What Makes Us Different
Proud to becertified
For Arc Line Design, trust and the quality of our work means everything to us, which is why we are proud to be certified by the Microgeneration Certification Scheme (MCS) - a quality‑assurance scheme for small-scale, low‑carbon energy systems—like solar panels, heat pumps, and batteries in the UK.
Why does this matter to you? By being MCS certified, it means we have been independently assessed against strict technical, safety, and quality standards. The products we use (such as solar panels) meet rigorous testing standards and our installation work is regularly assessed to ensure technical competence and quality.
But we don't stop there. Here at Arc Line Design we pride ourselves on being transparent and fair, and as a result, have built on the minimum standards of our MCS certification to put our customers needs at the heart of what we do.
