From enquiry to handover in St Albans
Heat loss survey
We assess fabric, glazing and ventilation to size for winter as well as summer.
Design
Units are chosen for their heating output at low outdoor temperatures, not just their cooling rating.
Install
Outdoor units go where defrost water can drain safely and air flow is not restricted. We keep work areas in St Albans screened and tidy at the end of each day.
Set controls
Schedules and set-backs are configured so the system heats efficiently.
Points to plan for in St Albans
Defrost water
Outdoor units shed water and ice when they defrost. They need a drained position away from walkways.
Leased premises
If your St Albans premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Winter output
Heating output falls as it gets colder outside, so we size against winter design temperatures.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Typical premises in St Albans
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Which postcodes do you cover in St Albans?
All of them, including AL1 and AL3. Give us your postcode when you enquire and we will confirm the visit details.
Is it cheaper than electric heaters?
In most cases, yes. A heat pump delivers several kWh of heat per kWh of electricity, while panel heaters deliver one. Actual savings depend on the system, building and tariff.
Do outdoor units ice up?
They frost in cold, damp weather and run short defrost cycles automatically. Drainage is planned so the water does not freeze on a path.
