What we do

Seven services, one accountable team

Because we cover power, wiring, security, automation and connectivity in-house, we can quote a whole site as a single job instead of leaving you to coordinate four contractors.

How it works

Six steps from first call to handover

No mystery in the middle. You always know who is on your site, what they are doing, and what it costs.

  1. Enquiry

    Call, WhatsApp or send the form. Tell us the site and what you want solved — two minutes is enough to start.

  2. Site survey

    We visit, measure and test. Load readings, shading, cable routes and fence perimeters all get checked in person.

  3. Written quote

    A fixed, itemised quote with equipment specified by brand and model. No vague line items, no surprises later.

  4. Installation

    Our own trained crews install and test on the agreed dates. One supervisor, one job file, no subcontracting.

  5. Handover

    We commission the system, train your people on the apps and hand over certificates, manuals and warranty papers.

  6. Aftercare

    Scheduled servicing, remote support and emergency callouts. Faults get fixed by the same team that installed the work.

Why Trewbless

Built on work we stand behind

Everything below is a promise we can put in the contract.

We install it ourselves

No subcontractors. The people who survey your site are the people who wire it, and the people who wire it stand behind the warranty.

Fixed written quotes

Itemised pricing with named brands and models before any work starts. If the job changes scope, you approve the change first.

One crew, whole site

Solar, wiring, CCTV, access control, smart home automation and fencing coordinated together — one mobilisation, one schedule, one point of contact.

Aftercare is not optional

Scheduled maintenance and emergency callouts are part of the relationship, not an upsell we hope you forget about.

FAQ

Questions we get asked a lot

Yes. We travel across Nigeria for larger installations — solar arrays, electric fencing and CCTV on estates. Smaller jobs outside our base are scheduled in regional batches so you are not waiting weeks for a technician.

Most residential solar systems are installed in one to two days once equipment has landed. Grid-tie approval from your DisCo and NERC can take longer, but you keep using your existing supply in the meantime.

Yes. Our NVR systems record locally and keep recording if your connection drops. Remote viewing needs data, and where there is no fixed line we fit 4G cameras instead.

Energizers carry a manufacturer warranty of up to five years, and our workmanship is guaranteed for two years. We also return for the first service visit within the warranty period.

For solar, CCTV and electric fence work, yes — a free site survey is part of the quote. We can give a ballpark figure over the phone first so you know whether it is worth having us look.

Often, yes. Because we handle solar, electrical and access control, a new build or farm upgrade can be quoted as a single package with one mobilisation charge instead of several contractors.

Yes. We install and link the locks, lighting and climate control to Alexa or Google Home and build the routines so one command runs a whole scene. We also set fail-safes on doors, so a flat battery or dropped Wi-Fi never leaves you locked out — the keypad and physical key always still work.
