Loft insulation is the most commonly known forms of insulation in the UK and a popular and effective way to improve the energy efficiency of a home. It involves adding layers of insulation material to the floor of the loft space, which helps to reduce heat loss through the roof and keep the home warmer in winter. 

There are several materials that can be used for loft insulation, the most widely used being mineral wool. The insulation material is laid between the joists, with additional layers added to achieve the government recommended amount of 270mm. 

A typical Loft Insulation Installation could take between 1-2 days

Save Money

Ensuring your property is correctly insulated can save you loads of money each year on your energy bills.

Fully Qualified

All of our installers are fully qualified and accredited ensuring you get the best install available.

Ventilation Included

Clean air is essential for healthy living and for preventing damp and mould. With every install of insulation we assess ventilation and install any needed upgrades.

Lower Your Emissions

Insulation reduces heat loss which removes the reliance on gas or electric heating, reducing your carbon footprint.

According to a survey taken by the Energy Saving Trust an average detached house could look to save £590 per year by insulating an uninsulated loft with 270mm of loft insulation.

Why insulate a loft?

A quarter (25%) of all heat in your home escapes through the roof, by adding insulation you’re creating a thermal barrier making it harder for that heat to escape (almost like putting a hat on your house). 

By reducing heat loss your house stays warmer for longer, it also reduces the amount your heating system has to work to reach its set temperature, this cuts down on the amount of energy you use and helps you save money on your energy bills.

Recommended amount of loft insulation

The recommended amount of loft insulation in the UK is 270mm thick. Though lofts are a common place to store all those items you don’t want around the house all year round, it is vital you don’t condense loft insulation by placing items directly on top as this can reduce how effective the insulation is. Instead it’s recommended to install loft legs with loft boards above the insulation and place any items on these.

Frequently Asked Questions (FAQ's)

What is loft insulation?

Loft insulation refers to the process of insulating the space between the roof and the ceiling of a building to reduce heat loss and improve energy efficiency.

Why is loft insulation important?

Loft insulation helps to prevent heat from escaping through the roof, keeping the interior of the building warmer and reducing the need for excessive heating. It can also help to lower energy bills and reduce carbon emissions.

What types of insulation materials are commonly used for loft insulation?

The most common material used for loft insulation is  mineral wool (such as glass wool or rock wool).

How is loft insulation installed?

Loft insulation can be installed by laying insulation material between and over the joists in the loft space or by insulating the roof itself, depending on the type of roof construction. It’s important to ensure proper ventilation is maintained to prevent condensation issues.

How much insulation should be installed in the loft?

The recommended depth of loft insulation varies depending on the insulation material used. As a general guideline, a thickness of 270mm (10.6 inches) is often recommended for mineral wool insulation.

Can I install loft insulation myself?

Loft insulation can be installed as a DIY project, but it’s important to follow safety guidelines and instructions provided by the manufacturer, but when you can have it installed for free along with other energy efficient measures why would you want to install it yourself?

Will loft insulation cause dampness or condensation issues?

Proper installation of loft insulation should not cause dampness or condensation issues. It’s important to ensure that the loft space is adequately ventilated to allow moisture to escape. Additionally, insulation materials with suitable vapour permeability properties can help manage moisture effectively.

Under ECO4 all energy efficient measures installed include a ventilation assessment and upgrade. 

Is loft insulation suitable for all types of roofs?

Loft insulation can be installed in most types of roofs, including pitched roofs and flat roofs. The specific installation method and insulation material may vary depending on the roof construction.

How long does loft insulation last?

Loft insulation is designed to last for many years, often exceeding 40 years. However, the lifespan can vary depending on the quality of installation and the insulation material used. Regular inspection and maintenance can help ensure its effectiveness over time.

Can loft insulation be removed or replaced?

Loft insulation can be removed or replaced if necessary. In some cases, if insulation needs to be upgraded or if there are moisture-related issues, it may be necessary to remove and replace the insulation.
