Who Are Guarantee Protection Insurance Ltd?

As an add-on to our 10-year basement and cellar repair guarantee, we are able to offer our customers the added benefit of a Guarantee Protection Insurance Ltd policy.

Endorsed by Trustmark, Guarantee Protection Insurance Ltd (GPI) is a UK based general insurer authorised & regulated by the Financial Services Authority. As a highly respected operator within the UK insurance market, with over 25-year experience, they specialise in working with government recognised trade bodies such as the Property Care Association (PCA). This means that contractors need to display sufficient experience and qualifications, high standards of workmanship and customer satisfaction to offer GPI coverage

What does Guaranteed Protection Insurance cover?

For a modest one off premium payment (i.e. no annual premiums), that can be incorporated within the cost of the basement and cellar repair, Guarantee Protection Insurance Ltd will provide cover, for up to 10 years, for a structural waterproofing repair originally covered by our basement and cellar guarantee. 

The benefits of Guaranteed Protection Insurance

Put simply, it means consumers are protected if Wise Basement Systems was ever in the unlikely position of ceasing trading. It means no substantial costs in the future and offers the peace of mind that comes with knowing your basement or cellar repair will always be covered by a fully qualified and experienced PCA recognised structural waterproofing specialist.
