Greg Ford
Highly recommend 3hcctv, Andy and James installed my old system 10+ years ago and it was time to upgrade, called the team and they came out quickly and talked me through all options, a week later full up to date system all installed, all working perfectly. Great service from start to finish.

3H Security provided me a high specification 4K CCTV system covering my whole house. I was really specific that I did not want any cables showing around the exterior brickwork and 3H could not be more accommodating! Nothing was an issue. They worked efficiently and left everything spotless.
Daniel
Absolute legends. Andy and the lads just finished a complex 3-day install of our new camera system in Holymoorside. Professional, tidy, knowledgeable and genuinely nice guys. Would not hesitate to recommend to anyone looking for CCTV or electrical work.

Brill service, fitted us in on a Sunday, nice neat job n decent lads, polite and tidy. Can't fault them at all. Will definitely use again for any security or electrical work we need in the future.
Leanne Stevens
Neat work, arrived on time, tidied up after themselves and were helpful and polite. The new outdoor up and down lights look great. I had originally asked for 4 cameras but they were honest and advised me that 3 cameras would cover the areas I needed. Really appreciated the honesty.
Thanks for your kind review Leanne and were glad you're happy with your new lighting/security systems. Kind Regards

Andy did a fantastic job at fitting six CCTV cameras on my property and installing electricity to my stables. He fitted an internal strip light and two external floodlights, one with a motion sensor. There was no mess with him and James working and they were very polite and professional.
