How does a construction firm get named when clients ask ChatGPT?

The estates manager for a group of independent schools needs the heating replaced in two boarding houses over the summer holidays, with no room for slippage. Before she calls the firms on last year's list, she asks ChatGPT: "which M&E contractors in Surrey have experience working in occupied schools over the summer". She gets three names. Your firm did exactly that job for two schools last August, on programme. You are not mentioned.

Construction still runs on repeat clients, supply chains and frameworks. What has changed is where the first shortlist comes from when the client is new or a procurement team wants names to invite. In a 2025 survey of more than 4,000 B2B buyers, 6sense found that buying groups had already ranked their preferred suppliers before first contact in 94% of cases (6sense, November 2025). More of that early research now happens in ChatGPT, Google's AI Overviews and AI Mode, Microsoft Copilot, Gemini, Perplexity and Claude.

Most contractors' websites show a gallery captioned "Commercial project, Guildford", a list of services and a contact form. That tells an AI assistant almost nothing. This guide is for the owner of a specialist contractor, M&E firm, fit-out company or regional builder who wants to be on that shortlist.

#What do clients ask before they pick a contractor?

They ask about their project, their constraints and their risks. The people asking are estates managers, developers, housing associations, project managers and main contractors filling a package. Typical questions:

• "Which fit-out contractors in Manchester have done Cat B office fit-outs for professional firms?"
• "Who are the best M&E contractors in the South West for schools and colleges?"
• "Which fire door installers near Birmingham are third-party certified?"
• "Do I need Constructionline Gold or is CHAS enough to get on a main contractor's supply chain?"
• "Who approves building work on higher-risk buildings now?"
• "Who can replace a flat roof on a warehouse without stopping operations?"

Each names a type of work, and most name a place, a type of building or a constraint such as "occupied". An assistant answers by looking for firms whose websites and listings use the same words about real projects; "delivering quality construction services across the UK" matches none of them. Clients also research the rules before they research contractors, so a firm that explains the compliance question well is the natural one to name.

#How does ChatGPT decide which contractors to name?

It names the firms it can place with confidence, using four kinds of evidence:

• A specialism in plain words. "Mechanical and electrical services for schools, colleges and care homes" can be matched. "Building services solutions" cannot.
• A region. Where you are based and the counties or cities you cover.
• Recent, written-up projects. The type of building, the client type, the location, the scope and the outcome.
• Checks that agree. Accreditations, trade bodies, Companies House, your Google Business Profile and reviews that say the same as your website.

Assistants look for agreement. If Companies House lists one name, your website a shortened trading name and Constructionline an address you left three years ago, the assistant has three versions of you to reconcile. Size is not the deciding factor: a twenty-person specialist with thirty well-written project pages can be named ahead of a national contractor.

#Why do project pages matter more than your homepage?

Project pages are the evidence: where an assistant learns what you build, for whom and where, and what a project manager reads before inviting you to tender. Most contractors have the raw material in their photo library and tender submissions.

A good project page covers the building and client type ("a 1960s secondary school, occupied during term, for a multi-academy trust"), the location, the scope and a value band if the client agrees, what made it hard, what you did about it and the outcome, and the certifications that applied, with a short client quote given with permission. When we rebuilt arum's website, "Each of the 12 case studies leads with a number, and each of the nine sector pages names the regulation in play." The same discipline works for a contractor: lead with the programme, the size or the saving, and name the rules the job had to meet.

Assistants read text, and get little from an uncaptioned photo or a brochure saved as an image. The main AI crawlers fetch pages but do not run JavaScript (Vercel, December 2024), so put the words in the page itself and link every project page normally. Our note on how AI crawlers read your website explains more.

#Which accreditations and schemes do clients check?

The ones your clients' procurement teams check. Each listing should use the same company name, address and description as your website.

The schemes that let installers sign off their own work under the Building Regulations are now called self-certification schemes, and the government says scheme operators must keep a public register of every certified business (GOV.UK, July 2026). Check your entry is current, because it is the record an assistant can find. Main contractors increasingly ask for Build UK's Common Assessment Standard as well as SSIP; the questions below cover which certificate to hold.

#How should you write about cost, compliance and programme?

Explain what drives cost, how you handle the rules and how you keep a job on programme, without publishing anything you would price in a tender.

