 Trustindex verifies that the original source of the review is Google. Used Alex as a local based plumber to fix an issue with the taps. He knew what the issue was likely to be and came prepped on the first visit, but sadly after opening the taps up it was a full replacement required, but Alex ordered the replacements and fitted the new taps a week later quickly and to a high standard.

 Trustindex verifies that the original source of the review is Google. Very efficient. Our boiler was v old and basically about to go bust. Previously used British Gas, who were useless - signed off the boiler without even looking at it, whereas Alex was fully and transparent, came originally and realised it was a much larger job, didn't charge came back and spent hours fully fixing and repairing. Saved us having to buying a new boiler. Would highly reccommend

They really proved their worth on a major project where another plumber had completely let me down.

 Trustindex verifies that the original source of the review is Google. Our boiler suddenly stopped working on a freezing morning. I contacted UK Gas Engineer Ltd  and they had an engineer out the same day. He quickly found the fault explained everything in simple terms and had the heating back on within the hour. Fantastic service.
