  • “Lotus Homes are an award winning Residential Developer based in Banbridge. We are currently developing residential housing sites in Banbridge, Newry, Lurgan and Warrenpoint and will be shortly commencing developments in Antrim and Belfast. Lotus Homes have been using ICW as a provider of Structural Warranties and Development Bonds for all of our sites for over 12 months. We have at all times found ICW staff to be very professional, helpful and easy to work with.
    ICW are based in Belfast and have a dedicated inspector who carries out stage inspections on all our sites. Their systems for issuing final certificates are very straight forward. I have no hesitation in recommending ICW as a provider of Structural Warranties and confirm that Lotus Homes will continue to use them on any new developments we commence”.
