Mortgage advisers need accurate lending information, suitable mortgage products and a reliable way to manage customer applications. Finding the right information quickly can make the difference between a smooth application and unnecessary delays. NatWest Intermediary provides a dedicated service that helps registered mortgage professionals access lending criteria, check affordability, review available deals and manage mortgage applications through its broker facilities.
1. What Is NatWest Intermediary Solutions?
NatWest Intermediary Solutions is the mortgage intermediary service operated by NatWest, a UK banking brand within National Westminster Bank plc. It supports professional mortgage advisers and intermediaries who want to arrange eligible NatWest mortgage products for their customers.
The service gives registered brokers access to tools and information needed throughout the mortgage application process.
Rather than asking customers to manage every part of the application themselves, mortgage advisers can use the intermediary platform to research lending options, assess eligibility and submit applications.
What does the service offer?
The main facilities include:
- Mortgage products: Information about available residential and Buy to Let mortgage deals.
- Affordability tools: Calculators to estimate potential borrowing.
- Lending criteria: Guidance about applicant eligibility, income and property requirements.
- Broker portal: Access to mortgage applications and case management.
- Product transfers: Support for eligible existing NatWest mortgage customers.
- Additional borrowing: Facilities for customers who need further funds.
- Broker support: Contact options for technical questions and application assistance.
The service is designed for professional mortgage intermediaries rather than general banking customers. Access to broker facilities requires the appropriate registration and account credentials.
2. How Does NatWest Intermediary Work?
The service follows a broker-led process. A mortgage adviser reviews the customer’s circumstances, checks relevant lending policies and uses the available tools to identify a suitable mortgage option.
The typical process involves the following stages:
| Stage | What happens | Why it matters |
|---|---|---|
| Registration | The adviser registers with NatWest | Establishes broker access |
| Customer assessment | The adviser reviews income and financial commitments | Helps assess eligibility |
| Affordability check | The appropriate calculator is used | Estimates potential borrowing |
| Product research | Available mortgage deals are reviewed | Helps identify suitable options |
| Application | The adviser submits the mortgage application | Starts the formal assessment |
| Case tracking | The adviser monitors application progress | Identifies outstanding requirements |
| Completion | The mortgage progresses through the lender’s process | Finalises the transaction |
Each stage has a different purpose. For example, passing an affordability calculation does not mean that NatWest has approved the mortgage. The lender still needs to assess the application against its full underwriting requirements.
3. What Mortgage Products Does NatWest Offer Through Its Intermediary Service?
Mortgage product availability depends on the customer’s circumstances, property type, borrowing requirements and the lender’s current pricing.
Through its intermediary facilities, NatWest provides information about different mortgage categories.
The main categories include:
| Mortgage category | Description | Typical customer requirement |
|---|---|---|
| Residential mortgages | Finance for a property used as the customer’s home | Home purchase or remortgage |
| First-time buyer mortgages | Residential borrowing for eligible first-time buyers | Purchasing a first property |
| Remortgage products | Replacing an existing mortgage with a new arrangement | Reviewing borrowing or mortgage rates |
| Buy to Let mortgages | Finance for eligible rental properties | Purchasing or refinancing an investment property |
| New-build mortgages | Mortgage options for eligible newly constructed properties | Purchasing a new-build home |
| Interest-only mortgages | Borrowing where monthly payments cover interest rather than capital repayment | Applicants meeting specific lending requirements |
| Additional borrowing | Further borrowing against an existing property | Funding eligible additional expenses |
| Product transfer deals | Switching an existing NatWest mortgage to another available deal | Existing eligible NatWest customers |
Important: This table describes mortgage categories, not a guarantee that every category or deal is currently available to every applicant. Brokers should check the live product information before making recommendations.
How can brokers compare mortgage products?
When reviewing NatWest mortgage products, advisers should consider more than the initial interest rate.
Important factors include:
- Interest rate and whether it is fixed or variable.
- Initial mortgage period.
- Product and arrangement fees.
- Loan-to-value (LTV) requirements.
- Early repayment charges.
- Monthly repayment amount.
- Mortgage term and repayment method.
- Customer eligibility and lending conditions.
A mortgage with a lower initial rate may not always represent the most suitable overall option. Advisers should consider the customer’s financial position and longer-term requirements.
