Why Commercial Cleaning Contracts Are Worth the Effort
You’ve got the team, the equipment, and the van. But the phone isn’t ringing enough, and your crew’s sitting idle on Tuesdays. If you’re running a cleaning company in the UK and wondering how to get commercial cleaning contracts, you’re not alone – and you’re looking in the right place.
The UK commercial cleaning market is worth £9.8 billion in 2026, growing at 5.6% per year over the last five years. There are over 77,500 cleaning businesses across the country, 83% of them micro-businesses with fewer than 10 staff. That’s a crowded market – but also a growing one.
Commercial contracts are the engine of a cleaning business. Compared to one-off residential jobs, they offer:
- Predictable income. A monthly contract with an office block or restaurant is worth more than a dozen one-off deep cleans.
- Lower acquisition cost. Win one contract and you’re paid for months or years, not chasing the next job every week.
- Higher lifetime value. The average commercial cleaning contract runs 12–24 months. One win pays for itself many times over.
The challenge isn’t that contracts don’t exist. It’s that most cleaning companies are fishing in the same pond – waiting for inbound calls, checking the same job boards, and hoping for referrals. The strategies below cover every channel that works, including one that almost nobody is using yet.
Public Sector vs Private Sector: Two Different Games
Before diving into tactics, understand that commercial cleaning contracts split into two very different markets.
Public sector – councils, NHS trusts, schools, government offices – uses formal procurement. Everything goes through a tender process. You find the opportunity on a portal, submit a bid, and compete on price, quality, and compliance. It’s structured, transparent, and slow. But the contracts are large and long-term.
Private sector – restaurants, offices, retail, warehouses – is relationship-driven. There’s no portal. You find the decision-maker, make your pitch, and win on trust, price, and availability. It’s faster but less predictable.
Most guides only cover one side. You need both.
| Dimension | Public sector | Private sector |
|---|---|---|
| How you find work | Tender portals | Outreach, networking, referrals |
| Decision-maker | Procurement team | Owner, office manager, FM company |
| Sales cycle | 4–12 weeks | 1–4 weeks |
| Contract length | 1–5 years | 6–24 months |
| Competition | 5–20 bidders per tender | 2–3 quotes |
| Key differentiator | Compliance, accreditations, price | Reliability, speed, trust |
Win Public Sector Work Through Tender Platforms
If you’re not checking tender platforms, you’re leaving money on the table. Every public body in the UK must advertise contracts above a certain threshold, and cleaning is one of the most commonly tendered services.
Where to find tenders:
- Contracts Finder (contractsfinder.service.gov.uk) – free, covers all UK government contracts. Search “cleaning” and filter by location. Over 1,400 cleaning contracts were listed in the past year alone.
- Find a Tender (find-tender.service.gov.uk) – for higher-value contracts that used to go through the EU’s OJEU system.
- Supply2Gov – aggregates public sector opportunities with email alerts.
- Your local council’s procurement page – many smaller contracts are advertised directly on council websites and never reach the national portals.
How to win:
- Get accredited. Most public sector contracts require ISO 9001 (quality management) or BICSc (British Institute of Cleaning Science) certification. If you don’t have these, start the process now – it takes 3–6 months but unlocks an entire tier of work.
- Start small. Sub-contract through a larger provider to build your track record. Many Tier 1 contractors need local cleaning firms for specific sites.
- Price carefully. Public sector buyers evaluate on a weighted score – typically 60% quality, 40% price. Don’t just undercut everyone. Show how your quality justifies the price.
Build a Website That Wins Local Search
When a facility manager Googles “commercial cleaning [your area],” your business needs to appear. Most cleaning companies either have no website or have one that was built in 2015 and never updated. This is one of the fastest ways to generate commercial cleaning leads without spending on ads.
The basics that matter:
- Google Business Profile. Claim it, fill in every field, add photos of your team at work, and ask every happy client for a review. This is what shows up in the map pack – and for local services, the map pack gets more clicks than the organic results below it.
