Fireworkguy scoops another award !

The Underground Bunker is once again home to a new award. The Firework Guy (also known as John) was nominated for an award for his 'Immense Contribution to the Community'. He was presented with his award by the Mayor, Coun Tim Shepherd and PSCO Jonathan Bentley at a ceremony at Barnsley Fire Station. Working closely with the police and fire service, John helped to ensure there weren't any firework-related incidents last year in the area for the first time. The police recognised John's dedication to working with the local authorities and running a professional service in the shop and wanted to nominate him for this community award. John's extremely proud of this achievement and thrilled with the award but would like to thank the local people who've embraced the community spirit. You'll find the award, proudly displayed at the underground bunker.

The Underground Bunker - Now even better for 2015!


The Underground Bunkers showroom is stocked and ready for the New Year season. Classic barrages are back in stock, Olympica, Brazilian Bombshell, Quantum Power and the amazing Caged Tiger Pro. In the rocket section we have the Awesome new Weeping Willow, Doppleganger, Fright Night and Terminal Velocity rockets which are joining the classic Big Brother, King and Resurrection Rockets. These are as big as they come and, at the Fireworkguy with our 1.3g high hazard storage you're only paying for the rocket, they're not in the pyromesh packaging which costs so much. And of course, we have all the excellent favorites you keep coming back for. Remember, we are situated just to the back of "Hot and Tasty", the premises where we have been for years. This year again we have extended our car park, so just drive inbetween Cundy Cross Cars and Carters Hair Salon off Grange Lane, Cundy Cross and enter directly into our private car park.


1.3g High Hazard Fireworks

Stocking 1.3g class "high hazard" product has certainly given us advantage over our competition, who often stock large ranges of watered down 1.4g basic fireworks. The investment to our storage facilities both on and off site has proved invaluable. Once again, our 2014 rocket stocks are second to none. At the FireworkGuy, you are paying for the rocket not the packaging. This is why we attend industry events and displays throughout the rest of the year, to achieve the best range of great performing pyrotechnics for you.


BOGOF Offers 

As a specialist outlet, we source products where the price reflects performance related value for money. If you don't want to be looking enviously over the fence, then a visit to the FireworkGuy is a must. 


As Seen on the BBC...

Thank you to the Barnsley Chronicle and BBC Radio Sheffield, Toby Foster Breakfast Show,  who both ran pieces about THE new firework, "Long John". This has been named after our very own Firework Guy, John. Royal Party Fireworks, a Swedish brand, named the firework in honor of John for his outstanding work with the firework company in 2008 and 2009. Long John is almost 4ft and is probably the tallest firework on sale. It fires 95 large shots in under a minute, in a left to right 'machine gun style'. Call in and have a look at the firework for yourself! It's on display at our Cundy Cross store or visit the Barnsley Chronicle or the BBC websites.




Safety at firework displays is paramount. For those wanting further guidance: Health and Safety Executive publish two guides, HSG 124 'Giving Your Own Firework Display' and HSG123 'Working Together on Firework Displays'. Also see
