Outsourced HR

  • Overview

    HR requires specialist knowledge, it’s the most changed legislation affecting a business today and it’s impossible for senior management to keep on top of it and do their day job!

    Our CIPD qualified professionals can deliver everything you need to run an effective and compliant HR department – in the way you need it delivered.  Our HR options range from simple HR administration to a fully managed, outsourced HR and payroll service – and anything in between.

  • Foundation service

    Our Foundation Service is ideal for emerging or smaller organisations seeking to introduce compliant and effective employment arrangements.  We will sort out all the nitty-gritty details for you like employment contracts, an employee handbook as well as policies and procedures – putting the business in the best possible position for growth.

    The foundation service includes:

    • Provision of a compliant framework of employment documents, policies and procedures, which are updated as HR legislation or the business itself changes
    • Design and delivery of tailor made contracts of employment and employee handbooks
    • On-demand email and telephone advice to support you in managing employment issues and problems.
    • Access to optional ongoing HR consultancy and day to day outsourced HR advice.

    Our Full Service is perfect for thriving businesses requiring more comprehensive HR support.  It provides all the benefits of an inhouse team without the expensive of employing your own.  As with the Foundation Service we will sort out all the nitty-gritty details and keep you on the right side of employment legislation, but with our full service you can select individual service elements and tailor it to your specific requirements.

    The Full Service can include the following elements:

    • Managing all routine HR related issues, as well as issuing employment contracts, managing payroll and benefits administration and confidential handling of personnel files
    • Providing advice to managers on how best to handle HR and employment issues and problems

    I-Demand is ideal for small and medium-sized businesses looking after a handful to a few hundred employees. With online delivery and powerful features, this system offers everything you need to streamline your HR administration and cut costs, including:
