Can I Sell a House in Scotland That Is Classed as Non‑Standard Construction?

If a surveyor, estate agent or buyer’s lender has told you that your home is “non-standard construction”, it can feel as though you have been handed a problem you did not know you had. Thousands of Scottish homes were built after the Second World War using concrete, steel or timber systems rather than traditional brick and block, and many of those homes are now owned privately after being bought from the council.

The short answer is yes, you can sell a non-standard construction house in Scotland. No law stops you, and many of these homes change hands every year. What changes is the pool of buyers, because some lenders will not lend on certain construction types and others want extra reports first. This guide explains the common Scottish house types, how lenders and the Home Report treat them, what engineer reports and PRC repair certificates are, and your realistic options for selling.

What does non-standard construction mean in Scotland?

“Non-standard” (sometimes called non-traditional) is a lending and surveying term rather than a legal one. It describes a home whose main walls or frame are built in a way that differs from conventional masonry: usually brick, block or stone walls with a pitched roof of slate or tiles.

In Scotland the label most often applies to homes built between the 1920s and the 1970s, when councils needed to build quickly with scarce bricks and skilled labour. Builders used precast concrete panels, concrete cast on site, steel frames and imported timber kits. Many of these homes were later bought by tenants under the Right to Buy.

Non-standard does not automatically mean unsafe or poor quality. Some systems have aged well; others have known weaknesses that need inspection or repair. The point is that a lender cannot assume the property will behave like a conventional house, so it asks more questions before agreeing to lend.

Which non-standard house types are common in Scotland?

There were dozens of post-war building systems, but a handful account for most of the non-standard homes in Scotland. Lender attitudes vary and change over time, so treat the final column as a general guide.

House type	How it was built	How buyers and lenders tend to view it
Wimpey no-fines	Walls of concrete made without sand, cast in one piece on site and rendered. Many estates were built in the late 1940s and 1950s, including in Glasgow, Inverness and Renfrewshire.	Widely regarded as structurally sound. Many mainstream lenders will consider them.
Weir houses	Built after the war by the Weir Housing Corporation, part of the Glasgow engineers G. and J. Weir, first in steel and later in no-fines concrete.	Depends on the variant and condition, so a surveyor will want to identify the exact system.
Orlit and other PRC houses	Precast reinforced concrete (PRC) panels or columns. Over time the concrete can carbonate and the steel inside can corrode.	The hardest group to mortgage. Many lenders want evidence of an approved repair.
Cruden	A Scottish design with a light steel frame clad in concrete blocks, usually rendered, built in the late 1940s.	Lenders want to know the condition of the steel frame, as corrosion has been found in some houses.
BISF	Steel-framed houses designed by the British Iron and Steel Federation, with steel sheeting on the upper floor. Examples include Port Glasgow and Dumbarton.	Never designated as defective. Several lenders will consider them, often with a structural report.
Swedish timber houses	Timber kit houses imported from Sweden, many built in Scotland in the 1940s.	Condition is key, especially the timber and cladding.
Modern timber frame	Factory-made timber frame with an outer leaf of brick, block or render.	Normally treated as standard construction by mainstream lenders.

Modern timber frame shows why the label can confuse people. Structural Timber Association figures suggest around three quarters of new Scottish homes use it, so it is usually treated as standard. It is the older, more unusual systems that cause most of the questions.

Was my house on the old “defective” list?

Under the Housing (Scotland) Act 1987, twelve types of PRC house were formally designated as defective. A grant scheme to help owners with repairs ran from 1984 to 1994. The twelve types were Ayrshire County Council (Lindsay), Blackburn Orlit, Boot, Dorran, Myton-Clyde, Orlit, Tarran, Tarran-Clyde, Tee Beam, Unitroy, Whitson-Fairhurst and Winget.

The Scottish Government recognised that the label had stopped helping owners and was instead making it harder to get a mortgage or sell. From 30 July 2018 the designation was repealed by the Housing (Scotland) Act 2014, and the Government published guidance on recognising repair work to these homes. The repeal does not force any lender to change its policy, though. Lending remains a commercial decision, so a PRC house of one of these types can still be hard to mortgage, particularly if it has not been repaired.

