Installing solar panels is a long-term investment – but your results depend heavily on who installs them.
Choosing the right company ensures your system performs efficiently, qualifies for export payments, and comes with strong warranties. Here’s what to look for when comparing installers.
Why Accreditation Matters
MCS Certification
The Microgeneration Certification Scheme (MCS) is the UK’s quality standard for renewable energy installers.
An MCS-accredited company guarantees:
-
Systems meet strict design and safety standards.
-
Installers are trained and regularly assessed.
-
You’re eligible for Smart Export Guarantee (SEG) payments.
-
Workmanship and equipment are fully warrantied.
Without MCS accreditation, your solar system won’t qualify for export payments or government-backed schemes.
What Makes a Good Solar Installer?
When comparing quotes, check for these key qualities:
-
Tailored Surveys – A professional installer will visit your property to assess roof orientation, pitch, and shading — not just rely on Google Maps.
-
Transparent Quotes – Make sure quotes include scaffolding, electrical work, DNO approval, and warranties.
-
Strong Reputation – Look for independent reviews on Trustpilot or Which? Trusted Traders.
-
Aftercare and Monitoring – Choose companies that offer system monitoring and maintenance support.
-
Battery & EV Integration Expertise – If you plan to expand later, pick an installer experienced in full home energy systems.
At Sustain Heating, every project starts with an in-person survey and tailored design to ensure maximum output and long-term value.

Why Choosing the Right Installer Saves You Money
While it’s tempting to go for the cheapest quote, “budget” installations often cut corners.
A high-quality system from an accredited installer ensures:
-
Correct system sizing and efficiency.
-
Proper documentation for export payments.
-
Long-term reliability and minimal maintenance costs.
It’s an investment that pays off in both performance and peace of mind.
