Questions from Ayrshire houses off the beaten track

Your oil tank needs a bund in Scotland if it holds more than 2,500 litres, or if a smaller house tank sits near water, an open drain, a spring or borehole, or another spill hazard.

An oil tank closer than 1.8m to the house is allowed in Scotland only with extra fire protection: a non-combustible base, non-combustible eaves nearby and, in most cases, a fire barrier between tank and house.

If heating oil leaks, keep people and pets away, keep oil out of drains and burns, call SEPA straight away if it could reach water, then ring your insurer.

A plastic oil tank lasts around 20 years, the expected working life OFTEC gives for fuel tanks, though the risk of failure rises with age and a yearly inspection tells you more than the date.

To help stop heating oil being stolen, lock or cage the tank, light it, fit a level alarm, keep it in view of the house, and watch the gauge so a sudden drop shows quickly.

An OFTEC-registered technician should service the oil boiler and tank, at least once a year or as the maker's instructions say, and the service should include the tank and its pipework.

You probably have a private water supply if your water comes from a spring, well, borehole, burn or loch rather than the Scottish Water mains, and your council tax bill carries no water charge.

Your council's environmental health team tests a private water supply: at least once a year for regulated supplies, and on request for small single-house supplies, which may carry a fee.

Yes, there is a grant to improve a private water supply in Scotland: up to £800 per property, paid through your council for work such as treatment, new tanks or replacing lead pipes (checked November 2026).

Spring water usually turns brown after heavy rain because the rain washes peaty organic matter from the hill into the source, and that colour can stop UV treatment working properly.

Yes, most private supplies need a UV unit or another form of disinfection, because mygov.scot says a private supply will always need disinfection to kill harmful bacteria, and UV only works on clear, pre-filtered water.

Pressure on a private supply usually keeps dropping because a filter cartridge is clogging, the source runs low in dry weather, or the pump and pressure vessel are struggling.

Yes, you need to register your septic tank discharge with SEPA; registrations held on 31 October 2025 carried over automatically to the new rules, and an unregistered tank needs an application now.

A septic tank should be emptied, or de-sludged, at least once a year according to SEPA, and more often if the tank is small for the household or the maker says so.

A soakaway is usually failing when the ground over it stays wet or pools with sewage, there is a smell outside, the grass there is unusually lush, or the drains in the house slow and gurgle.

With a septic tank, only toilet waste, toilet paper and household washing water should go down the drain; fats, oils, chemicals, wipes and rainwater all cause trouble.

A septic tank and a treatment plant differ mainly in how well they clean sewage: a septic tank settles solids for basic treatment, while a treatment plant uses biological treatment to a much higher standard.

When you sell a house with a septic tank, the SEPA registration should be transferred to the buyer, so find the registration, emptying receipts and any shared-tank arrangements before the house goes on the market.

A heat pump can work in an old stone cottage, but only when it is designed for that house: sized from a proper heat calculation, run at low water temperatures, with the loft and draughts sorted first.

Swapping an oil boiler for a heat pump makes most sense when the boiler is near the end of its life, the house is insulated, and you can line up the Home Energy Scotland grant before any work starts.

LPG or oil can both heat a house off the gas grid well; the better choice depends on where a tank can safely sit, who services it locally, and whether a heat pump would suit you better.

Yes, you can keep using a wood-burning stove in an existing Scottish home: the Scottish Government says there is no blanket ban, though it should be swept, serviced and paired with a carbon monoxide alarm.

Yes, every Scottish home with a carbon-fuelled appliance such as an oil or LPG boiler, open fire or wood burner must have a carbon monoxide alarm in the same room as that appliance.

One radiator stays cold when the rest are hot usually because of trapped air (cold at the top), sludge (cold at the bottom), or a stuck valve pin (cold all over).

To stop pipes freezing in an exposed house, lag every pipe in cold spaces, keep some heat on day and night, cut draughts, and know where your stopcock is before the first hard frost.

If a pipe has frozen, turn off the stopcock, open the nearest cold tap, check the pipe for splits, then thaw it slowly with hot-water bottles or warm cloths and never a flame.

When a pipe bursts, turn off the stopcock straight away, keep away from any electrics the water has reached, switch off the boiler and water heater, then open the taps to drain the system.

The stopcock in an old farmhouse is usually where the water pipe comes into the house, often under the kitchen sink, but in older and extended houses it can be in a porch, under a floor or in an outbuilding.

The water pipe to your house is split in two: Scottish Water owns the communication pipe in the street up to the boundary stopcock, and the supply pipe from there into the house is usually yours.

To know if you still have lead pipes, look at the pipe coming into the house under the kitchen sink: lead is dull grey, scratches easily to shiny silver, and may have bulges at the joints.

A house by the sea is often damp because moist air meets cold walls and windows, wind-driven rain soaks exposed gables, and salts in old stonework draw in moisture, especially in rooms heated only now and then.

Condensation or rising damp can look alike, but condensation appears on cold surfaces and comes and goes with cooking, washing and cold weather, while damp at the base of an old wall usually comes from poor ground drainage.

Salt air can damage a heat pump's outdoor unit, because salt spray and damp onshore wind speed up corrosion of its metal parts, so coastal models, careful siting and regular checks matter near the shore.

To look after a cottage left empty over winter, keep low, steady heat on a frost or holiday setting, have someone check it regularly, know where the stopcock is, and keep damp in check.

Home Energy Scotland gives free, impartial advice on heating and energy saving, and runs the Home Energy Scotland Grant and Loan for heat pumps, insulation and other improvements to Scottish homes.

Yes, there is extra grant help for rural homes: as of November 2026 Home Energy Scotland adds £1,500 to both its heating and energy efficiency grants for eligible rural and island homes.

Most heating changes in a Scottish house do not need a building warrant, but a new oil tank over 90 litres, work on a chimney, flue-pipe or hearth, and large boilers fall outside the exemption.

To choose a heating engineer or plumber, first match their registration to your fuel (OFTEC for oil, Gas Safe for LPG, HETAS for stoves, MCS for heat pumps), then compare written quotes and check them through official trader schemes.
