Real Estate Leads from Companies House: How to Find New Property Companies in 2026

If you sell services to property companies — whether that's accounting, insurance, mortgages, legal, or compliance — there's a pipeline of new prospects you might be overlooking entirely. Real estate is consistently the number one sector for new UK company formations, and it isn't even close.

Every working day, hundreds of new property companies are incorporated at Companies House. Each one represents a director who just made a significant financial decision and now needs a stack of professional services to support it. Here's what the data shows and how to use it.

Why so many property companies?

The sheer volume of real estate incorporations surprises most people. Property accounts for roughly 11% of all new UK company formations — more than IT, retail, construction, or professional services. In the first week of March 2026 alone, over 1,350 property companies were registered at Companies House.

The reasons are structural, not cyclical:

• Section 24 tax changes. Since the phased removal of mortgage interest relief for individual landlords (completed in 2020), incorporating a property holding company has become the most tax-efficient way to own rental property. Landlords pay Corporation Tax at 25% rather than income tax at up to 45%, and can still deduct mortgage interest as a business expense.
• Portfolio growth. Lenders increasingly require a limited company structure for portfolio landlords (those with 4+ mortgaged properties). Getting a company set up before acquiring the next property is standard practice.
• Capital gains planning. Transferring property into a company structure can offer long-term capital gains advantages, particularly for higher-rate taxpayers planning their estate.
• Professional landlords. The regulatory burden on landlords has increased significantly — EPC requirements, Renters Reform Bill compliance, licensing schemes. A company structure provides liability protection and a more professional framework.

This isn't a trend that's going away. As long as property ownership through a limited company remains tax-advantageous, the incorporation numbers will stay high.

What SIC codes identify property companies?

Companies House assigns Standard Industrial Classification (SIC) codes at incorporation. For real estate, the key codes to filter on are:

The vast majority fall under 68100 and 68209 — these are buy-to-let landlords and property investors setting up holding companies. SIC 68310 and 68320 represent estate agents and property managers, which are a different (but also valuable) audience.

If you're searching Companies House manually, you can filter by these codes. But doing it daily at scale is impractical — which is where automated data feeds come in.

Who should be targeting new property companies?

A newly incorporated property company has a predictable set of needs. If you sell any of these services, new real estate incorporations are your ideal prospect list:

Accountants and tax advisers

This is the single biggest opportunity. Every new property company needs an accountant who understands buy-to-let tax structures, Corporation Tax filings, and the interaction between personal and company finances. Many directors are first-time company owners who previously filed self-assessment as individual landlords. They need guidance on salary vs. dividend extraction, allowable expenses, and annual filing obligations. The average fee for a property company accounting package runs £600–£1,500 per year.

Mortgage brokers

Limited company buy-to-let mortgages are a specialist area. The director incorporating a property company often needs a broker who can navigate the limited company lending market — rates, lender criteria, personal guarantee requirements, and the differences between SPV (Special Purpose Vehicle) lending and trading company mortgages. This is a high-value lead: a single property purchase can generate £1,000–3,000+ in broker commission.

Insurance brokers

A company-owned property needs landlord insurance in the company's name, not the individual's. This typically includes buildings insurance, landlord liability, rent guarantee, and legal expenses cover. If the company employs anyone (even a part-time property manager), employers' liability insurance is a legal requirement. Premiums for a typical buy-to-let portfolio range from £200–800 per year — recurring annually.

Solicitors and conveyancers

Property transfers into a company structure require legal work — transfer deeds, SDLT (Stamp Duty Land Tax) considerations, and mortgage documentation. Ongoing, the company may need tenancy agreements, Section 21/Section 8 notices, and compliance documentation. Conveyancing fees for a property transfer to an SPV typically run £800–2,000.

Property compliance services

New regulations mean landlords need EPC certificates (minimum rating C from 2028 for new tenancies), gas safety certificates, electrical safety checks (EICR), smoke and CO alarm compliance, and potentially HMO licensing. Companies offering these inspection and compliance services have a clear audience in every new property incorporation.

Business banking

A separate business bank account is essential. Many property SPVs are simple structures that don't need complex banking, but they do need a current account with the ability to receive rent, pay mortgages, and handle expenses. Digital banks like Starling and Tide are popular for property companies due to low fees and simple onboarding.

The timing advantage: why speed matters

Here's the crucial insight that separates effective outreach from wasted effort: new property company directors make their service provider decisions within the first few weeks of incorporation.

Think about it from the director's perspective. They've just incorporated a company and they're about to (or have already) purchase a property through it. They need an accountant set up before the first transaction. They need insurance before exchange. They need a mortgage broker now, not in three months.

The window of opportunity is narrow:

• Week 1: Director is actively researching accountants, brokers, and solicitors. Highly receptive to outreach.
• Weeks 2-4: Most decisions are being made. Appointments booked, providers chosen.
• Month 2+: The director has usually settled on their key providers. You're now competing against an incumbent, not a blank slate.

This is why daily data matters. If you're working from a list that's a month old, most of those directors have already chosen their accountant and broker. If you reach them on day 2 or 3, you're one of the first (and possibly the only) provider they hear from.

How to find new property companies at Companies House

There are three approaches, each with trade-offs:

1. Manual search (free, slow)

You can search the Companies House advanced search and filter by incorporation date and SIC code. This is free but tedious — you'll need to search daily, export results manually, and cross-reference director details from individual company pages. At 190+ new property companies per day, this quickly becomes unmanageable.

2. Companies House API (free, technical)

The Companies House API provides programmatic access to incorporation data. You can build scripts to pull new companies by date and SIC code, then extract director names and registered addresses. This is powerful but requires developer resource and ongoing maintenance. Rate limits also apply.

3. Automated data feeds (fastest, easiest)

Services like NewCo Data do the heavy lifting — delivering daily CSV or email reports of new incorporations filtered by sector. For property companies, you'd receive a daily list with company name, number, registered address, director name(s), SIC code, and incorporation date. No API calls, no manual searching, no developer needed.

What to say when you reach out

Knowing who to contact is half the battle. The other half is making your outreach relevant. Here are principles that work specifically for new property company directors:

• Reference the incorporation directly. "I noticed you recently incorporated [Company Name] — congratulations" immediately shows you've done your homework and aren't sending a generic blast.
• Lead with their problem, not your service. "Setting up a property company's tax structure correctly from day one can save thousands over the first few years" is more compelling than "We offer accountancy services."
• Be specific to property. Generic business services messaging won't cut it. Mention buy-to-let tax structures, Section 24, SPV mortgages, or landlord insurance specifically. They need to know you understand their world.
• Keep it short. Directors incorporating property companies are often doing this alongside a full-time job. A 3-sentence email with a clear value proposition and a simple call to action outperforms a long sales letter every time.
• Offer something useful. A free landlord tax guide, a buy-to-let structure comparison, or a 15-minute consultation call gives them a reason to respond even if they're not ready to buy today.

The numbers: what this pipeline looks like

Let's put this in perspective with real numbers from our March 2026 data:

That's roughly 48,000 new property companies per year, each needing an accountant, insurance, likely a mortgage broker, and a solicitor. If you're a property-focused service provider and you're not tapping into this pipeline, your competitors almost certainly are.

Even with conservative conversion rates — say 2-3% response rate on well-targeted outreach — that's 80-120 new clients per month from a single data source. For a specialist property accountant charging £1,000/year, that's £80,000-£120,000 in recurring annual revenue from one channel.
