How to retrofit

There are lots of energy efficient technologies available to help you retrofit your home. What’s important to know though is the correct way to use these measures, as well as the correct order to install them to ensure your home is as energy efficient as possible.

A fabric first approach

For your home to be retrofitted to a high standard that prevents future problems, such as mould and excess energy costs, we recommend following a flow of priorities when it comes to upgrading your home’s energy efficiency. 

We call this the ‘fabric first’ approach, which means improving your home’s structural elements – walls, floors, roof, windows, and doors – before adding any energy efficient measures so that it’s properly insulated and can retain heat effectively.

Step 1: Insulation

The first thing to do before installing a low carbon heating system or generating your own renewable energy is to ensure your property has proper insulation. To be able to make the home warmer and be able to hold a warmer temperature for longer, it needs to be properly insulated

Step 2: Ventilation

By adding a warm layer of insulation to your home, moisture will build in the property. It is now essential you look to install effective ventilation to allow your home to breath.

Step 3: Electrification

Once your home is properly insulated and has appropriate ventilation, the next step is to electrify the heating system with the likes of an air source heat pump. This is known as decarbonising the heating.

Step 4: Generation

Now your home is warm, ventilated and running an efficient heating system, the last step is looking at generating your own renewable energy with the likes of solar panels.

Tackle the climate emergency

13% of Scotland’s greenhouse gas emissions come from the home. If your home is better insulated, it’ll leak less carbon, which will help tackle the climate emergency.
