By ensuring comprehensive and clear documentation, FairHeat helps operators maintain efficient and compliant heat networks while minimising operational risks

When a new site is adopted into a heat network portfolio, or when limited information is available about an existing site, it is critical to establish a clear operational baseline to ensure effective maintenance, regulatory compliance, and long-term efficiency. FairHeat’s Site Onboarding Assessment provides operators with a structured evaluation of the site’s condition, performance, and compliance status, allowing for proactive management and risk mitigation.

Our Site Onboarding Assessment ensures that the key operational and compliance requirements are in place, helping operators manage their networks effectively:

KPI Management

• Identifying and defining Key Performance Indicators (KPIs) to measure site efficiency, reliability, and service quality.
• Establishing benchmarking metrics to track operational performance over time.

Asset Register & Condition Surveys

• Conducting on-site inspections to document the condition of all critical assets, including plant rooms, distribution networks, and consumer connections.
• Developing an asset register to provide operators with a clear inventory of heat network infrastructure.
• Identifying immediate and long-term maintenance needs, preventing unexpected failures.

Regulatory Readiness

• Assessing the site’s alignment with regulatory requirements, such as HNTAS.
• Identifying compliance gaps and providing actionable recommendations to address any deficiencies.
• Ensuring record-keeping and documentation practices meet industry standards.

FairHeat’s Site Onboarding Assessment provides heat network operators with a clear understanding of their assets, risks, and compliance status, ensuring that critical requirements are in place from day one. By identifying areas of concern early, operators can take proactive action to improve maintenance strategies, operational efficiency, and long-term asset performance.

Clients often spend a significant amount of cost and management time dealing with the consequences of poor maintenance of heat networks during the defects and liability period (DLP).

A lack of clear ownership of duties and responsibilities when ownership is transferred between the construction and operation stages can lead to O&M duties not being adequately fulfilled, equipment warranties being voided, and defects not being identified and actioned within the DLP, exposing the heat network owner to a significant amount of ongoing risk.

FairHeat ensure a satisfactory handover to the operation and maintenance teams has been undertaken, and reviews the O&M activities for the plantroom, network and dwellings over the first year of operation, with the aim being to ensure that systems are properly maintained, with correct operating conditions (e.g., water quality and controls) at the point of transfer to the entity taking on the ongoing responsibility for the system.

FairHeat review results and flag any issues for the developer to follow-up on. FairHeat also plots results over time to show trends, which are included in the evidence pack. There is a final inspection of plant room and network carried out by FairHeat at end of the DLP. Final inspection/witnessing identifies any complications that require resolution before the end of the DLP and production of an “evidence pack” to support satisfactory hand over.

Heat tariffs are often not correctly set and do not have an appropriate tariff structure. Often schemes do not recover initial costs through a connection fee and the operational costs through the tariff. Heat tariffs are often unfairly set with respect to usage and do not incentivise good performance. For New Build and Operational sites, FairHeat can provide:

• Review current tariff structure and propose alternative approach based upon client requirements (recoup costs, profit margin, etc.)
• Develop and calculate standing charges for heat network to cover M&B charges, share of utility standing charges, administrative costs and bad debt provisions
• Develop and calculate availability charge for heat network (system O&M costs, heat losses, as required)
• Develop and calculate usage charge for heat network (variable kWh and/or variable volume charges, as required)

Excessive heat loss can lead to higher operational costs, inefficient performance, and customer dissatisfaction. FairHeat conducts detailed heat loss assessments to identify where energy is being wasted and provide solutions to improve system efficiency and cost-effectiveness.

• Thermal analysis of distribution networks to pinpoint heat loss hotspots.
• Evaluating insulation quality and identifying areas for improvement.
• Providing remedial recommendations to reduce heat loss and improve network efficiency.
• Supporting compliance with regulatory efficiency standards, such as HNTAS.

Reducing heat loss is key to improving energy efficiency and lowering operational costs for heat network operators.

A proactive risk management approach ensures system resilience, cost control, and operational stability.

With energy utility costs soaring in recent years, failure to accurately predict a heat network’s gas and electricity consumption can lead to high tariffs, which will drive up the cost of heat to operators and consumers. FairHeat helps clients secure competitive rates by accurately forecasting energy needs and advising on procurement strategies.

• Analysing historical consumption data or comparing similar sites to forecast future demand.
• Assessing peak loads and heat consumption patterns to support procurement decisions.
• Helping clients communicate accurate requirements to energy brokers or procurement teams.

Optimising utility procurement helps operators reduce costs, improve budgeting accuracy, and ensure reliable energy supply.

FairHeat provides a range of services to support network operators maintain and raise the operational performance of its district heating assets, including:

Energy Centre Decarbonisation: The “day one” energy strategy is unlikely to be the only strategy a client’s network needs to deliver. FH can provide strategic advice, develop business cases and undertake detailed design development to facilitate additional decarbonisation of exiting heating supply or sleeving of low carbon heat to new and existing customers.

Network expansion: Networks are growth assets that are expanded over many years post initial operation. FH can provide constraint analysis, identification, intervention and business case development to enable expansion of existing assets to serve new customers.

Ongoing performance monitoring: Any networks core profitability resides in its operational costs vs. its revenues. Keeping these operational costs low is a core and complex activity. We provide remote and in person monitoring of energy centres, building operation and water quality results, identification of inefficiencies, early fault detection, and optimised performance.

Whilst each project is unique, our expertise across engineering solutions, techno-economic modelling, business case development, enables FairHeat to support clients enhance the asset value of their district heating systems.

For existing heat networks, ongoing maintenance and integrity management are essential to preventing network degradation and failure, and delivering an efficient and cost-effective service.

Many operators struggle with poor change management and documentation, unpredictable spend due to unplanned failures, and rising operational costs as sites rapidly worsen as a result of poor maintenance.

FairHeat offers a comprehensive suite of services, ensuring networks are properly managed, financially sustainable, and fully compliant with legislative and regulatory requirements. Our asset management support ranges from reviewing the effectiveness of existing maintenance practices and recommending changes to the incumbent O&M provider; all the way through to the complete management of the heat network through our trusted maintenance partners.
