Office Cleaning Prices in the UK (2026 Cost Guide)

For any Berkshire or Surrey business, office cleaning is one of those costs that is surprisingly hard to pin down before you ask. Quotes arrive in different units — per hour, per square metre, per month — and rarely cover the same scope, which makes them almost impossible to compare like for like. This guide sets out realistic 2026 UK office cleaning prices, explains the three ways offices are usually priced, shows what a small, medium and large office typically pays, and walks through how to get a quote you can actually trust.

How office cleaning is priced: the three models

Office cleaning quotes come in three formats. Knowing which one you are looking at is the first step to comparing them fairly.

• Per cleaner-hour — you pay for time on site. Most common for small offices and irregular or one-off jobs, where an hourly rate is simple and fair.
• Per square metre or square foot — the price scales with floor area. Used to size larger contracts and one-off deep cleans, and the easiest way to sanity-check a quote for a big open-plan space.
• Fixed monthly contract — a set fee for an agreed schedule and scope. This is the norm for regular office cleaning and usually the best value, because the provider can plan staff and routes around your building.

Office cleaning prices by office size (UK, 2026)

The table below gives typical UK office cleaning prices in 2026 for a regular (contract) clean, grouped by office size, in line with published UK averages. Your exact figure depends heavily on how often you want the office cleaned and what is in scope.

Frequency is the single biggest driver: the same office cleaned twice a week versus every weekday can differ two- or three-fold in monthly cost. Treat the ranges above as a starting point for a survey-based quote, not a fixed price.

Hourly rates explained

Where cleaning is priced by the hour, most UK offices pay between £15 and £30 per cleaner per hour in 2026, with the core of quotes landing around £18–£25 and marketplace averages near £18. Rates rise for three predictable reasons: location (London and the South East, including much of Berkshire and Surrey, sit above the national average), timing (out-of-hours evening or early-morning cleaning typically adds around £5–£10 per hour), and specialism (deep cleans, carpet extraction and medical-grade hygiene run £30–£45 per hour and up). A very low headline rate usually means no insurance, no vetting and no cover when a cleaner is off — which costs more in the end.

Price per square metre and square foot

For larger offices and one-off jobs, pricing per area is often clearer than per hour. UK office cleaning generally works out at about £1–£3 per square metre (£0.10–£0.30 per square foot) for each clean, with larger floors costing less per unit because setup and travel are spread across more space. As a worked example, a 2,000 sq ft office cleaned five times a week at roughly £0.18 per sq ft comes to about £360 a week, or around £1,500 a month — which lines up with the medium-to-large monthly ranges above.

What changes the price

• Frequency: daily cleaning costs far more per month than two or three visits a week — but far less per visit.
• Size and layout: a warren of small offices, meeting rooms and multiple washrooms takes longer than the same floor area open-plan.
• Scope: washrooms, kitchens, internal glass, carpet extraction and waste handling each add time; consumables (bin liners, hand towels, soap) may be charged separately.
• Timing: out-of-hours cleaning avoids disrupting staff but carries a modest premium.
• Location: London and the South East, including Berkshire and Surrey, sit above the UK average; the Midlands and North sit below it.
• Specialist requirements: medical, laboratory or food-premises hygiene, and periodic deep cleans, are priced separately and higher.

What a monthly office cleaning contract should cover

A fixed monthly fee is only good value if you know exactly what it buys. A clear specification lists the tasks and their frequency by area, so nothing is left to assumption:

• Daily: washrooms sanitised and restocked, kitchens and breakout areas cleaned, bins emptied, reception and high-touch points wiped, floors vacuumed or mopped.
• Weekly or periodic: internal glass, detailed dusting, skirting and edges, and desk sanitising scaled to footfall.
• Quarterly to twice-yearly: carpet extraction, hard-floor treatment, high-level dust and washroom descaling — the deep-clean work routine cleaning cannot reach.
• Included as standard: products, equipment, method statements and risk assessments, plus a named account contact and a scheduled review.

One-off versus contract cleaning

A regular contract is almost always cheaper per visit than an ad-hoc booking, because the provider can plan a consistent route and team. A one-off or periodic deep office clean — carpet extraction, high-level dust, washroom descaling — is priced higher per hour because it is more intensive and has no ongoing commitment. Most offices run a routine contract for day-to-day hygiene and schedule a periodic deep clean on top; our guide to how often an office should be cleaned sets out a sensible frequency by area and footfall.

How to get an accurate office cleaning quote

The most useful thing you can do is make quotes comparable. Before you sign:

1. Ask for a site survey. A credible quote follows a walk-round of your premises, not a number guessed over the phone.
2. Specify frequency and scope area by area — reception and washrooms usually need daily attention, while desks and floors scale with headcount.
3. Confirm what is included: products and equipment, washroom consumables, VAT, and whether periodic deep cleans are extra.
4. Compare like for like — cost per visit and what is in scope, not just the headline hourly rate.
5. Check the essentials: public liability insurance, vetted and DBS-checked staff, and guaranteed cover when a cleaner is off sick or on holiday.

Office cleaning prices in Bracknell, Windsor and across Berkshire

Berkshire and the Surrey borders sit around or slightly above the national ranges above, reflecting South East labour costs. But the more useful local question is not the rate — it is what kind of premises you have, because that decides which pricing model you should be quoted on at all.

Bracknell: business parks and out-of-hours as the default

Bracknell is the most workplace-dense area we cover. It became a New Town after the Second World War and has since seen over £770 million of regeneration across the borough, including The Lexicon town-centre scheme. Office and business-park employment is substantial, and it shapes how cleaning is bought here.

Two things follow. First, out-of-hours cleaning is the norm rather than a premium option — business-park access arrangements and staff hours make a daytime visit both harder and more disruptive, so the £5–£10 per hour out-of-hours uplift is effectively the standing rate locally. Second, multi-tenant and managed buildings are common, so make sure your quote states clearly which areas are yours and which are the landlord's; paying twice for a shared reception is a genuinely common mistake.

Windsor and Maidenhead: smaller premises, higher presentation standard

Windsor offices are typically smaller and more client-facing — professional practices, agencies and consulting rooms, often in period or conservation-area buildings near the centre. Two consequences for price: these premises are usually quoted per cleaner-hour rather than per square metre because the areas are too small for area pricing to be meaningful, and reception and client-facing areas need daily attention regardless of headcount, which sets a floor on the contract that a pure desk count would understate.

Maidenhead is a mixture. The town-centre regeneration has produced modern, efficient office floorspace that prices well per square metre, alongside older premises that behave more like Windsor. If you are moving into new space, get the quote after fit-out is complete — after-builders cleaning is a separate job from your ongoing contract and should not be bundled into a monthly fee.

Ascot and Sunninghill: small offices and high-street premises

Around Ascot and Sunninghill the commercial stock is mostly high-street businesses, salons, professional offices and consulting rooms rather than corporate floorplates. These are small-office jobs — priced per cleaner-hour, usually two to five visits a week, cleaned early morning or after closing so trading is never interrupted. A typical small premises here falls at the lower end of the £195–£500 monthly range rather than needing a full contract structure.
