How we approach sliding rooflights in Morden
Our sliding rooflights service in Morden covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Jobs in Morden are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Double or triple glazing
- Anthracite, black or RAL frames
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge
- Integrated balustrade on some ranges
- Daylight down the stair when closed
- Full-width, walk-out access to a roof terrace
Before you order: points to check
- Weight and point loads need a structural check
- The stair opening and headroom must meet Building Regulations
Planning and building rules for Morden
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sliding rooflights in Morden
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Is the survey in Morden free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Morden?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
