How Plumbers Are Paid
CIS (Construction Industry Scheme)
The most common payment method for self-employed plumbers and heating engineers working through agencies. 20% tax deducted at source (30% if unregistered). You invoice weekly and manage your own self-assessment tax return.
PAYE (Employed)
Tax and NI deducted at source via standard employment. Common for directly employed plumbers on large mechanical and public health packages. Includes employment rights, holiday pay, and sick pay.
Umbrella Company
Used by many M&E plumbers working via specialist agencies. The umbrella employs you on a PAYE basis. Simpler administration than CIS but typically lower net earnings after umbrella margin.
