Commercial Cladding Cleaning Costs in London: What Drives Your Quote?

Most cladding cleaning price guides quote a rate per square metre. That works well for a warehouse on an open industrial estate. It works far less well for an eight-storey office on a Southwark street or a residential tower in Canary Wharf, where how the team reaches the cladding often costs more than the cleaning itself.

This guide is written for property managers, facility managers and building owners budgeting for commercial cladding cleaning on London buildings.

It explains how quotes are really built, what each access method costs, and how to keep the annual spend under control.

If you’re budgeting for a whole facade, including stone, brick or glazing, our guide to facade cleaning costs in the UK covers the wider picture.

On low-rise buildings with good ground access, contractors usually price by area or by elevation. Once a building goes beyond four or five storeys, pricing shifts to day rates or a price per drop. A drop is one vertical run of the facade from roof to ground.

The reason is simple. On a tall building, the cleaning itself is a relatively small part of the job. Most of the cost is in:

• Access equipment: platform hire, rope access rigging or cradle operation
• Set up and site management: exclusion zones, pedestrian control and permits
• Team size and certification: IRATA rope access technicians or IPAF trained platform operators
• Time on site: cladding takes longer to clean than glass, so drops are slower

A per square metre figure from a national guide will usually underestimate a London high-rise job and overestimate a simple low-rise one. Ask any contractor which pricing basis their quote uses, so you can compare like for like.

The table below gives indicative 2026 prices for a routine clean with light to moderate soiling, excluding VAT. Your building’s exact figure depends on its layout, material and condition, which is why a site survey matters.

A few points help explain the ranges.

Water-fed pole is the most cost-effective method where it can reach. There is no platform hire and set up is quick, so the price is mostly labour.

Cherry pickers carry a fixed daily platform cost whether the team cleans one elevation or four. Grouping all elevations into the same visit makes the most of the hire.

Abseiling has no platform cost but needs a qualified rope access team and suitable roof anchors. On buildings with few drops it is often cheaper than a cherry picker, even at mid-rise heights.

Cradles are efficient on very tall, uniform facades. However, the building’s own BMU must be in working order and have a current thorough examination.

Under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), equipment used to lift people must be thoroughly examined at least every six months. A lapsed examination can delay the clean or force a switch to abseiling.

Material changes how long each panel takes and which products can safely be used. It matters less to the total price than access, but it can still move a quote noticeably.

Many cladding manufacturers publish maintenance guidance, and some make routine cleaning a condition of their coating warranty.

Before your contractor starts, check whether your panels have a recommended cleaning frequency or approved products. Using the wrong chemicals or pressure can invalidate a warranty that is worth far more than the clean.

How dirty the cladding is will move the price within the bands above.

• Light (dust, traffic film): a single pass, at the lower end of the range
• Moderate (algae, pollution streaking, bird fouling): pre-treatment and longer dwell times, typically adding 20% to 50%
• Heavy (carbon deposits, graffiti, years of neglect): multiple treatments and slower drops, sometimes doubling the cost of a routine clean

There is a point where cleaning stops being the answer. If panels are chalking, oxidised or have a failing coating, cleaning will improve them but won’t restore them.

That is a refurbishment job, usually involving specialist recoating, and is priced very differently.

The most reliable way to avoid that cost is a regular cleaning cycle, so dirt never has time to damage the finish. We explain how this works in more detail in how commercial cladding cleaning prevents facade repairs.

Yes, and on taller London buildings this is the single most effective way to reduce cladding cleaning costs.

When a rope access team, cherry picker or cradle is already on your building for the scheduled window clean, the expensive part of the job is already paid for.

Adding the cladding to the same drops means you pay for rigging, platform hire, permits and exclusion zones once rather than twice.

All Clean Services regularly combines commercial window cleaning with cladding cleaning for this reason. A practical approach for many buildings is a twice-yearly cladding clean timed to coincide with two of the regular window cleaning visits.

Most commercial cladding is cleaned once or twice a year. Buildings beside busy roads, in polluted central areas or with light-coloured panels often need the higher frequency.

When you budget, work from the annual figure rather than a single visit, especially across a portfolio. For example, a mid-rise office cleaned twice a year at £2,500 per visit needs £5,000 in the annual maintenance budget.

A contracted schedule also tends to reduce the cost per visit. The contractor can plan access and staffing ahead, and regular cleaning keeps soiling light, so each visit is quicker.

For residential and mixed-use blocks in England, cladding cleaning is usually recovered through the service charge.

Under Section 20 of the Landlord and Tenant Act 1985, landlords must consult leaseholders before entering a qualifying long-term agreement (a contract of more than 12 months) where any leaseholder will contribute more than £100 a year.

Consultation is also required for qualifying works costing any leaseholder more than £250.

A multi-year cleaning contract can therefore trigger consultation, and the process adds time. Build it into your planning, and take advice from your managing agent or a property lawyer if you are unsure whether it applies.

Cladding cleaning is not a fire safety inspection and should never be presented as one. However, many buildings now have external wall surveys or regular facade inspections.

Scheduling the clean alongside these can save access costs, and clean panels are easier to inspect visually. It is worth asking whether your surveyor and cleaning contractor can share the same access window.

These items rarely appear in national price guides but often affect London quotes.

Highway licences: Placing a cherry picker on a pavement or road usually needs a licence from the local highway authority, which is the borough council, or Transport for London on red routes. Lead times and fees vary by borough, so allow time for this in your schedule.

Parking suspensions: Bays may need suspending for platform vehicles or reach and wash vans, which carries a separate council charge.

Managed estates: Areas such as Canary Wharf, the City and large business parks often have their own permit, RAMS approval and working-hours rules. These can add administration time and limit when work can take place.

Out-of-hours working: Busy frontages and shopping streets may require early morning or weekend work to protect pedestrians, which can increase labour costs.

Water and runoff: Cleaning products and wastewater must be controlled so they don’t enter surface water drains. Confirm that your contractor’s method statement covers this.

These illustrative scenarios show how the factors above combine. They are not quotes for specific buildings.

Three-storey business park office, about 900m² of powder-coated aluminium panels with light to moderate soiling, cleaned by a water-fed pole from the car park. Estimated cost: £1,200 to £2,000 per visit.

Eight-storey office on a Southwark street, ACM panels cleaned from a cherry picker positioned on the pavement, needing a highway licence and three days on site. Estimated cost: £3,000 to £4,800 including the platform, plus the borough licence fee.

22-storey residential tower in Tower Hamlets, mixed cladding and glazing, cleaned by abseiling across 24 drops. A standalone cladding clean is estimated at £8,000 to £11,000.

If the cladding is added to an already scheduled window clean on the same drops, the additional cost for the cladding is typically far lower, estimated here at £4,500 to £7,000, because rigging and set up are already covered.

The more detail you provide, the more accurate your first quote will be. When you contact a contractor, include:

• The building’s height or number of storeys.
• The cladding material, if known, and any manufacturer guidance.
• Recent photos of each elevation showing current condition.
• Access constraints such as street frontage, roof anchors or an installed cradle.
• Your preferred frequency and whether you’d like it combined with window cleaning.

Check that every quote includes RAMS, confirms insurance and states the access method and pricing basis, so you are comparing the same service.

Our guide to what facility managers must check before hiring a window cleaner covers the compliance documents in more detail. It is also worth reading about the hidden risks of cheap window cleaning before choosing on price alone.
