How To Increase Your Home’s Energy Efficiency

In today’s world, homeowners are growing ever more aware of their property’s energy efficiency. Not only is the cost of living increasing, with fuel, electricity and heating prices skyrocketing, but we are also facing a global climate crisis. Greenhouse gases are having catastrophic effects on the environment and the rate at which the temperature of our planet is increasing could have dire consequences if we do not act fast.

Of course, the responsibility should not fall entirely on the shoulders of consumers and homeowners but, as it directly impacts the future of our planet and the cost of living now, it is only natural that we should seek out solutions.

One means of reducing the amount it costs to run your home, while also lowering the carbon footprint of a property, is to make it more energy-efficient. Although the term energy-efficient is used commonly, it can be somewhat vague and achieving it can seem daunting.

Here is Green Build CW’s guide to increasing your home’s energy efficiency.

Spray foam insulation


When embarking on the quest to increase the energy efficiency of your home, a good place to start is by considering how much energy is wasted. One of the main causes of wasted energy is inefficient insulation. If your insulation is not working effectively, you may be paying far more than needed to heat your home due to the compensation for heat loss.

There are a number of ways in which homeowners can improve the insulation of their property, however, the two most common methods are loft insulation and underfloor insulation.

Loft Insulation

A home’s loft is a common culprit of heat loss as the hot air from your house rises and escapes through poorly insulated roofing. Equally, cold air can easily make its way into a home through an uninsulated loft, forcing your heating system to work much harder than it needs to and costing far more than it should.

Employing an expert service to insulate your loft using spray foam technology is the best way to save your property from heat loss and cut costs on your energy bills. The results of this service are instantaneous, meaning your home will stay warmer in winter, and cooler during summer.

Underfloor Insulation

Similarly, underfloor insulation is a tried and tested method of improving your home’s energy retention, reducing drafts and boosting your energy saving by nearly 50%. Using the same technology as loft insulation, spray foam covers all gaps and possible air leaks, making your flooring far more efficient. What’s more, spray foam insulation has an equivalent lifespan to your building; it is a one-time installation.

New Boiler

Another sure way to cut down on costs and carbon emissions is to reassess your boiler’s efficiency. On average, boilers make up more than half of a home’s total energy bill, and if yours is working at a low-efficiency rating, it may be time to think about investing in a newer model.

Sure, there is an initial cost associated with the purchase of a new boiler, so it isn’t always possible, but the long-term savings and environmental benefits of a more efficient heating system are definitely worth it.

Finding out your boiler’s efficiency rating is usually a simple process, either locate the energy rating sticker on the body of the boiler itself or look up your model online.

Cut Down On Usage

We know this one sounds pretty obvious, but an effective way of cutting costs and lowering your carbon emissions is to reduce your household’s overall energy usage.

There are many easy ways to do this, such as shutting down electronics properly when not in use, turning off the lights when you leave a room and swapping out your old halogen lights for LED bulbs.

Additionally, simple changes such as taking showers instead of baths and washing your clothes at a lower temperature can make a noticeable difference. These actions may seem small, but if everyone makes an effort to reduce their usage, it can have a sizable impact on a larger scale.

Making a few alterations to your daily habits can have a positive impact on your carbon footprint and your energy bills.

Energy-Saving Appliances

Of course, it isn’t always as simple as using your appliances less; there are certain items that are essential to our everyday lives. However, a positive step is to consider the efficiency of these appliances and question whether you could find an energy-saving alternative.

There are many energy-efficient household appliances available at reasonable prices on the market today, ranging from electric ovens, dishwashers and eco-kettles. All of which can do wonders for your energy bill, using far less power and, subsequently, saving you money.

Double Glazing

Moreover, a prime example of inefficient heat retention can be found in the form of windows and single glazing. Many older properties struggle to stay warm during the colder months due to the outdated window panes used when they were first built; the pane of glass used in single glazing does very little for heat insulation compared to the newer technology available.

Using two panes of glass, engineered with airtight cavities and chambers throughout, double glazing massively reduces the occurrence of heat loss in your home. This, in turn, means that your heating system can maintain the temperature of your home far more effectively.

Renewable Energy Solutions

When it comes to reducing carbon emissions while simultaneously lowering the amount spent on electricity and heating in your home, there are few methods as effective as the implementation of renewable energy solutions such as solar panels and air source heat pumps. Whilst there are installation costs associated with both of these, the benefits far outweigh the costs.

Solar Panels

Put simply, solar panels use photovoltaic cells to absorb sunlight and convert it into an alternating current. This current is then pumped into your home to power your appliances.

Opting to have solar panels installed will provide your home with a constant source of electricity, enabling you to renewably power your property and even sell excess electricity back to the grid!

An added benefit of solar power is the option to install solar battery storage at the same time as your panels. High capacity storage systems allow homeowners to save up to 75% on their electricity bills by holding the renewably generated power until it is needed.

Air Source Heat Pumps

This form of renewable energy is installed in the form of a small unit on the exterior of your home. Air source heat pumps work by harnessing the heat present in the air outside of your property and transferring it to water. This water can then be used to fill radiators or underfloor heating.

One of the great things about air source heat pumps is that they can also heat water for taps, showers and baths!

Draft Proofing

The last, and arguably simplest, method of maximising your home’s efficiency is through draft proofing. Not only is this technique cheap, but it is also easy to enact. Draft proofing follows a similar school of thought to insulation; keep warm air in and cold air out.

Basic DIY draft proofing can be installed easily through the use of temporary draft excluders, however, utilising the knowledge and skills of a professional service is always recommended as it ensures effectiveness and longevity.
