Proximus Energy Solutions Arvostelua 

Really happy with my new boiler installation. The service was professional from start to finish, everything was completed to a high standard and the engineer was friendly, reliable, and left everything clean and tidy. I would definitely recommend to anyone looking for a new boiler. Thank you again! ☺️

Polite, punctual, and left the place spotless- top marks.

Battery and solar combo means we barely touch the grid anymore.

Working with proximus was easy and trouble free. I got the system I needed and all of the advice anyone could need. Highly recommended!

I travel to Cyprus regularly which inspired me to have solar panels. The team that fitted mine were exceptional from start to finish. The workmanship was really good. And they were all professional and polite. I've had no problems and yes can see the savings already. Thanx guys I will definitely recommend you

Projects details were easy to understand.

Service information was clearly organized.

Provided a good service. The work was excellent. I’d definitely recommend this company for solar panel installation.

I am sharing my honest experience as the homeowner following an ECO4 heating installation carried out by Proximus Solutions Limited (trading as HeatZen) at my property in March 2026.
While a Worcester Bosch combi boiler was installed, the process resulted in severe technical defects, property damage, and missing legal paperwork. After independent audits by Tecnika and Simply Certification validated 11 official Non-Conformances on site, Proximus Director called me directly to offer a personal apology. He assured me he would take personal oversight of my case, act as my single point of contact, and personally follow up to ensure every physical, cosmetic, and technical issue was resolved to my satisfaction.
Unfortunately, those assurances were not kept:
Incomplete Technical Remedies: During a remedial visit in July, engineers successfully relocated the boiler flue vertically through the roof (resolving an initial issue where it was routed through a child's wardrobe). However, they failed to fix severe hydraulic shock (water hammer) across my pipework or properly commission/demonstrate the radiator controls.
Unfulfilled Promises & Abandoned Contact: Following the visit, I emailed Director Ateeb Mehmood detailed updates outlining what remained outstanding, including promised professional carpet cleaning for stains left by installers and repair of plaster/brickwork damage. Despite his explicit commitment to personally manage my case and call me back, he never contacted me again and ignored my correspondence.
Missing Statutory Safety Certificates: Months after the installation and flue alteration, Proximus has still failed to provide or register mandatory compliance paperwork, leaving me without a Gas Safe Register Certificate, Electrical Minor Works Certificate, Building Regulations Compliance Certificate, or Benchmark warranty sign-off.
Breached Scheme Deadlines: Proximus completely ignored the mandatory compliance deadline of 16th July set by their certification body (Simply Certification), despite my written confirmation offering full access and cooperation to complete the repairs.
On 24th July 2026, Simply Certification formally closed their complaint file as unresolved due to Proximus’s default, handing the case over to the Dispute Resolution Ombudsman (DRO).
I acted in complete good faith throughout, but being abandoned by senior management after clear promises leaves me no choice but to pursue resolution via the Ombudsman, the Gas Safe Register, and my Insurance Backed Guarantee provider.

We recently had a new boiler fitted by this company and have found them very reliable. The installer arrived on time and was very efficient from start to finish, he even took away all the rubbish. It’s lovely to have instant hot water again. Would recommend.

I had my Tesla battery and solar panels installed by Proximus, and the whole experience was excellent from start to finish. The installation was handled professionally, and I have been genuinely surprised by how much I am already saving on my electricity bills. We have a large house and an EV charger, so energy costs were a real concern for us.

I would happily recommend Proximus to anyone considering solar installation or battery storage. Great service and a very positive experience overall.
