Network Switch Setup Guide UK¶
How to choose, install, and configure a network switch for UK home networks, covering unmanaged vs managed switches, PoE, VLANs, and placement in structured cabling setups.
Unmanaged vs Managed Switches for UK Homes¶
A network switch expands the number of wired ports in your home network beyond the four LAN ports on a typical BT or Sky router. For most UK homes, an unmanaged Gigabit switch is sufficient - models like the TP-Link TL-SG108 (£25) or Netgear GS308 (£30) offer 8 ports and require zero configuration. Managed switches (e.g. TP-Link TL-SG108E, £40, or Ubiquiti Switch 8 PoE, £110) add VLAN support, port mirroring, and QoS priority. These are useful if you segment your home network (IoT devices on VLAN 10, guest WiFi on VLAN 20, trusted devices on VLAN 30). Ofcom data shows 34 % of UK homes now have 10+ wired devices, making an 8-port switch the minimum recommended size.
Installation, PoE, and VLAN Configuration¶
Place the switch near your router or patch panel, plug in power, and connect using a Cat6 patch lead from a LAN port on the router to any port on the switch. All other ports are now live - connect your PC, TV, game console, and any Power over Ethernet (PoE) devices. If you have PoE devices (Ubiquiti access points, IP cameras, doorbells), choose a PoE+ switch that delivers 30 W per port. For VLAN configuration on a managed switch, access the web interface (usually 192.168.0.1 or a dedicated management IP), create your VLANs, and set the router's LAN port as a trunk (tagged) port carrying all VLANs. Budget £25-£150 depending on port count and features. Fanless models are recommended for quiet home office environments.
Specifications and Comparison¶
| Switch Model | Ports | Type | PoE | VLAN | UK Price |

| TP-Link TL-SG108E | 8 | Smart Managed | No | Yes | £40 |
| Netgear GS308 | 8 | Unmanaged | No | No | £30 |
| Ubiquiti Switch 8 PoE | 8 | Managed | PoE+ (4 ports) | Yes | £110 |
| TP-Link TL-SG1218MPE | 16 | Smart Managed | PoE+ (16 ports) | Yes | £150 |
| Netgear GS316PP | 16 | Unmanaged | PoE+ (16 ports) | No | £140 |
FAQ¶
- Do I need a managed switch for my UK home network?
- Only if you plan to use VLANs for network segmentation (e.g. separating IoT devices from your main PCs) or need PoE for IP cameras or access points. For basic port expansion, an unmanaged switch is simpler and cheaper.
- Can I connect multiple switches in my UK home network?
- Yes - you can daisy-chain switches using any port. Each hop adds under 1 ms latency, so two switches in a typical home network have no noticeable impact. Use a 16-port main switch and 5-port secondary switches in media rooms.
- What is PoE and do I need it?
- Power over Ethernet delivers electricity through the data cable, eliminating separate power adapters for devices like wireless access points and IP cameras. If you use Ubiquiti UniFi APs or a video doorbell, a PoE+ switch is recommended.
- Should I get a fanless network switch for home?
- Yes - fanless switches are silent and consume less power (2-5 W). Models like TP-Link TL-SG108 and Netgear GS308 are completely silent. Avoid rack-mount switches with fans unless your equipment is in a garage or loft.
- How many ports do I need in a UK home switch?
- Count your wired devices: router (1), PC (1-2), TV (1-2), game console (1-2), access point (1), printer (1). For most UK homes, 8 ports is the minimum, 16 ports provides comfortable headroom for future expansion.
- Does a network switch slow down my internet speed?
- No - a Gigabit switch supports 1 Gbps on every port simultaneously (non-blocking throughput). For FTTP up to 1 Gbps, a switch will not bottleneck. Motherboards with 2.5 GbE ports benefit from 2.5 GbE switches like the TP-Link TL-SG105-M2 (£80). For more information see our Ethernet Cable Installation Guide UK.