How can you tell if your house is non-standard construction?

Many owners only find out when a buyer’s lender declines the application or a surveyor flags it. You can usually get a good idea earlier by checking a few things:

• Your Home Report: the Single Survey describes the construction of the walls, roof and floors, and will normally state if the surveyor considers the property non-traditional.
• Previous surveys and mortgage offers: your own lender may have recorded the construction type when you bought or remortgaged.
• Council or housing association records: if the house was bought under the Right to Buy, the original landlord may know the building system used on the estate.
• The rest of the street: non-standard homes were built as whole estates, so if neighbours have been told their house is a particular system, yours is likely to be the same.
• Visible clues: concrete panels or columns, steel sheeting on the upper floor, unusual render or a pebbledash finish on every house in a uniform layout can all be signs, but only a surveyor or engineer can confirm the type.

Why do mortgage lenders treat non-standard homes differently?

A lender needs to be confident that the house will still be good security for the loan in 25 or 30 years, and that it could be sold easily if the borrower stopped paying. With unusual construction there is less data on how the building will age, some systems have known defects, and fewer future buyers may be able to get a mortgage.

In practice, this means a buyer may find that one lender declines the property outright while another will lend on it with conditions. For you as the seller, the main risk is time: a sale can be agreed and then stall, or fall through, while a buyer’s lender considers the construction. Our guide to what happens when a buyer’s mortgage is declined in Scotland explains where that leaves you.

What lenders commonly ask for

• A structural engineer report confirming that the structure is sound and suitable for lending.
• Evidence of repairs, such as a PRC repair certificate or details of works to a steel frame.
• A larger deposit or a lower loan to value than for a standard house.
• Confirmation of resaleability, for example evidence that similar homes on the estate have sold with mortgages.
• Suitable buildings insurance, which may need to come from an insurer that covers non-standard homes.

What is a structural engineer report and when is one needed?

A structural engineer report is a specialist inspection of the main structure of the house, usually carried out by a chartered structural or civil engineer. For a non-standard home, the engineer looks at the elements that matter for that system, for example the condition of concrete columns in a PRC house, the steel stanchions in a steel-framed house, or the timber in an older timber house.

The report states whether the structure is sound and whether repairs are needed. Lenders often make it a condition of the mortgage offer. The buyer usually arranges it, but some sellers commission one in advance so that buyers and lenders have the information from day one. Ask your solicitor or surveyor whether that would help in your case.

What does a PRC repair certificate mean for a sale?

Many PRC houses have been repaired, often by replacing the concrete panels or columns of the ground floor or the whole outer wall with conventional masonry. Where the work was carried out under an approved scheme, the owner should have a certificate confirming it.

Many repairs were carried out under the PRC Homes scheme run by PRC Homes Ltd, a subsidiary of the NHBC. Since July 2016 BRE Global has operated a PRC Homes Repair Scheme, with registers of approved repair specifications, certified practitioners and repaired properties that lenders can check. A certificate from a recognised scheme is often what makes a PRC house acceptable to at least some lenders.

• Find your certificate: check your title deeds, the papers from when you bought, or ask your solicitor or the council if the work was done before a Right to Buy purchase.
• Check what was repaired: some repairs cover the whole structure, others only part of it, and lenders look closely at the difference.
• Ask about older repairs: BRE Global cannot deal with certificates issued before its scheme started in July 2016; for earlier PRC Homes Ltd repairs, the NHBC may be able to help.

An unrepaired PRC house can still be sold, but most buyers will need cash or a very flexible lender. Get proper quotes and advice before committing to repairs purely to sell.

How does non-standard construction affect your Home Report?

Before you can market a house in Scotland you normally need a Home Report, made up of the Single Survey and valuation, a property questionnaire and an energy report. Our guide to what a Home Report includes and when you need one covers the basics.

For a non-standard home, the Single Survey will describe the construction and may say that the surveyor considers it non-traditional. The surveyor may recommend a structural engineer report, and the valuation will reflect how the local market and lenders treat that type of house. A buyer’s lender will also rely on its own valuation instructions, and the valuer may add conditions such as an engineer report or a repair certificate.

