Retrofitting your home can help to lower your energy bills and make your home warmer — here’s what you need to know.Retrofitting helps to improve a property’s energy efficiency through the addition of new technology or features, and it can help to save you money on your long-term energy bills.



There are different ways to retrofit a house, varying from single-room improvements to whole house retrofits, but each process is ultimately designed to increase your energy efficiency. This focus on efficiency is why retrofitting differs from renovating a house or making home improvements designed to make a home more aesthetic.

Several industry groups believe retrofitting the UK’s housing stock is essential, especially if the UK is to reach net zero by 2050, which is why many industry groups are campaigning for a National Retrofit Strategy to be introduced to help provide a roadmap.This guide will explain why there is a growing push for homeowners to retrofit their homes, how this can be achieved, and why making energy-efficient improvements can benefit your home.

Retrofitting your home in one go can be cheaper for some homeowners.

There’s no official definition of retrofitting, but as Chayley Collis and Bill Butcher from Green Building Store explain: “It is more than just renovating a building and involves more substantial changes to the original building into something much more energy efficient.”Retrofitting typically involves a significant improvement in the thermal performance and comfort of your home, and by improving the fabric of the building.

Paul Testa, founder of Paul Testa Architecture and contributor to Homebuilding & Renovating, adds: “Retrofitting is multi-faceted and can include insulating roofs, walls and floors; replacement windows; improved ventilation design; airtightness works and more efficient heating and hot water systems. Renewables are also often installed during retrofit works.”
