I've found that myself. Some limited sector data on Yahoo but but it is fragmentary or dead. For US there are the SPDR sector ETFs and for Europe the Stoxx 600 sector ETFs. But for the UK there is little, I can't find an EFT for each sector.

Why do you uses ETF ? In PRT you can work directly on the original Stoxx Europe 600 sector indices.

Also note: the Stoxx Europe 600 Sectors are in fact equivalent of the ICB-"Supersector" level (19 supersectors). In ProRealTime you can also find the Stoxx Europe TM indices for the ICB-Sectors (41 Sectors IIRC), which gives you a better insight.

Here are the codes if you want to have a look in PRT (in each line, the first number is the ICB-sectorization, the last code is the mnemo of the corresponding Stoxx Europe TM indice):

Do you know where one can get the FTSE sub-sector charts?

For example Mining is good but the five sub-sectors (Coal, Diamonds & Gemstones, General Mining, Gold Mining, Platinum & Precious Metals) would be better.
