I can certainly endorse this, I've used Prestige for over 3 years now; they are extremely knowledgeable, offer an excellent service and are very reasonably pricedHi Badgolfer.
Don't know whether this will be any good for you, but I use Prestige Servicing in Stockton on Tees for my servicing. I have found them to be knowlegable and reliable whilst the prices are reasonable too.
Their web site is http://www.prestigeservicing.co.uk/
Hope that's some help.
