What you do
Pipefitters fabricate and install piping systems that carry fluids, gases, steam, and chemicals in industrial and process environments. The work involves reading isometric and P&ID (piping and instrumentation diagram) drawings, cutting and shaping pipe using saws, grinders, and pipe bending equipment, welding or mechanically joining pipe sections, fitting valves, flanges, expansion joints, and pipe supports, and pressure testing completed systems to ensure they are leak-free. Pipefitters work on new installations during construction phases as well as maintaining and modifying existing pipework during planned shutdowns at operational facilities.
Major sectors for pipefitters include oil refineries, petrochemical plants, power stations, food and beverage processing, pharmaceutical manufacturing, shipbuilding, and district heating systems. Many pipefitters develop a welding specialism — coded pipe welding (to standards such as BS EN ISO 9606) commands significantly higher rates. Work often follows large capital projects, and specialist pipefitters are in demand across the UK and internationally. Progression leads to pipework supervisor, project engineer, or running an industrial pipework contracting business.
Why this career is resilient
Pipefitting sits within a category of skilled trades that has no realistic automated substitute — every industrial facility with pressurised systems requires pipefitters for installation, maintenance, and modification work. The UK's process industry base — refineries, chemical plants, power generation, water treatment, and the growing hydrogen and carbon capture infrastructure — all depend on qualified pipefitters who understand both fabrication and the behaviour of fluids under pressure.
Planned shutdown maintenance at process facilities creates recurring, high-value contract work that specialist pipefitters can depend on year-round. The combination of fabrication, welding, and systems knowledge means pipefitters can command some of the highest day rates in the construction and engineering trades — particularly those holding coded weld qualifications. The expansion of offshore wind, hydrogen production, and district heating networks is creating new long-term demand above and beyond the established process industry base.
A typical day
Start the day on a refinery shutdown project — review the day's iso drawings with the supervisor and mark out the pipe route for a new steam distribution line. Cut and prepare pipe sections, tack-weld joints for the coded welder to complete, and fit pipe hangers and supports to the structural steelwork. After lunch, assist with pressure testing a newly completed section of process pipework — isolate the system, apply test pressure with nitrogen, walk the line checking for leaks, and record the test results on the documentation pack. End the day completing a spool fabrication in the workshop ready for installation tomorrow.
Routes in
Apprenticeship
Earn while you learn: work with an employer and study part-time, leading to a nationally recognised qualification. Typically funded by the government and your employer.
Full-time college course
Study full-time at a further education college, usually for 1–2 years. You will need to fund yourself or apply for a student loan (available for Level 4+ courses).
Employer-funded training
Some employers — particularly the NHS, emergency services, and larger care providers — run their own funded training programmes. You apply for a job and train as you work.
Pay and costs
Earning potential: Trainee pipefitters earn £24,000–£30,000. Qualified pipefitters earn £34,000–£46,000. Coded pipe welders and specialist pipefitters earn £45,000–£65,000. Contract day rates on shutdown projects: £250–£450 per day. Offshore and international project work attracts higher rates.
Training costs: Apprenticeship: no upfront cost. NVQ via employer or college: £2,000–£4,000 if self-funding. Coded welding qualification (per test piece): £200–£600. Personal hand tools and PPE: £400–£1,000. CCNSG Safety Passport for industrial sites: £100–£150.
