Warm GB air source heat pump

After using GB Solar for my solar panels and battery storage and had an excellent experience there, I turned to Warmgb to upgrade my heating system. To put it simply WOW.
As with GB Solar, Warm gb were brilliant to deal with. Nothing was too much trouble. I found new radiators on line and Andy dealt with them directly and arranged for delivery when the work started. Andy also chased them up when brackets were missing. The two guys Adam and Matt who fitted the new air source heat pump, radiators hot water cylinder and pipes were first class. Polite, knowledgeable kept everything tidy very professional.
They worked really late one evening to get the system up and running. Everybody involved has pride in their work.
Now the system is up and running the heating system is fantastic. Every room is warm and comfortable. All can be monitored on an app of course, but we have the thermostat in the living room set at 19• 24hours and it just works.

Based on my experience this is the way forward. I would highly recommend Warm GB

Outstanding, fully recommend WarmGB

WarmGB, and notably Andy, have proven what excellent customer service and quality mean. We was renovating a house and approached WarmGB and other companies over installing an ASHP as we was unsure on the relatively new tech. Andy by far was the standout person, using his vast experience, he described, understood and gave us options that even with many of my silly questions even answered outside of his working day. The price was the most competitive and time to start was quick. Installation done within the week by his friendly team, we did need a couple of minor tweaks to suit our lifestyle habits after which Andy helped us sort out. We are really pleased we went with WarmGB and with our ASHP, the house is always warm and in the year we have had it, noticed our heating price go down to. Next on the list is solar panels! Couldnt fault Andy and WarmGB, and we fully recommend this great local company.

Warmgb have recently fitted a heat pump…

Warmgb have recently fitted a heat pump for us.. We have to say the whole experience was extremely positive.. From day one we found Andy and the team very professional and respectful of us and our property. Nothing was too much trouble. As I was unsure of the benefits of this type of heating system Andy spent time, over and above, explaining how everything worked, his depth of knowledge reassured me that we would be warm and have enough hot water..
Since completing the work the Warmgb team have stayed in contact and have visited several times to answer our queries and to help us to run our system as efficiently as possible.
We definitely feel confident going into winter that we are going to be warm and cosy.. following our positive experiences I feel able to recommend Warmgb to our friends.. Thank you

Extremely knowledgeable and helpful.

Extremely knowledgeable and helpful.
We are toasty warm with loads of hot water.
We have had an air source heat pump fitted with solar panels and battery storage.
The whole thing seems to be working well and actual electricity provided by the grid is down to a minimum.
It is early days but so far we are very pleased.
The team are very helpful in terms of advising and guiding us through the process of understanding and operating the system.
Even for us oldies.

I had a Warm GB heat pump and GB Solar…

I had a Warm GB heat pump and GB Solar installation in November 2024.
For an " oldie" the understanding of the process and technology took some getting to grips with but the team made it all very easy and I am now reaping the reward of living in a super toasty house that in the summer months is costing nothing to run!
There were the inevitable teething problems in integrating the new system to an older system but these were all dealt with immediately and professionally.
I would recommend the Warm GB and GB Solar combination to everyone.

Excellent Heat Pump Installation

Having used Warm GB’s sister company GB Solar for battery storage, we got Andy in to design a heat pump system for us! Andy was thorough and incredibly knowledgeable about how he would maximise efficiency of the system. I naturally did a lot of research regarding heat pumps as there has been a lot of negative press towards them but what I learned was that the most important thing about heat pumps is the person who designs your heating system, bespoke to your home. Andy has done a cracking job and so far after a month of use I have a cop of 4.5 on the hot water which is the hard part so I am expecting some excellent results come winter when we use the heating side of it.

After sales service has been great too which is where a company really earns its reputation, I was abroad for much of the installation and when I came back, Andy came back and walked with me to see if there was any issues, I pointed out a couple of minor issues and they were immediately rectified.

I would wholeheartedly recommend WarmGB for your heat pump!

Hi Brett,
Wow—thank you so much for taking the time to share your experience! We’re delighted to hear that, after working with our sister company GB Solar, you chose to trust WarmGB and Andy with your heat pump system.
Andy will be thrilled to hear your feedback. He puts a lot of thought into creating efficient, bespoke systems, and it's fantastic to see that reflected in your results—a COP of 4.5 on your hot water is excellent! Your deep dive into heat pumps really paid off, and you’re absolutely right: good design tailored to the home is key.
We’re also really glad to know that even with you being abroad during the install, our team’s support and communication made everything smooth. Aftercare is just as important to us as the install itself, so thank you for recognising that.

Vaillant heat pump system install

from start to finish they were very informative and professional guiding us through the entire installation. warmgb completed all the bus paperwork for us. during the installation the work was carried out to a very high standard and the guys were very respectful of our property. even after the works were completed Warmgb still kept in touch to make sure we were happy with the system, even remote monitoring how the system ran to make sure it was functioning as efficiently as possible. so over all a fantastic experience.
