Building regs for loft conversion used as office

Question

If I'm converting a loft for use as a home office rather than a bedroom, will I still need to meet certain building regs?

Building Regulations approval will always be required when converting a loft. A building control surveyor will come to site to inspect your conversion at various stages and will be responsible for issuing a completion certificate upon final inspection.

When it comes to a loft conversion, you are most likely to be concerned with Parts L, K, B and P of the Building Regulations.

Part L requires U-value targets for thermal efficiency to be met when you convert your loft into habitable space.
Part K concerns preventative measures from falling, collisions and impact, and requires a minimum headroom of 2m for all escape routes, including the stairs (although the rules are relaxed a little for staircases providing access to a loft conversion).
Parts B and P are concerned with fire and electrical safety respectively. Complying with Building Regs’ requirements on fire safety can be complex (more on that later in the article).

You need building regulations if you are doing any structural work, you will also need to meet fire regs, there will need to be away of escaping if there was a fire.
