Fill in the form above to receive bespoke double glazing quotes


There are countless benefits to getting double glazed windows for your home. It's great at reducing noise, plus you can add an extra layer of insulation to keep the heat locked in – which also acts as an extra layer of security to keep intruders out.

Despite all these benefits, some homeowners struggle to cover the initial costs of double glazing. Thankfully, there are ways to bring this price down – with government grants being one of the key support systems. Although there are no grants for double glazing specifically, there are a handful of environmental grants that do include the installation of double glazed windows.

We’ll guide you through your different options further down this page. If you don’t qualify for any double glazing grants, however, you can still find the best deal by filling in this form to receive quotes from local installers.

Can you get double glazing government grants in 2021?


Unfortunately, the UK government’s Green Deal scheme was scrapped back in 2015. With this scheme, homeowners could receive government grants for installing energy-efficient double glazing, as well as a host of other environmentally-friendly improvements.

Thankfully, the government released a new scheme this year called the Green Homes Energy Grant. This plan has dedicated £2 billion to help push the UK’s housing market in a more eco-friendly direction.


What is the Green Homes Energy Grant?

Available to all homes in England, the Green Homes Energy Grant can help you cut your energy bills and carbon emissions, covering two-thirds of the cost of home improvements, up to £5,000. Households that receive income-based or disability benefits can even get 100% of their home improvement costs covered, up to £10,000.

Improvements could include insulating your home, upgrading windows with double glazing, or even adding solar panels.

To be eligible for the Green Homes Grant, you must:

  • Own a home (includes long-leaseholders and shared ownership)
  • Own your own park home on a residential site (includes Gypsy and Traveller sites)
  • Be a residential landlord in the private or social rented sector (includes local authorities and housing associations)

You should also note that you won’t be eligible for the Green Homes Grant if you live in a newly built home which has not been previously occupied.



Is the Green Homes Energy Grant available in Scotland?

Unfortunately, the Green Homes Energy Grant only covers homes in England. If you live in either Scotland or Wales, fear not, you still have some excellent options on offer that can financially support in making your home more energy efficient. We go into this in a little bit more detail further down the page.


What are your options now the Green Deal has ended?


Energy Company Obligation

Unfortunately, if you live in England, you’ll struggle to find a double glazing grant.

However, there are other options. If you simply want to make your home warmer and better insulated – two of the main benefits of double glazing – then you should check whether you qualify for the Energy Companies Obligation scheme (ECO).

Since the government started ECO in 2013, companies all over the UK have been legally obligated to supply low-income homes with heat-saving methods, including free boilers and free wall and loft insulation.

If a company is large enough, it is compelled to install the equivalent of up to 35,000 heating systems per year, and has to ensure that 15% of the households it helps are in rural areas.

None of these replacement boilers can use coal – the most polluting fossil fuel – and because of this focus on the climate, ECO has so far reduced carbon emissions in more than 850,000 homes.

But if double glazing is your priority, you can just complete this form to receive quotes from specialists in your area.

Welsh Government Warm Homes Nest Scheme

Wales’ government doesn’t currently offer double glazing grants either – but again, you can get help with other home improvements which will keep you happy and warm.

Created in 2011, Nest has assisted more than 33,600 Welsh households in installing energy-efficient home measures, according to government statistics.

In 2017/18 alone, the scheme provided support to 4,600 homes, by helping people to afford new boilers, central heating systems, and insulation.

You may be eligible for Nest if:

  • You’re a homeowner, or you rent from a private landlord
  • Your home wastes energy and is unnecessarily expensive to heat
  • Someone in your household receives a means-tested benefit
  • A member of your household has a chronic respiratory, circulatory, or mental health condition, and a low income

The means-tested benefits which qualify are:

  • Child Tax Credit
  • Council Tax Reduction
  • Housing Benefit
  • Income-based Jobseeker’s Allowance
  • Income-related Employment and Support Allowance
  • Income Support
  • Pension Credit
  • Universal Credit
  • Working Tax Credit

Housing Aid for Older People Scheme

For all you Irish readers, this government programme may be your ticket to a double glazing grant.

The Housing Aid for Older People Scheme is aimed at people in the country who are 66 or older, and living in substandard housing conditions.

However, if you’re staying in dangerously inferior accommodation, your local authority may offer you help even if you’re under 66.

Your grant can cover any or all of the following:

  • Repaired or replaced windows and doors
  • Structural improvements
  • Dry-lining
  • The provision of water and waste management services
  • Heating
  • Cleaning
  • Painting
  • The reduction of radon levels
  • Rewiring

This isn’t an exhaustive list, either. If more work is considered necessary to get your home up to the standard you deserve, you could enjoy further benefits.

The highest grant handed out under the scheme is €8,000 (£6,700), which can cover as much as 95% of the cost of improvements made to your home.

You can claim the 95% grant if you have an annual household income under €30,000 (£25,140).

That percentage figure declines if you and the people you live with earn more, all the way down to 30% for households with an annual income of €50,001 to €60,000 (£41,930 to £50,310).

Double glazing for Scotland


Unfortunately, there are currently no grant schemes available in Scotland to help make double glazed windows more affordable. Some homeowners looking for ways to save energy around the house might find HEEPS useful. This scheme was launched by the Scottish government in 2013, helping homeowners install insulation and efficient boilers more affordably.

HEEPS helped more households in 2017/18– around 15,500 – than the UK government’s Green Deal assisted in its entire run.

In total, 27,734 energy efficiency measures were put in place in 2017/18, according to the Scottish government – at a cost of £116.85m.

Just over two-thirds of those improvements came in the form of insulation, while the rest were in heating.

Did You Know?

You can save more than £400 each year, just by switching your home’s energy supplier. If you’re looking to cut down your bills, this one’s a bit of a no-brainer.

That’s why we’ve partnered with Switchd. With four different price plans (including a free option), Switchd will find you cheaper, greener energy suppliers in no time.


How much can you save with double glazing grants?


Getting double glazing installed can save you up to £155 per year on your energy bills, whilst also boosting a property’s value by as much as 10%. For most of these grants, the amount you save on the initial costs will depend on where you live, the size of your property, and the type of windows you go for.

However, whichever grant you go with, it’s sure to cut down the price substantially – after all, double glazing costs £640 per window, on average, with professional installation adding another £250.

The UK government is currently pushing homeowners to opt for the Green Homes Energy Grant. As we mentioned earlier, with this grant, you can attain a voucher for two-thirds of the cost of your eco-friendly installations, capped at £5,000.

This means you can arrange for home improvements worth up to £7,500, and still have two-thirds of your spending subsidised. So, if your installations cost more than £7,500, you can still get a £5,000 voucher – you’ll just pay more yourself.

We’ve created a graph below that shows roughly how it’ll pan out for you, depending on which home improvement you choose.





While the Green Deal may have ended, there are still many ways to improve your home with double glazing. And, with the UK government practically splashing the cash with the Green Homes Energy Grant, it would be rude not to take them up on their offer, really.

If you don’t live in Scotland or Ireland, just contact your local housing authority to see what they can do for you. There are also numerous other schemes and grants to help people with serious health conditions or disabilities, those of advancing years, or those who are in immediate need of repairs.

If you don’t qualify for any of these grants, simply complete this form to receive bespoke quotes from local double glazing professionals.
