old petrol stations
Discussion
whats the deal with building on them? i assume no residential. being ex business you wouldnt't need a change of use for starting a business on the site? Do the tanks have to be filled in upon closing or when changing use and if this job is still to do does anyone have any ideas of cost?. I have been formulating a few plans but need to do some basework first.
My friends just going through this at the moment. Basically it would seem if you are going to be doing industrial on the site can you get away with just filing them. If you ever want to do residential you have to get them out. I seem to remember saying it was going to cost 25k to remove them and disposal but I'm not sure on that one.
As he has bought the land and doesn't know what the future may bring he's ripping them out now.
I can ask him more about it if you'd like but I might not see him now for a couple of months.

You'd need planning permission to change use to anything other than sale of fuel and vehicles - even an alternative commercial use.
And you would certainly need to clean up the site which is likely to require removal of the tanks - they're not going to be satisfactory to build over at the very least, and as part of your probably extensive environmental remediation, you're probably going to need to remove them in any case.
And environmental remediation is absolutely critical; it's costly and you are going to be compelled to do it probably both as a condition of any planning consent and in order to be able to sell the property in future.

Having built on the site of a petrol station I can tell you that there are various pre-build costs to take into consideration.
The Local Authority and Environmental Agency will be keen to know your proposals for decontaminating the site.
Our site dated back to the thirties and had been redundant for a number of years.
The presence of fuel in the soil was very evident when it was dug out.
I guess that a more modern forecourt would have some kind of capturing system for contaminants.

Last year we renovated a derelict carwash into the 21st century which had previously been a petrol station years before. We took more than 500 tons of contaminated soil off the site before replacing it with a thick layer of hardcore and about 18" of steel-meshed concrete.

Don't underestimate HOW costly - and the upfront survey costs associated with it can be significant too.HoHoHo said:

k me....... 
I had to remove 20 or so tons of contaminated soil from my commercial property some years ago and that cost an arm and a leg, your bill must have been HUGE!
Ours isn't even that huge a site. JCB loading onto a combination of 18-yarders (lorries) and 40-yarders (big skips). Small extra disposal cost in respect of the contamination, but all in all not too bad. From memory less than 10k. What surprised me was the extent of the contamination.k me.......

Mine was asbestos that had been dumped in the ground and the total cost for 2, 20 yard skip lorries (including labour) was near on £35k!Personally I wouldn't touch a site like that with a barge pole. You wouldn't really know the extent of any contamination until you started to clear it, I know the land will be cheap but it's still a big risk.
We converted an old factory (that used to be a school) into houses and discovered that a small diesel tank at the back had leaked, cue having to remove a load of earth...the only problem is that it was in what is now the back gardens of the houses, with no vehicle access so it was taken out one bucket at a time!

Looking into building on the site of an old petrol forecourt at the moment, just to give you the headlines. Yes redundant tanks are normally filled with foam or water. You will need to remove them before constructing over/around them. The cost for removal (1960's ish constructed petrol station) will be about £5k a tank. The excavated material around the forecourt will be heavily contaminated, allow for all of it to be contaminated, thus an increased cost to dispose of.

I was researching an indea last year and found that some self-build mortgages wouldn't lend for ex-petrol stations. Not sure how widespread that is.
Thats because the chance of contamination is very high.We have built on a number of petrol stations over the years and generally the cost to clean up is mega. It used to be circa £50k to remove each tank, they you have to isolate and remove the hydrocarbons that will have leaked, then you have to import engineered fill. The sites are typically small, so these costs add a big lump tp the build.
I prefer to build on old pub sites. It was much easier until ACV.
Reading this makes me worry somewhat....
Our property is half old stable and coaching house (dating to 1860) but from about 1920 to early 1960 it was used as a service station including a couple of petrol pumps. I am not sure what happened to the site when it was converted to a couple of residential properties in the late 1960s. I am told the tanks are still buried under our front driveway and there are a couple of 'vents' coming from the tanks and appearing at our front boundary wall.
Probably nothing too much to worry about - but my curiosity of the contaminants in the ground is high. What could possibly happen? We are towards the top of a hill so I imagine rainwater may have taken away most contaminants over the years?

Hydrocarbons can be quite mobile, especially where the water table is high.
The very worst is that contamination migrates to adjoining properties and or ann aquifer. You would be esponsible for the entire clean up under the "Polluter Pays" laws. This is why developers are wary of ex petrol stations
Thats worst case, best case is that all is ok. Dont grow carots
