DIY front door replacement... do I need building regs?

[V33]

Self explanatory as above - do I need building regs/ FENSA approved fitter to replace a front door?

It will most likely be a solid door - no glass. As existing door is just replaced. I am a competent DIYer and will be looking at fitting it myself... but will leave it to the pros if it is a FENSA/ BC job?

Thanks

Not if it's just the door

so, I can go measure up, whip out the old door, stick in a new one (even if it looks different), tidy up and jobs a goodun?

I ask as I have work going on at the rear which is to be signed off by inspector - this won't be complete for a month or so and I would like to do the front door soonish and really don't want any surprises!
