At the same time it’s always worth checking out the various double glazing grants that may be available to you in the UK.

Finding these grants is often not easy and you may have to search around which is where we come in. We’ll let you know what may or may not be available right now and point you in the right direction to apply.

Double Glazing Made Simple


Double glazing, simply put, is a method of making a window with two layers of glass and a space between each layers. There is absolutely no doubt as to the benefit which is why these days over 80% of UK homes already have it installed. Here are just some of the benefits of good quality, properly installed, double glazing:

  • It Reduces Your Costs On EnergyEstimates from the Energy Saving Trust indicate that you can save as much as £12 a month if you install double glazed windows. That’s about £145 per year for the average detached home.
  • It Leads To A Reduction In NoiseNoise travels through solid particles such as air, solids and liquids. Your window insulates you against outside noise by providing a space between layers of glass that noise cannot travel through. This means that your home will be quiet and peaceful.
  • It Retains HeatHeat travels through the same particles as noise. This means that double-glazing your windows prevents heat from moving out of your home. This is especially important during winter. Likewise, double glazed windows prevent heat from moving into your home during hot seasons such as summer.
  • It Increases Your Home SecuritySecurity is critical in any home. Double-glazing your windows provides an additional security barrier to any would be intruder because such windows have two layers of glass. This makes your home a bit safer than conventional windows.
  • It Reduces Your Carbon FootprintLower energy consumption can only be good for the environment!

Forms of Double Glazing


forms of double glazingThere are various different types of double-glazing in terms of the materials used – the most common forms of double-glazing being as follows:

uPVC i.e. Unplasticized Poly Vinyl Chloride Frames: These frames are very durable as well as recyclable. They also require very little in the way of regular maintenance.

Wooden Frames: They require a bit of maintenance and regular painting but they are environmentally friendly and aesthetically pleasing.

Steel Or Aluminium Frames: These frames are built to last! They are durable, slim and recyclable.

Composite Frames: Two materials make up these frames i.e. plastic and timber or aluminium and timber. The use of timber means that these frames require a bit of maintenance but ultimately, the plastic or aluminium will reduce the need for extensive maintenance.

Possible Restrictions


Historic homes, homes in conservation areas and listed buildings are subject to a number of restrictions including what the property owners can do with their windows. You should choose from a number of available options that include shutters, heavy lined curtains, sealed blinds or secondary glazing.

It is important for you to note that the suitability of these options depend entirely on the restrictions the local council has placed on your building or home.

How to Cut Costs on Double Glazing


As mentioned earlier, double glazing is costly. You can cut costs on double glazing your windows by fitting:

  1. Secondary Glazing: You can fit a secondary layer of glass and frame inside the window reveal that already exists. Secondary glazing may not seal your windows perfectly but it is cheap and it saves energy.
  2. Hollow Blinds, Sealed Shutters And Heavy Curtains: The main objective of double-glazing is to reduce heat loss and energy costs. Heavy curtains can achieve this objective because they reduce the intensity of draughts flowing through your window. Sealed shutters and hollow blinds will also achieve the same objective.

The Green Deal – NOW CLOSED:

Great while it lasted! The UK government launched this particular initiative in 2013. The principle aim of the Green Deal was to make homes energy efficient. This deal provided grants of up to £10,000 per home. Business owners could qualify for grants that surpass this amount. The purpose of the grant was to install energy efficient products e.g. double glazed windows in your home and business.

Unfortunately Green Deal funding was unexpectedly withdrawn in July 2015 – Read More Here >>>

Double Glazing Grants 2021 – What’s New


double glazing grants 2019

This article has been updated in June 2021. Well … what a year 2020 was for us all and who could have seen THAT coming! And what a start to 2021 with a third UK lockdown being enforced. At last things are improving though and I feel it’s time to draw a line under it and look at the outlook for UK double glazing grants for the remainder of 2021.

We’re not out of the Covid-19 woods yet but, with the vaccine being rolled out so rapidly, one would like to assume that we’re starting getting back to a degree of permanent normality in H2 2021. And that means there’s likely to be a very high focus on economic recovery. In turn this means we may see a variety of measures and incentives introduced to kick-start to economy.

Let’s not forget Brexit too – that’s out of the way now and we all know where we stand!

