What is the Energy Technology List?

The Energy Technology List (ETL) is a government-backed database of energy efficient products designed to help UK businesses and public sector organisations make informed purchasing decisions. With energy costs putting pressure on organisations to reduce spending, choosing efficient equipment is an important step towards improving building performance and reducing unnecessary energy consumption. 

The Energy Technology List represents the top 25% of the most energy efficient technology available in the market, providing information about products that meet defined energy efficiency criteria and helping buyers identify suitable technologies and compare available options. This includes building controls, which can play an important role in reducing energy use by improving how heating, ventilation and air conditioning systems operate.  

How does the Energy Technology List work? 

Managed by the Department for Energy Security and Net Zero (DESNZ), the Energy Technology List features around 8,000 products across a range of technology categories. 

Products must meet the relevant energy-performance criteria for their category, with assessment and verification requirements depending on the technology. The list provides product information and performance data to help businesses and public-sector organisations make more informed purchasing decisions. 

This is useful because comparing products based on supplier claims can be difficult. The ETL offers an additional source of independently assessed information, helping decision-makers evaluate eligible products against recognised energy efficient criteria. 

The list covers a range of technology, including heating equipment, building controls and energy management systems. For organisations looking to reduce their energy consumption, it provides a starting point for identifying products that may help improve the energy efficiency of their buildings. 

Why are energy efficient building controls important? 

Replacing older equipment with newer, more efficient technology can improve a building's energy performance. However, the way equipment is controlled also affects how much energy a building uses. Poorly optimised systems waste energy heating empty rooms, warm a room too slowly for it to be beneficial or require manual adjustments to adapt to external temperatures and cold spikes. Even a modern heating system can waste energy if it isn't configured to suit the building, the way it's used and its occupants. 

A Building Energy Management System (BEMS) like HeatingSave can address these problems by coordinating heating with room bookings, occupancy, external temperatures and general building schedules. Building or heating controls can adjust when heating systems turn on, manage target temperatures and respond to changing conditions. This can reduce unnecessary energy use while maintaining comfortable temperatures. 

Is HeatingSave listed on the Energy Technology List? 

In 2025, HeatingSave was the first Building Energy Management System to be added to the Energy Technology List, and its products are listed under the relevant HVAC Building Controls and Building Energy Management Systems categories.  

"HeatingSave is the first Building Energy Management System (BEMS) product added on the ETL in this sub-technology under Energy Monitoring. It is great to see that you are trailblazing and setting the example for other manufacturers to follow suit." - ICF 

Being listed means that HeatingSave's Building Energy Management System complies with strict regulations and specifications, such as the class A functionality requirements from BS EN 15232-1: 2017. The full requirements for Building Energy Management Systems can be seen on the ETL website. 

How can HeatingSave help reduce energy costs? 

HeatingSave's Building Energy Management System is designed to help businesses and public-sector organisations manage their heating, cooling and lighting systems more efficiently. HeatingSave improves how heating, cooling and lighting systems operate, rather than simply relying on fixed schedules or manual adjustments. By combining intelligent control strategies with temperature monitoring and scheduling, the system helps reduce unnecessary energy consumption. 

Depending on the building and its requirements, the system can help organisations: 

• Coordinate heating with building use: Align heating schedules with room bookings and occupancy requirements. 
• Manage temperatures more effectively: Monitor temperatures and control heating to support the occupancy requirements. 
• Reduce unnecessary heating: Avoid heating spaces when they are unused for a period of time. 
• Respond to changing conditions: Adjust heating operation to account for outdoor temperatures and heat-loss profiles.  

These capabilities are particularly useful for businesses and public sector organisations with variably occupied spaces and variable operational times, while providing better visibility and control over existing building systems.  

HeatingSave's controls can coordinate heating with room bookings and building usage, helping avoid heating spaces when they aren't needed. Its heat-loss algorithm also helps manage heating operation in response to a building's thermal behaviour, supporting more effective temperature management.

Case Study: The Coplow Centre cuts gas bills by 51% with HeatingSave 

The Coplow Centre is a multi-purpose community facility in Billesdon, Leicestershire, welcoming more than 24,000 visitors each year. Its facilities include a large events hall, meeting rooms, a lounge and bar, and a professional kitchen. 

Before installing HeatingSave, the Centre struggled to manage its heating efficiently. The main hall took around five hours to warm up before events, rooms were not always heated when needed, and heating was sometimes left running after use. Without centralised controls or energy metering, it was also difficult to identify and address energy waste. 

The centre installed HeatingSave's Building Energy Management System, which was customised to suit the building's requirements. The system coordinates heating with room bookings through a heating diary, adjusts temperatures in response to occupancy, and uses self-learning software to calculate optimal temperatures. It also manages other building systems, including destratification fans, solar panels and air conditioning. 

The Coplow Centre Trustee and Facilities Manager said: 

"We have now had HeatingSave for eight years and have made a 51% saving on our gas bill. One of the biggest savings has been in heating the main hall. We cut by a staggering 90% the time it takes to heat the hall and hence the cost."
