Thinking about a project in Milton Keynes?
Send us your sketch and a few photos — we’ll tell you if it’s Permitted Development or if you’ll need a full planning application.
Summary: Most small home projects in Milton Keynes can be built under Permitted Development (PD). However, larger extensions, garage conversions, and anything affecting highways usually need full planning approval. Milton Keynes City Council has its own quirks — especially around parking, estate design codes, and conservation areas — that can affect whether permission is granted. If you’re unsure, start with our Planning Permission Guide and cost breakdown.
Quick Answer: Do You Need Planning Permission in Milton Keynes?
If you’re adding a modest rear extension, converting your loft, or installing solar panels, there’s a good chance you can use PD rights. But if you’re altering the front of your home, changing parking arrangements, or building near a road, Milton Keynes City Council will usually require a full application. For clarity on your specific house type, see Do I need planning permission?
When Planning Permission is Needed
You’ll generally need planning permission in Milton Keynes if your project involves:
- Two-storey side or rear extensions.
- Front-facing alterations (including porches over 3m²).
- Garage conversions where parking is reduced.
- Flats or maisonettes (PD rights don’t apply here).
- Properties in conservation areas or Article 4 zones.
Permitted Development in Milton Keynes
Like the rest of England, Milton Keynes follows the national PD rules. Common PD projects include:
- Single-storey rear extensions up to 3m (terraced/semi) or 4m (detached).
- Loft conversions up to 40m³ (terraced) or 50m³ (detached/semi).
- Outbuildings under 2.5m tall within 2m of the boundary.
- Solar panels flush to the roof slope.
Not sure if your idea fits Permitted Development?
We’ll check your project against PD rules and let you know if you need a full planning application.
Milton Keynes Council Quirks to Watch Out For
Milton Keynes has some particular quirks worth noting:
- Estate design codes: Many estates (e.g., Brooklands, Oxley Park, Broughton) have strict visual guidelines. Even minor changes (fences, windows, materials, paint colours) may need consent.
- Parking requirements: Almost every application is checked against adopted parking standards. Losing a space without a replacement is a common reason for refusal.
- Article 4 Directions: Some HMOs and conservation areas have Article 4 restrictions removing PD rights.
- New-build conditions: Developers often insert conditions that remove or limit PD rights entirely — very common across MK’s newer estates.

FAQs – Planning Permission Milton Keynes
Planning permission Milton Keynes — where do I start?
Begin by checking if your idea fits Permitted Development. If not, apply via the Planning Portal and select Milton Keynes City Council as your Local Planning Authority. We can prepare compliant drawings and submit on your behalf.
How long does planning permission last in the UK?

How long is planning permission valid in Milton Keynes?
Validity mirrors the national rule: typically three years to commence. Time extensions are rare; if expiry is close, consider a revised application. See our Planning Permission Guide.
Does planning permission cost?
Yes. A standard householder application is currently £258 (application fee). Budget also for plans, surveys and possible reports (e.g., parking/heritage). Our costs guide explains typical totals.
Do you need planning permission for Permitted Development?
No — PD projects don’t need planning permission. However, we recommend a Lawful Development Certificate to prove PD status to buyers and lenders. We can prepare and submit this for you.
Is planning permission free?
No. Applications have fees, and you’ll usually need professional plans. Some advice services are free, but decisions and certificates carry charges via the Planning Portal.
Milton Keynes Council planning policy — what should I know?
Decisions apply the MK Local Plan and guidance (e.g., parking standards and estate design codes). Expect scrutiny on parking loss, street scene, and materials. If you’re on a design-controlled estate, match the approved palette and rhythms.
Planning permission time limits (UK) — are there any traps?
Yes. You must discharge any pre-commencement conditions before starting. Starting without discharging can make the permission unlawful, even if you begin within three years.
Milton Keynes planning contact number — how do I reach them?
Use the council’s planning contact page for the latest phone and email details (they change periodically). You can also message us — we deal with MK daily and can advise what to ask for.
Milton Keynes Council planning application requirements
Typical validation items include: application form, fee, ownership certificate, location plan, block/site plan, existing & proposed drawings, elevations/sections, and (where relevant) parking statements, heritage notes, or design & access statements.
Where can I find my planning permission?
Search the MK online planning register for your address to view decisions and conditions. If you need a copy for conveyancing, download the decision notice and approved plans; we can help interpret conditions.
Is planning permission a legal requirement?
Yes — if the work is “development” and not covered by PD. Building without it risks enforcement. When unsure, seek pre-application advice or apply for an LDC to confirm PD status.
