how it works

Next, one of our Retrofit Coordinators will come and assess your house to find out everything we need to know about your property. Your Retrofit Coordinator will then use this information to develop a bespoke survey, plan or specification for your home depending on your chosen service.

Once you’ve received your survey or house plan and chosen your home improvements, our Retrofit Coordinator will prepare a detailed specification to help you get accurate quotes for the work.

If you're a new customer and don’t want a plan, don’t worry — we can still help you gather quotes. Please note: if you haven’t had a survey or house plan through us, there is a charge of £80 for an assessment visit, plus the cost of any measures you choose.

Each specification is a standalone document, and we charge a fee per specification. Further details and costs can be found here.

This stage is key to our whole house retrofit approach, especially for complex projects involving multiple measures. A detailed understanding of the building ensures contractors can avoid issues like thermal bridging, poor ventilation, or damp.

We support you through the quoting process by requesting and presenting quotes from trusted contractors on your behalf. Once quotes are received, we carefully review them to ensure they’re suitable and fairly priced, giving you confidence in both the scope and value of the work. We then share the quotes with you and help you compare your options, so you can make an informed decision that suits your home and your budget. You can learn more about this stage here.

If you decide to go ahead with a contractor we’ve sourced for you, we’ll support you throughout the entire process. This includes site visits, reviewing and clarifying quotes, providing technical oversight, signing off the completed work, and helping resolve any issues with the contractor.

To cover these services, we charge a 5% + VAT service fee based on the total project cost.

Please note, any required building control approvals or planning permissions are your responsibility, as per UK law. There’s no obligation to go ahead with the work after receiving your specification. You can learn more about this stage here.

Our Retrofit Coordinator will review and sign off the completed work, and will be available to answer any questions you may have. Then, it’s time to enjoy your upgraded home — knowing you’re helping the planet while also cutting down on your energy bills.
