Portsmouth is a port city and unitary authority in Hampshire, built mostly on Portsea Island in the Solent, which makes it the only English city not located primarily on the mainland. With a population last recorded at 208,100 it is the most densely populated city in the United Kingdom. It has held a Royal Navy dockyard and base for centuries, gained city status in 1926 and forms part of the South Hampshire urban area with Gosport, Fareham, Havant, Eastleigh and Southampton.
We are a broker, not a lender. We arrange business mortgages for limited companies buying or refinancing the premises they occupy in Portsmouth. This is finance secured on a trading company's own commercial building, not a residential mortgage, and we take each case to the lenders whose criteria fit.
Who buys premises in the City of Portsmouth with an owner-occupier mortgage?
Defence is the city's biggest industry. Ten per cent of the workforce is employed at Portsmouth Naval Dockyard, and BAE Systems Surface Ships has its headquarters here. Around the base sit engineering, electronics, fabrication and maintenance suppliers that need secure workshops and offices. IBM's UK headquarters is in the city too, and Portsmouth was Zurich Financial Services' UK headquarters until 2007, which shows the depth of office-based employment.
Retail and leisure add a second buyer group. City shopping on Commercial Road and in the Cascades Shopping Centre, Gunwharf Quays on the former HMS Vernon site, the Historic Dockyard and Ocean Retail Park all draw trade, and a fishing fleet of 20 to 30 boats lands its catch at Camber Quay. Restaurants, shops and food businesses buying freeholds in the older streets often find flats above, which our semi-commercial finance page explains.

A figure of 2.0x means the trade makes up twice the share of local businesses that it does across the UK.
Portsmouth's 7,720 business units are dominated by construction, at 17.2% of firms against 12.6% across the UK, and specialist trades such as electricians, plumbers and roofers run at 1.53 times the national rate. Restaurants, cafes and pubs are well above average at 9.8%, and betting shops at 1.94 times. On a tightly built island city, a trade firm that owns its yard or workshop avoids competing for scarce space at every lease renewal. Bars and bookmakers buying freeholds are underwritten on trading figures.
How does island geography affect commercial property finance in Portsmouth, England?
Portsea Island is separated from the mainland by Portsbridge Creek, crossed by the M275, the A3 and the A2030, a railway bridge and two footbridges. Most of the island is less than 3 metres above sea level. Those two facts shape every deal: commercial land on the island is scarce, which supports demand for existing buildings, and a lender's solicitor will review flood searches and insurance with care.
The sea is also the city's link to trade. Portsmouth International Port serves Caen, Cherbourg-Octeville, St Malo, Le Havre, Santander, Bilbao and the Channel Islands, with services by Brittany Ferries and DFDS Seaways. Hovertravel runs from Southsea to Ryde. Freight, haulage and travel businesses buying near the port value that access, and a valuer will count it in a unit's favour when judging how easily it would relet.

Portsmouth's shop count has not moved, 2,020 in 2016 and 2,020 in 2026, while industrial units rose 13.2% to 1,460 and offices 15%. Other property, which includes leisure and hospitality buildings, grew 22.5%. Industrial units average £40,300 in rateable value, the highest of the main types, so a workshop buyer here should expect a larger loan than the shop or office figures suggest.
What deposit and SDLT should I budget for a business property loan in Portsmouth, UK?
Lenders active in owner-occupier lending usually advance 70 to 75% of the purchase price, up to 80% for strong cases, at indicative rates of 6.0 to 7.5% a year, over 5 to 25 years, with arrangement fees of 1 to 2%, all subject to status, accounts and valuation. SDLT is charged at 0% up to £150,000, 2% from £150,001 to £250,000 and 5% above £250,000 (HMRC non-residential rates as at October 2026; check the current rates before you buy).
Illustrative example. A defence electronics supplier buys a workshop for £400,000. A 75% loan is £300,000, the deposit £100,000 and SDLT £9,500, so the company needs £109,500 in cash before legal and valuation fees.
Commercial lending to a limited company is unregulated and falls outside the FCA's regulated mortgage perimeter; where a deal would be regulated, for example lending to a sole trader or individual, or a property where the borrower or a close family member will live in part of it, we refer it to an appropriately authorised firm. Our stamp duty guide and the Hampshire business mortgages page cover more.
Portsmouth districts where companies buy premises
Old Portsmouth and Camber Quay
The original town in the south-west of the island, including Portsmouth Point, known as Spice Island. Camber Quay hosts the fishing fleet and its quayside fish market, so seafood wholesalers, marine trades, pubs and restaurants are typical owner-occupiers, often in older buildings with heritage points to check.
Gunwharf Quays
The repurposed HMS Vernon shore establishment, now stores, restaurants and a cinema, with development continuing until 2007. Leisure and retail businesses operate here, and premises are usually held within a managed estate, so the lender will read the lease and service charge terms closely.
Commercial Road and the Cascades
The city's main shopping area, centred on the 1980s Cascades Shopping Centre, which draws 185,000 to 230,000 visitors weekly. Independent retailers, cafés and service businesses buy freehold shops nearby, often with upper floors that make the property semi-commercial.
Ocean Retail Park
Built in September 1985 on the north-eastern side of Portsea Island, on the site of a former metal-box factory. Trade counters, retail warehouses and service businesses near here benefit from road access off the island towards the mainland.
Southsea
The seafront district in the south of the island, where Hovertravel runs to Ryde from near Clarence Pier. Hotels, cafés, shops and leisure businesses make up most of the commercial stock, and lenders price hospitality on trading figures as well as bricks and mortar.
Cosham
On the mainland side of Portsbridge Creek, Cosham is where IBM has its UK headquarters. Offices, local shops and service premises here suit companies that want easier road access than the island offers.
