The Great British Insulation Scheme: How to Get Free Home Insulation

The Great British Insulation Scheme (GBIS) is a key step towards making UK homes more energy-efficient and eco-friendly through the provision of free home insulation. 


This scheme helps people insulate their homes, by adding insulation to walls, lofts, and floors. It's especially designed for homes that need it the most, based on their Energy Performance Certificate (EPC) rating and Council Tax bands. 


By improving insulation, the GBIS helps cut down on energy bills and keeps homes warmer. It's not just good for saving money, but it's also great for the environment. This is because better insulation means using less energy, which is good for our planet.


This article will provide an in-depth look at the Great British Insulation Scheme (GBIS), covering who can benefit from it, how to apply, and the different types of insulation it supports. 


We'll explore the financial aspects of the scheme, including potential costs and savings, and discuss its impact on both individual households and the environment.

The article will also address the broader implications of GBIS for the UK's energy policy and sustainability goals, and outline any challenges or limitations of the scheme. Whether you're a homeowner, landlord, or tenant, this article will give you a comprehensive understanding of how the GBIS could affect you.


What Difference Could Free Home Insulation Make To You? 


Imagine your home fully insulated against the cold. Now imagine being able to get free home insulation. This is made possible with government grants, such as GBIS and the Energy Company Obligation scheme. 


Before we look at how you could qualify for free home insulation, let’s take a look at why this home improvement is so important and the difference it could make. 


Energy Efficiency and Comfort

Home insulation is vital for maintaining an energy-efficient home. It serves as a barrier, keeping the home warm during winter and cool in summer. This not only ensures a comfortable living environment year-round but also reduces the strain on heating and cooling systems.


Cost Savings

One of the most immediate benefits of loft insulation and wall insulation is the reduction in energy bills. By minimising the need for constant heating and cooling, insulation can lead to substantial long-term savings, making it a cost-effective investment for homeowners.


Environmental Impact

Insulation contributes significantly to environmental conservation. It reduces the overall energy consumption of a home, which in turn lowers greenhouse gas emissions. This is crucial in the fight against climate change, as residential energy use is a major contributor to the global carbon footprint.


Overall Home Health

Proper insulation also plays a key role in the health of your home. It can prevent problems like moisture build-up, which can lead to mould and mildew. This not only protects the structure of the home but also ensures better air quality, contributing to a healthier living space.


In summary, the importance of home insulation extends beyond just energy savings; it encompasses environmental sustainability, improved home comfort, and the overall health of the living environment.


What is the Great British Insulation Scheme? 


The Great British Insulation Scheme (GBIS) was introduced in response to rapidly rising energy bills and a growing need for improved energy efficiency in UK homes. Historically, a significant portion of British homes have been inadequately insulated, leading to high energy consumption, increased carbon emissions, and costly heating bills for residents. 


The UK government, recognising the dual challenges of climate change and energy poverty, launched GBIS as a solution to these issues.


The primary objective of the GBIS is to provide accessible insulation solutions to households, particularly those with lower energy performance certificates (EPCs) and in specified Council Tax bands. 


By targeting homes that would benefit the most from improved insulation, the scheme aims to reduce the overall energy consumption across the country, thereby lowering household energy bills and decreasing carbon emissions.


What Else Does GBIS Focus On?

The expected outcomes of the scheme include significant improvements in home energy efficiency, reductions in national energy demand, and progress towards the UK’s environmental goals. 


GBIS will also play a crucial role in promoting public awareness about the importance of energy efficiency and sustainability in the residential sector. 


Furthermore, the scheme is anticipated to contribute to the broader economic and social objectives, such as creating job opportunities in the green sector and reducing energy poverty among vulnerable populations.

In summary, the GBIS was launched as a strategic initiative to address the energy inefficiencies in UK homes, with a focus on enhancing the quality of life for residents, supporting environmental sustainability, and contributing to the country's long-term energy and climate objectives.


What Types of Free Insulation Are Available Under GBIS?


Under the Great British Insulation Scheme (GBIS), several types of insulation are available, each

addressing different needs within a property. Let's delve into each type:


Cavity Wall Insulation

Cavity wall insulation is inserted into the space between the inner and outer layers (leafs) of external walls in a house. It's especially effective in homes with suitable brick and block walls. This insulation type reduces heat loss through walls, thus enhancing energy efficiency and comfort.


Loft Insulation

Loft insulation is a popular choice due to its cost-effectiveness and minimal installation disruption. It's laid in the loft space or attic to reduce heat escaping through the roof. This type of insulation is particularly beneficial for homes that lose a lot of heat through the roof.


Solid Wall Insulation

Solid wall insulation can be external or internal and is used in properties that don't have cavity walls. It involves adding a layer of insulation material to the wall, either on the inside or the outside. While it's the most complex and potentially costly option, it offers significant energy savings.


Pitched and Flat Roof Insulation

Roof insulation, for both pitched and flat roofs, helps reduce heat loss. For pitched roofs, insulation is usually placed between the rafters, while for flat roofs, it's installed either above or below the roof deck.


Underfloor Insulation

This insulation is installed beneath the floorboards or concrete floor, helping to prevent heat loss through the floor. It's particularly beneficial in older properties where there may be significant gaps or little existing insulation.


Solid Floor Insulation

Solid floor insulation is applied over solid concrete floors. This type of insulation can be more complex to install, as it often requires raising the level of the floor to accommodate the insulation material.


Room-in-Roof Insulation

This is suitable for properties with rooms in the roof, such as converted attics or lofts. It involves insulating the sloping sides of the room within the roof space.


In addition to these primary measures, certain heating controls, like room thermostats, may also be allowed as secondary measures, particularly in low-income group properties. 


However, it's important to note that higher-cost measures like solid wall insulation may require a financial contribution from the household. A home survey will determine which measures are the most suitable. 


What Type of Insulation is Best For My Home?


Determining the best type of insulation for your home depends on various factors, and a free survey conducted by a professional surveyor is the ideal way to ascertain this. During the survey, the surveyor will consider:


Type of Building and Construction: The age, design, and construction materials of your home significantly influence the suitable insulation type.


Existing Insulation: The surveyor will assess any current insulation to determine if upgrades or additional insulation are needed.


Local Climate: The typical weather patterns in your area will influence the insulation choice.


Energy Performance: The surveyor checks your home's energy efficiency, focusing on areas with significant heat loss.


Health and Safety Concerns: They will also look for any potential hazards like dampness or poor ventilation that need addressing.

Ultimately, the survey will provide a tailored recommendation, ensuring the chosen insulation method optimises energy efficiency, comfort, and safety for your specific home.


The Many Benefits of Free Insulation for UK Homeowners

The GBIS offers significant benefits to households by providing free or subsidized insulation. These benefits include:


Reduced Energy Bills: Insulation is a key factor in decreasing energy consumption, leading to lower heating and cooling costs. This reduction in energy bills is especially beneficial for low-income households.
