Joel Harrison has lived in a 3.5-tonne motorhome since 2021. This is the piece he wishes someone had handed him at the Glasgow city boundary.
The first letter said £60. I paid it and thought that was that. The second said £120. The third said £240. The fourth said £480, and it arrived on a Tuesday, in a stack, because Glasgow's cameras had photographed me four days running and the penalty notices had caught up with each other in the post.
Nobody in my club had heard of the rule. It is on mygov.scot in black and white, and it has been since the four Scottish cities switched their low emission zones on. In England a clean air zone is a charge: you drive in, you pay the day rate, you carry on. In Scotland it is not a charge. It is a ban, with a fine. A non-compliant vehicle in Glasgow, Edinburgh, Dundee or Aberdeen gets a £60 penalty, and every time you re-enter within 90 days of the last one, it doubles. The cap is £480 for a vehicle under 3.5 tonnes and £960 for one over. There is no day pass, no online payment that makes it legal, no "just this once".
Most motorhomes on UK roads are Euro 5 diesels. That is the problem. Euro 6 diesel is the line, and Euro 6 only became compulsory on new vans in September 2016, so anything built before then is on the wrong side of it. If yours is a 2015 Ducato, a 2014 Sprinter, a 2013 Transit, you are what these zones were built to catch.
What I have learned since, in order of how much it would have saved me
1. Check the Euro standard on your V5C, not the badge. Field V.9 in the "Emissions" section, or the "Euro status" line if your V5C is old enough to have one. If it is blank, the zone checkers work off the date of first registration, which for a Euro 5 van built in 2016 and registered late can put you the wrong side of a line you should have cleared. You can send the manufacturer's Certificate of Conformity to the zone operator and get reclassified. Nobody tells you this.
2. In England, your V5C body type decides whether you pay £9 or £100. Under 3.5 tonnes the English zones charge a van under a tenner a day (Bath £9, Birmingham £8, Bristol £9, Sheffield £10, Bradford £9, Portsmouth nothing). Over 3.5 tonnes you are a lorry at £50 to £100 a day, unless your V5C says "motor caravan", in which case Bath will give you a £9 rate on application, Sheffield sells a £10 per-trip permit, Bradford exempts you automatically and Tyneside has an exemption you apply for. A converted van still registered as a panel van gets none of that. If you have been paying the lorry rate in a big coachbuilt, you may have been overpaying by a factor of ten.
3. London is two zones stacked on top of each other, and the heavy one is the trap. Under 3.5 tonnes you are in the ULEZ: £12.50 a day for a Euro 5 diesel, every borough, every day but Christmas. Over 3.5 tonnes you fall into the older LEZ instead, which wants Euro VI and charges £100 a day for Euro IV or V and £300 for anything older. A 3,850kg Euro 5 coachbuilt going to see the grandchildren in Bromley for a long weekend is looking at £300 before it has parked, and the penalty for not paying is in the hundreds on top.
4. The 90-day doubling clock in Scotland resets. If you paid a £60 penalty in Edinburgh in March and go back in July, you are back to £60. Time it, or just do not go in. Every one of the four Scottish zones is small. Glasgow's is the city centre inside the M8. Aberdeen's is the centre. You can park a motorhome on the edge and walk in, which is what I do now.
5. If you get a penalty, you have 28 days and a real chance. Wrong Euro classification, sign obscured, vehicle sold, first offence in a zone with no signage on your approach road: all of those succeed regularly. The appeal route is the operator first, then the independent adjudicator. It costs nothing. Most people just pay.
The bit nobody puts in one place
The zones are only the bit that got me. What I actually wanted, and could not find, was a single document that answered the other questions I had been guessing at for five years: where in the UK you can actually park a motorhome overnight without a knock on the door, what the fine is if you get it wrong, what the 3.5-tonne line does to your licence and your payload, and what every toll and tax figure is this year rather than in 2019 when the forum post was written.
So over the winter I wrote it. Every council overnight rule in England, Scotland and Wales that changed in the last eighteen months. The Highland pass, the Forestry and Land Scotland Stay the Night scheme, Loch Lomond's permit system and the byelaw review that closed this week. Scarborough and Whitby's permanent ban from March. Cornwall's ten-car-park plan. Gwynedd's aires. Every English clean air zone with the motorhome discount in a table. The Scottish doubling sequence, worked out. The London stack. The payload maths and the DVSA penalties. The 2026 tolls (Tyne, Mersey and Humber all changed this year) and the April VED figures.
It is a guide, an Excel calculator that tells you what your specific van pays in every zone from three inputs, and a set of cab cards to print and keep in the door pocket. If it saves you one £480 letter it has paid for itself sixteen times over. It's here:

If you only take one thing from this page: check your V5C tonight, and if it says Euro 5, do not drive into Glasgow.
