SPV Company Name Rules: What Companies House Will and Will Not Accept

Companies House will accept almost any name for a property SPV. It refuses a name that is the same as one already on the register, that uses a sensitive word without approval, that is offensive, or that falsely implies a connection with government. Everything else, including the entirely ordinary words property, investments, holdings, estates and portfolio, is registrable. A private company limited by shares must end in Limited or Ltd, and there is no exemption from that for an SPV.

The reason naming causes so much hesitation before incorporation is that people expect it to be irreversible, and it is not. A company name is one of the cheapest things on the register to change: £20 online, no effect on the company number, the mortgages, the bank account or the contracts. That changes the sensible order of work. Get a name that clears the rules and file, rather than stalling a purchase for a week over branding you can revise for the price of a takeaway. What follows is the rule set that decides whether a name clears: the suffix, the same-as test, the too-like challenge and its 12-month deadline, the sensitive-words regime, and what it costs to change your mind afterwards. Filling in the rest of the incorporation form (the IN01, share capital, the PSC statement and identity verification) is a separate job, walked through in our guide to setting up a property investment company, with the wider company structure on the SPV company pillar.

What makes a company name valid

Three rules do most of the work.

The suffix is mandatory. A private company limited by shares must end in Limited or Ltd, or the Welsh equivalents Cyfyngedig and Cyf. The exemption people read about applies only to companies limited by guarantee whose articles restrict their objects to commerce, art, science, education, religion, charity or a profession, prohibit the payment of dividends, and require assets to pass to a similar body on winding up. A property SPV is a company limited by shares that exists to distribute profit, so the exemption never applies to it. Your SPV will end in Limited or Ltd.

The same-as rule. Companies House will not register a name that is the same as one already on the register, and same does not mean character-for-character identical. Before comparing two names it strips out a list of disregarded elements:

• The legal-form suffix itself: limited, ltd, plc, cic and the Welsh equivalents.
• Geographic and descriptive additions such as UK, Great Britain, England, Wales, Scotland, Northern Ireland and similar.
• Connectors and common additions: "&", "&co", "and company", "co", "company", "holdings", "group", "services", "international" and the definite article "the". These words carry no sensitive-words restriction, so you are free to use them, but they are disregarded when Companies House compares two names under Schedule 3 to SI 2015/17, which means bolting "Holdings" or "Group" onto a name does not clear a collision.
• Punctuation, spaces and certain symbols.

It also treats certain characters as equivalent: an accented letter matches its unaccented form, and a numeral matches the word ("2" is the same as "TWO").

The practical consequence catches people out. Suppose Oakridge Property Investments Ltd is already registered and you apply for the same name. The application is refused. Your instinct is to add a word, so you try Oakridge Property Investments UK Ltd. That is refused too, because UK is a disregarded element: strip it and the suffix out of both names and you are left with OAKRIDGEPROPERTYINVESTMENTS on each side. The same is true of Oakridge Property Investments & Co Limited, Oakridge Property Investments (UK) Ltd and Oakridge-Property-Investments Ltd. To clear the rule you have to change a word that Companies House actually reads: Oakridge Residential Investments Ltd, Oakridge Property Assets Ltd or Oakridge Property 2 Ltd all work, because the differing word survives the stripping.

The prohibitions. A name is refused if its use would constitute an offence, if it is offensive, if it falsely suggests a connection with UK government, a devolved administration, a local authority or a specified public authority, or if it contains computer code. These rarely trouble a property SPV, but the government-connection rule is worth remembering if you were considering something like National Housing or Crown Estates in your name.

Check a candidate name against the Companies House name availability checker before you file. It applies the same-as test for you, which is faster than reasoning about disregarded elements yourself.

The too-like rule and its 12-month window

Passing the same-as test at registration is not the end of the matter. There is a second, separate objection route. An existing company can complain that your name is too like theirs, and that test is much wider than same-as: it catches names that differ only by a few characters, signs or punctuation, and names that simply look or sound similar. If the complaint succeeds, the Secretary of State can direct your company to change its name.

Two features of this rule matter to a landlord.

First, it is time-limited. A direction to change a name on too-like grounds must be given within 12 months of the company's registration. After that year passes unchallenged, the name is settled and no one can force a change on that ground. This is genuinely reassuring for anyone worried that a portfolio of SPVs carries an open-ended naming risk. It does not.

Second, the things people assume will save them do not feature. Holding a trademark is expressly not relevant to a too-like assessment, and neither is operating in a different part of the country. A Manchester letting company and a Cornwall letting company with near-identical names are as exposed to each other as two on the same street.

The rule cuts both ways. If someone registers a name uncomfortably close to your SPV's, you have a defined route to object and a deadline to use it. Diarise the anniversary of your own registration if you have chosen something close to an incumbent.

Sensitive words and expressions

Some words need prior approval before they can appear in a company name, and a few need the written view of a named regulator submitted to Companies House alongside the application. The live lists are the annexes to the gov.uk incorporation and names guidance: the annexes set out words requiring approval, the bodies you must ask, and words regulated under other legislation. Broadly, they cover terms implying pre-eminence or national or governmental status, terms implying a regulated activity or professional qualification, and terms protected by specific statutes.

This is not a paperwork risk to shrug at. Using a sensitive word without the required approval is a criminal offence carrying a fine, so if a candidate name contains anything that sounds official, professional or regulated, check it against the annexes rather than assuming.

For an ordinary property SPV the answer is almost always that nothing in the name is sensitive. Property, investments, investment, holdings, residential, lettings, portfolio, estates, assets, homes and land are descriptive commercial words, not protected ones, and they appear in the registered names of thousands of buy-to-let companies. You do not need permission for any of them. Personal surnames, place names that are not claiming official status, and invented words are equally unproblematic.

