Advice and approval

Guidance to Applicants

1. Introduction

 Advice Sheet 1 outlines the essential elements of the approval application process. You are strongly recommended to read this before proceeding further with your application.

The approval process under Regulation 31(4)(a) is subject to charges . Full details are provided in the Guidance document (PDF 119KB).

Any application for approval which has not progressed for six months will be closed and a new application will need to be made.

2. Product Re-approval

In order to provide assurances that products included in the list have not changed and so continue to be suitable for contact with drinking water, all products are now subject to a re-approval process five years after the initial approval date.

3. Advice Sheets

Advice Sheet 1 gives an overview of the regulatory requirements and explains how to make an application for approval. Advice sheet 2 gives guidance on what will be required in your Instructions for Use document – it is very important that any IFU submitted to us conforms fully with these requirements, otherwise your applications may be delayed. Advice sheet 11 explains the re-approval process.

The remaining sheets provide information on the application requirements for certain product types.
