Boiler refit with associated underfloor heating work and further bathroom installation.
10Verified Review
As am a picky, difficult yet not impolite customer, I don't usually provide reviews. Tradesman don't usually like me and vice versa. Aziz and his team however are a rare breed indeed. Working tirelessly with unswerving dedication, they are committed to executing work to a high standard, but equally prepared to explain the process throughout with attention to millimetre type detail if called to do so. The team consistently demonstrate an extremely positive can-do attitude, so often lacking with other engineers and fitters. Got the job done properly in uncompromised fashion. Simple as that.

Emergency call
10Verified Review
I called for an emergency as boiler and heating not functioning. Aziz managed to fit me in within hours of the call and did a very good job. It was quoted and the job was clean and precise, they recommended further intervention once on site and quoted for it. So all was done quickly and efficiently. All documented with pictures too (I was the landlord and not present.) I would recommend any time.

Full house renovation
10Verified Review
Aziz and his team gutted and completely redid our mid-terrace house in London. The job was quite a complex one involving extensive building work, plumbing, and a complete electrical rewiring. The works were finished to high specifications and with only minor issues and delay. Aziz and his team are perfectionists and capable of carrying out work to a standard above that of many other London builders. I would not hesitate to call upon Certified Group again or to recommend them to others. The team and subcontractors was friendly and polite with neighbors, etc.

Plumbing and flooring
10Verified Review
Aziz and his team (Karim and Chris) carried out a number of jobs on my rental flat in Lewisham: fixed and serviced boiler, balanced central heating system, installed washing machine, fixed the toilet cistern and replaced the kitchen floor. Reliable, punctual, polite and stuck to the agreed schedule (important when there are tenants in situ). They were a pleasure to work with. Aziz kept me informed and updated, and also explained very precisely what they were doing and why, which really helped my peace of mind. I have absolutely no hesitation recommending them. Top blokes. Top job. Thanks guys.
