UK solar panel adoption by local authority (installations per 1,000 households): HIGHEST ADOPTION: Devon (85/1,000), Cornwall (82/1,000), Somerset (78/1,000), Dorset (75/1,000), Wiltshire (72/1,000). South-west England dominates — more sunshine, larger properties, rural off-gas homes driving adoption. LOWEST ADOPTION: Tower Hamlets (8/1,000), Camden (10/1,000), Hackney (11/1,000), Islington (12/1,000), Lambeth (14/1,000). Inner London lags due to: flats (no roof access), conservation areas, listed buildings, rented properties. NATIONAL AVERAGE: 47 installations per 1,000 households. METHODOLOGY: MCS certified installation data (mcscertified.com/mcs-data-dashboard) by postcode, mapped to local authority boundaries, divided by ONS household count (ons.gov.uk). PATTERN: adoption correlates strongly with (1) property type (detached > semi > terrace > flat), (2) tenure (owner-occupied > private rented > social rented), and (3) household income (higher income = higher adoption). The solar equity gap is real — but declining as costs fall and grant programmes expand.

Solar panels are most powerful when combined with an efficient heating system. Heat pumps use solar-generated electricity to heat your home at 300-400% efficiency — making them the ideal partner for solar.
Heat pump installation typically takes 2-3 days and is best planned alongside solar.
