Floor insulation (solid floor)

Priority for Completion: Very Low

This recommendation is triggered if the property has solid external floors and it is not expected that they have been insulated. The exact benefit will depend upon a wide range of factors including the heating systems, the cost of the fuel used, the occupancy of the home and the size of the floor area. Generally, the more the home is occupied and the larger the floor, the bigger the savings will be. However, changes to your home's solid floors are very difficult to implement, often require substantial financial investment and are likely to need professional tradesmen. This type of work is usually only worth undertaking on empty properties or when substantial alterations are being carried out. As a result we have rated this as being very low priority.

What is solid floor insulation?

People are often surprised by the amount of heat that can be lost through a building's floors. Modern homes have well insulated floors but older homes rarely do.

In the case of solid floors, insulation is usually fitted as a layer are the floor is laid. Some form of solid insulation board is used, the thickness of which depends greatly of the floor thickness.

Fitting solid floor insulation

Fitting solid floor insulation usually involves major works. The floor level generally needs to be maintained resulting in the need to break up and remove the current floor before replacing it with a new one. This will involve obtaining Building Control approval and you never know exactly what you might find under the floor which could complicate the project. We would only normally suggest actually implementing this recommendation if the floors concerned were being replaced for some other reason.
