Not every project follows standard sizing. Tight riser spaces, legacy meter positions, unusual layouts, and multi-meter configurations create challenges that generic products cannot solve. A poor fit risks compliance, delays the programme, and creates costly rework. Our bespoke meter overboxes are designed and manufactured to your exact measurements, with optional fire ratings, custom finishes, and the same fast lead times as standard products. Every bespoke overbox is manufactured at our Nuneaton facility under ISO quality controls.
