Recommend a central heating engineer/plumber in Hackney please?

[AlysGriffin]

I need to replace a gas boiler and a toilet - can anyone recommend a good CORGI registered heating engineer and a plumber please?

I have used www.goflow.co.uk loads for plumbing work. I feel very comfortable with them as they are decent, trustworthy, young, intelligent and reliable. I haven't compared prices for years because I have used them, so i can't comment on whether they are pricey or not. Worth getting a quote from.
Don't know about the heating engineer side.
