AVOID at ALL COSTS


AVOID at ALL COSTS

TERRIBLE CUSTOMER SERVICE.

I have even written to the CEO who I believe is Mr Terry Lee Nash for help but no response.

3 MISSED APPOINTMENTS with NO explanation or apology.
2 LATE APPOINTMENTS one so late I could not wait after 4 hour delay. I ADVISED GRM.
FIRST visit bathroom extractor VENTED DIRECTLY into LOFT INSULATION - THEREFORE USELESS.

NEXT VISIT bathroom extractor left NOT WORKING.
Extractors to bathroom and downstair WC NOT VENTED CORRECTLY.
I'VE WAITED 6 weeks for corrective work. I'm being fobbed off by being told that "installers" are very busy.

EVEN the company inspecting GRM's work were amazed at the TERRIBLE QUALITY of the extractor installations.

GRM often DO NOT ANSWER THEIR PHONES and TODAY IS ONE OF THOSE DAYS.

This company has ruined my home they have lied and now left my home in a state of damage and destruction
The flooring is ruined, the rooms are full of plaster as well as the appliances, the electrical fixtures have been damaged and now don’t have heating in my home pics show the damage , I have been told not to turn the central heating on in case of a fire hazard, contacted them and now a week later haven’t replied to my concerns, I’m disabled and now over Xmas cannot live in my own home due to industrial waste left for me to clear , the garden is a bomb site and all the rooms have rubbish left on the floor , the appliances that I said they can use have been damaged with most having to be thrown but on contact with the contractors they lied saying all waste would be collected but now have blocked my calls.
The company was made known of these problems and was to contact me last week but have chosen to ignore my calls , this is the worse company I have ever known they should be stuck off from offering energy services, the legal side will start in the new year, unfortunately I have to stay with friends until this is resolved through the courts as with the pictures you can see the damage they have caused as well as the stress it has coursed me .
Avoid at all cost they are cowboys

We had an air source heating install done by GRM Energy, the team was professional, hard working and very approachable throughout the install. I have been contacted twice by GRM energy since to confirm that all is working as should.
I would have no hesitation in recommending GRM Energy for any install you may require.
