| Check | Practical answer |
|---|---|
| Planning authority | Reading Borough Council — verify the actual parcel, any special planning jurisdiction and site type |
| Adopted development plan | Reading Borough Local Plan adopted 4 November 2019 |
| Specific biodiversity policies | EN12 – Biodiversity and the Green Network; EN14 – Trees, Hedges and Woodland; EN16 – Pollution and Water Resources |
| Emerging plan status | Reading submitted its Local Plan Partial Update on 9 May 2025 for independent examination. Hearings ran in November 2025 and February 2026. In September 2026 the council approved consultation on an additional main modification committing to an early review because the Inspector identified an evidence gap for Gypsy/Traveller accommodation and water-quality effects of proposed growth. The emerging update is not adopted as of 10 November 2026. The current 2019 Local Plan and its EN12/EN14 environmental policies remain the adopted starting point; proposals from the update must not be mistaken for new binding ecology policy. |

| Protected sites | Independent Habitats Regulations or protected-species evidence where a credible impact pathway exists |
Planning authority and policy
Local planning requirements for Reading
Confirm the planning authority
Reading Borough Council is a unitary planning authority. Berkshire is the wider geographic and LNRS grouping. Wokingham, West Berkshire and neighbouring Oxfordshire districts have separate planning policies.
See BNG in Berkshire and the South East regional guide.
Use the adopted development plan
Reading Borough Local Plan adopted 4 November 2019. Relevant policies include EN12 – Biodiversity and the Green Network; EN14 – Trees, Hedges and Woodland; EN16 – Pollution and Water Resources.
The Local Plan Partial Update, submitted in May 2025, remains under examination. Main modifications and water-quality evidence have been considered during 2026. The adopted 2019 plan remains the policy starting point.
Establish the gain target
Eligible development normally needs at least 10% statutory gain. Establish the applicable target using current national policy, any relevant site-allocation policy and existing permission.
Plan habitat retention, suitable enhancement and long-term management alongside the site layout. Check the national biodiversity planning policies when establishing obligations.
Check dates and exemptions
For applications from 6 August 2026, sites up to 0.2 hectares may qualify for an exemption if no onsite priority habitat is adversely affected.
Householder, de minimis, temporary-development and transitional rules have their own conditions. Record the application date, site area and supporting habitat evidence.
Use the BNG exemptions guide to identify the relevant route.
Nature recovery and local geography
Local habitats and nature recovery in Reading
Use the local nature recovery map
The published Berkshire Local Nature Recovery Strategy provides priorities and mapped opportunities for habitat recovery. It was published on 7 October 2025.
For Reading, consider Thames and Caversham riverbanks, the Kennet and canal corridors, Fobney wetlands and inner-city sites. Match the actual site location and proposed habitat to a relevant recovery measure.
Local habitats to consider in Reading
Use the landscape context to scope the survey, then record the habitats actually present within the site boundary.
| Local setting | Potential habitat or evidence issue |
|---|---|
| Thames riverside and Caversham | Riverbank trees, grassland and riparian habitats along the Thames, with floodplain and watercourse-unit assessment where the actual red-line is connected. |
| River Kennet and Kennet & Avon Canal | River/canal fringes, backwaters, reedbed and wet grassland; consider separate watercourse condition, floodplain design and protected riparian species. |
| Fobney Island and Southcote | Documented restored local wetland and meadow habitat at Fobney Island; a nearby proposal still needs its own UKHab survey and lawful site ecology screening. |
| Station Hill and inner Reading brownfield | High-density regeneration parcels can support established trees, scrub, walls or green roofs; do not assume a zero ecological baseline from previous use. |
Plan protected-site and species evidence
Consider actual river, wastewater and protected-site pathways when scoping a Reading proposal. Any relevant Habitats Regulations issue or Thames Basin Heaths effect is assessed separately from the metric.
Along the Kennet and Thames, coordinate watercourse condition, riparian habitat, floodplain and species evidence. Water-quality questions in plan-making should be translated into the evidence relevant to the particular development.
