Caerphilly County Borough, Bwrdeistref Sirol Caerffili, lies in south-east Wales and straddles the old county line between Glamorgan and Monmouthshire. It borders Cardiff and Newport to the south, Torfaen and Blaenau Gwent to the east and north-east, Powys to the north and Merthyr Tydfil and Rhondda Cynon Taf to the west. Caerphilly is its main and largest town; Risca, Ystrad Mynach, Newbridge, Blackwood, Bargoed, New Tredegar, Rhymney and Bedwas complete the list of towns. The broad Rhymney Valley forms the north of the borough, with the Rhymney River flowing about thirty miles south before reaching the Bristol Channel.
We are a broker and never a lender. Any limited company in the Caerphilly borough that wants to purchase or remortgage the building it trades from can come to us. Our loans in the Rhymney Valley are secured on business premises rather than homes.
What premises finance do companies in the Rhymney Valley need?
Sitting directly north of Cardiff and west of Newport puts the southern part of the borough within easy reach of both cities, which suits firms that want lower occupancy costs than the capital while still serving it. Typical purchases are industrial and storage units, workshops, trade counters, and offices for professional and service businesses. Higher up the valley, in Bargoed, New Tredegar and Rhymney, properties tend to be smaller town-centre shops and older commercial buildings.
Lenders weigh each type on its own merits. A modern unit is usually the most straightforward. Older valley premises can be fine security if they are in good repair and in active use. A shop with a flat above is semi-commercial, and a building tied to one trade, such as a nursery or a care setting, is assessed partly on the business it supports. Our page on owner-occupier mortgages covers the lender's view in more depth.

A figure of 2.0x means the trade makes up twice the share of local businesses that it does across the UK.
Construction and building trades are the largest group in the Caerphilly area, at 15.8% of its 5,070 business units against 12.5% across the UK. Civil engineering contractors run at 1.8 times the national share, and manufacturing and engineering at 6.7%. Care is the other notable cluster: there are 135 residential care businesses, nearly two and a half times the UK rate.
Those two groups borrow very differently. A contractor buying a yard is a plain owner-occupier case judged on profit, while a care home is assessed on occupancy and fee income too, so the two arrive at a lender with quite different paperwork.
How much does a commercial property loan in Caerphilly, Wales cost to set up?
Caerphilly owner-occupiers can generally borrow 70 to 75% of the lower of price and valuation, stretching to 80% where the trading record is strong. Indicative pricing is 6.0 to 7.5% a year, over 5 to 25 years, with arrangement fees of 1 to 2%, subject to status, accounts and valuation. Valuation and legal fees are paid by the borrower.
The property tax is Wales's Land Transaction Tax. For commercial purchases the Welsh Revenue Authority sets bands of 0% to £225,000, 1% to £250,000, 5% to £1,000,000 and 6% above, rates as at October 2026 from gov.wales; check the current rates before you buy.
Illustrative example. An electrical contractor buys a unit in Ystrad Mynach for £320,000. With a 75% loan of £240,000, the deposit is £80,000. LTT is £3,750: £250 on the slice from £225,001 to £250,000 and £3,500 on the next £70,000. Total cash before fees is about £83,750. The full bands are in our guide to commercial stamp duty.

Should we rent or buy business premises in the Caerphilly borough?
Owning gives a company control over its building, protection from rent reviews and an asset on the balance sheet, but it ties up a deposit that could otherwise fund stock or staff. For many Rhymney Valley businesses the deciding factor is how long they expect to stay. A firm that has rented the same unit for a decade and plans to stay for another often finds the repayments close to the rent.
Buying from your landlord is common. The lender can see the business already trades successfully from the address, and the purchase avoids the cost of moving. Our guide on rent versus buy sets out the questions to ask.
Who looks after planning and the legal charge for an owner-occupier mortgage in Caerphilly County Borough?
Caerphilly County Borough Council is the planning authority for the area. The lender's solicitor checks the permitted use of the building, which matters where a former chapel, shop or industrial building has been converted. The security is a legal charge registered at HM Land Registry, because Wales is in the England and Wales jurisdiction, and the directors may be asked for a personal guarantee.
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. For neighbouring areas, see business mortgages across Wales.
Business mortgages in Caerphilly County Borough's towns
Caerphilly (Caerffili)
The main and largest town, in the south of the borough close to Cardiff. Its town centre has shops, offices and hospitality, and its edges hold industrial and trade units. Owner-occupiers here often serve the capital as well as the valley, which widens the pool of possible occupiers a valuer considers.
Blackwood
Blackwood is one of the larger towns in the middle of the borough. A busy high street with independent retailers, cafés and service businesses sits alongside smaller industrial units, and many local firms are long-term tenants weighing up buying their premises.
Ystrad Mynach
Ystrad Mynach lies in the Rhymney Valley and is one of the borough's central towns. Its premises include offices, workshops and trade units, and its position in the valley makes it a practical base for contractors and service firms covering the whole borough.
Bargoed
Bargoed sits further up the Rhymney Valley. Its commercial property is mostly town-centre retail and smaller older buildings, often with accommodation above, so semi-commercial lending is a frequent route for buyers here.
Risca
Risca is in the south-east of the borough, on the Monmouthshire side of the historic county line and close to Newport. Local trades, retailers and light industrial businesses make up its owner-occupier base, many serving customers across the Newport area.
Rhymney and New Tredegar
At the top of the valley, near where the Rhymney River rises, these towns have modest commercial property: shops, small workshops and community businesses. Values are often within the LTT nil-rate band, keeping tax low, though the lender's minimum loan size needs checking.
