When is an MSc Computer Science degree worth it?
An MSc Computer Science is worth it if you have a clear career goal and skills you want to develop for going into a technology role. It can also be an exciting option if you're looking to build on existing computing experience or develop advanced knowledge for going into more specialist roles. Or, perhaps you are just passionate about learning how computer science is evolving and want to explore whether it's a career route you want to go down.
As technology advances, postgraduate study can also help you understand new developments and build the skills and confidence to work with them. You also don’t always need a computing background to get started, and some courses welcome graduates from other subjects. This gives you another route into computer science and a chance to take your career in a new direction.

Employers are conservative and understand exactly what a master's degree signals, for example, the breadth of content, the volume of work, and the depth of thinking. It's not so much the specific tool that's important; it's the underpinning theoretical principles and the ability to think critically and solve problems.
A route to move into computer science from another field
You don't always need an undergraduate bachelor's degree in computing to study an MSc in computer science. Some courses are designed for graduates from other subjects, giving you a route to build technical knowledge and work towards a career in technology. For example, you might have studied business, finance, or engineering, and want to develop your computing skills to move into areas such as software development, data, AI or cyber security.
In some cases, transferable skills from a different undergraduate course can even benefit you in a computer science master's course. For instance, perhaps you've developed useful problem-solving and analytical skills in a mathematics undergraduate course that you could take advantage of this in your MSc Computer Science programme.

AI isn't replacing jobs, it's changing them. The jobs are still there, but you need an AI skill set in addition to the traditional things, and that applies across every discipline, not just tech. At Walbrook, this is reflected in the programme design: AI has been embedded as a central thread running through every module.
Salary and return on investment
In some cases, an MSc Computer Science could increase your earning potential in the job market, particularly if you use valuable knowledge you gained to reach more senior roles. For example, the average yearly income for an AI and machine learning engineer is £85,000, but you could make up to £120,000 depending on your experience and knowledge. The Tech Nation Report 2026 found the UK tech sector to be worth $1.6 trillion, growing faster than its European rivals. So, the market is definitely still there for graduates going into a computer science role. Find out more about the tech market today.
But if you're considering an MSc in computer science, it's still important to first consider the course cost and study time against the long-term gain that may come from the course. Take into account your current outgoings and living expenses to make sure it is something you can currently afford. Read our complete guide to studying computer science for more information on the programme.
Salaries in computer science roles
The typical salary for computer science professionals varies a lot depending on location, role level, and experience. You can expect an average salary of £70,000 for a software developer role in the UK, while the average salary for a data scientist in the UK is £75,000.
However, in more senior roles, you could earn even more. For instance, DevOps engineers may earn around £90,000 per year depending on level and location. Additionally, a blockchain engineer in the UK can earn up to around £80,968.

When an MSc may not be the right choice
Though it can be valuable for many professionals, an MSc in computer science is not always essential for every career in technology. For example, if you already have the skills and experience needed for your chosen role, gaining more practical experience or taking a shorter course may be a more suitable option.
Alternatively, if you have lots of tech experience and are hoping to move into a leadership role, an MBA might be an ideal route for you. For example, at Walbrook, we offer MBAs in the tech fields of cyber security, AI, and data analytics. You can explore our online MBAs here to find out more.
It is worth researching the roles you are interested in before applying. Look at the skills, qualifications and experience employers commonly ask for, then consider whether a master's will realistically help you meet those requirements and support your longer-term career plans.
