Your loft insulation

With new energy savings solutions today, energy losses can be limited and can allow the transfer of heat between two closed environments. These methods allow to enjoy perfect temperature in your home. On average, you could save up to £180 a year, which even with the minimum 50% loft insulation grant would mean that you would save money within approximately 1 year of getting the loft insulation fitted. Help to reduce the irreversible effects that we’re having on the environment and get your loft insulated in order to reduce your home’s carbon footprint.


The loft insulation

At a time where house prices are rising, one should take advantage of each available space in a house. The attic can become an habitable space but it must be well insulated beforehand. The insulation of the loft consists in insulating the walls and the roof of the attic to reduce heat loss and sound troubles.
In order to make your home more energy efficient, it should be well insulated especially in the attic. There are many techniques of insulation and materials allowing to enjoy a good level of Interior comfort. The choice of method depends on the surface to isolate, so, before starting the work, you should enquire about the various insulating materials offered on the market and identify their specificities. In addition to the materials there are several methods that allow to perfectly isolate the lofts.

The benefits of loft insulation


  • reduce gas & electricity bills
  • reduce your home’s carbon footprint
  • keep your house warmer in winter
  • keep your house cooler in summer
  • prevent internal condensation
  • improve your home’s energy efficiency rating
  • reduce noise from outside (e.g. Traffic)


The attic insulation allows you to transform the space into a living area. It also provides nice savings in terms of energy consumption. Indeed, nearly 30 percent of heat loss comes from the roof. By choosing to insulate the attic, you are making savings on your energy bill.
The thermal insulation of the loft would to reduce the heat loss by up to 27%. The gain on the energy bill varies according to the source of energy used. For gas, it is approximately £450 per year, close to £530 for electricity. Professionally installed loft insulation for a typical three-bedroom, semi-detached house with gas central heating costs around £300, and would take less than two years to pay for itself through the savings you’ll make on your heating bills.

The cost of the loft insulation

The cost of the loft insulation depends on several factors namely the surface of the attic, the height, but also the place where you live. Observed prices are around 15 to 80 pounds per square metre.
The thermal insulation is a crucial step in the energy efficiency strategy. And given that the Government is currently campaigning for energy efficiency, it proposes more aid to individuals wishing to do eco-work related to thermal insulation. The amount of these subsidies depends on the nature of the project, the instigator of the project and the geographical location of construction resources. You can insulate between the joists with mineral wool and then lay rigid insulation boards on top, with wooden boarding on top of that. You can buy insulation board pre-bonded to floor boarding to make the job easier. Or you can raise the level of the floor so you can fit enough mineral wool beneath the new floor level.

Not just for the winter

In summer, insulation also helps maintain your loft cooler and longer, blocking hot air circulating under the insulation blanket which can reach 70 ° C. This is because insulation traps air inside, warm in winter and cool in summer. This slows down the speed the outside temperature affects your house. The bigger the temperature difference between the outside and the inside of your house, the more insulation you need. The airtightness of the loft in the summer is very important the as it prevents hot air to enter the attic. You can greatly improve the comfort in your attic in the summer by air flow to ventilate at night (gain of 1 to 4.5 ° C by ventilation). On hot sunny days your loft insulation will act as a barrier preventing the heat from your roof entering into your bedrooms, meaning cooler rooms and a better night’s sleep!

Your Energy Performance Certificate

Insulate your loft and reduce your overall energy consumption, it will improve, in fact, the value of your home and in may be an additional argument in selling it. You may be aware that all properties that are put onto the market for sale or rent now require an EPC (Energy Performance Certificate), which shows how energy efficient a property is. Having loft insulation installed to the recommended level can vastly improve your property’s energy rating, which could make the difference between selling / renting your property and it staying on the market (because with rising energy costs any new occupier will want to know that their money isn’t just going straight through the roof).
It is also widely speculated that a property’s energy rating will be used to determine future council tax bills – just like how the road tax for a car is partly based on the emissions it produces. So getting your loft properly insulated now could also potentially reduce your council tax bills in the future!
