Wi-Fi is one of the first things a guest looks for and one of the most common things they mention in a review when it is missing. The problem is that a fixed line does not fit how short lets work. Install dates run to weeks, contracts run to years, and between one booking and the next you may not want a line at all. A 5G connection sidesteps most of that, and for a lot of properties it is now the better answer rather than the fallback.
The 30-second version
- Guests expect Wi-Fi and will mention it in reviews. It is not a luxury on a listing any more.
- A 5G router can be live the day it arrives, against weeks for a fixed line install.
- No engineer visit and no hole in the wall, which matters if you do not own the building or it is listed.
- It moves. Between properties, or out entirely when a let is empty for the season.
- Guest usage is mostly streaming, so pick the allowance on that basis, not on an office benchmark.
- Lock the router down. It is in a house full of strangers, and that changes how you set it up.

Why fixed lines fit short lets badly
Nothing is wrong with fixed broadband in a holiday let. The mismatch is in the commercial shape of it.
- Install lead times. A new line can take weeks, and bookings do not wait. If you are furnishing a property to open for a season, broadband is often the thing that is not ready.
- Long contracts on a seasonal property. A cottage let eight months a year is paying twelve months of line rental.
- Somebody has to be there. An engineer appointment means a key, a person and a morning, for a property you may not live near.
- You may not be allowed to drill. Leasehold flats, listed buildings and converted barns all come with restrictions that a fixed install runs into.
- It does not move. If you sell the property or change what you do with it, the line stays where it is.
When 5G is the right answer
A 5G router is a box that plugs into a socket, takes a SIM and produces Wi-Fi. That is genuinely the whole thing. It is live when you plug it in.
| Situation | Why 5G suits it |
|---|---|
| Opening a new let | Online the day you furnish it, rather than whenever the install lands. No reason to delay a listing. |
| Seasonal or part-year letting | The connection can scale down or stop when the property is empty, instead of paying all year. |
| Listed or leasehold property | No external cable, no drilling, nothing to get permission for. |
| Rural or hard to reach | Often the only route that is not a long wait or a civils quote, especially where fibre has not arrived. |
| A gap between tenancies | Keeps a property lettable while a permanent line is ordered, or while one tenant leaves and another arrives. |
| Several properties | One account, one bill, pooled data across all of them. More on that below. |
Where a fixed line still wins
If the property is let continuously all year, has good fibre availability and the guests are long stay, a fixed line is usually cheaper per month and simpler. We will say so. 5G earns its place where speed of setup, flexibility or access restrictions matter more than the headline monthly cost.
How much data guests actually use
This is the number that decides whether the arrangement works, and office benchmarks are useless here. Guests do not send email. They stream.
A family watching television of an evening for a week will move a great deal more data than the same people would at work. Several people streaming in different rooms, on a wet afternoon, is the peak you are sizing for rather than the average.
- Assume streaming is the whole story. Video is almost all of it. Everything else rounds to nothing by comparison.
- Size for a full house, not a couple. Your worst week is the one you need to survive, and it is the one that produces the review.
- Think about back to back bookings. A changeover day does not reset an allowance, so a busy month is cumulative.
- Decide what happens at the limit. Slowing down mid stay is a complaint. Being charged for overage without knowing is worse. Pick deliberately.
Unlimited tariffs exist and are often the sensible choice for a let precisely because you are not in the property to manage it. It is worth knowing what unlimited means in practice first, which we cover in what unlimited really means on a business SIM.
Setting it up for a house full of strangers
This is the part most listings get wrong, because the router is treated like a home router. It is not. It is in a property occupied by people you have never met, who change every few days.
- Change the admin password. Not the Wi-Fi password, the one that gets into the router's settings. The default is printed on the box sitting in the hallway.
- Use a guest network for guests. If you have anything else on the property network, a smart lock, cameras in communal areas, your own storage, guests should not be on the same network as it.
- Put the Wi-Fi password somewhere obvious, in the welcome book and on a card. The most common Wi-Fi complaint is not speed, it is not being able to find the password.
- Do not use the property name as the password. It is on the listing.
- Place the router where guests will not unplug it. Behind a television, next to a socket somebody wants for a phone charger, is where it gets switched off.
- Be able to restart it remotely or have a neighbour or cleaner who can. A router that needs a power cycle on a Saturday night is otherwise a lost booking.
Our guide to guest Wi-Fi settings worth checking goes through the rest.
Getting the signal right in an older building
5G is only as good as the signal reaching the router, and the buildings that most need this solution are often the worst for it. Thick stone, old cottages, basement flats and converted barns all absorb signal.
Two things fix most of it. Put the router where the signal is, usually an upstairs window facing the right way, rather than in the cupboard with the meter. And check which network actually works at that postcode rather than assuming. Where coverage is genuinely marginal across networks, a multi-network SIM lets the router use whichever is strongest instead of being committed to one.
If the router has to live somewhere with signal but the Wi-Fi then will not reach the whole property, that is a separate and easily solved problem: an access point or two, cabled or mesh, puts the coverage where the guests are.
If you run more than one property
This is where it stops being a consumer purchase. Several lets on separate consumer broadband accounts means several bills, several providers, several passwords and nobody with a view of any of it.
On a business account with pooled data, every property draws from one allowance. A quiet cottage in February covers a busy apartment in August without anyone adjusting anything. One bill, one place to call, and you can see what each property is using before a guest complains rather than after.
