Keenan Electrical and Solar

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

SEG registration is usually handled by your electricity supplier rather than your installer, but Keenan Electrical and Solar should provide the MCS certificate and inverter performance data your supplier will request. Ask Keenan Electrical and Solar whether they walk customers through the SEG paperwork as part of handover.

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 Keenan Electrical and Solar 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.

Per the public business listing, Keenan Electrical and Solar list themselves under: Solar PV Installation, Electrical Services, Energy Equipment Supply. Confirm whether they handle other renewable categories before scheduling a survey. Some London-area installers sub-contract specialist work (e.g. roof structural checks, DNO applications), so ask what's done in-house.
