Bespoke accountancy advice for
contractors in the energy sector.



Contracting in the Energy Sector

Major changes are happening in the energy sector, especially in the UK as the Government turns to a more green energy scheme. You need to be focusing on maximising your skill set and acquiring the best opportunities, not thinking about your accounting responsibilities. We’ll take care of all your tax, compliance, and accounting tasks, whether you’re working here or further afield, so you don’t have to worry about anything other than doing what you do best.

How We Can Help

We’ll be here for you no matter where your career takes you:

  • Our Umbrella service includes comprehensive insurance cover, ensuring sector-specific requirements are covered for your role.
  • Our international payroll options ensure you can work anywhere in the world while maintaining one payroll service that takes care of all your requirements.

Testimonials from our Agency Partners

Makes Life Easier

I’ve had multiple Umbrella companies request I send my candidates over to them, but when I or the candidates need to ask them questions, the Umbrella companies never answer. Never have I ever had an issue with JSA, they’re always extremely helpful and timely with email responses.

Would 10/10 recommend to any agency to use JSA – makes your lives easier dealing with people who never let you down.

Amazing service!

Over the last couple of years, I had the pleasure of working with JSA. We, as a recruitment agency, work with many Umbrella companies, but JSA certainly stands out with not only good service, but competitive offers. Every time our contractors require good and reliable service, I am happy to recommend JSA for an Umbrella or Limited Company set up. 

Very responsive and personal regardless of whether it’s a client or contractor, they are always there to help. JSA takes the stress out of any difficult situation and seeks immediate solutions, answering questions swiftly and clearly. I highly recommend JSA.
