Introduction
For most Glasgow commercial developments, an ecological impact assessment doesn't stand on its own - it sits alongside the site's tree survey, and on sites where bats, badgers or nesting birds are flagged as a risk it leads into a full protected species survey. Where mature trees are being kept through a build, the same findings feed into tree preservation planning during construction, so root protection areas and habitat constraints get designed around together rather than picked up separately later in the programme.

What's Included in the Report, and What's Priced Separately
- Desktop data search using biological records centre data, national habitat databases and historic aerial photographs to establish baseline conditions
- Site visit and Preliminary Ecological Appraisal, including Phase 1 Habitat Survey and UK Habitat Classification (UKHab) mapping
- Targeted protected species surveys where the desktop study or site visit flags a risk - bats, badgers, breeding birds, great crested newts, and water vole, otter, red squirrel or reptiles where relevant
- A written report covering methodology, baseline conditions, impact significance and a mitigation hierarchy (avoid, mitigate, compensate)
- Biodiversity Net Gain calculation and enhancement planning to meet the 10% statutory requirement
- Planning application support - consultation responses and liaison with the planning authority's ecology advisor
Not Included / Costed Separately
- Physical mitigation or enhancement works (habitat creation, hedge and tree planting, SuDS installation) - these are quoted and delivered as a separate project once the report specifies what's needed
- Any protected species licence application to Natural England or NatureScot - the survey establishes whether one is needed; the application itself, and any translocation work, is arranged and priced separately
- Repeat surveys if a planning submission slips past the relevant species' survey window and the data expires
- Council planning application fees, paid direct to the local authority
- Ongoing Ecological Clerk of Works supervision during construction - available, but billed as a separate phase once work starts on site
PEA, Standalone EcIA or Full EIA Chapter: Which Applies to Your Site
| Assessment type | When it applies | Typical price band | Typical timescale |
|---|---|---|---|
| Preliminary Ecological Appraisal (PEA) | Early feasibility or pre-application, before any protected species surveys are known to be needed | Covered within the free scoping visit | Findings within days of the site visit |
| Standalone EcIA | Most commercial developments below the statutory EIA thresholds | £2,500-£5,000 basic; £5,000-£10,000 with protected species surveys | Report 2-4 weeks after fieldwork; fieldwork itself is season-dependent |
| EIA ecological chapter | Schedule 1 developments always; Schedule 2 where significant effects are likely | £7,500-£15,000 | Runs alongside the wider EIA programme, typically several months |
| Protected species survey add-on | Bats, badgers, breeding birds, great crested newts or similar flagged as a risk | £500-£2,500 per species group | Tied to that species' survey season (e.g. bats April-October) |
| Biodiversity Net Gain assessment | Any development needing to demonstrate the 10% statutory BNG requirement | £1,500-£5,000 | Alongside the habitat survey, 2-4 weeks to report |
One NPTC-Qualified Surveyor for the Trees and the BNG Calculation
The person who walks the site for the ecological impact assessment is the same person who holds the NPTC Professional Tree Inspection qualification, so trees aren't scored for bat roost potential, cavities and nesting habitat from a site photograph or a generic habitat checklist - they're read by someone trained to assess tree condition first-hand, the way a tree surgeon reads deadwood, bark lift and cavity depth before deciding whether a limb is sound to climb. That distinction matters most on the sites that are easy to get wrong: a mature tree with old woodpecker holes or lifting bark can look unremarkable in a photo but represent real bat roost potential once someone who inspects trees for a living has actually climbed up to check it. The same site visit also produces the Biodiversity Net Gain calculation under the UK Habitat Classification (UKHab) metric that Scottish planning authorities expect against the 10% statutory requirement, so the tree condition data and the BNG baseline come from one inspection rather than two contractors working to two different survey standards. Trading in Glasgow since 2005 and fully insured for commercial site work, that's the practical judgement applied to every report, not a box-ticking exercise that treats every tree the same.
