What ICS Mortgages does

Dilosk DAC, trading as ICS Mortgages, is an Irish non-bank residential mortgage lender founded in 2013 and headquartered in Dublin. The company acquired the ICS Mortgages brand, distribution platform, and an initial ~€223 million mortgage portfolio from Bank of Ireland in September 2014 for €250 million, and has since grown to manage approximately €1.9 billion in residential mortgages across two core product lines: Buy-to-Let Mortgages for individual and corporate property investors, and Owner-Occupier Mortgages for primary residence buyers, with specialized add-ons including a Public Sector Employee mortgage, a 10-year interest-only BTL product, a 35-year Flexi-Mortgage, a Pension Unit Trust BTL product, and Bridging Loans. ICS Mortgages differentiates through a #1-ranked broker distribution network in Ireland, product innovation in the BTL segment where it holds approximately 30% market share, and the 160+ year heritage of the ICS brand originally established in 1864 as the Irish Civil Service Building Society.

The business model is asset-spread mortgage lending: revenue is generated primarily through net interest income on the held mortgage portfolio, supplemented by arrangement/origination fees on new loans. Lending is funded almost entirely through capital markets rather than deposits, with Dilosk having executed more than 10 public Residential Mortgage-Backed Securities (RMBS) transactions totaling over €2.6 billion since 2015, complemented by a €900 million warehouse facility and a €500 million Bank of Ireland RMBS purchase commitment. The proprietary technology stack centers on specialized origination systems for BTL and Owner-Occupier segments plus an ESG-focused IoT sustainability monitoring platform for internal facilities. The company is regulated by the Central Bank of Ireland as a Retail Credit Firm, is GDPR-compliant, and is privately held with founders Fergal and Oran McGrath controlling 50.1%, management and family 16%, and London-based Chenavari Investment Managers and Attestor Capital holding the remaining 34%.

Revenue model

1. Mortgage Interest Income: ICS Mortgages generates primary revenue through interest income on its residential mortgage portfolio. The company originates and holds mortgages for both Buy-to-Let and Owner-Occupier customers, earning interest on these loans over their terms.
2. Mortgage Origination Fees: The company earns arrangement fees on new mortgage originations. Recent data shows arrangement fees for bridging loans at 1% (reduced from 2%). Standard mortgage products also generate origination-related fees.
3. Securitization/Sale of Mortgage Assets: Dilosk raises capital by issuing Residential Mortgage-Backed Securities (RMBS) in public bond markets. The company has completed multiple securitizations (RMBS No. 1 through No. 10) totaling over €2.6 billion raised. This is the primary funding mechanism for the non-bank lender.

Regional players

• Foundation Home Loans: UK specialist mortgage lender focused on BTL, complex income, and later-life lending. Highly comparable product mix to ICS Mortgages but operates in a different geography (UK) and so does not directly compete in Ireland.
• Paragon Bank: UK specialist bank with significant buy-to-let mortgage origination. Comparable specialist-mortgage business model but primarily UK-focused, making it a regional rather than direct competitor to ICS Mortgages.
• Together Money: UK specialist lender offering residential, BTL, and bridging finance with a securitisation-led funding model. Similar specialist lender profile to ICS Mortgages, but UK-focused rather than competing in Ireland.

Direct peers

• Avant Money: Irish non-bank mortgage and personal-loan provider, regulated by the Central Bank of Ireland. Directly competes with ICS Mortgages in Irish owner-occupier and BTL markets using a similar capital-markets-funded origination model.
• Finance Ireland: Major Irish non-bank lender offering residential mortgages, BTL, and asset finance. Receives funding under the same CCPC-mandated Bank of Ireland €1B non-bank RMBS program as Dilosk, making it a near-direct competitor on product and funding profile.
• Pepper Money (Ireland): Irish non-bank lender (Pepper Finance Corporation Ireland DAC, mentioned in the Dilosk data as servicing partner). Offers specialist residential and BTL mortgages, comparable origination scale and customer segments to ICS Mortgages.

Broad incumbents

• Bank of Ireland: One of the Irish pillar banks and the original owner of the ICS brand until the 2014 sale to Dilosk. Now a major RMBS investor for Dilosk and a competitor in the residential mortgage market via its branch and broker network.
• Permanent TSB: Irish challenger bank with a focused mortgage franchise serving owner-occupier and BTL borrowers. A traditional depository competitor whose presence in the Irish mortgage market ICS Mortgages competes against, particularly via the broker channel.
• AIB (Allied Irish Banks): Largest Irish pillar bank by mortgage book and the dominant incumbent competitor. Sets the price benchmark that non-bank lenders like ICS Mortgages position against in owner-occupier and BTL markets.

Emerging players

• Molo Finance: UK digital-only specialist BTL mortgage lender. Operates in an adjacent geography with a comparable BTL-specialist proposition and digital-first operating model that parallels ICS Mortgages' BTL franchise.
