We originally opted for a upvc door but the site survey highlighted that we could not have one due to the current building regulations and the required walk through. Upgrading to a more expensive composite door was suggested as this would meet the required regulations. When the new composite door was fitted it had been made to the wrong size (upvc size) therefore its not to the current building regulations. They send a surveyor out again who confirmed this. Customer services eventually called to discuss the problem and tried to fob me off by saying they couldn't make it to the building regs. Strange how they send me a FENSA certificate self certifying that it is to regs. Tried to escalate the complaint but a week later and still waiting to hear back. Presume I will have to take this further to get resolution. Such a shame as the door is good quality and sensibly priced.
