You could do the bit about in house certification for fridge engineers if you wanted as both DASA and Refcom are touting their wares even though like us they have not been approved. If you wanted you could be really naughty and use the f-gas and defra logos like DASA 8) But I know you really like to have the ducks in order first. Seems since my query about stationary systems its died a death – wonder why?? 😀 Whilst I think about it can you let me have my user name and password by pm as I’ve never been able to get on it either :rolls:
