Frequently asked questions
How long is the typical wait for an install with J&J CRUMP & SON LTD?
Lead times for South Yorkshire renewables installers swing seasonally — late spring and early summer are peak demand. At time of indexing the public Google listing showed 75 reviews at 3.9★, which gives some indication of throughput. Ask J&J CRUMP & SON LTD 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 J&J CRUMP & SON LTD offer free site surveys before quoting?
Most reputable UK installers — including most Sheffield-area firms — offer a free desktop survey followed by a paid or no-cost roof inspection. J&J CRUMP & SON LTD's specific policy isn't published on EnergyRanked; ask when you make initial contact (their website jjcrump.com is a useful starting point). A red flag would be any installer quoting without ever physically seeing the roof or property.
Is J&J CRUMP & SON LTD registered with RECC or HIES?
RECC (Renewable Energy Consumer Code) and HIES (Home Insulation & Energy Systems) are the two main consumer protection codes for UK renewables installers. Check the RECC register at recc.org.uk or HIES register at hies.co.uk by company name. Membership of either gives you escalation routes and deposit protection.
What warranty does J&J CRUMP & SON LTD typically offer?
UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years. Ask J&J CRUMP & SON LTD specifically what's covered, who underwrites it, and what happens if they go out of business (an MCS Insurance Backed Guarantee — IBG — covers this scenario).
Does J&J CRUMP & SON LTD cover areas outside Sheffield?
Many South Yorkshire-based installers cover a 20–40 mile radius from their base. J&J CRUMP & SON LTD'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.