- Service pages by type. Don’t just have one “services” page. Create separate pages for office cleaning, restaurant cleaning, industrial cleaning, end-of-tenancy, and deep cleaning. Each one targets different search terms.
- Location pages. If you serve multiple areas, create a page for each: “Commercial Cleaning in Croydon,” “Office Cleaning in Bromley.” These rank for “[service] in [area]” searches with almost no competition.
- Case studies. One real case study with photos, the client’s problem, and the outcome you delivered is worth more than ten generic testimonials.
You don’t need a fancy website. A clean, fast site with clear service pages, a phone number on every page, and a Google Business Profile with 20+ reviews will outperform 90% of competitors.
Network With Facility Managers and Property Companies
The highest-value private sector contracts don’t get advertised. They go to the cleaning company the facility manager already knows and trusts. Getting into those networks takes time, but the contracts are bigger and more stable.
Where to find decision-makers:
- Property management companies. They manage office buildings, retail parks, and residential blocks – and they outsource cleaning. A relationship with one property manager can lead to contracts across their entire portfolio.
- Trade associations. The British Institute of Cleaning Science (BICSc) and the Cleaning & Support Services Association (CSSA) run events where you’ll meet buyers and competitors. Show up.
- Local business networking. BNI groups, Chamber of Commerce events, and local business breakfasts. The office manager sitting next to you at a networking lunch might need a cleaner next month.
- LinkedIn. Search for “facility manager” or “office manager” in your area. Don’t pitch immediately – comment on their posts, share useful content, build the relationship. Then when they need a cleaner, you’re already in their head.
How to make the first approach:
- Lead with a specific observation, not a generic pitch. “I noticed your building has a restaurant on the ground floor – we specialise in commercial kitchen deep cleans and could handle the shared areas too” beats “We offer competitive cleaning rates.”
- Offer a free trial clean or a discounted first month. The risk reversal makes it easy for them to say yes.
Build a Referral Programme That Feeds Itself
Referrals are the highest-converting source of new commercial cleaning clients. A warm introduction from a trusted contact converts at 3–5x the rate of a cold approach. But most cleaning companies leave referrals to chance.
Structure it:
- Offer a specific incentive. “Refer a business that signs a contract and we’ll give you £100 off next month’s invoice” is better than “We appreciate referrals.” Make the reward concrete and immediate.
- Ask at the right time. The best moment to ask for a referral is right after you’ve done something impressive – a flawless deep clean, a same-day emergency response, a glowing inspection result. Don’t wait.
- Make it easy. Give your existing clients a short message they can forward: “Hi [name], my cleaning company [your company] has capacity for another commercial client in [area]. If you know anyone looking, I’d appreciate the intro. They can reach me at [phone/email].”
- Track it. Know which clients refer, how often, and what converts. A simple spreadsheet is enough. Clients who refer once will often refer again if you recognise and reward them.
Harvard Business Review research found that referred customers are 18% more likely to stay with a business and generate roughly 16% more profit. For a recurring cleaning contract, that loyalty compounds.
Use Cold Outreach to Businesses With an Immediate Need
This is the strategy almost nobody in the cleaning industry is using, and it’s the one with the highest conversion rate.
Most cold outreach fails because there’s no timing. You’re emailing a restaurant that’s perfectly happy with their current cleaner, or calling an office that renewed their cleaning contract last month. There’s no reason for them to listen.
But what if you could identify businesses that need a deep clean right now?
The signal: food hygiene failures.
Every food business in England, Wales, and Northern Ireland is inspected and rated by the Food Standards Agency. Ratings run from 0 (urgent improvement necessary) to 5 (very good). When a restaurant scores 0, 1, or 2, it almost always means the premises has cleanliness and structural problems that require professional intervention.
That information is public record. It’s published within days of the inspection. And the restaurant is under regulatory pressure to fix the problems quickly.
A restaurant that just failed its hygiene inspection needs a deep clean today. Not next month. Not when they get around to Googling it. Today.
Why this works:
- The need is real and documented. You’re not guessing whether they need cleaning – a government inspector has confirmed it.
