Nothing can replicate meeting people and striking up relationships. You can’t grow as a business in the right way unless you are properly connected with your audience and that is what Futurebuild does and that’s why it’s the right place for us.
We decided to sponsor and exhibit this year which gave us the opportunity to meet a wide range of different people within different roles in the construction industry. We had a rich conversation with lots of people including architects, designers, specifiers and end clients abut the things that are important to your business.
What makes Futurebuild unique is the targeted audience. If you’re speaking to someone here, you’re speaking to a B2B audience, to a buyer which generally means our conversations are better and more targeted.
What a fantastic Futurebuild event this year. Brilliant to see the National Home Decarbonisation Group (NHDG) Hub full of our members supporting retrofit at scale and more importantly supporting innovation through the 'Big retrofit challenge.
