Why have an energy efficiency survey?

A home energy survey is a great first step to making your home more sustainable, helping you to save energy and money in the long term. Many homes leak heat through windows and doors and uninsulated walls. Knowing the right action to take to save bills and cut carbon is difficult.

Home surveys can pinpoint your home’s specific problems, helping you know where to start with making improvements. You’ll learn the steps you need to take to fix issues, appropriate energy improvement measures like insulation and draughtproofing, and what renewable energy technologies – like heat pumps and solar panels – could work for your home and your circumstances.

What is retrofit?

You may have heard the phrase ‘retrofit’. Energy improvements measures like insulation and draughtproofing are sometimes referred to as retrofit measures. Retrofit simply means fitting new measures in buildings after they’ve been built.

Home energy efficiency surveys available

Several survey options are available depending on your budget and the level of detail you want. Below are the surveys we recommend from the Centre for Sustainable Energy (CSE) and Chapter 2 Architects. But you can use your discount on any of Chapter 2 Architects’ surveys, which you can view on their website.

During the winter months the survey also includes thermographic imaging to identify heat loss. You’ll receive a bespoke report with helpful diagrams and images based on the findings.

The Retrofit Opportunities Plan runs through each measure in turn ranging from quick DIY actions to adding insulation, upgrading your heating system or adding renewable technologies.

Thermographic Imaging Report

Cost: £50 with the voucher discount
It takes: 1 hour
What you get: A thermographic imaging survey and report from qualified Retrofit Coordinator and Architect, Alex Bell.
How to book: Email and quote NS250.

This report uses thermographic imaging to identify the areas of heat loss in your home. These are typically through poorly insulated elements of the building’s fabric (walls, floors, roofs) and at the junctions with doors and window.

Chapter 2 Architects will conduct a thermal imaging survey of your home. This will go room by room internally and also analyse the building from the outside. It is a very enlightening and interactive process which most homeowners enjoy participating in. You’ll receive a report documenting these areas offering both diagnosis of the issues along with suggestions for improvements through insulation or draughtproofing measures.
