Thankyou for all your replies.
Hager do one that will fit in their distribution board but it is over £430.00+vat.
I found this at CEF - 3 Phase Multifunction Energy Meter MID Certified with Pulse and Modbus - https://www.cef.co.uk/catalogue/products/5031071-three-phase-multifunction-energy-meter-mid-certified-with-pulse-and-modbus for £135.00+vat.
I'll check the depth available in the board to see if it will fit.
