Independent Plumbing & Heating Specialists You Can Trust
OnTime – Complete Maintenance Solutions is an independent plumbing and heating business run by Kemal Mustafa (Kem), a Gas Safe registered engineer providing professional services throughout Chislehurst, Bromley, Greenwich and surrounding areas of South East London and Kent.
We believe good workmanship, honest advice and reliable service should come as standard.
At OnTime, customers benefit from a personal, engineer-led service rather than the impersonal approach of a large national company. From the initial enquiry through to completion, our approach is straightforward: understand the problem, explain the available options and carry out the work properly.
Across 95+ verified homeowner reviews since October 2021.
Manufacturer warranties available on selected new boilers, depending on the manufacturer, boiler selected and applicable terms.
Experience, Knowledge & Professional Standards
We specialise in domestic boiler installations, fault diagnostics, repairs, servicing, central heating systems, hot water cylinders and gas safety inspections.
With Gas Safe registration, G3 qualifications for unvented hot water systems and Ideal Max Accredited Installer status, we have the technical knowledge to work on a wide range of heating and hot water systems.
We work with leading manufacturers including Ideal, Vaillant, Worcester Bosch, Baxi and Viessmann, recommending solutions based on the requirements of each property rather than promoting one particular brand.
Honest Advice Without Unnecessary Sales Pressure
Not every boiler fault requires a new boiler, and not every heating problem requires an expensive replacement.
We believe in identifying the cause of a problem before recommending the appropriate solution.
Whether it's a straightforward repair, routine maintenance or a complete heating system upgrade, we'll explain our findings, discuss the available options and provide clear pricing before additional work is undertaken.
Our aim is to deliver dependable, long-term results rather than simply the quickest or cheapest solution.
