Krzysztof did a great job fitting 2 showers, decorating ensuite, changing all the taps and 2 showers, and doing a number of small fixes and improvements in the flat. I appreciate his clear and detailed communication on job needed, options provided, and consulting on fittings and materials. He finished the job with high quality and with just a small delay despite of a good amount of obstacles (we did painting in parallel). Would definitely recommend Chris's services!

Dorian from Bello Electric accepted my enquiry and arrived very quickly. He commenced tracing the fault immediately and carried out his investigation with obvious skill and knowledge. Speedily eliminating a number of possibilities he established that the fault lay with external wiring which appeared to have been damaged by rodents. Repaired. Left site tidy. Really pleased. I'd give 6 stars and very highly recommend. 512 characters is not enough to adequately say how good he is.

Simply great, came round took notes, went through all we wanted, gave quote including materials, required 50% up front rest on completion, turn up as agreed, said it would take a week but done in 4 days! We added a few minor things as we remembered them but no hassle, added them in. Very happy with results.

Professional, quality work,worth money

My name it’s Cris. I am a person with many qualities in handyman.What a handyman means? A handyman, also known as a handyperson or handyworker, is a person skilled at a wide range of repairs, typically around the home. These tasks include trade skills, repair work, maintenance work, are both interior and exterior, and are sometimes described as "side work", "odd jobs" or "fix-up tasks". For me a handyman means the person who helps the people who are in need or not having the necessary training for that thing and at the same time the one who later gives a smile to the people's face. For this, please contact me in any need you have
