Just waved goodbye to stephen, who attended promptly, thoroughly, and professionally cleared a big problem arising from years of neglect a real treat to witness such amazing customer service and diligence! From boilers and central heating, quality every time. We would highly recommend all koegel plumbing services without hesitation! Just a quick note to say how good the worcester boiler is and thanks for fitting it; great set of lads they didn't leave a mess either - great work". We are.
