Simple Window Energy Ratings stickers, featuring your brand to help consumers trust that your products are the best choice for their home.
Join the Energy Ratings SchemeOur Energy Ratings Scheme has been designed to help you prove the performance of the products you supply.
Our Window Energy Rating (WER) labels are designed to be consumer friendly. They avoid all technical jargon and we use simple-to-follow graphics to support your sales process. With the Certass Energy Ratings Scheme – also known as Thermal Ratings Register – you can have unlimited WER labels featuring your company name, helping to promote your business in the marketplace.
You can easily update your Window Energy Ratings stickers in line with your latest window specification, so you can meet the demands of your customers whilst incorporating new window and door technologies into your manufacturing process.
The unique design of our consumer-friendly labels makes it easy to understand, using the familiar ‘rainbow’ ratings system that homeowners can find on other energy rated products in their home, such as fridge freezers. As well as the A-G Window Energy Rating, our labels feature a unique Light Energy Transmittance and Heat Retention rating, to help promote the benefits of triple glazed units. Often, triple glazed units do not perform well with the WER rating methodology, as light transmittance is reduced due to the third pane of glass. With our simple-to-follow graphics, the beneficial effect of the improved U-Value is demonstrated clearly for all to see.
Window Energy Ratings are used as a measure of the energy performance of a window.

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 brought mandatory CE marking to glazing products 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).
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 is make sure you buy the complete window product with a CE Mark from your supplier (the manufacturer).
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.
