Up to a quarter of your property’s heat may be lost through the roof if your home is not insulated effectively (Source: Energy Saving Trust). Insulating your loft can save you up to £240 per year* and contributions are available towards the cost of the installation via the Energy Company Obligation Funding. If your loft is used as living space, you should make sure it is insulated effectively. To do this, all areas of the space should be insulated including the sloping walls, any flat roof space left and any shared or party walls. Most of the time, this can be done by simply securing insulation boards in the space and utilising insulating plasterboard.
If you live in a house with cavity walls that are not insulated, you could be losing up to a third of your property’s heat through the walls (source Energy Saving Trust) which will increase the amount of energy you use to keep your home warm.
Insulating your cavity walls can save you up to £155 a year* and there may be contributions available towards the cost of this work via the Energy Company Obligation Funding.
Many houses built before 1920 will have solid walls, meaning there is no gap between the outer layers of the building. It is beneficial to insulate your solid walls wither through External Wall Insulation, or Internal Wall Insulation. This is because typically a solid wall will let through twice as much heat as a cavity wall (Source: Energy Saving Trust). Insulating your solid walls can save you up to £455 per year (Source: Energy Saving Trust).
If you chose External Wall Insulation, you can expect the insulation to be applied to the outside of your property, it is then skimmed and finished in an agreed style. If you chose Internal Wall Insulation, boards are applied internally to your walls, skimmed and then finished.
