How Much Does Spray Foam Insulation Cost?

The cost to insulate with spray foam can vary widely, from a few thousand pounds to over £7,711 for a whole house. Spray foam insulation is an effective option for filling gaps and crevices that traditional sheet insulation may miss, potentially increasing energy savings and reducing monthly bills. However, it requires more time and manual labor to install, which can influence the overall cost.

There are several variables that play a role in determining the exact price, including the type of spray foam used:

  • Open cell insulation
  • Closed cell insulation

Open cell insulation is less expensive and often preferred for residential projects due to its effectiveness and lower cost. Closed cell insulation, while offering certain advantages, is more commonly used in commercial settings. The cost for open cell density might be around £0.34 per board foot, whereas closed cell insulation might start at around £0.54 per board foot.

For a 93 sqm area (equivalent to approximately 1000 sq ft), the cost of spray foam insulation can range from as low as £1,002 to as high as £2,775, with the average UK homeowner spending around £1,927.

For the best results, we recommend that you get in touch with spray foam insulation contractors in your area to compare quotes. This is the only way to ensure you get the best deal possible and maximize your savings at the same time.

Labor Costs

Insulation is something you might be able to do on your own, but certified professionals will be able to maximize your insulation and savings for the job. You are likely to use 10-15% more of the spray if you do it yourself, so finding out the board footage amount and adding it up from there will give you a clearer picture of what you stand to lose on spray costs if you actually tackle the job on your own.

Amount of Space

Naturally, this is the biggest aspect at play. Are you going to spray the entire house or are you just looking to finish an attic?

Spraying the whole house may seem like the expensive option, yet the return on investment is what makes it so attractive. If you are renovating the home and have access to side walls, spray foam is a fantastic way to go.

  • Just remember, every foot of board space you need to insulate can add anywhere from £0.34 cents to over £0.77. This means if you have a 10-foot wall that is eight feet high, you might spend anywhere from £26 to £61 just to insulate that small portion.
  • If you think about how much surface area you have touching exterior walls, it is going to increase a large amount.

    Spray foam insulation offers you a fantastic way to boost your home value and reduce energy consumption each and every month. If you are in need of some professional assistance, it is always recommended that you compare quotes from several contractors before you agree to have any work done. Comparing quotes will give you a fair representation of pricing trends in your area.
