How to Choose Certified Solar Installers You Can Trust

The demand and use of renewable energy continues to rise across the UK. This is also a reason why homeowners and commercial property owners are looking to install solar panels. With long-term savings and environmental benefits, it’s easy to see why. Nevertheless, choosing the right solar installer is crucial to ensure your system is safe, compliant, and built to last.

In this guide, you’ll learn how to identify certified solar installers and the questions you should ask them.

Why Installer Certification is Essential

In the UK, legitimate solar installers are certified under the Microgeneration Certification Scheme (MCS). This scheme ensures installers meet high-quality standards and that systems are eligible for financial incentives like Smart Export Guarantee (SEG).

Another strong mark of trust is accreditation with HIES (Home Insulation & Energy Systems Quality Assured Contractors Scheme). HIES protects consumers through strict standards around fair sales practices, transparent contracts, and robust after-care support. Choosing an installer that is both MCS-certified and HIES-accredited helps safeguard your investment.

Without these certifications, you risk poor installation, voided warranties, and safety hazards.

Qualities of a Trustworthy Solar Installer

Choosing a reputable installer requires more than ticking boxes. Here are qualities you should look for:

• Local Experience – They understand regional regulations, roofing types, and energy needs.
• Transparent Quotes – No hidden fees or vague terms.
• Strong Customer Reviews – Look for consistently high ratings on platforms like Google.
• Integrated Expertise – Companies, such as Kingsley Roofing & Solar, which also specialise in roofing, ensure that your roof can support the system long-term.
• Reliable Aftercare – Good installers offer ongoing support and warranties beyond installation day.

Questions to Ask Before Hiring a Solar Installer

1. What certifications and memberships do you hold?
   Ensure your installer is MCS-certified and ideally HIES accredited. These guarantee quality control, consumer protection, and eligibility for government schemes.
2. Can I see examples of similar projects?
   Reputable companies should be happy to showcase completed projects and provide customer testimonials, especially local ones. It’s a red flag if they refuse.
3. What’s included in the quote? What are the exclusions?
   A good installer provides a clear, itemised quote. This should cover labour, scaffolding, inverters, panels, and electrical components, and specify any exclusions. Watch out for vague quotes that leave room for hidden costs.
4. What warranty is provided on both workmanship and hardware?
   Kingsley Roofing & Solar provides the following warranties:
   — Product warranties (25 years)
   — Linear output warranties (30 years)
   — Workmanship warranties (2 years)
   Kingsley, for instance, provides warranties on both hardware and installation work, offering long-term peace of mind.
5. Who handles permissions and grid connections?
   A professional installer will manage the DNO (District Network Operator) application and make sure your system is connected to the national grid. You shouldn’t have to chase this paperwork yourself.
6. What roofing condition assessments do you perform before installation?
   The condition of your roof directly impacts solar performance and safety. Choose a provider like Kingsley that offers full roofing assessments and repairs where needed before the panels go up.

Common Red Flags to Avoid

1. Pushy Sales Tactics
   Your installer should provide you with options instead of pressuring you to buy immediately. If someone is pushing hard for a deposit before you’ve seen a contract or site plan, walk away.
2. Lack of Written Contracts
   Never agree to verbal agreements. A formal, written contract is essential and should outline timelines, pricing, and responsibilities.
3. No Site Visit or Roof Assessment
   Installers who provide quotes without seeing your roof in person are a major concern. Site-specific factors, such as shading, orientation, and roof condition, must be evaluated in person.
4. Inadequate or Non-Existent Aftercare Plans
   Your solar system should last 25+ years. Make sure the company offers maintenance services and stands behind their work long-term.
