2. Energy infrastructure shift
- Nuclear + low-carbon energy replacing older systems
3. Digital connectivity expansion
- Rural broadband equalising opportunity
4. Urban regeneration
- Cities rebuilt around transport hubs
Simple Summary
UK postcode regions are being transformed through:
- HS2 (national high-speed rail spine)
- Northern Powerhouse Rail (northern city network)
- Nuclear megaprojects (Sizewell C, Hinkley Point C)
