Conservation rooflights in Hertford: what is involved?
Conservation rooflights in Hertford means slim, low-profile steel-look rooflights for period and listed roofs. We cover the SG13 district and the rest of Hertfordshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
Hertford is around 27 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG13 district.

Do you need permission in Hertford?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
