Double Glazing Grants

The government’s green deal grant scheme ended in July 2015 after poor uptake due to high interest rates.

Most homeowners felt it was better to self-finance their double glazing as this would deliver a higher return on investment.

Until July 2015, homeowners were able to apply for a grant known as the ‘Green Deal’. This initiative was designed to encourage homeowners to make energy-saving improvements to their home, including installing double glazing.

The government provided funding to cover the cost of installation, meaning homeowners paid nothing upfront for their double glazing. Homeowners then paid back the cost of installation over several years using the savings they made on their energy bills.

However the Green Deal scheme was scrapped due to a lack of interest from homeowners, with only 15,000 houses signing up for the grant over three years. This was largely due to the high interest rates that were attached to the repayments, which made the grant very unpopular.

No scheme has yet replaced the Green Deal, and the government have not announced their intentions to put a new grant in place to help homeowners to install double glazing.

What are your Options now the Green Deal has Ended?

The UK government has introduced a newer scheme called the Energy Company Obligation (ECO), which provides grants to a small number of homeowners to enable them to make energy efficient changes to their home, such as installing a new boiler or internal wall insulation. Recipients of the grant need to be on a low income and/or receive benefits from the government.

The ECO scheme does not specifically offer grants for double glazing, but homeowners are sometimes able to put some of the money they receive for other home improvements towards installing double glazed windows. This is usually only for those who live in older properties with single glazing.

For homeowners in Scotland, it is worth checking whether you are eligible for a Home Energy Efficiency Programmes for Scotland (HEEPS) grant. This interest free government loan provides homeowners with up to £4,500 to install new double glazing into their home.

This loan is only available to those switching from single glazing to double glazing however, and not for those looking to replace their current double glazing. You must also be on a low income and/or receiving benefits from the government to qualify for a HEEPS grant.

If you are not eligible for government grants, you will have to self-finance your double glazing.

Can you Get Free Double Glazing?

Unless you qualify for a grant from the UK government, there is no free double glazing available. Instead, many double glazing installation companies offer competitively priced finance schemes that allow you to spread the cost over several years. This can help to make double glazing much more affordable.

Leading window companies such as Anglian, Everest and Safestyle offer finance agreements over 12 to 120 months. Below is a representative example of an interest-free finance option offered by Safestyle:

If you are on a budget, some window companies also have flash sales or discounts on their double glazing which can save you a lot of money. However, it can be difficult to know when these come and go. Signing up to a company’s newsletter or mailing list is a good way to find out when these special offers are running.

How Much can you Save with Double Glazing?

Installing new double glazing can cut your spend on monthly energy bills, saving you a significant amount of money every year.

Double glazed windows reduce the amount of heat that escapes from your property. This keeps your home warmer and reduces your reliance on central heating.

With energy prices having already risen by 60% over the last 10 years, now is the best time to install new double glazing in order to benefit from the cost savings.

The exact amount of money that double glazed windows can save you will depend on a variety of factors including how much energy your household uses and the energy efficiency of your new windows.

It is estimated however, that properties with single glazing that install new double glazing with an energy efficiency rating of A+ can save up to £110 on their energy bills each year.

The table* below shows you how much double glazed windows can cut your annual spend on energy bills in different sized properties, based on the energy efficiency rating of the windows:

Is Double Glazing Worth It?

The savings you can make on your energy bills is just one of the benefits that you can enjoy by installing double glazing. Other benefits include:

Your house will feel warmer with fewer draughts and cold spots, particularly in the cold winter months.

Double glazing will increase the overall value of your property.

Your home will feel quiet, as double glazed windows block out more noise from outside.

There will be less unwanted condensation build-up on the inside of your windows.

Your property will be more secure, since double glazing is tough and hard to break.

Installing double glazed windows is therefore a worthwhile investment, and one of the simplest ways to improve the energy efficiency of your home.
