About Robinz Electrical in Knebworth

We are Robinz Electrical, a family-run team based in Knebworth. Homeowners and businesses in Woolmer Green, Stevenage, Hertfordshire, Bedfordshire and Essex call us for lighting, fuse boards, inspections, rewiring, repairs, fault finding and emergency help day or night. We arrive on time, work tidily and stand behind every job.

Why you need a professional electrical fault finding service

Most electrical faults give you a warning before they turn serious. A breaker that keeps tripping, a socket that has gone dead, lights that flicker or a faint burning smell near a fitting all point to a problem somewhere in the wiring. Resetting the switch and carrying on only hides it. A qualified electrician tests the circuit, finds exactly where the fault is and puts it right before it becomes dangerous or expensive.

  • Safety: loose connections, damaged cables and worn insulation can overheat, cause shocks or start a fire.
  • The right fix first time: proper testing finds the real cause, so you do not pay for guesswork.
  • Smaller bills: a minor fault caught early costs far less than the damage it causes later.
  • Proof of a job done properly: repairs are completed to BS 7671 with certification supplied, which landlords, insurers and buyers often ask for.

How we find electrical faults

We start by asking when the problem happens and what was in use at the time. We then isolate each circuit and test it, checking insulation, continuity and RCD operation until the fault is pinned down. Overloaded circuits, loose connections, faulty appliances, damp and ageing wiring are the causes we meet most often.

What to do until we arrive

  • Do not keep resetting a breaker that trips again straight away.
  • Unplug the appliances on the affected circuit.
  • Make a note of when it happens and what was switched on at the time.
  • Never open a socket or consumer unit yourself.
  • If you see smoke or flames, call 999 first.

FAQs

Electrical fault
finding FAQs

01What electrical services do you offer in Hertfordshire?

We provide lighting installation, fuse board upgrades, EICR and PAT testing, rewiring, new circuits, sockets and switches, and commercial electrical work. We also offer electrical fault finding, electric repairs and 24/7 emergency call outs for homes and businesses across Hertfordshire, Bedfordshire and Essex.

02Are your electricians qualified and registered?

Yes. Our electricians are fully qualified and work to BS 7671, including on every electrician fault-finding visit. Robinz Electrical is a NAPIT registered electrical repair service company, and our team holds City and Guilds qualifications. Every job is tested and backed by our satisfaction guarantee, and you can read our customer reviews.

03Do you offer emergency electrical call outs?

Yes. We offer 24/7 emergency call outs, seven days a week, for power loss, sparking sockets and other serious electrical issues. Our fast electrical fault finding makes your property safe first, then we complete a lasting repair. Call us straight away if you notice any safety concerns.

04How do I get a free quote?

Use the Get a Quote button or call our team. When reporting faults, tell us what you have noticed, and we will advise. Your free, no-obligation quote has no hidden costs, and our guide shows how much it costs to replace a fuse box.

05How long does it take to find an electrical problem?

Many problems are traced within a single visit. Our electricians test each circuit in turn, which can take from under an hour for a dead socket to several hours for a hidden wiring issue. We will give you a clear estimate once we understand the problem.

06Why are my lights flickering?

Flickering lights are often caused by a loose connection, a failing dimmer or an incompatible LED bulb. Occasionally they signal a wiring problem at the fitting or consumer unit, which can be a fire risk. If changing the bulb does not help, book a professional inspection.

07What should I do if a socket has stopped working?

Check whether the trip switch on your consumer unit has dropped, then reset it once. If the socket is still dead, or you notice scorch marks, heat or a burning smell, stop using it and call us. Do not open the socket yourself.

08How often should I have my electrics inspected?

Homeowners should have an EICR every ten years or when buying a property. Landlords need one at least every five years, and commercial premises are typically inspected every five years or sooner. Regular electrical inspection and testing finds hidden problems early, before they cause damage or danger.

09Do you work on commercial premises?

Yes. We look after shops, offices and other commercial premises, including installation, maintenance, testing and repairs. We plan visits around your opening hours where possible, so your business keeps trading while the work is completed safely. Out-of-hours appointments can often be arranged.

10Which areas do you cover?

We are based in Knebworth and cover Woolmer Green, Stevenage and the wider areas of Hertfordshire, Bedfordshire and Essex. If you are unsure whether we cover your postcode, send us a message, and we will confirm it for you straight away.