Cost. You do not need a price list. A client asking what a Cat A office fit-out costs per square foot in Manchester wants to know what makes it cost more or less: the state of existing services, working hours, access and lead times on plant. A page that explains those factors is quotable. If you give ranges from your own projects, date them and state the assumptions; tender pricing itself is best kept off the site.

Compliance (checked 24 September 2026). Clients are nervous about the rules, and three facts have moved:

• The Building Safety Regulator is still the building control authority for higher-risk buildings, but on 27 January 2026 it left the HSE to become a standalone body under the Ministry of Housing, Communities and Local Government (GOV.UK, January 2026). Applications for higher-risk building work still go to the regulator, not to local authority or private building control.
• In England, the current Part L guidance is Approved Document L, 2021 edition incorporating 2023 amendments. The Future Homes and Buildings Standards were published on 24 March 2026, and the amending regulations come into force on 24 March 2027, or 24 September 2027 for higher-risk building work, with transitional arrangements for work already notified (GOV.UK, March 2026).
• CDM 2015 still requires a principal designer to plan, manage and coordinate health and safety before construction on any project with more than one contractor (HSE). The Building Regulations have a separate principal designer role, which our guide for architecture practices explains.

Date these pages and review them, because a stale compliance page does more harm than none.

Programme and disruption. Schools, surgeries and warehouses ask whether you can work while they keep running. Pages on how you phase work in occupied buildings show you have done it before.

#How narrow should you go on specialism and region?

Narrower than feels comfortable. A firm that is clearly the specialist in one or two types of work in one region is named far more often than one that claims everything everywhere, so state your area and back it with projects there. Avoid dozens of near-identical town pages with the name swapped, which search engines and assistants treat as thin, as our article on why thin pages get ignored explains.

#How do you tell whether it is working?

Pages and listings can show within weeks in assistants that search the web live, such as ChatGPT search, Perplexity, Copilot and Google's AI features. Answers drawn from a model's own memory change only when it is retrained, which takes months. Track a fixed list of 20 to 50 questions your best clients would ask, each run several times a month in a clean session, and count a win only when it repeats. Then ask "how did you hear about us" on every enquiry and count invitations to tender from new clients.

#What to do this month

1. Fix your listings. Match your company name, address and description across Companies House, Constructionline, your SSIP scheme, your self-certification scheme register, Google Business Profile and your website.
2. Write an accreditations page. List every scheme, standard and trade body in full, with the level you hold and a link to each listing.
3. Write up ten projects. Pick recent jobs in the work you want more of and publish a short page for each.
4. Date your compliance pages. Update anything on the Building Safety Regulator or Part L and add a "last checked" date.
5. Decide what you lead with. Agree one or two specialisms and a region, and rewrite your homepage opening to say so.

#Frequently asked questions

#Our work comes from repeat clients and main contractors. Does this matter for us?

Yes, though less urgently than for a firm chasing new clients. Main contractors and project managers use assistants to check firms they have been given, and a firm that looks thin online can lose out at that stage even when the introduction came through a relationship.

#Can we name clients and show project values?

Only with permission, which many clients give at handover. Otherwise, describe the client type and building instead, such as "a regional housing association" or "a Grade II listed office in York", and give a value band rather than an exact figure. The assistants need specifics about the work, not necessarily the client's name.

#Will a national contractor always be named ahead of us?

No. National firms tend to be named for broad questions, but most client questions are narrow: a type of work, a building, a place and a constraint. A regional specialist with clear evidence for that combination can be the closer match.

#What is the Common Assessment Standard, and do subcontractors need it?

It is Build UK's single prequalification standard for construction supply chains, delivered by seven recognised assessment bodies, including Achilles, Constructionline, SMAS Worksafe and Veriforce CHAS, at a desktop or a site-based level, with a building safety section (Build UK, July 2026). Build UK says a growing list of contractors and clients accept it. If the main contractors you want to work for use it, you need it; if they ask only for SSIP, that may be enough for now.

#Do I need Constructionline Gold, or is CHAS enough?

It depends on what the main contractor asks for, so ask them. Every Constructionline level includes SSIP health and safety, Gold is the level that meets the Common Assessment Standard, and Platinum adds an on-site audit (Constructionline, September 2026). CHAS can also certify to the standard. Find out which certificate and level each main contractor accepts, then say plainly on your accreditations page which one you hold.

The contractors who get named are rarely the biggest. They are the ones whose work is written down where clients and assistants can read it. If your website is still a gallery and a contact form, our Website That Sells service turns your projects and accreditations into pages that bring enquiries in.
