Wales subcontractors: be the firm buyers in Wales shortlist first.
Across Wales the people buying subcontract packages are the quantity surveyors and procurement teams at Willmott Dixon, Kier, Morgan Sindall, Bouygues UK, Andrew Scott, Jehu, Knox and Wells and Wynne Construction, the developers and housing associations behind the region’s programmes, and the public bodies buying through SEWSCAP, the North Wales Construction Partnership and the Welsh Government frameworks. Almost all of them now start online, and a growing share ask an AI assistant to shortlist a subcontractor by trade and region before they issue a tender. Public sector work in Wales goes through Sell2Wales and the regional frameworks, both of which ask for accreditations, community benefits and Welsh-language capability that a site should state plainly. We build the website that gets you into that shortlist.
A lot of work, and a lot of subcontractors chasing the same searches.
The programmes driving demand in Wales right now include the Cardiff Bay and central Cardiff pipeline, the Velindre cancer centre, the Swansea Bay City Deal projects, the Anglesey and Celtic freeports, the 21st Century Schools and Sustainable Communities for Learning programme, and the housing programmes built to the Welsh Housing Quality Standard. Every one of them is bought through main contractors and frameworks that check the same four things before they shortlist a subcontractor.
Found
A QS at one of the region’s main contractors searches for your trade plus Wales or the nearest city and, increasingly, asks ChatGPT or Google AI who to invite. A trade page and a Wales page with real substance, and a Google Business Profile that matches, are what put you in that list.
Verified
The main contractors here run supply chain registers and the public bodies buy through SEWSCAP, the North Wales Construction Partnership and the Welsh Government frameworks. Both check SSIP accreditation, Constructionline level, ISO certificates and insurance limits. If your site shows them as logos there is nothing to verify, and the enquiry goes to a firm whose certificates are written out.
Evidenced
Quality scoring on a Wales tender asks for projects like theirs: sector, value band, programme and the main contractor served. Case studies written the way a PQQ asks for them, a downloadable capability statement and your H&S figures are what move you from the long list to the shortlist.
Contacted
When the invitation comes it is a QS with a tender pack and a deadline. A named tender contact with a direct email and phone, a stated response time and a route for drawings on every page is the difference between a priced return and a missed one.

Built around the contractors, programmes and frameworks that are actually here.
A regional page is only worth having if it says something a QS in Wales would recognise. These are the things we write into every Wales site, from your own projects and the buyers you want more of.
- A Wales page covering Cardiff, Swansea, Newport, Wrexham, Bangor and the Valleys, written around the packages you have delivered there and the main contractors you delivered them for.
- Your accreditations page written out and linked to the registers, with the frameworks you are on, including any of SEWSCAP, the North Wales Construction Partnership and the Welsh Government frameworks, stated by name.
- Case studies filed by sector and value band, including at least one for each of the region’s programmes you want more of.
- Your Google Business Profile, Companies House and Constructionline details matched, so the AI tools that buyers in Wales now ask have one consistent answer.
A named tender contact and a drawing route that works on a phone, because site teams in Wales phone from site, not from a desk. If you also work in neighbouring regions, each one gets its own page.

Questions about Wales subcontractor websites
Do you need to be based in Wales to build our site?
No. Everything from the first call to launch happens by phone, email and Teams, and we work with subcontractors across the UK. What matters is that the site itself is regional: a Wales page with real substance about your projects, your main contractors and the frameworks you are on, which is what we write.
Which main contractors and frameworks should the site mention?
The ones you have actually worked for or are registered with. In Wales that usually means some of Willmott Dixon, Kier, Morgan Sindall, Bouygues UK, Andrew Scott, Jehu, Knox and Wells and Wynne Construction, and public work bought through SEWSCAP, the North Wales Construction Partnership and the Welsh Government frameworks. Naming a contractor you have delivered for, with their permission, is worth more than a list of logos, and naming a framework you are on tells a procurement team you have already passed its checks.
How many of the region’s cities should have their own page?
Start with the ones where you have projects and references. For most Wales subcontractors that is two or three of Cardiff, Swansea, Newport, Wrexham, Bangor and the Valleys, and the regional page covers the rest. Thin pages for every town are what Google and the AI tools have learned to ignore.
Will AI tools really name a subcontractor by region?
Yes, and we test it every month. Ask ChatGPT or Google AI which groundworks or M&E subcontractors in Wales have worked for a Tier 1 and it names the firms whose sites give it something to verify: accreditations written out, consistent details on the registers and case studies with values. Most Wales subcontractor sites give it nothing, which is the opportunity.
What about public sector work?
In Wales public work is advertised on Sell2Wales and bought through SEWSCAP, the North Wales Construction Partnership and the Welsh Government frameworks. Their supplier checks are the same things the Tender Check scores, so a site that passes it is most of the way to a compliant PQQ. We do not write bids, but the capability statement and case studies we build are what bid writers need to hand.
Can you run Google Ads for Wales only?
Yes. Google Ads as an add-on to the monthly plan can be limited to one region and one trade, which is often how Wales subcontractors fill a gap in the order book while the organic and AI work builds. Searches for a trade plus the region are uncontested in most trades, so the clicks are cheap relative to the package value.
