Hiring a tradesman to install cavity wall insulation
For a home to be properly energy efficient it will require wall insulation. Around one third of heat loss in an average home occurs through the walls. As a result you could end up wasting money to keep your house heated, which will also increase your environmental footprint. By installing wall insulation you can save yourself a great deal on your energy bills, until the installation job has paid for itself!

What do I need to know about installing cavity wall insulation?
If you are thinking about cavity wall insulation, the first thing you will need to check is the state of your walls. Most homes built after the 1920s have cavity walls: two walls with a ‘cavity’ in between. Houses older than this are more likely to have solid walls, which require different types of insulation. If your home was built after 1990, you may find that your walls already have insulation. If you are not sure, you can hire a specialist to perform a ‘boroscope inspection’; this is when a small hole is drilled in an external wall to see if the cavities inside are hollow. They will then fill in the hole so that you can barely notice the work. Alternatively, you could speak to your local authority’s building control department, who will likely have records on your property.
Cavity wall insulation is always installed through an external wall. The Pro will drill into the wall and then blow the insulation in using a pressurised hose. Because specialist equipment is required, this is not a job for a DIY enthusiast. Your hire will need access to all of your external walls, so plan accordingly beforehand. With proper access, a Pro could finish in as little as two hours! If you share an external wall with a neighbour, a specialist can install a cavity barrier so that the neighbour’s home is not affected. Alternatively, you might want to ask your neighbour if they want to see if the two of you can get a discounted deal to install insulation in both properties.
It is important to make sure that your job is done to proper standards. Usually an insulation specialist will have either learned their trade on the job or completed an apprenticeship scheme. Always ask about qualifications, as well as customer reviews; an established professional should have plenty of positive reviews to show you. It is a good sign of a specialist’s quality if they belong to a national tradesmans’ organisation, such as the Thermal Insulation Contractors Association (TICA). These groups have high entry standards for quality and professionalism that members must constantly meet. Make sure you are confident in your final hire: as well as doing the job itself, they will have to choose the best type of insulation to suit your situation, so knowledge is key. Your final hire should have active Public Liability Insurance, as well as a guarantee for their work.
The cost of hiring a tradesmen to install cavity wall insulation will depend on the size, type and age of your property. If your walls are old and are not in a good condition, repair work may be necessary first. The same goes for if your property contains damp or asbestos, which would need to be removed before the new insulation could be installed. Most of the time, a professional will offer a free assessment of your property to give you a bespoke quote, so take advantage of this if you can. Depending on your property, the cost of installing cavity wall insulation could be anything from £300 to £750, though this will also vary based on where you live in the UK. Remember though that more insulation means reduced energy bills. Within a few years the installation will likely pay for itself.
