Heat-pump design, installation and aftercare across Scotland
Heat pumps designed for your building.
Thinking about a heat pump? A free FLO survey checks your current heating, hot water and heat loss to see what your property can support. If a heat pump fits, we design and install the complete system.

Plan a larger project
More than an outdoor unit
The whole heating system has to work together.
A heat pump can only deliver the comfort and efficiency its design allows. FLO checks each room, the emitter sizes, hot-water demand, pipework, electrical supply, outdoor position and controls before the system is fixed in writing.
Quoted as one complete system
The unit, cylinder, emitters, pipework, controls and electrical work are considered together.
Set up for everyday use
Commissioning, controls guidance and aftercare are part of the route—not an afterthought.
FLO project photography
Designed around real buildings—not a catalogue page.
Every installation has different space, access, appearance and system requirements. These photographs from FLO’s own project library show why the position and surrounding system matter.
Rural and off-gas properties
Cold-weather duty, exposure, fuel replacement and service access all influence the design.
Heat and electricity planned together
A heat pump changes electrical demand; solar, batteries and supply capacity should be considered early.
Positioned for performance and access
Airflow, sound, drainage, pipe routes and future maintenance determine a sensible position.
Your FLO assessment and quote
What will FLO include in your heat-pump assessment and quote?
FLO assesses the property first, explains what we recommend and puts the proposed system, installation work, price, exclusions and aftercare in writing.
Request a free heat-pump surveyYour heating needs, room by room
FLO records the calculated heat loss for each room, the design temperature and how the proposed heat pump is sized.
Everything included in the installation
Your quote lists the heat pump, cylinder, radiator or underfloor-heating changes, pipework, controls and electrical work.
Where the equipment will go
You see the outdoor position, indoor equipment, pipe and cable routes, access needs, likely disruption and expected programme.
Handover, warranties and support
FLO sets out commissioning, controls guidance, certificates, warranties, servicing and who to contact after installation.

Air source heat-pump installation
Start with a free property survey. FLO checks your heating, designs the complete air source heat-pump system and explains the installation and quote before you decide.

Planned checks for an existing system, with findings separated from repairs or design changes that need further work.

Technical assessment for workplaces, estates and community buildings where load, continuity and distribution need deeper planning.

Review schedules, weather compensation, hot-water priority and user overrides against comfort and energy evidence.

Clear answers before you enquire.
Do heat pumps work in Scottish winters?+
Yes, when the system is sized for the building's design conditions and commissioned correctly. Output and efficiency at colder temperatures must be part of the design.
Will every radiator need replaced?+
Not automatically. A room-by-room assessment shows which emitters are adequate and where a larger radiator or other change is justified.
Can a heat pump work in an older building?+
Age alone is not the deciding factor. Heat loss, airtightness, available emitter area, pipework and the occupants' comfort pattern determine the right approach.
