Portsmouth Clean Air Zone for motorhomes (2026)
For almost every motorhome owner, Portsmouth is free. It is a Class B Clean Air Zone — the lightest active charging zone in England — so cars, motorcycles, vans, and campervans or motorhomes up to 3.5 tonnes pay nothing, whatever their emissions class. The only exception is a motorhome over 3.5 tonnes that the DVLA classifies as a heavy goods vehicle, which pays £50/day if non-compliant (Euro 4 petrol or Euro 6 diesel). If that's you, check your plate on the gov.uk vehicle checker first.
Portsmouth is the easy one. Where Bath and Bradford make motorhome owners read the small print, Portsmouth's Class B scope leaves most rigs out of the charge entirely — vans and ≤3.5t campervans simply aren't in scope. The single thing worth a second look is whether your registration document classifies your vehicle as an HGV, because that is what decides the question, not the bare 3.5-tonne number. For the vast majority of readers, the rest of this page is reassurance rather than a bill.
Is my motorhome charged in Portsmouth?
Almost certainly not. Portsmouth charges only non-compliant buses, coaches, taxis, private-hire vehicles, and HGVs. Everything else — including private cars, motorcycles, vans, and campervans or motorhomes up to 3.5 tonnes — is outside the charge. If your rig sits at or under 3.5 tonnes, the zone is free for you and your engine's emissions class is irrelevant.
The one case where a motorhome owner pays is a rig over 3.5 tonnes that the DVLA has classified as a (Private) Heavy Goods Vehicle. That vehicle falls into the £50/day HGV tier and pays the charge if it is below the Euro 4 petrol or Euro 6 diesel threshold. The next section covers exactly how to check whether that applies to you.
What "Class B" actually means for motorhomes
England's Clean Air Zone framework defines four classes — A, B, C, and D — by which vehicle categories are charged. A is the lightest (buses, coaches, taxis only); D is the heaviest (everything, including private cars). Portsmouth is Class B, which adds HGVs and private-hire vehicles to the Class A list but stops there. Taxis and private-hire vehicles pay £10/day; HGVs pay £50/day. Cars, motorcycles, vans, and ≤3.5t campervans are not charged.
This is what makes Portsmouth unusual among the UK zones a touring motorhome is likely to meet. Bath and Bradford are Class C, where ≤3.5t campervans pay a daily charge; Birmingham is Class D, where even cars pay. Portsmouth sits below all of them. A ≤3.5t campervan that owes £9/day in Bath owes nothing in Portsmouth — same vehicle, same engine, different zone class.
The one exception: a motorhome over 3.5 tonnes
If your motorhome is over 3.5 tonnes, the question is not the weight on its own — it is how the DVLA has recorded the vehicle. Portsmouth charges by vehicle classification, and a rig logged as a (Private) Heavy Goods Vehicle falls into the £50/day HGV tier. That includes some heavier coachbuilt and A-class motorhomes on chassis re-plated above 3.5t for payload, where the registration body type reads as an HGV rather than a motor caravan.
There is no motorhome-specific reclassification route in Portsmouth. The published exemptions cover narrow cases — emergency, specialist, recovery, vintage-bus, and horse-transporter vehicles — and none of them reshape an ordinary touring motorhome's category. So the practical step for any over-3.5t owner is simply to confirm the facts: enter your registration in the official gov.uk vehicle checker, which tells you both your DVLA classification and whether you'd be charged in any English CAZ. Five minutes before you travel removes the guesswork.
Is your motorhome compliant?
Compliance only matters in Portsmouth if your vehicle is in a charged category in the first place — so for the over-3.5t HGV-classified case. The threshold is the same one used across the UK:
- Petrol engines: Euro 4 or newer (most petrol vehicles registered from January 2006 onward).
- Diesel engines: Euro 6 or newer (most diesel cars and light vans registered from September 2015 onward; later on some heavier motorhome chassis).
Fully electric and hydrogen vehicles are never charged, and motorcycles are out of scope entirely. The Euro class is recorded on Part I of your V5C log book — don't guess from the registration year, because some chassis lag the headline date by 18 to 24 months. But to repeat the headline: if your rig is at or under 3.5 tonnes, none of this changes anything — you are not charged in Portsmouth either way.
The boundary — a small zone in the south-west
The Portsmouth Clean Air Zone is a compact area of roughly 3 km² in the south-west of the city. It covers the city centre, Portsmouth Harbour, and the Portsea, Landport, and Somers Town areas. It is not the whole city, not all of Portsea Island, and it does not extend to Southsea or the seafront. Most of Portsmouth's residential streets and the eastern half of the island sit outside it entirely.
Because the zone is small and west-facing, a route that simply passes through or around Portsmouth often never enters it. The boundary and camera positions are documented on the council's own map at cleanerairportsmouth.co.uk/clean-air-zone-map. Check it before assuming a route is or isn't clean — the zone's position near the harbour is what makes the ferry case below worth a look.
Heading to the Continental or Isle of Wight ferries?
This is the one routing detail worth flagging. The zone sits in the same south-west corner of Portsmouth as the harbour, so drivers heading to the Continental Ferry Port or to the Isle of Wight ferry terminals can clip the edge of the zone on the approach — even though, for a ≤3.5t campervan, clipping it costs nothing.
