What Our Commercial Clients Say:
Shashi Pal from Eco Tech Electrical Contractors Ltd was amazing. After being let down by a recommended electrician in London. I hastily contacted Eco Tech. They sent out an electrician the next day to do the EICR inspection and I received the report within 48 hours. In time for the tenant to move in as the previous certificate had expired. No EICR no moving in! Shashi Pal saved the day. Thank you so much.
Eco Tech worked so swiftly and their workmanship was absolutely immaculate! The engineer came to my flat on Sunday, installed an interlinked D1 LD2 alarm system for me and an emergency light and did a PAT test and a fire extinguisher inspection and within hours my FRA report was written up with all the compliance certificates attached for sn HMO. I felt so relieved and happy to be compliant and Ive honestly never experienced such prompt and professional service ever in the UK before! Thanks very much to Sashi and Eco Tec for a wonderful service at a very reasonable price. All the Best Therese
Excellent service. My ECIR failed and needed to provide the certificate tomorrow and the guy was very helpful in completing the work that needed to pass. Would highly recommend it.
I had been looking for a certified electrician to install a TT system, as advised by UK Power Networks. I posted the job on MyBuilder and Bark but unfortunately wasn’t having much luck finding someone with the right experience. The whole process became quite stressful, so I decided to ask ChatGPT for help. I was genuinely impressed with how it helped me find local electricians and identify professionals with experience in this type of work. It also recommended that I contact them directly first to explain exactly what I needed. I left a message and was relieved to hear back from someone who could actually carry out this type of installation. I specifically requested certification upon completion, and they had no hesitation in confirming that the appropriate certificate would be provided at the end of the job. I was also impressed with how quickly they responded. They came out the very next day to inspect the installation. The engineer explained all the available options, answered my questions and was very helpful and professional throughout. We agreed on a date for the work, and he turned up exactly as arranged. The job was completed neatly and tidily, even though the working space was quite restricted. It’s genuinely nice to find a reliable, professional electrician nearby who knows what they’re doing and takes pride in their work. I’m very happy with the service and would definitely recommend them to anyone looking for an electrician experienced with this type of work.
Fast turnaround, very polite and helpful engineer. I highly recommend this company.
I booked an EICR with Eco Tech Electrical Contractors Limited and was really impressed with the service. The electrician was professional, arrived on time, and completed the job efficiently. I received my certificate the same day, which was very convenient. Excellent service from start to finish — highly recommended!
I have very good experience with Eco Tech Electrical Contractors , I had emergency call out of boiler tripping issue and they fixed it quickly and price was very good ,they are Very punctual, professional and knowledgeable team , I will definitely use them again in future
I needed an EICR urgently and contacted Eco Tech. This was my first experience with the company and it was very good. They arranged an electrician for me on the same day, completed the testing quickly, and sent me the EICR certificate on the same day. Very professional and helpful service. I am very happy with their service and I would definitely recommend Eco Tech to others. Thank you 😊
I've tried contacting several electricians and most of them ignored me or the communication was poor. Eco tech was swift to respond and was quick to arrange an EICR appointment. Also their fees were the most reasonable. These guys are efficient. They get you booked in quickly, and give you the certificate within a few hours of the EICR test. They are NICEIC approved and their report was honest. I will use them again in the future!
The service was great and very professional. Engineer came to us and was able to complete the PAT in no time. Booking process was very smooth too and with just 24hr notice we were able to get our PAT certificate ready in time for our next event.

Explore Our Compliance Case Studies
Real-world inspections, upgrades, and risk assessments completed across London.
The alarm grade you need depends on your property type, risk level, and legal requirements.
For standard houses and flats, a Grade D1 (mains interlinked) system is usually required.
For HMOs, commercial buildings, restaurants, shops, and multi‑storey properties, councils normally require a Grade A fire alarm panel with L1 or L2 coverage.
If you’re unsure, we advice you to contact your local council.
For standard domestic properties and typical HMO layouts, we can usually provide a quote without visiting, as long as we have the basic property details.
For Grade A fire alarm panel installations, a site visit is normally required so we can confirm:
cable routes
panel location
detector/CP positions
access issues
material and labour calculations
We do not charge for the site visit itself. However, parking and congestion charges (if applicable) will be charged.
Yes — we install, test, and commission AOV (Automatic Opening Vent) smoke vent panels, including window actuators, control panels, fireman switches, and integration with existing fire alarm systems. AOV systems are normally required in HMOs, stairwells, commercial buildings, and properties with smoke shafts.
If you already know your council’s requirement, we can provide a quote based on the specification. For more complex systems, we may recommend a site visit to confirm actuator locations and cable routes.
After the installation is completed and full payment is received, we issue the appropriate NICEIC‑approved certificates based on the type of system installed:
Grade D / D1 Smoke & Heat Alarms You receive a Domestic Fire Alarm Certificate (BS 5839‑6) confirming the system meets LD2/LD3 requirements.
Grade A Fire Alarm Panel Systems You receive a Fire Alarm Installation Certificate (BS 5839‑1) along with system details, device list, and commissioning notes.
AOV / Smoke Vent Systems We provide an AOV Commissioning Certificate confirming correct operation, actuator testing, and panel setup.
All certificates are issued digitally and are fully accepted by local councils, building control, and HMO licensing teams.
