How this page was calculated
If the calculated sound pressure level at all assessment positions is equal to or lower than 37.0 dB(A) then the heat pump will comply with the Permitted Development noise limit Estimated by MCS 020a Issue 1.1 for one unit, Q=2, no barrier, via contract_engine. £ per summer is capacity ÷ SEER × hours × 26.32p/kWh (2026-10-01 to 2026-12-31). The pair row lives in the compare index CSV.
Open the two cards
Better than a spec-sheet glance: the gap is scored at the same distances against the 37 dB line, and £ per summer uses one tariff.
