Rowan Energy

Many Greater London-based installers cover a 20–40 mile radius from their base. Rowan Energy's exact catchment isn't published on EnergyRanked — ask directly. Distance affects scheduling and travel charges; an installer 90 minutes from your property may quote more for the same work than one 20 minutes away.

Rowan Energy's website (rowanenergy.com) 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.

Lead times for Greater London renewables installers swing seasonally — late spring and early summer are peak demand. Ask Rowan 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.

Key questions: panel and inverter brands (and warranties for each); installer MCS number; expected install lead-time; deposit terms and refund policy if cancelled before survey; who handles the DNO application; and roof/structural inspection responsibility. Rowan Energy should answer all of these without hesitation.
