JMLHardware Ltd made to perfection a bespoke 60 minute warrington-fire-tested-and-approved electric meters overbox for the entrance hallway (escape route) of a small residential building of 3 flats, approved by RBKC Council, London. They were good to deal with and communication was seamless overall. Highly recommended!

I wasted 4weeks awaiting a reply from Meterbox ,I contacted JML and got an answer to my question in 10 minutes…..after discussing my options I placed an order and received the box in 48 hours. It is well designed and superbly constructed in aluminium with a grey finish ..This Company really is customer focused with an emphasis on good communications at all price points.
