hup! Avis 

Product is good but it must be measured and installed properly. The recommended installer we had was not good. Wall was leaning and gap in roof. Took them 6 months with many no shows.
Ultra frame have no control over the installation you are left on your own to sort it out.

Samantha was very informative and friendly in dealing with my enquiry.Thanks Sam!

We’re sharing our experience in the hope that it prevents others from going through what we have.

Earlier this year, we decided to proceed with a Hup! Home extension — a product owned by Ultraframe and promoted via the Hup! Homes website.

We were drawn in by the speed, efficiency and design — and the system’s endorsement by a well known architect on TV, further reinforced our confidence.

We chose to work with AB Design & Build, the only builder listed on the Hup! Homes website as covering our area. Initial engagement with Stuart (the owner) was promising — he was responsive and confident, and we even spoke with a current client as part of our due diligence.

However, after paying a £17,000+ deposit, the experience deteriorated:

* Communication dropped
* Work schedules slipped
* Materials for the build were left on our lawn for over 5 weeks, even though Ultraframe confirmed they should only be exposed for a maximum of 48 hours. We later learned AB Design & Build hadn’t even paid for the materials, despite receiving our deposit.

The foundation wall built by his team had to be demolished, as confirmed by Building Control, who found it non-compliant with building standards.

And most recently, we discovered a shared water pipe had been concreted over without a lintel, breaching Building Regs (Approved Document Part H). Further to this, we were forced to pay an additional £6,000 to undo the work that had been done and discovered one of the said pipes was cracked and full of concrete.

Despite persistent follow-ups, we’ve only received a partial refund, we remain out of pocket, and now face an additional £28,000 in unplanned costs to bring the project back on track.

That trust has come at a major financial and emotional cost. We trusted this builder because he was listed directly on the Hup! Home website. That listing gave us confidence — and it has cost us dearly.

We can't comment on the HUP extension itself as this experience put us off, especially as Ultraframe wouldn't take any responsibility, even though they listed him as an installer on their website. We would never have come across AB Design & Build (they're a good 45 minutes drive from our home) had it not been for finding the company listed by Ultraframe.

If you're considering a HUP extension, please learn from our experience and do your own thorough vetting.

I have been using Ultraframe for a number of years.
Good products and good service.

I have worked with Ultraframe for years, and this product like the rest exceed the standards of competitor products by miles!

Not only is it an excellent and innovative product the Service and attention to detail from the team at Ultraframe is second to none. The support they offer with thier products is excellent, and when it comes to HUP! in Scotland we couldn't ask for better.

We are so delighted with the transformation of our old conservatory into a modern extension using hup. It took just a few days to build the main structure and the whole thing was finished and plastered etc in 2 weeks. We opened the space into our kitchen by removing the old doors and now have a gorgeous, open plan modern space that we live in all the time. Can't recommend hup enough!

Just love hup! It's fast to build, really easy to obtain building regs, looks amazing and great value for money.

We are a supplier of the hup system to our residential clients and we have found the product, service and technical support behind the product to be excellent - such that it gives us the confidence to present this product to our prospective customers as a valuable option to be considered when planning their home improvement projects

We had an extension built on our home using hup! and it was a fantastic experience and has totally transformed our home. Our full-width extension was built and watertight in only 4 days ready for the electrician and to be plastered and finished internally. The speed of the build was very important to us as we wanted as little disruption to our family life as possible and with hup! this is what we got.

Fantastic and innovative system and company to deal with. This is the future of building and we get great feedback from our customers of its energy efficiency and speed of build. Highly recommend.

So glad we chose Hup system we had a conservatory knocked down and replaced with Hup system never looked back ! It went up in no time but was solid and we absolutely love our new space it’s cosy and looks fantastic so many pluses it’s a win win !

The HUP wall and base system is simply fantastic. We’ve completed many installations, and every customer has been delighted with the results. The system is incredibly quick, creates very little mess, and requires almost no drying time.

All in all, it’s an outstanding system – keep up the great work!

We have used hup! on a number of projects and find it to be an innovative way of building giving the client more floorspace and increased insulation.

Great product, out performs conventional builds in thermal performance, speed and value. HUP! is the future of home extensions.

We went with the hup! system for our extension and I’m so glad we did. The whole thing went up so quickly compared to a normal build barely any mess or disruption. The finished space looks amazing, feels really solid and cosy, and has completely changed how we use our home. Everyone who’s seen it has been impressed, and I still can’t believe how fast it was all done. Would definitely recommend the hup! system to anyone thinking about adding some extra space. We got to see a hup! extension on display at the 5 Star Windows and Conservatories showroom in Kidderminster. They were our closest builder. Would also recommend them!

