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, deposit on the next HMO acquisition or onward expansion of a Portsmouth portfolio; 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 Portsmouth market. Paragon and Together engage on second-charge against HMO portfolios. 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; Portsmouth lenders read combined LTV carefully on tourism-led seafront stock and on concentrated HMO blocks where the cover test is more sensitive to void exposure.
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 Portsmouth HMO portfolio operator with a £1.7M legacy first charge at 4.0% on a five-block Southsea sui generis book (2.5 years left to run) raises £620K of equity via a second-charge at 12% pa to fund a sixth-block acquisition along the Kirby Road North End corridor, 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 or intercreditor agreement between senior and second-charge lenders. Adds 1 to 2 weeks versus first-charge process.
6. Completion and drawdown
Funds drawn. First-charge facility unaffected. 5 to 7 weeks total typical from indicative to drawdown.

When subordinated debt is doing real work in the Portsmouth market
InterBay Commercial, LendInvest and select private-credit desks are the active second-charge commercial lenders for Portsmouth, with Paragon and Together engaging on the HMO portfolio side. The product sees most use on two distinct Portsmouth profiles. First, capital raise on Portsmouth HMO portfolios: a multi-block Southsea or North End sui generis HMO operator with a cheap legacy first charge needs equity for the next acquisition through the live planning pipeline (Manners Road, Kirby Road, the Portsea fringe). The second-charge route preserves the original cheap rate against an asset where refinancing the whole stack would trip break costs that outweigh the rate saving. This is the deepest second-charge driver in our network given Portsmouth's exceptional HMO conversion volume. Second, central freehold equity release: an asset-rich owner of an Old Portsmouth, Gunwharf-adjacent, Commercial Road or Cosham 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, with Portsmouth lenders weighing combined LTV carefully on tourism-led seafront retail and on concentrated HMO blocks. On a £1.8M owner-occupied Cosham professional services freehold with a £750K legacy first charge at 4% (with 3 years left), a £540K second-charge at 12% costs less in absolute terms than a full refinancing of the £1.29M total at 7.5% with a £36K ERC, by around £22K over three years. We run the same comparison for Portsmouth HMO portfolio operators, central freehold owners and Albert Road semi-commercial investors before recommending. See also our commercial remortgage route where the whole-stack refinancing actually beats the second-charge maths.
