Frequently asked questions
Are there other solar installers in Plymouth I should compare?
Yes — three quotes is the UK standard. Use EnergyRanked's Plymouth filter to compare Callidus Trade against other local installers on rating, review count, and accreditation. Don't just chase the cheapest quote; compare warranty terms and brand specs side-by-side.
When is the best time to book a solar install with Callidus Trade?
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.
Does Callidus Trade offer Insurance Backed Guarantees (IBG)?
An IBG is essential — it covers the workmanship warranty if the installer ceases trading. MCS-certified installers usually offer IBG via the MCS scheme. Confirm Callidus Trade provides an IBG certificate at handover; don't accept a workmanship guarantee that's only as good as the installer's continued existence.
How long is the typical wait for an install with Callidus Trade?
Lead times for Devon renewables installers swing seasonally — late spring and early summer are peak demand. At time of indexing the public Google listing showed 412 reviews at 4.9★, which gives some indication of throughput. Ask Callidus Trade 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.
Does Callidus Trade handle Smart Export Guarantee (SEG) registration?
SEG registration is usually handled by your electricity supplier rather than your installer, but Callidus Trade should provide the MCS certificate and inverter performance data your supplier will request. Ask Callidus Trade whether they walk customers through the SEG paperwork as part of handover.
