Bespoke & shaped rooflights for Welwyn Garden City: the essentials
We handle bespoke & shaped rooflights across Hertfordshire, including Welwyn Garden City. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of bespoke & shaped rooflights for angled ceilings, corners and architect-designed extensions.
From Welwyn Garden City to Hatfield, Hertford and St Albans, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Welwyn Garden City
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Will I need planning permission in Welwyn Garden City?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
Is the survey in Welwyn Garden City free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
