If you’re thinking about starting a plumbing or construction business, the first thing you’ll hear is “you need a licence”. It sounds simple, but the details can trip up anyone new to the trade. Below we break down the key licences you’ll need, where to get them, and how to keep everything legal without drowning in paperwork.
In the UK, two main licences cover most plumbing and construction work: the Gas Safe Register for any gas‑related jobs and the CSCS card for construction sites. If you plan to install or service gas appliances, you must become a Gas Safe registered engineer – that means completing an accredited training course, passing the exam, and renewing every year. For general building work, the CSCS (Construction Skills Certification Scheme) card proves you’ve met health‑and‑safety standards. Many employers won’t let you on site without it.
Beyond these, local councils often require a building control registration for larger projects. This isn’t a licence you hold forever; it’s a notification you send before work begins, showing your plans meet the Building Regulations. If you’re doing work on a private home under a certain value, you might be exempt, but it’s safest to check the council’s website.
First, find an approved training provider. For Gas Safe, look for courses listed on the Health and Safety Executive (HSE) site. They usually run over a week, mixing classroom theory with hands‑on practice. After you pass, you’ll receive a licence number that you can display on your business cards and website – this builds trust with customers.
CSCS cards are a bit easier. You’ll need to pass the CITB Health, Safety and Environment test (often called the “rose test”). Once you’ve cleared that, you can apply online, upload proof of qualifications, and get the card mailed to you within a week.
Don’t forget insurance. Even with a licence, you’ll need Public Liability Insurance (PLI) and, if you have employees, Employers’ Liability Insurance. Many clients ask for proof before you start a job, and insurers often require proof of your licences to give you coverage.
Renewal is another piece of the puzzle. Gas Safe licences expire every year, and you’ll need to retake the competency assessment to keep them active. CSCS cards last three to five years depending on the level, after which you’ll need to prove continued training or experience.
Finally, keep records of every licence, renewal date, and training certificate. A simple spreadsheet or cloud‑based folder saves you from missing a deadline and facing fines.
Getting the right licences might feel like a chore, but it protects you, your crew, and your customers. It also opens doors to larger contracts that only work with fully certified firms. Follow these steps, stay on top of renewals, and you’ll spend more time on the job and less time worrying about compliance.
