Avoid Glow Green. They installed a boiler October 2017. Gas engineer not tidy. Didn't put things back and there was a small water leak from the pipe which he did fix some days later. At least it worked though. Our main problem was with the annual service of the boiler which in their glossy brochure made out the aftercare was so good and they would ring us to book a service each year, so we didn't have to worry. What a joke. It has been nothing but worry and they put the price up each year on our monthly direct debit. Each annual service has been a series of me having to book a service. They never phoned us and we have been constantly let down on dates with them not turning up and weeks later finally getting someone. This last one we had just had enough. Was told Andy would ring us to sort out our direct debit cancellation. Well hadn't heard from him the next day and decided to cancel direct debit our end. We did get a phonecall from Andy on the Monday 21st December 2020 saying he could see we had cancelled our direct debit . He sounded very sympathetic and said of course he would reimburse us for the unfulfilled service last year. Well it never happened. Everything has gone silent from Glow Green. It is now 23rd January 2020 and we have still not been reimbursed.bi sent a letter to Andy reminding him of his promise on 21st December to reimburse us. Nothing. Silence from him. We have since had a local gas engineer service our boiler. Very reliable and efficient. As long as you have boiler serviced annually with a gas safety registered engineer then Worcester Bosch will honour the warranty. You don't need to stay with Glow Green for the warranty to count. In fact we had Worcester Bosch out recently free of charge. Prompt and efficient. PLease avoid Glow Green Ltd. Nothing but stress with that company. Julia C by
