CE Marking for Micro Enterprises

The CE mark is a common place sight on today’s consumer electronics as well as a host of other products we all use every day. The Construction Products Regulation now brings mandatory CE marking to glazing products as from 1st July 2013. 

The manufacturer of the window/door product is the company responsible for the CE marking of the window/door product.

The CE Mark applies to the complete product, i.e. the whole window (both frame and glazing unit).

So, are you a manufacturer or installer?


If you as an installer purchase a window including glass from a single supplier under one order, then your supplier is the manufacturer and responsible for providing you with a CE Marked product as from 1st July 2013.

In this case, all you need to do, from the 1st July 2013, is make sure you buy the complete window product with a CE Mark from your supplier (the manufacturer).


If you purchase the window frame and glazing unit from separate suppliers (or manufacture both) then you are deemed to be the manufacturer, as you are buying components (each of which should be individually CE Marked) and you must CE Mark the completed whole product.

In this case, you will need to know more about CE Marking. The following information outlines what you need to do next.

The Thermal Ratings Register has developed a CE Mark calculator suitable for micro enterprises.

A micro enterprise is defined in European legislation as a company with fewer than 10 employees with an annual turnover/balance sheet not exceeding 2M Euros (for those of you that fall outside this we have partner companies that can help).

The CE Mark calculator is only available to TRR members. If you are a member of the Certass Competent Person Scheme and meet the above definition of a manufacturer then joining the TRR will give you the required CE Mark as well as access to our industry leading simple WER calculator.

NOTE: You will need to have Factory Production Control System (FPC) in place to the requirements of BS EN 14351-1:2006 +A1:2010 (there are a number of companies that can supply this, in some instances for free).
