The essential tech kit for starting a business from home

When your business runs from home, your broadband is your shop front, your laptop is your office and a power cut is an unplanned day off. The kit that keeps a home business running is neither exotic nor especially expensive. It just needs choosing with reliability in mind, rather than headline specifications.

Buy for reliability, not specifications

The failures that really hurt a small business are rarely dramatic. They are a connection that drops in the middle of a pitch, a laptop that dies with the only copy of your accounts on it, a password reused once too often. None of them needs cutting-edge technology to prevent. They need a few sensible purchases and some boring habits.

So as you read on, think less about what is fastest and more about what happens when something goes wrong. Every item here is either something you use every day or something that saves you on the day you need it.

Broadband: your most important supplier

Start by checking whether full fibre is available at your address, because it is faster and more consistent than the older part-fibre connections that rely on copper for the last stretch. Your provider's website, or an independent availability checker, will tell you what you can get.

Look at the upload speed, not just the download speed. Upload decides how smoothly you appear on video calls, how quickly large files reach clients and how long your online backups take. Many cheaper packages offer generous download speeds with very little upload.

Consider a business broadband package once the business depends on it. The main benefits are faster repairs when something goes wrong and, if you need one, a fixed IP address for remote access or certain business systems.

Get the connection to your desk

Wi-Fi is convenient, but for a desk that never moves, an Ethernet cable is faster, more stable and far less likely to drop a call. If the router is at the other end of the house, a mesh Wi-Fi system with a unit near your desk, or a pair of powerline adapters that send the connection through your mains wiring, will usually beat a single router struggling through brick walls.

A backup connection for when the line goes down

Every connection fails eventually, usually at the worst moment. For the occasional outage, tethering your laptop to your phone gets you through an afternoon. If the business cannot afford to stop, a dedicated 4G or 5G router with its own data SIM is better, ideally on a different mobile network from your phone, so one network's bad day does not take out both. Some routers can switch to a mobile connection automatically when the broadband drops, so you may not even notice.

Protect the power

A power cut or a surge can corrupt files halfway through being written and damage equipment. A small uninterruptible power supply, or UPS, keeps your router and computer running for long enough to save work and shut down cleanly, and it means a flicker in the mains no longer knocks you offline. Plug everything else on the desk into surge-protected extension leads.

A laptop has its own battery, which is one reason many home businesses run on one. But the router still needs power, so even a laptop user benefits from a UPS for the broadband kit.

A separate business phone number

Giving customers your personal mobile number feels convenient until they ring on a Sunday evening. A separate business number keeps the two worlds apart and lets you switch work off when you need to.

You do not need a second phone. Most modern smartphones support two numbers at once using a second SIM or an eSIM, and calls show which number they came in on. Alternatively, an internet phone service gives you a business number that works through an app on your phone and laptop, with voicemail, call forwarding and business hours built in.

Back up everything, twice

If your laptop were stolen tonight, what would you lose? For many new businesses, the honest answer is far too much.

The standard approach is the 3-2-1 rule: three copies of anything important, on two different types of storage, with one copy kept somewhere else. For a home business, that can be as simple as:

• your files on your laptop;
• an automatic backup to a cloud service;
• a regular copy to an external SSD that you unplug and keep away from the desk.

Rugged portable SSDs, such as Samsung's T-series or SanDisk's Extreme range, are small, quick and survive being knocked about. As the business grows, a network storage box, often called a NAS, from makers such as Synology, can back up every computer in the house automatically.

Then test it. Pick a file or a folder every few months and restore it from each backup. A backup you have never restored is a hope, not a plan.

Lock the doors: passwords and security keys

Your email account is the master key to the business, because almost everything else can be reset through it. Protect it, and your bank, domain and payment accounts, before anything else.

Use a password manager such as 1Password or Bitwarden, so every account has a long, unique password you never have to remember. Turn on two-step verification everywhere it is offered. And for the accounts that matter most, add a hardware security key such as a YubiKey: a small device on your key ring that you tap or plug in to prove it is really you. It stops the most common account takeover tricks in their tracks, because it will not respond to a fake login page. Buy two, and keep the spare somewhere safe.

A laptop and a second screen

Most home businesses run on a laptop, and we cover what matters, memory above all, in our guide on what to look for in a laptop. At your desk, add a second screen: it is the single biggest productivity upgrade you can buy, and our monitor buying guide explains the options.

Printing and paperwork

Most home businesses print far less than they expect. A scanning app on your phone turns receipts, contracts and letters into tidy files in seconds, which covers most needs. If you do print occasionally, a compact mono laser printer is usually a better choice than an inkjet, because laser toner does not dry out between uses. And keep a cross-cut shredder for anything with customer or financial details on it.

The small things that save the day

• Spare cables for everything you rely on, kept together in one drawer.
• A wired mouse and keyboard for the day the wireless ones run flat.
• Chargers that stay at the desk, so the one your business depends on never wanders off to another room.
• A printed sheet of emergency details: your broadband provider's fault line, your hosting and domain support contacts, and where the backup drive lives. When the internet is down, you cannot look them up online.

What to buy first

If you are starting from scratch, this order covers the biggest risks first:

1. A password manager and two-step verification on every account.
2. A backup routine: cloud backup plus an external SSD.
3. The best broadband available at your address, wired to your desk.
4. A backup connection, even if it is just your phone.
5. A UPS for the router and computer.
6. A second screen and a headset for calls.
7. A hardware security key, or two, for your most important accounts.

The short version

A home business does not need a server room, but it does need the basics done properly: a dependable connection with a fallback, protected power, real backups and locked-down accounts. Get those right and the dull disasters that sink small businesses simply do not happen to you. Once the tech is sorted, turn to how to set up the room itself.