If your rig is over 3.5 tonnes and HGV-classified, that approach is exactly where a charge could apply, so plan the last few miles deliberately. Check the council map against your ferry route, confirm your classification on the gov.uk checker, and you'll know before you arrive whether the harbour run touches the zone at all.
Camera enforcement and how the PCN works
Enforcement is by Automatic Number Plate Recognition (ANPR). Cameras photograph the plates of vehicles entering the zone; the system checks each plate against the DVLA database for the vehicle category and Euro class, and applies a charge only to the categories Class B covers. There is no in-vehicle device, no sticker, and no requirement to register in advance — and if your vehicle isn't chargeable, the cameras simply log you and let you through.
If you do owe the daily charge and don't pay it within the allowed window, the council issues a Penalty Charge Notice on top of the unpaid charge. The PCN amount is not stated on this page — contact Portsmouth City Council directly for the current figure, since it is subject to council review. The practical guidance: if you're in a chargeable vehicle, pay within the window and the PCN never arises.
Paying the charge
If you're in a chargeable category, pay via the gov.uk Drive in a Clean Air Zone service at gov.uk/clean-air-zones. The same service handles Portsmouth, Bath, Birmingham, Bristol, Sheffield, Tyneside, and every other England CAZ — one account, one payment flow, all zones.
The pay window runs from six days before travel to 11:59pm on the sixth day after. The charge is per calendar day, not per crossing, and the day runs midnight to midnight — so one entry or ten on the same date is a single charge. For the great majority of motorhome owners passing through Portsmouth, this section is moot: there's nothing to pay.
Which apps warn you before the boundary
Even when a zone is free for your rig, knowing where its boundary is still saves second-guessing — and for an over-3.5t HGV-classified motorhome, a warning before the line is the difference between a planned route and a £50 charge plus a possible PCN. The single most useful thing a motorhome sat nav can do is name the zone you're approaching and tell you whether your vehicle is in scope before you cross it.
Most consumer apps (Google Maps, Apple Maps, Waze) don't warn at all — they route you down toward the harbour and the ferry-port approaches the same as any car. The motorhome-aware apps that do warn are covered in the sibling matrix page: LEZ alert apps for motorhomes in Europe compares Sygic Truck & Camper, CoPilot Caravan, TomTom GO Navigation in Camper mode, and Rovee on coverage of UK CAZ zones and continental LEZ systems. Rovee carries the UK CAZ rule set in the same offline cache it uses for European LEZ boundaries, so warnings work whether you have signal or not.
Rovee names which UK Clean Air Zone you're approaching, which class applies, and what your rig owes — before you cross the boundary. For most motorhomes in Portsmouth that answer is "nothing", and knowing it without a detour is the point.

FAQ
Is my campervan charged in the Portsmouth Clean Air Zone?
No. Portsmouth is a Class B zone, which charges only non-compliant buses, coaches, taxis, private-hire vehicles, and HGVs. Cars, motorcycles, vans, and campervans or motorhomes up to 3.5 tonnes are not charged at all — regardless of their Euro emissions class. The only motorhome that can be charged is one over 3.5 tonnes that the DVLA classifies as a heavy goods vehicle, which pays £50/day if non-compliant.
Are cars charged in the Portsmouth Clean Air Zone?
No. Private cars are not charged in Portsmouth. The zone is Class B, the lightest of the active English charging zones — it applies only to buses, coaches, taxis, private-hire vehicles, and HGVs. A petrol or diesel car of any age pays nothing here, which is different from Birmingham, the one UK Class D zone where cars do pay.
My motorhome is over 3.5 tonnes — am I charged in Portsmouth?
Possibly. The charge does not hinge purely on the 3.5-tonne line; it hinges on how the DVLA classifies your vehicle. If your registration lists the body type as a (Private) Heavy Goods Vehicle, you fall in the £50/day HGV tier and pay that amount if your engine is below Euro 4 petrol or Euro 6 diesel. There is no motorhome-specific reclassification route in Portsmouth, so check your plate on the gov.uk vehicle checker before you travel rather than assuming.
Is my motorhome CAZ-compliant?
Petrol engines need to be Euro 4 or newer (roughly 2006 onward). Diesel engines need to be Euro 6 or newer (roughly September 2015 onward for cars and light vans; later for some heavier chassis). This is the same threshold as London ULEZ, Bath, and the Scottish LEZs, so a single emissions check applies across all of them. The Euro class is recorded on Part I of your V5C log book — but if your rig is under 3.5t, compliance does not matter in Portsmouth: you are not charged either way.
Does the Portsmouth zone cover the whole city?
No. The Portsmouth Clean Air Zone is a roughly 3 km² area in the south-west of the city — the city centre, Portsmouth Harbour, Portsea, Landport, and Somers Town. It does not cover all of Portsea Island, and it does not include Southsea or the seafront. Drivers routing to the Continental Ferry Port or the Isle of Wight ferries can clip the western edge of the zone, so check the council map if your route ends near the harbour.
When can I get Rovee?
