  • Photographed report every visit

Mainteniq provides planned maintenance contracts, HVAC maintenance, HIU servicing, 24/7 emergency HVAC and heating repair and compliance certificates across Southwark for managing agents, landlords, residential blocks and commercial sites. Southwark is fifteen minutes from our Westminster base, so planned visits and emergency call-outs are covered by our same-day response target, and every visit ends with a photographed report. We work on the riverside developments of Bankside and Elephant and Castle, council and housing association estates, and the offices of London Bridge.

Council landlord

Southwark is one of London's largest council landlords. Much of its estate stock is heated by district and communal networks, including systems linked to the SELCHP plant in Bermondsey.

Active regeneration

Elephant & Castle and the Old Kent Road Opportunity Area are among the most active regeneration zones in inner London, delivering BTR towers with FCU air conditioning, MVHR and BMS controls.

Three kinds of work

Add Bankside and Borough's commercial quarter and the Victorian terraces of Peckham and Camberwell. We cover communal plant, new-build systems and landlord compliance under planned contracts.

Communal heat networks & SELCHP

A large share of Southwark's homes are heated by communal and district networks rather than individual boilers, with parts supplied by the SELCHP energy-from-waste facility in Bermondsey.

01 · In each home

Heat interface units (HIUs) in each dwelling.

02 · Plant room

Heat exchangers, circulating pumps and pressurisation units.

03 · Network

Network controls on shared infrastructure carry the maintenance burden.

04 · Resident impact

Poorly maintained HIUs are a common cause of hot water and heating complaints, and of avoidable energy loss.

Mainteniq provides planned HIU servicing, plant-room maintenance and network fault-finding for estates, blocks and managing agents across the borough.
