Business Mortgages Broker is a commercial mortgage broker, not a lender, founded by Matt Lenzie, who has 25 years in financial services, raising debt and equity. We arrange business mortgages for trading companies across South East England, from Milton Keynes to the Isle of Wight and from Oxford to Dover, that want to buy, or refinance, the premises they trade from.

South East England is the most populous English region, with 9,691,844 people in 2025, and has the largest economy of any UK region after London. That economy is not even. GDP per capita in Berkshire and Milton Keynes is more than twice that of East Sussex and the Isle of Wight, so a business park office near Reading and a seafront guest house in Hastings are very different lending propositions. This page covers both ends. It is finance for a trading business's premises, not a residential mortgage; the tax and legal rules that apply across the country are on our page on business mortgages in England.

Which premises do companies along the M3, M4 and Gatwick Diamond buy in SE England?

Many high technology companies are located near the M3 in Surrey and the M4 in Berkshire, and Microsoft and Oracle have UK headquarters in Reading (Wokingham borough). The Gatwick Diamond is a hub for hi-tech industry centred on Gatwick Airport, the UK's second busiest airport.

The global names rent. Around them sit the smaller owner-occupiers: IT, engineering and consultancy firms buying offices on business parks, laboratory and research businesses near Oxford, and distribution, aviation-support and trade businesses in industrial and logistics units close to the motorways and the airport. Business park units are usually modern and well evidenced by comparable sales, which helps the valuation. Specialist laboratory fit-outs need more explanation, because the valuer will consider how readily another occupier could use the building.

How do coastal towns and ports in South-East England change the lending picture?

The region's long coastline runs from the Solent through Brighton to Kent's Channel ports and the White Cliffs of Dover. Southampton and Portsmouth are major port cities, and coastal towns support a visitor economy of hotels, guest houses, pubs, cafes and attractions.

Lenders price these as trading businesses, at typically 7.0 to 9.0% a year, indicative, subject to status, accounts and valuation, because the value of the building is tied to the trade. Seasonal income needs explaining in the accounts. High-street shops with flats above, common in the coastal towns, are semi-commercial: our page on semi-commercial premises covers how they are assessed, at indicative rates of 6.5 to 8.5% a year and up to 75% loan to value.

Buying or refinancing: premises finance options in Southeast England

Buying

For an owner-occupier purchase, lenders typically advance 70 to 75% of the price or valuation, up to 80% for strong cases, at indicative rates of 6.0 to 7.5% a year, over 5 to 25 years (some to 30), with arrangement fees typically 1 to 2%. Where a purchase must complete quickly, for example at auction or before a lease break, bridging finance for business premises at an indicative 0.70 to 0.95% a month can complete first.

Refinancing

Many companies in the region have owned their buildings for years. Remortgaging business premises can release equity for expansion, consolidate borrowing or move off a lender's variable rate, at indicative rates of 6.0 to 8.0% a year.

What does a purchase in the South East (UK) cost beyond the deposit?

Premises in South East England are taxed under Stamp Duty Land Tax at the non-residential rates: 0% up to £150,000, 2% from £150,001 to £250,000 and 5% above £250,000 (HMRC, gov.uk; rates as at October 2026; check the current rates before you buy). Illustrative example. On a £500,000 freehold unit with no VAT, SDLT is £14,500. If the seller has opted to tax, VAT at 20% is added to the price and SDLT is worked out on the VAT-inclusive figure. Our commercial stamp duty guide covers leases and VAT.

Lenders do not lend the tax, legal fees or valuation fees, so they come from the business's own funds with the deposit. 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.

How we arrange business mortgages across the South East England region

We read the accounts, the building and the timetable, then go to the market: high-street banks and specialist lenders whose criteria fit the business and the property. We prepare the case, brief the valuer and keep your solicitor and the lender working to the same date. For premises inside the M25, see our page on business mortgages in London. We are not tax or legal advisers, so your solicitor confirms the SDLT and the title.

Cities and towns across the South East where companies buy premises

  • Brighton and Hove

    The region's largest city, with a population of 290,885 (2019), in East Sussex. Its business base leans to digital and creative firms, hospitality, independent retail and professional practices. Shops and restaurants with flats above are common on its busy streets, which makes semi-commercial finance a regular part of the market here.

  • Milton Keynes

    Population 269,457 (2019), in Buckinghamshire, with GDP per capita among the highest in the region. A planned new town with modern office campuses and large distribution and logistics units close to the M1, it suits companies buying standard, well-evidenced buildings that valuers can assess with confidence.

  • Southampton

    Population 252,520 (2019), at the centre of the South Hampshire conurbation of 855,569. The port drives logistics, marine engineering and trade businesses that buy warehouses and industrial units, while the city centre supports offices, retail, hospitality and the professional practices that serve the wider area.

  • Portsmouth

    Population 214,905 (2019) and home of HMS Victory. A naval and port city, Portsmouth has engineering, marine and defence-linked businesses on its industrial estates, alongside the hospitality and visitor trade around the historic dockyard and seafront, and retail and practices in the city centre.

  • Reading

    Population 161,780 (2019), with Microsoft and Oracle UK headquarters nearby in Wokingham borough. Reading is the heart of the Thames Valley technology economy, so offices for IT, software and consultancy businesses form a large share of owner-occupier purchases, alongside trade and logistics units on the M4.

  • Oxford

    Population 152,457 (2019), home to the University of Oxford. Research, life sciences and technology spin-outs work alongside publishing, professional services, hospitality and retail. Laboratory and specialist premises need careful valuation, while practices and offices in the city follow the usual owner-occupier pattern.

  • Slough

    Population 164,455 (2019), in Berkshire. Slough's large trading estate, close to Heathrow and the M4, houses manufacturing, distribution, data and service businesses, and companies there often buy industrial and warehouse units that have long served the same kind of occupier.

  • Crawley

    Population 112,409 (2019), home to Gatwick Airport and the Gatwick Diamond. Aviation, logistics, engineering and technology firms occupy its business parks and industrial estates, and owner-occupiers range from airport-linked service businesses to manufacturers, trade counters and the professional practices that serve the town.

FAQ

Business mortgages in South East England: questions

Do lenders treat premises in Kent differently from premises in Berkshire?

The rules are the same, but the valuation reflects local demand and comparable evidence. A modern unit in a busy business park is usually easier to value than a specialist or seasonal building, which can affect how much a lender will advance.

How much deposit do I need to buy premises in the South East?

Usually 25 to 30% of the price, as lenders typically lend 70 to 75%, up to 80% for strong cases. Add SDLT, legal and valuation fees and an arrangement fee of typically 1 to 2%.

Can I get a commercial mortgage for a seaside hotel or guest house?

Yes, as a trading business mortgage. Lenders look at the trading accounts, occupancy and seasonality as well as the building. Indicative rates are 7.0 to 9.0% a year, subject to status, accounts and valuation.

Can I refinance premises I already own to fund expansion?

Yes. A commercial remortgage can release equity from a building the company owns, at indicative rates of 6.0 to 8.0% a year. The lender will want to see that the business can service the larger loan.
