Need Ethernet run in your home?

From one socket upstairs to finishing cable a builder left in the walls, we install and test home cabling across Berkshire, Surrey and West London.

[See our data cabling service](https://berkshirewifi.co.uk/data-cabling/)

A question we hear on the phone more than you might expect, usually from someone in a Maidenhead or Slough semi who has just been told a cable would fix the upstairs WiFi: is Ethernet free?

Once it is in, yes. Ethernet is not a subscription and it is not a broadband package. It is copper cable inside your house, running from a switch to a socket or an access point. You pay once to have it installed, and after that it costs nothing to use. Your internet still comes from your broadband provider. The cable just carries it around the house without the dropouts.

So the real question is what the installation costs. We do not publish a price list, because a two-point loft job in a Bracknell semi and a whole-house cabinet in a Sunningdale detached are different jobs. What we can do is explain what moves the quote, so the fixed figure we give after photos or a visit makes sense. The service is [data cabling](https://berkshirewifi.co.uk/data-cabling/), and if you are still deciding whether to wire at all, read [is it worth running Ethernet cable](https://berkshirewifi.co.uk/blog/is-it-worth-running-ethernet-cable/) first.

## What you are actually paying for

The cable itself is a small part of the bill. What you pay for is the route: getting from the cupboard where the broadband lands to each socket, access point or camera without making a mess, then proving every run works.

That breaks down into:

- **Planning the route** through the loft, voids, cupboards or outside walls

- **Pulling the cable** without damaging it or the house

- **Terminating** each end on a socket or patch panel

- **Testing and labelling** every run so you know what goes where

- **Making good** holes, trunking and faceplates

Labour and access decide the price. Two houses with the same number of points can be very different days.

## What moves the quote

These are the things we look at on every home cabling job.

- **Number of points.** Each run is its own pull, termination and test. More points cost more, but each extra point while the loft is open costs less than the first.

- **Floors.** A loft drop to a first floor bedroom is quick. Getting from the ground floor to a second floor needs a vertical route, usually through cupboards.

- **Loft and void access.** A boarded loft with a decent hatch is quick. Deep insulation, no boards or no loft at all slows things down.

- **Wall construction.** Solid brick is slower to drill and chase than plasterboard on studs. Many period houses have solid walls throughout.

- **Flush or surface finish.** A flush socket needs a back box and sometimes a chase. A surface box or neat trunking is quicker and easier to change later.

- **Cable grade.** Cat6 is our default. Cat6a costs more and is thicker and slower to terminate. [Cat5e vs Cat6 vs Cat6a](https://berkshirewifi.co.uk/blog/cat5e-vs-cat6-vs-cat6a-home/) explains when it is worth it.

- **Cabinet or patch panel.** A few runs can land on a small switch. Ten or more usually want a patch panel and a small cabinet.

- **Active kit.** A switch is part of the job, and it needs to be a PoE switch if it powers access points or cameras. Your provider’s router usually stays where it is.

- **Access point and camera drops.** Ceiling access points and outdoor cameras need their own runs, often to awkward spots. They are some of the most useful cables in the house. See [why wired access points matter](https://berkshirewifi.co.uk/blog/why-wired-access-points-matter/), and our guide to [whether home CCTV is worth it](https://berkshirewifi.co.uk/blog/is-cctv-worth-it-berkshire/) for camera drops.

- **Outbuildings.** A garden office or garage needs outdoor-rated cable and a route across the garden, sometimes in a duct or trench.

- **Testing.** Every run should be tested. That is part of the job, not an extra.

## The cheapest time to wire

The cheapest time to install Ethernet is when the walls, floors or ceilings are already open.

- **Renovations.** If you are rewiring, replastering or replacing floors, data cable goes in at first fix alongside the electrics. That is far quicker than a retrofit.

- **Extensions and loft conversions.** New rooms are often where WiFi struggles most, so cable them while the structure is open. See [WiFi not reaching an extension or loft conversion](https://berkshirewifi.co.uk/blog/wifi-not-reaching-extension-loft-conversion/).

