Alta Vision Solar

Search 'find-and-update.company-information.service.gov.uk' for the trading name. Look at incorporation date, current status (Active vs Liquidation/Dissolved), most recent accounts filing, and director list. A long-trading limited company with up-to-date accounts is a safer signal than a recently incorporated firm.

Alta Vision Solar's website (altavisionsolar.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.

Many Greater London-based installers cover a 20–40 mile radius from their base. Alta Vision Solar'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.

London gets enough annual sunlight for a typical 4 kW domestic system to produce roughly 3,200–3,800 kWh/year. Payback periods are typically 8–11 years at current electricity prices. Ask Alta Vision Solar for site-specific yield modelling based on your roof orientation, pitch and shading.

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