Prior Approval in
Cardiff
Not every Cardiff project needs a full planning application, and not every project qualifies for permitted development either. Prior approval sits in between, a faster route with real legal deadlines, for specific categories like larger rear extensions and certain building conversions.
Get StartedThe Statutory Deadline Explained For Cardiff
Picking the wrong path for a Cardiff project, treating something as needing full planning permission when prior approval genuinely fits, or vice versa, wastes real time and real money. Nailing the classification early matters more than most people expect.
Each prior approval category in Cardiff carries its own conditions and its own statutory deadline, generally 42 or 56 days depending on which one applies, with the council’s review confined to specific matters set out in legislation rather than a broad planning assessment.
Confirming eligibility properly comes first for any Cardiff enquiry, not assuming a project qualifies for prior approval just because it sounds similar to one that does.

How We Help in Cardiff
Cardiff cases start with genuine eligibility checking, not an assumption the project qualifies, before any submission work begins.
What follows is prepared specifically for the prior approval process, addressing the defined matters Cardiff’s council actually assesses under this route.
Once submitted, we track the statutory deadline for your Cardiff project closely, since missing council communication near that date can genuinely matter.
Getting Cardiff Prior Approval Right The First Time
Picking a full application when Cardiff prior approval would’ve worked, or the other way round, is a genuinely costly slip we help people sidestep from the outset.
We treat the statutory deadline for Cardiff projects as something to work with properly, not race against carelessly, since a poor submission can still fail even on a fast track.
Prior approval genuinely doesn’t fit every Cardiff project, and we’d rather steer you toward the right route from the start than force a poor fit.
Not sure whether your project needs house extension planning permission instead? We check that too, before recommending prior approval as the route.

Can Cardiff’s council refuse prior approval for any reason they like?

Can I still get planning permission if prior approval isn’t right for my project?
Yes, if your Cardiff project doesn’t meet prior approval conditions, we simply prepare it as a standard planning application instead, the route changes but the project can usually still proceed.
How does Class MA relate to change of use for Cardiff properties?
Class MA is specifically about change of use for Cardiff properties, converting shops, offices, and similar commercial space to residential, a category we also cover in more depth on our change of use planning permission.
