Every certification we hold is a promise to you — that our work meets the most rigorous quality, safety, and environmental standards in the UK renewable energy sector.
We hold every key certification required by UK law and industry best practice — giving you complete peace of mind.
MCS is the UK's quality mark for small-scale renewable installations. MCS certification is legally required to claim Smart Export Guarantee (SEG) payments and government incentives. Our MCS number ensures every installation meets the highest technical standards.
TrustMark is the UK Government's quality endorsement scheme for tradespeople. As a TrustMark member, we are regularly inspected and assessed for quality of work, customer service and trading practices — giving you additional consumer protection.
ISO 9001 is the world's most recognised quality management standard. Our certification demonstrates our commitment to consistent, high-quality processes across every aspect of our business — from customer enquiry to post-installation aftercare.
ISO 14001 certifies our environmental management commitments. We operate with minimal environmental impact throughout our supply chain and installation processes — consistent with our core mission to protect the planet.
NAPIT registration means our electricians are fully competent, regularly assessed and can self-certify electrical work to BS 7671. All our wiring and electrical installations comply with current IET Wiring Regulations.
As a RECC member, we adhere to a strict consumer protection code covering sales practices, contracts, deposits, and dispute resolution — giving you additional rights and protections beyond standard consumer law.
Installing solar or battery storage is a significant investment. These certifications are your guarantee that Sunline Energy has been independently assessed, meets all legal requirements, and will be held accountable to the highest standards.
MCS certification is required for Smart Export Guarantee (SEG) payments and most government solar schemes. Without it, your installer cannot legally register your system.
Most mortgage lenders and home insurance providers require MCS certification documentation before covering solar installations. We provide all necessary paperwork at handover.
RECC membership gives you additional consumer rights, including independent dispute resolution if any issues arise — something unregistered installers cannot offer.
Unlike uncertified installers who self-declare quality, our work is independently audited by third-party assessors on a regular basis.
Our certifications aren't just paperwork — they're reflected in the quality of every installation and the satisfaction of every customer.
Every Sunline Energy installation is fully certified, guaranteed, and backed by the UK's most comprehensive set of trade accreditations.
