Here’s how it works
1. Tell us where you live
Enter your postcode to get a basic snapshot using local data.
If your home is older (pre-1920s) or a bit unusual, it might not show up in the database – but don’t worry. Just give us a call and we’ll guide you.
2. Explore your options
Answer a few simple questions to see suggested improvements – including rough costs and potential energy savings.
3. Save or share your plan
You can save it for later, or send it to us for feedback. We’ll help you understand what to do next.
Prefer to speak to someone?
You don’t have to use the tool. If you’d rather talk it through – especially if your home is older or your situation is a bit different – we’re here to help.
Need a hand? Skip the tool and start with a conversation. Talk it through with Arantxa, our experienced Project Administrator & Retrofit Advisor, who is here to talk through your goals and how we can help.
Call 0330 223 2742 weekdays or send a message. Just friendly, practical advice.