- The timing is immediate. They have a regulatory deadline. This is not a “maybe later” conversation.
- The competition doesn’t know yet. Most cleaning companies are waiting for these businesses to find them. If you reach out within days of the inspection result, you’re first in line.
Across London alone, there are typically 400–500 food businesses rated 0, 1, or 2 at any given time. Each one is a potential deep cleaning contract. Nationally, the numbers are far higher.
How to act on it:
- Check the FSA’s ratings database at ratings.food.gov.uk. Filter by your area and sort by rating.
- Prioritise by urgency: rating 0 first, then 1, then 2. Focus on recent inspections (last 30 days).
- Reach out with a specific message referencing their situation: “I noticed your recent food hygiene inspection result. We help restaurants in [area] get back to a 5 rating with a full commercial deep clean. Happy to discuss what’s involved.”
The response rate on this kind of signal-based outreach is dramatically higher than generic cold calling. The business knows they have a problem, and you’re offering the solution before they’ve started searching for one.
Five Mistakes That Kill Your Chances
These are the errors that keep cleaning companies stuck on the same revenue year after year.
1. Underpricing to win. Competing on price alone is a race to the bottom. Commercial clients care about reliability and quality first. A contract won at unsustainable margins will either kill your profit or force you to cut corners – which loses the contract anyway.
2. No insurance or accreditations. Public liability insurance is non-negotiable for commercial work. Many larger clients also require employer’s liability, COSHH compliance, and DBS checks for your staff. Not having these doesn’t just lose you tenders – it makes you invisible to serious buyers.
3. Weak follow-up. Most cleaning companies send one quote and never follow up. The decision-maker is busy. A polite follow-up three days after your quote, and another a week later, doubles your conversion rate. Use a simple CRM or even a spreadsheet to track every quote and follow-up date.
4. Ignoring your online presence. 83% of cleaning businesses are micro-businesses. Most have no website, no Google reviews, and no online presence beyond a listing on Yell.com. The facility manager who Googles your company name and finds nothing will move to the next quote.
5. Relying on a single channel. If all your work comes from referrals, you’re one lost contract away from trouble. If you only bid on tenders, you miss the faster private sector. The most resilient cleaning businesses run three or four channels in parallel – tenders, local SEO, networking, and proactive outreach.

FAQ
How do I find commercial cleaning contracts near me?
Start with public tender platforms like Contracts Finder and Find a Tender for public sector work. For private sector, use Google Business Profile to attract local searches, network with facility managers, and consider proactive outreach to businesses with a documented cleaning need, like food businesses that have recently failed hygiene inspections.
How much is a commercial cleaning contract worth?
It varies widely by scope. A small office contract might be £300–£500/month. A restaurant deep clean is typically £500–£2,000 as a one-off. A large public sector contract for a school or hospital can be worth £50,000–£200,000+ per year. The key is stacking multiple contracts to build predictable monthly revenue.
Do I need accreditations to win commercial cleaning contracts?
For public sector tenders, usually yes – ISO 9001 and BICSc certifications are commonly required. For private sector work, they’re not mandatory but they build credibility. At minimum, you need public liability insurance and employer’s liability insurance.
What’s the best way to get cleaning clients without cold calling?
Build a strong Google Business Profile with 20+ reviews, create service and location pages on your website, and set up a structured referral programme with existing clients. These three channels generate inbound leads without any cold calling.
How do food hygiene failures create cleaning opportunities?
When a food business scores 0, 1, or 2 on their FSA inspection, it typically means the premises has serious cleanliness and structural problems. The business is under regulatory pressure to fix these issues quickly, and professional deep cleaning is almost always part of the solution. This data is public and published within days of the inspection, creating a window where cleaning companies can reach out before competitors.
How many restaurants fail food hygiene inspections?
Roughly 1 in 10 UK restaurants fall below the minimum standard at any given time. In London alone, there are typically 400–500 food businesses rated 0, 1, or 2 at any point. These numbers refresh constantly as new inspections happen and businesses improve or decline.
