Keep the heat where it belongs
A poorly insulated loft is one of the biggest sources of heat loss within a home. Installing high-quality Loft Insulation is one of the quickest and most cost-effective ways to improve your property's energy efficiency, reduce heating costs and create a warmer, more comfortable living environment. Warmhouse Ltd specialises in professionally installed Loft Insulation systems for domestic, commercial and social housing projects throughout the UK, helping homeowners reduce energy consumption while improving comfort and long-term energy performance.

Benefits of loft insulation
-
Installing loft insulation can help to:
-
Reduce heat loss through the roof by up to 25%
-
Lower household energy bills
-
Improve your home's Energy Performance Certificate (EPC) rating
-
Create a warmer and more comfortable home
-
Improve thermal performance throughout the property
-
Reduce your carbon footprint

Loft Insulation works even more effectively when combined with external wall insulation, internal wall insulation, cavity wall insulation, flat roof insulation, underfloor insulation and air source heat pumps as part of a complete whole-house energy efficiency solution.
Suitable for most properties
Loft Insulation is suitable for most homes with accessible roof spaces and can be installed in both existing and newer properties. Warmhouse installs high-performance insulation systems using approved materials selected to suit your property and current Building Regulations. Every property is individually assessed to determine the most appropriate insulation type and depth, ensuring maximum thermal performance and long-term energy savings.
I live in Durham and cannot rate these people highly enough. I got funding through them with Durham Council for my external wall insulation and my guttering and downpipes. I work and didn't think I would be eligible but working didn't affect my eligibility.

How loft insulation works
Loft Insulation is normally installed between and over the ceiling joists, creating a continuous thermal barrier that significantly reduces heat escaping through the roof. By trapping warm air inside your living space, your home stays warmer for longer, reducing the amount of energy required to maintain a comfortable temperature. Professionally installed Loft Insulation is quick to install, requires very little maintenance and continues delivering energy savings for many years.
