Regulated vs Unregulated Property Finance: What the Difference Means for You

Regulated vs Unregulated Property Finance at a Glance

We find the regulated or unregulated status of your property finance is determined by the borrower and the intended use of the security — not by your choice of lender. You can’t opt in or out of FCA regulation by selecting a different product.

Regulated property finance applies when:

• The security is a property you or an immediate family member occupies or intends to occupy as a main residence
• The borrower is an individual (not a limited company or business)
• At least 40% of a mixed-use property is used as a dwelling by you or a qualifying family member

Unregulated property finance applies when:

• The security is a commercial property
• The borrower is a limited company
• The security is residential but you’re buying to let or invest, not to live in
• The property is being developed or refurbished for resale, not occupation

What Makes Property Finance Regulated

We see property finance as regulated when it’s secured on a property that is, or will be, your home — or the home of an immediate family member. The FCA applies its Mortgage Conduct of Business (MCOB) rules to these loans, regardless of the product label.

We’d note that your immediate family includes a spouse, civil partner, parent, child, sibling or grandparent. If any of those people will occupy at least 40% of the security property, your loan sits inside FCA regulation.

The 40% Dwelling Threshold

We see that mixed-use properties — a flat above a shop — are regulated if the dwelling portion reaches 40% or more. We find this threshold catches many borrowers by surprise. If you’re buying a property with a residential element, confirming the dwelling proportion before applying avoids a mis-structured loan.

We find that below 40% residential use, the loan can fall outside FCA scope. Above it, MCOB applies in full — neither you nor the lender can contract out of this.

What MCOB Requires in Practice

From what we’ve seen, for regulated property finance, the lender must be FCA-authorised specifically for regulated mortgage business. Your broker must also be FCA-authorised or operate as an appointed representative of an authorised firm.

MCOB imposes full affordability assessment requirements, clear disclosure of costs and risks, and suitability checks. The lender can’t simply assess the asset and advance — they must consider your wider financial position and whether the product is appropriate for your circumstances.

What Makes Property Finance Unregulated

We classify property finance as outside FCA regulation when the borrower is a business or the security is an investment or commercial property. The most common scenarios are buy-to-let purchases, commercial property transactions, and limited company borrowing — all of which are unregulated regardless of the lender you use.

We’d stress that unregulated lending isn’t lawless. Lenders still operate under general commercial law, anti-money laundering obligations, and responsible lending principles. The specific consumer protections of MCOB simply don’t apply, which means the process is faster and criteria are more flexible — but you carry more of the risk.

Limited Company Borrowing

We note that if you borrow through a limited company, the loan is automatically unregulated regardless of the property type or its intended use. The company — not you personally — is the borrower, and FCA consumer protections apply to individuals, not corporate entities.

We recommend confirming with your solicitor and broker whether you should borrow personally or through a company. Tax and liability considerations often drive this decision, but the regulatory implications are significant: personal borrowing on your home triggers MCOB, company borrowing does not.

Buy-to-Let and Investment Property

We find that buying residential property to let is unregulated, even though the security is a house or flat. The regulatory distinction runs through the borrower’s intended use, not the physical structure. If you won’t live there, MCOB doesn’t apply.

We look at development finance — funding a build or refurbishment for onward sale — is almost always unregulated. The product is a commercial lending decision against a project, not a consumer mortgage against your home.

Why the Regulated vs Unregulated Distinction Matters for Your Finance

We see the difference in regulatory status as having direct practical consequences for you as a borrower. The protections available, the lender pool you can access, and the speed and cost of your transaction are all shaped by which regime applies.

Consumer Protections

We highlight that if your loan is regulated, you can escalate unresolved complaints to the Financial Ombudsman Service. The FOS can award compensation and direct the lender to remedy the situation. This route doesn’t exist for unregulated borrowers.

We note that the Financial Services Compensation Scheme also provides limited protections for regulated mortgage products in certain failure scenarios. We find most regulated borrowers are unaware of these protections until they need them.

Lender Eligibility and the Authorised Lender List

We find that for regulated mortgage products, you can only use lenders on the FCA Register. If a lender isn’t authorised for regulated mortgage business, they can’t legally offer your loan. You should verify any regulated lender on the FCA Register before signing.

We’ve found that unregulated lenders operate under a wider licence and don’t need specific FCA mortgage authorisation. We find this gives the unregulated market a larger active lender pool — particularly in the bridging and development finance sector.

Speed, Process and Cost

We’ve seen that regulated cases run slower. MCOB requirements mean full affordability assessment, suitability checks and heavier disclosure paperwork. For bridging, expect three to four weeks rather than one to two.

We’ve seen unregulated bridging complete in days where the valuation and legals cooperate. We find this speed differential is one reason property investors almost always use unregulated finance — not just for cheaper pricing, but because the timeline aligns with auction deadlines and development programmes.

The Professional Investor Exemption in Property Finance

We’ve found that some unregulated property finance is available under high net worth or sophisticated investor exemptions. These allow lenders to offer terms that fall outside standard consumer protections to qualifying individuals who are deemed capable of assessing the risks themselves.

The qualifying criteria are specific and set by the FCA. We recommend confirming your exemption status with your broker before relying on it. Misclassification — borrowing under an exemption you don’t actually qualify for — creates risk for both you and the lender.
