CIS and Electrician Work: What You Need to Know
Electrical installation work on construction projects falls under CIS. Electricians working as subcontractors must ensure their invoices show the correct CIS deduction rates.
Electricians typically carry out first and second fix wiring, consumer unit installation, testing and inspection, commercial electrical fit-out, EV charger installation, and data cabling. Common contractors who engage electricians as subcontractors include main contractors, house builders, commercial developers, local authorities, and M&E contractors.
CIS Deduction Rates for Electricians
The deduction rate applied to your labour payments depends on your CIS registration status:
- 0% — Gross payment status (you've applied and been approved by HMRC)
- 20% — Registered CIS subcontractor (standard rate)
- 30% — Unregistered subcontractor (higher rate — register to reduce this)
Frequently Asked Questions
Do electricians have to use CIS?
Yes, if you do electrical installation work as a subcontractor on UK construction projects. HMRC includes electrical work within the Construction Industry Scheme.
What is the CIS deduction rate for electricians?
The standard rate is 20% on labour if you are registered with CIS, or 30% if you are not registered. Electricians with gross payment status receive full payment without deductions.
Does CIS apply to EV charger installation?
Yes, if the EV charger installation is part of a wider construction project (e.g., a new build or commercial development). Stand-alone domestic EV charger installs for homeowners are typically outside CIS.
