A building with sparkling, streak-free windows says a lot about the business inside. It says you’re professional, you care about details, and you create a bright, welcoming environment for your staff and customers. But achieving that perfect shine comes at a cost, and figuring out that cost can be a minefield!
You might hear one company quote per hour, another per window, and a third gives you a single, all-in price for the job. It can be confusing.
Let’s break down exactly how commercial window cleaning is priced in the UK. We’ll explain the different pricing models, explore the factors that can make your quote higher or lower, and show you the simplest way to get a firm, fair price from a trusted professional.
Average Commercial Window Cleaning Prices
Let’s get straight to it. You want ballpark figures. While every job is unique, here are some typical price ranges you can expect to see from UK window cleaning companies.
| Service Type | Average Price Range | Notes |
| Price Per Window | £3 – £10+ | Varies hugely on size and access. |
| Price Per Hour | £25 – £45+ per cleaner | Often for tricky or internal jobs. |
| Small Shop Front | £20 – £50 | For a standard, ground-floor retail unit. |
| Medium Office (2-3 storeys) | £80 – £250 | Typically using a ‘Reach and Wash’ system. |
| Large Office Block | £300 – £1000+ | May require specialist access equipment. |
Important: Think of these numbers as a rough guide. The final price on your quote will depend on the specific details of your building, which we’ll dive into now.
The Three Main Ways Window Cleaning is Priced
When you ask for window cleaning rates, you’ll usually get a price based on one of these three models.
1. Per Window Pricing
This sounds simple, but the definition of “a window” can vary. A company might charge £3 for a small, easy-to-reach window, but £10 or more for a large, difficult-to-access one on the second floor. This method is less common for large commercial buildings because it becomes complicated to count and price every single pane of glass.
2. Per Hour Pricing
An hourly rate, typically £25 to £45+ per cleaner, is often used for:
- Initial “deep cleans” where the time needed is uncertain.
- Post-construction cleaning to remove paint, plaster, or silicone.
- Complex internal glass cleaning (e.g. partitions, balustrades).
The downside for you is uncertainty. A job that takes longer than expected will cost more, so it can be hard to budget for.
3. Per Job (A Fixed Quote) – The Gold Standard
This is the most common and reliable method for commercial window cleaning. A professional will assess your building (either in person or using tools like Google Street View) and provide a single, fixed price to complete the entire job.
This is the best option for businesses. You know the exact cost upfront, with no hidden surprises. The price includes all labour, equipment, and insurance. It means the window cleaning company takes on the risk of the job taking longer than planned, not you.
This is why getting a tailored quote is so important. It moves you from guesswork to a guaranteed price.

Key Factors That Influence Your Window Cleaning Quote
So, what details do professionals look at when they build your quote? It all comes down to a simple formula: Time + Risk + Equipment = Price.
Here are the biggest factors that determine the final cost.
1. Accessibility: Ladders, Poles, or Ropes?
How a cleaner reaches your windows is the single biggest factor in your quote.
- Ground Floor (Traditional Methods): Windows that can be cleaned from the ground or with a small stepladder are the cheapest. This is typical for shop fronts and single-storey offices.
- Reach and Wash Systems: This is the most common method for buildings up to 5-6 storeys. Cleaners use long, water-fed poles to clean windows from the safety of the ground. Purified water is used, which dries to a perfect, streak-free finish without needing to be squeegeed. It’s highly efficient and safe, often making it more cost-effective than other methods.
- High-Rise Access (Specialist Equipment): For taller buildings, things get more complex and expensive.
- Mobile Platforms (Cherry Pickers): A hydraulic platform lifts cleaners to the required height. This requires a certified operator and space to manoeuvre the vehicle.
- Rope Access (Abseiling): For skyscrapers or buildings with difficult access, highly trained and insured technicians abseil down the building. This is a specialist skill that carries a premium price.
- Building Cradles: Some modern buildings have a permanent cradle system installed on the roof, which lowers cleaners down the façade.
2. The Size and Number of Windows
This one is straightforward: more glass takes more time to clean. A large office block covered in floor-to-ceiling glass will cost significantly more than a building of the same height with just a few small windows per floor.
3. The “How Dirty is Dirty?” Factor
Is this the first time the windows have been professionally cleaned in five years, or are they cleaned every month?
- First-Time or Annual Cleans: These cost more because there’s a heavy build-up of traffic film, algae, and grime that requires more effort and time to remove.
- Regular Maintenance Cleans: If you’re on a monthly or bi-monthly schedule, each clean is faster and easier. The price per visit is therefore much lower.
4. How Often You Need Them Cleaned (Frequency)
Most commercial window cleaning companies offer discounts for regular contracts. A one-off clean carries the highest price. Committing to a regular schedule (e.g. monthly, quarterly) will significantly reduce the cost per visit. It’s a win-win: you get consistently clean windows for a better price, and the company gets reliable, ongoing work.
5. Your Building’s Location
Operating costs vary across the UK. A window cleaning quote in central London or another major city will likely be higher than for an identical building in a smaller town, simply due to higher wages, congestion charges, and parking costs for the cleaning crew.
6. More Than Just the Glass
A standard window cleaning quote usually covers cleaning the glass itself. If you also need the frames, sills, panelling, or signage cleaned, make sure to specify this. These extra services will add to the overall cost but can make a huge difference to your building’s appearance.
Putting It All Together: Example Scenarios
Let’s look at how these factors combine in the real world.
- Scenario 1: The High Street Boutique
- Building: A single ground-floor retail shop.
- Access: Easy, from the pavement.
- Frequency: Monthly.
- Estimated Cost: £25 – £40 per clean. The job is quick, low-risk, and regular, making it very affordable.
- Scenario 2: The Three-Storey Regional Office
- Building: A modern office block with 40 windows.
- Access: Perfect for a Reach and Wash system.
- Frequency: Quarterly.
- Estimated Cost: £120 – £200 per clean. The efficiency of the pole system keeps costs reasonable, and the quarterly contract helps secure a good rate.
- Scenario 3: The City Centre Corporate HQ
- Building: A 10-storey building with complex glass architecture.
- Access: Requires a combination of a mobile platform for lower levels and rope access for the highest points.
- Frequency: A one-off “deep clean” is required before starting a bi-annual contract.
- Estimated First Clean Cost: £1,500 – £3,000+. The high cost reflects the specialist equipment, certified operators, high-risk insurance, and the intensive labour of a first-time deep clean. The subsequent bi-annual cleans would be cheaper.
