The UK's heat network sector has launched into a new era of regulation. After years of operating with limited, inconsistent consumer protections, the market is now moving under Ofgem's regulatory framework, with the Energy Ombudsman acting as the statutory redress scheme for all heat network consumers.
Over the last few months, a series of reports from the Energy Ombudsman, Citizens Advice, Consumer Scotland and Ofgem have been sharing and developing insights into the challenges and opportunities across heat networks. There is strong support for heat networks as a key part of the UK's decarbonisation journey, but there remain significant challenges around billing transparency, customer service, accountability and consumer trust.
For operators, suppliers, housing associations and managing agents, the message is clear: regulation is no longer something to prepare for in the future. It is here now and Sycous is here to help.
What the Energy Ombudsman has told us
The Energy Ombudsman's first annual review offers one of the clearest pictures yet of consumer experience in the regulated heat network market. During its first year as the statutory redress scheme, it accepted 232 complaints for investigation, with 70% ultimately upheld.
The key themes will be familiar to anyone working in the sector:
Customer service failures
Billing disputes
Supply interruptions and outages
Pricing concerns
Poor complaint handling processes
The Energy Ombudsman report notes that many complaints begin as simple enquiries before escalating because consumers feel ignored, poorly informed or unable to get clear answers.
This highlights an important reality of heat network regulation: compliance is not just about technical performance. It is increasingly about transparency, communication and governance. Sycous focusses on providing market leading compliance support for heat suppliers, building and sharing best practices from across the industry alongside mandatory compliance requirements.
The challenge of hidden debt
Alongside the Ombudsman's findings, Citizens Advice's recent report, Hidden Debt, Hidden Risks, raises concerns about consumers who may not fully benefit from the new protections being introduced.
The report focuses on "bundled" charging arrangements, where heating costs are included within rent or service charges rather than billed separately.
According to Citizens Advice, around one third of heat network consumers currently pay this way.
Their research identifies several risks:
Heating debt becoming hidden within rent or service charge arrears
Consumers facing weaker protections against back-billing
Greater exposure to retrospective price increases
Reduced transparency around charges and consumption
More complex complaint and redress pathways
Whether or not organisations agree with all of Citizens Advice's conclusions, the report highlights the growing expectation that consumer outcomes, not just regulatory compliance, will be scrutinised. Charges may be included in this manner due to leases, supply agreements or other reasons but the idea of splitting out charges, increasing fairness and fairness, especially with mySycous managed credit billing and PAYG provides a viable alternative, with complete transitional support for you as the supplier and your customers.
Consumer trust remains a critical issue
Recent research from both Ofgem and Consumer Scotland reinforces this broader theme.
Consumers consistently report concerns around:
Understanding what they are being charged
Knowing who is responsible when issues arise
Accessing information about their network
Confidence in complaint resolution processes
Perceived value for money
As heat networks become a larger part of the UK's heating strategy, these issues matter. At Sycous we have focussed on addressing these concerns, building our consumer confidence strategy, engaging with heat suppliers as part of our compliance support and supporting proactive engagement with your customers.
The upcoming major milestone: Ofgem registration!
While organisations continue adapting to new consumer protection requirements, another significant deadline is fast approaching.
All heat network operators and suppliers operating under deemed authorisation must register via Ofgem's digital registration service by 27th January 2027.
The Energy Ombudsman highlighted that many suppliers remain uncertain about regulatory requirements and onboarding processes, particularly organisations for whom heat networks are only a small part of their overall business.
This is where many organisations face a challenge:
Understanding which obligations apply
Identifying the required organisational data
Establishing compliant complaints handling procedures
Ensuring consumer communications meet regulatory expectations
Preparing for future assurance and performance requirements
How Sycous can help
At Sycous, we've seen first-hand that heat suppliers are often not struggling with a lack of willingness to comply. They are struggling with complexity.
Heat network regulation is no longer coming. It is already here. The heat suppliers that succeed will not simply be those that comply with the rules, but those that use regulation as a catalyst to improve customer outcomes, build trust and strengthen their operations. With key milestones approaching, there has never been a better time to review your readiness. Sycous, our Compliance Team and our wider team can help:
Prepare for Ofgem registration requirements
Review complaints and redress arrangements
Assess customer journey and communication processes
Strengthen compliance frameworks
Improve governance and accountability
Build confidence ahead of future regulatory milestones, including Heat Network Technical Assurance Scheme (HNTAS)
We help heat suppliers move beyond a "minimum compliance" approach towards building more resilient, consumer-focused heat network operations, ingrained throughout our service offerings.
Looking ahead
The latest reports send a consistent message, we are moving in the right direction, but there is still significant work to do.
Thriving in this regulatory environment is about more than meeting deadlines, taking the opportunity to strengthen customer trust, improve transparency and embed good governance throughout their operations.
