Please remember that in England & Wales you must by law apply for approval from your local building control office (local authority) unless you employ an OFTEC registered installer to do the work. OFTEC installers are able to self certify their work and can sign it off without Building Control Notification. You can find more information about OFTEC at www.oftec.co.uk.
Hope this helps.
