Boiler service and advice.

“Once again, reliable polite and efficient company. Will use for all my plumbing needs.”

– Customer in Ilford (1) 16 May 2019


Several plumbing jobs

Easily the most professional plumbing firm I have used. Had a good feeling when the owner and staff donned plastic shoe covers without being asked - and then again every time they re-entered the property.
4 different plumbing jobs all done on the same day, including the replacement of heating/hot water controls and the untangling of a lot of mess which previous plumbers failed to fix. For the first time in years it all works. This is now my go-to firm for any serious work that needs doing.
Felt like they knew what they were doing at all times. No hidden extras.

Old boiler removed and new boiler installed.

The work was done in a day, on time, tidy as ever and they even positioned the new boiler so as not to disrupt the sealed flat roof above. Very pleased with their work. The new Vaillant boiler had an ignition fault requiring an engineer from there to replace 3 new parts which spoil things.

Boiler installation

"Excellent service, had a problem with our boiler and from first phone call to completion of installation of took about a week. Costin and his team were just what you would want for contractors in your house. Wore overshoes all the time, laid out floor protection, turned up when they said they would, left the house as the found it (apart from a boiler that works). The day after completion I received by email the 10 year guarantee cert from the boiler manufacture, the gas safe certificate and the benchmark documents to say the installation was as per the instruction manual. Could not fault the way the job was run and completed. Highly recommended."

Power shower revamped and new toilet.

“Very happy with the work. Would recommend anyone get a quote from this company. Costin, the plumber, is a very knowledgeable, helpful and friendly chap. The guys who Costin subbed out the tiling to were equally professional. Everything is working perfectly, but I'm confident if there were issues I wasn't happy about, Costin would be back to sort them out. Not sure how this company compares price wise. I did get a few cheaper quotes via another comparison website but these didn't feel me with confidence. I didn't want the cheapest, I wanted quality and value. And I wasn't disappointed!”

Costin and his father-in-law arrived to undertake the work at the agreed time and date and they were careful to put down floor protection. The job was carried out calmly and efficiently giving us confidence in the work being done. Team Lazard Plumbing Heating and Gas were courteous and polite at all times and communication was excellent before, during and after the work was completed, thanks also to Renata. If you need a reliable, professional plumbing and heating engineer I recommend Lazard Plumbing Heating and Gas unreservedly.”

Everything with Lazard is so simple - Lazard are simply very good.”
