Solar Installer Accreditations Scotland — Complete Guide
A fully compliant solar installer in Scotland holds seven accreditations: MCS, RECC, HES, an electrical competency certification (NICEIC, NAPIT, or SELECT), and HIES. This guide explains every one, who needs it, and how to verify it. Scottish Energy Efficiency holds all of them.

MCS Certified
MOST CRITICALMicrogeneration Certification Scheme
MCS certification is the foundation of a compliant renewable energy installation in Scotland. It certifies the installer, the products used, and the installation itself. MCS is required for all HES grants, ECO4 funding, and Smart Export Guarantee registration. Without a valid MCS certificate, no grant scheme or SEG payment is accessible.
Key Requirements and Benefits
- Required for HES heat pump grant (up to £7,500)
- Required for ECO4 funding
- Required for Smart Export Guarantee registration
- Certifies the installer, the products, and the installation
- Installer and products both must be MCS approved
- Generates a unique installation certificate per job
- Installer must be certified at time of installation
- Renewed annually — verify current status
Who Needs It
Every installer of solar PV, heat pumps, and other renewable technologies must hold MCS certification to access grants and register for SEG.
How to Verify
RECC Registered
Renewable Energy Consumer Code
RECC membership provides consumer protection that no other accreditation offers. Deposit protection if the installer fails, a binding complaints process with access to ADR, and guaranteed cancellation rights all apply exclusively through RECC registered installers. Home Energy Scotland expects RECC membership for approved installers.
Key Requirements and Benefits
- Deposit protected if installer goes out of business
- Access to independent Alternative Dispute Resolution
- Cancellation rights enforced under the code
- Audited against the Renewable Energy Consumer Code
- No high-pressure or misleading sales tactics permitted
- Written quote and contract required before signing
- Aftercare obligations under the code
- Expected by Home Energy Scotland
Who Needs It
Domestic renewable energy installers who sell direct to homeowners should hold RECC membership as a minimum consumer protection standard.
How to Verify
HES Registered
Home Energy Scotland Approved Installer
HES registration allows the installer to handle Home Energy Scotland grant applications on your behalf. Without an HES registered installer, the £7,500 heat pump grant (or £9,000 rural uplift) cannot be accessed. The installer manages the full application — eligibility check, technical documentation, submission, and approval.
Key Requirements and Benefits
- Required to access HES heat pump grant (£7,500 standard)
- Rural uplift to £9,000 also requires HES registration
- Handles full application end-to-end on your behalf
- Conducts eligibility and rural uplift check
- Produces required technical documentation
- Manages direct relationship with Energy Saving Trust
- Grant approved before installation begins
- Requires MCS certification as a prerequisite
Who Needs It
Any installer wishing to handle HES heat pump grant applications on behalf of customers must be registered with Home Energy Scotland.
How to Verify
NICEIC Accredited
National Inspection Council for Electrical Installation Contracting
All solar installations involve electrical work. The inverter installation, AC wiring, consumer unit connection, and grid connection all require a competent electrician. NICEIC accreditation is one of the primary electrical competency schemes in the UK, allowing self-certification of electrical work without requiring local authority sign-off.
Key Requirements and Benefits
- Covers all electrical installation work
- Covers inverter installation and AC connections
- Covers consumer unit and main electrical connections
- Enables self-certification under Part P (England/Wales)
- Audited against IET Wiring Regulations
- Insurance backed
- Work covered by NICEIC guarantee
Who Needs It
Any installer or electrician carrying out electrical work — including inverter installation and grid connection — must hold an electrical competency accreditation.
How to Verify
NAPIT Accredited
National Association of Professional Inspectors and Testers
NAPIT is an approved competent person scheme for electrical work, renewable energy, and building services. It is broadly equivalent to NICEIC in terms of electrical competency scope. Some solar installers hold NAPIT rather than NICEIC — both are acceptable. In Scotland, SELECT is the primary equivalent.
Key Requirements and Benefits
- Approved competent person scheme
- Covers renewable energy installations including solar PV
- Electrical installation self-certification enabled
- Audited against wiring regulations
- Alternative to NICEIC for electrical sign-off
- Some MCS installers hold NAPIT rather than NICEIC
Who Needs It
Electricians and solar installers in England and Wales who want an alternative to NICEIC for electrical competency accreditation.
How to Verify
SELECT Accredited
SCOTLAND SPECIFICElectrical Contractors Association of Scotland
SELECT is the Scottish equivalent of NICEIC and NAPIT. It is the primary electrical competency body for contractors working in Scotland and is recognised by local authorities and building standards bodies across Scotland. SELECT accredited electricians can self-certify electrical installation work in accordance with Scottish building regulations.
Key Requirements and Benefits
- Primary electrical competency body for Scotland
- Recognised by Scottish local authorities
- Covers solar PV electrical installation work
- Self-certification of electrical work in Scotland
- Audited against BS7671 and Scottish Building Standards
- Preferred for Scottish installations over NICEIC
- SELECT Approved membership searchable publicly
Who Needs It
Electricians and solar installers based in Scotland who want Scottish-specific electrical competency accreditation.
How to Verify
HIES Member
Home Insulation & Energy Systems Quality Assured Contractors Scheme
HIES (Home Insulation & Energy Systems) is a consumer protection scheme similar in principle to RECC. It provides deposit protection, a complaints process, and access to dispute resolution for consumers who purchase from HIES member installers. Some installers hold both RECC and HIES membership. RECC is more commonly expected in the renewable energy sector.
Key Requirements and Benefits
- Consumer protection scheme for home energy products
- Deposit protection for consumers
- Complaints process and dispute resolution
- Similar in scope to RECC
- Some installers hold both RECC and HIES
- RECC is more commonly required for solar and heat pumps
- Searchable at hiesscheme.org.uk
Who Needs It
Installers offering home improvement and energy systems products who want additional consumer protection scheme coverage beyond RECC.

The Complete Picture
Why All Accreditations Matter Together
Each accreditation covers a different aspect of the installation process. MCS ensures technical quality and grant eligibility. RECC protects your money and consumer rights. HES registration enables grant access. Electrical competency ensures safe, certified grid connection. HIES provides an additional consumer protection layer.
Missing any one creates a gap. An MCS certified installer who is not RECC registered leaves your deposit unprotected. An MCS and RECC registered installer who does not hold SELECT accreditation may not be able to self-certify the electrical work in Scotland. An HES registered installer who fails to handle G99 properly may create legal export issues that block SEG.
The safest approach is to use an installer who holds all relevant accreditations. This removes every potential gap in quality, compliance, consumer protection, and grant access. It also significantly simplifies the property sale disclosure process — a single installer with complete documentation is far easier to evidence than multiple partial providers.
Always verify accreditations at the time of contract — not just at first enquiry
MCS certification lapses, RECC memberships expire, and HES registration can be withdrawn. An installer who was fully accredited when you first contacted them may not be by the time you sign. Verify everything in writing immediately before signing.
