Retrofitting your home – what’s involved and what do you need to consider?

03 August, 2023Gordon Reid

Retrofitting your home is a transformative process that involves making targeted upgrades and improvements to enhance energy efficiency, comfort, and sustainability. As the world becomes increasingly conscious of environmental impact and rising energy costs, retrofitting has gained popularity as a cost-effective and responsible way to improve living standards while reducing our carbon footprint.

Over the last few months, I have set out to understand the options available, with a view to creating an effective and affordable plan to improve the efficiency and sustainability of my own home.


Energy audit and assessment

A great first step in any plan is to evaluate your current position. In relation to retrofitting your home, having an energy audit and assessment is advisable. A consultant will thoroughly examine your home’s energy consumption patterns, insulation levels, air leaks, and the efficiency of your heating and ventilation systems. The results of this provide valuable insights into the areas which need attention, helping you prioritise changes that will have the maximum impact.

Insulation upgrades

Improving your home’s insulation is a fundamental aspect of retrofitting. Adequate insulation prevents heat loss during winters and keeps your home cooler in summers. Common insulation areas include your attic, walls, floors and windows. Materials like fiberglass, foam and cellulose are commonly used to upgrade insulation, creating a more comfortable environment and lower energy bills.

Doors and windows

Replacing your old windows and doors with modern energy-efficient alternatives can significantly improve your home’s thermal performance. Double or triple-glazed windows can minimise heat transfer, while energy-efficient doors with proper seals prevent air leakage. In addition to enhancing the insultation of the home, these changes can also reduce noise and improve the look of your home.

Lighting and appliances

Switching to energy-efficient lighting and appliances is an essential part of retrofitting. For example, LED lighting consumes significantly less energy and lasts much longer. Similarly, upgrading old appliances, such as fridges, washing machines, and dishwashers, with energy star rated models ensures reduced energy consumption and lower utility bills over time.

Heating and ventilation

Your heating and ventilation system is a significant contributor to the home’s energy consumption. Retrofitting this could be as simple as installing a programmable thermostat or upgrading to a more efficient boiler. Additionally, people are exploring renewable heating and colling options, such as geothermal heat pumps or solar water heaters, which can further enhance your home’s energy efficiency.

Renewable energy integration

Integrating renewable energy sources can take retrofitting to the next level. Solar panels are a popular option for generating clean electricity. By harnessing the power of the sun, you can reduce your dependency on the grid and potentially sell excess energy back to your supplier. Like other upgrades, the initial investment can be substantial, but long-term savings and environmental benefits make it worth considering.

Water efficiency

There are several changes which can significantly reduce your water consumption and utility bills. Low flow taps, showers, and toilets, as well as high-efficiency appliances, are simple ways to conserve water. Additionally, rainwater collection systems can be used to collect and reuse rainwater for irrigation purposes, further reducing your environmental impact.

Retrofitting your home – contributing to a greener future

Retrofitting your home involves taking a holistic approach, combining energy-efficient upgrades, renewable energy integration, and water conservation measures. By first identifying the areas which require attention, it is possible to prioritise your retrofitting efforts according to your budget and goals. A professional assessment will typically cost approximately £200; however, given that a total retrofit of a typical UK property can cost upwards of £50,000, this is a small price to pay to ensure you use your budget wisely.

In addition to contributing to a sustainable future by reducing your carbon footprint and overall environmental impact, retrofitting enhances the comfort and value of your home.

Like many people, I simply can’t afford to undertake all the suggested upgrades. But, at least I know what I can do now, what my next steps will be, and I am reassured that I am doing my bit to create a more efficient, comfortable, and eco-friendly living space for future generations.
