A service review from a recruitment agency for JSA Services
Amazing Service!

Over the last couple of years, I had the pleasure of working with Maria Constantinou, who is my point of contact at 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.

Maria is fantastic, very responsive and personal regardless of whether it’s a client or contractor, she is always there to help. She takes the stress out of any difficult situation and seeks immediate solutions, answering questions swiftly and clearly. I highly recommend both Maria and JSA Services.


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

We have worked with Natalie, Caroline, and JSA for a number of years and they’ve always provided outstanding service to our staff and candidates.

No matter what time of the day or week (including weekends), they are on hand to support our candidates and answer their queries. I would highly recommend JSA.

A service review from Carrington West recruitment agency for JSA Services

Seamless Service

We have been partnered with JSA for 2 years and have never been disappointed with the quality of their service. Del and his team are always on hand to help us.

They have been especially great with IR35 coming up. As you can imagine, this could have caused unprecedented strain on our business without the help of JSA’s experts and the IR35 Complete platform. IR35 Complete has been seamless and easy to use from set up through to day-to-day use. A highly efficient platform that processes our IR35 assessments and helps us keep on top of our compliance responsibilities.

Managing Director at Carrington West

Proactive and Efficient

We couldn’t have asked for better support throughout our IR35 preparations. JSA did not hesitate to give us their time and expert input, both proactively and reactively. Not only were the JSA team highly knowledgeable, but they were also great at communicating the complexity of IR35 and helping us understand how the legislation relates to our business and our specific circumstances.

It makes a big difference on a project like this, to work with people you respect, but who are also very likeable and generous with their time and knowledge.

A service review from Carrington West recruitment agency for JSA Services


We have been working with the team at JSA for over 4 years. The service we receive is second-to-none. JSA has helped us prepare for IR35 and also address the many changes to contract conditions in that time. Despite daily calls from ‘other’ Umbrella companies, we work exclusively with JSA for this very reason.

We have a mutually beneficial relationship built upon trust and a high level of services to us and our contractors. Long may it continue. I thoroughly recommend speaking to JSA forĀ all your Umbrella needs.
