The partnership with the estate agent will see Savills supplying mortgage and insurance products to Exceptional's buyers and sellers.
The estate agent is the only one in the UK to cater solely for £1 million plus properties.
Founder and managing partner of Exceptional Homes, Dr Jeremy Howard, said: “What we liked about Savills Private Finance (SPF) was their customer-centric approach to financing. A lot of financial companies make this claim, but in the end they offer a limited range of ‘cookie cutter’ products.
"Our customers need access to non-standard mortgage, insurance and other financial services. And the expertise of SPF in putting together creative financial solutions will be of significant benefit to our customers.
"SPF also shares our commitment to delivering personalized service in a thoroughly modern context, which is also very important to us.”
