n8n Self-Hosted Setup in Cardiff
Setting up self-hosted n8n for Cardiff organisations, where the encryption key is the thing to protect above all else. Stored credentials are encrypted with it, so losing that key means every connection in every workflow has to be re-entered by hand — which for an established estate is days of work and several forgotten passwords.
Why this comes up
The problem
The instance was rebuilt without preserving the encryption key and no stored credential can be decrypted.
What you get
What we deliver
- Encryption key generated deliberately, recorded and backed up separately
- External database configured rather than relying on the default file storage
- Queue mode assessed against expected volume before it becomes necessary
- Backups covering the database, and tested by restoring elsewhere
- Access secured, since the interface exposes credentials and execution data
- Upgrade path established, as self-hosted versions move at a reasonable pace

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

n8n Self-Hosted Setup in Cardiff — common questions
- Why is the encryption key so critical?
- Because it is the only thing that can decrypt stored credentials. A rebuild, a container recreated without the variable set or a migration that overlooks it leaves the workflows intact and every connection unusable — recoverable only by re-entering each one.
- Is the default database adequate?
- For evaluation, and not for anything you rely on. Moving to PostgreSQL early avoids a migration later, handles concurrent execution properly and makes backup straightforward — it is a small amount of setup that prevents a predictable problem.
- When is queue mode needed?
- Once executions overlap enough to compete. A single instance processes workflows in one place, so as volume grows or individual runs take longer, separating the main instance from worker processes is what keeps throughput reasonable.
- How exposed is the interface?
- More than people treat it. Anybody reaching it can view execution data — which contains whatever passed through your workflows — and modify automations, so it should sit behind authentication and network restriction rather than on the open internet.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
