Good experience, at last

Engineer turned up on time, diagnosed the problem quickly and fitted the necessary new parts quickly. Nice guy. Pity he could not have been scheduled a couple of months ago!

Great service.

After a major repair to our boiler a small drip developed under the boiler. Glowworm made a fast appointment and Sam arrived, quickly diagnosed the fault and replaced the original, cracked plastic pipe.

Combi Boiler installed not even 18…

Combi Boiler installed not even 18 months ago and has worked fine until 2 weeks ago when the hot water started to run cold after 10 minutes or so (not ideal when running a bath). After a few days we could no longer get hot water for more than 2 minutes at a time so a bath was no longer possible and washing up etc. isn't exactly easy. Called Glow Worm Warranty and the engineer turned up the next day (rang beforehand which was really handy) diagnosed it as flow sensors and said he would be back in a couple of days when the parts arrived. 10 days since reporting the fault we still have a faulty boiler and still apparently they are waiting for parts. I have a 6 month old baby and a 5 year old son which has meant relying on friends and family on the use of their baths to wash our children. Terrible customer service and means I won't be installing another Glow Worm boiler in my lifetime!

Leaking Glow worm boiler

My boiler started leaking on Christmas day! I managed to arrange a repair visit on the 29th. #620, Brent called 10 mins before his arrival which is always really useful and it gave me a few minutes to walk my dog back home. Many tradesmen/companies don't realise how useful this pre visit call is. Brent had the patience to listen to my details of the symptoms and was quick to find the faults. He took the time to explain the faults, how the components worked and how he would repair them. He was friendly and highly professional, a credit to Glow worm/Vaillant.

Prompt service. No charge as simple issue within boiler that caused no risk or safety issue. Just an annoying click. But resolved quickly

Efficient but noisy

Had a Climapro2 RF boiler installed. It seems to work well but is SO noisy, emitting repeated loud buzzing noises, usually in pairs on a regular basis. These can be heard in adjoining rooms.

#604 engineer Paul visited today for warranty work on boiler. Paul is a credit to the company, very professional and great communication. I called yesterday regarding some boiler issues and it was repaired this morning under warranty. Customer service has been amazing.

Had a glow worm compact 24c combi…

Had a glow worm compact 24c combi boiler fitted less than 3 years ago. Had nothing but problems with it right from the start. Customer Services was also rubbish the last time it had a fault. My landlord, a gas engineer and myself all read the manual and identified the same fault (which should have come under warranty), but Customer service tried to make out that fault code didn't exist! It's in the manual for that model. Problem was eventually fixed. Now it has developed yet another fault (f28...so something wrong with ignition so won't even fire up! So once again, no heating or hot water for someone who is disabled and has a health condition that is made worse by cold conditions and stress! And during an extreme cold weather warning!). If you are thinking about getting one of these, don't! You would do better to making something similar from a tin can and garden hose and fart into it occasionally.
