With inflation potentially hitting new highs this Autumn, and a significant increase in the average home energy bill, we’re all focused on squeezing every last penny out of our pay packets and scrutinising each element of our essential spending, from transport, to electric, to food and so on.
The measures proposed by the country’s new prime minister and her cabinet will of course go some way to ease our pain, but are unlikely to stretch very far when the price of everything else is also sky-rocketing.
Of course, the consequences of the rise in the energy price cap and the cost of living in general will be devastating for many, with people forced to choose between heating or eating. It may all seem too much to think about, but making a few changes now could really pay dividends – both in the short term to get through the winter, and in the longer term, for you and the planet.
Benefits for both pocket and planet
A study by home improvement site Rated People revealed 57 per cent of people want to be more eco friendly at home.
This is good news for the planet, with the Energy Saving Trust revealing 21 per cent of the country’s carbon emissions come from the UK’s residential homes. Not surprising when 85 per cent of British homes are run on gas central heating and the average household generated 2690kg of carbon dioxide from home and hot water heating in 2020.
Over the next 30 years, we need to reduce that number to just 140kg per household – this is in order to meet the Government’s net zero target and reduce household carbon emissions by 95 per cent by 2050.
Further data from Count us In, a global movement of people and organisations taking high impact steps to address climate change, reveals that individual lifestyles make up more than 65 per cent of total carbon pollution globally.
So, since household energy changes are likely to bring the biggest benefits for both our pockets and the planet, let’s begin by looking at some ideas to tighten up on energy at home and potential home energy-saving upgrades – both to get us through this winter and benefit the planet for years to come.
Home and water heating
Over half of our fuel bills go towards heating our homes and water. Some ways to make our home heating more efficient:
- Turn down the thermostat! A one degree reduction can save around 10 per cent on your annual heating bill.
- Turn down your boiler temperature and programme your thermostat to heat your home only when you need it. A smart thermostat can do this remotely for you and costs around £150 – £300 but can save around 14 per cent on energy bills according to Scottish Power.
- If you can afford it, consider a new boiler. A-rated condensing boilers are around 60 per cent more efficient, meaning
you could save between £350 and £800 against an older, D-rated boiler.
- Or, get an (air source) heat pump. Homes need to be well insulated for heat pumps to be effective, and costs beyond installing the pump itself could apply, such as new radiators, hot water storage tanks and additional insulation. However, you may well be considering some of these measures anyway. As part of the Boiler Upgrade Scheme, the Government is offering households in England and Wales grants of £5,000 against a purchase and installation cost of between £7,000- £13,000 to switch from a boiler to a heat pump. While less environmentally friendly, a modern A-rated gas boiler will cost less per year to run than a heat pump. Ground source heat pumps are also an option although less suitable for most UK households.
- Consider a targeted approach if it suits your household, and only heat one or two rooms at a time, using electric heating
- Solar water heating – installing solar panels costs around £5,000 and households with solar panels are set to save around £900 on next year’s energy bill compared to a household relying fully on an energy provider charging the price cap, according to The Eco Experts. Households with solar panels can also make money selling their unused energy back to the grid.
- Ecology Building Society offers C-Change discounts on mortgages of up to 1.50 per cent on its standard variable rate, rewarding customers for creating and energy-efficient home, allowing them to enjoy reduced energy bills while shrinking their carbon footprint.
Insulation, insulation, insulation
Reducing home heat loss is equally important. According to energy saving advice portal The Greenage, around 25 per cent of the heat in an average home will escape through the roof, 35 per cent through gaps, windows, doors and walls and roughly 10 per cent through the floor.
Some measures to consider:
- Simple steps such as fitting your hot water cylinder with an insulating jacket can save up to 115kg of carbon emissions as well as saving water heating costs. Insulate radiators.
- Wall insulation – insulating cavity walls costs around £1,200 for an average home and could save around half that amount on energy bills. However, solid wall insulation can be much more costly – around £12,000 for a three-bedroom semi.
- Roof insulation. It would cost around £500 for roof insulation in the average-sized home and again, savings can be up to half of that amount.
- Double glazing – making windows more energy efficient and replacing single-glazed windows with double glazing can be costly but savings can add up. Fitting a hot water cylinder with an insulating jacket can save 115kg carbon emissions as well as saving on heat costs.
Reduce energy usage
There are a number of small changes you can make at home to save on your energy bills, without a noticeable impact on comfort. For example:
- Washing your clothes on 30 degrees rather than 40 degrees uses around 40 per cent less energy. Opting for a quick wash rather than the full two hour cycle will also save power – and water.
- Tumble dryers use roughly 4.5 kWh of electricity per cycle From October. The average cost per kWh will be 34p. Try to avoid using dryers while the outside temperatures are still warm.
- Don’t waste hot water and the energy required to heat it – try using a simple washing up bowl instead. However, if you must use an energy-hungry dishwasher, make sure it’s on the Eco mode and is only used when full.
- Take your parents’/grandparents’ approach and make sure you turn the lights off when leaving a room – this can save around £40 per year.
- Make sure you have a smart meter, regularly submit readings, check each bill carefully and pay by Direct Debit to get the biggest discount possible.
Switch up to newer home appliances
While it may cost more in the short-term, it’s worth replacing outdated home appliances with new ones that are as energy efficient as possible. For example:
- An energy-efficient washing machine will save both energy and water. A new A-rated machine could cost around £800 to buy, but could shave between £50-£100 per year off your energy bill.
- Other appliances such as tumble dryers and fridges are also worth replacing to save up to £100 a year on energy bills.
- Lastly, switching to LED light bulbs only in the home can save around £30 per year on bills.
As many as one million homes in the UK are already generating renewable energy.
In addition to domestic renewable energy schemes, if you have money to invest that you don’t want going to a fossil fuel-funding bank or investment fund, it is possible to invest directly in renewable energy projects through organisations like the Good Egg company Thrive Renewables, which has been building and operating renewable energy systems in the UK for more than 30 years. Platforms such as Abundance Investment, Triodos Crowdfunding or Ethex are also worth checking out.
Other ways to go green at home
There are many other ways to go green at home. A brilliant resource for this is the Sustainable-ish website community. Blogger Jen Gale looks at:
- The benefits of electric vehicles (EVs) and low carbon travel more generally.
- How to create a more wildlife-friendly garden at home to better attract bees, butterflies and birds; plant more trees whether directly or via a central scheme.
- Reduce and recycle always. With a particular focus on reducing your food waste
- Eat more vegetables, consider a plant- based or flexitarian diet.
- Talk about the issues with anyone who’ll listen – and hold politicians accountable
- And last, but not least, make your money count. Explore and challenge the environmental record of your bank, savings provider, pension provider. Research from campaign group Make My Money Matter last year revealed that switching to a ‘green’ pension can reduce an individual’s carbon 21 times more than going vegetarian, giving up flying and switching to a green energy provider combined.
