Regulated vs Unregulated Bridging Finance: What’s the Difference?
Not every bridging loan is the same. Depending on who is borrowing, the property being used as security and how that property will be occupied, a bridging loan may be regulated or unregulated.
Understanding the difference is important for both brokers and borrowers. It determines which lenders can consider the application, how the loan will be assessed and which rules apply to the transaction.
Identifying the likely classification early can help avoid delays and ensure the application is directed to the right type of lender.
At Mercantile Trust, we specialise in unregulated bridging finance for property investors, landlords, limited companies and qualifying business-purpose borrowing. Customers can approach us directly or through a broker. We do not offer regulated bridging loans.
What is bridging finance?
Bridging finance is a short-term loan secured against property. It is designed to provide access to funds while a property sale, refinance or another longer-term funding solution is arranged.
It is commonly used to:
- Purchase property at auction
- Fund light refurbishment
- Secure an investment property quickly
- Raise capital against an existing property
- Complete a purchase before another property is sold
- Prevent a time-sensitive transaction from falling through
- Bridge the gap until longer-term mortgage finance is available
Unlike a traditional mortgage, bridging finance is intended to be repaid over a relatively short period.
That is why lenders place significant emphasis on the proposed exit strategy. This is the plan for repaying the loan at the end of the term.
Common exit strategies include selling a property, refinancing onto a buy-to-let mortgage or repaying the loan from another clearly evidenced source.
Whether you are applying directly or submitting a case for a client, it is important to explain both why the finance is needed and how it will be repaid.
What is regulated bridging finance?
A bridging loan is generally considered regulated when it is secured against a residential property that the borrower, or a close family member, lives in or intends to live in.
Typical examples include:
- Buying a new home before selling an existing one
- Refinancing an owner-occupied property
- Raising funds against a main residence
- Purchasing a property that will become the borrower’s home
- Securing a loan against a property occupied by a close family member
Because these loans involve someone’s home, they fall within the regulated mortgage framework and are subject to additional consumer protections.
The final classification will always depend on the individual circumstances of the application and will be assessed by the lender.
Regulated bridging finance example
A homeowner has found a new property but has not yet completed the sale of their current home.
They use bridging finance secured against their existing residence to complete the purchase. The loan will then be repaid when their current property is sold.
As the loan is secured against a property they occupy, it is likely to be regulated.
Mercantile Trust would not be able to consider this application because we only provide unregulated bridging finance.
What is unregulated bridging finance?
Unregulated bridging finance is typically used for property investment or business purposes rather than owner-occupied residential borrowing.
It may be suitable for:
- Buy-to-let purchases
- Auction acquisitions
- Property refurbishment
- Commercial or semi-commercial property
- Portfolio expansion
- Capital raising
- Limited company borrowing
- Purchasing a property to renovate and sell
- Refinancing an investment property
- Short-term business funding secured against eligible property
These loans are commonly used by property investors, landlords, developers and business owners who need a flexible, short-term funding solution.
In most unregulated cases, neither the borrower nor a close family member will live in the property being used as security.
Unregulated bridging finance example
An investor purchases a residential property at auction.
The property needs refurbishment before it will meet the requirements of a standard buy-to-let lender. The investor uses bridging finance to complete the purchase and carry out the necessary work.
Once the refurbishment is complete and the property is ready to let, the investor refinances onto a longer-term buy-to-let mortgage.
As neither the borrower nor their family will occupy the property, the bridging loan would generally be unregulated.

This provides a useful starting point, but the classification will always depend on the full circumstances of the application.
The lender will consider the borrower, the property, the intended occupation and the purpose of the loan together.
Why does the difference matter?
The distinction between regulated and unregulated bridging finance affects which lenders can consider an application.
If a regulated case is submitted to a lender that only offers unregulated finance, it may need to be declined or redirected.
This can cause delays, especially when the borrower is working towards:
- An auction completion deadline
- A time-sensitive property purchase
- An urgent refinance
- The sale of another property
- A restricted completion date
Establishing the likely classification at the beginning makes it easier to approach the right lender and set realistic expectations.
Whether you are applying directly or working with a broker, you should be ready to explain:
- Who owns the property
- Who currently occupies it
- Who will live there after completion
- Why the finance is required
- Whether the property is for investment or business use
- Whether a close family member is involved
- How the bridging loan will be repaid
Clear and accurate information helps the lender assess the application more efficiently.
Common uses of unregulated bridging finance
Unregulated bridging finance can support a wide range of property investment and business transactions.
Auction purchases
Auction purchases usually come with strict completion deadlines. Buyers may have only a few weeks to arrange the required funds after the auction.
A traditional mortgage may not be available quickly enough, particularly if the property needs work or does not initially meet the lender’s criteria.
Bridging finance can provide the funds needed to complete the purchase. The borrower may then repay the loan through a property sale or refinance onto a longer-term mortgage.
