Right to Buy Resale Problems: What Sellers and Buyers Need to Know

The Right to Buy scheme has helped over two million council tenants become homeowners since 1980. But the properties that were purchased — often at substantial discounts — come with conditions and characteristics that can create significant complications when it comes to reselling. If you're looking to sell an ex-Right to Buy property, or buy one on the open market, this guide covers the key issues you're likely to encounter.

What Is the Right to Buy Scheme?

Right to Buy allows eligible council tenants in England to purchase their home at a discount. The maximum discount is currently £102,400 (£136,400 in London), and the scheme has produced a large tranche of owner-occupied properties that were originally built to social housing standards by local councils.

Right to Acquire is a similar scheme for housing association tenants. Many of the same resale complications apply.

Pre-Emption Clauses: The Council's First Refusal

This is the condition that catches many RTB property owners off guard. Under the Housing Act 1985, if the original RTB purchaser sells the property within 10 years of the original purchase, the council has the right of first refusal at the full market value.

How Pre-Emption Works in Practice

1. You decide to sell your RTB property within 10 years of your original purchase
2. Before marketing the property, you must notify the council of your intention to sell
3. The council has a defined period (typically 8 weeks) to decide whether to buy the property at the market value you intend to ask
4. If the council declines or doesn't respond within the deadline, you are free to market on the open market
5. If the council accepts, they purchase at the market rate — this is a normal sale at full price

How to Check Your Pre-Emption Status

Check your original Right to Buy completion paperwork and the title register at HM Land Registry. The pre-emption clause will appear as a restriction or charge on the title. If you're unsure, your conveyancer can check the title for you.

The 10-year period runs from the date of original RTB completion, not from when you subsequently bought the property. If you bought the property on the open market from an RTB purchaser, the pre-emption period runs from their purchase date.

Discount Repayment: The First Five Years

Separate from the pre-emption clause, the RTB discount must be repaid if the property is sold within 5 years of the original purchase. The repayment is on a sliding scale:

Note that the repayment is based on the original discount amount, not the increase in property value. If property values have risen significantly, this may be far less than you expected.

Example

Maria purchased her council flat under Right to Buy in 2023 at a discount of £70,000. In 2025 (year 2), she needs to sell. She must repay 80% × £70,000 = £56,000 to the council. Her net position from the sale still benefits from any price appreciation on top of the discounted purchase price, minus this repayment.

Non-Standard Construction: The Big Mortgage Barrier

Perhaps the most significant challenge for ex-council property buyers is construction type. Local authorities built homes at scale in the post-war decades using methods that are now classified as non-standard construction. These include:

Wimpey No-Fines Concrete

Poured concrete construction developed by George Wimpey, widely used for council housing in the 1940s–1960s. Characterised by a rough concrete texture (no fine aggregate in the mix). Generally structurally sound if maintained, but many mortgage lenders are cautious.

Airey Houses

Prefabricated concrete post and panel construction built primarily between 1946 and 1955. Designated as a defective property type under the Housing Defects Act 1984. Some Airey houses have been repaired and re-rendered, but lender acceptance depends heavily on the specific repair and documentation.

Reema Construction

Hollow precast concrete panel construction, common in the 1960s and 1970s. Another designted defective type. Again, repaired properties may be mortgageable but lender requirements are strict.

Other Non-Standard Types Found in Ex-Council Stock

• Bison large panel system — used in multi-storey blocks
• Laing Easiform — in-situ concrete construction
• Cornish Units — precast concrete used in Cornwall specifically
• Steel-frame — various types including Orlit, Unity, and Boot constructions
• Timber frame — less of an issue than concrete but still requires lender consideration

Impact on Mortgageability

Many mainstream lenders will not lend on non-standard construction properties at all. Those that do will typically:

• Require a full structural survey (Level 3 RICS survey)
• Lend at lower LTV ratios (often 75–85% rather than 90–95%)
• Apply higher interest rates
• Insist on the property being in good structural condition

This limits the buyer pool significantly. Buyers must either purchase with cash or find a mortgage from a specialist lender.

