What it is
Practical HR support for small businesses that have no in-house HR team: contracts, handbooks, disciplinaries, absence, grievances and day-to-day people questions, mostly done by phone, video and email.
Your first three steps
- Write down the services you will offer and set a simple retainer and day rate after checking what local HR consultants charge
- Arrange professional indemnity and public liability insurance, and register as a sole trader with HMRC
- Tell past colleagues, local business groups and your LinkedIn network that you are taking on clients, and offer a short free call
Who pays
Owner-managed businesses with a handful to a few dozen staff, such as shops, trades firms, care providers and hospitality businesses.
How it makes money
Monthly retainer for ongoing advice, fixed fees for documents and projects, or a day rate for bigger pieces of work.
Skills that help
- Solid HR experience or a recognised qualification
- Knowledge of UK employment law basics
- Clear, calm communication
- Discretion with sensitive information
Watch out for
- Professional indemnity insurance, as bad advice can lead to claims
- Employment law differs slightly between Great Britain and Northern Ireland, so check which rules apply to each client
- Data protection: you will handle personal data, so check whether you need to register with the ICO
- Do not give legal advice beyond your expertise; know when to refer clients to an employment solicitor
- Income can be uneven at first, so build a few retainer clients early
