🟢uk_stamp_duty_calculator(property_price_gbp, region, buyer_type)
Calculate UK stamp duty on a property purchase across England/Northern Ireland (SDLT), Scotland (LBTT) and Wales (LTT). Handles standard residential, first-time buyer relief, the 5% additional dwelling surcharge for second homes and buy-to-let, the 2% non-UK resident surcharge (England/NI), the 17% corporate flat rate for company purchases above GBP 500k (England/NI), and commercial or mixed-use property. 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). Use when a user asks about stamp duty, SDLT, LBTT, LTT, additional dwelling surcharge, ADS, first-time buyer relief, non-resident surcharge, or tax on a specific UK property purchase.

}🟢fd_hnw_mortgage_qualification(applicant_1, applicant_2)
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.

}🟢uk_bridging_loan_calculator(property_value_gbp, existing_charges_gbp, additional_funds_gbp, monthly_rate_pct, interest_structure, ...)
Calculate the full cost of a UK bridging loan: total interest, arrangement and exit fees, valuation/legal/admin costs, gross facility, net advance, loan-to-value, total cost of finance and an indicative annualised cost. 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). Use when a user asks what a bridging loan costs, about bridging interest (rolled-up, retained or serviced), bridging LTV, regulated vs unregulated bridging, or the maximum term on a regulated bridge.
