Lack of response from an initial enquiry

I recently enquired about a battery storage system and a week later I'm waiting for someone to reply. I've had to send a complaint to the CEO regarding this, but this is not a very good initial view of Instagroup as it indicates how they are likely to conduct business with you, the customer, later down the line.

Thank you for your feedback, we’re really sorry for the delay you experienced.

This isn’t the level of service we aim to provide. We’ve recently identified a system issue that unfortunately meant your enquiry wasn’t processed as it should have been, which is why you didn’t receive a timely response.

We completely understand how frustrating this must have been, especially as a first impression, and we appreciate you taking the time to raise it.

We’d really like to put this right, if you’re open to it, please send us a direct message with your details or contact us at sales@instagroup.co.uk and we’ll ensure your enquiry is picked up as a priority.

Thanks again for bringing this to our attention.

I recently had my boiler serviced and my hot water tank relocated, and the installers were fantastic. They were friendly, hardworking, and offered great advice on how to reduce my energy bills. I’m now looking into adding solar and battery storage as my next step. Thanks, InstaGroup!

loft insulation work

Recently had some loft insulation installed by insta group.
Very pleased with the whole process. Was contacted very quickly after my initial inquiry by Jack Gibson-Barton in the office to talk through what was needed and the survey was booked for a few days later. Surveyor was on time very helpful and explained the work that was needed and took me through the costs etc.
Actual installation was done last week and again installer turned up on time, went through the work that was to be undertaken and then shared photos of the completed work.
Would recommend.

The installation was very rushed and slapdash

The installation was very rushed and overall pretty slapdash. Also left quite a lot of bits of insulation on the stairs/landings for us to hoover up afterwards, and pick up from the street outside the house. Ultimately very expensive for what it was, but part funded by a rebate. Even with that, it left me wishing I’d just done it myself.

Excellent trustworthy company

We cannot fault this company from the survey, solar panel installation to battery commission. Everyone we dealt with was polite, efficient and knowledgeable. Even the scaffolders were careful of all our plants. The director Ed Andrews ensured everything ran smoothly and was available for any concerns; we felt in safe hands. We honestly cannot rate them highly enough, excellent company.

Loft and external wall insulation

InstaGroup insulated the our loft and applied external wall insulation for us. The whole process from the survey to completion is well organised and professional. Highly recommended company.

Misdiagnosed the problem

Misdiagnosed the problem. Said it was condensation and it turned out to be the cavity wall insulation. Don't accept any responsibility.

Dear Ms Clausin

As we are the material supplier, but have not carried out the installation, we have discussed the issues you are experiencing with CIGA (Cavity Insulation Guarantee Agency) and have been advised they will respond directly to you with a resolution.

Best regards

Excellent customer service

I found the customer service of InstaGroup just excellent. I needed my loft insulated however I was battling to get a leak in my roof fixed by my management company for almost a year which meant that I had to reschedule the insulation a number of times. Instagroup did this without any hesitation and were incredibly kind and understanting. The quality of the work is also really good and overall I couldn't be more happy.

Loft Insulation Installed

The booking process was friendly, easy and efficient. The installers arrived when they said they would and the installation has been done to a good standard.
The first day only consisted of only 3 hours as they had insufficient materials. I would have expected something to be put down on the stairs to protect the carpet and the mess was not cleaned up but told "you might want to run a hoover round". The job was completed on the second day although one of the installers was looking at his phone a lot of the time even when engaging with me.
Overall not unhappy with the work but Interpersonal skills could have been better and the teams should be sent out with a hoover.

Cavity wall insulation

Cavity wall insulation
Very good quick install of bonded beads. Clean and tidy work.
The only minor thing is that they didn’t email the information in advance or send reminder but otherwise great.

Great job - Solar panels on my bungalow.

I am 90 years old and Insta have just installed Solar panels on my bungalow.
I cannot speak highly enough of the people on site and how polite and efficient they were.
All installed and up and running in the same day with a minimum of fuss and no mess.
Thankyou
