New company alerts by SIC code and postcode area

Companies House incorporation alerts filtered by SIC code and UK postcode area — built for a focused accountant review routine.

If you already know the types of businesses you want to work with and roughly where they're based, this is a simple way to keep watch without trawling Companies House yourself.

LaunchRegister checks new Companies House records each working day, filters them by SIC code and postcode area, and delivers matches daily or weekly. It is designed for accountancy practices that want a repeatable weekly outreach workflow with low noise and predictable delivery.

Who this is for

This page is for you if you're a UK accountancy practice and you:

• have a clear view of which sectors you want more of, or which you want to avoid
• focus on specific geographies (local catchment areas, regions, or remote-but-targeted areas)
• prefer email, workspace and export delivery you can hand to a team member and action consistently
• want to reduce time spent on manual searching and minimise irrelevant companies

If you're still at the "send me everything and I'll see what sticks" stage, you'll probably get more value from new company leads for accountants. This page is specifically about tightening your lead list by SIC code or postcode area.

The filters you can use

SIC codes (industry)

Companies House allows new companies to select one or more SIC 2007 codes at incorporation (often up to four). LaunchRegister can be configured to include:

• a focused list of SIC codes that represent your target industries
• a broader list, if you prefer higher volume and review manually

Postcode areas (location)

While a company's registered office postcode isn't always where the work happens, it's still a useful and reliable starting point for outreach. LaunchRegister can filter by postcode area (the first one or two letters of a UK postcode), for example:

• M (Manchester)
• B (Birmingham)
• BS (Bristol)
• SW / SE / E (London areas)

This is usually a better first-pass location filter than trying to force tight radius logic from Companies House data. It's simple and consistent.

Choosing SIC codes and what to exclude

SIC filtering is where most of the quality comes from — and also where most of the noise can creep in. Codes can be missing, overly broad, or changed later. Filtering helps, but it won't remove all the edge cases.

A sensible way to choose your SIC codes

• Start from your best existing clients. List the industries you'd happily take more of.
• Pick a small initial set. You can expand once you're confident the feed is relevant.
• Expect multiple SICs. Some companies select broad or mixed codes; don't assume perfect classification.
• Keep it reviewable. A targeted list your team can work through each week beats a huge feed nobody touches.

What to consider excluding

Rather than guessing a perfect list, it's safer to think in categories that tend to generate irrelevant results for many accountancy firms:

• Generic catch-all classifications that can cover a wide range of businesses (often low signal)
• Holding-company-style incorporations that exist for structuring rather than trading
• Company formations that look administrative (created for ownership, property SPVs, internal group changes)

You'd typically start with your preferred inclusions and then tighten the list after you've seen a week or two of real results.

How the alert workflow works

LaunchRegister is intentionally focused rather than a broad company-research database. On the schedule you choose, you receive:

• an email with your latest matched-company summary
• a narrow workspace for reviewing and recording the first approach
• XLSX and CSV exports for handing selected companies into your existing systems

You can assign the review to the team member responsible for new-business outreach, export suitable companies into your CRM or spreadsheet, and turn it into a consistent weekly task rather than a sporadic search.

Example fields you receive in the CSV

• company name
• company number
• incorporation date
• registered office address
• SIC code(s) / nature of business

This is designed to be enough to do a quick relevance check, allocate items to team members, and start compliant outreach. No enrichment, no appended personal data, and no lead scoring.

Common pitfalls and how to handle them

Too much noise

Cause: filters set too broadly at the start. Fix: start narrower than you think, then expand once you're confident the feed is actionable.

Duplicates

Cause: companies can match multiple SIC codes, and your filters might overlap. Fix: LaunchRegister dedupes results where possible; if any slip through, the CSV is structured so you can dedupe by company number.

Dormant or holding companies

Cause: some incorporations are created for structuring, property SPVs, or future use, and can look like real leads at first glance. Fix: use exclusions where appropriate, and accept that a small amount of manual judgement is normal with public incorporation data.

Registered office isn't the trading address

Cause: accountants, formation agents, and registered office services can be used. Fix: treat postcode filtering as a practical first filter, not a guarantee. Many firms still get strong results using postcode-area targeting, especially when combined with SIC.
