Accreditations & Memberships

The Microgeneration Certification Scheme (MCS) is the recognised benchmark for renewable electricity systems and the installers who fit them, assessing the supply, design and installation of every system against rigorous technical standards. Our MCS accreditation means our solar PV and battery work is independently audited, not self-certified.

For you, MCS certification is the gateway to grant eligibility and documented assurance that the system was specified to a recognised standard. You can check any MCS certified installer directly on the MCS register.

TrustMark is the only government endorsed quality scheme for work carried out in and around your property. As a TrustMark registered installer, we are vetted on technical competence, trading standards and customer service, and reassessed regularly to keep our registration in place rather than holding it indefinitely.

For commercial clients it adds a layer of protection most contractors cannot offer: a clear complaints route, work that meets the scheme's customer charter, and financial protection should anything go wrong during the guarantee period. You can confirm our registration directly on the TrustMark website.

NAPIT is one of the UK's leading competent person schemes for electrical work. Our NAPIT membership confirms our electrical installations are inspected against current wiring regulations and self-certified compliant under building regulations.

For solar PV, EV charging and battery storage, that matters: the electrical side of a renewable system is where shortcuts cause the most expensive problems. NAPIT keeps that work accountable.

Solar Energy UK is the national trade association for the solar and energy storage industry. Our membership keeps us aligned with the body that sets best practice for commercial solar and represents the sector on standards and policy.

It signals that we work to the industry's agreed code of conduct, and that we stay current as commercial solar technology and regulation continue to move.

Constructionline is the UK's largest register of pre-qualified contractors, used by public bodies and large commercial buyers to vet their supply chain. Our Constructionline accreditation confirms we have passed checks on health and safety, insurance, finance and environmental policy.

For local authorities, housing associations and larger procurement teams, it means the due diligence is already done. We meet the standards your tender process is built to test for.

SSIP (Safety Schemes in Procurement) is the umbrella body recognised across UK construction for health and safety pre-qualification. Our SSIP accreditation shows our safety management has been assessed to a standard buyers accept without a second audit.

It removes a common hold-up on commercial sites: when your principal contractor or procurement team asks for health and safety evidence, ours is already verified and ready.

InspireGreen is an Octopus Trusted Partner. This means Octopus Energy has selected and vetted us as an independent installer, and continues to monitor our work against its standards for quality and customer service.

Independent companies selected, vetted and monitored by Octopus Energy against safety, quality and customer-service standards. Not Octopus employees.

SQMAS (Supplier Quality Management Audit Scheme) is a quality management standard built for small and medium businesses as a practical alternative to ISO 9001. It works to the same core principles but is assessed against a shorter set of requirements suited to a business of our size. Our SQMAS accreditation means our quality management has been audited by an independent third party and is re-inspected every year.

For public sector and commercial buyers, it answers a question that comes up in most tenders and pre-qualification questionnaires: can you show an independently audited quality system? It confirms that the way we run a job, from first enquiry through to sign-off, has been checked by someone other than us.

ISO 9001 is the international standard for quality management systems. It sets out how a business should plan, run and review its work so that quality is managed by a defined system rather than left to individuals. Our ISO 9001 certification means the way we handle a project, from first enquiry through to sign-off, has been documented and independently audited against that standard, with a review each year to keep the certification in place.

For commercial and public sector clients, it shows there is a recorded process behind the work. If something needs correcting on a job, there is a defined way to catch it and act on it, and an external auditor checks each year that we are following it.

ISO 14001 is the international standard for environmental management systems. It sets out how a business identifies the environmental impacts of its operations and manages them, with a requirement to keep improving over time. Our ISO 14001 certification means we have that system in place and have been independently audited against the standard, with the certification reviewed each year.

For a renewable energy installer it puts our own operation under the same kind of scrutiny we help clients apply to theirs. For buyers it is recognised evidence that environmental management is run to a defined standard and checked by someone outside the business.

Green Business certification is independent third-party validation of a company's environmental management system, with a review process scaled for smaller businesses. Our certification confirms that InspireGreen holds a clear environmental policy and an action plan covering the significant environmental impacts of running the business, reviewed by an independent assessor. It is awarded for twelve months and renewed each year on evidence that we are still reducing those impacts.

For a renewable energy installer, it sets a standard we apply to our own operation and not only to the systems we design for clients. It means the way we manage our environmental impact has been checked by someone other than us, and that we have to show real progress each year to keep the certification in place. You can read what the scheme involves on the Green Business website.
