Hi,

As a lot of of you guys have been through the process could someone please clarify something for me.

I've been working on a project since December 2009, initially for my own personal use. The device is mains (240v) powered and drives mains heaters at the same voltage. I've just had a small batch of PCB's made to prove the schematic and I'm in the process of making the prototype. I've had lots of interest from others who have suggested that I make these units available on a small commercial basis. My concern is that whilst I'm confident the device is sound and fit for purpose in my own home (the original prototype has been running for almost three months without a problem) I don't want to be responsible or help liable by any 3rd party in the event of a fire or electrocution.

I gather that any device marketed in the EU needs to be CE approved, and given the fact the previous poster is in the testing / compliance business would like to hear what directives my device should comply with and what the typical cost in getting a mains powered thermostatic device through the testing.

What would be the implications if I sold such a device privately without any CE certification - is that actually legal now ? I personally don't have the funds to meet any £15K fine and don't fancy spending time inside....
