Please folks, NEVER EVER use this company for anything. They must rate amongst the worst company in the UK for the quality of product, their customer service and aftercare. 3 years now and my sorry saga has not finished. They cam out today to fix faulty products. The engineer didn't have the right instructions, had the wrong parts to repair them with and now have to wait a further 6 weeks for them to repair their faults. their CEO Mike Gallacher is not contactable either. He sits in his office hiding away from the awful company he is leading. Emailed tens of times and never received a reply. I cannot give minus stars as I would have done. AVOID AVOID AVOID
