⚠️ IMPORTANT UPDATE ⚠️

Due to the ongoing situation in the Middle East, we are currently seeing price increases and supply shortages across a range of building materials.

This is impacting manufacturing, transport, and availability worldwide — and unfortunately, it’s something affecting the entire industry.

At GNK Builders Merchants (est. 1983), we are doing everything we can to:
🔹 Keep prices as competitive as possible
🔹 Maintain strong stock levels
🔹 Support our customers through these changes

However, we do advise all customers to:
👉 Plan ahead where possible
👉 Order early to avoid delays

We appreciate your understanding and continued support 🤝
