In our 20 years of Umbrella service our contractor base has grown largely through personal recommendation as well as a bedrock of contractors who just keep returning for our quality service, and we are therefore without a sales team or a sales pitch. We are committed to transparent, prompt and communicative service. There are no hidden charges; there is support with the complexities of the thorny issues such as holiday pay and expenses. Our company values, objectives and philosophy are a direct reflection of the kind of service culture we want to inspire where everyone involved is driven to create a world-class next-generation workforce.
