Rules that apply in Derry/Londonderry
Structural work
Structural alterations, such as widening the opening or fitting a new lintel, need building control approval from your council under the Building Regulations (Northern Ireland) 2012 before work starts.

Replacing a garage door is not usually development that needs planning permission in Northern Ireland. Listed building consent applies to listed buildings, and conservation-area controls, planning conditions or covenants can restrict changes to how a garage looks, so check before ordering.
Up-and-over to roller door conversion in Derry/Londonderry: questions
Is an electric roller door worth it for a garage in Derry/Londonderry?
That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Derry/Londonderry garage so you can compare.
Do you charge more for Derry/Londonderry than other towns in County Londonderry?
No. Guide prices are the same for Derry/Londonderry as for anywhere else we cover in County Londonderry. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.
Can I get a price for Derry/Londonderry without anyone visiting?
Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.
Can I message you a photo of my garage in Derry/Londonderry?
Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Derry/Londonderry. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.
Will I lose height in the opening with a roller door?
Not usually, if the box can sit behind the lintel inside the garage, which is the normal position. If there's too little headroom inside, the box can go under the lintel, which does reduce the clear opening height, or be face-fixed on the front of the wall. We measure this at the survey and tell you before you commit.
Can you keep my existing up-and-over frame?
Sometimes. If the frame is sound, square and securely fixed, it can stay as a finish around the opening and the roller door is fitted to suit it. If it's rotten, damaged or out of square, we take it out and prepare the opening for the new door. The survey decides which applies to your garage.
