Regeneration

Lewisham town centre, Catford and Deptford are adding new flats with communal plant, HIUs, fan coil units and MVHR.

Selective licensing

The borough's private rented homes are covered by a selective licensing scheme that began on 1 July 2024.

One contractor

We cover Lewisham from our Westminster office: one contractor, one schedule and one set of records for every unit, new-build block or portfolio of converted flats.

Heat networks and new districts in Lewisham

SELCHP, the energy recovery facility in south-east London, is operated by Veolia, which already supplies heat from it to Southwark Council estates.

01 · North Lewisham study

Council feasibility study covers route optimisation between SELCHP and Goldsmiths, network expansion, technical design and delivery options.

02 · A study, not a network

It is a study, not a built network, so we do not assume any Lewisham block is connected to it.

03 · Lewisham Gateway

A progress report describes a 1,500 square metre energy centre with district heating; Get Living is named as manager of its build-to-rent homes.

04 · Convoys Wharf

Deptford scheme granted planning permission for up to 3,500 homes in April 2014.

If your block has a communal heating system, HIUs, FCUs or MVHR, we can quote for servicing it. Send us the O&M manual or the plant schedule and we will scope the contract against it.

Lewisham Property Maintenance FAQ

Yes. Heat interface units (HIUs) in flats on communal heating systems should be serviced annually. A visit covers plate heat exchanger descaling, strainer cleaning, valve checks and controls calibration, with a written, photographed report for each flat. Mainteniq holds SAV Advanced HIU Service Engineer certification (PERS-30839). If your block is connected to a communal or district system, send us the plant details and we will quote.

Lewisham Council's selective licensing scheme came into effect on 1 July 2024 and covers around 20,000 privately rented properties, though Telegraph Hill ward and a small area of Blackheath are excluded. Properties let to three or more people forming two or more households need a separate HMO licence. Whether your property is covered depends on its address and how it is let, so check the council's licensing pages. Mainteniq can arrange the gas, electrical and PAT certificates that licensing typically relies on.

SELCHP, the energy recovery facility near New Cross Gate, is operated by Veolia, which supplies heat from it to Southwark Council estates in Bermondsey. Lewisham Council has published a feasibility study for a heat network taking heat from SELCHP to buildings in the north of the borough, but that is a study rather than a built network. Some Lewisham developments, such as Lewisham Gateway, have their own energy centre with district heating. If your block has communal heating, we can quote for servicing the HIUs and plant.

Yes. We price blocks per unit, credit the survey against year one, and make no charge for flats where we cannot gain access. Managing agents and RTM or RMC directors get one contract, one schedule and a written, photographed report after every visit, so there is a clear record for each flat.

Yes. We run a 24/7 emergency line with a same-day response target, and contract clients get priority. Typical call-outs are no heating, no hot water and air conditioning failures. All gas work is carried out by Gas Safe registered engineers.
