The verdict in three sentences
A 140-operative commercial cleaning contractor in London wins multi-site contracts worth 25,000 to 350,000 GBP a year when a facility manager finds, within five minutes, proof that it masters their exact sector. The effective website displays ISO 14001 and recognised accreditations (CHAS or SafeContractor, BICSc training), one page per sector (food production, cleanrooms, logistics, offices) and a site survey request form instead of a vague 'get in touch'. With Kolonell, the project costs 800,000 to 3,500,000 FCFA (1,220 to 5,340 EUR) depending on the Starter, Growth or Premium tier, delivered in 6 to 8 weeks.
What a facility manager checks before inviting you to tender
The head of facilities for a group running 12 sites across Greater London receives dozens of approaches. They shortlist three to five contractors for each tender, often after a Google search and a LinkedIn check. They look at capacity (headcount, supervision, out-of-hours cover), compliance (right-to-work checks, health and safety policy, insurance), accreditations and comparable references. Many corporate buyers also ask whether you pay the London Living Wage, set at 14.80 GBP an hour for 2026. A site that buries these points in a PDF brochure loses the shortlist.
The sector page is the key, because every environment has its own requirements and contract sizes.
| Sector | Specific requirements | Proof to display | Typical annual contract (2026 order of magnitude) |
|---|---|---|---|
| Food production | Cleaning schedules, HACCP, night shifts | Protocols, food-safe chemicals | 70,000 to 350,000 GBP |
| Cleanrooms | ISO 14644 classes, gowning, traceability | Trained operatives, validated procedures | 50,000 to 220,000 GBP |
| Logistics and warehousing | Large floor areas, scrubber dryers, shift patterns | Machine fleet, output per m² | 35,000 to 160,000 GBP |
| Multi-site offices | Central account management, monthly reporting | Quality audit tool, compliance rate | 25,000 to 130,000 GBP |
| Healthcare and labs | Clinical cleaning, strict protocols | Specific training, audits | 45,000 to 180,000 GBP |
| Post-construction cleans | Short deadlines, waste removal | Before and after photos | One-off, 4,000 to 35,000 GBP |
The site survey form beats an online quote
A cleaning contract cannot be priced online. The right form asks what your sales director needs to prepare the survey: number of sites, floor areas in m², sector, frequency, access hours and the end date of the current contract. That last item is valuable: it lets you schedule follow-up three to six months before renewal. At the end, the prospect picks a survey slot. Such a form qualifies the request and filters out homeowners looking for domestic cleaning.
| Kolonell tier | Budget | Main content | Timeline |
|---|---|---|---|
| Starter | 800,000 to 1,200,000 FCFA (1,220 to 1,830 EUR) | 8 to 10 pages, accreditations, site survey form | 6 weeks |
| Growth | 1,200,000 to 2,000,000 FCFA (1,830 to 3,050 EUR) | Starter + sector pages, filterable references, blog, conversion tracking | 7 weeks |
| Premium | 2,000,000 to 3,500,000 FCFA (3,050 to 5,340 EUR) | Growth + operative recruitment page, site videos, animations, advanced SEO | 8 weeks |
| Client portal with quality reporting | Simple custom application, 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | Quality audits, complaints, invoices per site | Quoted |
| Maintenance | 35,000 to 120,000 FCFA per month (53 to 183 EUR) | Updates, backups, new references | Monthly |
For comparison, a London agency in 2026 typically charges 8,000 to 25,000 GBP for a B2B site at this level, as an order of magnitude.
Hiring and selling with the same website
In cleaning, recruitment often caps growth: a new 130,000 GBP contract can require 8 to 12 extra operatives. A clear careers page with shift patterns, sectors, the hourly rate and a two-minute mobile application also reassures the client: they can see you are able to staff their site. For search, target 'commercial cleaning company London', 'cleanroom cleaning contractor' and 'multi-site office cleaning', supported if needed by monthly SEO.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
James, sales director of a London cleaning contractor, signs 4 new contracts a year today, all through referrals. He aims for 2 extra contracts a year from the website, worth 80,000 GBP each. With an 8 % operating margin, that is 2 × 80,000 × 0.08 = 12,800 GBP a year, or 38,400 GBP over 3-year contracts. The Premium site costs at most 5,340 EUR and Standard maintenance 75,000 FCFA a month (114 EUR), so 1,368 EUR a year. Over three years the total investment is 9,444 EUR, set against 38,400 GBP of margin: the website is repaid several times over, and the first contract alone covers it.
FAQ
Should we publish cleaning rates?
Not for multi-site contracts: price depends on floor area, frequency and access hours. Show benchmarks instead, such as 200 to 300 m² per hour in offices, and offer a free site survey.
How should we showcase accreditations?
With a block visible on every page showing logos, renewal dates and a link to certificates. A buyer comparing 5 contractors often drops those who do not show them.
How many references should we publish?
Ten to fifteen are enough if they can be filtered by sector, with floor area, number of sites and length of relationship. A client retained for 7 years is worth more than a long wall of logos.
Can the site help with tender responses?
Yes, a downloadable pack with certificates, insurance and staffing capacity saves 1 to 2 hours per bid. Public sector buyers also find your named contact there.
How long until we rank for London searches?
Allow 3 to 6 months for local sector searches. Sector pages often rank faster than the homepage because they match a precise intent.
