The verdict in three sentences
For a commercial cleaning company in London, a GBP 3,000 landing page (about EUR 3,500) is the right choice if 80% of your enquiries come from Google Ads and you sell a single service. Once you target several services (offices, windows, post-construction, residential blocks) and several areas (Canary Wharf, Croydon, Hammersmith), the 12-page website at GBP 7,000 becomes more profitable because it captures free traffic and lowers cost per lead. With B2B contracts worth GBP 900 to 3,500 a month, a single signed client pays back either option.
Two tools, two logics
A landing page is a single page built to convert paid visitors: clear promise, proof (accreditations, references, insurance), a short quote form and a click-to-call number. It converts well, often 8 to 12% of qualified Ads traffic, but barely ranks in organic search.
The 12-page website adds service pages and area pages. Each targets a precise query, such as "office cleaning Canary Wharf" or "post-construction cleaning London", and can serve as a better-targeted Ads landing page, which improves Quality Score and reduces cost per click.
| Criterion | Landing page | 12-page website |
|---|---|---|
| 2026 price | GBP 3,000 | GBP 7,000 |
| Time to launch | 1 to 2 weeks | 4 to 5 weeks |
| Target conversion rate (Ads traffic) | 8 to 12% | 6 to 10% on service pages |
| SEO traffic after 6 months | Near zero | 300 to 900 visits/month (estimate) |
| Pages per service and area | No | 4 services, 4 areas |
| Google Ads cost per lead | GBP 30 to 55 | GBP 25 to 42 thanks to targeted pages |
| Credibility with a facilities manager | Medium | Good (references, process, accreditations) |
The calculation that settles it
Reason over 12 months in total acquisition cost. Assumption: a Google Ads budget of GBP 1,500 a month and a 15% close rate on qualified leads.
| 12-month indicator | Landing page | 12-page website |
|---|---|---|
| Build cost | GBP 3,000 | GBP 7,000 |
| Annual Ads budget | GBP 18,000 | GBP 18,000 |
| Average cost per lead | GBP 42 | GBP 34 |
| Ads leads | 428 | 529 |
| SEO leads (months 4 to 12) | 10 | 60 |
| Contracts signed (15%) | 66 | 88 |
| Acquisition cost per contract | GBP 318 | GBP 284 |
These are 2026 orders of magnitude. They show a simple point: the GBP 4,000 gap at build time is recovered as soon as the site generates a few free leads and targeted pages cut cost per lead by GBP 5 to 10. Conversely, if you are testing a new market for 3 months, the landing page remains the best option, with a full site later. For comparison, the same choice in Toulouse, France is EUR 1,500 versus EUR 4,500.
Mini case study
Mark, owner of a London office cleaning company with 35 operatives and GBP 1.6 million turnover, picks the 12-page site at GBP 7,000 with GBP 1,500 a month in Google Ads. Over 12 months he signs 9 new contracts attributable to the site, averaging GBP 1,800 a month with a typical 3-year term. In year one alone, counting 6 months of billing on average per contract, that is 9 × 1,800 × 6 = GBP 97,200 in revenue. At an 8% net margin, that yields about GBP 7,800, covering the site and part of the Ads budget in year one, before years 2 and 3 of those contracts.

FAQ
Can we start with a landing page and move to a website later?
Yes, it is a sound test strategy. The GBP 3,000 landing page can be reused as an Ads landing page inside the future site, so the initial investment is not lost.
How many area pages should we create?
Three to five high-potential areas are enough to start, for example the City, Canary Wharf, Croydon and Hammersmith. Each page needs genuinely local content, or Google treats it as duplicate.
What conversion rate is realistic?
For B2B cleaning, 6 to 10% of qualified Ads visitors fill in a form or call. Aiming for 8% is realistic with a 4-field form and a click-to-call number on mobile.
Should we show prices on the site?
An indicative hourly rate (for example from GBP 22 per hour) filters out low-quality enquiries. The final quote is issued after a site visit.
What proof reassures a facilities manager?
Accreditations (CHAS, SafeContractor, ISO 14001), insurance certificates, 3 to 5 client references and a description of quality control. In our experience these lift conversion by 15 to 30%.
