Installing solar panels is a significant investment, so choosing the right installer is just as important as choosing the right equipment.
A high-quality installation should provide decades of reliable performance, maximise your energy savings and give you complete confidence that your system has been designed and installed correctly. While there are many reputable solar companies operating across the UK, not all offer the same level of experience, workmanship or aftercare.
Before you commit, here are 10 important questions every homeowner should ask.
This should be your first question.
The Microgeneration Certification Scheme (MCS) certifies installers and renewable energy products to recognised industry standards. Choosing an MCS-certified installer is also a requirement if you want to access certain schemes, such as the Smart Export Guarantee (SEG), which pays homeowners for exporting excess electricity back to the grid.
You can check whether an installer is certified by searching the official MCS register.
Experience matters. Ask how long the company has been installing solar PV systems and whether they’ve completed projects similar to yours.
Every property is different. Roof design, orientation, shading and electrical systems all influence the final installation, so it’s reassuring to choose a company with proven experience across a wide range of homes.
Don’t be afraid to ask how many installations they’ve completed or request examples of previous work.
A reputable installer should be proud to showcase their work. Look for examples that demonstrate:
If possible, ask whether they have completed projects on homes similar to yours. A well-designed installation should enhance your property’s appearance as well as generate clean energy.
No two roofs are the same. Rather than providing a standard quotation based solely on satellite imagery, your installer should carry out a detailed assessment of your property.
This typically includes:
The Energy Saving Trust recommends obtaining a professional assessment before deciding on the size and design of your system.
Not all solar panels are the same. Ask your installer to explain why they’ve recommended a particular:
A good installer should explain the differences clearly without relying on technical jargon or pushing the most expensive option. The right system should be tailored to your home, budget and future energy needs.
Solar panels are built to last, but it’s important to understand exactly what’s covered. Ask about:
Most manufacturers offer long product warranties, while panel performance warranties commonly extend to 25 years or more, although the terms vary between manufacturers. Your installer should explain what happens if something goes wrong and who you would contact.
Installing solar involves more than fitting panels to your roof. Your installer should explain whether they’ll manage:
An experienced installer should guide you through the entire process, making everything as straightforward as possible. The Ofgem website provides further information about the Smart Export Guarantee and how eligible households can be paid for exporting unused electricity to the grid.
The relationship shouldn’t end once your panels have been installed. Ask what support is available after installation, including:
Choosing a company that offers ongoing support provides additional peace of mind throughout the lifetime of your system.
A professional quotation should clearly explain what’s included. Ask whether the price covers:
Understanding exactly what’s included makes it much easier to compare quotations from different installers.
Perhaps the most important question of all. Be cautious if you’re offered exactly the same system as every other customer. A quality installer will design a bespoke solution based on:
The goal shouldn’t simply be to sell the largest system possible, but to recommend the one that offers the best long-term performance and value.
Solar panels are designed to generate clean electricity for decades, so taking the time to choose the right installer is well worth the effort.
