agile, i havent forced anyone to come round the house. all the tradesmen have done so voluntarily. i presume them wanting a site visit is something to do with with being able to provide an accurate quote for the job. some tradesmen have been helpful and those tradesmen will be called back to tender for the route we have in mind. a few tradesmen however have had scant regard for what we want, and what is allowable on a listed building, and perhaps just had in mind the highest charges they could get for the easiest (shortest) route. if i had just listened to some of the tradesmen and blindly accepted what they said, i may have a boiler flue exiting the front wall of my house now in contravention of the opinion given by the local listed building officer. i know full well to listen to the expert so you dont have to tell me to do so. i simply check what im told is correct. it always pays to be informed as a customer!
newgasinstaller, what a teribble attitude, if that is your charging model, then it seems to me you're overcharging those who have the audacity to want to cut their costs by doing prep work. i expect you prefer a customer who is entirely unknowledgeable then people like you and agile you can just pluck prices out of the air!
bengasman, i am looking at an entry level range cooker, circa £400 to £500 and a 30 to 35kw boiler. i will cut my cloth to fit by getting a cheaper cooker rather than risking sub optimum gas pipe infrastructure.
