Should I bother with loft insulation?

The cost saving benefits of loft insulation are pretty well known. There are also other factors to consider such as your health and your loved ones. Also, there are some issues with you may not think about or just have not come across before.

Do I really need insulation in the loft?

The answer to this is quite simple. If you have a loft then yes, you definitely do need insulation. Many homes already have some kind of insulation; however, the UK government recommends a minimum insulation thickness of 270mm (which is basically the same size as a 30cm ruler). Many of us will find a thinner insulation than that so it’s worth checking yours. Also, some of these homes have the right thickness but it is getting squeezed by all the stuff that gets dumped in the loft!

Benefits of loft insulation

Having the right type and amount of loft insulation can bring lots of benefits for you and your property:

  1. Save some money on energy bills

This is the most attractive benefit. Improved insulation in your attic will save money. A poorly insulated home can lose a quarter of the heat through the roof. So, the simple solution is to install adequate insulation. If the insulation is a recommended thickness of 270mm then you can save up to 25% on your energy bill.

  1. Good insulation increases the value of your home

Improving the energy efficiency of your home makes it more valuable. Making energy-efficient improvements to your home can increase its value by 14% on average.

  1. Insulation can improve your health

Poorly insulated lofts and those in which the floor is laid in the wrong way could cause moisture and condensation. Mould is then a risk, along with humidity, which means you are more likely to have breathing problems, respiratory infections, allergies or asthma. If you think you have a damp problem then it can affect your health or other family members.

Problems often arise when the insulation stuck down on the loft floor is not installed correctly. That will stop the air flow between the floor and insulation. This can then lead to problems such as:

Loss of thermal insulation efficiency

Strain on the ceiling

The resulting water vapour rises in house until it hits the cold surface of the bottom floor of the loft

This can cause condensation to form in isolation

Condensation then began to seep down creating moisture which affects the ceiling.

If you are looking to use your loft space for storage, adequate air flow is very important. It should be seen as an absolute necessity.

Don’t forget the areas around any recessed lighting in the loft can sometimes bring draughts, which will negate the benefits of insulation. For Downlight Covers, visit a site like

  1. It helps our environment

A detached house with proper insulation can reduce CO2 emissions by 80 kg per year. Reducing emissions of CO2 will mean you help do your part to reduce global carbon emissions and, therefore, the effects of climate change.

  1. Reduce the wear-and-tear on your boiler

If your boiler is working flat out and pumping out more heat than necessary and then chances are it won’t last long enough. Having proper insulation in your loft means that you will create a consistent environment in your home. This will help extend the life of your boiler which is another way you can save money on expensive repairs or replacement.
