Mainteniq provides planned maintenance contracts, HVAC maintenance, HIU servicing, 24/7 emergency HVAC and heating repair and compliance certificates across Kensington and Chelsea for managing agents, landlords, residential blocks and commercial sites. Kensington and Chelsea is ten 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 high-value flats and townhouse conversions, portered mansion blocks and the managing agents that run them across Knightsbridge, South Kensington, Chelsea and Notting Hill.

Council heat networks

Major estates at Chelsea Creek, Worlds End and Notting Dale. Leaseholders maintain their flat-level HIU while the council operates the communal energy centre.

Premium rentals

Knightsbridge and Belgravia properties at the premium end of the rental market need PPM covering VRV/VRF multi-zone air conditioning, smart home systems and underfloor heating.

Stucco conversions

The dominant stock in Chelsea, South Kensington and Notting Hill. With 44% of dwellings privately rented, CP12 and EICR demand is consistent.

RBKC's 32 council-managed heat networks

RBKC manages 32 communal heating and hot water networks, one of the highest concentrations of council-operated district heating in London.

01 · Range

From small blocks with a shared boiler plant to the Notting Dale Heat Network and Worlds End Estate.

02 · Responsibility

The flat-level HIU is the leaseholder's or assured tenant's, not the council's.

03 · Why service

Annual maintenance protects flow rates, hot water performance and heating efficiency.

04 · Upgrades

RBKC has been consulting leaseholders on infrastructure upgrades.

In the meantime, proactive HIU maintenance is the most effective way to avoid disruption. We provide written service reports suitable for lease compliance purposes.

Kensington & Chelsea Property Maintenance FAQ

On RBKC's communal heat networks, the heat interface unit (HIU) inside each individual flat is the responsibility of the leaseholder or assured tenant, not the Royal Borough. The communal energy centre and primary pipework are RBKC's responsibility. This means leaseholders must arrange and pay for annual HIU maintenance themselves. Mainteniq provides annual HIU servicing with a written service report, which is typically required for lease compliance purposes.

Yes. Mainteniq provides planned maintenance contracts for high-specification residential properties in Knightsbridge, Chelsea, and Belgravia, covering Daikin and Mitsubishi VRV/VRF multi-zone air conditioning, underfloor heating, smart home systems (Lutron, Crestron, KNX), and BMS integration. Work is co-ordinated with building managers or estate agents as required.

RBKC landlords with gas appliances must hold a valid Gas Safety Certificate (CP12), renewed annually by a Gas Safe registered engineer. All private rented properties require an EICR every 5 years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. PAT testing is required for furnished rental properties. Mainteniq co-ordinates all three under a single maintenance contract.

Yes. RBKC has numerous conservation areas covering much of Chelsea, Kensington, and Notting Hill. External works affecting the character of a conservation area require planning permission. This affects external condenser unit siting for air conditioning, new flue routes for boiler replacements, and any external building penetrations. Mainteniq advises on compliant installation approaches and works within Listed Building Consent requirements where applicable.