Will this mean that a new dawn of double glazing grants 2021 are a real possibility … don’t hold your breath! Read More about the outlook for double glazing grants over the remainder of 2021.

Green Homes Grant Scheme

The Covid-19 “false dawn” easing of restrictions following the first wave being brought under control saw the Government launch a brand new initiative called the Green Homes Grant Scheme.

This was designed to support in two ways:

  1. To support the drive to net zero greenhouse gas emissions by 2050.
  2. To help kick-start the economy by providing a boost to the construction and home improvements industry.

There was much lobbying by the double glazing industry to make sure it was included within the list of applicable energy efficiency measures detailed within the scheme.

The scheme was launched in September 2020. In a nutshell it allowed homeowners and landlords to apply for free vouchers of up to £10,000 (£5,000 in most cases though) which can be used towards the cost of certain energy efficient home improvement measures.

When business secretary Alok Sharma finally announced the scheme it was good and bad news for the double glazing industry. The good news was that double glazing grants were available through the scheme. The not so good news was that it was classed as a secondary measure and only covers an upgrade from single to double glazing. That said, if you fitted the criteria there’s a free money double glazing grant to be had!

Update June 2021

The scheme itself was for England only and initially designed as a short term scheme with measures needing to be installed by the end of April 2021. This was then extended to run up until 31st March 2022. We published a feature explaining all you needed to know: Double Glazing Grants 2020 And The Green Homes Grant.

Then came the bombshell! Rumours began circulating in March that the Governments is to pull the Green Homes Grant completely. Initially these were denied with Government sources stating that it was going to stay in place until 2022 but with reduced funding. However, an 11th hour u-turn and the scheme ended almost immediately on the 31st March 2021 – a year ahead of schedule. No applications were therefore be accepted from 1st April 2021.

On a positive note the £300m allocated to the scheme 2021/22 has been re-allocated to local authority led home improvement schemes which will mainly target low income households. Read our feature Double Glazing Grants – The Green Homes Grant Axed.

Industry Outlook

The building industry as a whole has gone ballistic. It seems like the whole country is wanting to get those projects started now that we can again. Major new build, social refurbishment along with home improvements and DIY … it’s all happening at once!

As a result of demand and the impact of the pandemic certain materials are in short supply – particularly timber, steel, cement, paint and chipboard at the moment. Certain raw materials are in short supply also which means that prices have risen significantly. Add this to the fact that most reputable builders have full order books and enough work to see them through the next six months or so and you’ll begin to understand that if you’re thinking about double glazing it’s still worth getting the quotes but you may want to consider delaying until the supply chain calms down later this year.

Double Glazing Grants 2021 – What Else?


double glazing grants 2021 ukThe Green Deal is long gone as a Government funded initiative – it closed back in 2015. However the program has been taken over by a privately funded organisation. This company provide loans for certain energy saving measures (including double glazing) on a similar basis to the original program so is worth considering.

Loans and borrowing are still at highly competitive rates and so an unsecured loan or increase on the mortgage may work out a great option for you. Many of the double glazing manufacturers and installers are offering some very attractive deals and finance packages so it could be a good time to buy. Check all the options and consult a finance expert before deciding.

As mentioned above, the Governments own ECO3 program launched in December 2018 and continues until at east 2022. This is primarily for low income and fuel poverty families.

Better double glazing grants options are available if you’re living in Scotland under the Home Energy Efficiency Programmes Scotland (HEEPS). The HEEPS program consists of 4 specific schemes: Area Based Schemes or ABS, Warmer Homes Scotland, Home Energy Scotland Loan Scheme and an Equity Loan Pilot Scheme.

Window Scrappage Schemes: 

Currently many of the main double glazing companies provide a scheme whereby you can trade in old windows for a reduced cost or cash-back on replacement, energy efficient windows. Read more about Windows Scrappage Schemes here >>>.

Scotland, Wales And Northern Ireland: 

The Scottish government wants to reduce CO2 emissions and energy bills. This is why it now offers interest free to households seeking to undertake certain improvements in their homes such as double-glazing. These improvements must lead to greater energy efficiency as does double-glazing. Similar schemes in Wales and Northern Ireland are also under consideration.
