About Abergavenny and the NP7 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
We cover Abergavenny as part of Gwent, about 16 miles from Newport, Gwent.
Neighbouring places we cover include Pontypool (8 miles), Ebbw Vale (9 miles), Tredegar (10 miles).
How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Wales?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
