Legal & Law Firms Web Developers in Cardiff (April 2026)

Law firm websites in Cardiff face compliance requirements that most web agencies have never read: the Solicitors Regulation Authority's Transparency Rules (effective 2018, updated 2022) mandate that regulated firms publish indicative prices for six listed service areas, clearly describe the complaint process, and display a link to the Legal Ombudsman. Firms that ignore these requirements risk SRA regulatory action-and most Cardiff law firm websites we have reviewed fail at least two of these requirements because the agency that built them approached it as a brochure, not a regulated communication.

Buyer's Checklist

What to look for in a legal & law firms web developer in Cardiff

These are the questions and checks that separate legal & law firms specialists from general web agencies who will list your sector on their homepage after you sign.

SRA Transparency Rules compliance: price indication for all six mandated service areas displayed clearly-not hidden in a PDF or buried in footer text

Solicitor/barrister profile pages with SRA registration numbers, call to the bar dates, and specialisation areas-supports E-E-A-T signals and client trust

Inquiry form design with clear matter type classification: routing different inquiry types to the correct fee earner is a conversion and compliance issue

Legal Ombudsman and SRA badges displayed correctly-check placement and link accuracy; incorrect or outdated badge display is a common SRA audit finding

Content E-E-A-T: legal article authors must be named qualified fee earners with listed specialisms-ghost-written 'thought leadership' with no named author scores poorly with Google's legal YMYL classifier

Platforms & Tech Stack

Which platform for legal & law firms in Cardiff?

Custom WordPress

The most common stack for Cardiff law firms. Attorney/solicitor profile custom post types, practice area taxonomy, and case study pages managed by practice managers without developer involvement. Must be custom-themed for SRA compliance display.

Next.js + Contentful

Preferred for multi-practice firms, chambers, and international law firm offices in Cardiff requiring performance-optimised practice area pages, multi-author article publishing, and CRM integration.

Clio Grow / Lawmatics embed

Legal CRM intake forms. These embed into any website and route inquiry data directly into the firm's matter management system. Should be used by any Cardiff firm with more than 4 fee earners.

LexBlog (barrister chambers)

A specialist legal blogging platform used by UK barrister chambers. Provides SRA-aware template structures and a content community. Consider for chambers with high blog publishing volume.
