What this site is
EPC Upgrade Cost provides independent information, tools and data. Figures are researched, sourced inline, and dated; tools show their assumptions. EPC Upgrade Cost is a free introduction service operated by Ellul Solutions Ltd. We are not energy assessors, installers or solicitors, and nothing here is legal, tax or compliance advice. We are not affiliated with, or endorsed by, any government department, accreditation scheme or enforcement authority named on this site. We pass your details to relevant energy efficiency installers and domestic energy assessors who contact you directly; we may receive a fee from providers, you pay nothing and are under no obligation. Regulatory statements are quoted from published gov.uk guidance and legislation and were checked on the date shown; where a change has been announced but not enacted this site says so, and you should confirm the current position before acting.
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.
