Local to Blackheath
Blackheath is one of the areas we cover most often for air conditioning. From the Village and the streets around the heath to Blackheath Park and the Cator Estate, we survey and install for homeowners across SE3.
Homes here tend to be high-value and carefully kept, so the finish matters as much as the cooling. We plan pipework and unit positions at the free survey, then send a fixed-price written quote within 24 hours.
Blackheath's housing ranges from Georgian and Regency terraces and large Victorian villas to the mid-century Span houses of the Cator Estate. Parts of the area are conservation areas, so the look of outdoor units and external pipework needs particular thought.
Tall ceilings and big sash windows make period rooms feel airy, but upper floors still get very warm in summer. Ducted or carefully placed wall units, with pipework hidden wherever the building allows, suit these homes best.

Most enquiries we get from Blackheath fall into a handful of categories: discreet ac for period and conservation-area homes; multi-split systems for several bedrooms; boilers with unvented cylinders for larger houses; heat pump surveys with heat-loss calculations. Whichever applies to you, the starting point is the same. We look at the actual house, not a floor plan or a photo, and recommend what will work in those rooms.
For Blackheath (SE3) homes we install three types of domestic system. A single-split pairs one indoor unit with one outdoor unit and suits a single bedroom, office or loft room. A multi-split runs several indoor units from one outdoor unit, so you get separate control in each room without a row of units on the outside wall. A ducted system hides the indoor unit in a loft or ceiling void and delivers air through discreet grilles, which suits renovations and homes where visible units aren't wanted.
We install Mitsubishi Heavy Industries, Mitsubishi Electric, Daikin, Fujitsu and Haier. GHS is F-Gas registered as a company and our engineers are personally F-Gas qualified, so refrigerant work is carried out and commissioned correctly. Installation starts from £1,500 with zero VAT until 31 March 2027, servicing from £150 + VAT, and AC repairs are £180 + VAT for the first hour, then £75 + VAT per additional half-hour.
We're approved installers for Baxi, Vaillant and Worcester Bosch, with Vaillant our preferred brand and manufacturer warranties of up to 10 years depending on the model. In Blackheath we replace old boilers, convert open-vented systems to combi boilers, fit system boilers with unvented cylinders for larger homes and install smart thermostats such as Hive.
Boiler installation starts from £1,600 + VAT and servicing from £95 + VAT. Heating repairs are £120 + VAT for the first hour, then £50 + VAT per additional half-hour. We're Gas Safe registered (552913) and hold ACS, G3 unvented hot water and Water Regulations qualifications.
A heat pump only performs well when it's designed around the house. That's why every heat pump enquiry from Blackheath starts with a survey for £250 + VAT, including heat-loss calculations and an assessment of radiators, hot water demand and where the outdoor unit and cylinder can go. We're approved installers for Baxi and Vaillant and hold heat pump installation and design certifications. Servicing starts from £220 + VAT and diagnostics are £180 + VAT for the first hour.
GHS is not directly MCS certified. We can arrange installations through an MCS umbrella scheme where applicable, so eligible customers can access the Boiler Upgrade Scheme grant.
Alongside Blackheath, we regularly work in Greenwich, Eltham, Dulwich, Welling. From our base in Eltham, SE9, Blackheath is part of our core South East London and North West Kent coverage for boilers, servicing, air conditioning and heat pumps.
Before the survey, it helps to note which rooms get too hot or too cold, how old your current boiler is, and whether you have any plans for extensions or loft work. If you live in a flat or a conservation area in Blackheath, check whether you need permission from a freeholder or the council for external equipment. We'll talk through positions with you so you have what you need.
Every installation is quoted at a fixed price, and parts, materials and additional works are set out where applicable, so the figure you agree is the figure you pay. We accept bank transfer, card and cash, with a 50% deposit on installations and the remaining 50% on completion.
Reviews
“I recently had air conditioning units installed in three rooms at my property by Greenwich Heating Solutions Limited, and I am extremely pleased with the service provided from start to finish. The planning and advice throughout the project were excellent. The team took the time to assess the property and made valuable recommendations regarding the most suitable units for each room. Their expertise was particularly evident in the routing of the pipework and trunking, ensuring the installation was both practical and aesthetically pleasing. The workmanship was completed to a very high standard, with great attention to detail and a professional approach throughout. The installation was carried out efficiently, the work areas were left clean and tidy, and the finished result exceeded my expectations. I would highly recommend Greenwich Heating Solutions Limited to anyone considering air conditioning installation. Their knowledge, professionalism, and quality of work have been outstanding, and I am delighted with the end result.”
“Josh and his father fitted an air conditioning unit for me, they worked efficiently and were very tidy. Both very polite and professional. Would highly recommend.”
“Josh installed my aircon unit. Very efficient, turned up on time and left the room clean and tidy. Would definitely recommend and would not hesitate to use again.”

Local issues
Building age, property type and hotter summers all shape what Blackheath homes need. Across Greenwich & Lewisham, these are the issues we see most.
In conservation areas, where the outdoor unit goes matters. We look at rear elevations, flat roofs and screened positions first.
Big period houses can mean long runs from room to outdoor unit. Planning them properly keeps performance and appearance right.
Top-floor bedrooms in tall houses trap heat. Multi-split systems let each room be controlled separately.
Large homes with several bathrooms often need a system boiler and unvented cylinder rather than a combi. Our G3 qualification covers unvented cylinders.
UK summers are getting hotter, and demand for air conditioning installers peaks as soon as a heatwave arrives. Booking your Blackheath survey in spring means the work is done before the next hot spell. For boilers, the same logic applies to winter: replacing an ageing boiler before the cold weather avoids a breakdown when you need heating most.
