Sol4r Energy

Most reputable UK installers — including most London-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. Sol4r Energy's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website sol4renergy.co.uk is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.

Use the phone number and email on the listing page above, or visit their website (sol4renergy.co.uk). For initial enquiries, email tends to give you a written paper trail; for an urgent quote, phoning often gets a faster site survey booking.

Demand peaks April–August across the UK. Booking in autumn or winter often means shorter waits and sometimes pricing flexibility. Installation itself is a year-round activity in most UK weather — the constraint is scheduling, not the season.

Lead times for Greater London renewables installers swing seasonally — late spring and early summer are peak demand. Ask Sol4r Energy directly for current scheduling once you've got a written quote. Plan for 4–12 weeks from deposit to install on a typical residential project; complex roofs or DNO upgrades can extend that.

Sol4r Energy's website (sol4renergy.co.uk) typically lists their service categories, recent case studies, panel and inverter brands they install, and contact details. Cross-check against their Google listing — discrepancies between the two are a useful sanity check.
