Georgian Camberwell, Victorian East Dulwich and riverside Bermondsey
Southwark reaches from the Thames at Bankside and Bermondsey down to Dulwich, and its housing changes a great deal along the way. Camberwell Grove, Grove Lane and Addington Square keep well preserved Georgian houses. East Dulwich was built up at speed, with more than 5,000 houses going up between 1871 and 1881, and many of those along and around Lordship Lane have since been converted into flats.
By the river, the old warehouses of Shad Thames and Butler's Wharf became flats and offices from the 1980s, and Bankside has newer residential towers such as Triptych Bankside, finished in 2023. Large post-war estates complete the picture. The Aylesbury Estate in Walworth, built between 1963 and 1977 with 2,704 homes, is being rebuilt in phases, and the Brandon Estate was begun by the London County Council in 1958 around six 18 storey towers.
Heat networks on Southwark's council estates
Southwark Council runs more than 100 heat networks, supplying heating and hot water to around 17,000 homes. Several Bermondsey estates, among them the Four Squares and Silwood estates, take their heat from SELCHP, the South East London Combined Heat and Power plant, and the council plans to connect more homes around the Old Kent Road and North Peckham.
If your flat is on one of these networks, loss of heating or hot water is for the council to investigate, so report it through the council's repairs line first. A leak inside the flat is a separate matter. A failed joint under a bath or behind kitchen units can mark the ceiling below whatever the heat source, and the survey begins by checking whether your own water pipes are losing water.
Warehouse flats in Shad Thames and new towers at Bankside
Warehouse flats in Shad Thames and along Bermondsey Street tend to have thick masonry walls, heavy floors and pipework boxed in against the old structure. A slow leak can soak into boxing or a raised floor and stay out of sight until a neighbour reports a stain. For heating and hot water in buildings like these, thermal imaging, from £150, is the usual first step.
Newer riverside blocks generally have plastic pipes set in screed, sometimes with underfloor heating, and leaks in them make very little noise. Tracer gas, from £200, finds cold plastic pipe, and underfloor heating surveys cost £300 to £700. Shops, restaurants and offices, including those underneath flats, are covered by commercial detection from £300.
In older converted buildings, heat may come from a boiler in each flat or from shared plant in the basement, and that decides where the search starts. With a boiler, a falling pressure gauge points to the heating circuit. With shared plant, the managing agent needs to be involved from the outset.
Supply pipes in Camberwell and East Dulwich houses
Thames Water supplies Southwark and looks after its own network as far as the outside stop valve. From there, the supply pipe is the owner's. In a Camberwell or East Dulwich house split into flats, a single supply often feeds every home, so its upkeep is shared between the owners. Houses built before about 1970 can still have lead on this stretch, and joints often give way where the pipe rises through the floor.
Indoors, the usual finds are a weeping joint below an upstairs bathroom, heating pipes notched through joists, and a pipe buried in the floor of a rear extension. Acoustic detection, from £150, suits a supply pipe under a tiled front path. A trace and access survey, from £350 to £450, gives neighbours and freeholders a written record from which to agree the repair.
Getting a Southwark home ready for the engineer
Take two meter readings an hour apart with nothing running, test that your stop tap turns, and keep a record of the boiler pressure if you have your own boiler. Council tenants should report a suspected leak to the council before anything else, and leaseholders should look at which pipes their lease makes theirs.
Let the flat below know, since their ceiling may show the leak before your floor does. For water escaping right now, emergency detection is priced from £300 in working hours and £450 at night, at weekends and on bank holidays. To book a survey, ring 020 3912 0200.

Leak Detection in Southwark: Common Questions
Do you cover Bermondsey, Camberwell, Peckham and Dulwich?
Yes, we cover the whole London Borough of Southwark, including Bankside, Borough, Bermondsey, Rotherhithe, Walworth, Elephant and Castle, Camberwell, Peckham, Nunhead, East Dulwich and Dulwich. The same methods and published prices apply throughout, from riverside apartments and warehouse flats to Victorian terraces and council estates.
My Southwark council flat is on district heating. Who is responsible if the heating leaks?
Faults on the heat network are the council's responsibility, so report loss of heating or hot water to Southwark Council first. The council runs more than 100 networks across the borough. If water is appearing in your flat or the one below and nobody is sure of the source, we check your pipes for loss and record in the report which pipe is at fault.
Water is coming into my Shad Thames warehouse flat. Where does the search start?
With the most likely sources above and around the wet area, which in a warehouse conversion often means boxed pipework, a bathroom on the floor above or a riser. We check whether your supply and heating are losing water, then follow the moisture with thermal imaging and acoustic equipment. Tell the managing agent in advance, as access to other flats or shared areas may be needed.
Who is responsible for the supply pipe in a converted East Dulwich house?
Thames Water is responsible up to the outside stop valve, usually under a cover near the pavement. Beyond that valve, a supply pipe feeding several flats belongs jointly to the owners it serves, and the lease or freehold terms normally explain how costs are split. Our written report marks the leak position, so every owner is working from the same evidence.
