It may be better; or even worse.
As someone who generally designs and manufactures one or two items per contract, the whole CE regime has been a costly problem. The main reason is not the CE legislation in itself but the way UK civil servants gold plate them.
A good example of this is the WEEE directive. In the beginning it was costing me over £600 per year to register with a UK Producer company. In Europe, small companies registered directly with their Government agencies. After one of No 10's red-tape campaigns this was changed based on the weight on manufactured per year (at best 80Kg in my case).
The batteries directive was better from the start with a weight based qualification value. Someone seems to have been listening.
But, CE testing is a PITA as it favours larger manufacturers.
Here is a typical example: I design and manufacture a control box for a customer. I sell an item for £2,000 with, if I'm lucky, £1,000 profit. The test-lab cost of CE testing is upwards of £6,000. No profit in that scenario.
Add to that the requirement of keeping documentary evidence and traceability of all the parts that I use against the Restriction of the Use of Certain Hazardous Substances ( RoHS ) legislation which now includes Conflict Minerals.
Now, if I made lots of these, and they were identical, then I could have one unit tested and then sell the others with CE marks on them. The CE testing costs can be amortised. That's what the TRV manufacturer is doing.
My units are all one-offs (sometimes three - whahey!) so I have to self-certify. That is, I say that I have designed and tested the equipment against the standards and they meet or exceed them. If someone challenges them then I could me asked to prove it. I have limited test equipment but nothing approaching that of a CE test house so my testing will always be "suspect".
Somewhere along the line we ought to have a lower limit like we do for WEEE and battery directives. I'm not asking for carte-blanch; I still think basic standards are necessary, but at least some wiggle room that allows me to modify my units on-site without initiating a new paper trail.
And finally, we pay (at least we do while we are in the EU), for all of the various directives to be created. Why, oh why, do I have to pay to download the directive pdfs? With so many directives in force, and changes and updates almost every year it adds up to a lot of money. The downloads are over €200 EACH and I probably need 10 of them for electronic goods. Again, this practice favours the larger companies.
In summary, I think we should keep the EU/CE standards; that does seem sensible. But, for small companies making low-volume products for UK consumption only (ie no export) then let's put some fairness into the system.
Reducing the the massive CE/EU overheads on small companies will allow them to grow into larger companies more quickly.
