Terms of use
What this site is
Noise Assessment Cost provides independent information, tools and data. Figures are researched, sourced inline, and dated; tools show their assumptions. Noise Assessment Cost is a free introduction service operated by Ellul Solutions Ltd; we pass your details to relevant acoustic consultants who quote you directly. We may receive a fee from providers; you pay nothing and are under no obligation. We are not an acoustic consultancy and nothing here is professional or legal advice, fee figures are typical 2026 quote ranges that vary by region, monitoring duration and complexity. BS 4142 and BS 8233 are named for identification only.
What this site is not
Nothing here is financial, legal, tax, medical or other regulated advice, and no tool output is a quote, an offer, or a recommendation to act. Results are estimates from the stated assumptions; confirm anything that matters with a qualified, authorised professional before acting. Where we introduce you to a provider, we act as an introducer only: we do not advise on, arrange, or recommend between providers, and we never handle client money.
Accuracy and liability
We work to keep every figure current (each table shows its last-updated date) but make no warranty that content is error-free. To the extent permitted by law, Ellul Solutions Ltd accepts no liability for loss arising from reliance on this site. Links to external sites are provided for sourcing; we are not responsible for their content.
Embedding and citation
You may cite this site's data with attribution (a link to the page cited) and may use the embeddable widget where offered, unmodified. Scraping that removes attribution, or republishing tables wholesale without a link, is not permitted.
