A practical guide for UK business owners on using Companies House incorporation data to find, qualify and convert new business leads before competitors even notice them.
A brand-new limited company is the closest thing to a buying signal you can get in B2B. The director has just committed money, time and reputation to a venture. In the first 90 days they will buy insurance, accounting, a bank account, a website, possibly premises, equipment, vehicles, telecoms, and often legal advice. Every one of those is a purchase decision made by one or two people who are, right now, actively looking.
That is the difference between a cold list and a warm one. A company incorporated three years ago has already chosen its accountant and its insurer. A company incorporated nine days ago has not. Companies House publishes incorporation data daily, which means the buying window is visible to anyone prepared to work it systematically rather than occasionally.
The trap is treating incorporation data as a mailing list. It is not. It is a timing signal. The businesses that win from it are the ones who build a repeatable process around speed, relevance and follow-up, not the ones who buy the biggest file.
The public register is genuinely useful, but it is raw material. Understanding what each field tells you stops you wasting calls on the wrong prospects.
| Field | What it tells you | How to use it |
|---|---|---|
| Company name | Often reveals sector or trade (e.g. '...Plumbing Ltd') | Segment your list by trade keywords before calling |
| Incorporation date | Exactly how fresh the lead is | Prioritise anything under 30 days old |
| Registered office | Region, and sometimes an accountant's or virtual address | Territory targeting; flag virtual offices for lower priority |
| Director name and month of birth | Decision-maker identity and rough age band | Personalise your opening line; use full name |
| SIC codes | Stated business activity | Route to the right service; treat as indicative, not gospel |
| Nature of business | Sometimes a short description | Read it before dialling, not during the call |
What it does not give you is a phone number, an email, a budget, a pain point or any indication that the director wants to hear from you. That gap is exactly where lead providers add value: they filter the register by sector and region, enrich contact details, and remove the obvious dead ends such as dormant shells and bulk-incorporation vehicles.
One caution worth stating plainly: a registered office is frequently an accountant's address. That is not a reason to discard the lead; it is a reason to ask a better opening question rather than assuming the address is where the business operates.
Raw incorporation volume in the UK is high, so an unfiltered list will bury you. Apply these filters in order and your call-to-conversation rate will improve immediately.
For example, a commercial cleaning firm should filter to new companies with premises-relevant SIC codes in its own city, not to every incorporation in the country. A tender consultancy should filter to new companies in construction and facilities management, where public sector work is realistic. A probate solicitor works a different trigger entirely, but the discipline is identical: narrow, then call.
Speed is the whole game. A director who registers a company on Monday is making supplier decisions all week. If your first contact lands on day nine, you are competing with whoever called on day two. Build a routine that makes same-day or next-morning contact the default, not the ambition.
Two calls and an email inside the first week is not aggressive; it is normal commercial behaviour and most competitors are not doing it. The mistake is a single call, no voicemail, and a shrug. Directors of new companies are busy and often out of the office, so persistence with relevance beats volume without it.
A new director is not defensive about being new; they are usually proud of it. Use that. A weak opening is 'I'm calling about your new business.' A strong opening proves you know something specific and offers something useful.
Notice what these do not do: they do not claim exclusivity, they do not pretend to know more than the public register shows, and they do not launch into a feature list. They establish relevance in one sentence and hand the conversation to the director.
The same principle applies across sectors. A removal company talking to a new company about an office move should reference premises, not house moves. An accountant should reference the first-year filing deadline, not generic tax savings. Specificity is the whole advantage of fresh incorporation data, so use it.
Buying filtered, enriched new business leads saves research hours and gives you a consistent daily flow, which matters if lead generation is not your full-time job. What it does not do is make the sale. The provider can tell you a company was incorporated on Tuesday and give you a director's name and number; it cannot tell you whether that director has already signed with a competitor.
So treat purchased leads as a starting point for a conversation, never as a guaranteed opportunity, and never describe them as exclusive. The register is public, which means the same company may appear on several providers' lists. Your defence is not exclusivity; it is being faster, more relevant and better prepared than the next caller.
Do your own qualifying on the call: confirm trading status, confirm the decision-maker, confirm the need and the timeline. Record what you learn and feed it back into your segmentation. Over a few months you will learn which SIC codes, regions and company sizes convert, and your list will get sharper each time.
Most businesses that fail with incorporation leads are not measuring anything, so they cannot tell whether the list is bad or their follow-up is. Track a small number of numbers weekly: leads received, first contacts made within 48 hours, conversations held, quotes issued, and deals closed. If first-contact speed is poor, fix the process before blaming the data.
Expect modest but real conversion. Fresh incorporations are early-stage buyers, so many will not need you yet. That is why the 30-day re-contact matters: a company that ignores you in week one may buy in month three, and the record costs you nothing to keep. The compounding effect of a daily habit, worked properly for a year, is a pipeline most competitors never build.
The final point is simple. The register is free, public and updated daily. The edge is not access to the data; it is the discipline of acting on it within 48 hours, with a relevant opening line and a follow-up that does not stop after one attempt.

The practical value is in acting within the first 30 days, while the director is still setting up suppliers, banking and premises and has not yet locked in a provider.
No. The raw register gives you a name, number, registered address and director details, but nothing about sector, size, intent or contactability. A lead provider filters and enriches that data so you get a callable, relevant prospect rather than a CSV of 400,000 rows.
Waiting. Most businesses sit on a lead list for a week or more before the first call. Fresh incorporations go stale fast because the director is actively buying services right now and will take the first credible call. Build a same-day or next-morning call routine.
Yes, but the angle differs. A removal firm can use new incorporations to spot office relocations and fit-outs; a solicitor can target directors who need shareholder agreements, employment contracts or commercial lease reviews in their first quarter. Match your opening line to the trigger.
