The BFRC (British Fenestration Rating Council) rate the thermal efficiency of windows as a whole from A to G, with A being the most efficient – an A+ rating can be given to windows with an extremely high efficiency level. To meet ‘Energy Saving Recommendation’ certification, the windows must be C-rated at the very least.
The more efficient a window is, the more it will help to keep the heat in your home and save you money on your energy bills. To increase the efficiency of your windows, you should consider installing energy efficient windows such as low emissivity windows.
Low emissivity, or low-E windows, can be as much as 40% more efficient than conventional double-glazed windows. Suspended between the panes of glass is a metal coating on a plastic film, making them ‘spectrally selective’. This means that they allow short wave radiation from the sun into your home, but don’t allow long wave heat radiation to escape in the opposite direction.
From the inside, the metal coating is very hard to spot with the naked eye but from the outside they can appear slightly mirrored.
Double-glazing is the name given to the windows with 2 panes of glass, rather than only having a single pane, which acts as an additional layer of insulation. To further add to the insulation, the panes of glass are separated by a gas, commonly argon. Replacing single glazing with double glazing can benefit your home in many ways:
Add a third pane of glass and you have triple glazing which is said to increase the benefits of double glazing further but does come at an additional cost.
In addition to double and triple glazing, you might want to consider secondary glazing. For homes with single-glazed windows, a secondary pane can be installed to the existing windows without the need for a full replacement.
Secondary glazing is typically less expensive than double glazing and while it’s similar to double glazing, in the sense that there are 2 panes of glass, they don’t tend to have the same level of energy efficiency.
You can further increase the insulation around your windows with heavy curtains or blinds.
According to the Energy Savings Trust, replacing single-glazed windows around a semi-detached home with A-rated double glazing could lead to savings of up to £155 a year on your energy bills.
Doing the same with A++ double glazing could save you up to £170 a year on your energy bills.
It’s not only the glass that needs to be considered but the window frame too. The various materials available all have different qualities and could help to increase the efficiency of your home.
uPVC window frames are an effective insulator, delivering your home with an extra layer of insulation, composite, wood and fibreglass frames all have these benefits too. This is in comparison to metal frames, such as aluminium, which is a poor thermal insulator. However, having a thermal break installed within aluminium frames will help to make them much more efficient.

When it comes to replacing the windows around your home, it could be easy to get put off by the cost but energy efficient replacement windows will help to save you money in the long run.
You should consider replacement windows if any of the following apply to your existing windows:
Installed A rated windows around your home will come at a higher price to less efficient windows but you could make back your initial investment through energy bill savings.
The total cost of a new energy efficient window will vary depending on the frame material, size and style of the window. uPVC is the cheapest window frame material in the UK, one of the main reasons why it’s the most popular, but they will need replacing sooner than aluminium, composite or timber windows.
The table below shows the potential cost per low-e window with double glazing, depending on the material you choose for the frame.
|Window frame material||Potential cost before installation|
|uPVC||£200 – £1,065|
|Aluminium||£260 – £1,390|
|Timber||£300 – £1,600|
A grant would help to cover the installation costs of energy efficient windows or double glazing but currently, there aren’t any government funded energy efficient window grants available in the UK. However, you might be able to earn funding for new windows through:
You might also want to find out if you’re entitled to a Home Improvement grant through your local authority, which exists to help cover the cost of repairing your home.
Whether you’re looking for new windows in Northern Ireland, England, or anywhere in the UK, you may be eligible for a new windows grant. Take a look at our guide to double-glazing grants to find out if you meet the eligibility requirements for the above schemes.
