What do conservation rooflights in Farnworth involve?
Our conservation rooflights service in Farnworth covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
From Farnworth to Walkden, Bolton and Radcliffe, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Farnworth
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
