Fischer  Reviews 

From the first consultation right through to the installation the service they provide is second to none, professional, courteous and a friendly team, would highly recommend them.

From the outset we were kept informed of appointment times, install dates and times, snagging dates and times and feedback conversations. Fisher really do let you know what's going on and they do stick to their word. In most areas today customer service is a thing of the past, not with Fisher. We were particularly impressed with Danny in customer service. I mentioned snagging, I am being very picky, they sent a man on a 4 hour round trip to put an end stop on a pipe that had been missed, he was with us for 10 mins, that is service.
The actual heating system is excellent, all rads individually controlled and near instant heat. The hot water system heats water as you need it and at good pressure, better than before. So far I can't fault the company or the product

Quick & efficient installation. Team were professional, polite and friendly. Removed my old radiator, fixings and cleaned up afterwards. Great service

I purchased a water heater from this company around three years ago, and unfortunately the experience has been disappointing from the start.

The installation was problematic, including the heater being dropped during fitting. This resulted in several follow-up visits before the installation issues were finally resolved. I withheld payment until the work was completed properly, which eventually happened.

Three years later, the water heater has now failed. I understand that equipment can develop faults, which is exactly why warranties exist. The issue is not that the heater has broken; it is the difficulty in obtaining support under the warranty.

My property has been without hot water for weeks. Multiple engineer appointments have been arranged, but engineers have failed to attend as scheduled. I have used all of my annual leave booking time off work for appointments that never happened. When I could no longer take additional leave, I reasonably requested a weekend appointment, given the circumstances, but was told this was not possible.

To summarise: the installation was problematic, and now when the product has failed within the warranty period, I am struggling to get the fault repaired. If your water heater breaks down, be aware that support may require you to repeatedly take time off work, and weekend appointments may not be available.

I would welcome a response from the company and, more importantly, a resolution to the ongoing issue so that my household can finally have hot water restored.

Update: after repeatedly expressing I am unable to take anymore time off work to resolve this in a weekday (I have taken 2 days off already) and requesting a weekend visit, I have been offered another weekday appointment as a 'resolution'. I have been told the engineers are based in Scotland and won't drive to Cumbria to assist. I have also been told that the fault which is likely to be the timer won't be covered by a warranty and I will be charged. Apparently the timer is not essential so I suggest not having one installed in the first place (we were unaware this is an option).

We were very happy with the people who came to do the work in our home, very polite and friendly. Worked very hard.
We did have a few teething problems, we contacted Fischer, and Danny was in touch with us within the hour.
His help has been outstanding, can’t fault the customer service. Thank you

Delighted with the rep who was very professional and knowledgeable and ensured I was buying the right product for my needs. The fitting of the boiler was also excellent, a full explanation to all my questions was given. Very tidy job. I am extremely pleased with my new boiler and the Service I received.

Friendly service

Heaters look lovely. Tried them and they are very easy to use and operate. Installers were bang on time, very friendly. Completed the work much quicker than I expected. Left everything clean, neat and tidy. Would highly recommend

Friendly, efficient engineers, who left my home clean and tidy.

Installers professional, quick, neat and tidy. Radiators good in looks and quality. Explained usage as well as handing over the necessary booklets.
Excellent customer service from telephone call follow up by Daniel. He listened to my queries and explained simply and in detail to my total satisfaction. He talked me through while I USED the controls which was helpful (being an elderly lady).
I felt Daniel went beyond his duty to be sure I was satisfied I could control my new radiators and I could see and hear when they were working.

Fast and simple service, people were kind and followed me through the whole process.

On 26May2026 Fischer Future Heat came to install 2 separate systems in our bungalow:
(1) Replacing our immersion heater with an Aquafficient water heater. This involved disconnecting our Eddi solar energy diverter, removing the hot water pump, and connecting the mains cold water system to the new water heater. We're pleased to report that the installation was a success, although we did need to make some adjustments to the timings to prevent the heater from taking electricity around midnight, when we only wanted it to heat while our solar panels and batteries were charged. The installers gave a strong impression that they knew exactly what they were doing.
(2) Replacing the thermostats of our 13 existing Fischer electric radiators with Wifi-connected thermostats. This installation is still not fully active, as the Tydom Wifi associations only worked for 11 out of 13 thermostats, as the bungalow's Wifi network relies on Wifi extenders. Unfortunately, the installers gave a strong impression that they didn't know exactly what they were doing, so I will need to discuss the association of the thermostats with the Tydom manufacturer Delta Dore Technical Support.

We had also hoped that the 3 rusting electric heaters would be replaced, but we have since spoken to Fischer Customer Services, who have rules that, even though the heaters are still in their 10-year guarantee period (from late 2017), rusting is not covered.
* Rusting was apparently due to "wear and tear", even though it only occurred on the 3 heaters in "bathroom" (possibly damper) settings.
* They could be treated to remove the rust, but that will impact that guarantee.
* We believe all the heaters are manufactured using mild steel, which is susceptible to rusting, even though these 3 heaters were installed in a bathroom, shower room and WC/cloakroom, where rust-resistant stainless steel would have been a much better choice.

Having had Fischer electric heaters since 2017, we would be reluctant to recommend them:
* They do rust, even though the sales team say they don't.
* We were forced into replacing our old gas boiler, and, due to new safety regulations, could not install a new boiler in the same place. The Fischer heaters, while more convenient, have proved to be more expensive to run than the replaced gas central heating, and were also not cheap to buy!

We would, however, recommend the Aquafficient water heater, especially after 8+ years without hot water from our gas central heating. The Eddi solar energy diverter could be used to divert solar energy to the immersion heater, but not efficiently during the winter.

Very tidy competent fitters, very clear instructions and advice. To date all dealings punctual and professional

From the sales and contract staff to the engineers who attended site a friendly and professional service.

Great customer service , Danny rang me back after a mix up with my mobile no and was very helpful in explaining a question I had .

Men who installed the boiler polite helpful explained how it operates when it was installed

The fitter arrived early was pleasant and polite, got on with the job , could tell he was experienced and knew what he was doing. Cleaned up when finished, explained how it operates.

Despite problems the work was carried out to a high standard, everything explained and left clean and tidy.

On the whole i was satisfied with Fischer heat.
I had 2 heater and water heat heater installed which was done in a professional way leaving the site clean and tidy.
I was not informed why the recommended products was best for me. I think that the products are expensive comprepared with local companies .
