How much does external solid wall insulation cost?

Before the commencement of any project, it’s always best to get an estimation of the cost. However, determining the cost of an external solid wall insulation is not the easiest of tasks as it relies on varying components such as the insulation materials to be used, labour cost and installation as well as the type of decorative finish to be incorporated. And depending on your choice of insulation material, some may need some adhesives while others may require some fixings which also contributes to the differences in price. As a result, the determination of the material cost alone can be tricky and even more so when various materials cover varying areas.

With that in mind, the cost of external solid wall insulation generally ranges between £80 to £100 per square metre2. As a result, a small flat can cost from £6000 to £9000 whereas a large detached house can have a price ranging between £21000 to £23000. To earn back your investment in terms of energy bill savings can take a couple of years, but it’s surely worth the try as there are several other benefits associated with installing an external solid wall insulation system. What’s more? Another huge factor that can influence the cost of your system is also the amount of work that’s required, how easy it is to be accessed by the installers and lots more

If you’re looking to cut down on the cost of your external solid wall insulation, then the best time for an installation might just be when you’re having another decorating or building project done such as fitting a new roof, window painting, installation of solar PV panels and more. This way, you’ll be able to spread the cost and have a greater value for each penny expended.

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external wall insulation.
