Did you know that if you insulate your home you could benefit from a warmer home and save money on your energy bills? According to the Energy Saving Trust, loft insulation could save £10-225 per year, cavity wall insulation could save £70-225 per year, or solid wall insulation could save £120-425 per year, the savings will vary depending on your property.
Some households may be eligible for free insulation if someone living in the property is in receipt of certain benefits as there are grants available to cover or contribute to the cost of insulation. Use our home insulation grant checker to see if you are eligible.

Loft insulation

If you haven’t been in your loft for a while it might be worth having a quick look to see how much insulation is in there. If it’s less than 100mm of insulation you should consider getting it topped up as the current recommended level is 270mm. You can install loft insulation yourself but this is not advisable due to the health and safety risks which include ensuring that any electrical wiring is safe and that there is adequate ventilation to prevent condensation. We can help you find a local installer who can assess your needs and install the most appropriate insulation safely with an industry-backed guarantee.
If your loft has been boarded out then you may have insulation underneath the boards, and unless you want to remove all the boards then your loft won’t be able to be insulated.

Wall insulation

There are many types of wall insulation which cater for different wall types. A lot of UK properties built after 1932 are cavity wall construction and therefore are able to be filled with insulation. Cavity wall insulation is installed by drilling a hole in the wall between the bricks and blowing the insulation material into the cavity. Properties that were built after 1990 are likely to have been built with insulation in the walls.

Solid wall and non-standard construction properties are generally unable to be filled with insulation but they can still be insulated either internally or externally. Internal insulation is a very intrusive form of insulation as it requires moving all fittings on the externally facing walls in order to apply insulation boards and material, which also reduces the size of the room. External insulation is less intrusive but involves layering insulation boards and render to the outside of the property. This doesn’t only insulate your property but gives it a facelift too. There are many decorative finishes available such as classic render, pebbledash, and brick effect. External insulation does require permission as well as building control sign off after completion.

Checking for suitability

It is important that you get professional advice about whether your property is suitable for insulation and that you seek any permissions that are required before work commences. Wall insulation inspections can involve inserting a borescope into the wall to check for any issues or existing insulation. We can help you find a local installer who is a qualified installer who is registered with the NIA, CIGA, or BBA that can check your walls and install the most appropriate insulation. They will also provide you with an industry-backed guarantee (CIGA for cavity wall and SWIGA for solid wall insulation).

Checking insulation quality

Once insulation has been installed it is advisable to have the insulation checked by a qualified and registered professional (as per above), especially if you are experiencing issues with heat loss, damp, or condensation. The causes of these could be due to deterioration of old insulation material, inadequate ventilation, gaps in the insulation, or debris in the cavity. If you require your insulation checking, let us help you find a local installer who can investigate the issue and check on any guarantees to help with the cost of repairs.
With so many insulation options open to you and the potential savings that you can make, it’s worth investigating what can be done to make your home warmer and cheaper to run especially with rising energy bills.

Most homes are suitable for one form of insulation or another depending on your wall type and the condition of your loft, but often different rules apply on whether you are able to insulate your walls depends the product being used, wall type and condition.

 

Loft insulation

It is worth having a look in your loft to see if it is already insulated or can be insulated. It is recommended that you have 270mm of loft insulation and it is worth topping it up if it’s below 100mm. If your loft is converted, boarded or the loft hatch is inaccessible it won’t be suitable. You can either insulate the loft yourself or get an insulation company to do it.
Cavity wall properties
Distinguishing whether your walls are cavity construction or solid is determined by the brick pattern. If the bricks are in a regular pattern length ways throughout the wall then it is likely to have a cavity. If the walls are covered then you can measure the width of the wall and if it is over 260mm then it is likely to have a cavity. Those with a cavity wall construction should be able to be filled with insulation. An insulation company will do a survey prior to filling the cavity and will put a borescope into the wall to check if it’s already filled with insulation and clear to fill it.

Solid wall properties

To determine if the walls are solid, check the brick pattern, if they form an alternating pattern then the wall is solid. Solid walls can still be insulated but they can’t be filled and would have to be internally or externally insulated. Internal insulation will reduce the size of your rooms and would be disruptive. External wall insulation is less intrusive but does require additional checks with the council.

Non-standard construction

If you live in a timber or steel-framed property, stone property or pre-fabricated property then they are unlikely to have a cavity in them or if they do they are probably not able to be filled. Some of these build types can be treated the same as solid wall properties, however, different planning rules may apply and you should seek expertise advice on whether the property is suitable. In particular, in the case of stone properties these are often prohibited from having external wall insulation by some councils as it changes the look of the property.

Savings

If you are able to insulate your home you could save between £10-225 per year with loft insulation, according to the Energy Saving Trust, this varies depending on the size of the property and how much insulation is already present. Cavity wall insulation could save you £70-225 per year and solid wall insulation £120-425 per year depending on the size of the
property.
It is also worth checking if you are eligible for free insulation as people who are in receipt of certain benefits are eligible for grants to cover or contribute to the cost of insulating their home.
