Firms that bid for public sector work are checked online before they are shortlisted. A clear, accessible site that meets public sector standards helps.
Website Design in CardiffMarketing agency Cardiff: websites, SEO and ads for Cardiff businesses.
We are based in London and work with Cardiff businesses remotely, with visits when they help. Cardiff combines a large public sector with professional services, fintech, a creative industry and a compound semiconductor cluster, which makes for very different buyers.
What the Cardiff market looks like.
Around three hundred and eighty thousand people live in Cardiff and over twelve thousand enterprises are registered. Health and social work is the largest employer, with public administration second, so many local businesses also sell to public bodies.

Across the Severn
The fastest train from London Paddington to Cardiff Central takes about 1h 44m, so a visit to Cardiff fits easily into a working day. We are glad to come for kick-offs, bid preparation, workshops and launches.
The weeks in between
Most Cardiff engagements settle into a simple pattern. A call at the start of each month to agree priorities, written updates as work is finished, and a Friday note that sets the numbers beside the plan. Bid deadlines and board meetings go into a shared calendar so nothing we produce arrives late for the people who need it, and every file stays in a folder you control.
If you work in both English and Welsh, tell us at the start. We plan bilingual pages and campaigns from day one, with translation by a fluent writer rather than a tool, so both versions read naturally.
What we would look at first
A Cardiff firm that bids for council, health board or university contracts is reviewed by people who read every page carefully. Our first pass looks for what an evaluator would expect to find: accessibility, policies, case notes that describe the work in measurable terms, and a clear statement of who to contact. For semiconductor and fintech companies, we start instead with the technical pages, checking that specialists can find the detail they need quickly.

Questions from Cardiff.
Do you have an office in Cardiff?
No. The team works from London, and Cardiff is close enough that a visit fits into an ordinary day when one is needed.
Can you produce bilingual Welsh and English content?
Yes. We plan bilingual sites and campaigns from the start and arrange translation by a fluent Welsh writer rather than a tool, so both languages read as if written first.
We sell to the public sector. Can you help with that?
Yes. We make sure your site meets accessibility standards and clearly sets out the evidence buyers look for when they shortlist suppliers.
Can you help a screen or creative business in the city?
Yes. Production companies and studios are hired on their reel and their reputation. We make the work easy to see, credit it properly, and keep the site light enough to load fast on any connection.
