AVOID WARMZILLA FOR BOILER SERVICING. YOU HAVE BEEN WARNED.
I took out a contract with Warmzilla for boiler cover - servicing and repair. I was told I had to wait 2 weeks before my annual boiler service could be done. So, that was fine and understandable. So after 2 weeks I contacted Warmzilla to arrange the boiler service. A date - a Monday - was fixed but the engineer phoned up at nearly 5pm that day to say he could not make it and he would contact me later to get another appointment later that week. By 4pm that Friday NO CALL from the engineer. So I contacted Warmzilla direct. They made lots of excuses basically saying that they employ contractors to do the servicing and repair work, have little control over which jobs such contractors prioritise and contractors would obviously prioritise more lucrative boiler breakdown work. Anyhow I was promised that a new date would be arranged. BUT NO SUCH DATE WAS ARRANGED even a month later. I therefore cancelled the contract. AVOID WARMZILLA FOR BOILER SERVICING!
UPFATE: OK. So a few minutes after my review went live I received a personal phone call from the Operations Director (and also one of the company's founders) of Warmzilla apologising for the service I had received. He also said that the information about contractors deprioritising service work was incorrect and he would follow up internally with the staff members concerned and look at customer service training. He did accept, however, that my experience is true and was a failure in this instance. So. I am grateful the Ops Director himself followed this up and it shows they obviously do care about service. But I cannot deny whst my experience was.

Very poor service on all levels.
Failed to turn up for 3 different half day appointments. No notification that this may happen on each occasion. I had to chase up on each occasion. Boiler cabinet left dirty - grubby fingers all over white paint and not put back in place correctly. Wedges of what looks like thick card used to hold in place. Screws not utilised. No comment from service engineer to say it was an issue. No paperwork left or any notification to say it would be emailed. Very unsatisfactory. Unfortunately can't give 0 stars or would have. Customer service very good at saying they're sorry.

Josh made this rather complicated experience seem so smooth. He ensured I was kept up to date at all times and communicate with great understanding and timely responses. Juggling between myself, state agent and tenant. 10/10 service Thank you Josh.
