Redeveloped Installer Scheme

MCS is changing

The redeveloped installer Scheme is based on the feedback we have received from the sector and the extensive response we received on a public consultation we ran in 2023 on the redeveloped Scheme proposals.

Throughout 2025 and into 2026, there will be a rolling transition during 2025 and 2026 as installers are moved across to the redeveloped Scheme.

What is the redeveloped Scheme?

The changes we’re making to our Installer Scheme will help to drive quality in the renewables sector and give everyone more confidence in home-grown energy.

Consumer protection is at the heart of this. We’re overhauling how we work with installers to deliver quality installations to consumers, from centralising complaints management to introducing a brand-new document – the Customer Commitment – which outlines an installer’s responsibilities to protect consumers and adhere to consumer protection laws.

We’re also introducing a range of changes that will impact an installer’s experience with MCS. A risk-based surveillance model will determine how frequently an installer is assessed. There will also be a greater focus on ‘delivered quality’ to consumers, and crucially, MCS will now hold a direct agreement with installers through a new Installer Agreement.

Redeveloped Installer Scheme Structure

The redeveloped Scheme will change the way that MCS, installers, and certification bodies interact. Ahead of transitioning over to the redeveloped Scheme, installers should familiarise themselves with the updated structure and associated documentation, which you will find in the next section.

Core Scheme Documents

Installer Operating Requirements

The framework for how you’ll maintain MCS certification. It outlines the requirements and processes that you need to follow.

MCS Installation Standards

The technical Standards for how systems should be designed and installed. The technical requirements aren’t changing from what is contained in the MCS Installation Standards today, but they have been restructured and streamlined to be more focussed as “technical truths”.

Pre-sale Information and System Performance Estimate Standards

The documents outline how to carry out system performance estimates and the pre-sale information that must be provided to a customer for an installation. These requirements exist today, but we’ve restructured and streamlined into their own technology-specific standards to improve clarity.
