Safety, thermal insulation and security – Part N of the Building Regulations allows for traditional leaded lights and stained glass as ‘glazing in small panes’.


Panels can be safely used in ‘critical locations’ – doors, - sidelights, - at low level. A traditional panel is classified as ‘single-glazing’.


A single-glazed door panel can be replaced ‘like-for-like’ with a leaded glass panel. For new doors - if the glazed area is less than 50% of the door area single-glazing still satisfies thermal performance requirements.

Question - ‘How easy is it to break through a leaded panel?’


Answer – it requires a lot of noise and a deal of bashing to break a hole through a leaded panel which is in good condition. A locked door still has to be opened.


Ultimately the aesthetic qualities of a leaded panel must be weighed against the practicalities of thermal performance and security.



Hand-painted and fired in the kiln


John Proctor Stained Glass

My glass painting is done in the traditional way using metal oxide pigments mixed with water and gum arabic, hand-painted with brushes and fired in a kiln.


Painted centres, motifs and inscriptions can make a panel really stand out.


Painting costs - a hand-painted Victorian style centre depicting a bird on a branch – about £70. Costs also depend on the complexity and density of the image and the number of kiln firings.


Glass choice has a significant bearing on the cost especially where ‘crown’ or other conservation glasses are called for. Plain leaded lights - Diamonds from £17.00/sq ft, quarries from £14.00/sq ft (horticultural glass), or from about £29.00/sq ft and £26.00/sq ft respectively for conservation glass.

Little more about me


I have been making traditional leaded glass panels for a living for about 14 years, before which I worked as a building surveyor doing architectural work, so I claim a good working knowledge of domestic buildings and an interest in period building styles and detailing. I work by myself so the whole process - design, glass-cutting, painting, making , sealing, cleaning , and fitting panels is done by me, predominantly using hand-tools.


Glass is cut by hand using a simple wheel-cutter, lead calme is cut with a knife, glass is shaped with grozing pliers (occasionally using a small electric glass grinder), soldering is done generally with electric irons.


A fair amount of elbow grease is also used. I choose not to use design software to generate drawings which are done on the drawing-board in time-honoured fashion. A full-size drawing is needed to make a panel, I find that drawing by hand helps the thinking process. I have made and repaired many leaded glass panels, of numerous designs and styles, mainly for domestic buildings, but also some ecclesiastical windows.


I try to involve my customers as fully as possible, especially in the design process, and I try to ensure that you are entirely happy with your finished panel. I thoroughly enjoy my job and take a pride in my work. My preference is to make door and window panels but I also turn my hand to painted hanging panels, panels for light-boxes, lanterns, etc.


I will also have a go at making virtually anything else from leaded glass such as terraria, small cloches, lamp-shades etc.

Painted glass - Where a panel conveys a design by its lead lines and different coloured glasses the degree of achievable detail is limited. Painted lines and shading give scope for a more highly detailed panel.

Leaded-lights - The beauty and character of a leaded-light lies in its faceting and the nature of the resulting reflections.


Leaded-lights are commonly diamond or ‘quarry’ lattices (rectangles). Cost depends on the size of panels, size of panes and their shape - diamond lattice requires more work and materials than rectangular quarries.


The same size panel with smaller panes requires the same amount of glass but more lead calme, more cutting, more solder, more cement - more expensive.
