Completion of landlord remedial electrical works

As a landlord I need to ensure that my property is electrically safe for my tenants. It's 5-year insepection highlighted the need for some remedial work to replace one kitchen power ring and replace one RCD. Alan is prompt, efficient and knows the electrical regulations. He handled my tenant well, completed the work properly and then provided me with the electrical test certificates that I need as a landlord to prove electrical system is safe. Thanks Alan to you and your team for dealing with this remedial work quickly and efficiently.

Would definitely recommend

AAB Electrical did a fairly big job for us that included a new consumer unit, rewiring and EICR, and we were very happy. Communication was great. Alan responded to emails quickly, took the time to explain things clearly and gave us options. He was professional, kind and helpful both with us and with our tenant. Alan put together a big team to finish the job in one day. He helped moving things before the works and left the flat clean. The installation looks tidy and the damage to the plaster and décor was minimal. We received all the paperwork soon after completion. After the job was done there was a small issue (that later turned out to be with an appliance). I called Alan and he attended the morning day after to check what it was. We would have no hesitation to recommend AAB.

Excellent Installation of New Boiler and Consumer Unit

Alan and his team drained and removed my old boiler, supplied and fitted a new unit, replaced our fuseboard, fixed half a dozen problems with down lights and smoke detectors and performed an EICR. Everything was done in one day and they left the flat spotless. Alan stands out for me as he explains everything with incredible patience and throughness, so you know exactly what they are going to do, and what it will cost. He also is good at giving options for how her tackles things. His team were great. Would definitely recommend.

Professional, knowledgeable and Friendly team.

Alan and the team were great. Had a problem with our electrics another contractor couldn’t solve. Alan reviewed the issue and resolved it in the most cost-effective way with minimal disruption. Lovely team, professional, polite and fun. Will use again.

Great service as usual

AAB identified my specific heating problem, discussed all the remedial options and we've made a long-term central-heating plan for the whole flat all within a one-hour visit. Very good professional value.

Good service and delivered what they promised.

Arranged an EICR inspection on a few days' notice, electrician turned up on time, did the job and delivered the report the next day (even though that was a Sunday). While on site the engineer was polite, talked me through what they found and what follow-on work might need doing. They answered the phone and responded to emails promptly. Would definitely use them again.

Fix hot water issue

I called out AAB Electrical & Plumbing Contractors Ltd to fix a hot water issue in my electrical boiler. On arrival the engineer diagnosed the issue to be related to immersion stat faulty not only for hot water but also for central heating. Firstly I found it strange that both of the stats had gone faulty. I agreed for these to be changed and the engineer replaced the stats. I received an invoice from the engineer's company AAB Electrical & Plumbing Contractors Ltd for total of £438.62 and the engineer demanded immediate payment. I sent a message to the engineer asking for the faulty parts to be left on site as this was requested by the insurance company to which the engineer got aggressive and very angry and told me that he has thrown it in the bin. So I asked him which bin he said he doesn't know. The engineer was more interested in getting his invoice paid than he was in helping me with my issue. He also charged 2 hours at £115 per hour whilst he was only on-site for less than 45 minutes. My tenant noted down the time engineer arrived to when the engineer left. I was very surprised he had charged for an additional hour and I then suspected he might not have even replaced both stats as he did not want to leave the faulty parts behind. After the engineer left thinking the job was complete, within a few hours the central heating packed up and I asked the engineer if he had tested everything before he left and he said he did, this again is not true he couldn't have done as it stopped working shortly.

Small plumbing job

The problem was a tap on the shower which we were unable to turn on. Having tried several plumbers who were either not interested or couldn't commit to a definite day I called AAB Plumbing. I spoke to Alan and explained the problem, he asked various questions and asked me to send him a picture of the tap. He also explained fully what their charges would be if we decided to go ahead. Once he had received the picture of the tap assembly he rang me back and we agreed a date and a time (between seven and seven thirty AM). The plumber arrived bang on seven. He replaced the tap and was gone by seven twenty five. As agreed I paid the plumber by credit card and he prepared an invoice and emailed it directly to me. Both Alan and the plumber (sorry I can't remember his name) were very professional and easy to work with. From past experience I know it can be difficult to find a plumber who will do small jobs like this one.

Great communication and great service

I found AAB Electrical services through Which trusted trader and I'm very glad I did. Hence I wish to add to their five star reviews with my own review. I asked AAB to quote for a new electric board I required to be able to obtain an EICR certificate for a flat I let. Alan was super efficient in replying to my request. To keep the inconvenience to the tenant to a minimum Alan was able to give me a rough idea of what I may need by looking at photo's sent by my tenant. Once I agreed in principle to the work required an electrician was able to visit the property. They changed the board and checked all the electrics on that visit. When the electrician had finished her work at my property she called me to talk me through everything that had been done and even offered further advice. For instance she thought it may be worth thinking of switching to more efficient kitchen lights in the future. It seems like such a small detail but how many other trades would call after they've visited your property, on a Saturday because that was most convenient for my tenant, to talk you through how it went and what they'd done. I can say for sure it's never happened to me before. Great service. Changing a board is a big cost but I am very happy with the service and work provided by Alan and his team. I wouldn't hesitate to use them again. Thank you for the great job AAB electrical.

One of the best tradespeople I have ever used

Highly impressed by Lal at AAB. She contacted us within an hour of getting in touch; was switched on; asked great questions; came on time; came within days of first query; cleared up; did not break anything; was pleasant and easy to deal with. I could not recommend her more.

EICR remediation work: replace fuse box and lighting

Alan and team did an excellent job, assessing the electrics for EICR purposes and then addressing the work required. Alan and team were punctual, honest, trustworthy and really cared about doing a good job. Their advice was detailed, they paid great attention to detail and kept me me well informed at all stages of the work. I would wholeheartedly recommend the team at AAB.

top quality service

faulty light fitting replacing - AAB came within 48 hours - ok perhaps it was a lot to replace one light fitting but a) I am not an electrician b) I prefer not to risk electrocuting myself and c) they had to come into the congestion charge zone - so money well spent I feel ! They arrived absolutely when they said they would, and the job was completed intelligently, quickly and efficiently. Also had an opportunity to ask for advice on possibly replacing the fuse board - but that's for another day

Top Quality Work

Alan has done at least 20 jobs for me over about a five year period. His knowledge in the electrical and plumbing fields is superb. His work is done to the highest standard. His response time is also very quick. Even for non-emergencies he often makes time to at least make an initial visit within 24 hours. He always explains very thoroughly what the problem is and how it can be fixed. I have no hesitation at all in recommending him very strongly.
