Selling a BTS Home in Scotland | Scotland Property Auction
Yes, you can sell a house that is below the tolerable standard in Scotland, and auction is often the most realistic way to do it. A home that fails the legal minimum is usually unmortgageable, which rules out most buyers on a normal sale, but cash buyers, investors and renovators bid on these properties every week. This guide explains exactly what "below tolerable standard" (BTS) means, how it shows up in your Home Report, and how to sell with confidence.
- "Below tolerable standard" is a legal test set out in section 86 of the Housing (Scotland) Act 1987, not a surveyor's opinion.
- It is not illegal to sell a BTS home, but you must be open about the defects and most lenders will not lend on it.
- Cash buyers, investors and renovators are your market, and a traditional auction suits them well.
- Price honestly: BTS homes sell on condition and potential, not on what a finished house would fetch.
- Get your solicitor involved early, because the Home Report, title and any council correspondence all feed into the legal pack.

What does "below tolerable standard" actually mean in Scotland?
The tolerable standard is the basic legal minimum a Scottish home must meet to be considered fit to live in. It is defined in section 86 of the Housing (Scotland) Act 1987, and it applies to every home regardless of tenure. A house that fails any one criterion is described as "below tolerable standard", often shortened to BTS.
Under section 85 of the same Act, councils have a general duty to make sure that sub-standard houses in their area are closed, demolished or brought up to the standard within a reasonable time. In practice, the great majority of BTS homes are simply repaired by a private owner or a buyer, and the council only steps in when a problem is serious or a complaint is made.
It is worth separating this from other standards you may have heard of. The tolerable standard is the floor. The Repairing Standard applies to private rented homes, and the Scottish Housing Quality Standard applies to social housing. Neither is a test your own home has to pass in order to be sold, but the tolerable standard is the one lenders and surveyors watch most closely.
What are the criteria a house must meet?
The standard has been added to over the years, most recently in 2022 when fire and carbon monoxide detection were included. According to the legislation, a house meets the standard if it satisfies every one of the points below.
| Area | What the law expects |
|---|---|
| Structure | The house is structurally stable |
| Damp | Substantially free from rising or penetrating damp |
| Light, air and heat | Satisfactory natural and artificial lighting, ventilation and heating |
| Thermal insulation | Satisfactory thermal insulation (added 2009) |
| Water | An adequate piped supply of wholesome water inside the house |
| Kitchen sink | A sink with satisfactory hot and cold water |
| Toilet | A water closet or waterless closet for the exclusive use of the occupants |
| Bathing | A fixed bath or shower and wash-hand basin with hot and cold water (added 2003) |
| Drainage | An effective system for foul and surface water drainage |
| Electrics | An electrical installation that is adequate and safe to use (added 2009) |
| Cooking | Satisfactory facilities for cooking food |
| Access | Satisfactory access to all external doors and outbuildings |
| Fire detection | Satisfactory equipment to detect and warn of fire (added 2022) |
| Carbon monoxide | Satisfactory equipment to detect hazardous carbon monoxide (added 2022) |
Notice how many of these are fixable with modest money: a smoke alarm, a carbon monoxide detector, an electrical certificate. Others, such as structural instability or serious damp, are a much bigger undertaking. That difference matters enormously when you decide whether to repair first or sell as it stands.
How does a BTS rating appear in my Home Report?
Your surveyor will flag it in the single survey section of the Home Report, usually where a defect is serious enough to touch one of the criteria above. You will often see the wording that a property "may be below the tolerable standard", along with a Category 3 rating on the relevant element. For a deeper look at how those ratings work, read our guide to Category 3 Home Report items and our overview of Home Reports and auction sales.
The valuation figure in the Home Report may also be set with a note about the condition, and the report may suggest that a lender would be unlikely to lend. This does not stop you marketing the property. It simply tells every buyer, honestly, what they are dealing with.
Can I legally sell a house that is below tolerable standard?
Yes. Nothing in Scottish law prevents the sale of a BTS house. What the law does require is honesty. You must not mislead a buyer, and your solicitor will make sure the Home Report, the Property Questionnaire and any council paperwork are all accurate and disclosed. A sale that hides defects is the one that ends up back in front of a solicitor months later.
