For trade and local-service businesses considering a new website in Cardiff
Web design for trades and local services in Cardiff: hand-coded, built to rank from day one
You run a trade or local-service business in Cardiff and your current website is not pulling its weight. This page is for you. A hand-coded Next.js website built for the conversion path your customers actually use and the search terms they actually type into Google. Pure code, no WordPress, no page builder, no marketplace theme, no 200KB of unused JavaScript.
Every Cardiff build ships with the same level of technical SEO work that this site has: semantic HTML, schema.org markup on every page type, internal linking architecture, Core Web Vitals in the green, copy that reads like a human because it was written by one. The build is the foundation, pair it with the local SEO retainer and the site launches into work that compounds month over month.
Local market context
What trades and local service businesses in {city.name} need from a hand-coded site
Cardiff’s local search market is underserved compared to comparable English cities. The local pack for trades and professional services has real gaps, which makes it one of the more cost-effective markets for proper local SEO investment in the UK. The bilingual (Welsh/English) market creates some niche opportunities for businesses serving Welsh-speaking customers.
A hand-coded site hits PageSpeed 90+ on mobile, scores in the green on Core Web Vitals, and earns its keep over 12+ months of organic ranking. The Cardiff trades, professional services, hospitality, bilingual services market rewards sites that load fast and rank for the queries their customers actually type.

What a hand-coded site does for {city.name} businesses
The deliverable
Cardiff's local market is well-contested across the trades, with the strongest competition in plumbing, electrical, and roofing. The Cardiff Bay redevelopment drives hospitality and professional services volume. A hand-coded Next.js site that hits PageSpeed 90+ on mobile is the difference between ranking in the Maps 3-pack and being invisible behind the chains.
Welsh trade regulation differs from England. The site needs to surface the appropriate Welsh certifications — Gas Safe Register (still applies), but trade-body membership differs from English equivalents. NICEIC operates in Wales too.
Cardiff customers use mobile for trades search at high rates. The Cardiff SERP rewards comprehensive schema markup. LocalBusiness, Service, FAQPage, BreadcrumbList — each type earns a different SERP feature.
Welsh-language support is a unique lever for Cardiff. A bilingual Welsh-English site (or at least a "Cymraeg" toggle) signals local commitment and earns trust in the Welsh-speaking segments of the market.
The trade mix includes a lot of Victorian and Edwardian terrace property work. High-value renovation projects reward a rank-first site with detailed service pages.
Trust and certification
Where to display your trust signals on the build
Gas Safe Register, NICEIC (Wales office), and the Cardiff BID. Each of these is a citation opportunity for Cardiff businesses, and the registration display on the homepage is schema-marked-up so Google can surface it as a knowledge-panel attribute.

Frequently asked questions
Do you work across South Wales or just Cardiff?
All of South Wales — Cardiff, Newport, the Vale of Glamorgan, Caerphilly, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, and down to Swansea.
Are there bilingual (Welsh/English) local SEO opportunities in Cardiff?
Limited but real — Cardiff Welsh is a smaller population than rural West Wales, but bilingual GBP content and bilingual service pages can be a useful differentiator for trades and professional services serving Welsh-speaking customers in the wider South Wales area.
What does it cost to work with you in Cardiff?
The Core retainer is £449-499/month — GBP management, citations, review response, and one content piece, covering Cardiff and the surrounding service area. Growth is £597-697/month if you want backlink acquisition and AI visibility tracking added. Same pricing whether you're in Cardiff or anywhere else in the UK — the work doesn't get more expensive because of where you're based.
How much does a hand-coded website cost in Cardiff?
Same as anywhere in the UK: £1,500-£5,000 one-off, fixed quote. The price depends on the number of pages, the complexity of the integrations (booking, payments, custom functionality), and how much copy and photography you can supply. Cardiff projects land at the same bands as everywhere else, what changes is the local SERP competition, which the Local SEO retainer addresses.
Do you build sites for Cardiff trades specifically?
Yes. The build process is the same regardless of city, but the conversion-path engineering is tuned to the local market. Cardiff trades (plumbers, electricians, roofers, kitchen fitters, bathroom fitters) get CTAs that match how Cardiff customers actually search and book, click-to-call for emergencies, quote-form for planned work, consultation-booking for higher-ticket services.
