UltraSIPs Ltd supplies structural insulated panel (SIP) kits across the UK for garden rooms, extensions, outbuildings, home offices and self-build projects. We work with homeowners, trades and developers who want faster build times, strong thermal performance and a straightforward kit process. Our kits are built around high-quality SIP construction using OSB faces and PIR insulation cores, with panel options to suit different project requirements. We provide cut-to-size panel packages, splines and structural components so customers can move from design to installation with confidence. We also offer technical support, CAD/drawing services and practical guidance for self-builders and installers. At UltraSIPs, we focus on clear communication, realistic lead times and transparent quoting. Every project is different, so we take the time to review layouts, openings and structural considerations before finalising specifications. We’re always honest about what is included in a kit and what is not, so there are no surprises later. Our goal is simple: deliver reliable SIP solutions and responsive support from first enquiry through to delivery. If you’ve worked with us, we’d really value your feedback on product quality, service, communication and overall experience. Your reviews help us keep improving and help future customers choose the right SIP supplier for their project.

I highly recommend Jacob and Ben from UltraSIPs. They were helpful and always responded fast to my messages. They provided detailed drawings to allow my build to complete without any problem. Their prices are very competitive. Hope to use this company again in the future. Thanks quys.
Compelled to write a review as the quality of service and products from UltraSIPS has been fantastic.
As a reasonably competent DIYer, I was keen to build a 5mx4m gym using SIPS. The product offering from UltraSIPS seemed superior to all others that I investigated.
What really impressed was the brilliant website that has been developed that enables detailed design work to be undertaken. The depth of resources available to dive into to understand the build process is super.
All my questions were promptly answered and the final delivery took place practically to the minute of agreed time.
Well the building is up .. yey! It took 1.5 days to assemble and it was a total breeze.
For anyone interested in having a go at building a garden room .. or much larger building, I would definately say have a go using SIPS, it is a game changing approach and the service, support and products provided by UltraSIPS are 1st rate.
So refreshing for a company to do exactly what they say, from concept drawings , being in touch throughout and delivering on time. Great experience from start to finish and we shall be using them again Its a 10/10 from me
