We employed the Invisible Group over a period of some two years in a phased project. They gave a good service as far as the finished product was concerned and gave good technical advice all the way through the contracts. They were able to deal with variations to the contract as they arose and were not ‘claims’ oriented in their approach. As this location dealt in part with a 1960s block of high value flats, they had dealings with both individual residents as well as the Maintenance trustee and we were pleased with their approach in this respect.