The 1987 Act also keeps a power that is worth knowing about: under section 107, a local authority can make a sale of a house conditional on the purchaser bringing it up to the tolerable standard. This is not a common occurrence in a normal private sale, but it shows the system expects BTS homes to change hands and be improved by their new owners.
If the house is let out, other duties apply, so see our pages on regulated tenancies and tenanted property.
Why is a BTS home so hard to sell on the open market?
The answer is nearly always the mortgage. Lenders value the property as security for their loan, and a home that fails the legal minimum is risky security. Most high-street lenders will refuse to lend, which cuts out the first-time buyers and families who make up most of an estate agent's buyer pool. Our guide to unmortgageable homes at auction explains this in detail.
On a conventional sale, that means long marketing periods, offers that fall through when the lender's valuer visits, and a steady drip of price reductions. Sellers sometimes tell me they spent a year chasing buyers who could never get finance. Here is how the two routes tend to compare.
| Factor | Estate agent sale | Traditional auction |
|---|---|---|
| Typical buyer | Mortgage-reliant occupier | Cash buyer, investor, renovator |
| Lender approval needed | Yes, usually fails on a BTS home | No, buyer must be ready to complete |
| Risk of fall-through | High | Low once the hammer falls |
| Timescale | Open-ended | Around 28 days to complete |
| Price pressure | Repeated reductions | Competitive bidding against a reserve |
For a wider comparison, have a look at auction versus estate agent.
Is auction the best way to sell a BTS home?
For most owners, it is the strongest option, because auction buyers expect problems. They have the cash or bridging finance ready, they can read the legal pack, and they are budgeting for the work. Once the hammer falls on a traditional auction, the sale is binding, and our guide to whether auction is binding in Scotland explains why that gives you real certainty.
- Buyers are cash-ready, so lender refusal is not a problem
- A fixed completion date, usually around 28 days
- Competitive bidding can lift the price above the guide
- Defects are disclosed up front, reducing the chance of renegotiation
- The buyer pool is smaller than for a move-in-ready home
- Pricing too high with the reserve can leave the lot unsold
- You must still pay for a Home Report and legal preparation
- The price will reflect repair costs, not a finished-house value

Should I repair the defects first or sell as it stands?
This is the question I get asked most, and the honest answer is "it depends on which defect it is". A useful rule of thumb is to separate cheap, quick fixes from large structural jobs.
The bars above show how worthwhile it usually is to repair before selling; they are a guide from experience rather than a measured statistic. Cheap compliance items such as detectors cost little and remove a headline defect. Big structural jobs, by contrast, rarely repay the outlay and the delay, because an auction buyer will happily price the work in themselves. See our pages on dry rot, subsidence and renovation homes for those specific problems.
What about quotes and surveys?
If you do decide to sell as it stands, a couple of contractor quotes can help buyers price the work and often reduce the discount they apply for the unknown. Buyers bid more confidently when the cost of the problem is clear.
How should I price a BTS property for auction?
Price on condition. Look at what comparable renovation properties in your street have achieved, then deduct a realistic cost of bringing the house up to standard, plus a margin for the buyer's time and risk. A sensible guide price attracts bidders, and bidders create the competition that can push the final figure higher. Our guides to guide price versus reserve price and below-market-value lots explain the thinking.
| Step | What to do |
|---|---|
| 1 | Find recent sold prices for similar renovated homes nearby |
| 2 | Estimate repair costs using contractor quotes or the surveyor's notes |
| 3 | Deduct repairs plus a buffer for risk and the buyer's profit |
| 4 | Set a guide price that invites bidding and a reserve you are comfortable with |
What does a buyer need to know before bidding?
Buyers need the same honesty you do. They should read the Home Report and legal pack, instruct their own solicitor, and be ready with their deposit and funds. If you are interested from the buyer's side, read bidding at auction in Scotland and auction finance in Scotland. Investors often use bridging loans or specialist refurbishment finance for BTS lots, which is a different product from a standard mortgage.
What should I do now if my home might be below tolerable standard?
Take these steps in order. First, order the Home Report and read the single survey carefully. Second, speak to a solicitor about title and any council correspondence. Third, decide whether any cheap compliance fixes are worth doing. Fourth, get a free opinion on whether auction suits your home. You can request one at any time through our free valuation page, and our Scottish property terms glossary decodes any jargon you meet along the way. Our sell your property page explains the whole service.
