Do I Need Cavity Wall Extraction?

Although the primary purpose of cavity wall extraction is to make houses warmer, this doesn’t mean that it doesn’t come with its drawbacks.

It goes without saying that we want our homes to be as comfortable as possible, so when something starts to go wrong – we should act quickly to get it rectified as soon as possible. Essentially, cavity wall extraction involves the process of removing insulation from the cavity space by using specialist equipment.

Why Remove Cavity Wall Insulation?

When it comes to cavity wall insulation, the number of benefits it affords are somewhat endless. Not only is it one of the cheapest and most effective ways to reduce your energy usage and drive down your utility bills, but it also keeps your home warm. However, this doesn’t mean that cavity wall insulation hasn’t come with its own problems. Here are just some of the reasons why people choose to have their cavity wall extracted:


If cavity wall insulation has been installed into a property that should not have the cavities filled or the work was not carried out in the correct manner, then dampness can be the first sign that there’s an issue. Cavity walls can be insulated incorrectly if they’ve not been filled correctly – they might be over-packed, underfilled or even whole areas might be missed. The role of the cavity is to actually keep water and moisture away from the inner walls of a property. In the event of this happening, it’s best to enlist the help of a professional team. If you try to do anything yourself, then the problem might just end up being exacerbated.


One of the main reasons as to why people decide to have their cavity wall insulation removed is because their property isn’t suitable for it. For instance, if your property is often subject to wind-driven rain, then it is not recommended that a cavity wall is in place. Rainwater has the potential to penetrate through weak spots when blown onto the surface of the external walls. Once the damp and moisture seeps through the outside surface of the wall, it then starts to make its way through the insulative material and into the integral part of the wall. Damp spots are then likely to occur, which will then result in mould.

If you have an older home that has damaged or faulty brickwork, then it’s likely that there might be a penetrative damp problem. If the cavity is filled with insulative material, then there is the potential for the material to become moist. It is therefore important that you check your property to see whether there are these underlying issues.

Utility Bills

Although insulation can make your house warmer by trapping the heat and putting less demand on your heating systems, cavity wall insulation that isn’t working at peak condition can actually have an adverse effect on utility bills. If you notice that your bills are starting to rise, then this could be a good indication that the insulation isn’t doing the job properly.

It must be noted that these problems can sometimes take a long time to actually become noticeable, therefore it’s advisable that you try to counteract any problems at the very first opportunity. At UK Energy Management (NE) Ltd, our cavity wall removal services are on hand to remove any issues you may have with cavity wall insulation. It can be challenging to spot structural issues and installation problems, that’s why it’s best to enlist the help of professionals that have a wealth of experience and knowledge behind their belts.

Benefits of Cavity Insulation Removal

Now that we have addressed exactly why people have their cavity walls removed, it is also important to understand the benefits of having cavity insulation removal. Here are just some of the reasons:

Warmer House – When the cavity wall insulation becomes wet, this means that your house will be a lot colder. The heat won’t be trapped inside, but it will be able to easily leave. Nobody wants to live in a cold home, so having the cavity wall removed means that the heat will be trapped inside.

Reduce Utility Bills – It is a known fact that insulation can help to keep your utility bills down by trapping the heat inside. However, as soon as there are issues with your insulation then there’s a high chance that your bills will start to rise again. This is because the heat will be able to easily escape, which in turn means that your heating systems will need to work much harder to actually heat your home. Having your cavity insulation removed will ensure that the problems are fixed and addressed so that the heating systems don’t have to work so hard.

Reduce Damp – As noted previously, damp and mould can be present when cavity wall insulation becomes wet or damaged. This can actually pose significant health risks such as asthma, so it’s vital that this is picked up on.

Cavity Wall Extraction and Government Funding

As aforementioned, having cavity wall extraction can significantly improve your living conditions. The last thing you want is to live in a house which has damp or mould. Not only that, but having poor insulation means that your utility bills have the potential to rise. This is a problem especially for those who come from low-income households because insulation can have a significant impact on your bills. Cavity wall extraction can be quite a big task that can be expensive if funded yourself. However, did you know that there is a cavity wall extraction grant that you could be eligible for? This grant allows these households to have their cavity wall sorted, free of charge. These grants are all a part of the government’s Energy Company Obligations scheme, which is designed to cover the cost of home efficiency improvements for those who live in low-income households or with vulnerable individuals.

This grant does not apply to absolutely everyone though. You must be eligible for the grant by falling under certain conditions. The grant can be claimed by anyone who receives the following benefits:

● Child benefits

● Carer’s Allowance

● Job Seeker Allowance

● Disability Living Allowance

● War Pensions Mobility Supplement

It is important to consider that these are not all of the conditions, and you might still be eligible for the grant. To find out if you qualify for the grant, then fill in UK Energy Management (NE) Ltd’s form. It is our goal to make your home a more comfortable place to live in, and a cavity wall extraction could be just the thing you need to achieve that!
