Reliable and professional heat pump installers
We chose Assembly Renewables for the installation of a heat pump at our home. They have been great throughout.
They were very open and transparent from the start of the process, giving a realistic quote, taking the time to explain every section and answering all our questions.
The installation process was quick, so the heat pump was already working by the day two.
There were a couple of teething issues, as could be expected. Both times, Assembly Renewables were quick to solve them and follow up to make sure they had been taken care of to our satisfaction.
Overall, we are very happy we chose them to install the heat pump. They offered the right balance of price, attention to detail and professionalism that we would be unlikely to get with a bigger company or a small local provider.

Can't recommend AR highly enough
Can't recommend Assembly Renewables highly enough.
The whole world of eco-energy options was new to us but having looked at a few options fairly superficially, I'm very glad we went for AR. They couldn't have been more helpful and friendly. The process was straightforward, as was the installation a few weeks later. Everything was explained and done in such a way that we didn't feel like complete morons(!).
Everything has been working well and efficiently since.

Excellent Teamwork on Double Heat Pump Installation
Team turned up promptly on agreed start date and installed two systems - one in the main house the other in the granny annex. The installation was completed within 6 days with my wife and I in residence with minimal interuption of cooking and heating facilities. The two heat pumps were installed obove head height at the back of the house preserving the usable patio area. The installation of the pressure vessels in the loft and removal of header tanks has doubled my loft storage area although the installation of the larger main tanks on the first floor has taken away the airing cupboard shelf above the old hot water tanks. Slight dissapointment at losing my power showers but the loss of pressure has been more or less restored by installing mains pressure shower heads, still perfectly usable and more economical on water usage, which is good.
Need to do a bit of decorating where the gas boilers have been removed but overall we are well pleased with the professional service and installation - thanks for a great job well done.

Professional through out
What can i say assembly renewables from start to finish were fantasic,they went through everything with me, first of all sending a surveyor to go through what he is doing, and then send a second suveyor out, this i found was of great use.
They have just not left me to do the paper work on my own, they have been there at all times and sent every thing off to make life easy for me, the quality of there work was lmpeccable so clean at all times, through out my experince with this company all of the staff have been there for me.
I would highly recommend this company to family and friends

Assembly Renewables responded really well to our needs
Assembly Renewables responded really well to our initial concerns about the Heat Pump location. They also turned up on the agreed days (which is more than can be said for others). The quality of the work was great and the result was a exceptionally warm house and hot water. Slight concern on behalf of the workers for the late hours they ended up doing. That was the only minor gripe
Stress free experience
Excellent service by a helpful and knowledgeable team. Heat pump and solar installations are working perfectly, will recommend to friends and family
Things couldn’t have been better!
From first contact to fitting the heat pump the experience couldn’t have been better. Assembly Renewables handled everything, the energy certificate and Government grant included. The team who fitted it were very pleasant and efficient and left everything clean and tidy.

Air source heat pump made easy
Air source heat pump made easy. Assembly renewables made the whole process easy, including managing the £7500 grant. The surveyors were great and the contractors who put in the system were brilliant. Very happy to recommend Assembly Renewables - in fact I already have and my neighbour is now following suit but with solar panel installation

An Honest & Caring Service
After much deliberation and having had the opportunity to discuss with three different air source heat pump companies, I decided to go ahead with Heat Pump installation in my property by Assembly Renewables for their honesty and their intention to address the needs of the customers. The previous companies could not provide the assurance I was looking for in keeping my house warm at the height of winter as there is a high energy loss in my property. So far, it has worked well and has met my expectations, although we are not yet in the thickest of the winter. The Engineers were experts in their own field and completed the work with due diligence and on time. There was timely and active support from the management of the company all the time. I have been so impressed with their service that I have asked for further expansion of solar panel installation to meet my electricity energy needs in the future.

They understand customer service!
We reached out to Assembly Renewables last summer and following a conversation with the sales team, we agreed that they would install an air source heat pump for us. They were courteous, efficient, and pleasant throughout. The admin/support team back at the office responded promptly to our queries, and the installations manager responded outside normal hours when we had a hiccup with the system in the early days. So now we are considering the installation of a battery to optimise our solar panels, obviously we have contacted Assembly Renewables again. This is a company that understands what customer service - including after-sales service - actually means, and delivers!

Really good professional service from start to finish, couple of minor issues that were sorted quickly.
The pump is very quiet and heats very well.
No issues in recommending.
Excellent customer service and expertise
Assembly Renewables supplied and fitted both solar panels and a heat pump for me. Their customer service and expertise at all stages of the process was excellent - making them stand out from other companies quoting for me. The installation was quick, clean and the fitters were professional and helpful. The 60 day check up was reassuring and very helpful - including guidance on making the most of different electricity supply tariffs in my particular situation. I would certainly recommend based on a very positive personal experience!