Coverage Beyond the City: Dunbartonshire, Renfrewshire and the Lanarkshire Corridor
On the south side, Pollokshaws sits at the edge of Pollok Country Park, whose established woodland and watercourses support bat and bird populations that regularly extend onto adjacent development sites, so surveys in that area need to account for the park's ecology from the outset. West Dunbartonshire sites around Clydebank and Dumbarton typically sit close to the Clyde and Leven floodplains, which raises water vole and otter as realistic survey considerations rather than a formality. Further west, Renfrewshire towns including Renfrew, Johnstone and Barrhead, plus Greenock in Inverclyde, sit within Gryffe, Black Cart and Clyde estuary catchments with a similar watercourse profile. To the north, East Dunbartonshire's Bearsden, Milngavie, Kirkintilloch and Bishopbriggs sit against the green belt edge near the Campsie Fells, while East Renfrewshire's Giffnock, Clarkston and Newton Mearns sit on the equivalent green belt boundary to the south. South Lanarkshire sites around Rutherglen, Cambuslang, Blantyre, Bothwell and Baillieston follow the Clyde Valley, an area with mature woodland cover including the woodland around Bothwell Castle. The rural Stirlingshire villages of Strathblane, Killearn, Balfron and Fintry tend to bring more ancient woodland and watercourse constraints than urban sites, while Bo'ness, in Falkirk council area near the Firth of Forth, is covered as part of the same wider commercial footprint.
Frequently Asked Questions
Does a small commercial extension or change of use still need an ecological assessment, or is this only for major developments?
Ecological assessment isn't only for Schedule 1 or 2 EIA projects. A modest rear extension, car park expansion or change of use can still trigger a planning condition asking for ecological information if the site has trees, hedgerows, outbuildings or a pond nearby, because those features can support bats, nesting birds or amphibians regardless of project size. A short desktop-and-site-visit scoping check, which is free, is usually enough to tell a small commercial applicant whether anything further is needed, so it's worth asking before assuming a project is too minor to require it.
How long does an EcIA report or protected species survey stay valid before it needs repeating?
Ecological data has a shelf life because habitats and populations shift season to season. As a rough guide, habitat survey data is generally treated as current for around 12-18 months, and protected species survey data for a single season cycle - so a bat or great crested newt survey completed one year is normally still accepted the following year, but two survey seasons later a planning officer will typically ask for it to be refreshed. Building that into the project programme early avoids paying for the same survey twice.
What's the difference between an ecological impact assessment and the tree survey (BS5837) my architect has already asked for?
They cover overlapping but different ground. A BS5837 tree survey assesses individual trees - their condition, root protection areas, and how construction activity affects them - and is normally required whenever trees sit near a development boundary. An EcIA looks more broadly at habitats and protected species across the whole site, including trees as bat roost or nesting habitat rather than as individual specimens. Most commercial sites with trees need both; our NPTC Professional Tree Inspection qualification means the tree-specific assessment and the habitat survey can be coordinated in a single site visit rather than two separate ones.
What happens if ancient woodland or a veteran tree turns out to be on or next to my site?
Ancient woodland and veteran trees carry strong protection under Scottish planning policy and are treated as an irreplaceable habitat, so development directly affecting them is difficult to justify and buffer zones are usually required even for adjacent building work. In practice this means the layout may need redesigning around the constraint rather than removing it, and any application will need to show clear avoidance measures. Picking this up at the desktop and site-visit stage, before detailed design work is finalised, is far cheaper than discovering it after drawings are already submitted.
Can you give pre-application advice before I commission full surveys, so I know what to budget for?
Yes - the initial scoping visit is free and exists for that reason. We review the site, check statutory designations and habitat records, and give a written view on which surveys are actually likely to be needed, and which aren't, before any paid work is booked, so a budget and programme can be set with reasonable confidence rather than guessed at.
What do you need from me before you can give an accurate quote?
A site plan or boundary outline, a description of what's proposed - footprint, access changes, any tree or hedge removal - and the rough timeline for planning submission are normally enough for an initial quote. If there's an existing tree survey, drainage plan or previous ecological report for the site, sending that over speeds up the desktop stage and can reduce survey duplication.
What happens if my planning deadline falls outside the bat, bird or newt survey season?
This is one of the more common causes of commercial project delay, because protected species surveys follow biological activity periods rather than convenience - bat activity surveys run April to October, breeding bird surveys March to August, and great crested newt surveys mid-March to June. If a deadline falls outside these windows, options include submitting with a survey commitment condition, using off-season methods where the species allows it, or programming the application around the next available season. Flagging the deadline at first contact lets the survey calendar be planned around it rather than found out partway through a project.
Book Your Scoping Visit Before This Season's Survey Window Closes
Protected species surveys are locked to biological activity periods, not project convenience - miss the bat, bird or newt season and the report can be pushed back months, taking the planning application with it. Getting the free scoping visit booked now, while the current season is still open, is the single easiest way to keep a commercial development on its intended timeline.
