Robinz Electrical provides NAPIT-registered electrical inspection and testing for homeowners, landlords, letting agents and business owners across Hertfordshire. Our electricians check your wiring, consumer unit and circuits against BS 7671, record every fault they find and explain what needs fixing in plain English.
You then receive a full Electrical Installation Condition Report (EICR) that you can use for your insurer, tenants, letting agent or mortgage lender.

Wiring wears out over time, and many faults are hidden behind walls, in the consumer unit or in the loft. An electrical inspection finds problems before they cause shocks, fires or damaged appliances, and gives you written proof that your installation is safe.
Every observation in your EICR is given a code:
| Code | Meaning | What happens? |
|---|---|---|
| C1 | Danger present | Immediate action is needed. We make the problem safe straight away. |
| C2 | Potentially dangerous | Urgent remedial work required. |
| C3 | Improvement recommended | Not dangerous now, but worth improving. |
| FI | Further investigation is required | Something couldn't be fully checked and needs a closer look. |
A report with any C1, C2 or FI code is classed as unsatisfactory until the work is done. A report with only C3 observations (or none) is classed as satisfactory.
You receive a full EICR for your insurer, tenants, letting agent or lender, showing the condition of your installation, any coded faults and a recommended date for the next inspection. Certificates are issued on completion, and if remedial work is carried out, we issue the correct certificate for that work.
An EICR checks fixed wiring. We also carry out:
We provide both for landlords, HMOs and businesses. If you're not sure which your premises need, read EICR vs PAT testing for businesses.
Our EICRs start from £150. The final price depends on the property's size and the number of circuits, and we give you a free, no-obligation quote before we start, with no hidden extras.
We're a family-run business, not a call centre. When you ring, you speak to the electricians who will do the work and stand behind it. Read more about our family-run team.
We're NAPIT registered (no. 84444), TrustMark registered (no. 4219929) and fully insured, with £2 million public liability and £250,000 professional indemnity cover. Our electricians are City & Guilds qualified, and we're members of the IET.
Every inspection and every job is completed to the current wiring regulations. You get a clear report or certificate with nothing left vague.
We tell you what we found, what it means and what it will cost before any work starts. Quotes are free and come with no obligation or pressure.
We're based in Knebworth and have been working across Hertfordshire since 2023. Planned work is booked Monday to Friday, 9 am to 5 pm, and we're on call 24/7 for genuine emergencies. Installations come with a 1-year guarantee plus an extended product warranty, and if you're not happy we'll do everything we can to put it right.

Every job is carried out by qualified electricians who test their own work, issue the right certificates and clean up before they leave. See all our electrical services.
Tripping circuits, flickering lights and dead sockets point to a fault somewhere. We find it with proper test equipment, tell you what it is and quote before we start. More on repairs and fault finding.
Older fuse boards often lack modern protection. We replace them with a consumer unit fitted with RCDs, then test and certify the work, which reduces the risk of electric shock and fire. Read about fuse board upgrades.
We carry out full and partial rewires and add circuits for extensions, kitchens and garages. We keep mess and disruption low, then test and certify our work to BS 7671. Wondering whether you need one? Read how to tell if a house needs rewiring.
We fit new lights and replace old ones, indoors and outdoors. We agree the layout with you first and use quality fittings. LED options can also cut your energy bills. See lighting installations.
Need more sockets, USB outlets or different switches? We fit new ones, replace worn ones and move existing ones, with safe connections and neat finishes that suit your existing decor.
We look after shops, offices, warehouses and other commercial premises with installations, maintenance, emergency lighting and compliance testing. We schedule work around your opening hours so your business keeps running. See commercial services.
Electrical faults don't wait for office hours, so we're on call 24 hours a day, 7 days a week for genuine emergencies. We make the situation safe straight away, then arrange a proper repair.
Call 07383 035007.
Safety first: if you see flames or smoke, or if someone has been electrocuted, call 999 before calling us. If you smell burning, switch off the power at the consumer unit if it is safe to do so and don't use the affected circuit.
We support developers, builders and property owners from first plans to final certification. You get clear updates, realistic timetables and reliable delivery, so your project stays on track.
We install first fix and second fix wiring, distribution boards, lighting and power for new homes and extensions. We work alongside other trades so each stage finishes safely and on time.
Renovating an older property? We upgrade ageing wiring, add circuits and install new lighting, working around your existing finishes. Everything is tested and certified, so it is safe to use.
Before work begins, we work with you to prepare:
We then coordinate each stage so the work follows your programme.
We deliver electrical fit-outs for offices, shops, restaurants and industrial units, including lighting, power and data points. We work closely with your programme so you can open as planned.

Wiring wears out over time, and faults are often hidden. An inspection finds those problems early and gives you written proof of safety for insurers, lenders and tenants.
Private landlords in England need one at least every five years, and before a new tenancy if the last report is older. Homeowners are usually advised to have one every ten years and when buying or moving into a property. Commercial premises are typically inspected every five years.
We inspect and test your circuits, sockets, switches, lighting and consumer unit against BS 7671. We switch the power off for short periods during testing. We explain our findings before we leave and send you the full report afterwards.
Most homes take 1 to 3 hours, depending on the size of the property and the number of circuits. Larger or commercial properties take longer, and we'll tell you what to allow when we quote so you can plan around the power being off for short periods.
Our EICRs start from £150. The final price depends on the property size and the number of circuits, and we always give a free, no-obligation quote first, with no hidden extras.
Each fault is coded C1, C2, C3 or FI. We explain what each one means, quote for any remedial work and complete it promptly if you'd like us to. A report with any C1, C2 or FI is unsatisfactory until the work is done.
You'll receive a full EICR showing the condition of your installation, any coded observations and the recommended date of your next inspection. Certificates are issued on completion, including for any remedial work we carry out.
An EICR checks your fixed wiring, such as circuits, sockets and your consumer unit. PAT testing checks portable plug-in appliances. We carry out both, as well as emergency lighting testing.
Yes. We provide EICR, PAT and emergency lighting testing for homeowners, landlords, HMOs and businesses.
It isn't a legal requirement for most home sales, but buyers, surveyors and lenders sometimes ask for one, and having a recent report can avoid delays.
