How do you choose a solar panel installer in Dorset?
Check MCS Certification
Only MCS-certified installers qualify you for the Smart Export Guarantee and 0% VAT on residential installs. Verify your installer on the MCS database. 181 installers serving Dorset are currently certified.
Compare Multiple Quotes
Get at least 2–3 written quotes with itemised breakdowns. A typical 4kWp system in Dorset costs £6,600–£8,500 including 0% VAT. Ensure quotes include panels, inverter, mounting, electrical work, and EPC assessment.
Verify Insurance & Warranties
Confirm public liability insurance and ask about workmanship warranty (minimum 5 years). Panel manufacturers typically offer 25-year performance guarantees and inverters come with 10–12 year warranties.
Read Customer Reviews
Check Google, Trustpilot, and Facebook reviews. Ask for references from recent installations in Dorset. Look for detailed reviews mentioning communication, tidiness, and after-sales support.
Check Equipment Brands
Ask which panel and inverter brands are used. Tier 1 solar panel manufacturers (e.g. JA Solar, Trina, Canadian Solar) offer the most reliable long-term performance. Avoid quotes that don't specify equipment.
Confirm Paperwork Handling
A good installer helps with the DNO notification, MCS certification, and arranges the post-works EPC assessment. Ask whether these are included in the quoted price.
