Supplier Registration

During planning, construction and operation, our new nuclear plant will bring significant new business and employment opportunities. Over the next decade, Horizon and the Delivery Team intend to work with suppliers to expand and develop the role of the UK supply chain. We are in the early stages of a complex major infrastructure project and we are keen to build strong relationships at every level of the supply chain. Our current focus is on early engagement with prospective suppliers, investigating your interest, capabilities, experience and aspirations to develop your business.

At Horizon, we believe the UK has the substantial experience and capacity to assist the delivery of the developments at our Wylfa Newydd and Oldbury sites. The scale and scope of these projects offer valuable opportunities for suppliers.

Any prospective supplier must demonstrate they are capable and competitive while assuring safety and quality through systematic project risk management during delivery. At each site our principle commitment is to maintain high safety standards and we will be looking to build relationships and collaborate with organisations that share our culture, values and vision.

Focus on the future 
We would like to ensure small and medium sized companies local to our sites understand the possible opportunities. We will work with our Tier 1 suppliers and selected local and national organisations to assist local businesses that want to be considered for direct and indirect subcontracting opportunities and potentially develop their readiness levels to meet basic tendering and sub-contracting requirements.

How can companies get involved?
In this section you will find the information you need to express your interest in participating in the delivery of our projects.

At this early stage of development, we are encouraging suppliers to introduce their business capabilities and outline their areas of expertise. The first step is to complete our online registration process.

Please note – this is neither a pre-qualification system nor an approved supplier listing. Where relevant and with your permission we may share relevant information with our Tier 1 partners.

How will the process work?
As procurement plans are developed we will explain in more detail how future opportunities will be advertised and procured.

What is the registration process?
The registration process is one of the tools we will use to develop the supplier selection process. It constitutes a company registration so only one entry per company or business is required. Information submitted must be an accurate and truthful reflection of your organisation. The registration process should take no more than 30 minutes.

What do companies need to do before registering?
It is advisable to check with your colleagues that your company registration has not been completed previously.

We believe that up to 60% of the value of the first generating unit will be spent on UK-sourced materials, personnel and services.
Our projects will represent a multi-billion pound investment over the coming decades and each development site could see a peak workforce of up to 6,000 during construction.
