N R T Building Services Group Ltd drew mixed reports from customers. Some reviewers were pleased with electrical work: one said the electrician was hard working and professional, another described Raul as punctual, thorough and knowledgeable and said he fitted a new socket neatly, a third praised Lee for being respectful and informative, and another said the work was excellent with no mess. Several reviewers reported missed appointments, including one who said nobody turned up or called, and another who said a second appointment was also missed and that the company later said no appointment had been made. One reviewer said the company kept phoning despite requests to use email because of work and a disability, and another said repeated requests for a Saturday appointment were not met. One reviewer said an unsatisfactory inspection was not reported to the relevant parties and that staff were rude and failed to provide a copy of the EICR, while another said electricians made false allegations and called social services.
I've had these guys out THREE OR FOUR TIMES already this year for electrical inspections on behalf of my housing association, and now I've had another phone call from them AGAIN. 🤦♀️ Surely an electrical inspection should be a one-off appointment, everything checked and signed off, and then that's it for another five years?! Obviously, I understand that if something needs repairing or there's a genuine safety concern, further visits might be necessary. But this has been going on since around start of this year, and it honestly feels like it will NEVER end! So, I get the phone call, and I explain that they've already been out several times this year. Their response? Apparently, the last person who came out never signed off the work and has since LEFT THE COMPANY. 😳 Excuse me?! So basically, I'm having to go through all of this AGAIN because someone apparently didn't do their job properly before leaving?! And somehow, I'm the one left dealing with all the inconvenience and stress. Absolutely brilliant. I honestly wish NRT would just do what they're supposed to do, get everything properly inspected, make sure any work is completed correctly, SIGN IT OFF, and leave me in peace! I've been dealing with this since the beginning of the year, and it's now October. MONTHS of appointments, phone calls, rearranging things and having to work around their visits. And knowing my luck, they'll come out this time and I'll end up with yet another appointment because something else hasn't been done properly. 😩 I completely understand that electrical safety inspections are important, and I'm not arguing against having them done. It's the repeated visits, the apparent lack of communication, and being left to deal with the consequences when things aren't properly signed off that's driving me absolutely mad! I am SO over it now!
Spoke to these people and made arrangements for a appointment i went out my way as she knows to make and ..... THEY DIDN'T SHOW UP NO CALL TO SAY NOT COMMING AS OF A HOUR LATER STILL NO CALL WILL NOT ALLIW TO WASTE MY TIME A 2ND TIME TYPICAL OF CENTRAL BEDS COUNCIL TO HIRE SUB PAR CONTRACTORS Hope they turn up for you and do not waste your time too Good luck 👍
Been told many times to email me for appointments but refuses to listen. Still calls me. I have explained written communication is best as I work and have a disability. It’s clear they need to learn what disability is and what respect is - because it’s evident they can’t follow simple requests from disabled people. It’s able and discriminatory
didnt turn up on day of the appointment, called a month later saying they need to book an appointment and i told them they didnt turn up to the last one so no and to not contact me again. they have since called me over and over again each time being told to not call me again. scummy company that harasses. EDIT. appointment booked for 27/05/26, they didn't turn up again and didn't notify they wouldn't be turning up, waited in all afternoon, they told me the next day they didn't turn up because there is asbestos and they're not able to do work with asbestos, that's fine but you should notify me of this, put in a missed appointment request through my landlord as I had to take time off to wait in all day, NRT responded to the request lying that there was never an appointment made with me, luckily I had the text with the appointment and I record all calls to untrustworthy businesses such as this.
Very pleased with the guy who worked on my electrical check very hard working and professional 8 Ashlar court Portsmouth 5/6/2026 Many thanks Belinda
Raul was absolutely fantastic! He came on time and carried out thr electrical testing with great efficiency, thoroughly and professionalism. He’s extremely knowledgeable, kind, and meticulous in his work. He went above and beyond by installing a new socket to replace one that wasn’t working. Everything was done neatly with no mess and to a very high standard. Raul is an incredible asset to NRT, and I wouldn’t hesitate to recommend him to anyone looking for a reliable, skilled, and courteous electrician.
Disgusting company. I have called around 6 times, saying I need a Saturday appointment as my husband is off work then and I work 6 - 7 days a week! I was told my property would be put on hold for work until a Saturday appointment came up! I have had 3 threatening letters, all saying I have made no contact and giving me appointments i cannot do! As a self-employed person who is extremely busy, I will now have to cancel clients with no space to rearrange them! Additionally, I am pregnant and the stress of all of this ended in me needing to attend the hospital due to severe cramping due to STRESS from this vile company! Absolutely disgusting! Avoid if you can!
I had an electrician visit today called Lee. He was very respectful of my home, informative and genuinely kind. Not many tradesman take such care these days. Very grateful for his time and professionalism. Even my cat liked him! Thank you 🙂
ELECTRICIANS FROM THIS COMPANY MADE UP FALSE ALLEGATIONS ABOUT MY HOME. LIED AND CALLED SOCIAL SERVICES. BE VERY CAREFUL WHO YOU LET INTO YOUR HOME
Terrible company. Letter containing nothing but bullied contents saying can force entry to homes just to get job done when thay only work for housing associations. Think above the law well think again nrt you arent .
Excellent work, plus helpful and polite Left no mess, put everything back,I could not fault them
If I could give 0 stars, I would. Avoid use of this contractor at all costs. They will compromise your safety and well-being. The electrician reported an unsatisfactory inspection, however the contractor failed to contact the relevant parties to notify them of this outcome to carry out urgent remedial works . The administrative staff are incompetent, rude, defensive and lack the knowledge to deal with valid customer concerns regarding electrical safety. They failed to provide a copy of the EICR, disconnected phone calls when I expressed genuine concerns about my safety and failed to escalate customer complaints about their negligence.
Great company and staff