- **New builds.** Before you move in, before carpets and furniture. Many new builds already have some cable that just needs terminating. [New build WiFi problems](https://berkshirewifi.co.uk/blog/new-build-home-wifi-problems-berkshire/) covers what to look for.

- **Before decorating.** If the decorator is booked for next month, cable this month.

The pattern is the same each time. The labour is in opening the route, so if someone else is already opening it, cable can go in alongside for much less effort.

## Retrofit without mess

Most homes we cable are finished and lived in. That is normal, and it rarely means chasing every wall.

Typical retrofit routes are loft drops into ceilings and down built-in cupboards, a rise from the under-stairs cupboard where the broadband lands, neat external runs along a side wall, and lifting a few boards where there is a suspended floor. [Adding Ethernet without ripping up the house](https://berkshirewifi.co.uk/blog/adding-ethernet-without-ripping-up-the-house/) shows how each route works.

Retrofit costs more than first fix, because the route has to be found rather than designed in. It usually costs less than people fear, because most houses have a loft or void that does the heavy lifting.

## Typical job shapes

Most home cabling jobs fall into one of four shapes. Knowing which one you are is the first step to a sensible quote.

### Access point backbone only

Two or three Cat6 runs from the router cupboard to ceiling access points, one per floor. No wall sockets. This is the smallest job that fixes whole-house WiFi properly, and it is often done in a day.

### Home office, TV and access points

The access point runs, plus a socket at the desk and one behind the main TV. This is the shape we install most. You get a solid connection where you work and watch, and strong WiFi everywhere else. Our [room by room guide to Ethernet points](https://berkshirewifi.co.uk/blog/how-many-ethernet-points-room-by-room/) helps you decide which rooms belong on the list.

### Whole house with a cabinet

Points in most rooms, access points on every floor, camera drops, and a small cabinet with a patch panel and switch. This is usually a renovation or a larger house, and it takes longer because of the run count and the cabinet work.

### Garden office run

One outdoor-rated run from the house to a garden office or outbuilding, usually with an access point inside. The cost is mostly the route across the garden: along a fence, through a duct, or in a shallow trench. [How to get internet to a garden office](https://berkshirewifi.co.uk/blog/how-to-get-internet-to-a-garden-office-without-dropouts/) explains the options.

## Town patterns

House type changes the route more than anything, and house type tends to follow the town.

- ** [Slough](https://berkshirewifi.co.uk/data-cabling-slough/) and [Bracknell](https://berkshirewifi.co.uk/data-cabling-bracknell/):** estate semis and townhouses with accessible lofts. Usually quick loft drops. Three storey townhouses need a vertical route through cupboards.

- ** [Windsor](https://berkshirewifi.co.uk/data-cabling-windsor/) and [Maidenhead](https://berkshirewifi.co.uk/data-cabling-maidenhead/):** period brick, solid walls, tight eaves and some conservation streets. Slower drilling and more care with finishes on the street side.

- ** [Ascot](https://berkshirewifi.co.uk/data-cabling-ascot/), [Virginia Water](https://berkshirewifi.co.uk/data-cabling-virginia-water/) and [Sunningdale](https://berkshirewifi.co.uk/data-cabling-sunningdale/):** larger houses with long runs, garages, annexes and garden buildings. More runs, longer distances and outdoor cable.

- ** [Reading](https://berkshirewifi.co.uk/data-cabling-reading/) and [Woking](https://berkshirewifi.co.uk/data-cabling-woking/):** Victorian terraces with no easy loft route alongside newer family homes with simple lofts.

We cover the rest of [Berkshire](https://berkshirewifi.co.uk/areas/berkshire/) as well, and the same patterns usually apply.

## Cheap versus right

There are cheaper ways to get cable into a house. Two are worth watching for.

