The new free WBRC show at Nightflix is on November 5. The traditional WBTP one at Country Market is on November 3.
Curtis Bone, of the WBTP, said: “The firework display we hold at Country Market was taking over from the garrison in 2015 when they left.
“We took over so the town continued to have a display and to keep the tradition going. The display has been going for more than 35 years and is something we are keen to keep going.
“We do charge entry, as we receive no outside funding for the event, and as you can imagine it’s an expensive event to run. As a charity we make no profit from the event, and run at break even at best, which is why the free event concerns us.
“It will have an impact and we are going to lose income because of the WBRC.
“What’s annoying is it’s likely to be a one-off for the WBRC, as once construction starts the site would be even more inappropriate than it is now.
“We only knew about the fireworks once it was on Facebook. Originally it was £12 a ticket and then suddenly changed to free.
“At no stage did the WBRC approach us or offer to work with us on our event. Relationships between the WBRC and the WBTP have hit rock bottom and are unlikely to recover.
“It’s a shame that the town is being spilt into two because of the developers and their actions, and residents are becoming concerned.”
WBRC project lead James Child said: “We have supported the WBTP fireworks at Country Market for a number of years through the provision of volunteers, and we are happy to do so. We truly value the working relationship we have with those representing the best interests of the community.
“This is being fully funded by the WBRC and is being used as a charity event to fundraise for the local foodbank and the community trust, organisations that support the local community irrelevant of how long they have lived there.
“We have had 2,500 people sign up for the event which, rather than being divisive, strikes me as a great way to bring old and new residents together, as well as attracting visitors who will come and spend money with local businesses at The Shed.”
