London subcontractors: be the firm buyers in London shortlist first.
Across London the people buying subcontract packages are the quantity surveyors and procurement teams at Mace, Multiplex, Lendlease, Skanska, Laing O’Rourke, Sir Robert McAlpine, Wates, Morgan Sindall, Bouygues UK, McLaren and Ardmore, the developers and housing associations behind the region’s programmes, and the public bodies buying through LHC, Pagabo, SCAPE, Fusion21 and the GLA and borough 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. Competition here is national: a QS in London searches for a trade and a borough and gets subcontractors from four counties, so the site has to prove you can mobilise inside the M25 and work under ULEZ, section 61 and logistics constraints. 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 London right now include Old Oak Common and the Euston HS2 site, Canada Water, the Olympic Park and Stratford, Battersea and Nine Elms, Silvertown, the Thames Tideway completion works, the NHS estates, and the affordable housing programmes of L&Q, Peabody, Clarion and Notting Hill Genesis. 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 London or the nearest city and, increasingly, asks ChatGPT or Google AI who to invite. A trade page and a London 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 LHC, Pagabo, SCAPE, Fusion21 and the GLA and borough 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 London 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 London would recognise. These are the things we write into every London site, from your own projects and the buyers you want more of.
- A London page covering all 32 boroughs and the City, from Croydon to Enfield and Hillingdon to Bexley, 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 LHC, Pagabo, SCAPE, Fusion21 and the GLA and borough 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 London now ask have one consistent answer.
A named tender contact and a drawing route that works on a phone, because site teams in London phone from site, not from a desk. If you also work in neighbouring regions, each one gets its own page.
Questions about London subcontractor websites
Do you need to be based in London 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 London 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 London that usually means some of Mace, Multiplex, Lendlease, Skanska, Laing O’Rourke, Sir Robert McAlpine, Wates, Morgan Sindall, Bouygues UK, McLaren and Ardmore, and public work bought through LHC, Pagabo, SCAPE, Fusion21 and the GLA and borough 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 London subcontractors that is two or three of all 32 boroughs and the City, from Croydon to Enfield and Hillingdon to Bexley, 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 London 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 London subcontractor sites give it nothing, which is the opportunity.
What about public sector work?
In London public work is advertised on the London Tenders Portal and Find a Tender and bought through LHC, Pagabo, SCAPE, Fusion21 and the GLA and borough 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 London 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 London 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.