4. How to Access NatWest Intermediary Login
The intermediary login facility allows registered mortgage advisers to access the broker portal and manage their mortgage-related activities.
A valid account is required before an adviser can use the restricted services.
Steps to log in
Follow these general steps:
- Open the official NatWest Intermediaries website.
- Select the Log in option.
- Enter your registered login credentials.
- Complete any required security checks.
- Access the relevant broker portal facility.
- Select the service you need, such as product research, application management or case tracking.
The available facilities depend on your account permissions and registration status.
What if you cannot access your account?
Login problems can occur because of incorrect credentials, forgotten passwords, account verification issues or temporary technical difficulties.
Try these steps:
- Check that your username and password are correct.
- Make sure your browser is working properly.
- Follow the available password recovery instructions.
- Contact NatWest intermediary support if the problem continues.
NatWest also provides WhatsApp support for account access and password-reset assistance during its published operating hours.
Who can use the broker login?
The broker portal is intended for registered mortgage intermediaries and authorised users. A general NatWest online banking account should not be confused with a mortgage intermediary account.
5. How Does the NatWest Intermediary Calculator Work?
The NatWest intermediary calculator helps mortgage professionals estimate how much a customer may be able to borrow.
It is an important part of the initial mortgage assessment because it allows advisers to review potential borrowing before submitting a full application.
NatWest provides different affordability calculators for different borrowing requirements.
Types of affordability calculators
| Calculator | Main purpose | Suitable assessment |
|---|---|---|
| Residential affordability calculator | Estimates residential borrowing capacity | Home purchase and remortgage |
| Residential additional borrowing calculator | Assesses potential additional residential borrowing | Existing residential mortgage customers |
| Buy to Let affordability calculator | Assesses borrowing for rental properties | Eligible landlords and property investors |
What information may be required?
The calculator considers relevant financial information about the customer.
This can include:
- Gross annual income.
- Employment and income arrangements.
- Regular financial commitments.
- Existing loans and credit agreements.
- Credit card and store card commitments.
- Overdraft balances.
- Dependants and childcare expenses.
- Property and mortgage details.
- Pension contributions and other relevant expenditure.
The exact information required depends on the calculator and the application type.
Is the calculator an approval tool?
No. An affordability result is an initial indication, not a mortgage offer or a formal agreement to lend.
NatWest confirms that its calculators do not conduct a credit search. The indicative borrowing amount can change when the customer proceeds to an Agreement in Principle or a full application.
The lender may also consider credit reference information, income evidence, property details and other underwriting requirements.
Therefore, advisers should use the calculator as an assessment tool rather than a promise of approval.
6. NatWest Intermediary Lending Criteria: What Do Brokers Need to Know?
Lending criteria determine whether a mortgage application meets the lender’s requirements.
Before recommending a NatWest mortgage, advisers should examine the customer’s financial position, employment, credit history and property circumstances.
The official lending criteria cover several important areas.
Income and employment
The lender assesses whether the applicant has an acceptable and sustainable income.
Relevant considerations may include:
- Employed income.
- Self-employed earnings.
- Employment history.
- Probationary employment.
- Additional income sources.
- Pension contributions.
- Future changes in income.
Different income types may require different supporting documents.
Credit history
Credit history helps lenders understand how an applicant has managed financial commitments.
NatWest uses credit reference agency information and considers relevant account conduct when assessing applications.
Adverse credit does not automatically mean that every application will receive the same outcome. However, specific credit events and the lender’s current policies can affect eligibility.
Property requirements
The property must satisfy the lender’s relevant security and valuation requirements.
The assessment may consider:
- Property type.
- Property condition.
- Location.
- Market valuation.
- Loan-to-value ratio.
- Leasehold or freehold arrangements.
- Property-specific restrictions.
Age and mortgage term
Applicants must meet the lender’s minimum age requirements. Maximum age limits can depend on the mortgage repayment type and the applicant’s circumstances.
For example, NatWest publishes different maximum age requirements for capital-and-interest and interest-only residential mortgages.
Financial commitments
Affordability is not based on income alone. Existing debts and regular expenses can reduce the amount a customer may be able to borrow.
Brokers should provide accurate information about the customer’s financial commitments when completing the assessment.
