Hertfordshire is a ceremonial county in the East of England, lying directly north of London between Buckinghamshire and Essex. Wikipedia gives it an estimated population of 1,236,191 in 2024. Watford, in the south-west, is the largest settlement; Stevenage sits in the north, the city of St Albans in the centre and Hemel Hempstead in the west. Rather than one dominant city, the county is a spread of mid-sized towns, two of them born from planning experiments: Letchworth, the prototype garden city since 1903, and Stevenage, the first town to expand under the New Towns Act 1946. Services are now the largest part of its economy.
We are a broker, not a lender. We arrange business mortgages for limited companies that want to buy or refinance the building they trade from anywhere in Hertfordshire, from offices near Watford Junction to light industrial units beside the A1(M). This is commercial finance secured on a trading company's own premises, not a residential mortgage.
Which buildings do Hertfordshire companies buy with premises finance?
The county's large employers show how mixed its commercial stock is. MBDA develops missiles in Stevenage, where the Defence and Space division of Airbus also produces satellites. The old de Havilland site at Hatfield, where the Comet jet liner was developed, is now a business park and University of Hertfordshire campus hosting EE, Computacenter and Ocado. Welwyn Garden City holds Tesco's UK base, a Cereal Partners factory and Roche UK's headquarters, and GlaxoSmithKline has plants in Ware and Stevenage. Warner Bros. runs its main UK studio at Leavesden.
Behind those names is a deep layer of smaller trading companies: engineering subcontractors, laboratory and life-science suppliers, IT and professional firms, trade counters, caterers and independent retailers. When they buy, the purchase is usually an office suite or small office building, a light industrial or trade unit, a workshop with mezzanine storage, or a shop on a market-town high street. Our page on owner-occupier mortgages explains how lenders assess a company buying the building it occupies.

A figure of 2.0x means the trade makes up twice the share of local businesses that it does across the UK.
Across all ten Hertfordshire councils there are 70,340 business units, and the county leans heavily towards professional and creative work. Professional, scientific and technical firms make up 17.1% of businesses, against 13.9% nationally, and film, TV and music production runs at 1.72 times the UK share, with 1,375 firms. Head offices and management consultancies reach 1.43 times.
Hertfordshire is also a builders' county, with construction at 15% of firms. For an office-based company, buying a suite here usually means a larger loan than elsewhere in the region, given local values.
How do the M25, the A1(M) and four main lines shape an owner-occupier mortgage in Hertfordshire, UK?
As a home county inside the London commuter belt, Hertfordshire is crossed by the A1, A1(M), A41, A414, M1, M11 and M25. Four national railway lines run through it: the West Coast Main Line via Watford Junction, the East Coast Main Line via Stevenage, the Midland Main Line carrying Thameslink, and the West Anglia Main Line out of Liverpool Street in the east. A significant minority of people in every district commute to Central London.
For a buyer that has two consequences. Premises near a station or motorway junction tend to suit a wide pool of future occupiers, which a lender's valuer takes into account. And much of the undeveloped land is Metropolitan green belt, so new commercial sites are scarce. If the property is a shop with a flat above, our guide to semi-commercial premises covers how lenders treat the mixed use.

Total rated premises across the county grew only 3.9% to 34,060, and shops fell 1.4%. Industrial units grew most, up 7.6% to 9,050, with a high average rateable value of £53,400. Offices averaged £32,700. Limited new supply near London keeps demand firm for well-located units, which a valuer will reflect when comparing a building with recent local deals.
What does a commercial property loan in the Hertfordshire area cost before completion?
Lenders active in owner-occupier lending typically advance 70 to 75% of the purchase price or valuation, whichever is lower, rising to 80% for strong cases. Indicative pricing is 6.0 to 7.5% a year over terms of 5 to 25 years, with arrangement fees usually 1 to 2%, all indicative, subject to status, accounts and valuation. The deposit, the tax and the professional fees come from the business.
Hertfordshire is in England, so Stamp Duty Land Tax applies. HMRC's non-residential rates are 0% on the first £150,000, 2% from £150,001 to £250,000 and 5% above £250,000 (source: gov.uk; rates as at October 2026; check the current rates before you buy).
Illustrative example. An IT services company buys a freehold office building near Hatfield for £800,000. A 75% loan is £600,000, so the deposit is £200,000. SDLT on £800,000 comes to £29,500, taking the cash needed to about £229,500 before legal and valuation costs. Our guide to commercial stamp duty works through each band.
Who deals with planning and security for business property finance in the County of Hertford?
For local government purposes Hertfordshire is a non-metropolitan county with ten districts, and planning decisions sit with the district or borough council where the building stands, such as the Borough of Watford or East Hertfordshire. A lender's solicitor checks the planning history and confirms that the current use is lawful before releasing funds, so having that record ready early saves time.
The lender takes a first legal charge over the property, registered at HM Land Registry, and often a debenture or directors' guarantees as well. 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.

Business premises finance in Hertfordshire's towns
Watford
The county's largest settlement sits on the River Colne in the south-west. Head offices and UK bases gather here, from J D Wetherspoon and Camelot Group to Hilton Worldwide, TK Maxx and Costco. Smaller firms buy offices within reach of Watford Junction and the M1 and M25 junctions, while hospitality and retail businesses look at freeholds around the town centre.
St Albans
A cathedral city in the middle of the county, St Albans grew as the first major town on Watling Street, the Roman road north. The National Pharmacy Association, the trade body for UK pharmacies, is based here. Owner-occupiers tend to be professional practices, pharmacies, clinics and independent shops buying period offices and retail units in the centre.
Stevenage
In 1946 Stevenage became the first town expanded under the New Towns Act. It lies beside the A1(M) on the East Coast Main Line, and MBDA, Airbus and GlaxoSmithKline all work here. Their supply chains create steady demand for clean engineering units, laboratory space and modern offices that a company can buy outright.
Hemel Hempstead
An old market town rebuilt as a post-war New Town, Hemel Hempstead is in the west of the county on the West Coast Main Line and the A41. Dixons Carphone has large premises here. Distribution, trade and service businesses buy warehouses and industrial units close to the motorways, and retailers look at the town centre.
Hatfield and Welwyn Garden City
Hatfield's former de Havilland site is now a business park and university campus where EE, Computacenter and Ocado operate. Welwyn Garden City next door hosts Tesco's UK base, Roche UK's headquarters and a Cereal Partners factory. Technology, pharmaceutical and food-supply firms here are typical buyers of modern offices and business units.
Hertford and Ware
These historic towns sit along the River Lea in East Hertfordshire, the least densely populated district at the 2011 census. GlaxoSmithKline has a plant in Ware. The purchases we see here are often market-town shops, offices above them and smaller workshops used by local trading businesses.
Letchworth
Letchworth, in the far north, has served as the prototype garden city since 1903. Small manufacturers, workshops and trade suppliers buy units here within reach of the A1(M) and Stevenage, while independent retailers and service firms look at shops and offices in its planned town centre.
Rickmansworth and Kings Langley
Skanska is based at Rickmansworth, and Kings Langley has the plant-office of Pure, which makes DAB digital radios. Both lie in the south-west near the M25 and Watford. Construction, engineering and electronics firms in this corner of the county buy offices, small industrial buildings and yards.
