Read the waranty conditions for your new boiler VERY CAREFULLY most wont honour a guarantee if the system has not be Powerflushed withg a certificate has a magnetic particle filter fitted to the heating return, will not honour problems associated with limescale if a suitable scale reducer is not fitted ..... all of these things are the very items that a one day merchant will omit from the job ... so look very carefully at what you are getting for your cash ask for a written work schedule with your quotation!!
Manufacturers dont as for a power flush let alone a certificate they dont ask for a magnetic filter some ask for a scale preventor.
What they ask for is the system to be cold and hot flushed and left to a certain stand which can be achieved without power flushing.
OP WHY would you worry about about cheaper quotes dear does not mean good as cheap does not mean shoddy
may i enquire as to which which boiler you got for under £400??
