A question, answered
UK homeowner questions answered
Direct, sourced answers to the questions UK homeowners worry about most: whether spray foam will stop a mortgage or sale, whether you must remove it, what happens if you miss a Boiler Upgrade Scheme deadline, why a home gets a zero valuation, whether you can sue an installer, what happened to the Green Homes Grant, and how heat pumps compare with gas boilers. Every figure is linked to a primary source such as gov.uk, Ofgem, RICS or the Energy Saving Trust.
Will spray foam insulation stop me getting a mortgage or selling my house?
Spray foam in a roof can make a UK home harder to mortgage or sell, but RICS says correctly installed and documented foam should not require removal.
Do I have to remove spray foam insulation?
You do not always have to remove spray foam. RICS says correctly installed, documented foam should not require removal. An independent survey decides.
If I miss the grant timescale, do I lose the 7,500 pounds?
Miss a Boiler Upgrade Scheme deadline and you usually do not lose the grant outright. A voucher lasts 3 months (6 for ground source) and can be re-applied for.
Why did my house get a zero valuation?
A zero or nil mortgage valuation usually means a lender sees the property as unsuitable security, often due to spray foam, non-standard construction or defects.
Can I sue the installer, and what happened to the Green Homes Grant?
Faulty home-improvement work gives UK consumers rights under the Consumer Rights Act. The Green Homes Grant closed to applications on 31 March 2021.
Boiler replacement timeline: what to expect
A straight gas boiler swap is usually a one-day job; a relocation or system change takes longer. A heat pump takes several days plus survey and grant steps.
