Community & CSR

Supporting the places where we live and work

JJMac supports local charities, community projects and grassroots football and rugby teams. We organise company fundraising events, provide practical help to families experiencing hardship and are proud to create employment opportunities within our local community.

Our commitment extends beyond financial support. When essential PPE was urgently needed during the Covid-19 outbreak, our surplus supplies were delivered directly to a hospital that had requested help.

JJMac completed the project in a professional manner, within budget and working to our unrealistic timetable.

Jason Dixon
Construction Manager, HPC Homes Ltd
JJMac were contacted to convert our caravan storage area, including the large bund walls around the perimeter, to a more useful storage area. This they did with complete professionalism and the results were very pleasing to Delta’s personnel and the many lorry drivers who regularly visit the site. We can now use the whole storage yard for the first time in 20 plus years.
