Bed Bug Heat Treatment in Gwent
Gwent covers Newport, Torfaen, Blaenau Gwent and Monmouthshire: the city of Newport and Caerleon, Cwmbran and Pontypool up to Blaenavon, the Ebbw Fach and Sirhowy valleys at Ebbw Vale, Abertillery and Tredegar, and rural Monmouthshire from Abergavenny and Monmouth to Usk, Chepstow and Caldicot on the Severn. It is the largest Welsh region by area, so hubs are spread to keep travel practical.

Areas we cover
Gwent districts, service areas and postcodes
Coverage grouped by authorities, with service areas, postcode districts and boundary detail from the verified geographic registry. A geographic match is not the same as confirmed service availability.
Blaenau Gwent, Torfaen, Newport and Monmouthshire are four separate unitary authorities. Gwent is a CoverageMaps Pro service-region name, not a current council: the historic county was abolished in 1996. Each table states the authority an address sits in.

Property and access
What affects a Gwent heat treatment
The practical detail of the building changes the plan far more than the region does.
City terraces and conversions
Pillgwenlly, Maindee and Newport city centre hold dense terraces and subdivided buildings with shared access that are assessed together.
New-town housing
Cwmbran was built as a new town and holds estate housing in Croesyceiliog, Fairwater, Greenmeadow and Thornhill where whole-property treatment is normally planned.
Valley terraces
The Ebbw Fach, Sirhowy and Afon Lwyd valleys hold dense stone terraces from the industrial period, often with adjoining roof and floor voids that are checked as part of a treatment.
Estate and commuter housing
Ringland, Bettws, Rogerstone, Caldicot and Magor hold estate housing and Severn-crossing commuter developments where a discreet, planned visit is usually preferred.
Rural and market-town property
Abergavenny, Monmouth, Usk and Chepstow hold older stone cottages, farmhouses and market-town flats where the building's construction shapes the treatment plan.
Guest and holiday accommodation
The Wye Valley, Black Mountains and Blaenavon World Heritage Site carry guest houses, holiday lets and camping with seasonal changeover that work is planned around.
The treatment
How the treatment itself works
The method does not change between towns. These are the authoritative pages.

Guarantee
Six-month guarantee
6-Month Guarantee
Our six-month guarantee provides additional reassurance following qualifying treatments. Full guarantee conditions are provided before treatment and form part of the customer agreement.
Terms and conditions apply. The guarantee is conditional, and known operational conditions include matters such as:
- Bed bug activity originating from an adjoining property
- Reintroduction following treatment
- Activity outside the agreed treatment scope
- Failure to comply with agreed preparation requirements
- Failure to follow relevant aftercare requirements
Full conditions are provided in writing before treatment. This page explains the principle of the guarantee only — it is not the customer agreement.
Guarantee InformationEvidence
Gwent treatment evidence
We do not publish invented local case studies. Anonymised Gwent evidence will appear here once genuine treatment records have been through our approval and anonymisation process.
Questions
Gwent questions
- Is Gwent a council?
- No. Gwent is the CoverageMaps Pro service-region name for four separate unitary authorities: Blaenau Gwent, Torfaen, Newport and Monmouthshire.
- Is this the Newport in Wales?
- Yes. This region covers the city of Newport in South Wales (Casnewydd), from Rogerstone and Bassaleg to Llanwern and the Gwent Levels. Newport in Shropshire and Newport in Pembrokeshire are separate places with their own hubs.
- Which hub covers the Heads of the Valleys?
- Ebbw Vale covers Ebbw Vale, Beaufort and Rassau; Tredegar covers the Sirhowy valley; Brynmawr covers Blaina, Nantyglo and the Clydach gorge; Abertillery covers the Ebbw Fach and Llanhilleth.
- Is rural Monmouthshire covered?
- Yes. Abergavenny, Monmouth, Usk, Chepstow and Caldicot cover the county's villages, the Wye Valley and the Severn shore.
- Can a terrace be treated on its own?
- Yes. The adjoining properties are considered because bed bugs move through shared voids, and neighbours can be checked with their agreement.
