The short answer
Planning sits with Vale of White Horse District Council, and its building control is the Southvale service run jointly with South Oxfordshire. A registered building control approver is the private alternative. A matching repair seldom needs either; a large re-covering, a heavier covering or a listed building will.
Most work on a Kingston Lisle roof needs no approval at all. The questions arrive when a job grows or when the building is special.
Q3.1When does building control come in?
The Planning Portal puts the line for re-roofing at 25 per cent of the total building envelope and 50 per cent of the roof: re-covering kept beneath both lines normally needs no building control application, while one that goes over brings Building Regulations in, with a possible insulation upgrade. Moving to a markedly heavier covering, 15 per cent or more, brings approval in as well. The district's route is Southvale Building Control, shared with South Oxfordshire, with a registered building control approver as the private alternative. We tell you which suits the job, and if it is notifiable we send in the notification.
Q3.2What does the conservation area change?
Kingston Lisle has a designated conservation area. Matching repairs leave a building looking as it did and rarely need an application. A change of covering, or new openings in a visible slope, is the kind of work the council examines. For roof windows in particular, our page on roof window planning explains the position.
Q3.3What should you tell us first?
Four details save time: roughly when the house was built, what the roof is covered with, where the water shows inside, and whether the building is listed or sits within the conservation area. A mobile photograph of the ceiling stain and one of the roof from the lane are plenty. With those in hand we can say whether a quick repair is likely or whether the job looks bigger, and book the survey around your diary.
Q3.4What happens before the scaffold goes up?
Send us a few photographs and the approximate age of the house. We will tell you what is likely to be involved. The survey confirms it, and photographs from your roof travel with the written price. Where the job turns out to be a repair, the quote says so in plain terms.
A quote sent without a survey is a guess, and we avoid guessing: the written price comes after the roof has been seen. Old farm buildings and roof spaces here can shelter bats or nesting birds, which are protected, so we check before disturbing one.
