KURVE, the UK’s first digital pay-as-you-go (PAYG) web-app for heat networks, has delivered significant savings on the capital cost of energy metering at Greenside Views, a newly completed development made up of one, two and three-bedroom flats in Mitcham, Southwest London. Greenside Views is the first KURVE site to go live, following its announcement last year.
The managing agent, Lotus Trident, was presented with three PAYG options: KURVE and two in-home display-dependent solutions. KURVE achieved an average saving, covering installation and hardware, of 60% or £33,000 compared to the alternatives and was chosen as the preferred solution for the 89-unit development.
KURVE is the fruit of a joint venture between heat network metering and billing specialist, Insite Energy, and SAV Systems, provider of low carbon, energy efficient heating solutions. It is designed to make smart metering more accessible for heat network users, to reduce costs and improve their access to consumption data. The cost of installation and hardware is a major barrier discouraging the up-take of PAYG smart meters by housing providers operating heat networks, even though individual heat meters are now a legal requirement in most instances.
“The savings are genuinely impressive. There is no trade-off with taking the more affordable option as one might normally expect,” said Arjun Shah of Lotus Trident. “Not having to fit hard-wired in-home displays is a huge advantage and we’re getting a great level of energy data. The real value to residents lies in the fact they can easily access their energy usage data and manage their account anywhere, from any internet device. It’s transparent, straightforward, and convenient. In the first few weeks since KURVE was implemented, I’m pleased to say it has gone very smoothly with no issues.”
“When we talk about the potential savings KURVE offers, people want to see operational evidence,” commented Ellie Blacklock, KURVE Project Manager at Insite Energy. “It’s therefore great to now see sites, owned and managed by housing associations and local authorities, as well as private developers and landlords, going live and reaping the benefits of KURVE.”
Insite Energy and SAV Systems’ clients and stakeholders from across the UK heat network market had repeatedly called for a low-cost PAYG product that does not compromise on service, quality, or convenience to the end-user, and at the same time can help eradicate energy debt risk for housing providers without the need to make large investments in metering hardware.

Launched in November 2019, KURVE is the UK’s first digital app-based metering solution for heat networks. Kurve Technologies is a collaboration between industry specialists, Insite Energy and SAV Systems. KURVE is designed to transform energy metering, billing, and payments with a system that is more affordable, flexible, functional, easy to install and cheaper to run than established pay-as-you (PAYG) alternatives.
KURVE’s streamlined package combines a Kamstrup energy meter, prepayment valve, heat interface unit (HIU) from SAV or other provider, and a Kamstrup Master Multiport. The KURVE install is pre-wired and does not require an in-home display device. KURVE’s design not only cuts time spent on installation and commissioning, it also significantly reduces service, maintenance and administration costs compared to other PAYG alternatives. KURVE is estimated to deliver a combined CapEx and OpEx saving of around 56%, relative to competitor metering solutions. Billing costs are estimated to be reduced by 17%. Coming largely as a result of the system’s smart Mbus infrastructure, a standard network set-up enhanced for two-way communication, these OpEx savings can be passed on to residential customers via their heat tariffs – an area which is increasingly under the microscope of consumer watchdogs.
For just a few pounds a year, heat network operators specifying KURVE will gain access to data diagnostics including energy consumption and VWART (Volume Weighted Average Return Temperature) from each connected meter. Analysis of this detailed data provides valuable insight into usage patterns and enables operators to optimise network performance, improve efficiencies, and reduce costs through to the end-user. This functionality has only been available previously with premium prepayment metering solutions which have proven to be out-of-reach to low-cost developments outside of the London market.
