How to Become a Solar Panel Installer in the UK (2025 Guide)
By LTS Training·
Introduction
As I sit down to write this in 2025, the UK solar sector is experiencing a record-breaking boom. According to the UK Government’s Solar Roadmap (UK Government PDF), the country already has nearly 19 GW of installed solar capacity, with a target to reach 45–47 GW by 2030. That’s more than doubling capacity in just five years.
For electricians, the opportunity is huge. Solar PV isn’t just another string to your bow—it’s a fast-growing market where skilled, qualified professionals are in short supply. In this guide, I’ll show you exactly how to become a solar installer, the qualifications you’ll need, and why now is the perfect time to make the move. I’ll also share details of a major live project my organisation is delivering: the Holland Bazaar 250 kWp warehouse installation in Enfield, currently underway with our students at Learn Trade Skills in partnership with Wire Now.
Why Solar Installation Is the Opportunity of the Moment
The UK’s solar market is growing faster than ever. Between January and May 2025 alone, the UK added 513 MW of new capacity, an 8.1% increase over the same period in 2024 (PV Magazine). Solar generation in Q1 2025 was 2.8 TWh, up 45% from last year.
Solar already provides around 5% of our total electricity, but on sunny days, it can exceed 30% (UK Government Solar Roadmap). With zero-VAT on installations, the Smart Export Guarantee (SEG) paying for exported energy, and households desperate to cut bills, the case for solar has never been stronger.
Step-by-Step Pathway to Becoming a Solar Installer
Without these, you cannot legally carry out electrical work in the UK, let alone solar installations. You can
Step 2 – Complete Accredited Solar PV Training
Once you have your electrical qualifications, you’ll need to upskill in solar PV installation. The industry-standard is the Level 3 Award in the Installation of Small-Scale Photovoltaics. This typically takes 3–5 days for qualified electricians and covers:
PV system design and component selection
Mounting systems and roof work
Inverter setup and integration
Battery storage (optional)
Electrical connections, testing, and commissioning
Compliance with MCS standards and UK building regulations
Look for courses accredited by City & Guilds, LCL Awards, or EAL.
Step 3 – Register with the Microgeneration Certification Scheme (MCS)
To legally sign off installations and allow customers to claim incentives, you must be MCS-certified. This involves:
Demonstrating your qualifications
Proving your installations meet MCS standards
Passing an MCS audit
Without MCS registration, you won’t be able to offer zero-VAT rates or SEG eligibility to clients—making your services far less competitive.
The Solar Installation Process
A typical domestic installation follows these steps:
Site survey: Assess roof orientation, shading, and structural suitability.
Scaffolding: Ensure safe roof access.
Mounting rails: Secure to rafters for panel installation.
Panel fitting: Install modules for maximum sun exposure.
Inverter installation: Usually indoors, in a dry, cool space.
Optional battery integration: For storage and energy independence.
Wiring & testing: Connect, test, and commission the system.
Certification: Provide MCS documentation to the customer.
Skills You’ll Need to Succeed
Technical skills:
PV system design and sizing
Electrical integration and testing
Health & safety compliance (especially working at height)
Soft skills:
Customer communication and education
Problem-solving for site challenges
Teamwork with other trades
Earnings Potential and Market Opportunities
In 2025, a typical 2–3 bedroom solar PV installation costs between £6,600 and £8,100 and can save a household up to £1,274/year on energy bills (Homebuilding & Renovating).
For electricians, solar PV is a high-margin service, especially when paired with battery storage. Opportunities are expanding in:
Residential retrofits
New builds (often now specified with solar)
Commercial rooftops
Community energy projects
Large-scale solar farms
Case Study: Holland Bazaar 250 kWp Warehouse Installation (In Progress – August 2025)
One of the most exciting projects I’ve been involved in this year is the Holland Bazaar warehouse solar installation in Enfield.
Project Overview
Capacity: 250 kWp — a large-scale commercial system
Location: Holland Bazaar wholesale market & distribution centre, Enfield (Holland Bazaar)
Team: Students from Learn Trade Skills with expert mentorship from Wire Now engineers
Status: Installation in progress as of August 2025, completion scheduled later this year
Training in Action
Our students have been:
Conducting site surveys and shading analysis
Installing heavy-duty commercial mounting systems
Wiring large-capacity inverters
Preparing the system for full MCS-compliant commissioning
Community Impact
Once live, this system will significantly reduce Holland Bazaar’s operating costs and carbon footprint. For our students, it’s a once-in-a-career early opportunity to work on a major commercial PV system before they’ve even completed training.
This project is living proof that when training is linked with real-world projects, we don’t just produce qualified installers—we produce professionals ready to deliver from day one.
The Road Ahead for UK Solar Installers
With targets of 45–47 GW by 2030 and government encouragement for rooftop, commercial, and even balcony solar (The Guardian), the demand for installers will only grow.
How to Stay Ahead:
Keep updating skills (battery storage, EV charging, smart grids)
Build a portfolio with a mix of residential and commercial work
Partner with reputable training providers and MCS-certified firms
Stay engaged with policy updates to spot new market openings
FAQ
Do I need to be an electrician first?
Yes—UK law requires you to have electrical qualifications before solar training.
How long until I can start installing?
If you’re already a qualified electrician, solar PV training can be completed in a few days, with MCS registration following soon after.
Are incentives still available?
Yes—zero-VAT on installations runs until at least 2027, and the SEG remains in place for exported energy.
Final Thoughts
Becoming a solar panel installer in the UK in 2025 is one of the most strategic moves you can make as an electrician. The market is expanding fast, the earnings potential is strong, and the work is meaningful.
Our live Holland Bazaar 250 kWp project shows exactly what’s possible when training is matched with real industry projects. Whether you’re just starting your electrical career or looking to upskill, now is the time to plug into solar and power the UK’s clean energy future.

Frequently Asked Questions
You need core electrical qualifications including Level 2 and Level 3 Diplomas, 18th Edition certification, Part P compliance, and the Level 3 Award in Small-Scale Photovoltaic Systems (City & Guilds 2922).
The Microgeneration Certification Scheme (MCS) registration is mandatory for providing customers with zero-VAT rates and Smart Export Guarantee eligibility, ensuring installer competence and installation quality standards.
For electricians who already hold the core electrical qualifications, the Level 3 solar PV course typically takes 3 to 5 days to complete.
