Sefton Central Labour MP Bill Esterson fears that a limited 30 minute free parking for Maghull Central Square could drive customers away.
The MP has spoken to Square owners The Maghull Group, who are planning to introduce parking charges, to raise concerns about whether the planned 30 minutes is long enough.
Bill said Maghull needs to learn a lesson from Crosby Village where there is a limited 30 minute free parking.
Bill said: "I have discussed parking charges with The Maghull Group and asked them to consider how long parking should be free so that shoppers and traders both benefit.
"Maghull Group is proposing half an hour free parking, then to charge, which is the same as happens in Crosby. But when I visit Crosby, I find that half an hour is not long enough so end up paying for an hour or for longer.
"I generally find that an hour is long enough and most people I have asked about this have said something similar.
"I have therefore said to Maghull Group that if they are going to charge can they make at least the first hour free. This would mean people have long enough to shop for most things but would still mean a turnover of shoppers to help with trade, which is their reason for bringing in charges. Residents who live in the Square also need somewhere to park as do shop staff. I am also asking Maghull Group to look at residents’ permits and I am pleased to see that an extra 39 parking spaces are being built at the junction of Westway and Liverpool Road North."
Bill said the priority is to attract more shoppers back into the square.
Bill said: "The main aim of the Maghull & Lydiate Labour Action Team-backed Support Our Shops campaign is to get more people to use the businesses in the square.
"There is a problem at present where sometimes you can’t find a parking space as people park there all day, so some change in the current arrangement could help shoppers and traders alike.
"But we need to learn from other shopping centres in Sefton. In my view, 30 minutes isn't enough in Crosby and I am worried that the same will be true in Maghull. I have also discussed this with Sefton’s Labour Councillors and they agreed that in both Crosby and Maghull, they will look at parking as part of their plans to invest in our town centres.”
