Dan came out promptly and carried out the work needed efficiently and tidily. Was very friendly and didn’t try to sell us anything we didn’t need. He also didn’t try to blind us with science and explained everything clearly. Will use again and am happy to recommend to others.

Excellent service from start to finish. Dan was a pleasure to deal with, explained things really well and the job was done to a really high standard. The job was to fit 30 CCTV cameras on a big building to cover both inside and out. I was kept updated throughout the process and the quality of the equipment and his work was brilliant. Very honest person, punctual and always cleaned up after him. Would highly recommend.

September 2022

Great service very reliable. Very friendly. Highly recommended this company.


I have used Dan on a number of occasions from cctv and an alarm to security lights. I used Dan recently to do all my electrics after a new kitchen installation. He done a great job and was very patient when he had to keep coming back between other trades. Nice friendly lad who will always look after you and do the job properly, safely and in a timely manner.


Dan arrived on time, all work carried out and tested as required. All areas cleaned up after work completed. Very pleased with Dan’s work and very competitive price. Would highly recommend getting a quote.


This is the second time Dan has carried out work for us, this time in our new build. Fitted interior lighting to a very high standard at a great price. Always extremely friendly and takes great care tidying up. Some of the lights took a lot of assembly but it wasn’t a problem.


On time, very efficient and knows his alarms. Very happy.


A job well done. Would highly recommend. Dan came when he said he would and followed up with a quick quote. He kept us up to date via email. He explained what we could have and offered suggestions. On the day of fitting he was very respectful, wearing a mask and overshoes in the house. He cleared up after him and left everything as he had found it. He fully explained the system and showed us how to use it and also talked us through downloading the App and how to use the App. Many Thanks Dan


Can not recommend Dan enough. He did a superb job of installing two cameras to the front and rear of my property. His work is so neat.(cabling) He arrived on time explained the options, consulted with us every step of the way. He cleaned up on completion. Explain how the system worked and gave the reassurance he would return if we were not sure of anything. Nothing was too much trouble for him. He even spotted a wasp nest in our brick work that we were unaware of. Price was very very reasonable. Guarantee was included A lovely polite courteous young man. His work is 100%. Well recommended.


The work was carried out to a high standard, Dan was helpful and cheerful throughout the fitting, I can not recommend him highly enough.


From start to finish my experience with Dan has been nothing but positive. He provided a reasonably priced quote for the supply and install of the alarm system and arrived on time to complete the work. Dan was extremely professional throughout the installation which was completed to a high standard. Would recommend Dan to anyone.


Excellent service, Daniel repaired my house alarm after carpet fitters had cut through the wires. Extremely happy with the work carried out and would highly recommend him.


Excellent friendly genuine service. Helpful explanation on the use of the alarm. Highly recommend


An extremely professional engineer who is courteous, reliable and a credit to his profession


Excellent service provided today by Dan who installed cctv cameras and accompanying monitor at my home. Dan has been very professional and responsive throughout from initial contact/quote to the actual work carried out. Really happy with the work carried out and wouldn’t hesitate to recommend this company.


We have used Daniel before so when our daughter needed an alarm we called Daniel in again. He responsed quickly and once again did a reliable and neat job at a competitive price in a professional and friendly manner. Would highly recommend.


Dan installed our CCTV whilst we had scaffolding up and was insistent that we reviewed the positioning when the scaffolding came down. True to his word we needed to move it slightly and the work was carried out perfectly this am. Brilliant service!


Houghton le Spring

After a year of total nightmare with tradespeople (a garage conversion from a Sunderland company) Dan came to put stuff right and install some new parts to an existing system. What a breath of fresh air! Dan was on time, polite, efficient, cleaned up after his work, and reasonably priced. He then came back to do an additional bit of programming for me and didn’t charge. Thank you and I’m happy to recommend you, Dan!


Knowledgeable about the system, able to test and fault find to a high standard to fix the fault. 10/10. Highly recommended


Whitley Bay

I really thought the system was too old to repair but Dan knew exactly what was needed and fixed it. He was very pleasant, thorough and had the whole system up and running again in no time. Very pleased with the outcome.



Excellent job. So professional and explained everything fully



I would like to say thank you to Dan for installing the CCTVs and showing me how to use the app. Dan was very polite and thoroughly explained and took his time to answer any questions I had. He gave me a quote and stuck to it. He was very tidy and installed everything neatly. He went out of his way to check an old burglar alarm system for me. I’m very happy with the service I received and I will definitely recommend him.



