Thanks, i know how to deal with court claims etc etc, but i wanting to form a technical defence, based soley on the failure to send a letter before claim (if possible)

Court claim received from water company I have not received a letter before claim from the water company or detailed particulars. I have dealt with a fair claims in my time and on this case i want to build a defence "soley" on the basis that no LBCC has been received. I realise the level of success that this may achieve..... Please can someone help me with some wording for this (i dont really wish to go into details of the claim ) just really basing the defence on what i have mentioned...
