Step 01

The Challenge

A UK FCA-authorised savings platform (aggregating savings products from multiple FCA-authorised banks and building societies -- 42,000 customers, GBP280M AUM) needed to build a multi-bank savings marketplace. FCA COBS (savings products conduct), FCA Consumer Duty, FSCS (Financial Services Compensation Scheme -- GBP85,000 per institution protection), HMRC ISA Manager authorisation (Cash ISA), HMRC ISA transfers (ISA Transfer Authority), AML MLRs 2017, UK GDPR, ISO 27001. Budget GBP130,000.

Step 02

Our Approach

FCA COBS Savings Product Compliance

FCA COBS (Conduct of Business sourcebook) for savings: (1) product disclosure (savings rates must be prominently displayed -- COBS 6 financial promotions -- rate, term, conditions), (2) easy access vs fixed term (COBS disclosure for fixed-term savings -- what happens at maturity, early withdrawal penalties), (3) consumer understanding (COBS consumer understanding outcome -- savings product description in plain English, Grade 8 or below Flesch-Kincaid), (4) fair value (Consumer Duty fair value outcome -- savings rate must represent fair value vs bank deposit rate -- compare platform fee to rate benefit), (5) product governance (Consumer Duty product governance -- each savings product has a target market and fair value assessment).

HMRC Cash ISA Manager

savings platforms offering Cash ISAs must be authorised as HMRC ISA Managers.

ISA Manager requirements

  • 1HMRC ISA Manager application (application to HMRC Savings and Financial Resilience team -- approval 3-6 months),
  • 2ISA Manager obligations (annual ISA return to HMRC -- ISAPAAF data),
  • 3ISA subscription limit enforcement (GBP20,000 ISA allowance per tax year -- platform must enforce per-customer subscription limit across all ISA types),
  • 4ISA transfer authority (ISA Transfer Authority form -- customer transfers ISA from one manager to another -- 15-business-day transfer SLA),
  • 5ISA repair (HMRC ISAPAAF error correction -- reporting invalid subscriptions to HMRC).

ClickMasters HMRC ISA API integration

  • automated annual ISA return and transfer authority processing.
  • FSCS Protection Display and Multi-

Bank Optimisation

  • FSCS (Financial Services Compensation Scheme): deposits with FCA-authorised banks protected up to GBP85,000 per institution per customer.
  • Multi-bank savings platform

FSCS display

  • 1per-institution FSCS status (each savings provider -- which FSCS institution they belong to -- shared institutions share the GBP85,000 limit),
  • 2FSCS optimisation (customer with > GBP85,000 savings -- platform recommends spreading across institutions for full FSCS coverage),
  • 3FSCS calculator (interactive tool -- customer enters total savings, platform calculates FSCS exposure per institution),
  • 4FSCS disclosure (every product page -- FSCS protection status prominently displayed -- FCA financial promotion requirement),
  • 5FSCS information (PRA Eligible Deposits and Covered Deposits Regulations 2015 -- annual FSCS information sheet to customers).

AML MLRs 2017 for savings

  • 1KYC at onboarding (Onfido identity verification -- UK passport/driving licence),
  • 2source of funds (for deposits > GBP10,000 -- source of funds evidence),
  • 3PEP/sanctions screening (ComplyAdvantage -- all customers screened at onboarding and annually),
  • 4transaction monitoring (suspicious deposit patterns -- round-number large deposits, rapid in-out),
  • 5SAR filing (NCA goAML within 24 hours of decision to file).

AML considerations specific to savings

  • 1structuring (customer makes multiple deposits just below GBP10,000 -- structuring alert),
  • 2introduction of proceeds (large deposit from unexpected source -- EDD triggered),
  • 3dormant account reactivation (dormant account suddenly active with large deposit -- alert).
Step 03

The Results

FCA COBS and Consumer Duty confirmed.

HMRC ISA Manager authorised.

Platform live at 26 weeks, GBP122,000. 42,000 customers.

GBP280M AUM.

ISA transfer authority: average 9.2 business days vs 15 SLA.

FSCS optimisation: 28.4% of customers with > GBP85,000 diversified across institutions.

HMRC annual ISA return: automated.

AML: 100% screened.

ISO 27001 maintained.

Consumer Duty fair value: confirmed.

ISA transfer 9.2 days vs 15 SLA.

FSCS optimisation 28.4%.

HMRC annual return automated.

AML 100%.

ISO 27001.

Consumer Duty confirmed.

The FSCS optimisation feature -- showing customers with more than GBP85,000 that their money is exposed and recommending how to spread it across institutions for full protection -- was the feature that generated the most customer trust.

It was the feature that cost us short-term revenue (customers spread money to other platforms) and generated long-term loyalty (customers stayed because we told them the truth about their money).

Consumer Duty is not just compliance.

It is business strategy. -- CEO, UK Savings Platform
