You may not consider your work to be particularly risky, but the truth is, accidents can happen at any time. That’s why it can be a good idea to purchase cavity wall insulation installer insurance.
With over 25 years’ worth of experience, we are perfectly placed to find the ideal insurance cover for your business. You can trust us to provide a policy that will offer financial protection for you, even in times of trouble.
In short, cavity wall insulation insurance is designed to provide financial protection for you and your business. At Markel, we can help you find a policy that ticks all the right boxes when it comes to ensuring you’re suitably covered should the worst happen.
We can create a bespoke insurance policy for you that meets all of your business' requirements. In turn, you’ll have added peace of mind that you’ll remain financially comfortable even if something goes wrong.
Even if you’re extremely skilled at what you do as a cavity wall installer, and you have years of experience, you never know what might happen next. The smallest mistake could end up costing you big. That’s why it’s a good idea to have suitable cover in place.
For instance, imagine you are carrying out a cavity installation at a customer’s home. As part of the job, you need to drill holes in the walls. However, you accidentally drill through a pipe in the process which causes significant water damage. The customer then takes action against you, making a claim for property damage and in turn, expects you to pay the cost of compensation and legal fees. With insurance in place, you needn’t worry about having to pay for these costs out of your own pocket. Instead, you can trust that your policy will cover this, saving you from financial fallout and allowing you to continue business as normal.
You can also choose to have employers’ liability insurance included in your policy. This is a must if you have anyone working on behalf of your cavity wall installation company. In fact, employers’ liability cover is a legal requirement, and you must have a policy with a minimum value of £5 million. This type of insurance provides financial cover if one of your employees decide to make a claim against your business if they become unwell or injured while carrying out their job.

Public liability insurance covers you for claims made against your cavity wall insulation installation company by members of the public who may experience an injury or damage to their property because of your business, including your customers. We offer public liability insurance from £1 million to £5 million.
Example of a claim:
While installing insulation at a commercial property, you accidentally scratch a parked car as you walk from your van to the building while carrying your foam gun. The owner of the vehicle takes legal action, making a claim against your business for property damage and expects you to pay for the repair of the damage caused.
If you have employees working on behalf of your cavity wall insulation company, by law, you need to have employers’ liability insurance in place with a value of £5 million as a minimum. This protects your business if one of your employees sustains an injury or becomes unwell while carrying out their job.
Example of a claim:
An employee slips and falls while working from a height when the rung of the ladder they are standing on becomes loose. They sustain severe injuries, meaning they are unable to work while they recover from the incident. Your employee processes a claim against you for their injuries and loss of earnings due to not being able to continue working.
Tools insurance offers financial cover in the event you need to replace your equipment. You will be covered if a flood, fire or theft means your tools go missing or become damaged. We offer portable equipment insurance from £1,000 to £5,000 per person.
Example of a claim:
The building where you securely store your expensive tools is broken into. You use your tools insurance to claim for the replacement cost of your missing equipment.
Legal expenses insurance can help to cover the cost of defending or pursuing legal actions against other parties such as suppliers, clients or employees. This could be for contract disputes, tax enquiries (including IR35), attending jury service, debt recovery, personal injury, as well as any award you are required to pay following an employment dispute with an employee. There is a limit of £100,000.
Example of a claim:
A supplier has failed to deliver building materials you’ve paid for and is ignoring your requests for a refund. You face the costs associated with recovering the debt owed to you.
If you are unable to work as a result of an injury you have sustained from carrying out your job, or while you are travelling to or from work, occupational personal accident insurance has you covered. Depending on your injuries, you may receive a single lump sum or weekly payments.
Cover the equipment and machinery you use as part of your cavity wall insulation business with owned plant insurance. This provides financial protection should anything be stolen or becomes damaged with cover ranging from £10,000 to £50,000.
If you rent equipment from a hire company but it goes missing due to theft or it becomes damaged, hired in plant insurance will cover you. Our policies range in value between £10,000 and £50,000.
Should you need to revise any of the cavity wall insulation work you’ve carried out due to an event such as fire, flood, theft or malicious damages, contract works insurance can cover the costs involved.
To be protected in the event your materials are lost or damaged while being transported from one location to another, goods in transit insurance is a must. This type of policy covers goods that are being moved by a courier or even in your own work vehicle.
If you provide designs or advice as part of your business model, it’s a good idea to have professional indemnity insurance in place. This type of insurance handles any compensation costs or legal fees that may come your way if a client takes legal action against you for an error in the services you have provided.
At Markel, we appreciate that when it comes to insurance, a one-size-fits-all approach just won’t cut it. After all, your business is unique, and your insurance needs will be too. How much your cavity wall installer insurance will cost will depend on a variety of factors, such as the size of your business, the type of equipment and material you use, and if you work alone or if you have any employees.
Our policies start from £10 a month and we can tailor your cover to ensure it meets both your insurance needs and budget.
These frequently asked questions are designed to help you and include questions relating to policy cover, pricing and ‘technical’ terms.
Ideally, you should have suitable cavity wall installer insurance in place before you carry out any work for your customers. This will make sure that you are covered from the get-go.
While public liability insurance is not a legal requirement for a cavity wall insulation installer, it can play a huge part in the success of your business. If a member of the public was to become harmed in any way as a result of your business, this type of insurance will take care of the associated costs while you continue to run your company as usual.
Yes, it’s recommended that you have insurance in place even if you are self-employed and do not have anyone working on your behalf. You never know what might happen, so it’s a good idea to be prepared in case something goes wrong.
