What People Say About Us

Client Testimonials

After experiencing difficulties with three previous accountants, finding Steve at J Sweeney Accountants has been transformative for both my business and personal finances. His approach stands out for several key reasons. Unlike my previous experiences, he took the time to thoroughly understand my company's structure and financial goals, demonstrating a level of engagement I hadn't encountered before. His work has not only saved us significant money but has also given us peace of mind knowing our finances are in capable, professional hands. If you're looking for an accountant who will truly partner with you to optimise your business's financial position, Steve at J Sweeney Accountants is, without doubt, the professional you need.

Benson's wouldn't run the same without Joseph and the team at J Sweeney. A seamless switchover, not a day goes by without knowing the stress and worry was lifted, our business is a small family run agency which has grown with the support of J Sweeney. We look forward to more years ahead and strongly recommend.
Hayley SelwayManaging Director, Benson's Agency
As a result of J Sweeney’ expertise the business gained much needed clarity on its financial position and was able to focus on issues raised. Financial information was more freely available and supplied 50% quicker than our previous advisors. James’ hands on “part of the team” approach was exactly what the company needed after its recent acquisition. Having James on-board was essential to the integration of the businesses.
Gary KiernanManaging Director, Lonsdale Direct Solutions
We have been using J Sweeney Accountants for a couple years now and using Steve Thomas as our accountant since we set up our business. Steve is not only incredibly professional, but very knowledgeable on all business areas. He continues to save us greatly with our taxes and is on hand to answer all questions. He supported and helped us set up the business from the very start. J Sweeney are approachable, professional and always available to answer any questions, their rates are competitive, and we personally wouldn’t use another accountancy firm. I highly recommend them for all business needs.
Lisa MorphyMorphy and Sons Ltd
For the last 5 years J Sweeney Accountants have been there for me every step of the way, I cannot recommend them enough. I don’t think I’d be able to do what I do today without their support. I’m solvent, I’m doing well and I do think it’s all down to the support I get from J Sweeney Accountants.
Simon Squibb Entrepreneur
J Sweeney help us by coming on site and sitting with us and being an addition to our team, as opposed to just being on the other side of an email or phone. They make such an impact compared to our previous accountants. Joe and the whole team just speak to us as we need to be spoken to, so we can understand and progress and then move forward.
Nicola TilleyMore Driver Solutions

Richard GordonGreedy Gordons
Our business is growing and we needed an accountant to manage our payroll, we also needed advice from J Sweeney Accountants to make sure we were managing our accounts correctly and to help us make the right decisions. J Sweeney is proactive, reactive and flexible for our small business needs.
Florian PoupinelV&B Northampton
As the business grew, we had more challenges that just took more of our time. I’m a big believer that if there’s something you can’t do, you get the best people to do it correctly for you which free’s us up as a sales business.
Mike HodderMotech Performance Ltd
Steve Thomas is invested in helping me build my business and contributing to our shared success. It’s an area I have absolutely no concerns or desire to change. With regular reviews and conversations to understand how the month/quarter/year is going. Steve is with me every step of the way, it doesn’t feel like an external team, my trust in them has been earnt and wouldn’t consider using anyone else! Steve is exceptional. I’d definitely reach out to him if you’re looking for an expert to lead your company accounts so you can get back to leading your business.
