Below Tolerable Standard Homes | Scotland Property Auction
Yes, you can sell a house that is "below the tolerable standard" (BTS) in Scotland. It is not illegal to sell one, and it is not illegal to buy one. But the label changes who can buy it, how it is financed and what the council can do, which is why many owners find an auction with a 28-day completion is the cleanest route. This guide explains what the standard is, how a property ends up below it, and exactly what to do next.
- The tolerable standard comes from section 86 of the Housing (Scotland) Act 1987, as amended, and is described by the Scottish Government as condemnatory – a home below it is considered unacceptable to live in.
- Living in a BTS home is not itself illegal; occupying a home under a closing or demolition order is.
- Most high-street mortgage lenders will not lend against a BTS property, so the buyer pool is usually cash buyers, investors and developers.
- Your Home Report must be honest. A serious defect will normally show up in the condition ratings and the surveyor's comments.
- Auction suits BTS homes because buyers expect the condition, accept the legal pack as-is and can complete in 28 days.
What does "below the tolerable standard" actually mean in Scotland?
The tolerable standard is a basic, minimum test for houses in Scotland. It is set out in section 86 of the Housing (Scotland) Act 1987 and has been updated since, most recently to cover interlinked fire and smoke alarms and carbon monoxide alarms. It is not a measure of how nice a home is. A tired, dated house can pass easily. A house is "below tolerable standard" only when it fails one or more of the basic criteria.
Scottish Government guidance sets out what a house must have. In summary, it must:
- be structurally stable;
- be substantially free from rising or penetrating damp;
- have adequate natural and artificial lighting, ventilation and heating;
- have adequate thermal insulation;
- have an adequate piped supply of wholesome water inside the house;
- have a sink with hot and cold water inside the house;
- have a toilet for the occupants' exclusive use, suitably located inside the house;
- have a fixed bath or shower and a wash-hand basin, each with hot and cold water;
- have an effective system for draining and disposing of foul and surface water;
- where electricity is supplied, meet the electrical installation requirements;
- have satisfactory cooking facilities;
- have satisfactory access to external doors and outbuildings; and
- have an interlinked fire and smoke alarm system and adequate carbon monoxide alarms.
If a home fails any one of these, it can be classed as BTS. The Scottish Government describes the standard as condemnatory, meaning a house that fails it is considered unacceptable for people to live in.

