About plumbing in the London Borough of Croydon
Croydon is one of London’s largest boroughs by population, stretching from Thornton Heath, Norbury and South Norwood in the north down through Croydon town centre and Addiscombe to the outer suburbs of Purley, Coulsdon and Sanderstead in the south.
Its housing stock is unusually varied. Northern Croydon is dominated by Victorian and Edwardian terraces — particularly in wards such as Thornton Heath, South Norwood, Selhurst, Addiscombe and Norbury, which have a high concentration of pre-1914 and pre-war stock. Central and southern Croydon is dominated by inter-war semi-detached stock across Purley, Coulsdon and Sanderstead, with post-war and more recent development interspersed throughout.
Property ages, system types and plumbing configurations vary significantly across the borough. Understanding which type of property you are working on — and what plumbing system, drainage configuration and water hardness level it may carry — is what separates a plumber in Croydon who knows the borough from one who does not.
What Croydon properties may present — key considerations
Pre-1914 and inter-war properties
Older properties in Thornton Heath, South Norwood, Norbury, Addiscombe, Selhurst and Woodside may carry gravity-fed hot water systems, original copper pipework, lead supply pipes, imperial-sized fittings and isolation valves that have not been operated in years.
A plumber attending an older Croydon property should be alert to the possibility of seized valves, scaled cartridges, unmodernised drainage and loft cold water tanks that may not have been inspected recently. Confirming the hot water system type before specifying any shower, bathroom or heating installation is essential.
Water supply across Croydon — Thames Water and SES Water
Croydon Council confirms clean-water supply across the borough is split: Thames Water supplies clean water to the majority of the borough, while SES Water (Sutton & East Surrey) supplies the southern part.¹¹ Check which supplier serves your specific postcode before relying on supplier-specific contacts or pipe responsibility frameworks. Thames Water serves sewerage and wastewater for the whole borough.
Lead supply pipes — where found
Both Thames Water and SES Water advise that lead pipes can affect drinking water quality and recommend replacement where they are identified.¹ Lead supply pipes can be found in older unmodernised properties across the borough, particularly in the pre-1914 stock concentrated in the northern wards.
For Thames Water-supplied properties, Thames Water is responsible for the communication pipe between its main and your property boundary; property owners are responsible for the supply pipe from the property boundary into the home, and for all internal pipes and fittings.² For SES Water-supplied southern Croydon properties, equivalent pipe-responsibility rules apply with SES Water as the supply undertaker; check the SES Water website for their pipe-responsibility framework.¹²
A kitchen or bathroom refit is often a practical opportunity to identify and replace any remaining lead pipework.
Hard water — across Croydon
Hard water is documented across both Thames Water and SES Water supply zones. Thames Water confirms that limescale deposits on household appliances and fittings are a documented consequence of hard water in its supply region.¹ SES Water publishes postcode-level water hardness reports — southern Croydon postcodes should be checked against the SES Water postcode report for the local water hardness reading.¹³
Limescale may accumulate on tap cartridges, shower valves, cistern inlet valves and boiler heat exchangers. Hard water scale can increase maintenance needs in outlets and fittings.
HSE guidance stresses temperature control, flushing infrequently used outlets and cleaning and descaling showerheads as part of Legionella risk control (HSE guidance).⁵
Inter-war semi-detached stock — Purley, Coulsdon and Sanderstead
Inter-war semis across CR2, CR5 and CR8 may carry gravity-fed hot water systems with cold water storage tanks in the loft, cylinders in airing cupboards and pipework runs through solid floors. System conversions to combi boilers are common but often retain pipework routes reflecting the original layout — ask the engineer to confirm the current system configuration before specifying new work.
Converted and purpose-built flats
Converted and purpose-built flats across Croydon town centre and pockets of Addiscombe, Thornton Heath and South Norwood may carry shared soil stacks, communal supply risers and managing agent responsibility for shared services.
Bathroom and kitchen plumbing work in these buildings may require confirming managing agent consent and identifying correct isolation points before any work begins.
Thames Water is responsible for public sewers and public lateral drains. Property owners are responsible for drains serving only their property within their boundary (Thames Water guidance).²
Council-owned properties
Croydon Council holds a significant social housing stock across the borough. Plumbing work in council properties is handled through the council’s repair routes, not privately. Council tenants should contact Croydon Council’s repairs contact centre on 020 8726 6101 — routine repairs Monday to Friday, 8am–6pm; emergency repairs can be reported any time.⁸ Private plumbing alterations in council properties should not be arranged without written permission.
