It depends. 

If you want a quote for a light fixture change then no. Lights take around an hour to change unless its a chandelier which will incur an extra charge, therefore the chrage will be the hours rate. 

If on the other hand you are having an extension done and need to talk through your project and need me to liaise with your builder, then yes. 

I charge for this service because I offer my intellectual property as part of the quotation which has needed to be written and detailed based on what we have discussed. 

If you then decide to contract me to do the works for you, the cost of the quotation is then taken off the final bill. 

If you don't want me to do the works, you are still able to keep the specification that we have produced to then take to someone else for quoting.
