Tax and accountancy advice for those on their own or in partnership



Tax, accountancy and business advice for incorporated organisations


Charity and Not-for-profits

Specialist accountancy advice and guidance for those set up to help others


Our Approach

Our approach is to be friendly, honest and approachable. We listen to your needs and tailor your service package to suit you. We offer simple yet effective practical advice on a fixed fee basis.

Are all accountants the same?

Not at all. The word accountant is not protected in the UK, so anyone can call themselves an accountant. We are proud to be a member of the Institute of Chartered Accountants in England & Wales, which means we are subject to strict rules and ethics.


Our Support

We take the hard work out of your compliance such as self-assessment, corporation tax and year end accounts. However our experience goes beyond this, enabling us to offer proactive strategies and business advice to help you grow and achieve your future plans.


Whether it be personal or corporate taxation, we have the knowledge to ensure you are as tax efficient as possible. This is an area many people feel out of their depth with and we want to ensure you, you are in safe hands with us.

Request a call back.

We’re here to help – so do get in touch so we can arrange to meet and discuss your accounting needs.

Our initial consultation is free, and you’re welcome to come to our offices in the centre of Pontyclun or we can come visit you.

    This week has been a difficult week for us here at Derwen Accountancy. We sadly lost one of our cats on Tuesday after a short illness.

    Chloe had been with me 12 years and since lockdown she has sat every day in our office on the windowsill watching us work. There is now a huge space there. So today our "Help Others to Grow" post is very personal. It goes to Barrmore Vets who were absolutely wonderful when I rushed her in on Friday after being taken ill and when I dropped her off on Tuesday. It was especially lovely today to receive a condolence card from them. It is these things which make such a difference. So our heartfelt thanks goes to them today. ♥

    Hi all! Another Thursday and another hints and tips relating to January’s personal tax bill. Last week I spoke about reducing payments on account. This week I want to highlight HMRC’s time to pay arrangement. The arrangement allows individual’s to settle their tax bill over 12 months. Applications for time to pay, on all income tax due on 31 January 2021, will be automatically accepted online by HMRC provided the following conditions are met:-

    • You owe less than £30,000
    • You do not have any other payments plans or debts with HMRC
    • You tax returns are up to date
    • It is done before the start of April.

    For more information go and don’t forget to let us know if you have any questions!