Local planning context
Habitat lessons from Fobney Island
Reading Borough Council describes wetland, reedbed and hay-meadow restoration at Fobney Island between 2011 and 2013. The work also connected the river with its floodplain and provided fish refuge. It offers a local example of designing habitat around water and landscape functions.
Planning and delivery
Preparing evidence and delivering biodiversity gain
Prepare the habitat baseline and metric
Start with the site’s habitat baseline and condition. Use the appropriate statutory metric; the Small Sites Metric is suitable only where its eligibility conditions are met.
In Reading, survey Thames and Caversham riverbanks, the Kennet and canal corridors, Fobney wetlands and inner-city sites where these occur within or affect the proposal. Record the actual habitat condition and relevant watercourse evidence.
See BNG assessments and habitat surveys, habitat condition assessment and Small Sites Metric assessments.
Prepare the planning submission
Confirm the planning authority, application date, relevant policies and whether statutory BNG applies. Then agree a proportionate submission scope with the council.
- An applicability or exemption explanation supported by site evidence.
- The red-line boundary, baseline habitat plan and metric where required.
- Proposed layout, retained habitats and feasible habitat gains.
- Any protected-species, watercourse, drainage or Habitats Regulations evidence.
Test the layout against local habitat constraints
Retain sensitive habitats and useful connections where possible. Use these questions to compare realistic layout and habitat options.
| Design decision | Evidence to bring together |
|---|---|
| Confirm the baseline | Map the habitats, trees and relevant watercourses before fixing the footprint. Include condition and any protected-species evidence. |
| Compare realistic options | Test retention, enhancement and habitat creation against the layout, drainage, access and long-term management. |
| Check the delivery route | Calculate each relevant unit category. Record legal security, management responsibilities and any registered off-site allocation. |
Choose habitats suited to the site and its long-term management. Match nature recovery measures to the published LNRS map, then calculate all relevant unit categories.
Development and regeneration context
Reading’s high-density and riverside developments can combine constrained footprints with established trees and green-blue links. For Station Hill or other regeneration settings, establish the actual baseline and planning conditions before allocating roof, landscape or off-site habitat gains.
A practical Reading planning example
Illustration: a Kennet-side development removes grassland while retaining trees and riverbank habitat. Calculate relevant unit categories and test the proposed management. Review drainage and species evidence alongside the layout so that habitat and watercourse improvements remain feasible.
Plan off-site delivery and long-term management
Calculate the genuine shortfall before committing to off-site units. Apply the relevant gain hierarchy, habitat trading rules and location requirements to the proposed delivery route.
Use the Berkshire Local Nature Recovery Strategy to explore habitat opportunities. Confirm registration, suitable units and current availability directly with the proposed supplier.
Read about off-site biodiversity units, Biodiversity Gain Plans and Habitat Management and Monitoring Plans.
Council and delivery costs
What should your Reading BNG budget cover?
Budget for habitat surveys, metric calculations, planning reports and any gain-plan or management work. The scope depends on the site, habitat types and planning stage.
Separate ecology and metric work from any watercourse, flood, drainage or protected-species assessment. Include the delivery and ongoing management costs of proposed roofs, landscaping or off-site units.

Use these questions to organise the planning, habitat and delivery information for your site.
Which authority and adopted plan apply?
Reading Borough Council is a unitary planning authority. Berkshire is the wider geographic and LNRS grouping. Wokingham, West Berkshire and neighbouring Oxfordshire districts have separate planning policies.
Reading Borough Local Plan adopted 4 November 2019. Relevant policies include EN12 – Biodiversity and the Green Network; EN14 – Trees, Hedges and Woodland; EN16 – Pollution and Water Resources.
How should I treat emerging policies?
The Local Plan Partial Update, submitted in May 2025, remains under examination. Main modifications and water-quality evidence have been considered during 2026. The adopted 2019 plan remains the policy starting point.
