I went through the Which process once...bunch of numpties. I backed out for one main reason...they don't recognise 'estimates' only quotations...they won't let you provide an estimate only a quote as they say customers have to have a fixed price...I said thats impossible...what about unforeseen works...well for all unforeseen works you have to contact the customer and provide a new quotation and wait for it to be accepted before proceeding...I said I'd never leave the office.
The run the business a bit like Jeremy Corbyn would a socialist/communist experiment.
