If you are considering a Worcester, choose carefully and check the specs.

24i + 28i Juniors have no control over hot water temperature.

The numbers on most of the range relate to the Hot Water output. So a 30Si will give approx 30KW of hot water, but only 25KW of heating.

Same with CDI. A 37CDI will give approx 37KW of hot water, but only 30KW of heating. Don't get caught out.

If you have a high hot water demand go for the CDI range, they have a better hot water delivery rate than SI range.

I like Worcesters, they are easy to install, telescopic flues as standard and a good range of plug in programmers.

If you find an Accredited Installer you can have the warranty extended to 5 years.

Ask about though, I mainly install Worcesters, not had a great deal of experience installing other brands. Ferg says good things about Remeha boilers, but can't comment as I've never dealt with them.

A friend of mine had a very bad experience with WB Technical. The childish know-it-all attitude had to be heard to be believed. They hung up on him in the end when he attempted to get some information that obviously wasn't on their 'help screen'.....

I've not had an experience like that, but at times it seems they are just reading off the screens and have no knowledge of boilers at all.

Thats if you can get through to them at all.
