Skylight and rooflight fitting in Port Talbot

Port Talbot is a town of heavy industry inside the Neath Port Talbot county borough. The 2021 census counted 31,550 people here, within a borough total of 141,931. The steelworks is the largest in the United Kingdom and one of the largest in the world, and an early account mentions the use of the river mouth as a port.

The land behind the town is older than any of that. The area's pennant sandstone formed in Carboniferous swamps 300 million years ago; it is brown, with red staining where iron from pyrite in coal has weathered to rust. Iron Age hill forts stood on Mynydd Dinas, Mynydd Margam, Mynydd Emroch and other hills nearby. Margam Country Park holds the remains of a Chain Home Low early warning radar station from the Second World War, and the Margam deer herd dates from Norman times, though deer in the area were mentioned during the Roman occupation. At Baglan, the church of St Catharine houses the Cross of Brancuf, an early Christian sculptured stone.

The modern borough is newer. After West Glamorgan County Council ended in 1996, Port Talbot's borough council merged with Neath and part of the Lliw Valley districts to form Neath Port Talbot County Borough, the council that now handles planning here.

Because the council covers the whole borough, the rules a Port Talbot address meets are the ones that apply across Neath Port Talbot, in Pontardawe and Neath too. The roof in front of you is what differs from street to street.

From Swansea the town is 9.16 miles by road, to the east, inside our 30-mile radius. Our patch also takes in Baglan and Cwmafan.

The first thing to settle about a rooflight is whether the home is a house or a flat. Houses can carry householder permitted development rights, and flats and maisonettes have none, so these rules apply to houses only. The Welsh Government's page on flats and maisonettes covers that side.

For a house, the conditions that let a rooflight go in without an application are set out in our rooflight planning guide for Welsh homes. Land is treated more strictly in a conservation area, in the Gower AONB, in Bannau Brycheiniog National Park and in a World Heritage Site, where a rooflight in the roof slope needs planning permission. Port Talbot sits beyond the Gower AONB boundary. Whether anything else on that list applies to your street is a question for the exact address.

Rights can also disappear. An Article 4 direction takes them away across a named area, and the planning permission first granted for a house may carry a condition that takes them away for that house alone. If the home is listed, a rooflight that would alter its special character needs listed building consent, applied for through the local authority under the Historic Environment (Wales) Act 2023. Cadw sets out what consent covers, and it includes work to fixtures and fittings inside as well as outside.

Building Regulations run alongside all this. The regulations class glazing like this as a controlled fitting, so putting it in counts as building work. A new opening will generally need approval, and our notification goes to local authority building control or to a registered building control approver. The Planning Portal for Wales describes the choice between the two kinds of building control body, and the choice is yours.

When an address sits near the margin of a rule, you can put the question to the planners, and a Lawful Development Certificate then records their answer formally. The certificate takes time to arrive but it stays on file for a later sale.

Rooms at the rear come first. A kitchen in a flat-roofed extension can take a flat roof rooflight or one of the glass lanterns, and they behave differently in rain, as the section on rain above explains. A rooflight on a house in Wales should reach 2.2 W/m²K. In the Welsh Approved Document L, a rooflight is the kind that stands on a kerb or upstand, and the figure is written for that kind. A lantern forming part of a new extension is one we check with the council first.

In the middle of the house, an inner hall or landing without a window is a job for a sun tunnel: daylight enters through a roof dome, runs down a mirrored tube and spreads from a ceiling panel. On a wet morning it gives the stairs a soft, even brightness, and a hall that was dark at midday gets some of the sky back.

Under the roof slope, a loft bedroom takes a roof window. In Wales a new or replacement roof window should meet 1.4 W/m²K or Window Energy Rating Band B. VELUX lists glazing options that include an easy-to-clean coating and safety lamination, whose laminated inner pane keeps accidental breakage out of the room. Which options come with a given window varies by model, so we check what suits yours. Roof windows sets out how the sashes open, and VELUX windows covers the brand.

A bathroom roof window needs a second thought, because the room makes the steam and the glass above it catches the blame. The extractor and the glazing work as a pair. Approved Document L also expects installed windows, roof windows and rooflights to be well fitted and reasonably draught-proof, which is a matter of workmanship as much as of product.

Port Talbot homes that already have an old unit can have it swapped. Misted glass is one reason; misted rooflights has the detail.

Each job begins with a free survey. You then receive a fixed written quote, and once the work is finished the 10-year workmanship guarantee is put in writing. To start, call 01792 929062 or use the survey form.
