What makes a good solar installer in Dorchester
With a system lasting 25–30 years, accreditation and install quality matter more than the cheapest quote. Look for MCS certification (required to claim the Smart Export Guarantee), employed (not subcontracted) installers, an insurance-backed guarantee, genuine local knowledge, and honest advice.
Local factors specific to Dorchester
- Historic and listed buildings. As a county town with Roman and Georgian heritage, Dorchester has many conservation areas and listed buildings where panel placement needs care and sometimes consent.
- Rural surroundings. Outlying properties may suit larger or ground-mounted systems, and often have less shading.
- Good Dorset sunlight. Solid annual sunshine hours support strong returns on unshaded roofs.
Questions to ask a Dorchester installer
- Are you MCS certified and will the install be MCS registered?
- Do your own employees do the work, or subcontractors?
- Is the workmanship warranty insurance-backed?
- Have you checked whether my property is listed or in a conservation area?
- Will you tell me honestly if my roof isn’t suitable?
