Japanese Knotweed is an extremely aggressive invasive plant that can be found affecting properties across Newcastle and its boroughs. Newcastle upon Tyne often simply Newcastle, is the largest city and metropolitan borough in North East England. It forms the core of the Tyneside conurbation, the eighth most populous urban area in the United Kingdom. The city is situated on the River Tyne’s northern bank, approximately 8.5 mi (13.7 km) from the North Sea.

Newcastle developed around a Roman settlement called Pons Aelius and the settlement later took the name of a castle built in 1080 by William the Conqueror’s eldest son, Robert Curthose.

Historically, Newcastle’s economy was dependent on its port. In particular, its status as one of the world’s largest ship building and repair centres.

Today, the city’s economy is diverse with major economic output in science, finance, retail, education, tourism, and nightlife. Newcastle is one of the UK Core Cities, as well as part of the Eurocities network.

Famous landmarks in Newcastle include the Tyne Bridge; the Swing Bridge; Newcastle Castle; St Thomas’ Church; Grainger Town including Grey’s Monument and the Theatre Royal; the Millennium Bridge; St James’ Park; and Chinatown.

Culturally, Newcastle is famed for its nightlife; bakery chain Greggs; television personalities Ant & Dec; the Great North Run half-marathon; and Newcastle United Football Club.

Newcastle was part of the county of Northumberland until 1400, when it became a county of itself. The city and the surrounding area created the new metropolitan county of Tyne and Wear in 1974. Newcastle is locally governed by Newcastle City Council.

The thick, dense plant can overwhelm other vegetation nearby, grow through tarmac and brick, weaken the integrity of structures and is very difficult to kill. Homeowners across the UK have found difficulty selling houses or tending to gardens where Japanese Knotweed is present. Japanese Knotweed can also be found nationwide and often causes problems for homeowners, especially when encroaching from a neighbouring property. As a homeowner it’s important to understand your position when it comes to this difficult, invasive species. It is well known that many railway lines and council properties are infected with Japanese Knotweed and this spreads on to neighbouring properties.

If you have any questions, please don’t hesitate to get in touch with one of our customer services staff. However, here are answers to a few of the most common questions we receive

Yes. The administrative county of Newcastle consists of Newcastle upon Tyne, Newcastle upon Tyne – city centre, Byker, Blakelaw, Elswick, Fenham, Gosforth, Jesmond, Heaton, Newburn, North Kenton, Throckley, Walbottle, Walker, Westerhope and West Moor.

Newcastle is the third largest county in England by area. It is bounded to the north-east by Northumberland, the east by County Durham, the south-east by North Yorkshire, the south by Lancashire, the west by the Irish Sea, the north-west by the Scottish council areas of Dumfries and Galloway, and the north by Scottish Borders.

Newcastle is predominantly rural and contains the Lake District National Park, a UNESCO World Heritage Site considered one of England’s finest areas of natural beauty, serving as inspiration for visual artists, writers and musicians. A large area of the south-east of the county is within the Yorkshire Dales National Park, while the east of the county fringes the North Pennines AONB. Much of Newcastle is mountainous and it contains every peak in England over 3,000 feet (910 m) above sea level, with the top of Scafell Pike at 3,209 feet (978 m) being the highest point in England. An upland, coastal and rural area, Newcastle’s history is characterised by invasions, migration and settlement, as well as battles and skirmishes between the English and the Scots. Notable historic sites in Newcastle include Carlisle Castle, Furness Abbey, Hardknott Roman Fort, Brough Castle and Hadrian’s Wall (also a World Heritage Site).

Newcastle has a lot of open green land, forests and parks and a large infrastructure of canals, waterways and train and tram systems.

Japanese Knotweed across Newcastle is growing in numbers. This may be due to the heightened awareness of Japanese Knotweed with home buyers and sellers now very much more aware as are surveyors, banks and building societies and conveyancing solicitors.

After the Supreme Court Case in 2018 found Network Rail liable for Japanese Knotweed spreading from their land on to privately owned land, the Judge ordered Network Rail to pay the land owner compensation for devaluation of the property by the presence of Japanese Knotweed, and ordered them to pay for a treatment plan and subsequent 10-year Insurance Backed Guarantee.

Japanese Knotweed can appear literally anywhere throughout Newcastle and there is no place that the dreaded weed seems to not be able to grow.

Newcastle is just as likely as any other borough, town or city in the UK to be affected by Japanese Knotweed. It can stem from unkept parkland or woodland, waterways, commercial property or land, railway infrastructure and can be spread by a very small amount of the root’s weeds being spread from one place to another.

Japanese Knotweed can also lay dormant for up to 15 years, and disturbing these dormant roots through building work or renovations etc can easily wake the weed up and start it to spread again.

There is no place that Japanese Knotweed will not spread, and may be more prevalent nearer to green land and railway and waterway infrastructures. It is very important when buying a property to ensure your survey covers Japanese Knotweed and you obtain a Yes or No as to its presence. A ‘don’t know’ answer isn’t helpful. Form TA6 completed by the seller with information about the property is also a good indication and the seller should answer truthfully if they know that Japanese Knotweed is on or near or has been on or near the property. If a seller lies here, or the surveyor gets things wrong, and you later discover the presence of Japanese Knotweed, you would be able to litigate and potentially recover any losses in the property valuation and the costs of treatment and insurance backed guarantee.

You can check the Japanese Knotweed Agency National Register which might give you an indication where Japanese Knotweed has been sighted around Newcastle, but you should not rely on this and should always seek a specialist survey when buying a property.