Mr Clark came out and inspected job within 24 hours, explained what problem was and how it should be remedied and provided a quote and then came out the next day and carried out work – everything was done very efficiently and professionally and I would not hesitate to use him again in future or recommend him


Houghton Le Spring

Very polite down to earth person. Easy to talk to and ask advice and he made sure I knew the work.And how it worked. Reliable and tidy. Would highly recommend.


Houghton Le Spring

Dan came highly recommended and did not disappoint. He was very informative and explained everything in detail and advised us on how the CCTV would be installed and the type of cameras that would be used. Dan came out the time and date arranged and was very professional and very tidy in his work. When everything was installed and the app successfully downloaded onto our devices he took the time to run through the operation ensuring our understanding. Excellent service would highly recommend Dan.



Dan was professional throughout and kept us informed about the work he was carrying out all through the day, couldn’t fault him. He was courteous, professional and tidy, would highly recommend



A fantastic job from Dan. I had called another installer, had them out then never heard back despite two chases. Dan came out the day I called up and provided a written quotation that evening. He emailed me to confirm a start date for the job and arrived exactly on time taking time to discuss the agreed work again before starting to ensure it was still what I wanted. The work was carried out perfectly, with real attention to detail, and tidied up afterward. We are very pleased with our alarm and CCTV and wouldn’t hesitate in recommending Dan to anyone, he’s got a cracking work…


Houghton Le Spring

Dan fixed our alarm within minutes and wouldn’t charge, I would recommend him to anyone.


Houghton villas

Only took a few hours as Daniel works alone was kept informed all the way through the work very friendly man down to earth good sence of humer



Arrived on time, worked outside in horrible weather with no qualms, job was completed on time and a very tidy install too. Definitely recommend


Chester le Street

This service was brilliant from start to finish. This job was completed to a high standard and in a timely fashion. His expertise and knowledge allowed us to choose a package that was suitable to our needs. Would definitely recommend Daniel to others.



Brilliant service. Fast efficient and would definitely recommend



Highly recommend would use again. Very professional an excellent job done as requested


Houghton le Spring

Asked to come out fix house alarm after wires had been cut due to new door fitting. Dan was very skilled and professional throughout. We later found out that the sounder had gone and we needed a new one and he came back to fit this also. Highly recommend would use again if needed very tidy and polite



Daniel displayed great competence in system analysis and kept us informed of all issues. Prompt response, well organised, tidy and helpful. No need to go anywhere else for this type of work.


Houghton le Spring

I had a few quotes to fit cctv recently and we decided on Dan to do it judging him purely on instinct when he came to do the quote. Dan took his time and went the extra mile making sure the wiring was recessed behind the wall cavity which is what we wanted. Dan was polite and friendly and didn’t rush the work or start stressing like a lot of tradesmen do these days. We have already booked Dan in to do a house alarm and would not hesitate in recommending him.

Another 1st class piece of work whilst carrying out Annual alarm service Extremely competent at his profession and would have no hesitation in commending Dan to others Thank you

Sunderland Mar-20

Prompt, pleasant and efficient.

Washington Mar-20

Dan is a polite and friendly guy who after our recent burglary made a real effort to get us sorted for CCTV, alarm and security lighting. Despite having a busy week he worked the weekend so we could have some peace of mind. His quotes are reasonable and he will even try to dissuade you from getting what you don’t need. The work was excellent and he cleaned up after himself. His aftercare is second to none also. Definitely recommended

Houghton Le Spring Feb-20

Dan arrived on time and fitted a new alarm system and security light as requested. Work done to a very high standard and Dan took time to explain how to operate the new alarm making sure everything was working before leaving. Would definitely recommend and not hesitate to use Dan again for any future work.

Gateshead Jan-20

We agreed the work to be done during his first visit. Dan arrived on time and set to work. He is an efficient, industrious worker who applied himself fully to complete the job on time. He provided updates on progress and completed the cctv installation within the time allotted. He then checked the alarm and replaced an old battery. He declared the alarm totally functional after the change. It works smoothly now. He provided advice about how to get the best from the new system. He offered a contact phone number should we require further information in future. All in all an excellent service.

Dan did a great job from his first visit to quote through to the briefing. He is a bit slow answering texts and emails…. but he’s a busy man! Kept to his word about dates and timings and fitted a system that, compared to other quotes, was of higher specification for approx the same cost. Already planning to give him more work.
