Great customer service
I had such a great experience with Josh! He was reassuring and responsive. My issue, which had been caused by an oversight by my conveyancer, was handled efficiently, and Josh made sure everything all my questions were answered promptly. He also provided timelines and carefully explained to my step by step the process of obtaining the final warranty certificate for my home.

the time it took to get certificate numerous phone calls told someone would call me back no call back the person Ronan falsey went above and beyond to sort out problems caused by another Surveyer if all of the staff acted like Ronan your company would get 5 stars
A Genuinely Positive Experience
Advantage Warranty and the AHCI Structural Defects Warranty team were excellent throughout the process.
Communication was clear, prompt and professional from start to finish, and the whole team dealt with matters efficiently and with a proper sense of responsibility. In particular, Ronan managed the project very well, kept things moving, and was always helpful, knowledgeable and straightforward to deal with.
What stood out most was the team’s willingness to stay engaged, deal with issues properly and work towards the best possible outcome. That level of service makes a real difference.
I would have no hesitation in recommending Advantage Warranty and the AHCI Structural Defects Warranty team to others.
Avoid this company
ACHI firstly changed surveyors mid job, without telling me, so I was calling and leaving messages with someone who had left the company. The new surveyor had no knowkedge of my build. Despite the final visit in January, Im still awaiting the completion certificate, Khurrum keeps telling me they have all the information, and the certificate will arrive in 2 day, 3 weeks later, he is still asking for more paperwork to he signed. If feels like they are only interested in sales and nit customer service. Ive asked put in a conplaint 3 times now, still no response. If this is how they treat customers when issuing the policy, what chance is there if you ever need to claim. Avoid this company!

I had an excellent experience working with Advantage Warranty. The team has been professional, responsive and genuinely committed to helping the project progress, even when challenges arose.
In particular, Mr Ronan Falsey provided outstanding support throughout the process.

I would also like to thank Derek Byrne for his assistance and professionalism during the process.
Their dedication and willingness to help truly reflect the high standards of Advantage Warranty. I would strongly recommend Advantage Warranty, especially Ronan Falsey and Derek Byrne, for their excellent service and support

Professional surveyors and excellent service
I recently had a site survey completed in one of my projects in London, Chelsea’s and I couldn’t be more impressed with the entire experience. I want to thank the surveyor who inspected the project Mr Ronan F, who was very knowledgeable, and well coordinated. I’m very happy with the level of professionalism as straight after the site visit I received the report with the findings and comments. As a contractor this is what I need at the end of the day, a company and people who are professional and don’t cause any delays to the project. Highly recommend!!

Can highly recommend
As a company offering warranties on our builds, we have used AHCI (specifically Derek Byrne) for a few years. He has always been professional, approachable and helpful.
Whilst not the cheapest on the market, we feel that paying that bit extra gives both us and our customers the reassurance that we need...
Great Service…
Efficient service for a retrospective structural warranty. Max Sumner dealt with my policy quickly and professionally. Highly recommend
Efficient & reliable service every time
We’ve been using AHCI for several years now, and they’ve provided warranties for more than 50 of our units to date. They’re always very efficient, well priced, and make the whole process straightforward. It’s been a great partnership that gives us confidence our developments are well covered.
10 year warranty expience
We moved from our existing warranty provider to Advantage for our 10 year warranty a few years ago. They were incredibly reasonable in comparison and Derek, our account manager, has always been responsive and helpful as has our surveyor. I would definitely recommend using them again.
ACHI - Structural Warranty Review
AHCI provided a competitive quote for structural warranty on recent projects in North London and the Midlands.
Joe Deary was very helpful in setting up the policy and was on hand to advise where needed and was very responsive in answering any queries. Very quick and smooth process.
The inspectors are first class, and the aftercare and onward management of the policy has been great.
I would happily recommend the services of AHCI for structural warranty cover.
10 Years structural Warranty
We’ve been using Advantage for our 10-year structural warranties over the past couple of years on our developments in Norfolk. Our account manager, Max, is a real credit to the team — always responsive and efficient, often turning around enquiries and paperwork on the same day. As a developer, we wouldn’t hesitate to recommend Advantage for their excellent service and reliability.
