Our Clients Say....

  • Recruitment@Rainbow HR has supported the extensive recruitment activity being undertaken at Porterbrook during a period of growth and organisational structural change.  Key roles appointed include Head of Fleet Services, Refranchising Manager, PMO Co-Ordinator, Head of Digital Services and Engineering Audit Manager.  All recruitment is carried out by HR professionals with a background in rail at a senior level and we offer a high-quality approach for just a 10% fee.  Kate North, Head of HR for Porterbrook, said of the service delivered:

    "I have used Rainbow HR for recruitment to support transformational change within our business over an 18 month period. Fiona’s first priority was to understand our business culture and need. That understanding enables her to recruit the right people with the right skills for us. Her knowledge of the rail sector is excellent, and I have always found her to be professional and responsive when priorities change. I would highly recommend the service Fiona offers as a recruitment partner."


  • "Rainbow HR (Fiona) was critical in facilitating my appointment as Head of Digital Services for Porterbrook Leasing. The prompt and personal approach made the process seamless and aptly targeted. It has resulted in a successful match of skillset, requirements and experience."

    Steph Klecha, Head of Digital Services, Porterbrook Leasing

  • "I would like to take this opportunity to thank you and all at Rainbow HR for your help and guidance through the selection process when I applied for the Lead Auditors role with Porterbrook.

    It was easy to talk to you regarding my up and coming interview and it was helpful prior to my interview that you gave me some information on the interviewees and Porterbrook as a company.

    I felt totally prepared when attending the interview which, with your help and guidance went very smoothly.Once again a big thank you for your help through the process."

    Tony Brian Wykes, Lead Auditor for Porterbrook Leasing Company Limited in Derby

  • "As a candidate looking for my next role, I am always mindful of the experience I have had with a recruitment agency as a job seeker. If they treat me with dignity, respect and care as a candidate, you can trust they are representing the best interests of the business they are sourcing for!

    And in turn, as an employer, you want to protect the employer brand you have taken great care to build. This is why it’s even more important to me having lived the experience as a candidate, to only engage recruiters who I can trust to keep our business values and ethos at its heart, when representing us.

    It was this perfect balance between employer brand and candidate experience that led me to first experience Fiona Irvine and her wonderful team as a candidate and later as an employer. They make it their business to match candidate and business with such precision and focus – you can trust you will have a winning outcome."

     Sukhdeep Dhesi, Head of People & Culture, cifas 

  • "Fiona was instrumental in my successful placement as Reliability Task Force Lead at Porterbrook. Her knowledge and understanding of the business as well as her ability to extract key skills and qualities of candidates resulted in a perfect match between Porterbrook and myself.

    She helped to create that personal connection between my CV and the hiring manager to further strengthen my application. She has enabled me to take the next positive stride in accelerating my career forward."

     Chris Beales, Reliability Task Force Lead, Porterbrook

  • "Can’t thank Fiona Irvine and Tom Waddell enough for their support during my recent job search!

    They both offered advice and online webinars that were extremely useful when looking for my next job opportunity! During such a horrible time, the support and kindness both they and others have provided have been a positive I won’t forget.

    If you’re currently faced with looking for a new role due to COVID-19, I would recommend getting in touch with them."

    Rachel Stewart, Senior Communications Officer, NHS Lanarkshire
