Commercial Mortgages Southwark
Southwark stretches 11.14 square miles from the river at Bankside down to Dulwich, and it carries more Opportunity Areas than any other central borough. Elephant and Castle, Canada Water, Old Kent Road and London Bridge with Bankside are all designated. We arrange commercial mortgages across SE1, SE5, SE15, SE16, SE17, SE21 and SE22 on shops, offices, restaurants, mixed-use blocks and semi-commercial titles.
A commercial mortgage in Southwark is long-term secured debt against business premises, underwritten on rental cover, trading profit or EBITDA depending on how the property is held. Commercial Mortgages London is a specialist commercial mortgage broker arranging owner-occupier, investment, semi-commercial and trading-business mortgages across Southwark.
Main postcodes: SE1, SE5, SE15, SE16, SE17, SE21, SE22. London outcodes cross borough boundaries, so this is the core set rather than an exhaustive one.
Southwark does not publish a machine-readable planning register we can read, so this page leads with transaction data rather than estimating planning volumes.

The London Borough of Southwark commercial property market
Southwark is the historical origin point of south London and now one of its busiest development boroughs. It holds around 312,000 residents across 11.14 square miles. Lambeth and Southwark together held 1,780,000 square metres of office floorspace on the last full sub-market breakdown, a 2001 figure that reads as relative scale. Four of London's 47 Opportunity Areas sit inside the borough: Elephant and Castle, Canada Water, Old Kent Road, and London Bridge with Bankside. The London Plan also designates Elephant and Castle with Walworth Road, Canada Water and Peckham as Major centres, and Camberwell in SE5 as a District centre. That is an unusual concentration of designated commercial growth for a single borough.
The submarkets are genuinely different from one another. Bankside and London Bridge in SE1 are riverside office and leisure and have their own page on this site. Bermondsey runs a mix of converted warehouse office, food production and independent retail. Rotherhithe and Canada Water in SE16 are regeneration led, with new ground-floor commercial floorspace coming forward inside residential-led schemes. Peckham in SE15 is a Major centre with a strong independent retail and night-time economy and a large stock of shop-with-flats-over titles. Camberwell in SE5 is neighbourhood high street. Dulwich in SE21 and SE22 is the highest-value residential end of the borough with a small, valuable village retail pitch.
HM Land Registry recorded 2,253 open-market residential sales across Southwark in the twelve months to 29 May 2026 at a median of £526,500, down 4.3% on the year. That is the second lowest median of the seven central boroughs and by some distance the second highest transaction count, which tells you this is a working market rather than a trophy one. Detached stock ran at £1,787,500, semi-detached at £1,320,088, terraced at £881,250 and flats at £450,000. New build was 101 of 2,253 sales at a premium of minus 12%, one of only two negative new-build premiums in the sub-region. High volume at accessible prices is exactly the profile that supports semi-commercial and mixed-use lending.
Southwark planning data and the gap we will not paper over
Southwark does not publish a planning register we can read by machine. This page cites no applications, no counts and no approval rates, and neither does our Bankside and London Bridge page, which sits inside the borough. The temptation to borrow from Lambeth next door is obvious and we are not taking it, not least because two of the Lambeth applications in our own dataset are formal observations on Southwark schemes rather than Southwark decisions. What we can verify is that 2,253 open-market residential sales completed here at a £526,500 median in the twelve months to 29 May 2026, down 4.3%, and that four Opportunity Areas are designated inside the borough. On a specific SE postcode we check the council portal manually before submission.

Operators buying their own restaurant or bar use a trading business mortgage. Landlords with several SE titles consolidate through portfolio refinance at 6.5 to 8.0%. Commercial mortgages are unregulated lending outside the FCA's regulated mortgage perimeter, and we do not hold FCA authorisation because the products we arrange are unregulated.

