As part of the comprehensive protection offered by DGCOS, every customer of an accredited member will receive deposit and stage payment protection and an Insurance Backed Guarantee. Accredited members are required to register your details on the DGCOS online system within 48 hours of you signing the contract. DGCOS will then issue your insurance certificate, which we recommend you keep with your contract. Once the installation is complete, the Insurance Backed Guarantee will be issued along with a customer satisfaction survey to complete and return in the prepaid envelope provided.

Deposit and Stage payment protection

It is normal practice for installation companies to request a deposit and/or stage payment to safeguard them should the customer cancel the order. But what happens to the money you have paid if your installer has ceased to trade? Our deposit and stage payment policy protects any monies you pay up to 25% of the contract value, with a maximum limit of £50,000.

The policy will last for 120 days from the date the deposit is paid, however, for larger projects, this may be extended upon request.

If you need to make a claim on your policy you can do so by contacting DGCOS, or the insurer directly, and requesting a claims form. The insurer will either arrange for the completion of the contract, at no further cost to you, or will refund your deposit as detailed on your policy certificate.

Insurance backed guarantee

Our Insurance Backed Guarantee lasts for a maximum 10 years and protects the guarantee you receive from the member upon completion of the installation.

Should your installer cease to trade and you require some remedial works within the duration of your guarantee, you can make a claim on your insurance policy. To make a claim you will need to contact DGCOS, or the insurer directly, and request a claims form. Providing the remedial works are covered by the original guarantee, as issued by the member, the insurer will arrange for the repairs to take place free of charge.


In addition to our comprehensive insurance policies, DGCOS also has access to a unique Compensation Fund. The primary function of this fund is to honour any awards made by the Ombudsman, and any monies drawn from the fund must be done so only with the Ombudsman’s authorisation.