Landlords in Croydon — your key plumbing obligations
Repairs and maintenance
Section 11 of the Landlord and Tenant Act 1985 requires landlords to keep in repair and proper working order the installations in the dwelling-house for the supply of water, gas and electricity and for sanitation — including basins, sinks, baths and sanitary conveniences.³
Tenants should first notify the landlord in writing and keep evidence of the disrepair before escalating. If a landlord fails to address reported disrepair within a reasonable time, the tenant may report it to Croydon Council’s Private Sector Housing Team, which may inspect and take enforcement action where hazards or breaches are identified.⁹ Contact Croydon Council’s Private Sector Housing Team on 020 8760 5476.
Annual Gas Safety Check — landlord legal duty
It is illegal for anyone not Gas Safe registered to carry out gas work (HSE guidance).⁴ Under the Gas Safety (Installation and Use) Regulations 1998, landlords must arrange an annual Gas Safety Check of all relevant gas appliances and flues by a Gas Safe registered engineer who is competent for the specific appliance type.
The legally required document produced is the Gas Safety Record — ‘CP12’ is an industry term and not used in legislation. A boiler service is a separate maintenance activity and does not fulfil the Gas Safety Check legal duty on its own.
Landlords must issue a copy of the Gas Safety Record to each existing tenant within 28 days of the check, and to any new tenants before they move in (HSE guidance).⁷
Landlords can arrange the Gas Safety Check up to two months before the current record expires while retaining the original expiry date — this protects the renewal cycle without losing compliance days.
HMO and selective licensing — changing from September 2026
Croydon currently operates the Mandatory HMO Licensing Scheme borough-wide for HMOs with 5 or more occupants forming 2 or more households.¹⁰
Croydon Council’s Cabinet has approved two further schemes which come into force on 1 September 2026:
- Additional HMO licensing — borough-wide, applies to HMOs with 3 or more occupants forming 2 or more households that are not already covered by mandatory licensing¹⁰
- Selective licensing — 14 designated wards, applies to all privately rented homes (excluding HMOs) in those wards¹⁰
Both schemes were designated on 25 March 2026 and run for 5 years. Landlords should check the current Croydon licence conditions, including any gas safety evidence required for their property type.
Check Croydon Council’s landlord licensing page to confirm whether your property requires a licence — licensing schemes can change and the council page carries the current position.
Legionella risk
Landlords have a legal duty to assess Legionella risk in the course of their letting activities — which constitute a business activity — under the Health and Safety at Work etc. Act 1974 and, where applicable, the Control of Substances Hazardous to Health Regulations 2002 (HSE guidance).⁵
HSE Approved Code of Practice L8 provides the practical guidance for meeting that duty. Landlords must identify, assess and control Legionella risk. In simple low-risk domestic properties, this may be a basic assessment by a competent person rather than a paid specialist assessment.
For HMOs with stored water systems, hot water cylinders and infrequently used outlets, the risk is higher. These may require input from a competent person with appropriate knowledge of Legionella risk control — not just standard plumbing remedials (HSE ACoP L8 guidance).⁵
HSE guidance stresses temperature control, flushing infrequently used outlets and cleaning and descaling showerheads as part of Legionella risk control. Properties left vacant for extended periods require specific attention before occupation resumes.
The London Landlord Plumbing Compliance Checklist covers all of these obligations in full.
Croydon postcodes — area reference
CR0 — Croydon town centre, Addiscombe, Shirley, Woodside, New Addington
Croydon’s largest postcode by area and population. Mixed stock from Victorian terraces (Addiscombe, Woodside, parts of central Croydon) to post-war council estates (New Addington) and purpose-built flats in and around the town centre. Converted flats may carry shared stacks and managing agent considerations. Hard water area — predominantly Thames Water-supplied, though confirm against your specific postcode as supply is split across the borough. Limescale impact may be present. Confirm hot water system type before specifying heating or bathroom work.
CR2 — South Croydon, Sanderstead, Selsdon
Mixed inter-war semi-detached stock with some older stock closer to the town centre. Hard water area — clean-water supplier may be Thames Water or SES Water depending on specific postcode location; check before relying on supplier-specific contacts. Limescale impact may be present. Unmodernised properties may carry gravity-fed systems and original pipework configurations.
CR5 — Coulsdon, Old Coulsdon, Kenley
Inter-war and post-war semi-detached and detached stock. Some properties on the outer edges may have longer supply pipe runs which can increase leak risk. Hard water area — southern Croydon properties may be SES Water-supplied rather than Thames Water; check your specific postcode for the correct clean-water supplier before relying on supplier-specific contacts. Limescale impact may be present.