One field that is not affected either way: your SIC code. Your company name and your SIC code are unrelated entries on the register, and nothing in the name has to match or reflect the code you choose. A company called Oakridge Property Ltd can register any code, and a company with no property word in its name can register any of the property SIC codes. Which code to use is a separate, and commercially more important, decision, covered in our guide to the SIC code for an SPV property company.

Choosing a name for a property SPV

Once the legal filter is passed, the remaining decisions are practical.

Distinctive first word, descriptive second. The structure that clears the same-as rule most reliably is a distinctive word (a place, a surname, a coined word) followed by a descriptive one. Oakridge Property Ltd, Salter Residential Ltd, Kelvinside Estates Ltd. The distinctive element does the work of separating you from the register; the descriptive element tells a lender, a solicitor or a tenant what the company does.

Naming the SPV after yourself. It is permitted and it is common. The upside is distinctiveness and credibility. The downside is disclosure: the registered name follows the company onto Land Registry title entries, tenancy agreements, correspondence and the public register, so a personal-name SPV visibly links you to every property it holds. Some landlords are content with that, others deliberately choose a neutral name.

Portfolio and numbered SPVs. Landlords running several companies, often one per lender, per property type or per financing round, usually adopt a numbered series: Oakridge Property 1 Ltd, Oakridge Property 2 Ltd, and so on. This is fine under the same-as rule, because the numeral is a word Companies House reads (remembering that "2" and "TWO" are treated as the same, so you cannot have both). The series keeps bank statements, mortgage offers and accounting records legible when you are running five companies at once, which matters more than it sounds when the completion statements start arriving.

Trading names. If the registered name is plain and you want to market under something better, you can. A company may trade under a business name different from its registered name. The trading-disclosure rules still apply: the registered name must be displayed at the registered office and on business letters, order forms, invoices and the website. A trading name carries no legal protection of its own, so it is a presentation tool, not an alternative to choosing the registered name carefully.

Can I call my company Property Investments Ltd?

Legally, there is nothing wrong with it. None of those words is sensitive, none needs approval, and the name breaks no prohibition.

In practice you will probably not get it, and you would not want it if you did. A name that generic is very likely to be the same as an existing registration once the disregarded elements come out, and every obvious variation on it (adding UK, adding &Co, adding punctuation, adding Ltd differently) fails for exactly the same reason. Even if you cleared the register, the name is indistinguishable from dozens of near-identical companies, which makes life harder every time a lender, a conveyancer or your own bank has to identify the right entity from a company search.

Genericness also leaves you exposed at the margins of the too-like rule during that first 12 months, in both directions. The fix costs nothing: put a distinctive word in front. Oakridge Property Investments Ltd clears the register, is searchable, and reads exactly as professionally.

Changing a company name later

A company changes its name by special resolution of its members, or by any other means provided for in its articles. It is not a board resolution, despite how often that phrase appears online. In a single-director, single-shareholder SPV the same person signs in both capacities, but the resolution should be recorded correctly as a members' resolution.

Where the special-resolution route is used, a copy of the resolution must be delivered to Companies House within 15 days of being passed. Two timing points follow from that. The change takes effect when Companies House registers it, not when the members pass the resolution, and Companies House then issues a certificate on change of name. Do not start signing in the new name in the gap between the two.

The fees, current on the gov.uk Companies House fees page updated 2 July 2026:

Route	Fee
Change of name, online	£20
Change of name, software filing	£20
Change of name, paper (form NM01)	£30
Same-day change of name (online or software only)	£85

The fee is per change and per company, so renaming four portfolio SPVs online costs £80. For context, incorporating a company in the first place costs £100 online or by software and £124 on paper, so the name is set as part of a filing you are already paying for, and revising it later is a fifth of that. Those and the wider set-up numbers are broken down in our SPV company formation cost guide.

One distinction worth keeping straight: changing your company name and changing your SIC code are different filings on different mechanisms. The name change is a special resolution plus notification (or form NM01 on paper). The SIC code is updated on the confirmation statement. They are not done together, they are not the same fee, and doing one does not update the other. If it is the code you need to correct, our guide to changing a SIC code at Companies House covers that filing on its own.

What a name change does not affect

The anxiety that stops landlords renaming an SPV is the fear that the change ripples through everything else. It does not, because the company is the same legal person before and after. Its registration number never changes, and the number, not the name, is what the register, lenders and HMRC actually key on.

So the following all continue unbroken:

• Mortgages and charges. Existing facilities stay in place. The lender updates its records and the charge details on notification.
• The bank account. The account continues; the bank changes the name on it once you supply the certificate on change of name.
• Contracts, leases and tenancies. Existing agreements remain binding on the company. Notify counterparties so future correspondence matches, but the agreements do not need re-signing.
• VAT and corporation tax registrations. Registrations follow the company, not the name. Notify HMRC so its records match the register.
• Land Registry titles. Ownership is unaffected; the proprietor's name on the title is updated on application with evidence of the change.
• The original certificate of incorporation. It stays valid. The certificate on change of name sits alongside it rather than replacing it.

The work in a rename is administrative notification, not legal reconstruction. That is the reason the naming decision does not deserve to hold up an incorporation: choose something that clears the rules, file it, and revisit the branding when the purchase is done.

One boundary worth stating plainly, because Companies House acceptance is routinely misread as a clearance. Getting a name onto the register proves only that no identical company name already exists. It says nothing about trademarks. Someone else's registered trademark can still be infringed by a company name that Companies House was perfectly happy to register, and that dispute is settled in the courts, not on the register. Before you put a name on signage, a domain and letterheads, run it through the UK trademark search. For a plain descriptive SPV name this is a two-minute check that comes back clean; for anything that reads as a consumer brand, it is worth doing properly.
