External Meter Overboxes

Weatherproof Protection. Built for the Outdoors.

When utilities are exposed to the elements, the right enclosure becomes critical. Our external meter overboxes are built from zintec steel with a durable powder coated finish to protect gas, electric, and water meters from rain, wind, impact, and tampering. Powder coated to any RAL colour. Manufactured in the UK and delivered in days, not weeks.

External utilities face constant exposure to rain, wind, UV, vandalism, and accidental damage. If the enclosure fails, the meter is exposed, the service is at risk, and compliance can be compromised. A poor-quality meter box cover leads to failed inspections and higher maintenance call-outs. Our external meter overboxes — available as a gas meter box cover or electric meter box cover — are purpose-built for outdoor environments, securing utility points, extending product life, and keeping your building ready for sign-off.
