Find fire safety tenders. Get found by clients.

Fire safety knowledge in action. Expertise within reach. OpenFire is the digital infrastructure for fire safety. Fire safety companies use it to hear about the tenders that fit their work and to be found by clients. Anyone who needs fire safety expertise (architects, developers, building owners, contractors, reviewers, manufacturers) uses it to find those companies. And for fire engineering it offers 83 transparent methods from 9 documents, with specialist AI support.

We gather fire safety tenders from across the web and sort each one by the fire safety work it involves and where it is. With Directory Premium they are matched to your listing's specialisms and locations, which you can change, and the new ones are emailed to you every week. Tenders cover the UK today, and other countries are coming soon.

Any company with a listing can see how many tenders have matched its work recently. The tenders themselves, the weekly email and tracking what you bid for, won and lost come with Directory Premium.

Free: listing and claiming a company, the whole directory, every method with full calculation sheets, the articles, and Ember AI up to a monthly allowance. Directory Premium, £50 a month per company, adds matched tenders with a weekly email, a Sponsored spot in the directory, market insights and project photos.

If your company is already in the directory, open its profile and claim it, then keep its details current yourself. If it is not listed, add it from your account settings and publish it when you're ready. You control whether it is live. Claiming and listing are free.

Search the directory by category, specialism, country, region, city or company name. It covers 3894 companies in 68 countries, across 49 specialisms. Each listing sets out factual information: registered details, offices, years in practice and stated scope of work, so you can compare companies on the same basis.

No. A listing is a factual record (registered details, offices, specialisms and stated scope), published so companies can be found and compared. OpenFire does not select, certify, approve or recommend the companies listed.

It removes the searching and the rebuilding. You search one catalogue instead of tracking a method across handbooks, codes and inherited spreadsheets; you see the source, assumptions and limitations behind it; and you run it in the browser, with a full calculation sheet others can follow.

Ember is grounded in fire engineering methods and terminology, and it is wired to the calculation engine rather than asked to imitate it. It can find a method, explain its scope and inputs, fill the form in and run it, but the number comes from the tested implementation, not from the model.

Each method is implemented once, in the open, and tested against values published in the document it comes from. Those tests are in the public repository. That checks the implementation against its source; it is not an independent validation of your design, and it does not remove the need for review.

No. It makes methods, assumptions and limitations easier to inspect, so decisions are better informed. Choosing a method, judging whether it applies, and responsibility for the design all remain with the competent professional.

No. Tenders, the directory, the methods, calculation sheets and Ember AI all run in your browser, on a laptop, tablet or phone. There is nothing to download, install or keep up to date.

The calculation engine is. Every method comes from the open-source OpenFire library (MIT-licensed). You can read and audit it on GitHub, use it from Python (ofire on PyPI), or contribute methods and test data.

OpenFire is developed and maintained by Emberon Tech Ltd, a technology company based in Edinburgh, Scotland, combining fire safety engineering and software expertise.
