Lower build costs. Homes that sell themselves.
Geo Flow, the funded heat network from Rendesco. The most cost-effective route to the Future Homes Standard.
A few metres down the ground stays at around 10°C all year, whatever the weather. This steady temperature ensures the heat pumps on our network run at high efficiency regardless of the outside air temperature.
ground temperature, all year
Nothing sits above ground: the chamber where the boreholes meet the network is below the surface, like a drainage inspection chamber.
Heating, hot water and cooling from one unit, as standard.
seasonal efficiency (SCOP)
The same platform gives you visibility through commissioning and handover.
Cooling puts warmth back into the ground, ready for winter.
A funded network costs you less than an air source heat pump on every plot.
Higher efficiency makes energy targets easier to hit.
The heat pump produces efficient and effective cooling as standard.
No outdoor units to fit around façades, boundaries or gardens.
A footprint no bigger than a small fridge freezer.
Lower peak demand can cut connection and infrastructure costs.
Design, drilling, installation, commissioning and support, all Rendesco.
Higher efficiency and a comprehensive servicing and warranty package mean less to pay for heating and hot water.
Full parts and labour.
Every two years, to keep it running efficiently.
Less electricity for the same warmth compared to air source.
No outdoor unit, no fan noise, nothing to steal or damage.
Help any hour, any day.
From the same system, in summer.
Send us details of your new-build site to see the benefits of using Geo Flow.
Using a heat pump means your rooftop solar panels and a home battery can feed it directly.
Our smart controller lets you get the most from time-of-use tariffs, heat pump operation and solar export.
Specified per site: we can advise on panel and battery sizing alongside the network design.

“Such is our confidence with Rendesco, we have recently instructed Rendesco to maintain our air source heat pump sites and conduct all water treatment and testing.”
“I have very much appreciated Rendesco's professionalism, their superior knowledge and their great manner when dealing with our residents. Excellent customer service all round.”
“I wasn't sure a heat pump would suit an older house, but Rendesco proved it. The heat pump and battery, optimised by Flow, cut our bills by 65% (£1,455 a year) and it just works.”
“Rendesco made the switch effortless. With an air source heat pump, battery storage and their Flow optimisation, we're saving 45% (£980 a year) and the house is consistently warm.”
“In the first month the Rendesco Flow system is on track to cut our energy bills by 40% and the house has been warm and comfortable at all times.”
Geo Flow is a funded ground-source heat network for new-build developments. One shared network sits under the site, with a compact heat pump in each home. We design, fund, build and operate it. It is the most cost-effective way to achieve Future Homes Standard compliance.
Yes, Geo Flow is the most cost-effective way to achieve the Future Homes Standard, compared to an air source heat pump on every plot.
Geo Flow costs less than installing an air source heat pump on every plot, and without a noisy unit in the garden, you can build better, more sellable homes. It is the most cost-effective way to achieve the Future Homes Standard. And you and your residents have one accountable partner for the long term.
We do, permanently. The network never transfers to a management company, your buyers or you. The obligations that come with owning it, upkeep, repair, regulation, stay with us too.
We do. We fund the network upfront and recover its cost through a low, steady resident tariff that residents pay over the long term.
Design & Build heat pump projects, delivered with one accountable team.
