Great Service. Richard and young apprentice arrived on time assessed the issue and quickly concluded that the issue was caused by old lights which were faulty. They replaced with new lights and tidied up all the cabling. They were polite and very clean. Would recommend them and use their services again.

Reliable, Professional & Goes the Extra Mile I can’t recommend Tony and his team highly enough. From start to finish, they were professional, dedicated, and incredibly hardworking. We had a tricky electrical issue, but they didn’t give up—they methodically worked through the problem with real determination until the end. On top of that, they installed our new oven perfectly, making sure everything was safe. What really stood out was their attention to detail and willingness to go the extra mile to get things right rather than rushing the job. If you’re looking for reliable electricians these are the people to call.

Domestic electrical works I found the electrician very polite and courteous (including wearing protective shoe coverings whilst in the house). He was late arriving however managed my expectations by contacting me in advance to let me know. Work to replace a spur and outside security light were completed with the minimum of fuss and electrician cleaned up after himself. I asked him about another job (which I had not previously mentioned) but this could not be completed (needed parts) however he advised what needs to happen to sort it, which will require another visit. I recommend their services.

Excellent service, even if only to change a faulty light bulb! Arrived within a couple of hours. Very friendly. I hope they laughed as much as I did at my stupidity using dodgy bulbs and thinking it was a more serious problem. I blame old age! Thank you.

I am so happy with the work done for me by this company. Even though the work I needed done was quite small, the engineer sent was very pleasant, polite and professional. He replaced the batteries in my smoke alarms and replaced the light pendant in one of the bedrooms with ease. He took time to answer questions I had, cleaned up the little mess left while removing the light pendant and checked that everything was in good working order before he left. I think I have found my go to company for dealing with any electrical issues I may have in the future. I am very happy to recommend this company to anyone wanting good service for a reasonable price.

I have just used ths for my mum, to rewire her lighting circuit and new fuse box. Tony and his guys were absolutely brilliant, they've done an outstanding job, my mum is over the moon. But more importantly they were very respectful and helpful towards her as she's not in the best of health. I would 100% recommend very well priced and lovely fellas to boot. I would give more stars if I could.

I called THS Electrical Services to ask if they were free the following day to replace a faulty light switch and replace a broken outside light. Richard Ha asked me to provide a photo of the broken light which I did by email and he responded by return email with a price which I agreed. He arrived at the appointed time and thoughtfully applied plastic shoe covers before coming into the house. He fixed and tested the faulty light switch quickly. Replacing the broken light with the new PIR version I had purchased took a little longer as it was a bright sunny day and mimicking the dark and movement required for the PIR to work was tricky but Richard persevered and got it working to my satisfaction. I was extremely impressed with Richard's clear and prompt communications skills and his professional approach. He even sent a text next morning to check the light was working OK, which it was. I highly recommend this company and Richard in particular.

How Long Does Your Home Wiring Last?

Electrical Wiring has a lifespan no matter how long it may be. If your home has a quality wiring (with copper wires), your wiring will last longer than that of an inferior quality like the aluminium wires from ages ago. What is the electrical wire lifespan? Electrical wiring may last about 50-70 years depending on the quality of work that was carried out by the electricians.

Even though the wiring in your property may last this number of years, don’t rule out the fact that it can be shortened if the quality of work is poor. Book a professional today for a complete or partial electrical wiring.

Complete rewiring FAQs

  1. If you are getting a house extension or converting one or more of the rooms, for example getting a roof conversion or converting a garage into a new room, you will need to have an electrician check that the electrical work meets the current standards.
  2. If your current home electrics have not been upgraded in the last 25 years then they will need to be checked out to ensure they meet current standards and regulations.
  3. If it is over 25 years old it is highly likely that you will have to at the very least, need a part rewire. Electrical safety will need to be checked and improved to make sure it can carry current loads, it is earthed properly to meet current standards and that cross bonding satisfactory.

There are several signs that indicate your property might need rewiring. These include frequently blown fuses or circuit breakers, flickering lights, charred outlets, burning smells, or outdated electrical systems with cloth-covered wiring. If you are unsure, it's best to consult a qualified electrician for a thorough inspection.

The duration of an electrical rewiring project depends on the size of the property, its current wiring condition, and any additional electrical upgrades required. We work with minimal disruption to your day and try to work as swiftly and as possible, ensuring it is done safely and efficiently.

In most cases, you can remain in your property during the rewiring project. However, there might be certain instances where temporary relocation is necessary, particularly if extensive work is required or if your property's safety is compromised during the process. At THS Electrical, we make sure that our electricians guide you on the best course of action.
