Skylight and rooflight fitting in Tircoed

Tircoed forest village is a suburb between the villages of Penllergaer and Pontlliw. Heading north-west, Swansea to Tircoed is a drive of 6.45 miles. Wikipedia describes it as built from the late 1980s onwards, and as currently consisting of 470 houses clustered around a village hall, pond and green, reached from the A48 along a road about half a mile long. The population in 2011 was around 884 people.

The village has its own community radio station, originally Radio Tircoed and rebranded in 2025 as Welsh Coast Radio.

Pond, green and hall give the village a centre, and the places around it are close. The surrounding places include Penllergaer, Pontlliw, Grovesend and Gorseinon, all with pages of their own, and we fit and replace rooflights across that stretch.

A village laid out around a green and built over a period of years has houses of different ages, so the glass in them will differ too. General to houses of that era, the roofs are often pitched, a loft may have been converted at some point, and a rear extension may have added a flat roof. Those are patterns, not facts about particular streets. A rooflight that was fitted when a house was new is by now decades old, and that age is the first thing worth checking.

Some Tircoed houses will need nothing more than a swap of what is already there. Others will want glass where there is none, over a loft room, a landing or a rear extension. The survey sorts one kind of job from the other, and the answer depends on the roof underneath.

Planning for a Tircoed address sits with City and County of Swansea Council. For a house on land with extra protection, which means a conservation area, the Gower AONB, Bannau Brycheiniog National Park or a World Heritage Site, a rooflight cut into the roof slope needs planning permission. Tircoed itself lies outside the Gower AONB. For a house elsewhere, the planning permission guide for skylights in Wales explains when no application is needed.

A newer estate has one extra thing to read. When a development was approved, the permission may have carried conditions, and a condition can remove permitted development rights for the houses it covers. A council can also remove them across an area with an Article 4 direction. Householder rights were never given to flats or maisonettes. If you are unsure, ask the planning team, and the formal record, if you want one, is a Lawful Development Certificate.

Listed buildings follow a different path altogether. A rooflight that would affect a listed building's character as a building of special architectural or historic interest needs listed building consent, under the Historic Environment (Wales) Act 2023, and the consent covers work inside and out. Cadw explains the consent, and it is applied for at the local planning authority.

Building Regulations are a separate set of rules and a separate decision. Approval is generally required for opening up a roof to a new rooflight. For notifiable work we handle the Building Regulations notification with local authority building control or a registered building control approver. A loft room that turns into a bedroom also brings in the means-of-escape rules, which our Building Regulations guide for skylights sets out.

Replacement work follows its own logic. Swapping a window for its twin counts as building work and repairing it does not, while a pane renewed in a frame you keep is outside the energy rules. A roof window that has to be replaced entirely should meet 1.4 W/m²K, or Window Energy Rating Band B, under Approved Document L (Wales), and a new or replacement rooflight should meet 2.2 W/m²K.

Fit counts alongside glass. The same document calls for installed windows, roof windows and rooflights that are fitted properly and keep draughts reasonably in check, so the sealing round the frame deserves as much attention as the pane.

Replacing an old roof window can be simpler than people expect, because the opening in the roof already exists. A roof window of the right size can go back where the old one came out, and the flashing needs looking at too. The survey checks the size and the condition of the opening, and whether the roof timbers around it are sound.

Ventilation is the detail people miss in a swap. Approved Document F (Wales) wants a home to keep at least the ventilation it had before a window changes, which means a unit that came with trickle vents is replaced by one whose vents are no smaller. A house that relies on natural ventilation can meet the rule in other ways, so ask about it early. A swap in the same opening is also the moment to revisit the opener, the glazing and the position of the sash, because the hole in the roof is already cut.

An opener is worth thinking about for a loft room. A hand-operated window belongs on glass within easy reach. An electric one suits a sash up high, and VELUX's rain sensor closes solar and electric models when it rains. Whether an old manual window can be made electric depends on the window, so that is a question for the survey.

Behind the house, a flat-roofed addition takes a flat roof rooflight on its kerb, or a roof lantern over its upstand. Where a lantern is planned on an extension that has not yet been built, the council is asked what applies, and we confirm it with them. A hallway or landing with a loft overhead and no outer wall can take a sun tunnel, and our guide to rigid or flexible tubes explains how the route between dome and ceiling is chosen.

If an older unit has clouded between its panes, the seal has usually failed, and our misted rooflight replacement covers that.

Every job begins with a free survey and ends with our 10-year workmanship guarantee in writing, and a fixed written quote sits between the two. To book, ring 01792 929062 or use the survey form.
