I just had installed first time central heating. I wanted to acknowledge personal who went above and beyond to make all this happen. Carbon team - Callum, Jemma and Kathryn were really helpful and did everything so I had installation done before my holiday. Installation team- Ross and Aron, very tidy, clean, and fast working everything was done in two days time.
For now we are just using a hot water and will add my review after the heating starts.
For now everything is perfect.

We contacted this firm about solar panels for our property.
They have made two appointments, both of which we waited in for, but to no avail as no one bothered to turn up.
We phoned and were told someone would contact us, again this did not happen.
The representative then texted and promised he would come today at 1pm and again did not turn up, even though we had his word on it that he would definitely be here.
To say we are disappointed is an understatement, and unclear how firms can operate in this manner, so my advice would be to look for a company that does turn up as this one certainly does not either turn up or apologise to its customers

Just had 1st time central heating and new boiler fitted . Plumbers were great and did there utmost to remedy any problems . Also fitted system in 2 days with a minimum of mess . Great job , only downside was the fitting of insulation not carried out in area that was told would be carried out in .

8 months arranging free boiler and central heating system, 23 telephone calls, 23 Lies.
All staff even Managers at this Company are 100% unprofessional.
WARNING DO NOT USE Carbon Saving Group.
unless you want a massive headache from individuals who have no respect for running a business correctly.
I have reported this company to Trading Standards and the correct authorities.

it took you 8 months of bad dicisions to eventually find out the property was a listed building And you can't do listed buildings, you not only gave me a massive headache You also gave the tenants in the property a hell of a bad time.
It finally went to your Manager who promised me she would get another company who can do the work for you. The manager has ignored my calls and is just as useless as the rest of the people who work for you....
Your Just full of broken promises and very poor quality in everything you did
Rubbish

We have scored you Average, because we feel that despite having no choice in the matter of having Gas Central Heating or not, the best we could of hoped for was a system that would be easy to use, where we could set our own settings without issues,!!. However since it's been installed, we have had on-going problems with the Thermostat control, we have tried it on Auto, we have tried it on Manual, but the heating comes on for a while but then switches off, & does not stay on for the time we want it too. The Hot water, is either boiling hot, or just over hand hot, if we go too high the boiler makes pressure noises, if we go too low, we have luke warm water & cold radiators,
Also some of the cladding has since come unstuck in places, the joints are not even, we still feel the boiler is too big, we have seen other boilers installed for our neighbours, they seem to have much better set ups then us,
Sorry if this is not what you expected but, you asked us to be honest.

A few issues not related to the boiler but to the installation are still not cleared up. Mess left at the end of the day

The survey could be improved but Covid may have created some problems. 2 Days install was carried out by a knowledgeable experienced and efficient team. Impressed. 7 Radiators and 24kw Ideal Boiler. Requested a Nest as I use Android, however, you should be aware that the unit does not come with a cable so a bit difficult if you pay for installation it cannot be connected. As it was the Electrician had an old cable in his Vehicle so as he can program and install it. Have had only the use of heating for 6 weeks. As water is a scarce commodity, thought should be given to how it runs around the house, especially in the kitchen, as it takes an age to obtain hot water which wastes more water than normal and so you need to keep your dishes, etc until you have a pile. As regards morning shaves if you need hot water - use a kettle.

I contacted them to ask about cavity wall insulation under the Government's Green Homes Grant. After a phone conversation I ended up getting cavity wall insulation, a massive increase in loft insulation, underfloor insulation and a new boiler too under the Energy Company Obligation grants. I had to contribute a few hundred pounds but massively less than the work would have cost and we not only felt the benefit over the Winter, but the house is cooler now. The work was done quickly and efficiently once funding was in place. The only issue we had was that the surveyor did not spot that the boiler flue was not legal and exited the house over a neighbours boundary so there was a delay in getting a roof modification to move the flue. Overall though, thoroughly recommended

Thank you to the two guys that removed my old boiler and replaced it with a modern boiler during such difficult time (COVID) . They were excellent. Please pass my best regards to them.

Very good service we now have heating, They were clean & tidy & made a really good job.
I have recommended them to several people one has had his fitted and one is ongoing.

My review is mixed. My dealings with the group, the fitters and the customer service team were good. They were friendly and helpful and if the review was solely down to that then I would rate more highly but it became apparent over a year later, during a service, that the filter I had paid for to protect my central heating and water system had not been installed. When I contacted customer services they apologised and sent out an engineer to fit one. Having payed for the extended warranty, which the filter was a requirement of, it leaves me worried about any harm caused and the longevity of the system.

Excellent from start to finish the crew who fitted the central heating were superb many thanks 😊

Excellent company to deal with, good communication, easy to get hold of, very efficient at organising and getting the work done on time.
Would certainly recommend them.

Staff excellent from 1st contact. very helpful over phone . Always polite, patient and treat you as an individual.
The installation team very helpful over phone, and on site the staff were friendly and informative. I left them to it, with confidence they would complete the job to a high standard, which they did. My experience has been nothing but positive, than you all for your professionalism.

My experience with Carbon Saving Group from the start was excellent. The people in the office were helpful and polite and made everything clear and understandable. The chap who came to survey the property was also very good and explained everything. Later when the two young men did the underfloor insulation were excellent and did a job which I would not like to do with cheerfulness and care and treated me with respect. Finally the plumber who fixed the new boiler worked hard and did the work efficiently and was very polite and considerate. I could not fault them and neither would I want to. Thank you Carbon Saving Group.
