Heating Oil Supply Pipe Run

[Barnman]

What are the regulations regarding running an oil supply pipe from a tank to the boiler. Does it have to enter the house above ground with a fire valve, or can a fire valve be fitted on the inside and the pipe enter under ground.

Also are there regulations regarding how far it should be from a water supply pipe.

Pipe should enter from above ground, Fire Valve should be fitted before it enters the property, underground pipe should be at least 600mm deep, any joints should be within an inspection chamber (not buried)
I'm not aware of any regulations regarding proximity to other underground services

Thanks

Could the pipe enter the building and then run under the floor screed and insulation to where it rises near the boiler? It would be around 20cm (maybe more) below the top of the screed. If this is OK would it need to be in conduit?

Thanks but that is not a lot of use. Can anybody else offer any more constructive advice. I will be employing a plumber and heating engineer but I am trying to get all the service pipes in before I lay patios and turf.

You have been given the correct advice.

The fire valve must be located outside.

Valves are made with up to 20m capilliaries, so I suppose you could fit a duct to accommodate it. Separate from the oil supply.

Bear in mind that they do sometimes need replacing, so the duct would need to be straight, and of a size to enable insertion and extraction.

A classic case of the OP being told that the job can't be bodged then?