We’ve completed several HUP installations this year, and they’re becoming increasingly popular. One of the big advantages is the design flexibility: slimmer pillars, shaped walls, and more creative layouts that simply aren’t possible with traditional builds.
Another benefit is that HUP provides full structural calculations for every design. This not only saves our customers the cost of a structural engineer but also removes the delays and inconvenience that often come with that process.
Our customers also appreciate the speed of the build and the increased internal floor space compared to conventional methods. For all these reasons, we would highly recommend HUP as a modern, efficient, and innovative alternative to traditional construction.

As a builder, we came across HUP! late last year, saw it as a new way forward from a traditional build concept and became approved installers for HUP. We are currently building our 5th HUP extension. We have to say the product quality is excellent, and likewise, are the timescales from order to delivery. If we have any questions or complications regarding the erection process the HUP technical team are helpful, very knowledgeable and on hand to give advice when needed. Our HUP build customers have been pleasantly surprised by the speed and efficiency of the whole process. Obviously, part of this is due to our own professionalism. We are looking forward to a long relationship with HUP moving forward through the coming years.

hup! deliver fast, fit great and so warm and cosy!!

Just over a year ago we transformed our old conservatory into a HUP! extension and we honestly couldn’t be more delighted. What used to be an underused space is now a warm, comfortable, and stylish room that feels like a natural part of the house all year round. Budget was a huge factor for us, and the cost certainty with HUP! gave us total peace of mind — we knew exactly what we were paying with no hidden surprises, and we stayed on budget from start to finish. The build was quick, the quality is outstanding, and the whole process was far less stressful than we ever imagined. We now have the extra living space we always dreamed of and use it every single day. Highly recommend HUP! to anyone thinking of upgrading their conservatory or adding an extension.

We are absolutely devastated and heartbroken by our experience with Ultraframe/Hup! and their recommended installer xxx (name removed at hups request). What began as an exciting project to replace our old conservatory with a modern Hup! extension has turned into a financial and emotional nightmare. We’ve lost tens of thousands of pounds and been left with an unfinished, unsafe building site attached to our home — and a back garden that’s been destroyed.

We found xxx (name removed at hups request) through Hup!/ Ultraframe’s “Find an Installer” tool, whereby customers input their information and Hup/Ultraframe pass the details onto one of their installers. We trusted (as many would) that this meant he was vetted, reputable, and aligned with the promises made in Hup!’s marketing and social media such as: “local, reliable, Hup! approved” builders, watertight builds in five days, a seamless single-supplier model, and energy efficiency “five times better than the average home.”

The reality couldn’t have been more different.

From the start, XXX was unreliable. His team was frequently absent and he ultimately vanished after being paid 90% of our total build costs. He mismeasured the build and then disappeared entirely — ignoring all contact, including legal letters. His former team told us he had changed address without informing us, and it appears he hasn’t even updated his company details and accounts with Companies House.

Despite Hup!/Ultraframe being fully aware that XXX had abandoned the project — and that we had already paid him in full — we were shocked to receive a solicitor’s letter on their behalf stating that he hadn’t paid them for the Hup! materials. The very next working day, we contacted the solicitors to explain the situation. Regardless, within 4 days we were sent debt collectors to our home to demand payment — from us. Even though we had already paid.

Hup!/Ultraframe admitted that XXX along with their other builders are not actually “approved” — and that they do not vet the installers they refer onto their customers on their website. This completely contradicts their advertising and public messaging. Throughout this ordeal, their support was minimal at best. It took two months for the technical team to amend the mis measurement issue. They referred us onto two other installers with minimal handover to the installer of the mis-measurement problem - one of whom did not respond and had little availability. The other installer they connected us with quoted £1,000 per day plus travel costs just to assess whether the existing materials were usable — a cost we simply could not afford, especially on top of what we’d already paid or to start again they wanted us to pay the same as the original build costs and that was with Hup/Ultraframe's supposed 'Preferential Discounts.'

Throughout dealing with them since April Hup!/Ultraframe refused to take accountability, and left us with no realistic or affordable way to finish the project.

Hup!/Ultraframe may promote their system via glossy ads and celebrity endorsements (such as XXX from BBC’s Your Home Made Perfect), but when things go wrong, there is no safety net, no accountability, and no real customer protection.

After nearly nine months with Hup! materials in our garden — ruining the grass underneath — we had no choice but to ask Hup!/Ultraframe to come and remove them, just to avoid having to pay even more to dispose of it ourselves.

This ordeal has had a devastating impact on our finances, our health, and our family life. We’ve lost tens of thousands of pounds, had to take time off work due to stress, and pay for storage for a kitchen we still cannot install. This isn’t just a failed home improvement — it’s trauma.

The Hup!/Ultraframe model — which involves referring customers to unvetted third-party installers while taking no responsibility when things go wrong — feels not only flawed, but potentially misleading under consumer protection regulations.

Please be warned: this is not the “fast, energy-efficient, one-supplier” solution it claims to be. Do your due diligence. And think very carefully before placing your trust in Hup!/Ultraframe, the Hup! system, or their “Find an Installer” tool.
