Who It's For

Who we build for.

Commercial installation is about programs, compliance and coordination — here's how we fit your project.

Builders & developers

Priced from drawings, booked to program, staged around your trades — with handover docs your certifier actually wants.

Tenancy fit-outs

Shops, offices and clinics — installed around landlord requirements, base-building services and your opening date.

Retail & hospitality

Front-of-house comfort, back-of-house refrigeration and kitchens that don't cook the staff — often installed after hours.

Industrial

Workshops, warehouses and plant rooms: ventilation, evaporative and mechanical services engineered for the real workload.

How It Works

Tender to handover, no surprises.

A commercial install that runs like a program line — because it is one.

Plans & pricing

Send drawings or walk us through the site — we return a detailed, itemised price with options and lead times.

Design & coordination

Equipment selections, services coordination and program dates locked in with your supervisor before anyone's on site.

Staged installation

Rough-in, fit-off and commissioning staged to your build — after-hours and weekend works where trade can't stop.

Commissioning & handover

Tested, balanced and documented: commissioning data, electrical certificates and warranty registration in one pack.

Good To Know

Commercial installation FAQs

The questions builders and business owners ask before they engage us.

Can you work to a builder's program?

Yes — we quote from your drawings, book to your program and stage works around other trades. Rough-in, fit-off and commissioning are scheduled as separate visits where the build calls for it, and we keep the site supervisor in the loop the whole way.

Do you provide compliance and handover documentation?

Every commercial installation is handed over with commissioning data, compliance certificates for the electrical work and manufacturer warranty registration — everything your certifier and your client need in one pack.

Can installations be done after hours?

Yes. For trading businesses we regularly install nights and weekends so you don't lose a day of trade. After-hours works are priced into the quote up front — no surprises.

Who handles the electrical side?

We do. Doylair is led by a certified electrician, so power supply, isolators and controls wiring are done in-house to standard — one contractor, one point of responsibility.

"Despite my tricky air conditioning setup, he took the time to explain everything and was happy to tackle the difficult job. Philip's 'no job is too hard' attitude stood out."
