The Martin Group, a company based in Derry, Northern Ireland, has purchased NCP, the well-known car park operator, after it fell into administration. The deal transforms the firm into one of the UK's largest car park operators, adding hundreds of sites to its portfolio. NCP manages spaces at railway stations, airports, and city centres across the country, and the acquisition secures the future of these facilities. The purchase price was not disclosed, but it includes a network that serves millions of motorists each year.
For drivers and businesses that depend on NCP spaces, the change in ownership is not expected to cause immediate disruption. However, it marks a significant shift in the parking industry, placing a Northern Irish firm at the heart of the UK's urban infrastructure. The move also raises questions about how the new owner will manage parking in the country's biggest built-up areas, where demand is consistently high.
Birmingham tops built-up area ranking

| Town | County | Built-up area |
|---|---|---|
| Birmingham | West Midlands | 219.1 km² |
| Glasgow | Glasgow City | 138.1 km² |
| Leeds | West Yorkshire | 118.9 km² |
| Sheffield | South Yorkshire | 113.7 km² |
| Liverpool | Merseyside | 109.4 km² |
| Edinburgh | City of Edinburgh | 101.5 km² |
| Bromley | Greater London | 80.3 km² |
| Coventry | West Midlands | 77.7 km² |
| Hillingdon | Greater London | 76.4 km² |
| Manchester | Greater Manchester | 74.8 km² |
Birmingham, in the West Midlands, leads the ranking of built-up areas by sise, covering 219.1 square kilometres. This vast urban footprint makes it a prime location for car park operators. The city's extensive built-up area encompasses a mix of residential, commercial, and industrial zones, all generating steady parking demand. NCP has long maintained a strong presence here, with facilities near major transport hubs and shopping districts. Under the Martin Group's ownership, these sites will continue to serve the thousands of drivers who navigate Birmingham's streets each day.
What large built-up areas mean for car park businesses
The data highlights why towns like Birmingham are so important to operators. A larger built-up area typically means more roads, more vehicles, and a greater need for parking. The Martin Group's expanded network now includes locations in some of the UK's most sprawling urban centres, giving it a foothold in markets with consistent demand. While the table shows Birmingham at the top with 219.1 square kilometres, other large towns in the ranking also represent key revenue opportunities for the newly enlarged company.
Managing car parks in such areas comes with challenges, including congestion, competition from public transport, and the push for greener travel. The Martin Group will need to balance these factors as it integrates NCP's operations. For now, the acquisition ensures that one of the UK's most recognisable parking brands remains operational, with a focus on serving the dense urban cores that data shows are the country's largest.
