Carmarthen to the M25.
Plus the West Midlands.

Japanese knotweed is endemic across South and West Wales — a legacy of coal-mining, copper smelting and unmanaged riparian corridors along the Taff, Usk, Tawe and Tywi. Our Cardiff and Swansea crews cover every CF, NP and SA postcode in the region.

The Wye and Monnow are SAC-protected rivers — patient, NRW-compliant herbicide programmes are almost always the right call here. We work the Welsh borders from Chepstow up to Monmouth and across into the Forest of Dean fringe.

The Avon valley, Bath's hillside terraces, the Bristol-to-Bath railway path, the Somerset Levels and the Exe corridor make the South West some of the most knotweed-dense ground in England. Our Bristol crew covers BS, BA, TA, BS, EX, DT and SP postcodes daily.

The Thames Valley sits on a knotweed-dense stretch of the M4. Riparian growth along the Thames and Kennet — and the network of disused gravel pits between Reading and Maidenhead — is among the worst in southern England. Our Reading crew covers SN, RG, SL, OX and HP postcodes.

• Wokingham
• Maidenhead

Boroughs along the Thames, the Lea Valley and disused rail land carry the worst knotweed loads in London. Garden boundaries backing onto these features are the most common survey trigger across N, E, SE, SW and W postcodes.

• London

Birmingham is the northern anchor of our service map — the natural extension of the M4 corridor up the M5 and M42. Our Birmingham crew covers the whole West Midlands conurbation (B, CV, WV and DY postcodes), with daily routes through Solihull, Coventry, Wolverhampton and the Black Country.

Gloucester, Cheltenham, Stroud and Worcester — the Severn floodplain, the Five Valleys and the Worcester & Birmingham Canal form the bridge between the M4 corridor and the West Midlands, and round out our regular service patch on the way up to Birmingham.
