Sorry Guys - I'm not an EWI guy....... see if someone else can advise who is good where.
Weber - Flitwick, Bedfordshire
SAS - Exeter, Devon
Alumasc - St Helens
(all do good courses, from the other post.....)
Other system suppliers may do them, but you will have to contact them directly.
There will also be local EWI installers and spreads to you who may take you on for some cheap labour on a job? ask......
