Newt, Reptile & Mammal Fencing
installed to your ecologist’s spec
Protected species exclusion fencing for highways, rail, utilities and development sites — installed to the ecological method statement, with the records your ecologist and planning officer need.
Exclusion fencing that survives the audit
When a scheme has great crested newts, reptiles, badgers or other protected species on it, the mitigation fencing is not a fencing job with an ecology label on it — it is a compliance item. It has to go in on the line the ecologist specified, to the detail they specified, before the works window opens, and it has to be evidenced. Get it wrong and the scheme stops.
GGT installs newt and amphibian barrier fencing, reptile fencing, badger and mammal exclusion fencing, and permanent species fencing across highways, rail, utilities and development sites. We work to your ecologist’s method statement — the licence and the ecological decisions sit with them; the installation, the line, the dig-in depth, the overhang, the pitfall traps and the integrity of the barrier are ours. We photograph as we go and hand over as-built records, so when the ecologist or the planning officer asks for evidence, it exists.
We are registered to National Highways Sector Scheme 18, the quality scheme covering landscape and ecology works on the highways network, and hold CHAS, Constructionline Gold, Achilles UVDB and ISO 9001 with £10 million public liability cover. On the M55 we installed mammal and exclusion fencing to ecological specification with the compliance records the ecology team required — see the M55 mammal fencing project.

Installed right, evidenced properly
We read the ecology first
Before we price anything we read the ecological method statement and the constraints — fence type, dig-in depth, overhang, trap spacing, the line on the drawing and the date the barrier has to be functional by.
Line prepared, then installed
The line is cleared and prepared so the barrier sits tight to the ground with no gaps, dug in to the specified depth and tensioned properly. A newt fence with a gap under it is not a newt fence.
Photographed as we go
Progress and completion photographs, fence line records and as-built information are captured during installation — not reconstructed afterwards — and handed to your ecologist.
Maintained, then removed
We inspect and repair the fence line through the trapping or works period, then remove it and reinstate the ground when the ecologist signs off that it is no longer required.
Covering Lancashire & the wider North West
We deliver ecological fencing right across the North West. Choose your area, or see everywhere we cover.
Ecological Fencing — frequently asked questions
Do you hold the protected species licence?
No — and no fencing contractor should claim to. The licence sits with your ecologist or the licensed ecologist named on the scheme, and the ecological decisions are theirs. Our job is to install the mitigation exactly as their method statement specifies, to the right line, depth and detail, and to evidence it. We work alongside ecologists on most of these schemes and are used to their reporting requirements.
What is NHSS 18 and why does it matter here?
National Highways Sector Scheme 18 is the sector-specific quality management scheme for landscape and ecology works on the highways network. It sits on top of ISO 9001 and is a requirement for contractors delivering this type of work for National Highways and its supply chain. In practice it means our processes for ecological works have been independently audited — which is exactly the assurance a principal contractor needs at pre-qualification.
Can you install to the Natural England and CIRIA guidance?
Yes. Amphibian and reptile exclusion fencing is normally specified against Natural England’s great crested newt mitigation guidelines and the CIRIA wildlife fencing design guide, and that is what we build to. If your ecologist has specified a particular product, dig-in depth, overhang or trap regime, we install to that specification rather than a generic detail.
How quickly can you mobilise?
Ecological fencing is usually driven by a hard date — the barrier has to be functional before trapping starts or before the works window opens. Tell us the date at enquiry stage and we will tell you honestly whether we can hit it. For schemes already in programme we would rather book the slot early than promise something tight and let the ecology programme slip.
Do you work outside the North West?
Our base and the bulk of our work is the North West, but protected species fencing is a specialist package and we travel for it — particularly on highways and infrastructure schemes where we are already in the supply chain. Tell us where the site is and we will tell you whether it works.
Can you do the vegetation clearance and the fencing together?
Yes, and it is usually cheaper and faster that way. Fence lines almost always need stripping and clearing before installation, and there are often ecology-sensitive clearance constraints on the wider site. We handle vegetation clearance and land clearance in-house, so one contractor clears the line, installs the barrier and reinstates afterwards.
One contractor for the whole site
Most clients use us for more than one service. Because it's the same crew and one point of contact, the work joins up.
