What does insulation cost in Teesside?

Loft insulation to the full 270mm costs £400 to £800 on a typical Teesside semi in 2026, cavity wall fill runs £700 to £1,500 with a 25-year CIGA guarantee, spray foam removal £2,000 to £4,000 including the lender's timber report, and internal wall insulation for solid-wall terraces £4,000 to £8,000. Eligible homes get much of it free under ECO4.

The range is honest: house size, access and what the survey finds move the number. What should never vary is clarity: every quote here is itemised line by line after a proper survey, not guessed from a postcode.

Full breakdowns are in our Teesside insulation cost guide.

Teesside houses, Teesside heat loss

Insulation here has local texture. The Victorian terraces of Middlesbrough and Saltburn have solid walls, suspended floors and lofts last touched in 1978. The 1930s semis of Acklam and Fairfield have empty cavities and thin loft wool. Ingleby Barwick's new-builds meet the minimum standard and no more. And a generation of 2010s lofts got spray foam that now blocks mortgages. Each of those is a different job with a different price, and every quote comes from an installer who knows which one your house is before writing a number.

Every survey checks what actually matters: cavity condition and exposure before filling, ventilation before insulating, timber condition before certifying.

What a proper quote includes

• A real survey: boroscope checks on cavities, moisture readings, ventilation and access assessed before pricing.
• Itemised pricing: materials, labour, making good and waste each on their own line.
• Honest advice: roughly one surveyed cavity wall in five gets told no. You hear it free, before any drilling.
• Guarantees in writing: 25-year CIGA on cavity fills, documented timber reports on foam removal.
• Grant check as standard: ECO4 and LA Flex eligibility confirmed at the survey, funded route quoted alongside the private price.

Where to start

Most insulation questions start with three: what should it cost, is my cavity fillable, and what about this spray foam? Our cost guide answers the first with real 2026 figures, the spray foam mortgage guide walks through the sale-blocking foam problem, and the ECO4 guide explains who gets it free. The quote form handles the rest.
