The best energy saving ideas for your home improvement project

Are you thinking about improving or modernizing your home?

There are many reasons people choose a home renovation project, from creating more space for a growing family to adding value to their property. Whatever your reason, it always pays to think about ways to improve the energy efficiency of your home with any renovation project. It could help lower your energy bills and improve your carbon footprint.

If you need inspiration then look no further! Here are Energy Saving Trust’s most popular renovation ideas that will improve the energy efficiency of your home.

Use energy efficient lighting

This is a simple start: make sure all lightbulbs in your home are energy-efficient LEDs. Replacing all light bulbs in your home with LED lights could reduce your carbon emissions by up to 40kg per year. And with lighting accounting for around 11% of the average UK household’s electricity consumption, switching to LEDs could also save you money on your bills.

Add drafts

Draft-tightness is one of the most effective ways to save energy, money and CO2. At an estimated cost of £240, professional draft sealing of windows, doors, floors and skirting boards will save you £95 a year and reduce your household’s carbon emissions by 220kg. If your budget doesn’t allow for a professional job, heavy lined curtains are an affordable quick fix that will help retain more warmth in your home.

Replace windows and doors

Making your doors and windows more energy efficient will reduce your energy bills and reduce your carbon footprint. Double glazing is the most popular option, although costs vary depending on the material and style. For example, PVC windows tend to be cheaper, while hardwood frames are the most expensive. Installing A-rated double glazing on windows in an all single glazed gas heated semi-detached house could save you £145 per year and reduce your CO2 emissions by 335kg per year.

Install heating control

By installing and using heating controls effectively, you can save money on your heating bills and reduce your carbon emissions. Set your thermostat to the lowest comfortable temperature, usually between 18°C ​​and 21°C. Turning your thermostat down a degree can typically save you around £105 a year, while installing and correctly using a programmable room thermostat and thermostatic radiator valves in the average semi-detached house can save you £130 a year.

Insulate your attic

Unless you live in a mid-floor apartment, heat escapes from your home through the roof. While most homes have at least attic insulation, this is often not enough. Padding from 120mm to at least 270mm of insulation helps – and saves you around £25 on your bills every year. Additionally, if your attic is easily accessible and doesn’t have moisture or condensation problems, it should be easy to insulate – and in many cases it’s possible to do it yourself.

Insulate your walls

Did you know that about a third of the heat lost in an uninsulated house escapes through the walls? Now it’s time to add some insulation. Most houses in the UK have cavity walls and the gap can be filled with insulation. We estimate that by insulating your cavity walls you could save around £285 a year on your energy bills and reduce your carbon footprint by 670kg.

Install solar panels

If you have the budget for some major renovation ideas, consider installing solar panels. This is the most widely used renewable energy source in the UK and once you’ve paid for the installation it will reduce your electricity bill – saving you around £475 a year on your bills (based on a typical installation with everyone at home). Day). They also reduce your carbon footprint by an impressive 750kg of CO2 emissions per year.

Switch to a heat pump

We’ve saved our favorite DIY for last: switching to a low-carbon heat pump. Heat pumps are an attractive longer-term and sustainable heating option. The most common domestic heat pump is an air source heat pump which will cost you around £7,000 to £13.00 to install. While the impact on your energy bills will depend on several factors including the fuel you are replacing, the efficiency of your heat pump and the design of your central heating system, your carbon footprint will see an impressive reduction. For example, if you replace your old gas boiler with an air source heat pump, you will reduce your CO2 emissions by up to 6,000 kg per year.
