The six-year-old is the 9-1 ante-post favourite with the sponsors for the valuable handicap hurdle after showing smart form when placed in good novice contests on his first three starts over jumps following a successful bumper campaign.
"All is good with Lalor. He is pleasing us and going nicely. We are looking forward to Newbury with him," said Woollacott.
"He has a nice weight for the Betfair Hurdle. I said at the start of the year we would like him to be rated between 133 and 137, and that is where we are at the moment.
"Everything has gone to plan and it's just a question now of whether we are good enough. We wouldn't want really heavy ground - that would probably be our biggest worry.
"He has a similar profile to Ballyandy who won the race last year and that is why I said at the beginning of the season that if we are going to be good enough for the Supreme or the Ballymore at Cheltenham (in March), we need to be rated 150 and the Betfair Hurdle is a good test along the way. If Cheltenham comes too quick, then we could always wait for Aintree.
"If we are not good enough, then we are not good enough. With the wonderful prize money on offer for the Betfair Hurdle, it's certainly worth trying for."
