How can we improve the energy efficiency of UK homes?

We’ve been exploring the 4 key steps to meeting net zero targets for the UK housing sector:

Improving the energy efficiency of our devices would deliver carbon emission savings of 3.1 million tonnes per year

How can energy efficient devices bring us closer to Net Zero for UK housing?

Energy efficient devices can play a crucial role on the path to meet the government’s commitment to Net Zero if widely adopted.

Energy efficient devices, such as appliances and light bulbs, reduce the overall demand for electricity throughout the country. This alleviates pressure on the grid during periods of peak usage, contributing to the early decommissioning of fossil fuel and coal power plants. Together, these benefits can reduce emissions while saving people money on their electricity bills.

Implementing simple home improvements, such as low energy lighting, costs between £15 and £400 per modification, and could collectively reduce the national fuel bill by up to £900 million and save the planet 3.1  million tonnes of emissions every single year. Despite these properties needing to improve the most, close to 11 million properties are yet to switch some or all of their lighting to energy-efficient light bulbs. 

The South West leads the way with 57% of homes already using energy efficient light bulbs and 5% installing solar panels, the North West, however, lags behind with only 51% of homes using energy-efficient light bulbs. This shows that mass adoption is possible but is potentially being hindered by socioeconomic factors.

An example of energy efficient device upgrades: LED light bulbs

Lighting accounts for around 15% of average household electricity consumption in the UK. 

While upgrading light bulbs has less of an impact on the overall emissions of a house compared to other upgrades, such as solar panels, it’s a low cost, low effort measure homeowners can take to improve their EPC rating. Collectively, widespread adoption of energy-efficient lighting can have a significant impact on the reduction of emissions from the housing sector.

The following table illustrates the energy and cost savings if all or most of the lightbulbs in a household are upgraded:

Regular light bulbs Energy efficient light bulbs: Compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs)
Life length 750-1,000 hours 6,000-15,000 hours
Electricity conversionAround 5% of the electricity they use converts into visible lightAround 20% of the electricity they use converts into visible light
Energy bill savings NA £30 per year (per house)
Average CO2 emissions savings (annual)NA0.12 tonnes (per house)

The UK has been making strides in this department to encourage the country-wide transition to energy-efficient light bulbs.

They began phasing out higher-energy halogen light bulbs in 2018 (under EU wide rules) and banned sales of such light bulbs in September 2021. Additionally, there is legislation being brought forward in January 2022 that will remove fluorescent lights from shelves from September 2023. However, more could be done to encourage people to upgrade their devices. 

Are energy efficient devices an underused opportunity for property decarbonisation?

Kamma’s first step focuses on efficient devices and their role in helping us achieve Property Zero, and while our data primarily covers light bulbs, it does so because they are the most appropriate and illustrative example.

Because this first step is so simple and straightforward, it is often overlooked. This is clear from the number of business-focused regulations in the legislative pipeline.

Alternatively, the UK government may just see a greater role for industry in the fight against climate change – citizens taking sensible steps is not mentioned in government documentation.

Considering the legislative evidence and the impact of non-efficient devices, we see this as an underutilised opportunity. 

The Climate Change Committee talks specifically about the need for behavioural change in order to deliver Net Zero targets, and there are attempts being made to address this. For example, phasing out light bulbs and adding EPC ratings to light bulb packaging. However, more needs to be done to ensure energy-efficient devices have a significant impact. The benefits of educating citizens and attempting to nudge behaviours in the right direction is currently being overlooked.

How to ensure energy efficient devices contribute to Net Zero housing in the UK

Using energy efficient devices could collectively reduce emissions by 3.1 million tonnes annually. That is, of course, if they are adopted on a wide enough scale. So, how do we get there?

Education and awareness campaigns are key.

We know that the government is currently making concerted efforts to try and change behaviours and empower citizens to embrace energy efficient devices.

But, to achieve this first step and ultimately Property Zero by 2050, more of an emphasis needs to be placed on making energy efficient alternatives cheaper and widely available.

An excellent example of a proactive government campaign comes from The Carbon Trust. A partnership set up to offer grants for LED Lighting of up to £5,000 for small and medium-sized UK businesses that could benefit from financial support when buying and installing energy-efficient equipment.

An attempt needs to be made to change habits as well as devices. To invoke a cooperative spirit and make people realise the importance of taking a small step can have a significant collective impact.

Energy efficient devices are step 1 in the path towards Net Zero UK housing

One of the reasons behind the creation of Kamma’s 4-step pathway to Property Zero was to assess government policy and the efficacy of their supposed strategy. On the path to Net Zero, energy-efficient devices can play a pivotal role, but currently, the government is not placing enough importance on mobilising homeowners to upgrade devices.

With our interactive Property Zero website, we also hoped to create an easily consumed narrative to engage and mobilise the public to drive their homes toward Net Zero. Collectively, we can all be a part of this journey, and by raising the level of awareness and debate, we ensure a swifter and more efficient path to carbon neutrality for UK homes.
