WIRS Accreditation
The Water Industry Registration Scheme
The Water Industry Registration Scheme is for contractors who provide new connections to the existing water supply or sewerage system. These are referred to as “self-lay” organisations or SLOs.

What is WIRS Accreditation?
In order to be WIRS accredited, the companies undergo technical assessments from LRQA. We assess several areas, including design, construction, connections, commissioning, and project management. By becoming WIRS accredited, companies don’t need to be approved by 22 separate water companies.

About WIRSAE
The Water Industry Registration Scheme – Accredited Entity has been developed to allow contractors, who fulfil the scheme requirements, to become registered as accredited WIRSAE Providers. WIRSAE Providers are referred to as Accredited Entities in the Wholesale Retail Code.
WIRSAE accreditation (and subsequent registration), allows WIRSAE Providers to tender for and to carry out for Retailers’ water supply disconnections and meter installation/replacement works, relevant to their level of accreditation, as an alternative to the Wholesaler, known as the adopting utility, in whose area the work is being done.

Did you also know we could help with MURS.
If you are considering NERS, WIRS, and GIRS for your company, it is crucial to take into account the benefits of also obtaining MURS (Multi-Utility Recognition Status). MURS is not a standalone accreditation; rather, it complements existing certifications. Only companies holding NERS (at 1st tier level), GIRS, and WIRS, while meeting the scheme requirements, will be eligible for automatic inclusion in the MURS register. Although they will not directly hold MURS accreditation, being on the MURS register signifies a higher level of competence and multi-utility capability.
By implementing MURS, the utility industry can eliminate redundant procedures and validation processes that commonly exist across different utility schemes. This streamlines operations and brings several advantages:
- Reduction in the number of annual surveillance visits, which eases the administrative burden on companies while ensuring compliance with standards.
- A revised approach to the 3-yearly re-appraisals will enhance efficiency and effectiveness, leading to smoother evaluations and continued improvements.
- Companies awarded MURS will be promoted for their multi-utility capability through scheme-specific web listings, boosting their visibility and credibility in the industry.
- The implementation of MURS will involve a designated assessor who will liaise with the utility provider and coordinate the input of scheme-specific assessors, ensuring a unified and standardised evaluation process.
Opting for MURS alongside NERS, WIRS, and GIRS will not only enhance your company’s reputation but also streamline validation processes, reduce surveillance visits, and promote your multi-utility capabilities, ultimately leading to increased efficiency and excellence in the utility sector – reach out to the Compliancy Group Team if you feel this is something you would like to consider!
