Never been refused, although have been asked to hold and they fly me in a vectored box north of the airfield not below 3000 ft.
There is a published NDB hold and procedure over the EME and EMW at East Mids at 4DME. No way they would position a SEP their above holidaymakers coming down the ILS.
Phraseology on the clearance or non-clearance (eg hold) for the approach is immediate and heights and headings when cleared are standard and expected. Flew the ILS on Saturday last and pre-empted every height and heading change they gave.
We have had some late turns to close the localiser and have flown through it. No big deal at 100kts. Problems can arise when they turn you in close to 6 DME. You haven't finised descending the ATC instruction to descend to 2000 ft and are waiting for the localiser to make a move. Around 6 DME, the glide comes straight in and every bit of your skills are then taken in capturing both the localiser and glide at the same time.
