The Natwest mortgage criteria 

In this brief blog we are going to discuss the Natwest Mortgage criteria.

Natwest mortgage criteria

Natwest mortgages is a UK mortgage lender with a varying amount of mortgage products so when referring to the Natwest mortgage criteria this could be referring to any one of the Natwest mortgage products.

In this brief guide we will therefore provide the Natwest mortgage criteria for all Natwest mortgage products on offer at the time of writing. We will only point out the key Natwst mortgage criteria requirements which may affect most residential mortgage borrowers.

You can find a more detailed guide to the Natwest mortgage criteria here.

Age requirements

“Applicants must be at least 18 years old at the time of application. The maximum age at the end of term is 70. 


Our affordability calculator is the same one used by our underwriters:

·         Debts being repaid are not included in the calculation.

·         Pension costs are not included in the calculation.

·         Maximum age for lending is 70, subject to affordability, if lending is beyond the intended retirement age.

·         Assumes values for expenditure for basic essentials and quality living costs.

·         Forms of car finance, e.g. Personal Contract Purchase (PCP), Hire Purchase (HP), lease hire etc. should be included in our Calculator as committed expenditure regardless of the term remaining

·         If a customer still has an active car finance contract then the payment must be included unless the customer is repaying the finance prior to (or immediately following) completion from one of the following sources:

·         Savings (proof of savings required)

·         Equity from the sale of the property (home movers only)

·         Additional borrowing on their mortgage

·         Additional evidence may be required in relation to any of the above at the underwriter’s discretion.

·         When assessing the amount required to repay the car finance, you should also take into consideration any balloon payment which may be applicable as part of the agreement and discussions relating to this should be detailed within the application.

Bank statements

We accept internet bank statements in paper format, which don’t need to be certified by the issuing bank. However, they must show your client’s name and the account number. For supporting documents please refer to our packaging guide.


For guaranteed bonuses we will consider an average of the last two years’ payments (cash element only) and use 100% of it in our affordability calculation. Please note that if there has been a sharp decline in the latest year’s bonus the underwriter may use 100% of the most recent year’s bonus.

For discretionary bonuses we will consider an average of the last two years’ payments (cash element only) and use 50% of it in our affordability calculation. Please note that if there has been a sharp decline in the latest year’s bonus the underwriter may use 50% of the most recent year’s bonus. We will not consider deferred bonuses.

Builder’s Incentives

The maximum amount of acceptable incentive is 15% of the purchase price of the property.

Portable and proportionate incentives, such as carpets and curtains, along with other financial incentives such as support with up-front costs such as Stamp Duty, legal fees or cashback or enhanced part exchange terms can be accepted in the 5% allowance

Non-standard items such as an upgraded kitchen or integrated appliances can be accepted as an incentive but do not need to be included in the 5% allowance. It will be the responsibility of the valuer to decide which incentives are included in the calculation 

To comply with the requirements of the Help to Buy schemes, customers must still fund a 5% deposit themselves

Lending is based on the lower of the purchase price of the property or the property valuation

The purchase price will not be adjusted for incentives, unless the total amount of incentives exceeds 5% of the purchase price. Incentives greater than 5% will be deducted and lending based on the reduced purchase price (unless the property valuation is lower) The example below explains this for a New Build residential house:

– Purchase price of the property: £120,000

– Incentives total: £8,000

– Incentives to be deducted from purchase price: £8,000 – £6,000 (5% of purchase price) = £2,000

– Reduced purchase price: £120,000 – £2,000 = £118,000


Where a mortgage product includes a cashback feature, it will be paid to the customer’s solicitor with their mortgage funds on the day the customer completes. The customer should agree with their solicitor how they would like to receive the cashback.

Child Benefit

We can accept up to 100% of working tax credits, Child Tax Credits and Child Benefit. Please note that if an applicant is heavily reliant on these benefits (the ratio of benefits to main income) then please discuss these with your BDM but be aware that the final decision remains with the underwriter. The age of an applicant’s children may be a factor so we recommend submitting the awards letter with as part go the application packaging. If the applicant earns more than £50,000, then we will not include Child Benefit.

Childcare costs

We use the actual amount the customer has declared they pay in our affordability calculations for this commitment. Customers with dependants will be asked about the type of childcare they use, how often and how much they spend.

There is no formal evidence which is required for childcare costs, however if there is a difference between what is on the evidence provided as part of the application and the declared costs, this will be challenged/discussed to ensure the correct figure is used for the customer.

As part of the affordability discussion, you will need to clarify with the customer whether it’s certain or likely that childcare costs will change over the next 5 years. The highest figure should be used over the 5 year period.

In some circumstances childcare costs may be unknown, for example if the customer is currently pregnant, on maternity leave or if childcare arrangements are yet to be made. Customers can suggest likely future costs or you can refer to the national average figures here (figures correct as at August 2018)


For PAYE contract workers, we require one year’s evidence (for example, two six-month contracts or four three-month contracts) and a contract in place for minimum of a further three to six months.

