S. Harrow Plumbing, Heating & Bathroom Merchants has been a cornerstone of the South Harrow trade community since 1985. What started as a small plumbing supplies counter on Station Parade has grown into one of the area's most comprehensive merchants.
We supply professional plumbers, heating engineers, bathroom fitters, and DIY homeowners alike. Our team has hands-on trade experience — we understand what you need on the job and stock accordingly.
From a single compression fitting to a full boiler installation kit, we pride ourselves on having it in stock today, not next week.
