// WE PROVIDE PROFESSIONAL AIR SOURCE HEAT PUMP
INSTALLATION N LONDON, DELIVERING EFFICIENT, LOW-CARBON HEATING SOLUTIONS FOR RESIDENTIAL PROPERTIES AND LARGER BUILDINGS. HEAT PUMPS ARE INCREASINGLY SELECTED AS A MODERN ALTERNATIVE TO GAS HEATING, OFFERING LONG-TERM ENERGY SAVINGS, REDUCED CARBON EMISSIONS AND RELIABLE PERFORMANCE WHEN SYSTEMS ARE CORRECTLY DESIGNED AND INSTALLED.

// DUE TO THE WIDE VARIETY OF PROPERTY TYPES ACROSS LONDON — FROM HOUSES AND APARTMENTS TO MULTI-STOREY BUILDINGS AND BLOCKS OF FLATS — SELECTING THE CORRECT HEAT PUMP SYSTEM IS CRITICAL. NOT EVERY SYSTEM IS SUITABLE FOR EVERY BUILDING, WHICH IS WHY PROFESSIONAL ASSESSMENT AND SYSTEM DESIGN ARE ESSENTIAL.

WHAT IS A HEAT PUMP?

MODERN AIR SOURCE HEAT PUMPS ARE DESIGNED TO OPERATE EFFICIENTLY EVEN IN LOWER OUTDOOR TEMPERATURES, PROVIDED THE SYSTEM IS PROPERLY SIZED AND MATCHED TO THE BUILDING

HOW DOES A HEAT PUMP HEAT A PROPERTY?

Heat pumps operate most efficiently with low-temperature heating systems, delivering steady heat over longer periods rather than short, high-temperature bursts. This approach improves comfort and reduces overall energy consumption.

HEAT PUMPS CAN BE INTEGRATED WITH:

  • underfloor heating systems
  • low-temperature radiators
  • appropriately sized hot water cylinders
 

Overall performance depends on system design, not just the heat pump unit itself

WHICH HEAT PUMP SYSTEM

IS RIGHT FOR MY BUILDING?

Choosing the correct heat pump system depends on several factors, including:

  • building height and layout
  • available external and internal space
  • heat demand and usage patterns
  • pipe run lengths and vertical distances
 
 

IN LONDON, THESE CONSIDERATIONS ARE PARTICULARLY IMPORTANT
DUE TO SPACE CONSTRAINTS AND BUILDING COMPLEXITY. THE TWO MAIN AIR SOURCE HEAT PUMP CONFIGURATIONS ARE MONOBLOCK SYSTEMS AND SPLIT SYSTEMS

Outdoor air source heat pump installations

1/ MONOBLOCK
HEAT PUMP SYSTEMS

Monoblock systems contain all refrigerant components within a single outdoor unit. Heated water is then distributed into the property.

MONOBLOCK SYSTEMS ARE TYPICALLY SUITABLE FOR:

  • houses and townhouses
  • bungalows
  • low-rise residential buildings
  • properties with short pipe runs
 

While effective in the right conditions, monoblock systems have limitations in taller or more complex buildings.

2/ SPLIT
HEAT PUMP SYSTEMS

Split heat pump systems separate the outdoor unit from the indoor unit and are connected by refrigerant pipework. These systems must be installed by F-Gas Registered Engineers.

SPLIT SYSTEMS ARE OFTEN THE PREFERRED SOLUTION FOR:

  • apartments and duplex flats
  • multi-storey buildings
  • blocks of flats
  • buildings with internal plant rooms
  • installations with long pipe runs or significant
    vertical distances
 

In many London properties, split systems allow installations that monoblock systems cannot accommodate due to physical or technical constraints.

THE CORRECT SYSTEM CHOICE DEPENDS ENTIRELY ON THE SPECIFIC BUILDING AND INSTALLATION CONDITIONS

CAN A HEAT PUMP WORK IN A BLOCK OF FLATS OR LARGER BUILDING?

YES — WITH THE CORRECT DESIGN APPROACH

HEAT PUMPS CAN BE SUCCESSFULLY INSTALLED IN:

  • small and medium blocks of flats
  • larger residential buildings
  • mixed-use developments

SUCH PROJECTS REQUIRE:

  • accurate heat-loss calculations
  • careful load management
  • appropriate system configuration
  • correct selection between monoblock and split systems

 

Heat pump installations in larger buildings must be treated as engineering-led projects rather than standard domestic replacements.

BOILER UPGRADE SCHEME (BUS) –
GOVERNMENT GRANT UP TO £7,500

The UK Government’s Boiler Upgrade Scheme (BUS) provides a grant of up to £7,500 to support the installation of air source heat pumps in eligible properties

The scheme is designed to encourage the transition from fossil fuel heating systems to low-carbon technologies. Eligibility depends on the existing heating system, property type and compliance with technical requirements under the scheme.

Our heat pump installations are designed to meet BUS technical criteria, and we provide support throughout the grant application process, helping clients navigate eligibility and documentation requirements. The grant is applied directly to the installation cost, reducing the upfront investment required.

IMPORTANT CONSIDERATIONS

BEFORE INSTALLING A HEAT PUMP

A HEAT PUMP IS NOT A DIRECT REPLACEMENT FOR A BOILER WITHOUT ASSESSMENT. FACTORS SUCH AS INSULATION LEVELS, RADIATOR SIZING
AND HOT WATER DEMAND MUST BE REVIEWED TO ENSURE SYSTEM EFFICIENCY AND COMFORT

PROFESSIONAL SYSTEM DESIGN IS ESSENTIAL TO ACHIEVE RELIABLE PERFORMANCE AND LONG-TERM VALUE.
