Window cleaning as a side hustle: the quick answer
Window cleaning is a realistic UK side hustle for fit, outdoor-minded people wanting to build a genuinely recurring local income round over time. Indicative startup costs are £150–£2,500, with an indicative initial income range of £400–£2,200 a month for 8–25 hours a week — an estimate rather than a guarantee, and one that depends on your location, pricing and demand.
Suits physically fit people comfortable working outdoors in most weather and, if using traditional methods or ladders, comfortable with heights. It is a poor fit for anyone uncomfortable with heights if planning to use ladders, or wanting fast income without round-building.
The main limitation is buying a full water-fed pole system before confirming there is enough local demand to justify the cost, and finding customers is rated low difficulty because most homes want their windows cleaned regularly and understand the service instantly, so the main task is becoming visible on a street rather than persuading anyone of the value.
The lowest-risk first step: start with a portable water-fed pole kit costing under £300 and a handful of streets close to home, taking on ten to fifteen customers before considering a van-mounted system.

What does this side hustle actually involve?
Most residential window cleaning today uses a water-fed pole system with purified water, allowing upper floors to be cleaned safely from the ground without ladders.
Customers are typically billed on a recurring four, six or eight-weekly cycle, which is what makes window cleaning one of the more genuinely recurring local services available.
A round is built street by street, since a tight, walkable or short-drive round of thirty to sixty regular customers is far more profitable than the same number spread across a wide area.
Typical customers
- Homeowners wanting a regular exterior clean
- Small shops and offices with street-facing windows
- Landlords maintaining rental properties
- Conservatory and skylight owners needing occasional specialist cleans
What you sell
- Regular exterior window clean on a recurring cycle
- Frame, sill and door glass cleaning

Likely a good fit if
- Fit, active people happy working outdoors in most weather
- Those comfortable building and sticking to a recurring round
- People with a vehicle able to carry a water tank and pole
- Anyone willing to start small and reinvest earnings into better kit
Probably not for you if
- Anyone with a fear of heights if using ladders or traditional methods

- Those unable to commit to a repeating schedule customers rely on

| Item | Typical cost |
|---|---|
| Van-mounted water-fed pole system with onboard tank and filtrationOnly worth it once a round of regular customers is established | £1,500–£4,000 |

Lowest-cost way to test demand: Start with a portable water-fed pole kit costing under £300 and a handful of streets close to home, taking on ten to fifteen customers before considering a van-mounted system.
How much can you realistically earn?
Twenty houses on a four-weekly cycle at £15 each brings around £300 per full round, and a round of eighty to a hundred properties spread across four weekly working days brings roughly £1,200–£1,800 a month.
Because cleans repeat on a fixed cycle, a mature round becomes quite predictable, unlike many one-off local services.
Weather causes short delays rather than lost income, since missed days are usually rescheduled within the same cycle rather than lost entirely.
| Pricing model | Typical example |
|---|---|
| Terraced or semi-detached house | £12–£20 per visit |
| Detached house | £18–£30 per visit |
| Small shop or office frontage | £15–£35 per visit |
| Conservatory roof clean | £25–£60, usually less frequent |
| Gutter clearing add-on | £40–£90 per property |
What changes your earnings most
- How tightly clustered your round is, since travel between houses is the main cost
- Whether you run a portable kit or invest in a van-mounted system as the round grows
- Add-on services such as gutter clearing and conservatory roofs
- How consistently customers stick to the cycle rather than cancelling ad hoc
How long does it take to earn anything?
With a basic kit and some direct doorstep or leaflet marketing, a first paid clean can happen within a week or two.
Before starting you need insurance and a clear, safe method, particularly if any traditional ladder work is involved.
Building an initial round of returning customers typically takes six to twelve weeks, since the value of the recurring cycle only becomes clear after the second or third visit.
It takes longer to reach full-time income than to get a first booking, since round-building is a steady accumulation process.
How do you get your first customers?
Doorstep and leaflet drops on target streets
Still the most effective way to start a tight local round; offer a discounted first clean to get on the books.
Local Facebook groups and Nextdoor
Good for filling gaps in a round and reaching customers who missed a leaflet.
Google Business Profile
Captures 'window cleaner near me' searches, especially valuable for small shop and office enquiries.
Referrals from existing customers
Ask happy customers if a neighbour would also like to be added to the round on the same day.
Objections you will hear, and how to answer them
- "How often do you come?" — be upfront about your standard cycle and offer flexibility for a small premium.
- "Will you damage my windows or frames?" — explain your method and show insurance if asked.
- "Can you just do it once?" — accept one-off jobs but price them higher than recurring customers to reflect the lack of ongoing value.
Why customers might not buy: Most homes want their windows cleaned regularly and understand the service instantly, so the main task is becoming visible on a street rather than persuading anyone of the value.
What are the advantages and the risks?
Advantages
- Genuinely recurring income once a round is established
- Low barrier to entry with a portable kit
- Physically active, outdoor work suits many people
- Predictable weekly schedule once the round matures
- Scope to add gutter clearing and other exterior services
Risks and challenges
- Weather can delay a day's work, though rarely cancels income entirely
- Working at height carries real safety risk if using ladders
- Physically demanding over a full working day
- Building a full round takes patience and consistent local marketing
What do you need to check legally, and for tax and insurance?
- Register as self-employed with HMRC once income exceeds the trading allowance.
- Public liability insurance is strongly advisable, particularly working near customers' property and vehicles.
- If using ladders rather than a water-fed pole system, follow HSE guidance on working at height, since falls from height are a leading cause of workplace injury.
- Tell your motor insurer you are using the vehicle for business, especially if carrying a water tank.
- Take care with waste water discharge if working near surface-water drains, particularly when using cleaning additives.
This is general guidance rather than legal, tax or insurance advice. Requirements may vary, so check current official guidance or speak to a suitable professional.
