Re-costing
Thank you for your email, in terms of the costing we are more than happy to work with you to bring this down. The switching can be converted to conventional to remove the cost of the Rako system and revise the circuitry to what we think would work best for you. In regards to fittings, the schedule we put forward are proposed fittings, we can look at alternatives to bring the cost down or leave the supply to yourselves.
Just let me know your thoughts on this and if you would like us to work further on the design, for us it's a process to ensure you are happy with all elements of the design.