For self-employed contractors who earn more than £75,000 pa we’ll calculate their income as their average weekly contract income multiplied by 46, provided they can confirm evidence of:

their latest 3 months’ consecutive personal bank statements for their main account (not required if their main account is with NatWest or RBS)         

where significant business expenses are identified on the application, 3 months’ consecutive bank statements (personal or business) detailing these

a copy of contract(s) to encompass a 12-month period, with a minimum of 6 months’ contract(s) already completed immediately preceding the date of application.

they have taken no more than a six week break between contracts in the 12-month period

the tax position is paid and up to date.

Many self-employed contractors may also trade via a Limited Company because it may be tax efficient for them to do so and subject to the criteria below we can help them under this policy . There is some additional information that you need to be aware of when submitting an application for a customer who meets these criteria:

When using the NWIS web site or MTE to submit an application, you must key the applicant as ‘Self-employed’ NOT ‘Employed’. 

Operating via a limited company. The applicant(s) must meet one of the following circumstances:

o   Single applicant owning 100% of the company

o   Joint application where one applicant owns 100% of the company

o   Joint application where the company is jointly owned

o   Joint application where one applicant owns 100% of the company and the other applicant is employed by the company (in this instance the employed applicant’s income should be excluded to avoid double-counting).

Significant business expenses not reimbursed as part of an applicant’s contract. Significant business expenses as detailed below, must be fully understood, evidenced and accounted for in the affordability calculation. Significant business expenses may be, though not limited to:

o   Car/finance loans

o   Extended travel and accommodation costs

o   Training courses

o   Professional indemnity insurance

o   Partner/spouse/employee salaries

Umbrella arrangements. We cannot use the high earning contractors’ criteria to consider applications from customers using an umbrella company arrangement. Under these circumstances we would consider an application under our PAYE contract worker policy.


This includes children under 18, those in higher education and financially dependent elderly relatives. Where the customer pays maintenance for a child, they should not be listed as a dependant.

Freehold Flats/Flying Freehold Properties

Acceptable but only where it is possible to enforce positive covenants against other occupants of the building i.e. a written agreement is in place to ensure maintenance, repair and insurance of the building and common parts are shared equitably amongst all residents

The valuation must confirm the property is readily saleable and a Solicitor confirms the Title is good and marketable

Maximum Loan to Value is restricted to 90%

AVM / HPI Valuations and the Fees Free Mortgage product are not suitable for this type of property

Gifted deposit: family gift

We accept deposits (and gifts) from parents and guardians and treat them as if they were the applicant’s own deposit. This applies even where the money is advanced against a formal loan agreement or a second charge is put in place to secure the parents’ rights.  Any monthly cost relating to a formal loan agreement must be included in the affordability calculation.

Transactions at undervalue / Gifted deposits – the purchase of a property  from a family member / family business where the purchase price is less than the value and the vendor does not receive any monies for the difference between the purchase price and the valuation. This situation is only permitted where there is a family connection and subject to the Solicitors providing a clear report on title or appropriate indemnity insurance. The maximum lend can be based on the Valuation not the actual purchase price.

Gifted deposit: third party

Gifts from third parties (not sellers/vendors) are an acceptable source of an applicant’s deposit, but only where there is no repayment required. We will require a signed letter from the third party confirming they have no interest in the property and that there will be no repayment required. The letter must be addressed to NatWest and confirm the amounts, who the money is coming from, who it’s going to and the relationship to the applicant. 

Gifted deposit: vendor

Deposits provided by a private vendor by way of a second charge or unsecured loan are not acceptable. Vendor gifted deposits, where no repayment is required, must be treated as an incentive and be deducted from the gross purchase price to establish the net purchase price of the property. If, for example, the vendor is offering to pay Stamp Duty/legal fees/cashback on the property being purchased this amount must be treated as an incentive and be deducted from the gross purchase price to obtain the net purchase price. We will base our maximum lend on the net purchase price or valuation whichever is the lower, with the applicant putting their own deposit in.


We do not currently support mortgages backed by a guarantor.

Help to Buy: shared equity (Purchase)

Help to Buy shared equity mortgages are open to all intermediaries and available for new build properties only. Please note the following information:

The equity loan must be repaid by the end of the mortgage term or upon the sale of the property, whichever comes first. The customer must take a mortgage of at least 25% of the value of the property they are purchasing.

Help to Buy: shared equity (Remortgage)

Customers with a Help to Buy Shared Equity mortgage with another lender will be able to remortgage to us on a like for like basis, keeping the same balance and term.

Our solicitors will act on behalf of the customer to process their application and provide the scheme administrator, Target, with the necessary paperwork.

If a customer is looking to repay any shared equity loan then we can also help with any of our standard remortgage products.

3% of the equity share will need to be factored into the affordability calculation as a monthly commitment.

A new build is defined as any property built, first occupied in its current state or significantly modernised, refurbished or altered within the last two years.

The maximum loan-to-value on a residential new build house is 85% (65% for buy-to-let). For a residential new build flat, the maximum is 75% (65% for new build buy-to-let flats). The amount will be calculated on the net purchase price or the valuation, whichever is the lower.  Also see ‘Builder’s Incentives’ and ‘Offer of Loan – validity’
