Millions of Britons now earn money outside their main job, and the gap between what people assume it costs to get trading online and what it actually costs has become its own small economy. A working domain, hosting and a functional site can be running for well under £100 in year one; the real cost of starting a side business UK shows up later, in renewal prices, add-ons nobody needed and subscriptions abandoned within six months. This piece sets out what HMRC lets you earn before it wants to know, what a website should cost at each stage, and which providers actually survive contact with a tight budget.
What Getting A Small Business Online Actually Costs
Getting a small business online is cheaper than most people assume, and pricier than the adverts suggest once the discount period ends. A .co.uk domain runs around £10 to £15 a year, and a starter hosting plan or a business website builder with hosting bundled in typically lands between £5 and £15 a month once any introductory rate expires. For someone testing whether a candle business or a tutoring sideline has legs, that is the entire side hustle setup costs conversation: a domain, a template-built site, an SSL certificate most hosts now bundle free, and a way to take payment. Where people overspend is upstream of all that. Custom logo packages, paid ad spend before there is a product worth advertising, and premium themes bought on day one are the fastest ways to burn through the first three months of runway before anyone knows if the idea works.
How Many People Are Quietly Running A Second Income?
Side hustle used to mean cash-in-hand babysitting or an eBay clear-out. It’s now a measurable slice of the economy, sitting alongside a self-employed workforce that has hovered around four million people for most of the past decade, according to the Office for National Statistics. Cost-of-living pressure has pulled more salaried workers into that space: tutoring, resale, freelance design, small-batch food. earlier reporting on side hustles found that most cluster in creative industries, retail and e-commerce, or technology services, rather than the gig-economy driving jobs people tend to assume dominate the space. That pattern shapes the cost question: a tutor needs a booking page and a payment link, a reseller needs a shopfront and decent photography, and neither needs the infrastructure a growing retailer will eventually want.
What Can You Earn Before HMRC Wants To Know?
HMRC’s trading allowance lets anyone earn up to £1,000 in gross trading income a year without registering as self-employed or filing a return, a threshold set out in the department’s own trading income guidance. Cross it and the paperwork starts, even if the site is still losing money on hosting fees. That figure shapes early decisions more than any marketing choice: some people deliberately keep a hobby project under the £1,000 mark to avoid the admin of self-assessment, others treat it as the starting gun for something bigger. Either way, it’s worth knowing before spending anything, because the infrastructure costs below are the same whether the venture earns £200 or £20,000 in its first year.
Six UK Providers, Judged On What They Cost Once The Offer Ends
Judged from the perspective of someone testing an idea for six months rather than building a forever-business, the providers that matter are the ones with honest renewal pricing and an easy way out. Exit matters as much as entry: a provider that makes it painless to export a domain, cancel a plan or move a site elsewhere is worth more to a six-month experiment than one offering a marginally prettier template. Here is how six UK-market options compare on the numbers that actually bite once the introductory offer ends.
| Provider | First-year price* | Renewal price* | What’s included | Support | Server location |
| one.com | ~£2 to £3/month | ~£9 to £12/month | Domain, website builder, email, SSL | 24/7 chat | EU (Denmark) |
| IONOS | ~£1/month | ~£8 to £10/month | Domain, builder, email | 24/7 phone | UK/Germany |
| GoDaddy | ~£1 to £5/month | ~£15 to £20/month | Domain, builder, basic marketing tools | 24/7 phone/chat | UK/US |
| 123 Reg | ~£3 to £5/month | ~£10 to £14/month | Domain, hosting, email | UK office hours, phone and chat | UK |
| Krystal | ~£4 to £6/month | Same as first year | Hosting, SSL, email, no forced upsells | UK office hours | UK (Wales) |
| Hostinger | ~£2/month | ~£6 to £9/month | Domain (year one), builder, email | 24/7 chat | EU and global options |

So Which Builder Survives A Six-Month Experiment?
There isn’t one winner, because the six providers above are solving slightly different problems. Someone testing a craft business with no coding time wants the simplest builder and a renewal price they won’t resent paying twice, which points towards one.com or Hostinger rather than a bare hosting account. Someone who already knows the site will outlive the test phase, and wants UK-based support without a jump in year two, gets more from Krystal’s flatter pricing even if the interface is less polished. Anyone leaning on domain, email and hosting from the same UK company they can phone during office hours is better served by 123 Reg. GoDaddy’s aggressive entry pricing suits people who are certain they will cancel or renegotiate before the second-year invoice lands, and not much beyond that. For anyone still deciding whether the idea is worth pursuing at all, a look at low-cost side job ideas is worth doing before committing to twelve months of hosting.
The honest number for most people is somewhere between £70 and £150 to get properly trading in year one, HMRC allowance included, provided nobody buys a logo package before they’ve made a sale. The bigger cost, most operators find out the hard way, is the renewal invoice twelve months later, arriving quietly for a business that either never launched or has already outgrown the plan it started on.
