Where we work around Blackheath
Blackheath sits within London's dense commercial fabric: shopfronts, offices above, studios and venues, where outdoor unit positions and access need careful planning.
That includes premises in B65, CO2, GU4, IP19 and SE3 and the surrounding districts. We also work in nearby Greenwich, Catford and Eltham. In Blackheath, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
Included as standard
- Condition survey of the existing system
- Refrigerant recovery with waste transfer documentation
- Removal and disposal of old equipment
- Installation of new efficient units

What to think about in Blackheath
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Access and parking
Town-centre jobs in Blackheath often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Typical premises in Blackheath
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
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.

Do you also cover Greenwich, Catford and Eltham?
Yes. Alongside Blackheath, we also cover Greenwich, Catford and Eltham. Each has its own page with local guide prices.
Which postcodes do you cover in Blackheath?
All of them, including B65, CO2, GU4 and IP19. Give us your postcode when you enquire and we will confirm the visit details.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
Should we replace R410A systems now?
Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.
