When you invest in your property – whether it’s new windows, doors or a home extension – you expect quality workmanship and the long-term peace of mind that the work is guaranteed.

However, many homeowners may not realise that not all guarantees are protected should something go wrong.
An insurance backed guarantee (IBG) indicates that your installation is supported by an independent insurance policy.
This means that, should the original installer cease trading and be unable to honour the terms of their written guarantee, you will still be able to make a claim under the terms of the original guarantee.
Without this vital protection, your guarantee is vulnerable to changing circumstances.

There can be many reasons why a company ceases trading – the economic climate, supply chain issues, staffing problems and personal circumstances can all be contributing factors.
Without an IBG, if a company ceases trading, the guarantee they provided you with becomes meaningless.
An IBG protects you in several ways:
An IBG usually corresponds to the terms of your installer’s original written guarantee. Often covering:
However, it doesn’t extend to aspects outside the installer’s control such as general wear and tear, accidental damage, misuse or external factors such as flooding or structural movement.
It’s also worth noting that an IBG doesn’t replace any manufacturer warranties on the products themselves. Instead, it sits alongside them, adding an additional layer of protection.
In the UK, FENSA-registered installers such as Window Wise must self-certify that replacement window and door installations comply with building regulations. FENSA notifies the local council on behalf of the installer, then the homeowner receives a FENSA certificate for their home improvements.
This process should then trigger the issuing of an insurance backed guarantee. This is a crucial aspect that homeowners should be aware of.
In addition to the comprehensive ten-year guarantee issued to you directly from Window Wise, you will also be sent an insurance backed guarantee relating to the home improvement work completed at your property. This will be instigated by our self-certification with FENSA.
Our insurance backed guarantee is underwritten by Hadron UK Insurance Co. Ltd . If you move home, the IBG is transferred to the new homeowner along with your FENSA certificate.
It is very important to keep these documents safe.
A case reported by The Guardian highlights how important it is to understand exactly what protection is in place for your home improvements.
A homeowner who had spent £6,000 on new windows experienced damp issues and repair costs after the installer went out of business.
Unfortunately, the installation hadn’t been registered with FENSA or linked to an insurance provider, which meant there was no IBG to fall back on.
As a result, they were left with a costly and complex situation.
An insurance backed guarantee is a critical safeguard that will protect you for the long term.
Understanding the importance of IBGs before you plan your home improvements helps you choose the best installer for your work – and gives you much needed peace of mind.
