Cat6 data points and whole-home WiFi installation
Data, Network and WiFi Cabling
Data, network and WiFi cabling covers installing wired Cat6 data points around a property and fitting mesh WiFi systems to extend reliable wireless coverage, particularly useful in larger or older properties where a single router struggles to reach every room.
Definition
What Data & Network Cabling covers
A structured cabling installation runs Cat6 (or better) cable from a central point to data outlets in each room, giving a faster and more reliable connection than WiFi alone for fixed devices such as TVs, computers and smart home hubs. Mesh WiFi systems use multiple linked access points to extend wireless coverage evenly through a property, often combined with a wired backbone for the best performance.
Suitable for
- Home offices and media rooms needing a reliable wired connection
- Larger or period properties with poor WiFi coverage in some rooms
- New builds and renovations where cabling can be first-fixed before walls are closed up
- Households wanting whole-home mesh WiFi rather than a single router
Not suitable for
- Internet service provision itself — this is arranged separately with your broadband provider; we install the in-home cabling and network hardware
- Enterprise-grade networking beyond typical domestic or small business requirements
Process
How the work is carried out
- 01
Assessment
Reviewing the property layout, existing router position and where reliable connectivity is needed.
- 02
Design
Planning data point positions, cable routes and mesh WiFi access point locations.
- 03
Installation
Running cabling and fitting outlets, or positioning and configuring mesh WiFi units.
- 04
Testing
Testing each point and confirming coverage before handover.
Typical timescale
A small number of data points or a mesh WiFi installation is typically completed within a day; whole-house structured cabling as part of a renovation takes longer and is coordinated with other first-fix trades.
Cost guidance
Data and network cabling typically costs £80–£250 per point or per job in our area, with a single data point toward the lower end and a mesh WiFi installation or multi-room cabling job priced as a whole. We provide an itemised quotation after assessment rather than a fixed headline price.
Limitations and exclusions
- Broadband contracts and internet service itself are arranged separately with your chosen provider
- Cabling as part of a renovation is best planned at first-fix stage, before walls and floors are closed up, to avoid retrofit disruption
- Network hardware (routers, mesh units, switches) is supplied to an agreed specification unless a supply-and-fit package is agreed

FAQs
Data & Network Cabling FAQs
Is mesh WiFi better than a single router?
For larger or period properties with thick walls, mesh WiFi often gives more even coverage than trying to boost a single router. We assess the property and advise on the right approach for your layout.
Should I get data cabling done before or after decorating?
Ideally before, at first-fix stage, so cable can be run through walls and floors without disruption. Retrofit installation is possible but tends to involve more visible cabling or surface trunking.
Can you improve WiFi in a property with thick period walls?
Generally yes, usually with mesh access points and, where useful, a wired backbone between them. The right solution depends on the layout, which we assess on site.
