UPDATE:

Email received from installing contractor last week 21st March saying he was going to speak to LG and ring me back on the 23rd with update.

Still nothing from him but have heard from Graham Hendra via email on Thurs 26th who advised the following:

Today I spoke with the installing contractor

He will be in contact about your machine together some resolution will be found

regards

Graham Hendra
General Manager Airconditioning LGEUK

Still waiting to hear from the installer yet though.
