How to reduce your home’s carbon emissions

The UK is currently working towards a target of net-zero emissions by 2050 and around 22% of the country’s carbon emissions currently come from our homes, including heating, lighting and appliances, so this is a great place to start. We all have a part to play and the good news is that there are many things we can do to lower our household emissions, so here are a few simple tips which can add up to a big difference.

1. Use heating controls

For most of us, the first step in cutting carbon emissions is to take control of our heating. We can reduce our carbon emissions and energy usage by making sure we’re not using more heating than we need. Smart heating controls are available for all types of heating systems, including electric storage heaters. Some systems include automation features, which can help by working out exactly when to turn the heating on and off. In fact, by installing a smart thermostat, you could save up to £75 and 330kg of carbon a year.

2. Invest in solar panels

Installing solar panels is a good way to lower your carbon emissions. Solar energy is a natural, renewable source because it can be replenished, unlike finite fossil fuels. Solar energy produces little or no emissions when it’s converted to electricity. Fortunately, for those of us living in the UK (where the sun doesn’t always shine) solar cells still work on cloudy days, although less electricity is generated. The Energy Saving Trust estimates the average UK home with a solar PV system installed could reduce carbon emissions by 1.3 to 1.6 tonnes per year depending on location.

3. Switch to energy-efficient appliances

Moving to energy efficient appliances can be an excellent way to save money on your bills, as well as reducing your home’s carbon emissions. All electrical appliances such as dishwashers, fridges and washing machines have to carry a Europe-wide energy label which indicates how efficient (or inefficient) they are. After a revamp of the grading system in 2021, new appliances are officially graded on a scale from G (least efficient) up to A (most efficient). Looking at the energy-efficiency rating is vital when shopping for your household goods, so keep an eye out for the coloured sticker on the appliance showing its rating.

4. Seal and insulate your home

Adding insulation and air sealing can make your house significantly more efficient: it’ll stay warmer in winter and cooler in summer while using far less fuel. The majority of energy used in homes, 63%, is for space heating. Insulation reduces the amount of heat lost through walls, roofs and floors, meaning that less energy is required to heat a building.  Home insulation is the single most effective method of reducing carbon emissions; a detached home fitted with solid wall insulation could save up to 2 tonnes of carbon per year, as well as saving you money on domestic energy bills.

5. LED low voltage light bulbs

Changing your light bulbs to low-voltage LED bulbs is one of the easiest and quickest ways to save energy. You can get most kinds of LED bulbs in the supermarket, so you can pick them up alongside your normal weekly shop. LED bulbs have advanced over the years and are now as bright as standard light bulbs, so the only change you can expect is a reduction in your electricity bills. LED bulbs use around 90% less energy than halogen bulbs and last 50 times longer. Making this change could save you about £35 a year. For more cheap and easy tips check out our blog here.

Selling more houses with videography

Videography is still a relatively new addition to selling houses, but now that people have realised the power of video it is becoming increasingly popular. Video can show the life and soul of a property better than static images, as it can highlight the flow of the accommodation, how one room opens to the next, and gives a better idea of scale when combined with photos and floor plans. Estate agent videography is the next best thing in selling houses and we’re excited to see how the industry is embracing new technologies.