Lender Restrictions on Ex-Council Properties

Even where the construction type is standard (traditional brick and mortar), some lenders apply restrictions to ex-council properties. These typically relate to:

Location in a block or estate: Lenders sometimes have concerns about high concentrations of social housing — for example, if more than a certain percentage of properties in a block or development remain in council/housing association ownership.

Deck-access and walkway properties: Blocks with access via external decks or walkways (the design common in 1960s–1970s tower blocks) are viewed less favourably than conventionally accessed blocks.

Floor height restrictions: Many lenders will not lend on flats above a certain floor level in high-rise blocks — typically the fourth or fifth floor and above.

Minimum size requirements: Some ex-council flats, particularly studio and one-bedroom properties built to space standards of the era, fall below modern minimum size requirements (30 sqm for studios).

High-Rise Ex-Council Flats: Additional Complications

Ex-council high-rise flats face the general challenges of all high-rise properties — magnified by their age and the nature of council-era construction.

EWS1 Certificates and Cladding

Many ex-council tower blocks were retrofitted with external cladding in the 1990s–2000s. Post-Grenfell, the requirement for an External Wall System (EWS1) fire assessment certificate has become standard for mortgage lenders on any building over 11 metres. If an EWS1 has not been obtained — or if it rates the building as B2 or A2 — mortgage lending becomes extremely difficult or impossible.

Check with the building's freeholder or managing agent whether an EWS1 certificate is in place before marketing a high-rise flat.

Service Charges and Major Works

Ex-council blocks often have the council as their landlord/freeholder after RTB — the original tenant bought their flat but the council retained the freehold. This means service charges are set by the council, and you have limited ability to challenge decisions about major works.

Significant major works — roof replacement, lift replacement, fire safety improvements — can result in very large section 20 notices and charges to leaseholders. These can run to tens of thousands of pounds and are a legitimate deterrent for buyers.

Service Charge Disputes with the Council

If you are a leaseholder in an ex-council block and your service charges seem unreasonable, you have recourse. The First-tier Tribunal (Property Chamber) can assess whether service charges are reasonable. This process takes time but can significantly reduce charges.

Be aware that ongoing service charge disputes may affect your ability to sell — buyers and their solicitors will want to see the history of charges and any disputes before exchanging.

Specialist Brokers for Ex-Council Properties

The good news is that ex-council properties — even with non-standard construction — are not necessarily unmortgageable. There are specialist mortgage lenders who understand these properties and are willing to consider them on their individual merits.

Specialist lenders that may consider ex-council or non-standard properties include:

• Precise Mortgages
• Pepper Money
• Kensington Mortgages
• The Mortgage Works
• Foundation Home Loans
• Various building societies with manual underwriting — including some smaller regional societies

The key is working with a whole-of-market broker who specifically understands non-standard construction and ex-council properties. A broker with this experience will know which lenders are likely to consider your specific construction type and can present the case effectively.

For Sellers: How to Prepare Your RTB Property for Sale

1. Check your pre-emption position — confirm whether the 10-year period has elapsed. If not, you must notify the council before marketing
2. Confirm the discount repayment position — if within 5 years of the RTB purchase, calculate the amount you'll need to repay
3. Obtain your construction details — know your property type and have any existing survey documentation ready
4. Get an EWS1 certificate (for flats in applicable buildings) — if one isn't in place, the building's freeholder should be pursuing this; it may be worth chasing them before you go to market
5. Collate service charge records — three years of accounts if possible
6. Instruct an experienced conveyancer — RTB resales have specific legal complications; not all high street solicitors are familiar with them

For Buyers: Due Diligence on Ex-RTB Properties

1. Commission a Level 3 RICS survey — essential for non-standard construction types
2. Check the title for pre-emption clauses — your solicitor will do this, but ask specifically
3. Ask about construction type and confirm with your broker before making an offer — establish mortgageability in principle before spending money on surveys
4. For flats: ask for the EWS1 certificate, service charge accounts, and section 20 notices
5. Consider specialist mortgage advice early — mainstream lender rejection on an ex-council property does not mean you cannot get a mortgage; it means you need a different lender
