Every listing is verified at time of listing — Gas Safe registration checked against the Gas Safe Register where applicable, evidence of public liability insurance checked, business identity and named contact validated.
Most dripping or stiff taps are repair jobs with inexpensive parts (washers £1–£3, ceramic cartridges £10–£30); replacement is usually only needed where the tap is corroded, broken or past repair. Many are within DIY scope if the isolating valve works. If the valve is seized, the tap is corroded solid, or the base is leaking, call an engineer. No call centres, no middlemen — you describe the tap type and symptom (photos often help — you don’t need to identify the exact part), confirm price and parts, and book direct.

Understanding tap repair and installation in Croydon
Common tap faults and what they mean
Traditional taps (separate hot and cold, rubber washer)
- Dripping from the spout — worn rubber washer. Cheap fix once the tap head is off. In hard water areas, the spindle seat may also need re-grinding.
- Leaking from under the handle — gland packing worn; replace or re-pack.
- Stiff handle — scale on the spindle thread. Descale or replace.
Monobloc / mixer taps (single lever, ceramic cartridge)
- Dripping from the spout — worn ceramic cartridge. Cartridges are often brand-specific and not interchangeable — take the old one to the merchant or order online by tap make/model.
- Leak at the base when running — O-ring on the spout swivel, or cartridge seal.
- Handle hard to move — cartridge worn; replacement needed.
All tap types
- Low flow — check the aerator (unscrew the end of the spout and clean the mesh). Scale is usually the cause.
- No flow at all — isolating valve fully closed, or blocked. Check under the sink first (the small valve on the pipe feeding the tap, usually turned with a flathead screwdriver) before calling an engineer.
- Tap wobbling on the sink — the fixing nut underneath has come loose. Usually a straightforward tighten.
Hard water and tap wear in Croydon postcodes
Clean-water supply across Croydon is split. Croydon Council confirms Thames Water supplies clean water to the majority of the borough while SES Water (Sutton & East Surrey) provides clean water to the southern part of the borough.⁴ Thames Water confirms hard water can lead to limescale build-up on household appliances and fittings.¹ SES Water publishes postcode-level water hardness reports — southern Croydon postcodes should be checked against the SES Water postcode report for specific hardness in your area.⁵
In practice, this means:
- Aerators clog — the fine mesh at the end of the spout fills with scale, reducing flow. Unscrew and soak in white vinegar or descaler.
- Ceramic cartridges seize — scale builds up around the moving parts. Lifespan is shorter than in soft-water areas.
- Chrome plating pits and dulls — scale and chemical descalers can both damage the finish over time.
- Isolating valves seize — valves that never get used can be impossible to turn when needed. Open and close them occasionally as part of annual plumbing checks.
A scale inhibitor on the mains supply won’t stop scale forming inside taps but may help reduce build-up in some systems, with effectiveness varying. Installing a water softener (separate job, significant cost) is the only way to remove hardness entirely.
Croydon housing stock — practical context for tap work
The practical context of a tap repair or installation differs widely by Croydon property type. The notes below are general observations to help frame a call to an engineer — your engineer’s site visit will confirm what your specific property actually has.
Pre-1914 Victorian and Edwardian terraces — Thornton Heath CR7, South Norwood SE25, Norbury SW16, Addiscombe CR0, parts of West Croydon and Selhurst SE25. Older terrace stock can retain a mix of original copper pipework, later imperial-to-metric retrofit work, and patched repair sections going back decades. Isolating valves under sinks are not always present or working in pre-1980 installations — confirm before booking, as a seized or missing isolating valve can mean draining down from the cold water tank or main stop tap.
Inter-war semis and 1930s housing — Purley CR8, Coulsdon CR5, Sanderstead CR2, parts of Shirley CR0 and Selsdon CR2. The semi-detached belt across south Croydon typically has gravity-fed hot water from a header tank in the loft and a hot water cylinder. Many older taps in this stock were sized for low-pressure gravity systems — fitting a tap designed for high-pressure mains can result in poor flow on the hot side. Check pressure ratings before purchase.
Post-war estates and tower blocks — Selhurst SE25, New Addington CR0, Shrublands CR0, parts of central Croydon CR0. Council and ex-council estate flats commonly share risers and have communal supplies — for council tenants, repairs go through the council via 020 8726 6101.² For leaseholders, check your lease terms before instructing a private engineer.
