You’ve found the dream deal: an empty shop, office or little unit that could become flats. The numbers stack up, until someone says, “Have you checked planning?”.
Here’s the truth: sometimes you’ll need full planning permission and sometimes you can convert under permitted development (with prior approval). The difference matters because it affects timeline, cost, risk and your tax strategy, especially if you’re building a portfolio, developing to sell or structuring around UK/Dubai plans.
When you need full planning permission
You’ll usually need a full planning application if:
- The existing use isn’t eligible for the relevant permitted development route (for example, it’s not the right use class or the property sits outside the rules in your area).
- You’re not just changing use, you’re doing significant external works (new windows/doors, extensions, balconies, major façade changes). Permitted development can cover a change of use, but operational development often still needs full planning.
- The building is listed, in protected areas or has restrictions that mean the permitted development right doesn’t apply (common with certain heritage constraints and local policy).
- The council has strong local policies around loss of employment space, town centre vitality or housing standards that you’ll need to address through a full application.
If you’re planning a bigger redevelopment anyway like layout changes, bigger alterations, upgraded frontage, it can be cleaner to go full planning from the start – less patchwork, more certainty.
Exceptions under permitted development
In England, the big one investors talk about is Class MA. This is the change of use from Use Class E (Commercial, Business and Service) to Use Class C3 (dwellinghouses), subject to prior approval.
Two important updates:
- Since 5 March 2024, the old 1,500m² limit and the 3-month vacancy requirement were removed for applications submitted on/after that date.
- You still need prior approval with Class MA and the building must meet specific conditions, including use history requirements.
Prior approval is basically the council saying, “Fine, but prove it won’t be a disaster.” Expect scrutiny on things like transport/highways, contamination, flood risk, noise impacts, and whether the homes will be decent places to live.
Navigating Article 4 Directions
Here’s what usually catches people out: Article 4 Directions.
An Article 4 Direction lets a council remove permitted development rights in a specific area (or for specific uses). It doesn’t ban conversion but it means you must apply for full planning permission instead of relying on permitted development.
Article 4 is common in places trying to protect:
- town centres and key high streets
- office clusters / employment land
- areas already under housing pressure
So yes, that “easy” conversion you saw on TikTok may not be as easy as you think.
How to check local planning restrictions
Do this before you spend serious money:
- Search the council website for “Article 4 Direction” + the address/area. Many councils publish maps and boundary plans.
- Use the Planning Portal guidance to confirm use classes and whether prior approval may apply.
- Check the Local Plan policies (often sections on town centres, employment land, housing standards, design and sustainability).
- Look up the property’s planning history – it can reveal past refusals or conditions that still matter.
- If the deal is sizeable, consider pre-application advice (or a quick planning consultant review). It’s cheaper than buying a headache.
Planning application tips for success
Whether you’re going prior approval or full planning, the strongest applications are the boringly-prepared ones:
- Prove the current lawful use (leases, business rates, marketing history, photos, sworn statements where needed).
- Get ahead of common objections: noise, servicing, bin storage, cycle storage, daylight, privacy and access.
- If you’re converting above shops or near late-night venues, include a noise report early.
- Don’t ignore “small” details like refuse storage or awkward access routes – these are classic refusal triggers.
- Align the design with local expectations: “maximum units” is not the same as “acceptable living standards.”
Why this matters for your tax and wealth plan
Planning isn’t just a tick-box, it impacts your whole investment strategy:
- Holding personally vs FHL/ltd company/portfolio structure (and how profits get extracted)
- VAT and build-cost decisions
- Exit planning: refinance, sell, or keep as a long-term legacy asset
