Assistant Company Secretary in Windsor

Join us, be part of more. We’re so much more than an energy company. We’re a family of brands revolutionising how we power the planet. We’re energisers. One team of 21,000 colleagues that’s energising a greener, fairer future by creating an energy system that doesn’t rely on fossil fuels, whilst living our powerful commitment to igniting positive change in our communities. Here, you can find more purpose, more passion, and more potential. That’s why working here is #MoreThanACareer. We do energy differently - we do it all. We make it, store it, move it, sell it, and mend it.

We have an excellent new opportunity for an Assistant Company Secretary to join our Legal, Regulatory Affairs, Ethics & Compliance, and Secretariat Function (LRECS).

Please note that over the coming months we will have an office in Reading and also London Paddington where you may be required to work.

Here’s who we’re looking for:

• A qualified Company Secretary.
• Experience within Financial Services or at a global company (public or private).
• Working knowledge of UK listed-company governance and Secretariat processes (ARA/AGM, DTRs, UK Listing Rules) with a practical, delivery mindset.
• Demonstrable experience in subsidiary governance / entity management.
• Excellent quality assurance skills and meticulous attention to detail.
• Proven project management capability across tight, multi-stakeholder timelines (ARA/AGM and entity compliance cycles).
• Confident stakeholder management; able to influence and collaborate with senior leaders and external agencies.
• Proficiency with Blueprint/Diligent, SharePoint and MS365 collaboration tools.

Why should you apply? We’re not a perfect place – but we’re a people place. Our priority is supporting all of the different realities our people face. Life is about so much more than work. We get it. That’s why we’ve designed our total rewards to give you the flexibility to choose what you need, when you need it, making sure that you and your family are supported not only financially, but physically and emotionally too.

If you’re full of energy, fired up about sustainability, and ready to craft not only a better tomorrow, but a better you, then come and find your purpose in a team where your voice matters, your growth is non-negotiable, and your ambitions are our priority.
