Sussex Air Conditioning & Heat Pumps installs MCS-accredited air source heat pumps for homes and businesses across East and West Sussex, from Lewes and Burgess Hill to Uckfield and the Sussex coast. A heat pump takes heat from the outside air and uses it to power your central heating and hot water, typically producing 3–5kW of heat for every 1kW of electricity used – a highly efficient, low-carbon alternative to a gas or oil boiler.

How much does heat pump installation cost?

Costs vary depending on property size, current heating system, and the size of heat pump required, but most domestic installations are eligible for government support through the Boiler Upgrade Scheme (BUS), which currently offers up to £7,500 towards the cost of an air source heat pump. We’ll confirm your exact eligibility and give you a clear, itemised quote before any work begins with no hidden costs.

I’ve had the pleasure of working with this team to get an MVHR extractor fan unit fixed in one of my properties, and I couldn’t be happier with their service. They always communicate promptly, are honest, and deliver high-quality work. Special thanks to Serena for her exceptional support throughout the process. The team offers excellent value for specialist work, and I will definitely work with them again in the future. Highly recommended!

I usually avoid writing reviews, but this experience has been so consistently bad across two separate jobs that it needs to be said.

Between myself and a friend, we have dealt with the same pattern of behavior from this company. In both cases, the work was overpriced, unprofessional, and in the end, not even completed properly.

In my situation, they came out three separate times and still failed to fix the issue, yet tried to charge over £2600 for a repair that another engineer completed in a single visit for £1300. To make matters worse, the engineer acted as if he was doing me a favor by offering a “special price”, when in reality it was still well over what was reasonable. He also spent a lot of time criticizing other companies, claiming he gets so much work because of their incompetence.

My friend’s experience was equally unacceptable. They hired the company to install air conditioning, only to be overcharged and supplied with second-hand, faulty parts. After the job was supposedly finished, the property smells of cigarettes. Completely unprofessional and disrespectful.

Across both jobs, the themes are the same:
• Overcharging and pressure tactics
• Failing to fix the actual problem
• Unprofessional behavior and bad-mouthing competitors
• Poor workmanship and careless mess left behind
• Questionable record-keeping and excuses when challenged

Several people in the local trade have since mentioned that the business has gone downhill recently, which matches our experiences.

This review will remain because other customers deserve to know the risk before spending their money. I genuinely wish I didn’t have to write this, but when people are being let down, overcharged, and spoken to disrespectfully — especially vulnerable or elderly customers — it needs to be said.

I strongly recommend looking elsewhere.

I hired Sussex Air Con to install some air conditioning in my 81-year-old mother's home. Not only did they take advantage of her and overcharge, but they used second-hand, faulty parts. After the work was completed (if you could call it finished), muddy footprints were left throughout the property, and cigarette ends and cans of Red Bull were littered all over the garden.

After speaking to a friend who works for another local maintenance company, it seems that in recent months the company has fallen apart. DO NOT USE!

I used to have a contract with Daikin for my Air Source Heat Pump and their service was terrible. I switched to Sussex Air Conditioning & Heat Pumps a couple of years ago and they have been amazing. Great customer service, very responsive, and they seem to know the heating system much better than the Daikin team did. I can't recommend them highly enough.

Excellent company. I first contacted them some 6 months ago regarding an air-to-air heat pump for my Grandpa annex. Paul came and surveyed and gave much useful advice. Positioning of the exterior unit was tricky, and had to be changed several times.

For one reason or another I wasn't able to go ahead until towards the end of April, but once I pushed the start button, it all happened rapidly and competently, and now I have a truly fine system, rapid and economical, which heats when it's cold and cools when it's hot.

These guys know what they are doing.

We recently used Sussex Air Conditioning and Heat Pumps Limited to install a split system with two air conditioning units for our home.
The initial contact and quote was quick and efficient and the price quoted was as expected with no surprises.
Administration back up was quick and efficient throughout the process and any changes to our original plans were agreed quickly.
The installation was carried out by Paul and Leo. Paul consulted us throughout the process and they both worked hard to complete the job well within the suggested time frame. Everything was tidied up as they went along and how it all worked was explained to us clearly prior to them leaving.
Many thanks to the team at Sussex Air Conditioning and heat pumps I am very happy to recommend you to all of my friends and family.
