About Us

Hello, my name is Jonathan Mainwaring and I am a director of TJ Accountancy Ltd.

After working for a number of larger accountancy practices for twelve years in Swansea and the surrounding areas I then decided to set up my own accountancy practice with my wife, Teresa back in 2008.

I’ve always wanted to pay the lowest amount of tax as I could (who doesn’t!) and I found it frustrating when working for some of my previous firms that I previously worked for in that the accountants didn’t seem to take the time working with the client, finding out more about their businesses and therefore ensuring that the clients paid as little tax as legally possible.

At this point I decided to set up TJ Accountancy Ltd to offer a more personal service to clients and basically be the accountant I would like to have in my business.

After starting off with a handful of clients, we now act for over 200 small businesses and individuals, not just in the UK but as far as away as Australia!

The majority of our clients have come to us by being referred by existing clients which we think is testament to the excellent service we provide.

We offer new clients a free, no obligation appointment to discuss how we can help their businesses and also to give the client the opportunity to meet us and to be confident that we are the firm they wish to look after their accountancy and taxation affairs.

If you think we could be of help to your business or indeed if you have any questions then please do not hesitate to get in touch with us.
