Keenan Electrical London Limited

Very happy with the work done by these guys. Got me set up with panels and battery and have seen the savings almost immediately. I'm happy to recommend their services.

Fast service

We had 11 Panels and a EcoFlow 10KW battery wall installed. We were doing renovations and Keenan Electrical were helpful and supportive to do the works alongside our main works. This meant we could have integrated panels on our areas of new roofing! Many thanks to Mark and the team!

After my enquiry, my appointment was arranged right away and I was told the technician would arrive at 8am. He arrived precisely at 8am. He completed his testing within 30 minutes and we agreed what should be done next. Mark Keenan called before 9am, we discussed my options, and the technician returned the same morning to fit the suitable thermostats. By 11am the work was completed. I highly recommend this company for their professionalism, quality work, and outstanding customer service.

Superb response time from Mark and Kieran did a great job.

October 2025 - I needed an external security light installing and some strip lighting with a loose connection fixing. Both done efficiently and well by Ali, who also gave me some helpful tips on electrical safety

Very professional service engineer who came to my home and fixed the problem value for money for the knowledge and expertise.

Great experience! The technician from Keenan electrical was very knowledgeable and super helpful. Great communication, great customer service. I highly recommend using their services.

I couldn't be happier with the service provided by Keenan Electrical and Solar. Mark and his team were outstanding from start to finish—professional, polite, and incredibly hardworking. They showed up on time every day, worked efficiently, and kept everything tidy throughout the project. What really stood out was their dedication. Rain or shine, they pushed through to make sure the job was completed on time and to a very high standard. The workmanship and attention to detail were excellent, and it’s clear they take real pride in what they do. I highly recommend Keenan Electrical and Solar to anyone looking for reliable, top-quality work with great customer service. Thanks again to Mark and the team for a job well done!

Five stars here because Mark and his team were quick, efficient and got the job done when they said that they would. The installation was on a house with some awkward architectural features - the walls are as hard as they come. Admittedly in a sunny period, the majority of my generation, 60% in fact, goes back to the grid, although the paperwork for payment is taking a while. A black mark for the scaffolders though - sub-contractors I believe. I have learned that scaffolders will treat your property as their storage yard, erecting and breaking down to suit themselves. The system that I have here appears to be pretty good. On a good day, I can iron, use the washing machine and oven (not all at once) seemingly drawing power directly from the sky. My morning cuppa, made before the sun is up properly, comes from what remains stored in the battery from the previous day. To be fair, this installation was done in late March in a nice spell. Writing this in late April. Roll on summer.

Absolutely exceptional service from start to finish. I previously contacted a local company which failed to call back. But Keenan electricals was swift, punctual and knowledgeable in installing my EV charger. Mark explained the whole process , did site visit(so I knew what to expect) placed the order and the team completed installation all within a week! I’m a happy customer and I definitely recommend them 100%

Very responsive in WhatsApp, Arrived early and did a quick fix.

Second time using Keenan (first for addition of outdoor armoured cable plugs, and second for a light fitting) and both times have had a great service. Prompt and professional, would recommend 👍🏻

Great job at a great price. Sorted the issue in quick time. Thanks guys.

Mark at Keenan have been exceent on our electrical work and very economical- theycwill always have our work- no job big or small is too much/ very friendly and efficient workers

Reliable and trustworthy. They worked quickly and at a very high standard and left everything tidy.

Very helpful and professional service. We had some LED lights fitted. Mark responded quickly and carried out the job really well. On a separate occasion, we called him as our fuse box kept tripping. Mark gave helpful advice over the phone which worked. No call out charge and no fee! Would definitely recommend!

Flexible with changes in plan! Great advice through the process of our home re-wiring. Always found solutions!

Mark did an amazing job for fitting an emergency light for us in our commercial property. I asked for something flush to meet our clinic room decor and he did exactly that. No damage, cleaned up and had no idea he was there. Thank you soo much.

Mark and his team are very polite,professional, fast and efficient .Quality for the price. Very highly recommended

Mark was brilliant. Personable, calm, diligent and great value. Throughly recommended.

Quick, friendly and effective - would certainly recommend

Mark came and fixed my lighting problem with no fuss and very quickly. Another electrician had come and said there was nothing he could do and the flat would need to be rewired, so I was very pleased when Keenan electrics solved the problem so easily

Mark called me back as soon as I contacted the company . He tried to resolve my problem on the phone to save time and money . Mark came out very quickly to our place sorted our RCD problem. I can’t praise Mark enough for his polite , professional and prompt service . I would not hesitate to recommend or use their services in the future .

We had a complicated issue with sub meters and multiple consumer units in our house that our Energy Supplier technicians couldn't work on and which Mark from Keenan understood and has simplified. He is very agreeable and was able to work with the day and time booking from the Scottish Power technician who was actually unqualified to do the work we required. Knowledgeable, reliable, excellent communicator and a good person. Very strongly recommend.

Keenan Electrical were extremely helpful, prompt, efficient and kind. The problem was sorted quickly and I recommend them very highly. I am so pleased to have found them and am very grateful to them.

Mark and his team responded quickly and professionally to our emergency problem. Diagnosed the problem and rectified it swiftly after being let down by our previous electrician who had not managed to diagnose the issue. Would definitely recommend.

Had a great experience with Mark and the team, when having an EV charger installed at my home. They were all professional and responsive and did a great job!

Absolutely brilliant service. I cannot recommend enough. I needed a pat test completed for work and keenan electrical were brilliant I was booked in for that same weekend and he came to me. Fantastic service very professional,polite and efficient. I will most definitely book again and recommend to everyone.

Mark did a great job and went the extra mile - would definitely recommend and book him again

Totally saved us in the middle of the night! We must have called a hundred so-called emergency electricians but kept getting ignored or hung up on. Keenan was so lovely and got our power back up and running in under 10 minutes. highly highly recommend !!!

Responded to my emergency quickly and effectively to my emergency. Completed the work in good time and efficiently. Made sure everything was fine before leaving. Very pleased with everything. vThanks

Reliable guys. Came over for a job after a call and his guys were super professional. Job was nicely done and place cleaned afterwards. Recommend them.

I used Keenan electrical London LTD for my Electrical inspection Amazing work Thanks Mark

I would strongly recommend using Keenan Electrical. We needed the fire alarm system tested on a commercial property and Mark was very responsive and professional. Nothing was too much trouble and the level of service was second to none. They are also reasonably priced in comparison to other companies out there. We would definitely use them again! Thank you Mark for all your hard work and for travelling from London to Royston to do the job. Much appreciated!

Mark and his team were very professional. They quoted a reasonable price, came when they said they would and did a good job. I would recommend

Very helpful and professional, good value, nice people

Keenan electrical at professional, attentive, and co-operative. I found them professional to deal with, fair, and did a very good job.

Mark talked me through the likely cause of the faulty bathroom power supply and attended the same day to replace the broken shaver socket. Excellent service - highly recommend the company for domestic electrical issues.

Great job, very quick and super professional. There was a complex problem that had confounded a previous electrician but Keenans found the issue rapidly and fixed the ceiling spots and get everything working. Very pleased and I recommend them highly.
