A UK-accredited, practitioner-led health & safety provider — NEBOSH Gold Learning Partner, IOSH-approved, and independently certified to ISO 45001, 14001 and 9001.
KeyOstas is a UK-accredited health and safety training and consultancy provider with roots going back to 1984. Originally founded as OSTAS, we acquired The Key Consultancy in 2011 to become KeyOstas Ltd — bringing two complementary teams together under one independent UK business (Companies House 06294367).
We are a NEBOSH Gold Learning Partner — provider 009, one of the lowest partner numbers in the UK, signalling a long-standing relationship with NEBOSH. We are also approved by IOSH, CITB, ITSSAR, the Safety Pass Alliance and ISEP, and independently certified to ISO 45001 (occupational H&S), ISO 14001 (environmental) and ISO 9001 (quality management).
From our headquarters in Southam, Warwickshire, a team of 20+ core employed consultants and a wider specialist associate network deliver public courses online and on-site, in-company training nationally and internationally, and end-to-end consultancy — from one-off risk assessments and Fire Risk Assessments to our Bronze, Silver, Gold and Platinum H&S management packages.

We don't sell motivational slogans. We deliver the qualifications, audits and on-site support that keep your people safe and your business compliant — and that pass NEBOSH, IOSH and HSE scrutiny when it counts.
Every lead trainer holds the NEBOSH Diploma, full CMIOSH status and at least a decade of operational experience — on construction sites, factory floors and oil platforms. When they teach risk assessment, it's because they've done it for real.
We hold ISO 45001, ISO 14001 and ISO 9001 — independently audited every year. Every course is documented, version-controlled and reviewed against learner outcomes. NEBOSH Gold requires pass rates and satisfaction above national averages.
Our courses pass because we explain regulations the way they actually work in your workplace, not the way the legal text reads. No mumbling through generic PowerPoints.
We are not part of a plc or owned by an investment group. KeyOstas Ltd is a privately held UK SME — which means we answer to clients, not to shareholders.
One accredited provider, one point of contact — for qualifications, in-company training and ongoing health & safety consultancy.
One of a select group awarded NEBOSH Gold status (provider 009). Lead trainers hold the NEBOSH Diploma + CMIOSH and have delivered the General, Diploma, Construction, Fire, PSM and HSE Leadership courses for two decades.
Independently certified to ISO 45001, ISO 14001 and ISO 9001. Every course is run under audited management systems — not just promised.

Public courses online and at our Southam HQ, plus in-company delivery anywhere in mainland UK. Trusted across construction, manufacturing, energy, logistics and the public sector — with a 4.8★ Google rating.

Most clients use us for both.
