Hi I'm Bertie, I am a UX designer that has a passion for emerging technologies. I strive to design solutions that are innovative, ground-breaking and user centred. Join me on my journey.

Toastie – where sustainable just got affordable.

The Problem:

Residential heating is responsible for 16% of the UK’s CO₂ emissions. To achieve Net Zero by 2050, domestic properties will need to make the switch to a decarbonised heating source such as a heat pump. In order to install a heat pump in your home, you will need to be “heat pump ready”, which can be a long, complex and expensive process. The UK housing stock has a notoriously low energy efficiency – which means a-lot of our homes will require future proofing. When I say a-lot, I mean 29 million domestic properties. So the big question is – Is Britain even fit for heat pumps?

What we do:

Switching to a heat pump is the single most effective thing a household can do to drive down carbon emissions. But right now, uptake is far too slow due to the complexity of home retrofit. But Toastie is changing that. We will accelerate adoption to the rate where it’ll really make a difference to our nations footprint. How? We build personalised retrofit timelines that will make your home both energy efficient and heat pump ready in a sustainable, affordable and very doable way. Embrace the clean energy revolution and join Toastie now…


How we do it:

Following the Toastie home energy assessment, our team of experienced green energy experts will craft a personalised timeline tailored to your property, needs and budget. Rest assured, if a particular date doesn’t align with your schedule, it can be seamlessly adjusted in a matter of seconds on the control panel.

The retrofit timeline is fully interactive, enabling users to click on individual jobs, adjust their dates, and see how each job could enhance their energy savings and increase their home value. Our team of in-house financial advisors are always available to assist users who need help managing their timeline budget.

The Toastie app uses cutting-edge technologies to elevate user experiences. Its intelligent AR scanner offers users visual cue overlays, enhancing their retrofit jobs with unprecedented clarity, precision and innovation.

Strategic partnership with Aira:

We get it, Finding “heat pump ready” customers can be hard. So that’s why we’ve teamed up with Scandinavian heat pump manufacturer – Aira.

We aim to provide Aira with a steady stream of heat pump ready customers, while they provide us with those who are the opposite. It’s a synergistic collaboration designed to maximise outcomes for both parties involved.
A true win win scenario…
