Understanding boiler servicing in Southwark
For landlords, an annual gas safety check is a legal requirement — not a boiler service. For homeowners, neither is a legal requirement.
The Gas Safety (Installation and Use) Regulations 1998 require landlords to arrange an annual gas safety check by a Gas Safe registered engineer for all gas appliances they provide to tenants — the legal requirement is the safety check specifically, not a broader service.²
The HSE confirms landlords are responsible for maintaining gas appliances, pipework and flues in a safe condition — and must arrange an annual gas safety check by a Gas Safe registered engineer.³ The resulting Landlord Gas Safety Record must be kept for at least two years and provided to existing tenants within 28 days of the check and to new tenants before they move in.³
For homeowners not renting out their property, regular servicing is widely recommended to maintain safe and efficient operation — though it is not a legal requirement. Manufacturers typically require servicing in line with their instructions as a condition of maintaining the boiler warranty.
What a boiler service in Southwark includes
A Gas Safe registered engineer will typically carry out:
- Visual inspection of the boiler and components
- Checking the heat exchanger, burner and seals
- Testing flue integrity and emissions
- Checking pressure, water flow and controls
- Inspecting the gas supply and safety devices
- Confirming the boiler fires and operates safely
Your engineer should complete a Benchmark service record at each annual visit — commonly required by manufacturers to keep the warranty valid.¹
The Landlord Gas Safety Record — what Southwark landlords need to know
If you rent out a property in Southwark, the annual gas safety check is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998.²
The HSE confirms the Landlord Gas Safety Record must still be issued even if defects are identified.³ It applies to all gas appliances provided for tenant use — not just boilers — and must include the engineer’s Gas Safe registration number, the date of the check, the address of the property and details of any defects identified.
You must provide a copy to existing tenants within 28 days and to new tenants before they move in.³
Before your engineer attends, ask to see their Gas Safe ID card and verify their current registration at gassaferegister.co.uk.¹
Annual boiler service Southwark: ex-council homeowners
If you own an ex-Southwark Council property, you can use the council’s own Gas Safe engineers for your annual boiler servicing in Southwark.
Southwark Council’s gas servicing package costs £120.67 including a £46.20 admin fee — at time of writing.⁵ You receive a gas safety check, your boiler serviced, an inspection of any other gas appliances (like fires and heaters), and a Gas Safe certificate if the appliance passes safety standards.
This option is available specifically to ex-council homeowners. Private homeowners and landlords can use any Gas Safe registered engineer — including those listed here.
Hard water and boiler servicing in Southwark
Southwark sits in Thames Water’s hard water area. Thames Water confirms hard water causes limescale build-up on household appliances and fittings — which can affect heating system components over time.⁴
We recommend asking your engineer to carry out an inhibitor check as part of any annual boiler servicing in Southwark — and to top up or replace the system inhibitor if required. A central heating filter inspection at the same time helps confirm the system is running clean between services.
Southwark housing stock — practical context for boiler servicing
The practical context of a boiler service can differ widely depending on where in Southwark you are. 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 terraced stock — Peckham SE15, Camberwell SE5, Nunhead SE15, East Dulwich SE22, Dulwich SE21. Properties of this era can retain older heating systems — sometimes with remnants of original gravity-fed setups, ageing cylinders or older flue routing. Service visits in older terraces often take longer than in modern stock, particularly where access to the boiler, flue or cylinder is restricted. Mention the property type when you call so the engineer can allow enough time.
Purpose-built flats and estate stock — SE1, SE5, SE15, SE16, SE17. Many flats across the borough have individual combi boilers in kitchen or bathroom positions with constrained access. Annual service visits are typically straightforward but flue inspection can be limited where flues route through structural walls or terminate in shared external positions.
Bermondsey and Rotherhithe SE16 wharf and warehouse conversions. Conversions can have concealed flue runs and unusual boiler positions (e.g. in plant cupboards or service voids). Mention the property type when you call so the engineer can plan adequately for any flue or access challenges.
Aylesbury Estate, Heygate replacement and Old Kent Road regeneration — Walworth SE17, Elephant & Castle SE17, Old Kent Road SE1/SE15. New-build flats in this corridor may have heat interface units (HIUs) rather than individual combi boilers. HIUs are not gas appliances and do not require Gas Safe servicing — they’re maintained by the heat network operator or appointed contractor under the building’s maintenance contract. Confirm what kind of system you have before booking a Gas Safe service.
Bankside, Borough and London Bridge SE1 mansion blocks and mixed-use buildings. Period mansion blocks above commercial parades can have shared flue arrangements where annual flue inspection is part of the service. Your managing agent or block freeholder may hold records of previous services that help establish service history.
Southwark Council housing portfolio — and ex-council homeowners. Council tenants do not need to book private boiler servicing — Southwark Council services its own stock via appointed contractors. Ex-council homeowners (leaseholders or freeholders of former council properties) can use Southwark Council’s Gas Safe engineers via the council’s gas servicing package (see section above), or any Gas Safe registered engineer including those listed here.
Dulwich Estate and conservation areas — Dulwich SE21, East Dulwich SE22, Camberwell SE5, Peckham SE15. Annual servicing itself doesn’t normally trigger planning considerations, but if a flue inspection during the service identifies the need for flue replacement or repositioning, conservation-area restrictions can apply to external flue changes on listed or locally-listed buildings. Worth knowing in advance.
Private tenants in Southwark — your rights on gas safety
If you are a private tenant, your landlord is legally required to arrange an annual gas safety check for all gas appliances they provide, and to give you a copy of the current Landlord Gas Safety Record.²³
If your landlord or agent fails to arrange the check or provide the record, contact Southwark Council’s private sector housing enforcement team.⁶ The council aims to respond within 2 working days, or the next working day for urgent problems.