**Copper-clad aluminium cable.** Some cable sold as Cat5e or Cat6 has an aluminium core with a thin copper coating, known as CCA. The cabling standards behind those category labels call for solid copper conductors, so CCA does not meet them, whatever the box says. Fluke Networks, which makes the testers installers use, notes that aluminium has about 55% higher resistance than copper of the same size. That means more heat and voltage drop on the PoE runs that power access points and cameras, and the conductors are more brittle at terminations.

**Untested points.** A socket that shows a link light is not the same as a run that passes a test. Poor terminations cause slow speeds and intermittent dropouts that are very hard to trace later. Ask whether every run will be tested and labelled.

A cheap install that has to be redone is the most expensive option. We use solid copper Cat6, test every run and label both ends.

## Getting a fixed quote

To give you a fixed price, we need to understand the route. Send us:

- A list of the rooms and devices you want cabled

- Photos of the loft hatch and the inside of the loft

- A photo of where the broadband comes in

- A floor plan or rough sketch, if you have one

- Any renovation or decorating plans, with dates

From photos we can often quote straight away. Larger houses, outbuildings and anything unusual get a short visit first. Either way, the quote is fixed before we start.

If you are comparing quotes, check each one says how many runs and to where, the cable grade and that it is solid copper, flush or surface finish, what sits at the router end, whether every run is tested and labelled, and who makes good afterwards. A single figure with none of that is hard to compare.

FAQs

## Frequently Asked Questions

### Is Ethernet free once it is installed?

Yes. Ethernet is a one-off installation, not a subscription, and it is not tied to your broadband provider. Once the cable is in, it costs nothing to use. The only running cost is the small amount of power a network switch draws. [Data cabling](https://berkshirewifi.co.uk/data-cabling/).

### What drives the cost of wiring one room?

Mainly the route. A bedroom under a boarded loft is quick. A ground floor room in a solid-walled house, two floors from the router, takes longer. Flush sockets and long runs add time. [How many Ethernet points you need](https://berkshirewifi.co.uk/blog/how-many-ethernet-points-room-by-room/).

### Is it cheaper to wire during a renovation?

Yes. With walls, floors and ceilings open, cable goes in at first fix with far less labour than a retrofit. Tell us before the plasterer is booked. [WiFi not reaching an extension or loft conversion](https://berkshirewifi.co.uk/blog/wifi-not-reaching-extension-loft-conversion/).

### Does Cat6 or Cat6a change the price?

A little. Cat6a cable and connectors cost more, and the thicker cable is slower to pull and terminate. For most homes Cat6 is the right choice. [Cat5e vs Cat6 vs Cat6a](https://berkshirewifi.co.uk/blog/cat5e-vs-cat6-vs-cat6a-home/).

### Can you run cable without damaging walls?

Usually. Lofts, built-in cupboards, floor voids and neat external runs cover most houses. We only chase a wall if there is no other route and you agree to it first. [Adding Ethernet without ripping up the house](https://berkshirewifi.co.uk/blog/adding-ethernet-without-ripping-up-the-house/).

### Do I need a cabinet or patch panel?

For a handful of runs, a small switch next to the router is enough. Once you pass about ten runs, or add cameras, a patch panel in a small cabinet keeps the cupboard tidy and easy to change. [Data cabling](https://berkshirewifi.co.uk/data-cabling/).

### Are wired access points better than more mesh nodes?

In larger or thick-walled homes, usually yes. Each wired access point gets full speed from its cable, so there is no wireless hop losing speed between nodes. Mesh is still fine in many smaller homes. [Why wired access points matter](https://berkshirewifi.co.uk/blog/why-wired-access-points-matter/).

### Do you install data cabling in Maidenhead, Slough and Ascot?

Yes. We cable homes in [Maidenhead](https://berkshirewifi.co.uk/data-cabling-maidenhead/), [Slough](https://berkshirewifi.co.uk/data-cabling-slough/), [Ascot](https://berkshirewifi.co.uk/data-cabling-ascot/) and across [Berkshire](https://berkshirewifi.co.uk/areas/berkshire/).
