Highly Recommend Joel
Joel is the go to electrician at my cafe and couldn't recommend him more highly. He's always reliable, punctual, and a pleasure to work with. He turns up when he says he will, explains everything clearly, and takes real pride in the quality of his work. Nothing is ever too much trouble, and he always leaves the job tidy and completed to a high standard. He's friendly, professional, and someone we completely trust to work in our busy café environment. It's a real pleasure finding tradespeople like this. Highly recommended – we'll definitely continue using him for future work.

Top man, top service.
Joel was prompt, clear, helpful and frankly just quite impressive. I got a strong sense of value for money to match his expertise.

New Fan and lights Fitted
It's been a real relief to find Joel. Whenever I need a bit of electrical work I can give him a call and I know the price will be fair and the work will be done well. This time he fitted an extractor fan for my kitchen and some new lights to light my work surfaces. Great job, all left neat and tidy at the end. High recommend.

Great friendly service
Joel was recommended by a neighbour and offered a great service. He was easy to reach and did a thorough check over the phone to see if we could avoid a call out. He found the problem with our lights and fixed it quickly, making sure that we have the best value option available as a solution. I would absolutely recommend to anyone else looking.

Unreservedly recommend
I have used Joel a couple of times before so went straight to him when I needed a double socket added to my new place. He responded quickly, and even though its a relatively small job he was happy to help, giving his advice on what would work best for us. He fitted the plug and left the place clean and tidy as always. Thoroughly reliable and trustworthy. Whenever I have any electrical work needed, I will always use Joel for peace of mind and full confidence in his work.

Replace external security light
I have used Joel several times for various different jobs. He is always on time, communicative, efficient and professional. On top of that he's a very friendly, nice guy and clearly explains what he's going to do and why, including any potential issues he may encounter, so that you have a good understanding of the situation. I think he's very reasonably and fairly priced too. Most importantly of all, he does a great job, first time. I shall be using him again and thoroughly recommend him.

Fault fixed with no fuss
Joel made a return visit to us, having previously replaced all our light fittings with LED units, which he made a great job of. There was an issue with a faulty dimmer switch, which he repaired very quickly. As before, good and prompt communication, friendly and efficient service, excellent value. We would not hesitate to use Switch Green again.

Great work!
Joel relocated a light, put new heavy lights in and sorted out a faulty switch. He took a lot of care over the work and was super knowledgeable and friendly. Further to completion I had a clear invoice in line with the original quote and a separate NICEIC installation certificate from NICEIC via email for my records. Very professional, trustworthy, would recommend anytime.

We have electricity!
We initially asked Joel to connect our garden room to the house’s electrical supply. We were pleased enough with the service that we also hired him to install a bathroom extractor, doorbell, and 1st and 2nd fix on our kitchen. I particularly liked that the quotes given were clear, and we always knew which materials were included. Communication and scheduling was done very well too. It was also appreciated that Joel would point out any opportunities to reuse materials, so as to minimise waste. I don’t have any hesitation recommending Joel.

Another great job and at a reasonable price
Joel replaced 3 malfunctioning pull cord light switches for me at a reasonable price. Arrived when he said he would and did the job in next to no time. I would welcome Joel back any day.

Excellent electrician and a pleasure to have in the house
Joel was brilliant. He replaced the lights under our kitchen cabinets and fitted our new oven. He gave us excellent advice on the kind of lights to fit. Fitting the oven was more complicated than it should have been because the previous oven had been fitted without a backplate. Joel had the necessary parts in his van and had the oven fitted and tested quickly and smoothly. Joel took away the oven and cabling to be recycled. He worked very efficiently, and his prices are very reasonable. A pleasure to do business with.

Light fittings & switches
Excellent electrician — installed a new light, hung three lighting pendants, and fitted several switches. The work was carried out to a high standard, communication was clear, and everything was left clean and tidy. Highly recommended.

The Best, and GREEN with it
Being a contortionist he managed to move new fireproof fuse-box the necessary couple of feet to the outside of the cupboard, which I think contributed a great deal to the reasonableness of his quote,saving him time & me cost of ducting & wiring to what wd have been only alternative position 12 ft away. I would like to give him 6 stars rather than 5 as 2 of the rooms he had test the sockets in where decidedly unpleasant – I cdn'r even go in them! Because my husband had been 999'd to hospital I was unable to keep to the terms of the of the contract which asked that access to all sockets was available & that we are responsible for replacing any furniture that had had to be moved. Joel just went ahead & did this. Had been suffering from plague of mice & using silicon Joel blocked some holes left by Sparks our vendor had used. Kitchen ceiling lights needed replacing - had been told by 2 Sparks that as they were in a slanting roof , the ceiling would need replacing. Joel confirmed that it would save elec.costs if changed to LED - he cd do from his ladder by simply unscrewing present light & replacing with LED after fiddling with some short wires for eac Joel's a kind caring honest bloke who is good at his job and cares about people, living up to his working name SWITCH GREEN by taking all the bits of wiring left over from his work from me & that I had collected. Normally I loathe having workmen in the house but Joel I look forward to seeing!!!

Outstanding
Joel carried an EICR, undertook remedial work that included installing a new consumer unit, and carried out a range of other electrical tasks. He provided a detailed schedule of work in advance, which I really appreciated, and everything was completed to schedule and to the agreed budget. He was very professional, offered advice, explained what he would need to do at each step, and took care to minimise damage to any floor boards that needed to be lifted. I highly recommend him.

Highly recommended electrician
We had Joel replace some electric panel radiators as well as some smaller electrical repair works around our apartment. Joel was helpful, responsive and forthcoming with advice and recommendations as part of scoping the works and putting together a quote. He worked quickly, efficiently and tidily around the apartment, and was clear in explaining what he was doing before starting any task. He completed the works within the time he had allocated and left behind no mess. The job was exactly as quoted. Joel was friendly and approachable with any queries throughout the process end-to-end. I'll be using Switch Green Electrical again and highly recommend their services for electrical works.

Great work
This was Joel’s second visit to our house. He was trying to identify why our lights were ‘tripping’ which is no mean feat as it is a large house. He went through the place with the meticulousness of a detective and eventually found the culprit. Despite being here for ages, I received a very reasonable invoice. Plus he went to the task I a good humoured way, despite the challenge. Would definitely recommend
