Both are UK-built and GDPR-ready. The big difference is how you pay: HeimdallHR charges per employee and lets you switch modules on and off, while BreatheHR uses flat monthly tiers based on your headcount band.
BreatheHR is a UK-built platform with ISO 27001 accreditation and flat per-business pricing. HeimdallHR takes a more modular approach: you start with a low per-employee Core price and add only the capabilities you need, from a catalogue of 16 add-ons that goes deeper on compliance and HR operations. If you want predictable per-head pricing and room to grow into advanced HR, HeimdallHR is built for that.
