Survey finding
Oil heating on your survey: costs and future-proofing
Oil heating has specific maintenance and regulatory considerations. This page covers them.
Last updated: 6 May 2026. Editorially reviewed: 20 May 2026.
Finding
Oil heating property
What this usually means
Oil heating is common in off-gas-grid rural areas. Surveyors flag tank condition (steel tanks rust; bunded plastic tanks last 20 years), oil supply security, and boiler efficiency. From 2025, new oil boiler installations face restrictions in some scenarios.
Why it matters
Replacement budget and future heating regulation are the main considerations.
Ask your surveyor
- Check:What is the tank type and condition?
- Check:Is the boiler nearing end of life?
Ask the seller
- Check:When was the tank last replaced?
- Check:Is the tank bunded?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.
