What is the DGCOS?

At T&K Home Improvements, we are committed to delivering excellence in every project we undertake, from windows and doors to conservatories and roofline solutions. Part of that commitment means partnering with organisations that share our dedication to quality, transparency and customer satisfaction.

That’s why we’re proud to work with the Double Glazing & Conservatory Ombudsman Scheme (DGCOS) across all of our home improvement services.

Why It Matters

DGCOS plays an important role in the UK glazing industry by providing clear consumer protection for homeowners investing in double glazing, conservatories and related products. Established with the aim of boosting consumer confidence and raising standards across the sector, DGCOS works independently to give homeowners reassurance when they choose a reputable installer – something every T&K Home Improvements customer benefits from.

The scheme is widely recognised for its rigorous accreditation process, meaning each member has demonstrated a commitment to ethical trading and high-quality workmanship. When you work with T&K Home Improvements, our DGCOS membership demonstrates that we meet these exacting criteria and adhere to industry standards that matter to you.

How They Support You

One of the main ways DGCOS supports homeowners is through financial protection and dispute resolution services. If you enter into a contract with a DGCOS-accredited installer and register your project with the scheme, you can benefit from deposit and stage-payment protection insurance that helps safeguard part of the cost you have paid in advance. There is also access to insurance-backed guarantees that offer further peace of mind long after installation.

In the event that something doesn’t go as planned, DGCOS offers an alternative dispute resolution process and access to an independent ombudsman, helping to resolve issues constructively without the need for formal legal action. Having this added reassurance can make a significant difference to the overall experience of improving your home.

T&K and the DGCOS

As a T&K Home Improvements customer, our partnership with DGCOS means you can feel confident that your home improvement project is backed by a recognised consumer protection scheme with a track record of supporting homeowners. It reflects our belief in transparency, fairness and industry best practice, and reinforces our promise to offer products and services that meet high standards of quality and reliability.

Choosing T&K Home Improvements with DGCOS accreditation means choosing peace of mind, because we not only deliver excellent workmanship but also stand behind that work with additional protection and support for you.
