Flow Pack terms of use
Updated 12-11-2026. Plain words.
Flow Pack is provided by Nero Engine Group Ltd (company 16521432, England and Wales), trading as Nero Labs. By connecting it to your AI app you agree to these terms.
What it is
Free tools a UK plumber's or heating engineer's AI assistant uses on the job: water and gas pipe sizing, room by room heat loss with boiler, heat pump and radiator sizes, notifiable work rules, gas safety record checks and emergency triage. It is a tool your AI assistant calls. It does not replace a qualified person's judgement.
Cost
Free. There is no paid plan and no card is ever asked for.
Your responsibility
- Answers are worked out from what you or your AI send. Check them before you rely on them, and check anything the answer says must be confirmed (maker's data, the regulations, building control, HMRC).
- The trade doing the work stays responsible for the work, its safety, its compliance and the prices and paperwork they issue.
- Only send details you are allowed to share, and only for your own business.
Fair use
- Do not try to break, overload or copy the service, get round its limits, or use it to harm or mislead anyone.
- We may block traffic that does, and we may change, pause or stop the service. We will keep this page up to date.
Our liability
The service is given as it is, without a guarantee that it is always right or always available. As far as the law allows, we are not liable for indirect loss or loss of profit, and our total liability is limited to £100. Nothing here limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, or your rights as a consumer.
Privacy and law
How data is handled is on the privacy page. These terms are governed by the law of England and Wales. Questions: founder@neroengine.com.
