This is thanks to the thermal barrier created from a double glazing unit a traps heat inside your home and prevents it from escaping through your windows. There are several other benefits to installing double glazing that you can also enjoy year-round.

The total costs of new double glazing can become unaffordable for many homes in Wales. This is where government grants for windows can help. In this case, you may be happy to know that there’s a UK-wide government scheme designed to improve the quality of housing for those that need it most.
ECO4 (Energy Company Obligation Scheme)
Launched in April 2022, ECO4 is the fourth iteration of the UK government’s Energy Company Obligation (ECO) scheme. Until March 2026, any recipients of certain means-tested benefits, including Income-based Jobseekers Allowance, Universal Credit, and Income Support, can get free energy efficiency improvements made in their home.
These upgrades are provided by energy companies with over 150,000 domestic customers and aim to alleviate fuel poverty among the UK’s lowest-income households. Double glazing replacement is included among the potential energy efficiency improvements that could be made under the scheme.
Warm Homes Nest Scheme
While the Welsh government’s Warm Homes Nest Scheme does not include double glazing replacement, the scheme is designed to improve energy efficiency by upgrading your heating systems and other forms of insulation.

Since April 2002, all replacement glazing in the UK must adhere to certain building regulations, related to thermal performance, safety, ventilation, and means of escape.
A professional installer should be registered with a competent person scheme, such as FENSA accreditation. This means they are qualified and obliged to ensure your windows installation meets such regulations. You’ll also receive a certificate that confirms compliance at the end of the installation process.
Thermal heat loss
Building Regulations in Wales stipulate that new windows and surrounding framework must have a maximum U-Value of 1.4W/m2K or minimum Window Energy Rating (WER) band B. U-Values measure the amount of heat that can pass through an object. This means the lower the U-Value of a window, the less heat will pass through it.
Homes in ‘critical areas’, where break-ins or breakages are more likely (for example, ground floor windows), are required to be fitted with toughened or laminated glass to help prevent this.
This applies to your replacement windows if:
In kitchens, bathrooms, or rooms where a lot of steam is produced, extra ventilation is required via windows and doors. Generally, the extent and form of ventilation are decided by the size and function of the room. Some rooms may only require less drastic ventilation measures such as trickle ventilators.
To prevent fire from spreading between properties, windows may need to be fire-resistant or fixed shut. This mostly applies to those in “unprotected areas”, where the fire resistance of the walls, doors, and windows is reduced or undetermined.
Means of escape
As a rule, new windows should provide the same potential for escape as the windows they are replacing. This means they should be the same size or larger unless the original windows were larger than necessary in terms of escape potential. However, all new windows must still meet the following minimum requirements:
Window regulations in rented properties follow the same guidelines as those listed above. However, if you live or are moving to a rented property, you may also like to know about some specific window-related requirements that your landlord is obliged to carry out.
These measures help to ensure that conditions in the property are ‘fit for human habitation’ and are enforced by the Welsh Government.
The presence of mould or fungal growth, caused by dampness or high humidity, can be tackled via damp proofing the area around windows and doors and ensuring that there’s sufficient means of ventilation without the need to always have to open the windows.
Poorly insulated homes can become very cold and unpleasant over winter. Landlords are therefore tasked with ensuring that all windows are properly sized and fitted.
Overheating can become an issue in properties with poor ventilation or those with a lot of south-facing glazing. In this case, shutters or blinds can be installed to help cool the property during the summer months.
To prevent break-ins, all window locks and deadlocks must be operating smoothly, otherwise, your landlord is expected to replace them.
Your windows should allow plenty of natural light. This means they should be sufficiently positioned and sized so that eyesight is never strained during the daytime.
There should be adequate means of escape from all parts of the building- that includes through doors or windows that are not too high up a building.