The most important principle is to check the latest policy rather than rely on an old lending decision or an outdated affordability estimate.
7. How Does NatWest Intermediary Affordability Assessment Work?
Affordability is one of the most important parts of mortgage underwriting.
The assessment helps determine whether a customer can reasonably manage the proposed mortgage repayments alongside their existing financial commitments.
NatWest considers relevant income and expenditure information when assessing residential mortgage affordability.
Main factors affecting affordability
| Factor | How it affects affordability |
|---|---|
| Annual income | Helps establish the customer’s earning capacity |
| Monthly expenditure | Shows how much income remains after regular expenses |
| Existing loans | Reduces available income for mortgage repayments |
| Credit commitments | Affects the overall financial assessment |
| Dependants | Can increase household expenditure |
| Childcare costs | May reduce available disposable income |
| Pension contributions | Can affect the affordability calculation |
| Loan-to-income ratio | Helps determine borrowing limits |
| Loan-to-value ratio | Measures the mortgage against the property value |
What is the difference between affordability and loan-to-income?
These terms are related, but they do not mean the same thing.
Affordability examines whether the customer can manage the mortgage repayments after considering their financial circumstances.
Loan-to-income (LTI) measures the mortgage amount against the applicant’s income.
For example, if a customer earns £50,000 annually and requests a £200,000 mortgage, the loan-to-income ratio is 4.
However, a 4-times-income calculation does not automatically mean that the lender will approve the borrowing. Other lending conditions and affordability checks still apply.
How can advisers improve the accuracy of affordability assessments?
Mortgage advisers should:
- Enter accurate income information.
- Include relevant monthly commitments.
- Check the customer’s credit obligations.
- Review pension contributions.
- Confirm the correct mortgage purpose.
- Use the appropriate calculator.
- Recheck the latest lending criteria before submitting the application.
Correct information helps reduce avoidable application problems and gives the customer a clearer understanding of potential borrowing.
8. How Does NatWest Intermediary Product Transfer Work?
A product transfer allows an existing NatWest mortgage customer to switch to another eligible mortgage deal without moving their mortgage to a different lender.
This option can help customers review their mortgage rate when their current deal approaches its expiry date.
The NatWest intermediary product transfer facility allows registered advisers to review eligible deals and manage the switching process through the broker portal.
Who can qualify for a product transfer?
According to NatWest’s published policy, product transfers are available for eligible residential and Buy to Let customers who meet relevant conditions.
These include:
- Customers within four calendar months of their existing deal ending.
- Customers currently on the Standard Variable Rate (SVR).
- Eligible customers within the track-and-switch period on a tracker mortgage.
- Customers meeting the minimum £10,000 loan requirement.
- Customers with more than 27 months remaining on their mortgage term when applying.
Other conditions may apply depending on the customer’s mortgage account.
Product transfer application process
| Step | Action |
|---|---|
| 1 | Log in to the NatWest broker portal |
| 2 | Select the product transfer facility |
| 3 | Enter the customer’s mortgage account number |
| 4 | Provide the surname, postcode and date of birth |
| 5 | Review the available mortgage deals |
| 6 | Select an eligible product |
| 7 | Complete the application process |
| 8 | Follow the instructions for customer acceptance |
NatWest states that customers generally have 14 calendar days to accept the product transfer offer. If they do not accept within that period, the application is automatically cancelled.
Standalone product transfers do not require additional underwriting under the published process. However, additional borrowing remains subject to underwriting.
Can customers borrow additional money during a product transfer?
Yes, eligible customers can apply for additional borrowing alongside a product transfer.
The lender will assess the additional borrowing request against the relevant affordability and lending requirements.
This means that an existing mortgage customer may be able to review their interest rate and request further borrowing as part of the same overall process.
9. How to Complete NatWest Intermediary Registration
Mortgage advisers who want to submit business through NatWest must complete the appropriate registration process.
NatWest provides separate registration routes for mortgage intermediaries and administrators.

This access is designed to allow authorised administrative users to attach supporting documentation to submitted full mortgage applications.
According to NatWest’s registration guidance, administrators receive their login details and temporary password by email immediately after completing registration.
What should advisers prepare before registering?
It is sensible to have the following information available:
- Personal and professional details.

Choosing the correct registration category helps avoid unnecessary delays.
