How to Apply
Before making your formal application to NSAI Agrément:
- You should ask a competent Simulator to undertake an energy rating of your window(s) on your behalf.
- From this exercise you will obtain a WEP energy rating for your window design.
- If you are satisfied with the WEP index achieved, you should submit all relevant technical documentation (for review) along with a completed application form and the appropriate fees to NSAI Agrément.
- A production inspection audit of the manufacturing/Quality System will then be carried out by NSAI Agrément.
- Subject to a satisfactory review of your technical submission and a successful audit, NSAI Agrément will then allocate a WEP registration number to each window system(s) and place this WEP certificate on our website.
- Once approval has been received, the window manufacturer/supplier is entitled to mark their product(s) with the WEP number and affix the WEP label on their product(s).

On 1st July 2013 the EU Construction Products Regulation (CPR) (EU) 305/2011 came into effect and as a result, Windows and doors within the scope of EN 14351-1:2006+A1:2010 must be CE Marked.
In June 2015, The Department of the Environment, Community and Local Government have announced details of a Market Surveillance Campaign which will target a random sample of manufacturers, importers, distributors & retailers of windows and doors across the country.
The Department of the Environment, Community and Local Government will co-ordinate this national campaign, which will be undertaken on the ground by the 31 local building control authorities, and have prepared an Information Note (see link below) for circulation among economic operators to inform them of the campaign and what to expect should they receive a visit from a building control authority.
