Rated 4 out of 5 by from Perfect for an old boiler! Fitted to my 30 year old Baxi back boiler in just a few minutes. Works perfectly and had all the bits needed. I don't know if it will last as long as the old one but it was so inexpensive who cares?

Rated 5 out of 5 by from Excellent bit of kit! Have replaced boiler thermocouple atew times before but this time got replacement from Screwfix - a good move!. It comes with all the fittings you could want and is easy to fit so had the boiler back up and working in a few minutes. The click anď collect in 5 mins is a great feature. Very satisfied with this item and service. Would recommend to anyone.

Rated 5 out of 5 by from Easy Fit Thermocouple Been using these for some years now, good quality, great value and very easy to fit. To be on the safe side I usually change ours every two years, but the old ones clean up like new so I believe they would last much longer. I had to remove a small circlip from around the old thermocouple and use it on the new one since one isn’t provided with the standard kit, so the super might be a better buy for some if these extra fittings are needed.