Where the property is being purchased as an investment and will not be occupied by the borrower or their family, the loan will generally be unregulated.
Property refurbishment
Some properties cannot initially be financed using a standard buy-to-let mortgage.
The property may need a new kitchen, bathroom, heating system or other repairs before it is ready to let or suitable for a longer-term lender.
A bridging loan can be used to purchase or refinance the property while the work is completed.
The borrower may then sell the property or refinance it once the work is finished.
The lender will usually want to understand:
- The proposed refurbishment
- The expected cost
- The timescale for completion
- The property’s current and expected value
- The proposed exit strategy
Buy-to-let purchases
Bridging finance can help landlords and property investors secure a buy-to-let opportunity before arranging longer-term funding.
It may be useful where:
- A quick completion is required
- The property is not currently mortgageable
- Refurbishment is needed before the property can be let
- The investor is waiting for another transaction to complete
- A buy-to-let mortgage application is still in progress
The exit may involve refinancing onto a buy-to-let mortgage once the property and borrower meet the longer-term lender’s requirements.
Capital raising
Property investors and business owners may use bridging finance to release capital from an existing property.
The funds could be used to:
- Purchase another investment property
- Complete refurbishment works
- Support short-term business cash flow
- Pay an urgent business expense
- Resolve a temporary funding gap
- Complete another time-sensitive transaction
The purpose of the funds, the property being offered as security and the repayment plan will all form part of the lender’s assessment.
Property chain situations
Bridging finance is often associated with homeowners trying to prevent a residential property chain from collapsing. Where the borrower’s home is involved, this type of borrowing may be regulated.
However, similar situations can arise in property investment.
For example, a landlord may need to complete on a new rental property before the sale of another investment property has finished.
If neither property is occupied by the borrower or a close family member, the loan may be unregulated.
The occupation and purpose of the transaction are more important than simply describing the case as chain-break finance.
Limited company borrowing
Limited companies frequently use bridging finance to purchase, refinance or improve investment property.
Common examples include:
- A special-purpose vehicle purchasing a buy-to-let property
- A property company buying at auction
- A limited company raising capital from an existing asset
- A company completing refurbishment before refinancing
- A business purchasing commercial premises
Limited company borrowing will generally be unregulated, although the full borrowing structure and property use will still need to be reviewed.
Are all buy-to-let bridging loans unregulated?
Most bridging loans used for genuine buy-to-let investment will be unregulated.
However, describing a property as buy-to-let does not automatically determine the classification.
The lender will still need to understand who currently occupies the property and who will live there after completion.
For example, a landlord may own a property that is rented to a parent, child or another close family member. That family occupation could affect how the application must be treated.
Any family connection should be disclosed at the beginning of the application rather than assuming the case is a standard unregulated buy-to-let transaction.
Can business-purpose borrowing secured against a home be unregulated?
Business purpose alone does not automatically make a bridging loan unregulated.
A business owner may want to raise capital against their home to fund a company expense. However, because the security is their main residence, the loan may still need to be considered under the regulated mortgage framework.
There are circumstances where business-purpose borrowing may be treated differently, but the classification depends on the full structure of the application.
The lender should be given clear information about:
- The property being used as security
- Who lives in the property
- The intended use of the funds
- The borrower’s business
- The proposed repayment strategy
The lender can then confirm whether the application falls within its lending criteria.
How is the regulatory status decided?
There is no single question that determines whether a bridging loan is regulated or unregulated.
The lender will normally consider several factors.
Who is borrowing?
An application from an individual may need to be treated differently from one made by a limited company.
What property is being used as security?
The lender will establish whether the property is residential, commercial, semi-commercial or held as an investment.
Who occupies the property?
This is one of the most important questions.
The lender will want to know whether the borrower or a close family member currently lives in the property or intends to live there.
What is the purpose of the loan?
The funds may be required for an investment purchase, refurbishment, capital raising or a business expense.
The purpose is important, but it must be considered alongside the security and occupation arrangements.
What is the exit strategy?
Every bridging loan needs a realistic route to repayment.
The lender will assess whether the proposed sale, refinance or alternative repayment source is credible and achievable within the required term.
What information should be provided?
A clearly explained application helps the lender understand the transaction and respond more quickly.
Whether you are applying directly or submitting a case for a client, it is helpful to provide:
- The borrower’s details and borrowing structure
- The security property address
- The property type and current condition
- The current and intended occupation
- The estimated property value
- The loan amount required
- The purpose of the funds
- The required completion date
- Details of any refurbishment work
- The proposed exit strategy
- Relevant property experience
- Details of any known credit issues
- Information about existing loans secured against the property
Not every application will require all of this information at the enquiry stage. However, a clear summary helps the lender identify any potential issues early.
Unusual occupancy arrangements, family connections or changes to the intended use of the property should always be highlighted.
