Answers you can trust on the job
The AI assistant built for UK gas engineers. It runs the gas calcs to British Standards, cites its sources from real manuals — and flags what's safety-critical. So you get answers you can check, not a general chatbot's guess.
40+ specialist gas tools and direct access to ingested manufacturer manuals — capabilities a general AI chatbot simply doesn't have.
What you get
Everything an engineer reaches for on site — diagnosis, calculations, parts and compliance — in one place, and every answer backed by a source you can check.
Describe a fault in text, photo or video and get step-by-step, source-cited guidance pulled straight from manufacturer manuals and UK gas standards — not a chatbot guess.
15+ built-in calculators — gas rate & pipe sizing (BS 6891), ventilation & flue (BS 5440), combustion (BS 6798), heat loss, LPG and commercial — to current British Standards.
Snap a photo, scan a barcode or just describe it — ToolBench identifies the part, gives you the number and compatible alternatives, and takes you straight to it on Toolstation or Screwfix.
Safety-critical questions get flagged automatically, and you can work through CP12/LGSR, RIDDOR and customer-notice widgets right inside the chat — with the standard referenced on every result.
How it works
No training, no manual. If you can send a text, you can use ToolBench.
Type the problem, or snap a photo or short video of the appliance, fault display or wiring. No special format, no menus — just describe what you’re seeing.
ToolBench pulls the answer from manufacturer manuals and current UK gas standards, and shows you the source it used — so you can check it, not just trust it.
Confirm against the citation, run any calculations or compliance checks you need, and crack on. ToolBench flags safety-critical points so nothing gets missed.
Pricing
Every plan starts with a 14-day trial — 40 credits to try everything. A card is required; you're only charged when the trial converts (after 14 days, or once the 40 credits are used).
Everything a solo gas engineer needs, day to day.
For busy engineers who lean on AI all day.
Shared credits for a team of engineers.
Each action uses credits — chat & calculations 1, parts identification 2, compliance checks 2. Need more? Top up any time with +150 (£5.99) or +400 (£14.99) packs — top-up credits never expire.
FAQ
A general chatbot will confidently invent gas-safety advice, and you have no way to check where it came from. ToolBench has direct access to ingested manufacturer manuals and current UK gas standards, and shows you the source it used on every answer. It also runs 40+ specialist gas tools a chatbot doesn’t have — gas-rate and pipe-sizing calculators, CP12/LGSR, RIDDOR and warning-notice widgets — so you get a checked result, not a paragraph of guesswork. It’s built for one trade, not everything.
ToolBench is a decision-support tool, not a replacement for your professional judgement or your Gas Safe registration. It’s trained on UK regulations and manufacturer documentation and it cites its sources, but you must always verify safety-critical decisions against the latest manufacturer instructions, BS 6891, IGEM standards and current Gas Safe guidance. Responsibility for the work stays with you.
When you mention a make and model — e.g. "Worcester Greenstar 8000" — ToolBench filters its knowledge base to the relevant manuals and specifications and remembers it for the rest of the conversation, so answers stay specific to the kit in front of you.

Every new account starts with a 14-day trial that includes 40 credits so you can try everything. A card is required to start, but you’re not charged during the trial. Your subscription begins automatically when the trial ends — after 14 days, or once the 40 credits are used, whichever comes first — unless you cancel first.
Yes. Cancel in one click from the billing portal. Cancelling stops future renewals and you keep access until the end of the period you’ve already paid for. No phone calls, no retention hoops.