If the survey highlights serious concerns, such as category 3 repairs to the structure, buyers will see that straight away. Our article on what happens if your Home Report highlights major problems explains how to respond. If the report raises structural movement or damp, see our guides to selling a house with damp or structural issues and selling a house with subsidence.

Do you have to tell buyers your house is non-standard?

The construction type will normally be stated in the Home Report, so buyers will find out early in any case. Never try to hide it or describe the house as something it is not, as a buyer who relies on a false statement could bring a claim later.

Be open, share any engineer reports or repair certificates, and let your solicitor answer questions accurately. Our guide to what you have to disclose when selling in Scotland explains more. If the house has been altered, check that paperwork too: see structural alterations not shown on the title plan and extensions without a building warrant.

What are your options for selling a non-standard house?

The best route depends on the construction type, its condition, any repairs and how quickly you need to move.

Option	Works best when	Things to weigh up
Open market, as it is	The type is widely accepted by lenders, such as many no-fines or BISF homes in good condition.	Buyers may still hit lender conditions, so allow extra time for reports.
Open market, with reports ready	You can provide an engineer report, repair certificate or evidence of past works upfront.	There is a cost to commissioning reports, and a lender may still want its own.
Repair first, then sell	An approved repair would make the house widely mortgageable and the uplift justifies the cost.	Repairs can be costly and take months, and need the right specialists.
Sell to a cash buyer	Previous sales have fallen through, the house needs work, or you need certainty and speed.	Cash offers are usually below full market value, so compare the figures carefully.

Repairing before you sell

For some PRC homes an approved repair makes a real difference, but it is a significant building project and you will not always recover the cost in a higher price. Our guides on whether you need to fix repairs before selling and what can reduce the value of a house in Scotland help you weigh this up.

Selling to a cash buyer

A cash buyer does not need a mortgage, so the lender’s view of your construction type does not apply. At Sell My House Fast in Scotland, we buy homes for cash across Scotland, including houses lenders are cautious about, with no viewings, no chain and a date of entry that suits you. Read about selling to a cash buyer versus an estate agent, why cash buyers usually offer less than market value, how to check a cash buyer has the funds and costs to look out for when selling for cash.

Steps to take before you sell a non-standard house

1. Identify the construction type from your Home Report, old surveys or council records, or ask a surveyor.
2. Gather your paperwork, including repair certificates, engineer reports, guarantees and building warrants for any works.
3. Speak to your solicitor early so they can prepare for the questions a buyer’s solicitor and lender are likely to raise.
4. Consider a structural engineer report if lenders usually query your type of house.
5. Get realistic advice on value from agents who have sold similar homes locally.
6. Compare your routes by the likely net figure and timescale for each.

Timescales for open market sales vary a great deal, and extra lender checks can add weeks. Our guide to how long it takes to sell a house in Scotland gives a sense of the typical stages.

Frequently asked questions

Is non-standard construction the same as defective?

No. Non-standard simply means the house was not built with conventional masonry. In Scotland, twelve PRC types were once formally designated as defective, but that designation was repealed on 30 July 2018. Many non-standard homes, such as BISF and no-fines houses, were never on that list.

Can a buyer get a mortgage on a non-standard house in Scotland?

Often, yes. Many lenders will consider well-known types such as no-fines or BISF houses in good condition, sometimes with an engineer report. Unrepaired PRC houses are much harder to mortgage, and a buyer may need a specialist lender or cash.

Do I need a structural engineer report before I sell?

It is not a legal requirement. A buyer’s lender may ask for one, though, and having a recent report ready can reduce delays. Ask your solicitor or surveyor whether it makes sense for your property.

My PRC house has been repaired. Does that solve the problem?

A repair under a recognised scheme, backed by a certificate, usually makes the house acceptable to more lenders. Keep the certificate with your title deeds and give a copy to your solicitor, as buyers and lenders will want to see it.

Will non-standard construction lower my house price?

It can, because fewer buyers can get a mortgage, but the effect depends on the type, its condition, any repairs and the local market. Your Home Report valuation and local agents are the best guide.
