The Double Glazing & Conservatory Ombudsman Scheme aims to protect consumers and improve the reputation of the glazing industry. Find out more about DGCOS by selecting the relevant page on the right. Most properties lose heat through their windows, but energy efficient glazing keeps them warmer and quieter.

Energy efficient windows can also make your home more comfortable and reduce your carbon footprint. Conservatories are a great way to add style and value to your home. They are available in a huge range of bespoke, classic and contemporary designs that can help open up your property and allow more light to enter.

Roofline products are designed to protect your home from the elements that can lead to damp and mould on the inside of your home. Replacing your roofline with a modern uPVC alternative will prevent rotting, discolouration and improve the performance of your roof. Other products covered under the DGCOS scheme include garden rooms, garage doors and porches.

After 2 years of back and forth between the DGCOS, their member company and the Ombudsman I've been left with an unfinished extension which according to the independent inspection carried out by the DGCOS has poor workmanship and requires remedial works to put right, no financial or insurance back guarantee and no other avenue except through the courts as the member company has already breached the Ombudsman ruling by not carrying out agreed works.
All I have had is an apology for the way my case has been handled and that they will learn from this and no other customer will have my experience

This Ombudsman Service is quite honestly a life saver!! An 100% amazing and free (yes free!! ) mediation service which is most definitely an essential requirement for everyday consumers, when thinking of purchasing Double Glazing/Conservatories. Please make sure your supplier is a member with the DGCOS, please!! When many others let us down, this Service did not. They are to the point, factual and steadfast where fair, unbiased consumer advice is required and this mediation resolution service is executed in a controlled, concise, efficient and highly effective manner, outstanding is an understatement

This service was outstanding and an absolute godsend for us. We were dealt with professionally and, as you would expect, impartially but with a good level of sympathy given our circumstances. DGCOS put in a lot of effort to helping us out and provided good levels of communication and explanation throughout the process. Myself and my husband were very impressed with the service and words cannot express how grateful we were that it was available to us, all free of charge too. 10 out of 10.

Having reached a point of impasse in endeavouring to resolve issues of poor workmanship and a leaking roof, we decided to utilise the services of DGCOS as a last resort before legal action. Fortunately, this decision proved to be the right one and we would like to thank Tracy for her intervention and resolving what could have been a long and expensive drawn out process. The matter was subsequently concluded to the satisfaction of all concerned and I would not hesitate in recommending this organisation.

It's been a pleasure dealing with DGCOS. Tracy Dilworth took up our case and she was extremely efficient and thorough. She put in a lot of effort researching all the necessary background issues and supported us fully when representing us to the company we were in dispute with. Tracy kept us informed all the way about the progress she was making with a cheerful, no nonsense manner. An excellent service, Tracy. We're really impressed and grateful to you. Thank you.

We have been members of the DGCOS for over 7 years. We feel it offers both our customers and us reassurance that if any problems were to arise they would be dealt with fairly and impartially. We were vetted prior to being excepted as members and are regularly monitored to ensure we are still operating under their guidelines, this ensures that they are only supporting genuine, well run companies. Although using the registration website is easy to use and navigate, they are always happy to help when we have contacted them for help or advise.

DGCOS performed an invaluable service to us in solving a dispute between us and our installers over a conservatory extension build. It had reached an impasse and without the help of DGCOS I dread to think of where we would be even today. We cannot thank Charlotte and her colleagues enough for their intervention and coming to a solution with which we were entirely satisfied. Thank you so much.

Being covered by dgcos was invaluable. When a disagreement arose it was easy to register the issue and I felt very supported. Thankfully an agreement was facilitated without further escalation. Very grateful indeed and all credit to its competent staff team.