Where lender appetite sits across Southwark
Southwark values sit at a level where blended-cover structures work cleanly, which puts the specialist lenders first in line here. Shawbrook and InterBay Commercial take most of our Peckham, Camberwell and Walworth semi-commercial at up to 75% LTV. Cynergy Bank and LendInvest take converted warehouse office and multi-unit mixed-use. Allica, Cambridge and Counties, Hampshire Trust, Paragon and Recognise cover mid-market Class E and portfolio cases. The well-let SE1 office and national-covenant retail end is where NatWest, Lloyds, Barclays and Santander compete at 60 to 65% LTV. Peckham and Bermondsey hospitality goes to the trading specialists at 60 to 70% LTV. The negative new-build premium of minus 12% is worth knowing before you buy a new commercial unit inside a residential-led scheme.
Property types we finance in Southwark
Asset classes most active in Southwark, each linked to the dedicated finance structure, lender appetite and typical terms for that property type.
Southwark commercial mortgage rates, fees and deposit
The commercial mortgage rates we are placing in Southwark at mid-2026 sit at 6.5 to 8.5% pa for the dominant local profile, which here is office and mixed-use investment. Expect loan to value of 65 to 75%, which puts the deposit or retained equity at roughly a quarter to a third of the value of the property. Owner-occupied business borrowing prices from 6.0 to 7.5% pa, commercial investment from 6.5 to 8.5% pa, and trading businesses from 7.0 to 9.0% pa. A commercial remortgage on an asset you already hold in SE1, SE5, SE15 and the surrounding outcodes runs 6.0 to 8.0% pa.
Costs beyond the rate are where Southwark deals are won or lost. Arrangement fees run 1.0 to 2.0% of the facility. Valuation fees start around £1,500 on a single unit and reach £8,000 or more on a multi-let London building, and the RICS Red Book valuation is the critical path on almost every case, so we instruct it in week one. Legal costs run £4,000 to £15,000. Stamp duty land tax applies at the non-residential rates. Check early repayment charges before you fix, because a five-year fix broken in year two is rarely the cheapest way to repay. Local pricing context: the median transaction in Southwark LPA is £526,500, which is residential data we use only as a temperature gauge for the surrounding market.
Bridging finance in Southwark, and when it is the right answer
Not every Southwark purchase fits a term facility on day one. An auction lot, a vacant unit that needs letting before a lender will price it, or a change-of-use scheme awaiting consent all point at commercial bridging first. Bridging loans run 8.5 to 11.0% pa, or 0.70 to 0.95% per month, over three to twenty-four months, and exit onto a commercial mortgage once the asset is income-producing. We only recommend bridging finance where the exit is genuinely identified and underwritten, because an unplanned bridge is the most expensive money in commercial finance. If the term lender will take the deal now, we will tell you to skip the bridge.
Which Southwark commercial mortgage lenders to approach
There is no single best lender for Southwark commercial property, only the right lender for this building on this week's credit appetite. High-street commercial lenders price keenest on prime business: Lloyds, NatWest, Barclays and Santander all compete where the covenant is strong. Challenger lenders such as Allica, Aldermore, Cambridge and Counties, OakNorth and Paragon take most of the SME and mid-market finance in SE1, SE5, SE15 and the surrounding outcodes. Specialist lenders, Shawbrook, InterBay Commercial, LendInvest, Cynergy Bank, Together and Hampshire Trust, cover the semi-commercial, multi-let and shorter-lease commercial finance the high street declines.
Comparing those finance options properly is the work. Most brokers send a deal to two lenders they know. We benchmark it across the panel, because the difference between the third-best and the best quote on a Southwark commercial property is usually worth more than every fee in the transaction combined. We arrange commercial mortgages, commercial remortgages, portfolio facilities, second charges and bridging loans. We do not arrange unsecured business loans, and we do not arrange buy-to-let mortgages on residential property, so if that is what your deal needs we will say so and point you elsewhere rather than waste a month finding out.
On eligibility, the property finance question we are asked most in Southwark is what a lender needs before it will commit. For owner-occupied business, two years of filed accounts is the usual minimum, though twelve to eighteen months places comfortably in well-understood sectors. For investment properties the eligibility test is about the tenant, the lease and the cover ratio rather than about you personally. Clean credit for the company and its directors matters throughout, and a full inspection rather than a desktop valuation is worth insisting on, because a thin report can cost five to ten percentage points of LTV. Send us the property market context you already have, the lease or the accounts, and we will tell you which lenders will look at it before you spend anything.
