Do Solar Installers Need to Be NICEIC Registered?
The short answer is: not necessarily NICEIC specifically – but you do need to be registered with a competent person scheme, and NICEIC is one of the most common routes. This is a distinction worth understanding, because it affects which certification route you choose.
What NICEIC Registration Actually Is
NICEIC (National Inspection Council for Electrical Installation Contracting) is one of the UK’s main competent person scheme operators for electrical work. Being NICEIC registered means:
- Your business has been assessed as competent to carry out notifiable electrical work
- You can self-certify notifiable electrical work (including solar PV electrical elements) without involving building control
- Your NICEIC registration number appears on your certificates and is verifiable online
NICEIC is the largest electrical competent person scheme in the UK but it is one of several options. The alternatives include:
| Scheme | Notes |
|---|---|
| NAPIT | Electrical, renewables, plumbing |
| ELECSA | Part of NICEIC Group |
| STROMA | Energy and renewables focus |
| BESCA | Electrical and building services |
All of these are approved competent person schemes under Building Regulations. For solar purposes, they are equivalently valid.
Why a Competent Person Scheme is Essential for Solar
Solar PV installation involves notifiable electrical work under Part P of the Building Regulations. Notifiable work must either be:
- Self-certified by a registered competent person (requires scheme registration), or
- Notified to building control before work begins
In practice, option 2 is commercially unworkable for solar installation – the timeline, cost, and customer friction involved in building control notification for every residential job makes it impractical. Every commercially viable solar installer uses self-certification via a competent person scheme.
MCS certification requires competent person scheme registration. To be MCS certified as a solar PV installer, your electrical work must be self-certifiable – which requires NICEIC, NAPIT or equivalent registration. If you’re not already registered, getting registered is a prerequisite for MCS certification.
NICEIC vs NAPIT for Solar Businesses
Both are strong choices. The practical differences:
| NICEIC | NAPIT | |
|---|---|---|
| Size | Largest UK scheme | Second largest |
| Renewables focus | Good – solar category well established | Strong renewables offering |
| MCS pathway | Direct MCS certification available | Direct MCS certification available |
| Annual cost | £500-900+ | £400-800+ |
| Surveillance | Annual + random site visits | Annual + random site visits |
| Reputation | Very well recognised | Well recognised |
For a new solar business, either is appropriate. If you’re already registered with one for electrical work, stick with them and add solar. If starting fresh, compare their solar MCS packages – NAPIT’s combined electrical + MCS offering is worth comparing against NICEIC’s equivalent.
The Registration Process
For a new business not currently registered:
- Choose your scheme
- Apply online – submit qualifications, insurance, business details
- Desktop assessment by the scheme
- Technical assessment – a scheme assessor visits to verify your competence
- Registration granted
Timeline: typically 4-8 weeks.
For an existing registered business adding solar:
If you’re already NICEIC or NAPIT registered for general electrical work, adding solar PV as an approved scope is generally faster and cheaper than a fresh application. Contact your existing scheme for details.
Frequently Asked Questions
Can I install solar panels if I’m not NICEIC registered? You can carry out the mechanical installation (mounting, racking) without electrical registration. But you cannot self-certify the electrical work – you’d need to notify building control for every job, which is impractical commercially. All viable solar installers are registered with a competent person scheme.
Is NICEIC registration the same as MCS certification? No. NICEIC registration covers your electrical competence and self-certification rights under Building Regulations. MCS certification covers your solar installation quality standards and enables your customers to access the Smart Export Guarantee. You need both for residential solar work.
How much does NICEIC registration cost for a solar installer? Annual fees vary based on scheme category and business size – typically £500-1,000/year for a small solar installation business. See niceic.com for current pricing.
What happens if I lose my NICEIC registration? You lose the right to self-certify electrical work. Any installations made while unregistered would be non-compliant. Your MCS certification would also be at risk, as it requires maintained competent person registration.
