Insulation is incredibly important if you want your home to be energy-efficient. Without adequate insulation, your heating system will have to work a lot harder to warm the house, making your energy bills much more expensive. But what areas of your home need insulation the most?


One of the main areas of your home that needs insulation is the loft space. If you don’t use the loft for anything other than the storage of non-perishable items, then you will be paying to heat the space unnecessarily if it is not insulated from the rest of the home. The loft floor can be insulated between the joists to stop the heat escaping from the main house into the roof area.


A lot of heat from the home escapes through the roof if it isn’t properly insulated. If you want the loft to serve as another liveable space, or you want to store anything in it that could be damaged by low temperatures or damp, then you will need to insulate the roof between the rafters. A lack of adequate roof insulation can also mean that damp and condensation can enter the home more easily.

Exterior walls

The exterior walls are another area of your home that needs insulation. Solid walls that are fitted with external wall insulation (EWI) can save homeowners up to 50% annually on heating bills, as well as reduce damp, condensation, and noise pollution. 

EWI also has the added benefit of providing a new look for your home included in the price, as the insulation system needs to be rendered after it has been installed. If the property has cavity walls, they should be fitted with cavity wall insulation first, but EWI can be applied for an extra insulation boost.

Floors over unheated spaces

Up to 10% of heat can be lost through the floor of a home that has no underfloor insulation. Floors above any unheated spaces, such as garages, porches or vented crawl spaces should also be insulated to prevent any unnecessary loss of heat.

Internal walls (optional)

Internal walls can also be insulated through the use of rigid insulation boards or by building a stud wall filled with insulation material such as mineral wool fibre. This type of insulation can sometimes be useful for sound dampening between rooms and helps to retain the heat better when you are only heating certain spaces at a time. The downside of internal wall insulation is that it reduces the size of the room.


Insulation should be the first improvement homeowners look to implement when it comes to making the property more energy-efficient. Knowing what areas of the home need insulation the most can help you to spend your money effectively and see the biggest savings when it comes to your energy bills.
