The Working Class Quality System: 12 mandatory quality pillars, dual QA verification, ISI/BIS material guarantee, and tiered 30/60/90 day workmanship warranty across every home and commercial service we deliver. 2 lakh+ jobs completed with a 98.2% first-time fix rate.
40% of home service jobs performed by unregistered local operators in Coimbatore and Tiruppur require re-work within 30 days. We built the Working Class Quality Stack to eliminate that number for every single customer.
Quality is not an afterthought in home services — it is the entire product. In Coimbatore and Tiruppur, fly-by-night operators lure customers with rock-bottom prices only to cut corners on material, skip testing, and disappear the moment a fault reappears. Independent surveys across Tamil Nadu confirm that nearly 40% of all home service jobs require re-work within 30 days when performed by unregistered local handymen. Working Class was built specifically to solve this problem. Every service we deliver, from a simple socket replacement in Ukkadam to a full 3-phase textile factory installation in Avinashi, passes through the same mandatory quality gates with zero exceptions. We do not cut corners, we do not rush sign-offs, and we do not mark a job complete until it passes both our standards and yours.
The Working Class Quality Stack is our proprietary four-layer system. Layer one: the 100-point digital job completion checklist, customized by service category, where every checkbox must be verified with photo evidence before completion is even offered. Layer two: dual quality assurance — the executing technician self-audits every task, then 20% of all jobs (and 100% of high-value/commercial jobs) receive a spot-check by an independent supervisor before the customer is invited to sign off. Layer three: before/after photographic evidence of every key stage, timestamped and geo-tagged, uploaded to your job record for permanent traceability. Layer four: our tiered 30/60/90 day workmanship warranty backed by a 24-hour free revisit SLA for any in-warranty fault reported anywhere in Coimbatore or Tiruppur.
Quality is only credible when it is local. Our Coimbatore and Tiruppur quality operations are not managed from a distant Bangalore call center — they are managed on the ground by a 68-member strong local quality team. Our Coimbatore HQ quality desk in RS Puram covers 10 zone-based quality hubs staffed by 32 field supervisors who perform daily on-site audits across the city. Our dedicated Tiruppur quality office on Avinashi Road runs 6 zone desks specifically optimized for textile, export, and industrial customers — with supervisors who understand the cost of a single hour of production downtime in a knitting shed. Both offices run daily quality huddles, publish weekly audit scorecards, and escalate any 48-hour-unresolved complaint directly to the Quality Head for resolution.
Transparency is the foundation of trust. Every NPS survey response we receive — the glowing 10s and the frustrated 3s alike — is published verbatim on our public reviews dashboard with no filtering, no cherry-picking, and no reply-gating. Every complaint ticket opened against our quality standards is traceable by the customer through a unique ticket ID, with full visibility of assigned owner, SLA deadline, and resolution notes. We do not hide our mistakes; we fix them, measure them, and train against them. Our monthly quality reports, including first-time fix rate trends, supervisor audit pass rates, and re-work breakdowns by category, are available to any customer who requests them.

Following these simple quality-protection steps ensures you catch issues early and get the full value of our warranty.
Before the technician opens any sealed packet of material, ask to see the brand name and ISI/BIS hologram stamp. Cross-check against the itemized quote shared with you on WhatsApp.
After any installation (fan, light, geyser, switchboard, tap, etc.), always ask the technician to run a full live test of every function — every speed, every switch, every mode — in front of you.
The digital job sheet sent to your WhatsApp and email is your proof of warranty. Save it. It lists technician ID, material ISI numbers, warranty period, and completion date.
Your honest NPS rating and open-text feedback directly trigger quality improvements. A low score with detailed comments gets an immediate quality desk review — not ignored.
Warranty claims reported within the first 24 hours after sign-off are resolved 3x faster. Do not wait for a small issue to become a larger fault — report immediately via WhatsApp.
After a great experience, note the technician ID. Returning customers can request a specific verified high-rated professional for future bookings at no extra cost.
Before entering the OTP, ask the technician to show you the completed 100-point digital checklist on their app. Each item should have a photo or reading attached.

Refund decisions are documented with reasons and logged in our quality system.
We guarantee that every single piece of electrical, plumbing, or construction material supplied under the Working Class brand is ISI/BIS-marked where a standard exists and is sourced directly from brand-authorized distributors. If any material supplied is found to be counterfeit or non-ISI, we replace it free of charge and compensate the customer at 2x the material value under our Zero Counterfeit Policy.
