If you own a home in Huntingdon or St Ives that was built between the 1960s and the late 1970s, there is a good chance your loft holds the same problem as thousands of others across the district. Spray foam insulation was applied to this exact generation of housing on a huge scale, and it is now the single most common reason that sales, remortgages, and equity release applications in this part of Cambridgeshire come to a sudden stop.
This guide explains why Huntingdon and St Ives share this problem so heavily, what it means if a survey has just flagged it on your property, and what to do next.
Why Huntingdon Grew So Fast, and Why St Ives Tells a Different Story
Huntingdon’s growth in the 1960s was not gradual. The town was one of several across the South East and East of England chosen to take on London’s overspill population, alongside towns like Peterborough and St Neots. Families and entire industries relocated from a crowded capital into newly built estates designed to absorb that growth quickly. The population around Huntingdon and the surrounding district expanded dramatically through this period, and the housebuilding that followed was rapid, consistent, and built to the standards of its time.
St Ives took a different path. The town largely resisted taking on London overspill housing in the 1960s, which is part of why its historic centre has retained more of its original character compared with Huntingdon. That said, St Ives still saw its own wave of estate development through the 1960s and 1970s as Huntingdonshire as a whole expanded, and properties from this era around the town carry the same construction profile as those built under the overspill programme nearby.
What both towns share is a concentration of homes built in a narrow window, using broadly similar timber-framed, pitched-roof construction. That shared building era is exactly why both towns now share the same spray foam story. Our spray foam removal Cambridgeshire team sees this pattern repeat across the whole county.
How the Same Story Played Out in Both Towns
When government-backed energy efficiency schemes arrived in the 2000s and early 2010s, including the Carbon Emissions Reduction Target and the later ECO scheme, estates built during the 1960s and 1970s were a natural target. Contractors could move through entire streets of near-identical properties, applying spray foam to the underside of roof timbers at speed.
Huntingdon’s overspill-era estates, many of which still house the original generation of families or their children, were insulated in large numbers during this period. St Ives properties from the same construction era saw the same treatment, even though the town’s overall growth had been slower and more contained than Huntingdon’s.
The result today is consistent across both towns. A homeowner decides to sell, remortgage, or release equity. A surveyor opens the loft hatch. Spray foam is there, covering the roof timbers completely. The surveyor cannot inspect what is underneath it, and that single fact is enough to stop most mortgage lenders from proceeding. According to RICS, the body that sets the standards UK surveyors follow, this is a structural inspection issue rather than a simple paperwork problem, and you can read their position in full in the official RICS spray foam consumer guide.
What This Means for Your Huntingdon or St Ives Sale
Property values across Huntingdonshire have been rising steadily, with the district averaging around £312,000 in late 2025, a rise of roughly 5.6% year on year. St Ives itself sits a little below the district average at around £238,500, while villages and the commuter belt around both towns regularly push past £400,000.
A spray foam flag puts all of that value at risk. Over 90% of UK mortgage lenders will either decline an application outright or place it on hold pending a specialist report once spray foam is found. For a seller in the middle of a transaction, this usually means the buyer’s finance falls through, the sale stalls, and the property returns to the market carrying a known issue that future buyers and their surveyors will also discover.

Where the Problem Is Concentrated
Huntingdon’s overspill-era estates, including areas built through the 1960s and 1970s housing drive, represent the highest concentration of affected properties in the town. These streets were built quickly and to a consistent specification, which is exactly the profile that made them efficient targets for later insulation contractors.
Godmanchester, immediately south of Huntingdon, shares much of the same housing stock and development timeline. Properties here were caught up in the same wave of energy scheme activity.
St Ives estates built during the 1960s and 1970s, particularly on the edges of the historic town centre, carry the same risk profile despite the town’s slower overall growth. The PE27 postcode area sees regular spray foam discovery during property transactions.
Fenstanton and the villages along the A14 corridor between Huntingdon and St Ives have a mix of older village housing and estates from the same construction era, and survey flags are a regular feature of sales here too.
What Removal Looks Like and What It Costs
Most affected properties in Huntingdon and St Ives are semi-detached or terraced homes with standard pitched roofs, which makes them straightforward to clear in terms of access. Removal typically takes one to two days for a standard property.
Typical costs for the area are as follows.
| Property Type | Typical Cost Range |
|---|---|
| Terraced house | £2,800 to £4,200 |
| Semi-detached house | £3,300 to £5,000 |
| Detached house | £3,800 to £6,500+ |
Closed-cell foam adds approximately £500 to these figures. Once removal is complete, accredited technicians inspect the roof timbers fully, discuss any damage with you before further work is agreed, and produce a report your surveyor and lender can rely on.
Frequently Asked Questions
How do I know if my Huntingdon or St Ives home has spray foam?
Open your loft hatch and look at the underside of the roof timbers. Spray foam appears as a thick layer, usually cream or yellow, applied directly to the wood. If you are unsure, a specialist survey will confirm what is present.
Does removing the foam guarantee my mortgage will be approved?
In the large majority of cases, yes, provided the removal is complete and properly documented. A post-removal report gives surveyors and lenders the confirmation they need to proceed.
Can I just find a cash buyer instead?
You can try, but the pool of cash buyers in Huntingdon and St Ives is small relative to mortgage-backed buyers. Most sellers find it faster overall to remove the foam and open the sale to the full buyer market.
Does this service cover Godmanchester and the surrounding villages?
Yes, Godmanchester, Fenstanton, and the wider A14 corridor between Huntingdon and St Ives are all covered, alongside the rest of Huntingdonshire.
