What does sitting behind a senior commercial lender actually mean?
A second-charge commercial mortgage sits behind your existing first-charge facility, secured against the same property. The senior lender retains priority on the asset; the second-charge lender takes a subordinated position, meaning that in any default scenario, the senior gets repaid in full before the second-charge sees a penny. You keep the existing senior facility intact (and its interest rate) while raising additional debt against the same security.
The use case is narrow but valuable. Typically: your existing first charge is on a competitive legacy interest rate (3.5 to 4.5% from the 2019 to 2021 era) with significant ERCs to break; you need to raise £200K to £2M for working capital, business growth, partner buy-out or onward acquisition; refinancing the whole stack would cost more than the second-charge route. Run the maths and second-charge often wins on a 3-year horizon, particularly where the legacy rate has 18+ months left to run.
It is a smaller, more specialist market than first-charge. InterBay Commercial, LendInvest and select private-credit desks are the active second-charge commercial lenders for the Cambridge market. Pricing reflects the subordinated risk profile: 10 to 14% pa typically, with arrangement fees of 2 to 3%. Combined loan-to-value (first charge plus second charge) usually capped at 70 to 75% on owner-occupier and standard investment, occasionally flexed to 80% on strong covenant cases.
Most second-charge commercial lending is taken out by a limited company trading entity or SPV with director personal guarantee, and is unregulated commercial lending, not a residential mortgage. The senior lender has to consent to the second charge being registered (a deed of consent at typically £500 to £2K is standard); some clearing bank commercial desks refuse on policy grounds, in which case the route is closed and refinancing the whole stack is the only option. Stamp duty does not apply on a second-charge (no transfer of ownership). Repayment is on a standard amortising basis or, occasionally, interest-only with a balloon at year 5; we structure based on the cash-flow profile of the underlying business. Indicative case seed: a Cambridge investor with a £900K legacy first charge at 4% on a central commercial freehold (3 years left to run) raises £600K of equity via a second-charge at 12% pa to fund a Mill Road semi-commercial acquisition, without disturbing the cheap senior.
Process: from senior consent to subordinated drawdown
1. Combined-LTV review
Current first-charge balance, current property valuation, target combined loan-to-value. Most second-charges sit at 70 to 75% combined.
2. First-charge consent check
Existing senior lender must consent to the second charge being registered. Some refuse on policy; most allow with a deed of consent fee.
3. Indicative terms in 48 hours
From two to three specialist subordinated desks. Interest rate, LTV, term, fees, conditions.
4. Credit pack
Standard commercial credit pack plus first-charge documentation. Lenders want clarity on the priority position and any cross-default clauses in the senior.
5. Valuation and intercreditor
RICS Red Book valuation. Deed of priority / intercreditor agreement between senior and second-charge lenders. Adds 1 to 2 weeks vs first-charge process.
6. Completion and drawdown
Funds drawn. First-charge facility unaffected. 5 to 7 weeks total typical from indicative to drawdown.

- Asset-rich borrowers with cashflow pressure needing capital release without facility break
- Investors funding partner buy-outs without disturbing senior portfolio relationships
When subordinated debt is doing real work in the Cambridge market
InterBay Commercial, LendInvest and select private-credit desks are the active second-charge commercial lenders for Cambridge. The product sees most use on two distinct Cambridge profiles. First, capital raise on Cambridge investor portfolios: an investor with a cheap legacy first charge on a Mill Road semi-commercial block or a CSP-adjacent office investment needs equity for the next acquisition, and the second-charge route preserves the original cheap rate. Second, central commercial freehold equity release: an asset-rich owner of a Sidney Street, Hills Road or St Andrew's Street freehold raises capital for business growth without breaking the senior. Combined first plus second LTV usually capped at 70 to 75% on owner-occupier; investment assets sometimes flex to 80% combined. On a £2M owner-occupied Hills Road professional services freehold with a £800K legacy first charge at 4% (with 3 years left), a £600K second-charge at 12% costs less in absolute terms than a full refinancing of the £1.4M total at 7.5% with a £40K ERC, by around £24K over three years. We run the same comparison for Mill Road semi-commercial investors, Cambridge Science Park-adjacent lab investors and central retail freeholders before recommending.
