Our accreditations
Accreditations are more than logos. They set expectations for technical quality, accurate proposals, consumer protection and regulated finance conduct.
Scheme scope and eligibility can vary by product and project. REST will confirm the protections that apply within your quotation and contract documents.
Independently verifiable

Protection around the decision
HIES and EPVS address different parts of the customer journey: contractual protection and independent confidence in the numbers used to explain a system.
Contract and payment protection
Independent confidence in the numbers
Always review your quotation, contract, certificates and scheme documents. They confirm which protections apply to the specific installation.
Independent verification
Use the official registers and links above to check membership, permissions and the current scope of each organisation. REST can also explain which certification and protection documents you should receive during your project.
Verify the business name, registration details and relevant work category before relying on a scheme or permission.
Accreditation questions
These answers explain the general purpose of the schemes. Your contract documents should confirm the exact protection attached to your project.
They provide independent standards for technical work, customer information, finance conduct, performance estimates and dispute resolution. The exact protection depends on the scheme and the contracted project.
An MCS certificate, or an accepted equivalent, is normally required by energy suppliers when confirming eligibility for Smart Export Guarantee payments. The supplier also applies its own tariff and metering requirements.
Subject to the scheme rules and the installation being correctly registered, HIES can provide protections relating to deposits, stage payments, insurance-backed guarantees and independent dispute resolution.
EPVS focuses on the processes behind energy-performance, generation and savings calculations. It is intended to reduce incorrect or misleading projections and improve confidence in proposal figures.
REST UK acts as a credit broker, not a lender. Applicable finance activity must follow FCA conduct requirements, and any finance remains subject to status, affordability and lender approval.
Not necessarily. Accreditation scope, product eligibility and available consumer protection can vary. Your quotation, contract and scheme documents should confirm which protections apply to the specific project.
