaint and Psiktikos are built for engineers holding the wrench — they carry liability and assume a trained reader. BoilerBuddy is calibrated for the moment before that — when the homeowner is the one holding the phone, deciding whether to top up the pressure or pick up the phone to call someone.
Built for the call before the call
Designed around the homeowner moment — worried, on the sofa, trying to decide if they need help.
Honesty as the headline feature
When the answer is “don’t do this yourself,” BoilerBuddy says so without hedging or upsell.
Protects the engineer relationship
Routes serious work to engineers, never past them. We don’t replace the wrench — we’re the conversation before it.
