15 Best Low-Cost Business Ideas in the UK (2026)

Last updated on July 1st, 2026 at 01:31 pm

You don’t just want a cheap business to start. You want one that pays you back quickly. 

Plenty of lists hand you fifteen ideas and stop there, with no real numbers attached. 

This one is different, since every idea below comes with a startup cost and a realistic earning range.

Some of these are hands-on trade work. Others are creative or desk-based. 

What they share is a low barrier to entry and a clear path to real income. None of them needs savings in the thousands before you start.

Here are 15 of the best low-cost business ideas in the UK for 2026.

Pick one that matches your skills, your tools, and the time you genuinely have free. Then jump straight into your first booking or client.

15 Best Low-Cost Business Ideas for 2026

1) Handyman Services

Startup cost: £200 to £500  |  Realistic earnings: £25 to £50/hour, £150 to £300/day

Homeowners need small jobs done fast, from flat-pack assembly to shelf fitting. 

A basic tool kit covers most starting jobs, and you add specialist tools as bigger work comes in. Most jobs take an hour or two, so a few bookings can fill a working day. 

List your services on MyBuilder or Checkatrade, and add a simple quote form on a basic website so inquiries reach you while you work.

2) Pressure Washing and Jet Washing

Startup cost: £300 to £800  |  Realistic earnings: £150 to £300/day

Driveways, patios, and decking build up grime quickly, and the results speak for themselves once people see them. 

A decent petrol pressure washer covers most residential jobs right from the start. 

Photograph your own driveway first, then offer a neighbor a discounted clean for your first before-and-after post. 

Spring and early summer bring the steadiest bookings, so build your client list before the season starts.

3) Window Cleaning

Startup cost: £200 to £1,000  |  Realistic earnings: £20 to £40/hour, £600 to £1,000/week

Windows need cleaning every few weeks, which turns one client into months of repeat income. 

A traditional squeegee setup costs far less than a water-fed pole system, so start there if funds are tight. 

Build a tight round in one area first, to cut travel time between jobs. 

Knock on doors in residential streets and offer a discounted first clean to fill your early diary.

4) Gutter Cleaning and Maintenance

Startup cost: £200 to £800  |  Realistic earnings: £50 to £100/house, £300 to £500/day

Blocked gutters cause real damage, which gives homeowners a genuine reason to book quickly. 

A ladder and basic tools cover your first jobs, though a gutter vacuum system speeds up the work and improves safety.

Autumn brings a clear spike in demand as leaves pile up. Knock on doors after a storm, since visible overflow makes the sale for you.

5) Oven Cleaning

Startup cost: £500 to £1,500  |  Realistic earnings: £40 to £80/oven, £200 to £400/day

Almost everyone hates cleaning their own oven, which keeps demand steady all year. 

A short training course or a few tutorials cover the technique, alongside the right chemicals and tools. 

Letting agents need ovens cleaned between every tenancy, and one contact there can hand you several jobs a month. 

Photograph the before and after of your first job, since the contrast does most of the selling.

6) Mobile Car Valeting

Startup cost: £300 to £600  |  Realistic earnings: £20 to £40/car, £150 to £300/day

People would rather pay for a clean car than spend their Saturday washing one themselves. 

A portable pressure washer and a water tank cover most jobs without needing a fixed site. 

Detail your own car first for marketing photos, then target residential streets and office car parks. 

Offer a monthly package to your first few clients to build recurring income early.

7) Furniture Assembly Service

Startup cost: £100 to £200  |  Realistic earnings: £30 to £60/hour

Online furniture sales keep growing, and most buyers would rather pay someone else to build the flat-pack. 

A basic tool kit and reliable transport cover almost every job on this list. 

List yourself on TaskRabbit or MyBuilder, and reach out to local removal companies who often need an assembly partner. 

Time your first few jobs closely, so your pricing reflects how long each piece genuinely takes.

