UK loft insulation grant: A homeowner's guide.

Thinking of improving your home with loft insulation? You’re not alone. More and more people across the UK are looking into energy-saving upgrades, and thanks to government backed schemes, many households may be able to get help with the costs.
Here’s everything you need to know, with no fluff, no hard sell, and no jargon.
Understanding a loft insulation grant.
So, what is loft insulation and why does it matter? In simple terms, loft insulation helps stop heat escaping through your roof. Think of it like a woolly hat for your home, it keeps the warmth in and the cold out. Most of the heat we lose at home escapes upwards, and without proper insulation, your boiler, or air source heat pump could be working harder (and costing more) than it needs to.
Insulation works by trapping air in pockets between the fibres, slowing heat loss and keeping your home feeling cosier for longer, and loft insulation grants are part of wider efforts to improve the energy efficiency of UK homes. These grants are typically funded by the government and delivered through schemes like The Great British Insulation Scheme (GBIS), with support from energy suppliers, like us.
Grants are designed to help qualifying households cover the cost of installing insulation, and in many cases, it could be fully funded.
Benefits of a loft insulation grant for homeowners.
Energy savings.
A properly insulated loft can stop up to a quarter of your home’s heat escaping. That could mean less strain on your boiler and lower heating bills. Savings vary depending on your home, but the Energy Saving Trust estimates that topping up your loft insulation could save between £150 and £400 a year.*
Environmental impact.
While we're not here to preach, better insulation does mean your home uses less energy to stay warm, and that’s a practical step towards lowering your carbon footprint. No need to live in the dark or freeze under a blanket, just warmer homes using less fuel.
Home comfort.
This one's simple: good insulation makes your home easier to heat, and keeps it cooler in the summer too. Less draughty in winter, less stifling in July. Win-win.
Who's eligible for a loft insulation grant?
Loft insulation grants are usually aimed at households with lower incomes or people living in homes that are harder (and costlier) to heat. The criteria can vary depending on the scheme, but you might qualify if:
You own or privately rent your home.
Your property has an EPC rating of D or below.
You (or someone in your household) receive certain benefits.
Government criteria for eligibility.
The Great British Insulation Scheme (GBIS) is aimed at helping homes with an Energy Performance Certificate (EPC) rating of D or below, or those in lower Council Tax bands (A-D in England, A-E in Scotland and Wales). So, even if you don't receive benefits, you might still be able to tap into this support if your home could really do with an energy boost.
Will benefits affect eligibility?
If someone in your household does receive certain benefits, it often makes the path to a grant a bit smoother. It's about ensuring everyone has access to a warm, efficient home, regardless of their financial situation. Our friendly team can help you navigate this, making it simple to see if your benefits make you eligible.
Available funding schemes.
What types of insulation grants are available?
Loft insulation is just one step you can take. Depending on your circumstances, you might also be eligible for:
Cavity wall insulation.
Solid wall insulation.
Underfloor insulation.
Room-in-roof insulation.
You don’t have to know exactly what you need upfront, a qualified surveyor will help assess that.
How different schemes operate across the UK.
While GBIS is a national scheme, how other schemes are delivered can sometimes have regional nuances. For example, some local authorities might have specific "ECO4 Flex" routes, which allow them to identify households not on traditional benefits but still deemed vulnerable or at risk of fuel poverty. This means the eligibility criteria can be a little flexible depending on where you live. Don't worry though, when you check your eligibility with us, we'll help figure out which scheme, or combination of schemes, might be the best fit for your home and location. We work with these schemes day in, day out, so we're well-versed in the different pathways to getting your loft insulated.
Applying for a loft insulation grant.
Okay, so how do you actually get this grant and get that insulation installed? We've tried to make it as straightforward as possible.
Applying for a loft insulation grant with us is a pretty simple journey. Here’s a general roadmap:
Check your eligibility.
We've got a quick and easy online eligibility checker. It asks a few simple questions about your home and household to give you an initial idea of whether you might qualify. No need to dig out loads of paperwork just yet, just some basic info to get us started.
