I have only ever ordered from Screw Fix 4 times before and every time
their next day delivery has not materialised. it has always taken
between 3 and 5 days?

So this time I paid extra for before noon 12 next day delivery in the
mistaken belief that may parcel would turn up.
I waited in all day yesterday and nothing turned up !! I live in
London!!
I rang Screw Fix who said it was with Parcel Force.

I rang Parcel force today and they said It was still with Screw fix?????

I have wasted a whole day off and Screw Fix have still not delivered!!
but they have offered to refund my £4 postage for before 12 noon
delivery cost!!!!

they say they have 97% next day delivery, this can't be true.

Would I be right to demand compensation?

Like most other replies, I get very good next day service from screwfix.
They now send an email when they dispatch so you should be able to tell
where the fault lies.
No consolation to you but I suspect the problem my lie with where you are
requesting delivery and the carrier and not Screwfix's fault. A couple of
years ago they went through a bad patch on delivery times (and packing
quality) but they really have improved since then.
