With energy bills rising and climate goals becoming more urgent, more UK homeowners and business owners are turning to solar energy. But choosing the right solar PV system installer is just as important as deciding to go solar in the first place. A well-installed system will perform efficiently for decades—while a poor installation can lead to unnecessary costs, underperformance, and even safety issues.
To make sure you’re making the right choice, here are five key things to look for in a reliable solar PV installer:
1. MCS Certification
In the UK, any reputable solar PV installer should be MCS-certified (Microgeneration Certification Scheme). This certification ensures that the installer meets high standards for both products and workmanship. It also means your system qualifies for the Smart Export Guarantee (SEG), allowing you to earn money for excess energy you export back to the grid. Always ask for proof of MCS accreditation before committing to an installer.
2. Experience and Track Record
Solar technology is constantly evolving, and the installation process requires specialised knowledge. Look for a company with a solid track record and years of experience in solar PV installations. Ask to see case studies, photos of previous projects, or customer testimonials. A well-established installer will be happy to show their work and explain the systems they’ve delivered for both residential and commercial clients.
3. Tailored System Design
No two properties are the same, and a “one-size-fits-all” approach won’t give you the best results. A reliable installer will carry out a full site survey, assess your energy needs, and design a system tailored specifically to your roof size, orientation, shading, and usage patterns. If an installer gives you a quote without thoroughly inspecting your property, consider it a red flag.
4. Transparent Pricing and Clear Warranties
Solar PV is a long-term investment, and you deserve clear, upfront information about the costs. A trustworthy installer will provide a detailed quote with no hidden fees and will explain the return on investment you can expect. Make sure they offer solid warranties on both the system (typically 20–25 years for panels) and their installation work (usually 5–10 years). Ask what’s covered—and what’s not.
5. Aftercare and Ongoing Support
Solar systems are low-maintenance, but issues can occasionally arise. Choose an installer who offers ongoing support, routine maintenance, and a clear aftercare policy. You should feel confident that your installer will be there if you have questions, need repairs, or want to expand your system in future. Good customer service doesn’t end once the panels are on your roof.
