Any questions?
We are proud members of the hup! partner network.Choose us as your trusted hup! experts
Is hup! compliant with Building Regulations?
Yes, of course! All hup! components are fully compliant with the latest Building Regulations.
I’m worried about costs spiralling and exceeding our budget.
At the start of any hup! build, you will be given a written quote which will not fluctuate.
I’ve heard horror stories about home extensions, what makes hup! different?
Many of the horror stories associated with building extensions are due to managing multiple trades, weather delays and price increases – with hup! every one of these worries is eliminated. One team manages your build, most builds are completed in around 4-5 days and you will be given a price at the beginning of your build that is guaranteed.
Is hup! too good to be true?
hup! offers so many benefits that some homeowners have questioned if what they read about it can really be true – and have subsequently been reassured that hup! IS every bit as good as it sounds by homeowners who have already had their hup! built!
One of these homeowners is Sarah and you can read her hup! story here.
