Terms of use
What this site is
TM44 Quote provides independent information, tools and data. Figures are researched, sourced inline, and dated; tools show their assumptions. TM44 Quote is a free introduction service operated by Ellul Solutions Ltd; we pass your details to accredited air conditioning energy assessors who quote you directly. We may receive a fee from providers; you pay nothing and are under no obligation. This is an independent guide, not affiliated with or endorsed by CIBSE, and not affiliated with MHCLG, the Energy Performance of Buildings Register or any accreditation scheme. Nothing here is legal advice: gov.uk states that any interpretation of the regulations is offered only as a guide and that independent legal advice should be sought in cases of doubt. Statutory figures were read from gov.uk on 14 August 2026 and apply to England and Wales.
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.
