Building a new home on your own land — or on a plot you are buying — is one of the most rewarding property projects possible. It is also one of the most complex. Planning permission is the critical gate, and understanding how to navigate it can be the difference between a project that completes and one that stalls for years. This guide covers the full process from initial assessment to decision notice.
Outline vs Full Planning Permission
There are two main routes for new build applications:
Outline planning permission establishes the principle of development — that a dwelling can be built on this land. It does not fix the detailed design. Reserved matters (appearance, landscaping, layout, scale, access) are submitted separately, usually within 3 years of outline consent. Outline permission is useful for proving a site has development potential before investing in detailed design costs.
Full planning permission covers everything — principle, design, access, and all reserved matters — in a single application. This is the most common route for self-build projects where the design is already known. Consent is typically valid for 3 years, within which you must make a material start on site.
What Councils Weigh: Material Considerations
Planning decisions are made against the development plan (the local authority's adopted local plan), with the National Planning Policy Framework (NPPF) as a material consideration. Councils must approve applications unless there are material reasons to refuse. Material planning considerations include:
- Design and visual impact on the surrounding area
- Impact on neighbours (overlooking, overshadowing, noise)
- Access and highway safety
- Flood risk (check the Environment Agency's flood zone map before purchasing any plot)
- Ecology and biodiversity net gain (a mandatory 10% BNG requirement from February 2024)
- Trees and hedgerows
- Heritage and archaeology
Things that are not material planning considerations: the applicant's personal circumstances, the impact on property values, competition with local businesses, and private rights such as covenants.
How to Read the Local Plan
Before spending anything on design, read your local plan. This is the council's spatial strategy document — it designates land for housing (allocated sites), protects other land (Green Belt, AONB, Local Green Space), and sets out policies on design, density, and sustainability.
Key designations to check:
- Green Belt: new development is only permitted in very special circumstances — this is an extremely high bar
- AONB (Areas of Outstanding Natural Beauty): major development is refused unless in the national interest
- Flood Zone 2 and 3: sequential test required; Zone 3b (functional floodplain) effectively prohibits new dwellings
- Conservation Area: design standards are higher; some PD rights are removed
Your local plan is available on the council's website. Use the policies map (an interactive GIS layer) to identify all designations affecting your site.
Pre-Application Advice: Always Worth It
Pre-application advice is a formal paid service offered by every LPA. You submit a brief description and basic drawings; the council's planning officer responds in writing with a view on likelihood of success and any issues to resolve before submission.
| Council Type | Typical Pre-App Fee |
|---|---|
| District/Borough council (householder) | £50–£200 |
| District/Borough council (minor new dwelling) | £200–£500 |
| London Borough | £200–£600 |
| National Park Authority | £100–£400 |
Pre-application advice is not binding, but it dramatically reduces refusals. Officers who have engaged pre-application are more invested in helping you reach a compliant design. Skipping it to save £300 and then receiving a refusal — with the associated 3–6 month appeal process — is a false economy.
The 8-Step Planning Application Process
- Appoint an architect or planning consultant — for a new build, full drawings (site plan, floor plans, elevations, sections) are mandatory
- Carry out surveys — topographic, ecological, flood risk assessment if needed
- Prepare a Design and Access Statement — required for most new dwellings; explains the design rationale
- Submit via the Planning Portal (planningportal.co.uk) — all applications in England
- Council validates the application — checks all required documents are present (allow 5–10 working days)
- Statutory consultation period — 21 days for neighbours and statutory consultees to comment
- Officer assessment — planning officer prepares a report for delegated decision or committee
- Decision notice issued — target 8 weeks for minor applications, 13 weeks for major (more than 10 dwellings)
Planning Fees (England, 2025)
| Application Type | Fee |
|---|---|
| Householder application | £528 |
| Full application — new dwelling | £528 per 0.1 hectare of site area (residential) |
| Outline application | £462 per 0.1 ha |
| Reserved matters | £462 per 0.1 ha |
| Prior approval (some barn conversions) | £120 |
Wales, Scotland, and Northern Ireland operate separate fee scales — check the relevant national planning portal.
Self-Build Routes and Incentives
If you are building your own home, several incentives apply:
- Custom Build Register: local authorities must maintain a register of self-build demand. Registering formally does not guarantee a plot, but councils are supposed to allocate sufficient serviced plots to meet registered demand.
- Community Infrastructure Levy (CIL) exemption: self-builders are exempt from CIL on their principal private residence. You must apply before commencing work — failure to do so removes the exemption.
- HMRC VAT reclaim (VAT431NB): materials used in a new self-build can qualify for a VAT refund via the DIY Housebuilder Scheme. Claim within 3 months of completion.
Ecological Survey Triggers
Certain protected species require surveys before planning can be determined. These add cost and time — often 3–6 months, as surveys are season-dependent.
- Great Crested Newts: required if a pond is within 500m of the site
- Bats: required if the site includes buildings, trees, or hedgerows (roost potential survey required April–October for emergence/re-entry surveys)
- Dormice: required in areas with hazel coppice or thick hedgerow networks
Commission a preliminary ecological appraisal (PEA) early — typically £400–£800 — to establish which species surveys are required and when. See our guides to permitted development vs planning and building regulations approval for what comes after you receive your planning consent. And when your new build is complete, use our new build snagging list to identify and document defects before handover.