A friendly chat.
If it looks like you might be eligible, one of our advisors will get in touch. This isn't a hard sell, just a relaxed conversation to go through the details, answer any questions you have, and discuss the best options for your home.
Home survey.
If we both agree it’s a good fit, we’ll arrange for a qualified assessor to visit your home. They’ll take a look at your loft space, check what kind of insulation you already have (if any!), and confirm the most suitable insulation solution. They'll also make sure everything meets the grant scheme's requirements.
Installation day.
Once everything is approved, we'll schedule a time that works for you to get the insulation installed. Our team of professionals will then do the hard work, ensuring a smooth and efficient installation.
About the required documentation for the loft insulation application process.
When it comes to the nitty-gritty, you’ll generally need some paperwork to confirm your eligibility. This often includes:
Evidence of home ownership or landlord permission if you're a private tenant. If you rent, we’ll need to chat with your landlord about their contribution, as it’s usually required for grant applications.
Proof of any benefits received, if that's your route to eligibility. This helps confirm you meet the criteria for certain schemes.
Your home’s Energy Performance Certificate (EPC), if you have one.
We’ll guide you on exactly what’s needed, so you won’t be left scratching your head. Our aim is to make the application process as clear and smooth as possible, cutting through any potential red tape so you can focus on the exciting prospect of a warmer, more efficient home.
Choosing government approved installers.
This bit’s important! When you're dealing with energy efficiency improvements, you want to be sure the work is done properly and to a high standard. That's why government-backed schemes like GBIS require that the installation work is carried out by certified and approved installers.
We only work with TrustMark and MCS registered installers. Think of TrustMark as a quality stamp for home improvements. It means the installer has been thoroughly vetted and works to government-endorsed standards. MCS (Microgeneration Certification Scheme) is similar, specifically for renewable energy and energy efficiency technologies. By choosing an installer with these accreditations, you can have peace of mind, knowing that your loft insulation will be fitted professionally, safely, and to the highest quality standards. It protects you, the homeowner, and ensures you get the best possible outcome from your grant.

Cost implications and savings with loft insulation.
So, how much could you save with loft insulation? The savings can be pretty significant, and it's one of the most compelling reasons to get your loft insulated. The Energy Saving Trust estimates that a typical semi-detached home could save approximately £230 per year on heating bills by having 270mm first-time loft insulation installed. For a detached house, those savings could be even higher, potentially around £465 per year.*
Of course, these figures can vary depending on your home's current insulation, its size, the type of heating you have, and future energy prices. But the message is clear: insulating your loft is a fantastic way to keep more cash in your pocket, month after month, year after year. It's a long-term investment in your comfort and your finances.
Understanding the cost of loft insulation without a grant.
Even without a grant, loft insulation is considered one of the most cost effective home energy efficiency improvements you can make. The average cost of professional loft insulation in the UK for a standard home can range from approximately £300 to £1,000. This will depend on the size of your loft, the type of insulation material used (e.g., mineral wool, loose-fill, or rigid boards), and whether any preparation work is needed (like clearing the loft or addressing damp).
While it's an upfront cost, remember that it's an investment that typically pays for itself many times over through reduced energy bills. It's usually one of the quicker and less disruptive home improvement jobs too, often completed in less than a day! So, even if the grants aren't for you, the long-term benefits still make it a very worthwhile consideration for any homeowner.
Long term energy savings and efficiency benefits.
The beauty of loft insulation is that it’s not a short term fix; it's a gift that keeps on giving. Once installed, quality loft insulation can last for over 40 years, providing consistent energy savings throughout its lifespan. It doesn’t degrade quickly, meaning your home stays warmer, your bills stay lower, and your carbon footprint stays smaller for decades.
Beyond the immediate savings, an insulated loft also improves your home's Energy Performance Certificate (EPC) rating. A better EPC can be attractive to potential buyers if you ever decide to sell, adding value to your property. It’s about creating a more comfortable, more valuable, and more environmentally friendly home for the long haul.