Establish the applicable gain target using current national policy, any relevant up-to-date site-allocation policy and existing permission.
How do I use the nature recovery map?
Match the actual site and proposed habitat to a relevant measure in the Berkshire Local Nature Recovery Strategy. Record the map and survey evidence supporting the metric entry.
Could an exemption apply?
For applications from 6 August 2026, sites up to 0.2 hectares may qualify if no onsite priority habitat is adversely affected. Other exemptions and transitional provisions have separate conditions. Record the development type, date, red-line area and habitat evidence.
Which separate ecological issues matter?
Consider actual river, wastewater and protected-site pathways when scoping a Reading proposal. Any relevant Habitats Regulations issue or Thames Basin Heaths effect is assessed separately from the metric.
Along the Kennet and Thames, coordinate watercourse condition, riparian habitat, floodplain and species evidence. Water-quality questions in plan-making should be translated into the evidence relevant to the particular development.
When is the final gain plan needed?
For eligible ordinary applications, the statutory Biodiversity Gain Plan is normally approved after permission and before development starts. Agree earlier planning evidence with the authority and identify feasible management and any off-site delivery route.

Project support
How ACP can help with your Reading project
ACP can help scope the habitat surveys, metric calculations and planning reports needed for your Reading proposal. Early advice is most useful while the layout can still change.
We can consider Thames and Caversham riverbanks, the Kennet and canal corridors, Fobney wetlands and inner-city sites alongside the site’s planning route and proposed works.
Local planning questions
Frequently asked questions about BNG in Reading
For a site-specific question, discuss your project with ACP.
Which biodiversity policy applies in Reading?
Reading Borough Council's adopted 2019 Local Plan, including EN12 Biodiversity and the Green Network, is the current starting point. The submitted Partial Update remains under examination, not adopted.
Has Reading adopted the 2025–2041 Local Plan Partial Update?
The Partial Update was submitted in May 2025 and remains under examination following the 2026 modifications process. The adopted 2019 Local Plan remains the starting point.
What can a Reading developer learn from Fobney Island?
Fobney Island provides a documented local example of wetland and floodplain restoration. For any unit purchase, check the proposed supplier’s actual gain-site registration, allocation, habitat type and current availability.
Does every Reading development need a nutrient-neutrality payment?
Establish the proposal’s actual wastewater, river and protected-site effects. Any required water-quality or Habitats Regulations evidence should be scoped alongside BNG. The metric calculation alone does not determine those separate requirements.
Is 10% biodiversity net gain compulsory for every Reading project?
No. Eligible applications normally require at least 10%, but the 2026 national exemptions, application date, development type and priority habitats can change the position. Other ecological and planning policies can still apply.
Do I need an ecology survey if my application is exempt?
Not automatically for every site, but an exemption from mandatory BNG does not remove protected species, designated site, tree or local ecological planning duties. The need for evidence depends on what the proposed work may affect.
Does a published local nature recovery map itself grant permission?
No. The Berkshire Local Nature Recovery Strategy helps target recovery priorities. It does not prove a habitat exists on a parcel, award metric uplift automatically or replace planning permission. Compare the map with actual habitat surveys and the mapped measure.
Can I buy off-site units instead of avoiding habitat loss?
The applicable gain hierarchy and trading rules still matter. Registered off-site units can be part of a lawful delivery strategy, but their type, legal securing, allocation and availability must be checked. Statutory credits are a separate last-resort route.
When is a final Biodiversity Gain Plan approved?
For applicable ordinary planning permissions, approval normally follows permission and precedes the start of development. Planning applications still need proportionate evidence of deliverability; the local authority's current validation guidance must be checked.
Is floodplain habitat around the River Kennet interchangeable with urban landscaping units?
Not automatically. River Kennet and Thames settings can involve floodplain, watercourse and wetland features. The statutory metric uses separate watercourse and area units, and the actual baseline and trading rules determine an appropriate scheme.
