What does Retrofit mean and where should you start?

Domestic retrofit is like giving your home an energy-efficient upgrade. In the UK, houses contribute 25-30% of greenhouse gas emissions, mainly from using gas boilers and electricity from fossil fuel sources.

Retrofitting is a game-changer for your home; it reduces energy bills by cutting down on fuel usage. By boosting your home's energy efficiency, typically through new insulation, glazing, and better airtightness (draft proofing), it lessens the heat lost through your home's fabric. This means you won't need to use your heating as much, saving both energy and money.

But it's not all about the bills. A good retrofit also improves your comfort and health. Poorly insulated and ventilated homes often suffer from condensation and moisture build-up, which can lead to respiratory problems due to damp and mould. A good retrofit fixes these issues, making your home a more comfortable and healthier space.

Retrofit is also an investment in your home's value. Without proper maintenance, your home’s value can dwindle over time as problems grow. Retrofitting helps avoid this decline. It can help to future-proof your home against climate change, ensuring it stays protected for years to come.

So, how does it work? Every home has different energy needs. Some use more for heating, some more hot water, and then there's all the energy used by appliances, electronics, and lighting. So how do you know what retrofit measures are best for your home?

First, you will need a home assessment. You need to know which areas of your home are causing problems, and where improvements can be made.

Next, consider the options. A good whole-house retrofit addresses your home's fabric, services, and renewable energy systems simultaneously. It's about considering all these elements together with a holistic approach because they affect each other. For instance, improving insulation can reduce the need for heating, and impact which heating strategy may be best for your home.

Then, come up with a retrofit plan. A 10-20 year ‘medium term’ plan can make your home more efficient without causing major disruption - think of it as a way to upgrade your home step by step. It's about finding the best ways to save energy and money without turning your life upside down. The key to retrofitting isn't just the 'how' but also the 'when'. Pivotal moments in your life can provide opportunities to upgrade your home. It could be extending your home, changes due to people moving out or arriving, essential service upgrades, or even just when it’s time to decorate.

And finally, the retrofit design. Even a good plan will fail if you don’t know how to implement it. A good retrofit design will specify exactly what needs to happen, where it needs to be done, and how. After that, you’re ready to start!

All in all, retrofitting isn't just about your home. It's about doing your part for the environment while also saving on bills, improving your home's value, and creating a healthier, comfier living space that stands the test of time. So, think of it as making your home a bit smarter, cozier, and kinder to the planet. It's a win-win for you and the world around you.
