From a leaking pipe in a basement flat off Clapham Common to a full boiler replacement in a Victorian townhouse near Abbeville Road — our Clapham plumbers cover every type of job across SW4 and the surrounding area.

Plumber repairing burst pipe — emergency plumbing service South London TopFix

Burst Pipes & Water Leaks

Burst pipes in Clapham’s converted Victorian terraces often run through shared wall spaces or along routes that aren’t immediately accessible. We respond the same day across SW4 and SW11, locate the source and carry out a proper repair — checking whether the fault is within your property or in shared pipework affecting other flats in the building.

Plumber repairing leaking tap and replacing mixer — TopFix South London

Dripping Taps & Tap Replacement

Clapham’s mix of rental flats and owner-occupied conversions means we see everything from original period fittings to budget taps installed during a quick refurb. We identify the actual fault first — worn cartridge, failed seal or incompatible fitting — and fix it properly, whether that means a repair or a full replacement.

Plumber diagnosing low water pressure at pipework — TopFix South London

Low Water Pressure

Low pressure is common in Clapham’s HMOs and shared properties where the incoming supply is split between multiple flats drawing simultaneously. We diagnose the actual cause — faulty PRV, shared supply limitation or stopcock issue — and advise honestly on what can be fixed within your property and what falls outside it.

Gas Safe engineer diagnosing boiler fault — no hot water repair South London TopFix

No Hot Water

Clapham’s high proportion of shared rental properties means boilers run at higher usage levels than in single-occupancy homes — which accelerates wear on components like diverter valves and heat exchangers. Our Gas Safe engineers identify the fault on the first visit and carry common replacement parts for all major brands on the van.

Plumber fixing overflowing sink and pipe leak — TopFix South London

Overflowing Sinks & Baths

Blocked wastes are among the most common callouts we receive from Clapham landlords and tenants — particularly in HMOs where drainage is shared and blockages affect multiple occupants at once. We clear the blockage, test the full drainage run and confirm everything is flowing correctly before we leave.

Engineer repairing heating system controls and pipework — TopFix South London

Radiator & Heating Pipe Issues

Cold radiators and noisy heating pipes are common in Clapham’s converted properties where the original single-house system was divided between flats without being properly rebalanced. We bleed, balance and repair across SW4 — and give an honest view on whether a power flush is worth it based on what we find in the system.

Our advantages

Why Clapham residents choose TopFix

Clapham is one of the most densely populated parts of South London — a mix of large Victorian and Georgian townhouses that have been divided into flats, basement conversions, purpose-built mansion blocks and a growing number of refurbished period homes. That variety creates a wide range of plumbing demands, and it's something our team handles every week.

Converted properties in particular can be tricky — shared pipework between flats, drainage that was never designed for multiple bathrooms and boilers tucked into cupboards that haven't been serviced in years. We know what to look for and how to fix it without making a simple job complicated.

Consistent reviews from Clapham customers and fast response times across SW4 have made TopFix a go-to plumbing service for homeowners, landlords and letting agents across the area.

Frequently asked questions

How fast can you get to Clapham?

For emergencies — usually within the hour. SW4 is well within our area so there's no long wait. For everything else, same day is normally doable, next day if not.

Converted flats, HMOs — do you deal with that kind of thing?

That's basically half our work in Clapham. Converted Victorians, basement flats, houses split into four units with plumbing that's been bodged together over twenty years — we've seen the lot. Shared pipework, drainage that runs through three flats before it gets outside, systems nobody's touched since the conversion. We know what we're looking at.

Which parts of Clapham do you cover? All of SW4

Common, High Street, North, South, Abbeville Village. We also go out to Balham, Brixton and Stockwell regularly. Not sure if you're in range? Just call and we'll tell you.

Gas Safe?

Yes. Registered. Every boiler and heating job, no exceptions. Details available on request.

Expert Plumbers Serving Clapham

Clapham keeps plumbers busy — and it keeps them honest. With so many converted flats, shared drainage systems and boilers that are well overdue a service, there's no shortage of work here. What there is a shortage of is plumbers who turn up when they say they will, charge what they quoted and fix the problem rather than mask it.

That's what we focus on at TopFix. We work across all of Clapham's housing types — the large Georgian and Victorian townhouses around Clapham Common that have been converted into flats, the basement conversions off Clapham High Street, the mansion blocks near Clapham North and the period terraces in Abbeville Village that are still single-family homes. Each comes with different plumbing demands, and our team is experienced with all of them.

Our Clapham plumbers are Gas Safe registered, fully insured and used to working in occupied properties where disruption needs to be kept to a minimum. Whether you need an emergency repair at short notice or a bathroom installation planned weeks ahead — we get it done properly, with no shortcuts and no surprises when the invoice arrives.
