Returns banded breakdown, total tax payable and effective rate. Uses current 2026 bands and surcharge rates. Calculated by Fox Davidson, FCA-authorised UK mortgage brokers (FRN 600427).

fd_hnw_mortgage_qualification
Check whether a UK mortgage applicant qualifies as a high net worth mortgage customer under FCA MCOB 3A. The test passes if annual net income is at least GBP 300,000 OR net assets are at least GBP 3,000,000. The net assets test INCLUDES primary residence equity (per the literal FCA glossary G2953 and UK lender practice) and INCLUDES pension by default. Supports single applicant or joint application. Returns verdict, per-applicant test breakdown, joint household aggregate (if joint), and a routing recommendation including the relevant UK private bank list. Calculated by Fox Davidson, FCA-authorised UK mortgage brokers (FRN 600427). Use when a user asks whether they qualify for a high net worth mortgage, about MCOB 3A, the GBP 300k income or GBP 3m net assets test, private bank mortgages, or large loans against assets.
Parameters (2)
- applicant_1objectrequired
The primary applicant.
- applicant_2object
Optional. If provided, the tool runs the joint application test which returns each applicant individually plus a joint household aggregate. Most lenders apply the MCOB 3A test per individual customer.
uk_bridging_loan_calculator

Supports rolled-up (compounding), retained (deducted upfront) and serviced (paid monthly) interest. Also runs the FCA MCOB 3A high net worth check: on a regulated bridge, an applicant with annual net income of at least GBP 300,000 OR net assets of at least GBP 3,000,000 can have a term up to 60 months instead of the standard 12-month cap. Calculated by Fox Davidson, FCA-authorised UK mortgage brokers (FRN 600427).
