Gaia Powered is an ambitious and fast-growing renewables company specialising in air source heat pumps and solar energy installations. We are committed to building a more sustainable future by helping homes and businesses reduce their carbon footprint.

Our sister company, Nelson Charles, is an established M&E contractor delivering high-quality refurbishment projects across London and the South East. This role supports both companies, offering variety and the opportunity to contribute to exciting projects in two thriving sectors.

The Role:

We’re looking for a proactive and organised Office Manager / Admin Assistant to join our small, dynamic team. This is a remote-first role, but we do require1–2 office days per week in East London for team collaboration, meetings, and general support.

You’ll play a key role in keeping both businesses running smoothly—handling day-to-day operations, supporting directors and teams, and ensuring projects and customer service are well-managed.

Key Responsibilities:

  • Manage and coordinate office operations and procedures
  • Provide administrative support to directors and project teams
  • Schedule meetings, maintain calendars, and handle communications
  • Support with HR processes such as onboarding and holiday tracking
  • Oversee basic bookkeeping and invoicing (working with external accountants)
  • Liaise with suppliers, clients, and subcontractors
  • Help implement and improve systems and processes across both companies
  • Support project documentation and compliance

What We’re Looking For:

  • Previous experience in office management or admin roles (2+ years preferred)
  • Highly organised with excellent communication skills
  • Comfortable using digital tools such as Notion, Google Workspace, and Xero
  • Proactive, problem-solving mindset and a can-do attitude
  • Ability to work independently and manage competing priorities
  • Comfortable working remotely and commuting to East London 1–2 days a week
  • Interest or experience in renewables or construction is a bonus

What We Offer:

  • Competitive salary based on experience
  • Flexible working hours (part-time or full-time)
  • Opportunity to grow with a purpose-driven business
  • Collaborative, supportive team culture
  • Real involvement in projects that make a difference

To Apply:

Please submit your CV and a short cover letter outlining your suitability for the role and whether you\'re interested in part-time or full-time hours.

We are reviewing applications on a rolling basis and encourage early submissions.
