At NatWest Intermediary Solutions service is our number one priority, and we are dedicated to being there for our brokers when they need us most. We are the dedicated intermediary arm of NatWest and offer brokers an extensive range of mortgages designed for first-time buyers, home movers, remortgagers and buy-to-let investors.

BDM partnership model

Our BDM partnership model ensures a tailored and effective service to brokers, as brokers receive the support of one field and one phone BDM. We have made a great effort to make our service more seamless and broker friendly and with our phone and field BDMs possessing great strengths and knowledge in their respective areas, the new pairings will see brokers inherit the best of both levels of support.

New Build

We’re delighted with the enhancements we’ve been able to make with our new build proposition.      We appreciate new build properties can take longer than 6 months from the customer agreeing to purchase the property to getting the keys. So to acknowledge the complexities of the new build process we have introduced an offer extension process for new build cases.

Brokers can now request an extension to an existing mortgage offer, at any point within the initial 6 month offer period. This means that customers could have a total offer period of up to 12 months. This will be subject to the confirmation of a successful credit search and property valuation.

Brokers can request an extension by populating an offer extension template here where they will need to provide a declaration confirming any detrimental financial change to the customer’s circumstances since the initial assessment. The offer extension will be valid for 6 months from the point the extension is agreed.

Take a look below to see some more highlights of our service:

Acceptable Income types

We accept a wide range of income types. Click here and we’ll highlight the varied types of income that we can consider at 100%, including multiple income streams such as multiple jobs along with child benefits and also foster care income. Make sure you ask your customers to declare all of their income sources as this could have a beneficial impact on the amount we are able to lend them.


We’ve enhanced our buy-to-let offering to ensure we’re there for a wider range of customers. We have now increased the total number of buy-to-let properties we will allow a landlord customer to own from 4 to 10. The total includes any unencumbered properties and properties mortgaged with ourselves and another lender.

The maximum aggregate customer borrowing allowed has been increased to £3.5m, which is up from £2m. The current £50,000 minimum income for aggregated borrowing over £1m has been removed. All customers will be required to meet our standard buy-to-let minimum income of £25,000.

There when you need us most

We want to support brokers and customers through their mortgage journey wherever we can. That’s why our underwriters will leave their direct dial during communications with brokers, so they can be easily accessed for discussions around the underwriting process.  Also, our dedicated LiveTALK team is on hand to complement the proactive guidance provided by our BDMs. They can give you an instant answer to questions regarding an application before you submit, be it about lending criteria, packaging or just to check a rate. If you are registered with us you can access the LiveTALK service via the Links section to the right, or from our home page.
