Every number has a named source
Each figure on our pricing and research pages carries a footnote to a source listed at the foot of that page, with the publisher, the year and a link. If we cannot source a number, we do not publish it.
How we publish
Editorial standards
Our buyer resources and sector guides are company-published editorial guidance with linked sources and content-review dates. Pricing pages provide externally published market context, not our quotations. We distinguish source synthesis from first-hand evidence and disclose our commercial interest in facilities management enquiries.
Ranges are indicative, not quotations
Published market ranges exist so you can budget and sanity-check a bid. They are not our prices. A quotation depends on floor area, service mix, hours of cover, asset condition and site count, and we scope those before we price anything.
We do not average away disagreement
Where two credible sources give different ranges, we show both rather than blend them, because the underlying specifications differ. Wide ranges in this market are honest; a single precise figure usually is not.
Company authorship, not invented experts
Guidance is published under the company name. Company authorship does not imply a named professional reviewed the page, a particular qualification or first-hand inspection of every provider discussed. We do not invent author personas or attribute credentials to unnamed writers.
Commercial interest and provider comparisons
We sell facilities services and have a commercial interest in enquiries. The updated sector guides are procurement guidance, not independent league tables or audits of competitors. A useful scope, relevant competence evidence and permission-backed references matter more than an unsupported ranking. No client outcome is invented to support those guides.
Dated and reviewed
Pricing and research pages show a last-reviewed date. Cost data in this market moves with wage settlements and energy prices, so a figure without a date is not usable — ours carry one, and we revisit them when the underlying sources update.
Corrections
If you find a figure you believe is wrong or out of date, email info@pearllemongroup.com with the page and the source you are using. We will check it against the publisher and correct the page if it is wrong.
Publishers we currently cite
The full citation, with year and link, sits on each pricing or research page. Buyer resources link to official guidance for the relevant context. A source being available does not prove that its commercial ranges represent every building or an independent market sample.

Editorial responsibility and limits
Our company page identifies the publisher. New buyer resources link official guidance and state their review date. Procurement checklists do not establish legal compliance or replace competent advice for your premises. Reports summarise cited material; they are not a survey of our clients or original field research unless a method and dataset are explicitly supplied.
