Loft insulation

Reducing Energy Bills with Loft Insulation

Loft insulation is a quick and easy way to keep your home warm and reduce energy bills. It is also one of the lower-cost energy efficiency measures you can install in your home. As much as a quarter of the heat of an uninsulated home is lost through the loft and roof, but this can be easily prevented by ensuring your loft is adequately insulated.

Recommended Amount of Loft Insulation

Building regulations now require insulation to be around 10-12 inches thick or a depth of 270mm. If your home was built before 1982 and has not had an insulation top-up, it is recommended that you consider enquiring. During a survey, an assessor will make recommendations based on the assessment if you are unsure about how much insulation you currently have.

How Long Does Insulation Last?

Insulations should last around 40 years, paying for itself many times over its lifespan.


Loft has numerous benefits, including savings on energy bills, a warmer home in winter and a cooler home in summer, improved living conditions that are vital to health and wellbeing, reduced carbon footprint, and reduced noise pollution.

Savings on Energy Bills:

According to the Energy Saving Trust (EST), insulating a gas-heated detached home with a totally uninsulated loft could save up to £590 per year on energy bills. This estimate is based on the current fuel prices as of October 2022.
