I have been a customer of SBI Ltd for a number of years. I am extremely pleased with their conservatory roof sails, which do a great job of providing shade, while looking much smarter than conservatory blinds. I’m also pleased with their Phantom screens, which keep insects out, while also providing shade as they allow fresh air in. SBI’s after sales care is second to none and it is clear they value their customers. Highly recommendedSince my last review I have had cause to use SBI Ltd again, this time for something urgent. As expected they were extremely helpful and efficient. The job was done totally fuss free by a very pleasant installer (I don’t think SBI employ anyone who isn’t pleasant). I’m now the proud owner of mirrored windows that keep out the prying eyes of a very nosy neighbour.
