High quality work, minor communication issues

The work was done to a very high standard, and everyone involved was friendly, professional, and kept us informed throughout. We experienced some communication issues where information about the works requested had not always been conveyed to the guys on the ground who were actually doing the work, which led to some back and forth and frustration. But overall a really great result - our house is notably cosier and has a more stable temperature throughout.

I had an excellent experience with Optama from start to finish. The whole process was incredibly well organised, and they were very accommodating when arranging a convenient installation date.

The indoor heat pump installation in my flat was completed to a very high standard — everything was carried out professionally, efficiently, and with great attention to detail. I’ve already started to see a noticeable reduction in my energy bills, which is fantastic.

All of the workmen and engineers were friendly, knowledgeable, and went above and beyond to help. The support both before and after the installation has been outstanding, and the office staff were equally impressive — always quick to respond and extremely helpful with any queries.

I wouldn’t hesitate to recommend Optama to anyone considering a heat pump installation — a truly 5-star service.

If you don’t qualify for a grant don’t expect them to tell you.

Laura from Optima sent out a surveyor they said we might be entitled to government grant. Surveyor was lovely. He was in our house for over 1 hour. He said he would let Optama know his findings and they would be in touch. Laura rang to say they would be in touch to discuss. We were told by the surveyor to expect an energy report at the very least. The company never got back to me to advise if we were getting the grant. I can only assume after several attempts to contact them that we weren’t accepted for grant. We didn’t meet the criteria. That’s 5 months now.

Well done OPTAMA

From my initial meeting with Karen and subsequent discussions with Linda, Lorna,Gillian,Cheryl,and Leigh they were very professional in dealing with all the applications that was required for my installation.
The installation team were very skillful in their workmanship and dealt with any problems that occurred.
From first meeting to complete installation took less than two months to complete .
Well done team OPTAMA.

Cannot praise this company and their workers enough. Efficient , on time, kept us informed about how the job was progressing. There was no slacking . They all worked very hard. They tidied up after themselves worked around us and were good with our pets . All the old heating equipment was taken away. Of course it was a bit chaotic as it was a big job but optama made the whole process as smooth as it could be.

Would recommend

Friendly service from start to finish.
No hard sell, which I hate! Michael was very helpful, even before I had decided to go with Optama.
Had cavity wall and loft insulation installed, both extraction and installation teams kept me informed and cleaned up after themselves.
Air source heat pump team were great, installed radiators where I wanted them, and were very efficient!
Waiting for solar panels now!

Optama carried out full installation with great communication

Optama carried out full installations to my property through Eco4 funding.
Air source heat pump, radiators, bedrooms and loft insulation, wall extractor fans /venting and Solar Panels in the garden after I had completed the initial preparation ground work.
All work carried out was expertly done to a high standard, the workforce involved were friendly and respectful to the property with minimal disruption.
All work was completed within five working days, one after the other they came and seemed to be in touch with each other as to when to start their particular trade of work.
Needless to say all unused materials and rubbish was removed from the property.
Octama kept me informed throughout the process with excellent communication, I was never left wondering.
All questions and enquiries were quickly answered and gave me the utmost confidence in the Eco4 installation.
In my opinion staff at Octama and the tradesmen themselves are a credit to the company. Many Thanks

Easy, upfront, communicative. Recommend

They made the entire process easy, they were upfront and communicative. The work was done well and quickly, they were great even after the work was done. They cared about even the little things and sent someone out to check the house for any snags at the end and make sure we were happy.
At one stage we had a few teams working in the house at the same time. there was a small incident but it was resolved and fixed up and we are really happy with the work. the house is like night and day since the heating was changed and the insulation completed. the control system is really easy to use too.
A year later I needed to get back in touch and customer service still very friendly and helpful. Id recommend this company especially with the horror stories that I have heard and even witnessed myself.

Energy efficiency improvements - sorted

Optama handled my application for funding to improve my homes energy efficiency. They also managed the installation process, which involved solar panels & storage heaters. There were a couple of minor issues during installation - but these were rectified within a few days.

A week to install air source and boiler

The installation of the air source & boiler was done in a week, there was a lot of moving belongings about, lots of people coming and going, lots of big holes being drilled in walls, then new pipes to connect the new radiators but not thankfully under the floors or though the walls, a fair amount of mess but the guys cleared it up when they left, they had sticky plastic that covered the floors and carpets and stairs, so no mess left behind. The air source unit is huge and sits under the bathroom window, so not massively noticeable from inside, from outside you cant miss it, but hey ho overall its an improvement on the oil tank!! It can be noisy, the first few nights it seemed like the entire house was humming, then via the app the unit if now off from midnight to 8am, the noise is less noticeable though the day. The boiler takes up a lot more space vertically than the old oil boiler did and is not contained in a neat box like the old boiler, we've no idea how to conceal it, so find a spot in your house where the boiler and all the components inc the labyrinth of copper pipes, expansion cylinders and insulation can be hidden, you will appreciate that in the long run. Our boiler is in the lobby, we are still working out the best way to hide it!! Other than that everything was fine and dandy, the guys polite and courteous. One point to bear in mind, if you have wrought iron radiators like we did, and the guys need to take them out, get someone else to help with that task. They weight a ton and its not fair on their backs, having to lug from upstairs to outside. Once we realised how much they weighted the guys had already lugged them :( so just a tip to offer and give them a hand.

I am hugely grateful to Optama for the installation of radiators and solar panels to my house, also having my loft insulation updated, and all on Government funding, initially I thought it was too good to be true but I was wrong!
There was a certain amount of uncertainty regarding the starting date but when the tradesmen arrived they were quick and efficient, and did a brilliant clean up job of all the mess involved in removing old storage heaters and installing new ones, along with 3 extractorfans. The solar panel installation and connecting was straightforward with no inconvenience and the loft insulation was the same.
All in all I consider myself very fortunate to have had these improvements to my house which I wouldn't have been able to afford myself.