How does a house end up below the tolerable standard?
In my experience it is rarely one dramatic event. It is usually years of small things that nobody had the money, energy or time to fix. The common routes are:
- Long-term neglect – a roof leaking for years leads to penetrating damp, which leads to rot and eventually structural concerns.
- An empty home – heating off, pipes damaged, vandalism or break-ins. See our guide to selling an empty home at auction.
- An inherited property that nobody lived in for a long time. Our article on inherited property at auction covers the executor side.
- Missing basic amenities in very old houses – for example an outside toilet or no proper hot water supply.
- Damage from fire, flood or subsidence that has not been repaired.
- Failed alarm or electrical requirements – often fixable quickly, but still technically a failure.
Who decides a property is BTS?
The local council. Councils have a statutory duty and specific powers to deal with BTS housing. Environmental health officers can inspect when someone complains, when an owner or occupier asks, when an earlier finding means a re-inspection is needed, or when an officer thinks it necessary. Your own surveyor may also describe a defect that would fail the standard in your Home Report, but the formal classification is a council decision.
What can the council do about a BTS house?
Councils generally start by expecting the owner to bring the property up to standard within a reasonable time. In the most serious cases they can go further. According to council guidance, the options include requiring repairs, and, in extreme cases, closing or demolishing the property. The key points for a seller are:
| Council action | What it means | Effect on a sale |
|---|---|---|
| Informal request to repair | Owner asked to fix the failing items | Sale possible; disclose in full |
| Formal notice requiring work | Legal obligation to carry out specified work | Obligation can pass to the buyer; see statutory notices |
| Closing order | Property may not be occupied | Sale possible, but buyer cannot move in until it is lifted |
| Demolition order | Property to be demolished | Very specialist buyers only |
One point worth stressing: living in a BTS home is not illegal, but occupying a property subject to a closing or demolition order is. Some councils also point out that a council tax exemption may apply while occupation is prohibited.
Councils also do not generally offer grants to improve homes below the tolerable standard, so owners should not assume funding will arrive to rescue the situation.
Can you legally sell a BTS house in Scotland?
Yes. There is no general legal bar on selling a BTS property. What matters is that you do not mislead anyone. Under Scots law the seller must provide a Home Report in most cases (see Home Reports and auction sales for the exemptions), and the surveyor's findings will be in front of every buyer. If you know about a council notice or a defect, say so. Concealing it risks a claim later and delays completion when your solicitor and the buyer's solicitor find it anyway.
If the property is under a closing order, your solicitor needs to check the order is correctly recorded and explain to the buyer what it means in practice. For related issues see our Scottish property terms glossary.
Will a mortgage lender lend on a BTS property?
Generally no. Lenders want security that is habitable and insurable, and a BTS property is neither. That means the usual first-time-buyer and family buyer pool largely disappears. Buyers who can still proceed typically include:
- Cash buyers – investors, developers and tradespeople.
- Bridging finance users – who buy, fix, then refinance. See our guide to auction finance in Scotland.
- Specialist lenders – willing to lend on refurbishment projects in some circumstances.
This is the same buyer pool as for other unmortgageable homes, and it is why the open market so often stalls on these properties: buyers fall through at the lender's valuation, and the seller starts again.
- Buyers expect poor condition, so surprises do not derail the sale.
- Cash and bridging buyers can commit with a 10% deposit and complete in 28 days.
- No chain and no mortgage valuation to fail.
- Certainty of a binding sale once the hammer falls or the offer is accepted.
- The price will reflect the repairs needed; expect a discount to a fixed-up equivalent.
- You must still disclose every known defect and notice.
- A closing or demolition order narrows the buyer pool further.
- Any outstanding council costs must be dealt with in the sale.
Should you repair it first or sell as it is?
This is the question every owner asks, and the honest answer is: it depends on the cost, the time and your finances. Compare the two routes:
| Factor | Repair, then sell | Sell as seen |
|---|---|---|
| Upfront cost | You pay for all works | None |
| Time | Months, with contractors and warrants | Weeks |
| Buyer pool | Wider, including mortgage buyers | Cash, bridging and investors |
| Risk | Costs overrun; sale price may not recover them | Lower price, but certain |
| Best for | Small, cheap fixes (alarms, a boiler) | Structural, damp, rot or major amenity issues |
A sensible rule of thumb: fix cheap, quick failures that are easy to evidence (for example smoke and carbon monoxide alarms), and sell the bigger problems as seen. Get at least two quotes before deciding, and keep paperwork for any work done. If building work needs a warrant, see our article on selling with no building warrant.
How does the Home Report treat a BTS property?
The Home Report includes a Single Survey with condition ratings. Category 3 means urgent repairs are needed and category 2 means repairs or replacement are required but not yet urgent. A property with a serious failing will often attract category 3 ratings on the relevant elements, and the surveyor may state that the property is not suitable for mortgage lending without repairs. Read our explanation of the Home Report category 3 rating to see how this plays out.
Do not argue with the surveyor to soften the report. Buyers at auction price the risk themselves, and an honest report with clear photos tends to bring more serious bidders, not fewer.
What is the best way to sell a BTS house in Scotland?
There are three realistic routes:
- Open market with an estate agent – works only if the failing is minor or the buyer is a cash investor. Long timescales and fall-throughs are common.
- Auction – the buyer pool is built for this. You set a reserve, buyers read the legal pack and bid, and completion is typically 28 days. Our guide to how to sell your house at auction walks through every step.
- Modern Method of Auction – an online sale with a longer reservation period. Read what is Modern Method of Auction to see whether it fits. It can be slower, so check the timetable if you are under pressure.

What should your solicitor check before a BTS sale?
A good Scottish property solicitor will check the following before you list. If you are unsure, our guide to solicitors and auction sales explains what to expect.
- Whether the council has served any notice, closing order or demolition order, and whether it is registered against the property.
- Whether there are charges for work done by the council that have not been paid.
- Whether any shared repairs or factor debts are outstanding. See factor arrears at auction.
- Whether the title is clean and the building warrants and completion certificates are in order.
- Whether the insurance position is clear; empty or defective homes can be hard to insure. See auction insurance.
How much is a BTS house worth?
There is no standard discount, and I would be wary of anyone who quotes one. Value depends on the cost of curing the failings, the location, the plot and what an investor can do with the finished property. The cleanest way to find out is to put it in front of real buyers. A free valuation from our team will give you a realistic guide price and reserve, and our article on guide price vs reserve price explains how those work.
Step-by-step: selling a BTS home in 28 days
- Get the facts. Ask the council whether the property is on its BTS records, and whether any notices have been served.
- Instruct a solicitor experienced in Scottish residential sales.
- Order the Home Report (unless exempt) and keep it honest.
- Get a valuation and agree a reserve you can live with.
- Prepare the legal pack – title, notices, Home Report, searches.
- Market to the right buyers – investors, developers and cash buyers.
- Auction or accept an offer, with a 10% deposit and binding contract.
- Complete within the agreed period, typically 28 days.

Common mistakes to avoid
- Ignoring council letters. They do not go away and can create costs that follow the property.
- Starting repairs without quotes. Costs balloon and the sale price rarely recovers them.
- Leaving the house empty and unheated. Winter makes damp and burst-pipe damage far worse.
- Listing with a mortgage-dependent marketing plan. The buyers will not get a loan.
- Hiding known defects. It delays completion and risks a dispute.
Is buying a BTS house a good idea?
For the right buyer, it can be. Investors and developers regularly buy below-standard houses, repair them and either sell or let them. Buyers should have a surveyor and builder look at the property before bidding, have the finance in place and read the legal pack closely. Our guide to bidding at auction in Scotland covers the practical side.
Our view
A BTS label sounds frightening, but it is a description of condition, not a ban on selling. Be open about the problems, take proper legal advice, and choose a sales route that matches the buyers who actually want this kind of property.
