I couldnt recommend Peter from Dulwich Gas & Heating Specialists enough. My gas hob was shut of by Southern Gas Networks after I reported a gas leak. I decided to replace the hob instead of trying to get it fixed. Peter gave me a rough cost on installation across the phone. He arrived at the time he said he would. Replaced hob. Provided certificate for the installation. Also took away my old hob at no extra cost. Peter 07999290257
