Highlights
“We have used Jamie’s services on 3 separate occasions for works inside and outside the house. Every time he’s proved to be reliable, courteous, efficient, helpful and with reasonable rates, we have always found that Jamie offers creative solutions and ideas which improve projects. We would have no hesitation in recommending Jamie and his team to anyone.”
“Jamie did a complete re-wire on our house and out to the garden. He was open and approachable and offered incredibly helpful suggestions that I appreciate now I am living in the house. His quote was very fair and he kept to the budget. He is very easy to work with (our builders gave him high praise). He is tidy and and works to a high standard. Would definitely recommend him (and have done so for family members) and am very pleased that we found him to do our electrical work.”

Competent, considerate and reliable. Would recommend very highly
Jamie did a complete re-wire on our house and out to the garden. He was open and approachable and offered incredibly helpful suggestions that I appreciate now I am living in the house. His quote was very fair and he kept to the budget. He is very easy to work with (our builders gave him high praise). He is tidy and and works to a high standard. Would definitely recommend him (and have done so for family members) and am very pleased that we found him to do our electrical work.
Excellent work
We had quite a lot of lighting work carried out by Jamie. He replaced all the ceiling lights in the kitchen , in a bathroom , in the garage and sorted out a timed light problem. I am really impressed, as all the work has been carried out to a very high standard. Jamie is very professional and punctual. His excellent work is also very neat and tidy. The invoice was exactly as quoted. I would not hesitate to recommend Jamie and would definitely use his company for any future electrical work.
Garden Electrics
First-time customers of O’Neill Electrical. Jamie responded promptly to our enquiry about troubleshooting our garden electrics problems. Jack made an initial assessment visit, clearly explained how he would tackle the tasks and shortly afterward returned to complete the re-configuring of lights and power sockets and re-programmed the wise box remote. We cannot fault any aspect of the job.

Excellent work
Jamie installed all the new cabling and electrical fittings for my kitchen renovation, and earthed my water mains. He and Adam worked quicky and efficiently, checking my requirements as they went. Jamie re-labelled my consumer unit fuses and wiring in my meter. It's lovely to have everything clear now. Detailed estimate and invoice as per estimate. A great job - I thoroughly recommend.
Speedy call out, reliable and trusted tradesman
I really highly recommend O’Neill electrical. Jamie was quick to get our call out in the diary, attending the morning of the next working day and was able to solve our electrical fault quickly, keeping us well informed of what needed doing and why. Great communicator and quick results. Excellent value for money. Thanks.
Endorsement Reference
Jamie installed extra lighting in our garden as what we had was not sufficient. He gave us advice on what fittings to use and did the works with minimal fuss and left our garden and patio area clean and tidy. I would definitely recommend Jamie to our friends and family.
Endorsement Reference
I had my fuseboard replaced after it had partially set on fire. Jamie was professional and proposed an electrical inspection prior to the fuseboard change to identify if there were any issues with the electrics that could of caused this. Overall really happy with the general communication, execution and quality of work provided

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
