What is the difference between At Risk and Immediately Dangerous?
Immediately Dangerous (ID) means the appliance poses a danger to life or property if used, while At Risk (AR) means a fault could become dangerous. Both are handled under GIUSP.

Need a Warning for your own property? It's issued by the tradesperson who does the work — TradePlanr is the app they use.
A gas warning or advice notice is issued when an engineer finds an appliance or installation that is unsafe. It records the situation as At Risk (AR) or Immediately Dangerous (ID) and the action taken.
The classification follows the Gas Industry Unsafe Situations Procedure (GIUSP), which sets out how registered engineers should handle and record unsafe gas situations.
TradePlanr lets you complete the warning notice on your phone, record the fault and action, capture the customer's signature, and issue a PDF as evidence.

When it's required
A warning notice is issued whenever an engineer identifies an unsafe gas situation. Immediately Dangerous appliances should be made safe, and At Risk appliances handled according to the procedure, with the customer's permission recorded where needed.
Where a situation is reportable, the engineer should report it under RIDDOR and, where relevant, to the gas emergency service or Gas Safe Register. The notice documents that the customer was warned.
Only a Gas Safe registered engineer should classify and act on unsafe gas situations. The customer signs to confirm they have been advised.

Frequently asked questions
What is GIUSP?
The Gas Industry Unsafe Situations Procedure is the recognised procedure for identifying, classifying and acting on unsafe gas situations.
Do I need the customer's permission to disconnect an appliance?
Yes. An engineer should get the customer's permission to turn off or disconnect an appliance and record that permission on the notice.
When should a gas situation be reported under RIDDOR?
Certain dangerous gas fittings and incidents are reportable under RIDDOR. The engineer should report where the criteria are met and record the details.

Yes. TradePlanr lets you complete the notice on site, capture the customer's signature and send the PDF straight away.
