Get up to £2,600 of benefits for energy efficiency

Get up to £2,600 of benefits for energy efficiency

We are looking to facilitate energy efficiency improvements as part of a government project.

There will be a number of additional benefits for the first one hundred properties to take part in the project including:

  • Discounts on improvements of up to £1,600
  • Free smart home devices worth up to £1,000
  • A free post-improvement Energy Performance Certificate (EPC) worth £79.

We’re especially looking to get properties to at least an energy rating of C (and above) and ideally off gas heating.

This project is funded by Innovate UK’s Small Business Research Initiative (SBRI) under the Net Zero Heat programme.

What's on offer?

Discounts on improvements

Through our suppliers you’ll get:

  • £700 off solar panels
  • £700 off a heat pump
  • £200 off each battery

Free smart home environmental sensors

Over £600 of AICO Homelink smart home environmental monitoring sensors with installation. Aico Homelink are a market leader in smart home insights.

See insights into heat loss, indoor air quality, and condensation, damp and mould risks amongst others.

You can also see temperature, humidity, CO2 and energy data.

This smart home solution consists of a gateway and three environmental sensors

A free smart thermostat

For ten homes we’ll also include a Drayton Wiser smart thermostat with two TRVs for individual room temperature controls, plus installation. 

Drayton is a market leader in thermostatic controls.

This package is worth nearly £400.

A free EPC

After improvements have been complete you’ll get a new Energy Performance Certificate (EPC) worth £79.

Frequently asked questions

Am I guaranteed to be selected?

No, if there are more than one hundred applicants we will prioritise based on balancing our sample size and those that will have the most impact.

What’s the commitment?

You will need to commit the project terms and conditions (found here) which will include allowing smart home data and smart meter access for a year from installation so we can measure the impact of the improvements.

We may publish anonymised data as part of the project results and may share impact insights with the partner you accessed the service from (for example with your lender for verification the works took place).

What about the remaining cost of the improvements?

You will need to pay the remaining balance either through savings or financing.

As part of the project we will also review grants and lender incentives so see if the cost can be reduced further.

Do I need a smart meter?

Ideally yes, but we can accept applications without smart meters.

Can I keep all smart home devices?


Can I buy more smart home devices?

If you require additional sensors or smart TRVs let us know and we can take payment and include these in the order.

Do I need to get all improvements from your suppliers?

You’ll need to get at least one major improvement (such as solar panels or a heat pump) via our suppliers.

However, you can get others from alternative suppliers if you wish. In this case we do ask that you let us know what other improvements you’re making and when you’re getting them. This is so we can calibrate the measuring of impact from the works.

How long is the project?

The project ends in March 2025 and we are looking to do final installs of the first one hundred properties by the end of 2024.
