The MCS Scheme Redevelopment: What It Means for Already-Certified Installers
🔍 Key takeaways
- The redeveloped MCS installer Scheme rolls out across 2026 and into 2027, replacing the current framework.
- It shifts the emphasis from paperwork to evidence of real installation quality and consumer protection.
- Existing certification stays valid, but every business adopts the new Installer Operating Requirements.
- Three named roles become mandatory: Licensee, Main Contact and Technical Supervisor.
- Certification bodies migrate businesses in phases; MCS aimed to reach every installer by June 2026.
- Digital planning and documentation tools cut the admin of evidencing compliance.
What is the redeveloped MCS installer Scheme?
The redeveloped installer Scheme is MCS’s rebuilt framework for certifying renewable energy installers, rolling out across 2026 and into 2027. It replaces a system many installers found admin-heavy with one built around installation quality, consumer protection and a direct relationship between MCS and each business.
What changes for installers who are already certified?
- Evidence replaces box-ticking: The Scheme asks installers to capture proof that their processes work in practice, rather than keeping documentation for its own sake.
- A direct agreement with MCS: Each business signs an Installer Agreement through a named Licensee.
- The MCS Customer Commitment: Consumer Code membership is no longer automatically mandatory. Consumer-protection duties now sit in the MCS Customer Commitment.
- Financial protection: Installers must offer an approved financial protection product.
What are the three new business roles you must assign?
| Role | Replaces | Core responsibility |
|---|---|---|
| Licensee | New role | Signs the Installer Agreement and carries ultimate responsibility for meeting Scheme requirements. |
| Main Contact | Nominee | Single point of contact between the business, its certification body and MCS. |
| Technical Supervisor | Nominated Technical Person | Confirms each installation meets the relevant MCS standards; must hold an in-date qualification for that technology. |
When and how do certified installers move over?
Installers do not switch all at once. Certification bodies migrate businesses onto the redeveloped Scheme in a phased approach across 2026 and into 2027. MCS aimed to have contacted every certified installer by June 2026. The move begins with an onboarding call, where the business confirms its Licensee and works through the new requirements.
How can installers prepare and cut the admin at the same time?
- Get the design right and recorded: Accurate heat loss calculation to the MCS method is the foundation of a compliant heat pump design.
- Digitise site and commissioning records: Structured construction documentation captures photos, sign-offs and commissioning data against each job.
- Standardise your quality processes: Digital checks and forms turn the Installer Operating Requirements into repeatable steps.
Conclusion: The badge stays, the proof behind it changes
The redeveloped Scheme does not take certification away; it raises what certification has to prove. Certified businesses should name their Licensee, Main Contact and Technical Supervisor now and prepare before their certification body calls.

💬 FAQs
Does my current MCS certification stay valid during the transition?
Yes, existing certification remains valid while certification bodies migrate businesses onto the redeveloped Scheme across 2026 and into 2027.
Do I need to reapply to become MCS certified?
No, the redevelopment is a transition, not a fresh application. Your certification body contacts you, confirms your new roles and Installer Agreement, and moves your existing record onto the new framework.
Can one person hold more than one of the three roles?
Yes, one individual can hold multiple roles. Larger businesses installing several technologies may need more than one Technical Supervisor.
What qualifications does a Technical Supervisor need?
An in-date qualification or an in-date ISO/IEC 17024 personnel certification for that technology. Their full name is entered on the MCS certificate in the MCS Installations Database.
Is Consumer Code membership still required?
Not automatically. Consumer-protection duties now sit in the MCS Customer Commitment, which the business signs directly.
Will the changes affect my access to the Boiler Upgrade Scheme?
Staying compliant with the redeveloped requirements keeps grant access intact.
