About MCS
MCS (Microgeneration Certification Scheme) is the UK’s national quality mark for small-scale renewable technology, such as solar panels and heat pumps. We’re here to set standards and provide protection, giving consumers confidence to invest in renewable technologies to heat and power their homes and small businesses. Working with industry, MCS defines, maintains, and improves quality, by setting standards for low-carbon energy technology products, contractors, and their installations.
Now is an exciting time to join MCS; especially as we have recently launched the redevelopment of the Scheme, which has a greater focus on consumer protections, quality workmanship, and dispute resolution. 2025 was a record-breaking year for the small-scale renewables industry in terms of installation volumes and we look forward to continuing our vital role in driving forward the UK's progress towards Net Zero.

Complaints Team
The Complaints Team sits at the heart of one of the most ambitious reforms in the history of the MCS Scheme: putting world-class complaints management at the centre of our mission to protect consumers, support installers and transform confidence in small-scale renewables.
MCS is the clear and trusted place for consumers, installers and industry stakeholders to turn to when something goes wrong. Our team has already designed new processes, built strong partnerships with Certification Bodies, and shaped how MCS now oversee the new and improved complaint handling process across the sector.
We are looking for a tenacious investigator, a fair-minded problem-solver, and a genuine champion for consumers and installers. Someone who thrives on complexity, seeks truth, and is driven by making things better, not just case by case, but systemically.
Independent research from Citizens Advice and the Competition & Markets Authority makes clear that consumers in our sector often don’t know where to turn and are passed from pillar to post. Historically, MCS did not handle complaints directly.
As part of the reformed Scheme, MCS is now the central escalation point for any complaint involving an MCS certified installation or installer that has not been resolved by the installer.
This is your opportunity to help shape an entirely new era of accountability, transparency and trust in renewable energy.
What you'll do:
- Demonstrate our principles of good complaint handling.
- Effectively manage your caseload, meeting KPIs and ensuring quality responses, including: consumer complaints , complaints from installers, consumers or manufacturers about MCS or a Certification Body, complaints from whistleblowers
- Champion fair outcomes for both consumers and installers, supporting them to reach appropriate resolutions using an evidence-based approach.
- Identify vexatious, frivolous or bad-faith complaints, applying proportionality and professional judgement.
- Balance consumer protection with MCS’ defined remit, recognising when to act, when to signpost, and when issues fall outside of scope.
- Deliver greater consistency and clearer routes in complaint handling and the outcomes achieved for consumers, realising a significant improvement in the sector’s speed of response and resolution of complaints.
- Adopt a tenacious, investigative approach to complaints, refusing to accept issues at face value and relentlessly digging deeper to uncover the full picture. Challenge assumptions, ask probing questions, and follow every lead to get to the root cause, ensuring that resolutions are based on facts and not just surface-level information.
- Contribute to a culture of awareness and proactive support for consumers in vulnerable circumstances.
- Be able to identify vulnerabilities and adapt communication styles and processes to meet individual needs to support consumers.
- Promote reasonable adjustments to ensure fair and accessible complaint resolution for all consumers.
- Improve transparency and ensure that the original installer is fully engaged and supported in the MCS complaint management process, working in partnership to achieve the right outcome.
- Provide greater oversight of the sector’s complaints landscape and trends both within MCS and externally, helping inform standards and scheme developments that aim to improve the quality of outcomes for consumers.
- Connect complaints with the scheme’s management of an installer’s risk of non-compliance, reducing the likelihood of future complaints.
- Ensure that cases that cannot be resolved and therefore move from complaint to a dispute, are appropriately signposted to our chosen Alternative Dispute Resolution (ADR) provider
- Support the reporting of complaints to the MCS Senior Leadership Team, identifying root causes and areas for improvement, both to MCS operations and the sector in general.
- Communicate with external stakeholders such as DESNZ, Ofgem, Certification Bodies, Consumer Codes, Trading Standards, Citizens Advice and MPs regarding complaints.
- Work closely with your colleagues across the wider Customer Experience team to create a seamless consumer journey
Main role and responsibilities:
One of the most significant reforms to the MCS certification scheme, has been centralising of complaints management for the sector. Previously MCS have not dealt with complaints directly and have signposted to other organisations including Certification Bodies and Consumer Codes. This has now changed as MCS has become the place to escalate any complaint relating to an MCS certified installation or installer, that the installer has not resolved.
We’re now therefore looking for an inspiring, investigative consumer champion and complaints resolution specialist, who can help us to deliver on our goal of simplifying the complaints landscape.
The Complaints Resolution Team is responsible for embedding complaint management at the heart of our scheme, helping to ensure we deliver on our mission to give people confidence in low-carbon energy technology.
