The app itself does not include a chatbot or generate answers while you use it. Gas Safe registration belongs to individual engineers, not apps. BoilerFix AI is an independent tool and is not affiliated with or endorsed by Gas Safe Register, OFTEC or any boiler manufacturer.

Flint is the onsite guide for UK gas engineers. The manufacturer's manual, the fault codes, the service figures and the fault-finding chart for 2,300+ domestic gas boilers, in your pocket and ready before you've unclipped the case. FIND IT FAST • 2,300+ gas boilers across 45 manufacturers, one page per boiler. Search by make and model, by the maker's own code, or by the GC number off the badge: Flint names the appliance from the official product register and checks the manual really covers your number • 60,000+ fault codes: what it means, the likely cause, and the parts that usually get changed. Every code traced to the manual it came from • 1,000+ manufacturers' manuals with full-text search, so you land on the page instead of thumbing through ninety of them • Service figures for 2,100+ models: combustion targets at max and min rate with the maker's tolerance band, gas pressures, service mode, gas valve settings, sensor tables. Every figure cites the manual page it came from, and every wiring table, service-mode procedure and combustion figure has been read back against that page FAULT-FINDING CHARTS Older boilers have no fault codes; the manual gives a flowchart. Flint walks it with you, one box at a time: the question, Yes or No, the next box, into the LED table where the chart hands over, and on to the section it sends you to. 1,100+ boilers, with the manual page always one tap away. ASK FLINT Type a question in plain English and get an answer built from that boiler's own manual, with the page cited so you can check it. It reads the manual faster than you can. It doesn't decide, it doesn't sign anything off, and it won't go past what the manufacturer printed. You're the engineer. Flint just fetches. TOOLS • Gas rate, with a built-in stopwatch, metric and imperial • Tightness test with the let-by and stabilisation timers, and the permitted drop for your meter • CO/CO₂ ratio against the 0.004 limit • Temperature rise (ΔT) and expansion vessel sizing • Boiler age from the serial number, decoded from the maker's own scheme and showing its arithmetic so you can check it • Unsafe situations: tap through what you've found and get the IGEM/G/11 classification, ID, AR or NCS, with the action that goes with it. A paraphrased summary written for speed on site, not the standard itself, and no substitute for your judgement • Every manufacturer's UK technical helpline, tap to call BUILT FOR THE VAN, NOT THE OFFICE Dark, glare-friendly screen. Big, tappable controls. Made for standing at the boiler, not sitting at a desk.
