Orion Heritage is the UK’s largest independent heritage consultancy.
Since 2015 we have advised developers, planning teams, landowners and land promoters on some of the country’s most complex and high-value development projects.
Our independence is fundamental to how we work. Because we do not undertake archaeological contracting or other delivery services, our advice is always clear, proportionate and evidence-led.
Where projects require specialist delivery, we manage every step on behalf of our clients. This includes agreeing the scope with local planning authorities, seeking tenders from qualified contractors, overseeing fieldwork, liaising with archaeologists, and advising clients on the implications of the results. If further mitigation is required, we repeat this process — ensuring the right work is delivered efficiently, at the right price, and within the required timeframe.
This allows us to focus entirely on what our clients need most: robust heritage strategy that supports successful planning outcomes.
