How we approach conservation rooflights in Rickmansworth
We handle conservation rooflights across Hertfordshire, including Rickmansworth. In short: slim, low-profile steel-look rooflights for period and listed roofs. 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. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
We work across Hertfordshire, including Rickmansworth, and in neighbouring towns such as Watford and Chalfont St Peter. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Manual or electric opening
- Central vertical glazing bar

- Steel or aluminium frames
- Double glazed behind a period look

Things we check at survey
- Lead or matching flashings may be required

Consents for conservation rooflights in Rickmansworth
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.
