Contract signing
Once any necessary finance arrangements are in place, contracts are signed in your account and you'll have a full record of what's happened and when. You still have a cooling off period of 2 weeks, but you can choose to waive this - entirely it's up to you.

Pay your deposit
After the cooling off period the installer makes an application to the power network, and applications for any applicable grants are made, at which point your deposit becomes due. You pay the deposit to Thermly, then we arrange payment to your chosen installer to purchase the equipment and materials required for your installation.

Completion & Aftercare
Through the Boiler Upgrade Scheme, you can apply for a grant to cover part of the cost of replacing fossil fuel heating systems with a heat pump.
This scheme is open to people in England and Wales who own the property they’re applying for (including if it’s a business, a second home, or a property you rent out to tenants).
Check the requirements below to make sure that you are eligible to receive the £7,500 grant. Bear in mind that from next year, air to air heat pumps will also be able to secure a grant, but at the much lower rate of £2,500.
At Thermly we believe it should be easier for people to make decisions that benefit their home, their community, and the planet.
We’re passionate about collaborative projects and initiatives that support this ambition, so we built the Thermly platform to do just that.
