How Web Design Agencies Automate Lead Generation in the UK (Full Playbook)

Around 1 in 3 UK small-business websites fails basic checks: no mobile layout, no HTTPS, a single page. The firms behind them are trading, taking work, and quietly losing the rest to competitors with credible sites. For a web design agency, that is not a market gap. That is a queue.

The problem has never been whether those businesses exist. It is that finding them by hand, one Companies House page and one squint at a site at a time, costs more than the project is worth. This playbook automates the whole thing, from the public record to the reply, so the queue works itself.

Step 1: describe the customer once

In Leadistry, setup is a two-minute chat. You say who you build for in plain words, the assistant reads your website, asks two or three questions, and shows you real sample companies before anything is charged. That sets up an agent. For web design prospects it looks like this:

• SIC codes: pick the trades and sectors you build for. Plumbers, electricians, cafes, landscapers, clinics, whatever your portfolio already speaks to. Our SIC code guide maps plain-English industries to codes, or just say "plumbers" and let the assistant pick the codes.
• Area: your town, city or region. Local matters in this niche, "we're based in Leeds too" is still the strongest opening line a small business hears.
• The website grade: the part that does the actual magic. We fetch every verified company website and grade the HTML itself (mobile layout, HTTPS, page count, copyright staleness, legacy builders) as modern, dated or poor. Ask for dated or poor and every match needs what you build. Full method in how to find UK businesses with no website.
• New companies: firms registered in the last 12 months are still deciding what the business looks like, including what its website should be. Established firms on a site nobody has touched for years are a different, also valid pitch.

Step 2: let it run every morning

You do not re-run anything. The agent looks all day and puts new matching firms on your Feed, each with its first email written. When you want a bigger batch for a specific push, "Find more now" on the agent's page runs a search on the spot, and tells you what it costs first. More on the rhythm in daily, weekly or monthly. Worth watching alongside it: companies that just changed their name, because a rebrand almost always needs a new site; see the rebrand signal hiding in the public record.

Step 3: get to a named person

A lead you cannot contact is a row in a spreadsheet. Each delivered company comes with its website, an email address that belongs to the company, and the director's name when the public record has it, plus LinkedIn, Facebook and Instagram pages when we can confirm they are theirs, at no extra cost. You only pay for delivered leads, anything we cannot complete never counts against your allowance, and a lead whose first email bounces is credited back. All of it sits on one Leads screen.

Step 4: the short sequence that fits this niche

You do not need a five-touch enterprise cadence to sell a website to a plumber. You need one good email and a short chaser:

Email one, the intro. Short, local, specific: you noticed their site does not work on a phone, here is what you build for businesses like theirs, here is one relevant example. The first line is written for each company from its own dated reason. The rest comes from your Template, set up once: the AI writes each part from your brief, or you give it your exact words.

The chasers. Two short follow-ups go out in the same thread, on day 4 and day 9 by default. Each is written for that company and adds something new rather than repeating the first email. Both days are adjustable, and follow-ups can be switched off. People are busy, not uninterested, and how many follow-ups to send explains why two is enough.

Set the email up once and stop rewriting it per prospect. If a draft is not right, click the line and change it, or ask the assistant to make it shorter or plainer, for this email or every email.

Step 5: approve it in the Feed

This is where the playbook becomes a routine. The Feed strings it together: each morning's new companies arrive as cards, already checked, each one the email itself, written from the dated reason and greeting the director by name when the public record has it. You approve, change or skip. Approved emails go from your own Google or Microsoft mailbox, the follow-ups come back to the Feed for a quick approve when they are due (or go by themselves if Autopilot is on), and everything to that company stops the moment someone replies. Replies can also go straight to your CRM or a Slack channel over webhook or Zapier.

You can add another agent by telling the assistant on the Agents page, in one sentence, something like "local trades in Leeds whose website needs rebuilding". Nothing sends until you say so. Autopilot is off by default, and even switched on it never answers a reply. Approve each email or send automatically covers when to switch it on.

What the numbers look like

A realistic weekly rhythm for a solo agency on the Growth plan (900 leads a month):

• ~50 fresh poor-website companies approved per week, a sending pace your mailbox can sustain, well inside the allowance
• An email that belongs to the company on every lead, and the lead credited back if its first email bounces
• Sends start at 5 a day and climb, paced by mailbox warm-up, so deliverability holds
• Replies land in your own inbox and on the Desk, with an answer drafted for you to send

If two conversations a week turn into one project a month, the subscription pays for itself somewhere around the first invoice's deposit.

Why this beats buying a list

Purchased lists decay, overlap with every other buyer, and carry GDPR risk you cannot audit. This playbook pulls from the live public record at Companies House, enriches from public sources with a documented lawful basis (see our GDPR guide), honours suppression lists automatically, and refreshes itself every morning. The leads are yours alone, we never resell your search results.
