Our Zero Carbon Heating Trial

The next steps

We’re hitting pause on new applications for now. But if you’ve already told us you’d like to take part, just sit tight. We’ll be in touch soon to let you know what happens next.

Then, it’s the really exciting part: testing out our pioneering zero-carbon heating systems. We can’t wait to share what we learn.

Join the UK’s low-carbon heating revolution

Exciting news! We’ve been chosen by the government to run the UK’s largest zero-carbon heating trial. Now, we’re looking for households in the South East to take part.

If you join, you’ll have your fossil fuel heating system replaced with a brand new one full of low-carbon tech – powered by electricity.

Lighten your carbon footprint with up to £15,000 of tech

Installed in your home at no extra cost.

By taking part, you’ll not only enjoy a greener home. You’ll help prove that low-carbon heating is cleaner, more cost-effective – and ready for everyone! Lots to feel good about.

You’ll get:

A low-carbon heating system

To replace your current one

Energy efficiency upgrades

Worth up to £5,000 for your home (like loft and wall insulation)

A more planet-friendly home

Your new super-efficient heat pump will cut the carbon caused by your home energy use by 36%¹

Full manufacturer’s warranty

Plus 3 years repair and maintenance cover

The coolest way to heat your home

Every home is different. We’ll survey yours to figure out which mix of low carbon tech suits yours best. Whatever we end up installing is yours to keep – at no extra cost – once the trial ends.

Here’s an overview of the clever kit we’re using.

Heat Pump

Powered by electricity, they work a bit like a fridge in reverse. They use heat from the outside air or the ground to heat water used in your central heating system and/or hot water.

They’re super-efficient, too. For each unit of energy used to power them, they create 3 units of heat. And because they work in temperatures as low as -20°C, they can handle even the nippiest UK winter!

Our trial makes use of several different heat pumps:

  • Mitsubishi Electric Ecodan Air Source Heat Pumps
  • Daikin Air Source Heat Pumps
  • Vaillant Air Source Heat Pumps
  • Kensa Ground Source Heat Pumps

We’ll choose the one that works best with your home.

Hot water storage

To make sure you’ve got hot water when you need it, we’re using a mix of highly-efficient hot water cylinders and heat batteries – an amazing bit of tech.

Heat batteries use ‘phase change materials’ to quickly turn stored energy into heat for hot water or heating. And they’re incredibly efficient at storing lots of energy in a small space, too.

Our trial makes use of:

  • Sunamp thermal batteries
  • Hot water cylinders

Additional home upgrades

We know the comfort of your home is important. Our survey will check if you need upgrades like loft insulation or draught-proofing, once we've got your thumbs up, we'll make them.

We can make up to £5,000-worth of energy-efficiency upgrades to your home, so your heat pump can work at its best.

How the trial works

Step 1

If you're accepted for a place, we'll do a remote home energy assessment to measure the energy performance of your home – and book a date for a home survey

Step 2

Once the home survey is complete, we'll get in touch to discuss the mix of heating tech that will suit your home

Step 3

Once you've given us the thumbs up, we'll book in a date to remove your current heating system and replace it with a new one

Step 4

We'll check the installation has been finished to the highest standard, sign everything off and leave you to enjoy your low carbon home

We’ll be on hand if you have any questions or need help, plus we’ll be in touch throughout the trial to get your thoughts on how everything is working.

This trial is a BETA trial - as the trial develops certain elements and processes are subject to change. To view full trial terms and conditions click here.

1 Replacing a gas boiler with a heat pump can reduce home energy carbon emissions by approximately 36%. This is based on the average UK household’s energy use in a year. Emissions factors were sourced from BEIS (the Department for Business, Energy and Industrial Strategy). The coefficient of performance for the heat pump used in this trial was 2.8.
