Guarantee Terms and Conditions

Scope of Guarantee

The guarantee is available only for the provision of wet plastering on private residential premises in the UK which is carried out by an approved British Gypsum Certified Plasterer using products from the Thistle brand portfolio, which include: Thistle HardWall, Thistle ToughCoat, Thistle BondingCoat, Thistle Universal OneCoat, Thistle MultiFinish, Thistle BoardFinish, Thistle SprayFinish, ThistlePro DuraFinish, ThistlePro PureFinish, ThistlePro UniFinish, Thistle GypPrime, Thistle Bond-it, ThistlePro Magnetic and Thistle DriCoat. All works are to be installed in accordance with the British Gypsum guidelines as detailed in the ‘British Gypsum Site Book’.

Please refer to for the full Site Book. This guarantee does not affect a homeowner’s statutory rights.

The guarantee will still cover the application of complementary products but strictly excludes use of competitors’ products when the product is available from the Thistle brand portfolio. Please note: use of competitors’ products will invalidate your guarantee.

Complementary products: the application and use of these products are covered by the workmanship guarantee; however, in the case of product failure, your plasterer would claim directly from his supplier and/or the manufacturer to cover costs for any remedial work required. Your statutory rights remain unaffected.

If the Scheme member defaults on their guarantee British Gypsum will ensure they complete the work to a satisfactory level. If this is not possible British Gypsum will make alternative arrangements by appointing another Scheme member within the liability of the guarantee to complete the work.

Claims under Guarantee

Before making a claim under the guarantee the homeowner must first try to resolve the matter with the British Gypsum Certified Plasterer Scheme member. Only where the matter has not been resolved to the homeowner’s satisfaction should they contact the British Gypsum Certified Plasterer Membership Scheme office.

Limit of liability

The guarantee covers the amount by which the cost of remedying the defective work, when taken together with the cost of the work already done, exceeds the original price quoted for the work. Subject to this, the homeowner remains liable to pay the British Gypsum Certified Plasterer Scheme member for the work carried out by the British Gypsum Certified Plasterer Scheme member unless otherwise agreed.

Where the complaint refers to property or personal damage, British Gypsum will in the first instance ask the homeowner and their Scheme member to pursue this through the Scheme member’s liability insurance. However, if for any reason this is not possible, British Gypsum will ask the homeowner to pursue theclaim under their household insurance policy.

Under these circumstances British Gypsum will cover any excess payable and any additional cost the homeowner suffers due to an increase in their household insurance premium in the following twelve months. However, British Gypsum will not pay for any losses or costs that are not directly covered by the Terms and Conditions of this guarantee.

The liability to British Gypsum under the guarantee is capped at twice the invoiced cost of the work and does not cover consequential loss. This will not affect consumer statutory rights.
