Cannot rate this company highly enough; they were brilliant. The quality of the work was great; they took pride in what they did. They came and quoted, and provided a clear statement of work on what we agreed. They completed the work quickly. Turned up when they said they would, and if they couldn't, they let me know. Really good communication. They were so polite, courteous, and just generally really nice people to have in your house.
This is the last Gas, Heating and Plumbing company that you will ever acquire. I, Lewis Willoughby personally undertake all site visits and complete projects to the highest possible standard, always putting my clients first.
Lewis was very professional and efficient. Couldn’t wish for better service all around. Happy to use him for any future jobs and would highly recommend him to any body looking for a 5 star service.
My name is Akos, I am originally an architect but I have a company called Zebra Services here in the South of England including South London. I do a lot of things by trade but my favourite occupation and our specialty is roofing, guttering, chimney and decorating, and painting, this includes minor plasterboard work, doors, skirting boards etc. But I wouldd rather have them talk about what others think of us: Akos and his colleague that worked on our house were thorough professionals and took great pride in the work they do. Honest, on time, and always thinking on their customers' behalf. He will be my first call if I have anything else that needs looking into around the house. Ahmed, Putney The work was done thoroughly and within the agreed time. Very polite people, no hanging around on phone calls, cleaning up after the job. A pleasure to have Zebra around. Will definitely use them again when necessary. Christian, East Grinstead Akos did a good job on my summer house. Plus he was punctual, pleasant, hardworking, quick and sensibly priced. What more could one want? Would happily recommend him. Alice, BN7 Akos was excellent from start to finish. He is a perfectionist and a very hard worker. He worked through the rain to complete the job on time. He did excellent repair work on a highly damaged chimney stack and repaired gutters. Would definitely use him again. High-quality work and is a very pleasant man. Christopher, TN21 Akos did an excellent job in very unpleasant conditions and I couldn’t be more pleased with the result. Definitely intend to use Zebra again. Keith, East Grinstead Akos was charming and diligent. His initial inspection was detailed and his subsequent work was quick and neat. I will be using him again Martin, Brighton Akos fixed everything for us. He is an excellent tradesman. Highly recommended. Timothy, RH19 Absolutely brilliant job. Really good fair honest guy and very good workmanship. Will definitely use him again for anything roof/gutter related and would recommend him. James, KT6 Thanks for carrying out such good work in my flat at a reasonable rate. I will definitely have you back again and recommend you to friends and family that are looking to have work done. Thanks again. Clyde, Dartford Akos proved to be a hugely competent craftsman who completed our roof and guttering repair on time and within a reasonable budget. We have no hesitation whatsoever in recommending him. Phil, Forest Row
Very efficient and courteous worked Respectful of our property and cleaned up on completion of the work done.

Poor contact, I was doing all the chasing. Flooring cut short in places, new shower fitted leaking. Jack advised date to fit bath panel and towel rail then cancelled. Has worked out very expensive because I have paid for a heated towel rail and bath panel that has not been supplied or fitted. When job was agreed in June, Jack said he was fully booked for 2 weeks, now August and no sign of completion and no contact from him. Would I recommend Bathly Plumbers? NEVER
