Loft Insulation 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.

All of our Loft Insulation installs come with a minimum 2 year guarantee.
Loft insulation works by trapping heat within your home, preventing it from escaping through the roof. Insulation materials, such as mineral wool, are laid between and over the joists in your loft, creating a thermal barrier. This barrier reduces heat loss, keeping your home warmer in the winter and cooler in the summer, ultimately improving energy efficiency and lowering heating costs.
What a brilliant scheme!
A representative contacted me via a door to door campaign and I thought it was too good to be true. However, I received wall insulation (house is so cosy now), air source heat pump and solar panels – they even did my loft. All the tradesmen were lovely and really good at their jobs. Rhys was so helpful and explained everything to me. The office staff were also lovely and project person rang me all the time to check everything was okay. Thanks you Smart Energy Homes 🙂

Here are some commonly asked questions about Loft insulation, if you can’t find the answer to your question here please done hesitate to get in contact with us.
Loft insulation involves placing insulating material between and over the joists in your loft or attic space. This material acts as a barrier to heat loss, helping to keep warmth inside your home during winter and preventing it from getting too hot in the summer.
On average, loft insulation can save you up to £340 per year on energy bills, depending on your home’s size and energy usage. These savings come from reducing the amount of heat that escapes through your roof, allowing you to use less energy to heat your home.
Loft insulation typically lasts for over 40 years, and during this time, it should pay for itself many times over in energy bill savings. The material does not degrade quickly, meaning it will continue to provide benefits for decades with little to no maintenance required.
While it is possible to install loft insulation yourself, it’s often recommended to have a professional do the job. This ensures that the insulation is installed correctly, safely, and to the right specifications, maximising its effectiveness and avoiding issues like gaps or compression.
No, loft insulation is designed to keep your home comfortable year-round. In the summer, it helps to prevent excessive heat from entering your home by blocking it from the roof, keeping indoor temperatures cooler.
The recommended depth for loft insulation is typically around 270mm (10.5 inches) for optimal performance. If your existing insulation is thinner than this, you may need to top it up to reach the recommended level.
Properly installed loft insulation should not cause damp or condensation. In fact, it can help prevent these issues by maintaining a consistent indoor temperature. However, it’s important to ensure your loft is adequately ventilated to allow moisture to escape and avoid any potential problems.
Yes, there are government schemes, such as ECO4, that provide funding for loft insulation and other energy efficient measures. These programs aim to improve energy efficiency in homes, and you may be eligible for free insulation through it.
