Founded in 1982, Castle Computer Services provides accounting and financial management software, business intelligence solutions, cloud and managed IT services throughout the UK, across a wide range of industries.

In 2018 we joined Kick ICT Group to form Scotland's largest independent IT services business.

With over 35 years experience delivering business software and managed services to organisations across the UK we’re a safe pair of hands. A reliable partner that you can turn to and trust. You can be sure that our products are class-leading and our services are underpinned by proven methodologies such as PQIS (Professional Quality Implementation Services) and ITIL (IT Infrastructure Library) that ensure effective delivery.

We go further than anyone else when it comes to listening to your needs and aspirations, engaging in a business discovery exercise at the outset and continuing with account management, consultant engagement, training and regular events that bring together customers to form communities.

It’s our goal to provide the best support for our customers and identify where new technologies can help drive your digital strategy forward. We strive to build long standing customer relationships and many of our team come with practical industry expertise so we understand the challenges your organisation faces.

Combining understanding with technical expertise enables us to deliver innovative solutions. In-depth understanding of the products we sell, through ongoing supplier accreditation and internal training, has given us the scope to develop new ways of utilising and integrating them. As a result, you receive functionality that cannot be found elsewhere.

Our culture and values encourage internal collaboration where we work together as one team to ensure success of every project using our unique expertise of both business software and managed IT service implementations. We’re the only IT team that you need.

Our Values

Ensuring that each customer receives the same standard of service is important to us, that’s why each member of the Castle team works hard to adhere to our values.


We believe in long term relationships and that giving honest and impartial advice, that is in our customers’ best interest, is also in our best interests.


We operate a flat company structure where every employee has operational responsibility and is responsible for ensuring commitments are delivered by the company.

Everything Matters

At Castle, we believe everything matters and that any small improvement that can be made, should be made, if it enhances our clients’ experience.


We want our customers to know that a Castle promise is a promise that doesn’t get broken or re-qualified, it endures.


A culture of partnership creates better understanding of our clients’ needs, it engenders trust and improves outcomes.

Fairness Prevails

Fairness to customers and staff is an important cornerstone in the way we work. We think it’s a principle that allows for longevity in relationships.

Ask the experts. We're here to help.