CR7 — Thornton Heath
Dominated by Victorian and Edwardian terraced stock; Thornton Heath has one of the highest concentrations of pre-war housing in the borough. Older properties may carry original clay drainage, cast iron soil stacks, imperial-sized fittings and lead supply pipes. Thames Water advises replacement of lead pipes where identified.¹ Landlords should confirm licensing obligations with Croydon Council, particularly given Additional HMO Licensing from 1 September 2026.¹⁰
CR8 — Purley, Kenley, Whyteleafe
Predominantly inter-war semi-detached stock with some post-war development. Gravity-fed hot water systems may still be present in unmodernised properties. Hard water area — southern Croydon properties may be SES Water-supplied rather than Thames Water; check your specific postcode for the correct clean-water supplier before relying on supplier-specific contacts. Limescale impact may be present.
SE25 — South Norwood, Selhurst, Woodside
Heavily concentrated Victorian and Edwardian terraced stock across Selhurst, South Norwood and Woodside. Older properties may carry original clay drainage, cast iron soil stacks and lead pipework. High private rented sector concentration — Additional HMO Licensing applies borough-wide from 1 September 2026 and Selective Licensing may apply depending on the specific ward.¹⁰
SW16 — Norbury, Pollards Hill, Streatham Vale
Predominantly Victorian and Edwardian terraced stock; Norbury and Pollards Hill have a high concentration of pre-war housing. Older properties may carry gravity-fed systems, original clay drainage and lead supply pipework.
How we verify plumbers on this directory
Every plumber we list passes our verification process before going live.
Important limitations: Our verification is an editorial process — not a regulatory or statutory standard. We are not a regulator and we do not adjudicate disputes between users and listed traders. Our verification is point-in-time at the date of listing. We do not monitor ongoing compliance or workmanship after listing. Our verification does not guarantee ongoing compliance or workmanship quality. Listings are re-verified on renewal — any listing that cannot be re-verified is removed.
Identity — We review evidence of business identity and trading name against documents supplied at onboarding, including company registration or sole trader records.
Insurance — We review evidence of current public liability insurance against documents supplied at onboarding. We review evidence supplied — we do not underwrite or guarantee coverage.
Gas Safe registration — For gas work pages, we check registration against the live Gas Safe Register at time of listing using the engineer’s current 7-digit licence number from their current ID card. It is illegal for anyone not Gas Safe registered to carry out gas work (HSE guidance).⁴ Registration status can change when a new annual card is issued — HSE says it is your responsibility to check the engineer’s current registration and to check the back of the ID card for the correct appliance categories before work begins.
WaterSafe registration — Where held, we review WaterSafe/approved contractor evidence and ask the installer to confirm whether the work falls within the scope of that approval. Certain plumbing works require prior notification to the water undertaker under Regulation 5 of the Water Supply (Water Fittings) Regulations 1999.⁶ In some cases, an approved contractor may carry out notifiable work without prior notification and must issue a certificate of compliance on completion under Regulation 6, where the work falls within the scope of their approval. Homeowners should not assume work is exempt — the installer must confirm whether notification or certification is required for the specific work.
Reputation — We carry out a manual cross-platform review check across Google, Yell, Checkatrade and Trustpilot at time of listing. Patterns of poor reviews, unresolved complaints or unexplained gaps in trading history are grounds for rejection. This is an editorial check — not a Trading Standards or statutory assessment.
Service area — We confirm coverage of the relevant postcode areas before a listing goes live. Coverage varies by listing — check each listing for the specific areas covered.
Corrections and complaints — If you believe a listing is inaccurate or a trader has behaved improperly, contact us directly via the site contact page. We are not a regulator and do not adjudicate disputes. Where a complaint is upheld, our action is limited to removing or restricting the listing. We aim to review complaints within five working days. Rogue trader concerns should additionally be reported to the Citizens Advice Consumer Service on 0808 223 1133.

Typical plumbing costs in Croydon — 2026
Internal editorial estimate based on directory data. Prices are editorial estimates, not quotes from every listed plumber. Prices vary by property type, access and system complexity. Emergency rates typically increase outside standard hours. VAT may apply.
Most plumbers can quote remotely for straightforward jobs (tap, toilet, washer, dishwasher connection) from a description and photos. Larger work — bathrooms, kitchens, boiler installs, pipework changes — usually needs a site visit to quote accurately. Ask whether the figure is a fixed price or a starting estimate, whether callout is included, and whether parts are itemised separately. Always obtain a written quote before work starts.
| Service | Typical range (London 2026) |
|---|---|
| Hourly rate (plumber) | £65–£105 |
| Emergency callout | £120–£180 (first hour) |
| Annual boiler service | £100–£130 |
| Landlord Gas Safety Check + Gas Safety Record | £120–£160 |
| Boiler installation (combi, like-for-like) | £2,800–£4,500 |
| Bathroom installation (plumbing only) | £1,500–£4,500 |
| Kitchen plumbing (full installation) | £500–£2,500 |
