Heating Maintenance for Concierge-Managed Buildings
How RARE supports concierge teams, building managers and managing agents across London's prime residential buildings.
London's luxury residential buildings — the concierge-serviced developments of Knightsbridge, Mayfair, Marylebone and St John's Wood — operate to a standard where heating failure is not a minor inconvenience. It is a crisis. Residents expect the same standard of warmth, hot water and climate control that they would receive in a five-star hotel. When that standard slips, the concierge team is the first to hear about it.
RARE's relationship with concierge-managed buildings is built on one principle: we make the concierge team's job easier. That means responding when called, explaining clearly what is wrong and what we are doing about it, arriving presentably, working cleanly, and providing documentation that building management can rely on. This guide explains the specific demands of maintaining heating in these buildings and how we meet them.
How communal heating works in luxury residential buildings
Most purpose-built luxury residential buildings constructed in the last twenty years use a communal heat network rather than individual boilers per flat. Understanding this system is essential for concierge teams who need to communicate with both residents and engineers when faults occur.
Central Plant Room
One or more commercial boilers — often cascade-configured for redundancy — heat a primary circuit that runs throughout the building. These boilers are serviced by the managing agent's heating contractor (ideally RARE).
Distribution Circuit
Insulated pipes run from the plant room to each floor and apartment. The primary circuit delivers heat at a high flow temperature (typically 70–80°C) and returns cooled water back to the boilers.
Heat Interface Unit (HIU)
Each apartment has an HIU — a compact unit that transfers heat from the primary circuit to the apartment's own heating and hot water circuits. It also measures the apartment's heat consumption for billing. HIUs require annual servicing.
Apartment-Level System
From the HIU, a conventional heating circuit serves radiators or underfloor heating throughout the flat. If this circuit develops a fault, it is the resident's (or leaseholder's) responsibility — not the building management's.
What concierge teams need from their heating contractor
We have worked with enough concierge teams to understand that the requirements go well beyond technical competence. These are the non-negotiable expectations:
- Consistent, named engineers — familiar faces who know the building and can be trusted in front of residents
- Clear communication about arrival times, duration and what was found
- Presentable appearance and respectful conduct in communal areas and apartments
- Clean working practices — dust sheets, shoe covers and full clear-up after every visit
- Same-day emergency response for plant room failures affecting multiple residents
- Advance notification of planned works that may require building management coordination
- Prompt, clear documentation issued within 24 hours of each visit
Emergency response: what happens when heating fails?
In a building where fifty apartments share a single heat source, a plant room failure is a building-wide emergency. Having an engineer on-site within hours — and having them know the building — is the difference between a resolved incident and a full management escalation.

Planned maintenance schedule for concierge buildings
A well-run concierge building runs on schedules. We build our maintenance programme around yours — fitting visits into the building's calendar with minimum disruption to residents.
Full plant room service — boiler combustion analysis, heat exchanger inspection, pump and valve servicing, expansion vessel check, water quality testing, safety relief valve function test. Gas Safety Certificate (CP12) issued.
Magnetic filter inspection and clean on plant room and all HIU units. System pressure check across all distribution circuits.
Visual inspection of plant room — pressure gauge readings, leakage checks, condensate drain condition, flue terminal inspection.
Condensate pipe lagging check, system pressure top-up, controls calibration for heating season. Boiler ramping test under full load.

Frequently Asked Questions
What is the typical heating system in a concierge-managed London building?+
Most purpose-built luxury residential buildings in London use a communal heat network — a central plant room with one or more commercial boilers feeding heat interface units (HIUs) in each apartment. Some older or converted buildings have individual boilers per flat. The concierge or building manager is usually the first point of contact for any heating fault.
Who is responsible for maintaining the communal heating in a concierge building?+
The freeholder or managing agent is responsible for the communal plant room and heat network. Residents are typically responsible for their own HIU unit and any radiators or underfloor heating within their apartment.
How quickly can RARE respond to a heating failure in a concierge building?+
For our PPM contract clients, we target a four-hour response for emergency call-outs. We are familiar with the entry procedures, plant room locations and system layouts for properties we maintain — which significantly reduces diagnosis time when faults do occur.
Can RARE provide out-of-hours support for concierge teams?+
Yes. Our engineers are available 24/7, 365 days a year. For concierge teams managing high-value residential buildings, we provide a direct emergency line and named engineer contacts so calls are answered promptly and professionally.
What documentation does RARE provide after a service visit?+
A full written service report including gas safety certificate (CP12), combustion analysis results, component condition notes, water quality readings, and any recommended follow-up works. This documentation is issued digitally and stored in our client records.
