Click any 'Request an Estimate' button on our website to fill in our short estimate form. Alternatively, call or WhatsApp us directly. We respond within 24 hours with a detailed, no-obligation quote.

Yes. All estimates are completely free and carry no obligation whatsoever. We provide a full written quote before any work begins — you are never charged simply for asking.

For standard residential projects we aim to provide a quote within 24 hours. For larger commercial or customised projects that require a site visit, we typically provide a detailed proposal within 3–5 business days.

Yes, in almost all cases. We price our jobs thoroughly upfront. If unforeseen issues are discovered during the work — for example, hidden wiring faults in older properties — we will always discuss any potential additional costs with you before proceeding.

Yes. For larger projects such as solar PV installations, we work with partners to offer flexible payment arrangements. Contact us to discuss the options available for your specific project.

It helps to have a rough idea of the service you need, the size and type of your property, and your location. For solar projects, your average monthly electricity bill is also useful. We'll ask the right questions to gather everything else we need.

A solar PV system converts sunlight into electricity using photovoltaic panels mounted on your roof or ground. The generated DC electricity is converted to AC by an inverter, making it directly usable in your home or business. Excess electricity can be stored in batteries for use at night or during outages.

System costs vary based on size, type and complexity. A typical residential off-grid system ranges from XAF 1.5M to XAF 6M. We provide free, detailed quotes tailored to your specific energy needs and budget.

A grid-tied system is connected to the national grid and uses it as a backup — lowest upfront cost but no protection during power cuts. An off-grid system uses batteries for complete energy independence — ideal where grid supply is unreliable. A hybrid system combines both — grid connection plus battery storage for maximum resilience.

Most residential solar PV installations are completed in 1–3 days. Larger commercial systems may take longer depending on scale and site conditions. We provide a clear timeline before starting.

With a hybrid or off-grid system, stored battery power is used when solar generation is low. Grid-tied systems draw from the national grid at night or on heavily overcast days.

Quality solar panels are rated for 25–30 years and typically carry a 10–12 year product warranty and a 25-year performance warranty. We use tier-1 manufacturers with proven long-term track records.

Most of our residential solar clients see electricity bill reductions of 60–100% depending on system size and usage patterns. We provide detailed savings projections with every proposal.

Yes. We guide you through the full permitting process and handle all technical documentation on your behalf — you don't need to worry about any of the paperwork.

A typical 3-bedroom home rewire takes 5–7 days. Larger properties or those with complex layouts may take slightly longer. We provide a detailed timeline before starting any work.

Not necessarily. For partial rewires or smaller jobs, you can usually remain in the property. For a full rewire, it is often more practical to be away, but this depends on the size of your home and the scope of work. We'll advise on the best approach for your specific project.

Yes. All electrical installations must be tested and certified. We provide a full Electrical Installation Certificate (EIC) on completion of every job — this is also a requirement for insurance and property sales.

Key warning signs include frequently tripping circuit breakers, flickering lights, burning smells from sockets or switches, discoloured outlets, a fuse box that still uses old ceramic fuses, and wiring that is more than 25 years old. If you notice any of these, contact us for a safety inspection.

Yes. We install home and commercial EV charging points. We'll assess your existing electrical supply and recommend the right charger type and installation approach for your property.

Yes. We carry out full Electrical Installation Condition Reports (EICR) for homeowners, landlords and businesses — providing a detailed assessment of your electrical system's safety and any remedial work required.

This depends on your property size, layout, number of entry points and security goals. We carry out a free site survey to assess blind spots and security risks, then recommend the optimal number and placement of cameras for your specific property.

Yes. All our IP camera systems support remote viewing via a smartphone app — available on both iOS and Android. You can check your cameras from anywhere in the world with an internet connection.

Storage duration depends on the number of cameras and the hard drive capacity of your recorder. We typically configure systems to store 30 days of continuous footage. Cloud storage options are also available for additional redundancy.

We work with industry-leading brands including Hikvision, Dahua, Uniview and Axis — all chosen for long-term reliability, comprehensive after-sales support and proven performance in real-world conditions.

Yes. We design and install integrated security systems that combine CCTV, intruder alarms, access control and electric fencing — all managed from a single platform where required.

Yes. We offer three tiers of maintenance cover — Annual Service (one visit per year), Full Cover (two visits plus unlimited call-outs), and Enterprise Managed Support for businesses with multiple systems or sites. Contact us for a tailored quote.

For clients on a Full Cover or Enterprise support contract, we guarantee a maximum 4-hour response time. For non-contract clients, we aim to attend within 24 hours subject to location and availability. Emergency calls can be made 24 hours a day, 7 days a week.

Yes. We service and maintain electrical, solar, CCTV and air conditioning systems regardless of who installed them, subject to an initial condition assessment.

A standard annual service includes a full visual inspection, electrical safety testing, cleaning of all accessible components, performance checks, firmware updates where applicable (smart systems), and a written condition report with any recommended remedial actions.

Call us on +237 671 148 803 or send a WhatsApp message at any time of day or night. Our team will assess the situation and dispatch an engineer as quickly as possible.

AC sizing depends on room size, ceiling height, insulation quality, sun exposure and occupancy. Our engineers calculate the correct BTU rating to ensure efficient and effective cooling — an undersized unit wastes energy and an oversized one causes humidity problems.

We recommend servicing your AC system at least once a year — ideally before the hot season begins. Regular servicing extends system life, maintains efficiency and prevents costly breakdowns.

A single split-system AC unit can typically be installed in 3–5 hours. Larger multi-zone or ducted systems may take 1–2 days depending on the complexity of the installation.

Our engineers are trained on all major brands including Daikin, Mitsubishi Electric, LG, Samsung, Gree, Midea and Hisense. We recommend the most suitable brand and model for your budget and usage requirements.

Yes. We diagnose and repair all types of AC faults — from refrigerant leaks and compressor failure to electrical faults, frozen coils and remote control issues. We carry a comprehensive stock of common spare parts.
