Underfloor Insulation Cost

The cost of installing insulation under your floor can vary significantly depending on the size of your home, the type of floor you have, and various other criteria.

On average, insulation for suspended timber floors will cost around £4700 for most standard-sized homes, while solid floor insulation can cost significantly more.

Most homes will have a suspended timber floor, but in some rare cases, you might need to install insulation for a solid concrete floor. This is a much larger project, and solid floor insulation takes a long time and a lot of work to install, so costs are higher.

However, there are some government grants available in the UK that may reduce these costs. Check out the Energy Saving Trust for information and advice on potential grants and schemes you may be able to take advantage of if you want to insulate floorboards and do not have a huge budget available.

Underfloor Insulation Benefits

There are many benefits to under floor insulation, particularly for suspended floors. Let’s take a look at some of the most significant benefits of insulating your floor properly.

Most importantly, as energy costs continue to skyrocket, a well-insulated floor will reduce heat loss, making it cheaper and easier to keep your home comfortably heated. This can make a big difference to the size of your energy and heating bills and will save a significant amount of money in the long term.

An uninsulated floor can feel very cold. Insulating the floor can make it feel warmer, keeping your home more comfortable during the cold winter months. Your comfort is important, and the difference that insulating your floors can make can be very significant.

Poor insulation can lead to damp rising up from the floor and through the walls. This leads to warped skirting boards, and if it reaches the electrical sockets, it can be extremely dangerous. Good insulating materials will keep you safe and prevent your floor boards from rotting.

Frequently Asked Questions

What is the best insulation for underfloor?

Different types of floors require different insulation types. A solid floor will require rigid insulation to be installed under it, but an upper floor or suspended timber floor with wooden joists will need foam materials for insulation or wool to fill the void rather than rigid insulation.

If you are unsure about your floors and about foam materials vs rigid insulation types, get in touch with our team today, and we will help you to pick the right insulating materials for your home’s specific needs.

Is underfloor insulation a good idea?

Underfloor insulation allows you to keep more heat in your home rather than letting it escape into unheated spaces through the floor.

It might not be as significant as loft insulation, but insulating any crawl space or other void below floor level can make a huge difference to the warmth and comfort of your home, as well as to the amount of money you find yourself spending on heating your home every winter.

Insulation under the floor of your home is generally a very good idea. It can be expensive to initially install, but once it is set up, it will pay for itself in only a few years.

Even better, there are a number of schemes and grants available to make insulating basement space underneath your wooden floors more affordable than you might expect.

What is the best insulation for under the house?

There are several different types of insulation available for installation under your house, all of which have certain advantages and disadvantages. Any insulation material under your floor will keep your home warmer than an unheated cellar would, though!

To choose the right insulation materials to put under your floor boards or in your basement space, get in touch with our team. One of our experts will be able to discuss your situation and needs and recommend the ideal materials for the space underneath your floor.

We can provide a tailored solution, ensuring that it meets your unique needs perfectly every time.

What is the minimum floor insulation UK?

According to the Energy Saving Trust, when installing a new floor in England or Wales, the floor should achieve a U-value of 0.25 W/m2K or less, if possible, and to achieve this standard, you will typically need at least 70mm of high-performance insulation foam, though this will vary depending on floor type, shape, and size.

This is for a suspended floor: solid floors are insulated differently from suspended floors. Rigid boards of foam are applied beneath the concrete floor surface, with a damp-proof membrane used to protect the concrete and prevent the floorboards rotting.

Similarly, external walls should have a damp-proof course of bricks at the base. This, combined with the vapour barrier and breather membrane, will prevent damp from rising up into the walls and warping your skirting boards.

How thick should underfloor insulation be?

The thickness of the material required to insulate your floor varies depending on which materials you are using for your insulation. If you are using a high-performance material like rigid foam boards or other foam materials, a 70mm thickness will be sufficient.

If you are using more affordable materials such as mineral wool or sheep’s wool, you will need at least 150mm of insulating material under your suspended wooden floor in order to protect your home enough to make it worthwhile, meet regulations, and save a meaningful amount on your energy bill.

Do you need building regs for under floor insulation?

If you are adding insulation to your flooring, the work must be done in accordance with local construction codes. Although your installer will usually take care of this for you, it is your obligation to follow all regulations.

If you reside in England or Wales, the floor should ideally have a U-value of 0.25 W/m2K or less. The U-value measures how rapidly heat moves through the floor. To meet this criterion, you will need at least 70mm of high-performance foam insulation or 150mm of mineral wool, although this can vary depending on the construction, shape, and size of your floor.

If you are replacing at least half of a floor, whether or not this was part of your original plans, you must insulate to these requirements.

Before beginning work, it is advisable to contact your local Building Control Office or Building Standards Department for more information on building regulations and for the specific requirements in Northern Ireland and Scotland.