Modern flats and town-centre regeneration — East Croydon CR0, town centre CR0, Saffron Square CR0, Ruskin Square CR0. New-build flats around East Croydon typically have planned plumbing risers and isolated branch supplies, with modern monobloc mixer taps as standard. Cartridge replacement is more common than washer replacement on this newer stock.
Outside tap installations across Croydon. Whether you’re in a Purley semi with a long garden, a Coulsdon house with a side return, or a converted Bermondsey-style flat with a small patio, outside tap installation requires Water Regulations-compliant backflow protection — typically a double-check valve. The Water Supply (Water Fittings) Regulations 1999 require prevention of contamination of supplied water.⁷
Replacing a tap — what to expect
A like-for-like tap replacement in a standard sink or basin often takes 30–60 minutes in straightforward cases, assuming:
- the isolating valves under the sink work
- the existing pipe tails line up with the new tap
- the fixing nut can be undone (often the hardest part in old installations)
If any of those are wrong, the job can escalate: new flexible tails, a new isolating valve, or cutting off a seized fixing nut. Ask the engineer to confirm what’s included in the quote, and what’s charged extra if complications arise.
Choosing a tap: most UK sinks and basins use standard tap hole sizes, but always check compatibility. Check the minimum pressure rating (bar) against your system — a tap designed for high-pressure mains may perform poorly on a gravity-fed hot supply from a cold water tank (common in older Croydon properties with upstairs cylinders).
Some engineers hold a recognised Water Fittings Regulations qualification or belong to an approved plumber scheme such as WaterSafe — ask if required for your installation, particularly for outside taps or any work involving the cold mains supply.
Outside taps and garden tap installation
An outside tap is a separate supply taken off the cold mains, with backflow protection (typically a double-check valve) to stop garden water contaminating the drinking supply. Installation is often completed within a few hours in straightforward cases and should include:
- isolating valve on the new branch inside
- double-check valve compliant with Water Regulations
- freeze-proof bib tap or conventional tap with lagging
- through-wall fitting properly sealed
Installing a garden tap without appropriate backflow protection may breach the Water Supply (Water Fittings) Regulations 1999, which require prevention of contamination. A suitable device — typically a double-check valve — is usually required. Ask the engineer to confirm the arrangement.
Council tenants in Croydon — tap repair route
If you live in a Croydon Council home, tap repairs go through the council, not a private engineer.
Call 020 8726 6101 for Croydon Council repairs. The repairs contact centre is open Monday to Friday, 8am to 6pm for routine repairs; emergency repairs can be reported at any time of the day or night.² Non-emergency repairs can also be reported via the council’s online portal.
Private tenants in Croydon — landlord obligations
Tap repairs in a rented property are generally the landlord’s responsibility, as part of keeping water and sanitation installations in working order. Section 11 of the Landlord and Tenant Act 1985 requires landlords to keep in repair and proper working order the installations for the supply of water and for sanitation (including basins, sinks, baths and sanitary conveniences).⁶
Report the fault to your landlord or letting agent first, in writing.
If your landlord does not respond or gives an unreasonable response, contact Croydon Council’s Private Sector Housing Team on 020 8760 5476. The council uses the Housing Health and Safety Rating System to assess the hazards and risks in your home and, if they are serious, may be able to take action to get the landlord to complete work.³
Keep photographs, texts and emails — the council will ask to see evidence of what you reported and how your landlord responded.³

Frequently asked questions — Tap Repair & Installation Croydon
Traditional taps (with two handles for hot and cold) usually have rubber washers. Monobloc mixer taps (one lever) have a ceramic cartridge. Kitchen mixer taps are almost always cartridge-based; a dripping spout means a cartridge replacement.
If you’re not sure what type of tap you have, take a photo and describe it to the engineer when you call.
A like-for-like swap in a standard sink is typically 30–60 minutes if the isolating valves work and the fixing nut isn’t seized. Older Croydon properties with corroded fittings can take longer — ask for a scope-based quote rather than a fixed time.
A confident DIYer can often swap a tap if the isolating valves under the sink (small valves on the pipes feeding the tap, usually turned with a flathead screwdriver) work and the existing connections aren’t seized. The hardest part is usually the fixing nut underneath the sink, where access is tight.
If the valves are seized or you can’t turn off the water cleanly, call an engineer — cutting the water off at the main stop tap and draining the system is harder in older properties.
Not planning permission, but the installation must comply with the Water Supply (Water Fittings) Regulations 1999, including fitting appropriate backflow protection (typically a double-check valve). A competent engineer will handle this as standard. If you’re on a water meter, an outside tap may affect your billing.
