The prospect of setting up your own business is a massive factor in attracting many people to the plumbing industry. The UK’s high demand for plumbers leaves those with the required skills, qualifications and experience in an incredibly strong position.

In fact, according to various research sources towards the end of 2024 via Approach Personnel, plumbers are one of the most in-demand trades for 2025. The ongoing demand is highlighted by the large vacancy shortfall.

What qualifications do you need to become a self-employed plumber? 

This will depend on whether you plan on working in a domestic, commercial or industrial environment. 

A City & Guilds Level 2 qualification is enough to start carrying out basic domestic plumbing, though those wanting to pursue more advanced work might consider working towards an NVQ Level 2.

To work on a construction site, you’ll need a CSCS card alongside at least an NVQ Level 2.

Any plumbers wanting to work on gas appliances must also be registered with Gas Safe, as this is a legal requirement. This first involves gas training and qualification, work experience and assessments to meet the requirements for Gas Safe registration.

Beyond the formal qualifications, if you’re new to the industry, it’s worth getting a few years of work experience under your belt alongside more experienced plumbers before setting up your own business. 

What do self-employed plumbers earn? 

It can be tricky to put a concrete figure on earning potential, as this varies depending on factors like experience and location. 

However, according to Checkatrade, self-employed plumbers with a good reputation and experience can expect to earn more than £46,000 per year as a sole trader. That goes up slightly more for plumbers who are business owners as a limited company—a notable jump from the £39,644 average salary of an employed plumber according to Reed's average salary checker. 

What personal qualities are required? 

One of the best things about owning your own business is the command it allows over your own time, often leading to a much healthier work-life balance. It does, however, mean you’ll almost certainly need a good level of self-determination and drive as you’ll be responsible for seeking out and managing your own work. 

You’ll need to have patience and be a good communicator as you’ll be dealing face-to-face with clients on a near-daily basis. Resilience, flexibility and organisational skills are also priceless when working for yourself. 

What do I need to do before launching my business?

There are a few legalities and admin tasks to check off as you begin operating. Make sure your business is registered with HMRC, either as a sole trader or a limited company. Both options have their pros and cons. For more information on which path is right for you, visit the Gov website

You’ll also need to look into relevant insurance policies needed to protect yourself, your clients and potentially any staff you hire. 

Public liability insurance covers you should a member of the public be injured, or property be damaged due to work carried out. Employers liability covers team members should they become sick or have an accident at work. It’s also worth considering specific vehicle insurance that covers your tools.  

Along with that, running your own business means you must be able to market yourself. Word-of-mouth remains a key lead driver in the trades, as do other traditional methods like signwriting vans and business cards. However, there’s now also huge importance on having a strong social media presence and a professional-looking website.
