Loft conversion skylights in Castlereagh: what is involved?
For Castlereagh homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for loft conversion skylights include loft conversions and rooms in the roof.
Jobs in Castlereagh are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Blackout and thermal blinds
- Balcony roof windows on some ranges
- Centre-pivot or top-hung
- Electric or solar opening
- Combination and stacked layouts
- Set out on the rafters before plastering
- Fits alongside dormers
Before you order: points to check
- Escape-window requirements apply to some loft rooms
- Insulation and vapour control details matter for condensation
Do you need permission in Castlereagh?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. Listed buildings also need listed building consent from the council.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about loft conversion skylights in Castlereagh
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
