What our clients say
Loft conversion
ACE Group fitted air conditioning in our loft bedroom in Brentwood. During the heatwave it was a lifesaver. You can barely hear the unit running at night, and the engineers were polite, tidy, and finished cleanly in a single day.
Mark & Sarah H.Brentwood • Loft ConversionGarden office
Having a split system in my garden studio in Leigh-on-Sea changed how I work. It cools down within minutes in July and keeps the room warm in winter without running the main heating. Really neat pipework with zero mess left behind.
Emma ThompsonLeigh-on-Sea • Garden OfficeHealthcare clinic
Finding a local firm that could install our clinic's air conditioning and sign off the electrical feeds without hiring separate contractors was fantastic. Completed right on schedule with zero disruption to patient appointments.

One local team for cooling, heating and electrics, from the first survey to the final sign-off.
Yes. We conduct a full in-person technical survey at your domestic or commercial premises at zero cost and with no obligation. We assess room dimensions, heat loads, electrical connection requirements, and pipework routes before issuing a fixed-price written quotation valid for 30 days.
We install high-efficiency wall-mounted splits, ceiling cassettes, ducted concealed units, and multi-split systems for commercial premises, offices, retail spaces, and homes. All systems are modern air-to-air heat pumps that provide both powerful summer cooling and economical winter heating.
A standard single-room split installation is typically completed in 1 day. Multi-room domestic or small commercial systems generally take 2 to 3 days. For commercial premises, we offer out-of-hours and weekend installations to eliminate disruption to your staff and customers.
Yes. Modern split systems are air-to-air heat pumps, so the same unit that cools a room in summer can heat it efficiently in winter.
Modern wall-mounted units are very quiet, with many running at around 19 dB on their lowest setting. We recommend units suited to bedrooms and quiet spaces during your survey.
Often you won’t, but it depends on your property, for example if it’s listed or in a conservation area, and on where the outdoor unit goes. We’ll talk this through during your survey.
A like-for-like boiler swap is usually completed in a day. Moving the boiler or changing the system type takes longer, and we’ll give you a clear timescale with your quote.
It depends on the size of your home, how many bathrooms you have, your water pressure and how much hot water you use at once. We look at all of this during your free survey before recommending a boiler.
Combi boilers suit most smaller homes and save space; system boilers suit homes that need hot water in several places at once. We’ll explain the options for your home.
Yes. We fit and set up modern thermostats and controls so your heating runs when you need it.
Replacing an old, inefficient boiler with a modern condensing model usually wastes less fuel, which can bring your bills down. How much you save depends on your home and how you use your heating.
Yes. Annual servicing keeps your boiler running safely and efficiently, and most manufacturers require it to keep the warranty valid.
An Electrical Installation Condition Report checks the condition and safety of a property’s fixed wiring, including the consumer unit, circuits, sockets and lighting, and lists anything that needs attention.
Landlords in England must have the electrics in rented homes inspected at least every five years. Homeowners are generally advised to have a check about every ten years, and when moving into a property.
Yes. We install home and workplace EV chargers on a dedicated circuit and set them up ready to use.
