Why GMS Are the Trusted Choice for Block Management Companies

When it comes to water hygiene, commercial plumbing, and unvented hot water servicing, block management companies need a partner who not only understands compliance but also delivers practical, long-lasting solutions. At GMS, we’ve built a reputation for excellence by combining decades of industry experience, a proven commissioning background, and long-term trusted relationships with property managers across the UK.

Experience That Goes Beyond Maintenance

We don’t just service systems — we commission them from day one. This means we understand exactly how water systems are designed to perform and how to keep them compliant, safe, and efficient over the long term.

Our expertise covers every aspect of water hygiene and plumbing in managed residential blocks, including:

• Legionella control and compliance – keeping residents safe and supporting managers with clear, audit-ready reporting.
• Commercial plumbing services – from preventative maintenance to rapid response call-outs.
• Unvented hot water servicing – ensuring safe, efficient operation in line with legal requirements.
• Cold water storage tank repairs and replacements – extending the life of ageing systems or delivering full upgrades when needed.

This broad capability allows block management companies to trust us with both day-to-day servicing and complex system overhauls.