8) Gardening and Grounds Maintenance

Startup cost: £300 to £800  |  Realistic earnings: £20 to £35/hour, £150 to £250/day

Lawns and hedges need regular attention through the growing season, which creates repeat bookings rather than one-off jobs. 

Reliable second-hand equipment keeps your starting costs down while you build a client base. 

Older homeowners often need the most help and tend to book consistently. 

Leaflet a few affluent streets near you, and price by the job rather than by the hour once you know your pace.

9) House Removals

Startup cost: £500 to £2,000  |  Realistic earnings: £200 to £400/job, more for long-distance moves

Thousands of people move home in the UK every month, and most need help loading a van.

A reliable van and the right insurance cover the basics, since damaged goods and accidents are a real risk in this work.

Local moves are the easiest way to start, before you take on longer journeys.

A simple booking page on a basic website helps people lock in a date without back-and-forth messages.

10) Sewing and Alterations

Startup cost: £100 to £300  |  Realistic earnings: £15 to £40/item

Sewing machines have all but disappeared from most UK homes, which leaves a genuine gap for anyone who can still use one. 

A good machine and basic supplies cover almost every job, from hemming jeans to making curtains. 

Local dry cleaners and clothing shops often welcome a reliable alterations partner. 

Start by offering your services through one shop, then expand once word of mouth picks up.

11) Mobile Hairdressing

Startup cost: £200 to £600  |  Realistic earnings: £25 to £50/client

Many clients would rather have their hair done at home than travel to a salon, especially with young children or limited time. 

Your own kit and a reliable car cover most of your starting costs. 

Bring your existing salon clients with you if your contract allows it, and offer friends and family a trial cut while you build momentum. 

Word of mouth travels fast once people see the convenience.

12) Event and Product Photography

Startup cost: £500 to £2,000  |  Realistic earnings: £200 to £500/event, £50 to £150/hour

Every business needs photos, and weddings alone routinely pay several hundred pounds per booking. 

A solid camera and basic editing software cover most early work, with lighting gear added as you grow. 

Online sellers need product photography just as often as couples need wedding coverage. 

Build a simple portfolio site early, since most new clients check your previous work before they book.

13) Video Editing for Businesses

Startup cost: £20/month  |  Realistic earnings: £50 to £200/video

Video content is growing across social media and YouTube, but most small businesses have no in-house editor. 

A single software subscription covers your entire starting toolkit. 

Fast turnaround on a first project often leads straight to repeat work, since businesses need a steady supply of clips. 

Offer one local business a discounted first edit, then use the result as your sample reel.

14) Online Courses

Startup cost: £0 to £200  |  Realistic earnings: scales with enrolments, often £500 plus per month once established

If you already know a subject well, packaging that knowledge into a course can pay off long after you finish recording it. 

Platforms like Teachable and Udemy handle hosting, payment, and delivery, so you only need to focus on the content. 

Pick one specific skill to teach, rather than a broad subject nobody searches for. 

Your first course rarely makes much money, but it builds the proof you need to launch a second one with more confidence.

15) Interior Design

Startup cost: £200 to £1,000  |  Realistic earnings: £200 to £800/project, more for full renovations

Not everyone has an eye for how a room should come together, and they will pay for that judgment. 

A strong portfolio counts more here than any formal qualification. 

Virtual interior design, run entirely through online platforms, lets you take on clients outside your local area. 

Build your first three projects around friends or family, then publish the before-and-after photos on a simple website to attract paying clients.

Your Next Step

Fifteen ideas, and every single one comes with a number attached, just like we promised at the start. 

The cheapest businesses to start are not always the ones that pay the most, so weigh the earning range against your own time and tools.

Most of the ideas on this list work best once people can find you online before they ever call. 

A handyman with a quote form gets booked faster than one with only a phone number. 

A photographer with a portfolio site closes more inquiries than one who relies solely on word of mouth.

That’s where a simple website and a UK domain through Truehost come in. 

Our AI Website Builder turns any of these fifteen ideas into a working site within minutes, so customers can find you before your first day is even over. 

Pick the idea that pays, then make sure people can find you when they search.
