Insite Energy works with managing agents, private developers, housing associations and local authorities to create bespoke maintenance contracts that work for their heat networks.

Our engineers and technical team ensure that your network meets the advised CIBSE Heat Networks Code of Practice (CP1) standards as a minimum, and focus on improving efficiencies in order to reduce costs for you and your residents.

Reactive maintenance

If you're looking for a reliable and efficient call-out service, look no further. We have a team of experienced engineers to help you with unexpected breakdowns. They can help you to quickly identify and fix the problem, so you can get your equipment back up and running as soon as possible.

To ensure your heat network runs as efficiently as possible, reactive maintenance is best used in conjunction with a proactive maintenance program.

Planned preventative maintenance (PPM)

Don't wait for a breakdown to occur. Regular maintenance can help prevent costly repairs and downtime and ensure that your heat network is running at optimal performance. With our PPM services, you can have peace of mind knowing that your equipment is in good hands.

 To ensure your heat network runs as efficiently as possible, proactive maintenance is best used in conjunction with a reactive maintenance program.

"The engineer, James, came for a routine maintenance visit today. He was polite, efficient and took the trouble to explain to me what he was doing and how the heating system worked. All in all he was a credit to Insite and I would be more than happy to have him as the engineer for site. Thank you." - Alun Tanner on Trustpilot

ESCo Manager

Insite’s ESCo Manager solution provides everything you need to ensure that your heat network is effectively managed without being tied to long contracts. Services included are the management of meter & billing, fuel procurement, operation & maintenance, financial & legal administration, and reporting & compliance.

Network Efficiency Improvement (NEI) services

When working optimally, heat networks consume less energy than comparable dwellings with conventional gas boilers. However, like any system, heat networks can become less efficient over time, leading to higher energy costs and increased carbon emissions. In a 50-unit development, a 20% efficiency increase can generate savings of £16,121 per year.

In addition to reducing energy costs and carbon emissions, improving the efficiency of a heat network can also lead to improved comfort and reliability for the end-users.
