Planning and conservation in Hillingdon
Planning and building control in this area are handled by Hillingdon Council (London Borough of Hillingdon). Green Belt is extensive. Airport-related noise and height constraints can affect some designs near flight paths — check with the council. Before you design, check whether your property is in a conservation area, is listed or is covered by an Article 4 direction; these change what you can build without permission. Our guide to permitted development in London explains the national rules, and loft conversion regulations covers roof works.
Suburban plots are often larger than inner London, but Green Belt and airport safeguarding can limit height and footprint.
Typical building costs in Hillingdon
Building costs in Hillingdon typically follow outer London rates of about £2,500 to £3,500 per m² for standard residential work, with high specifications and tricky access at the upper end or above. Budget on top for professional fees (about 15%), consents and contingency (8–15%) and VAT at 20% on extensions and renovations. These are indicative industry ranges for 2026, not a quote; see our London cost guide or request fixed quotes from local builders.

Questions about building in Hillingdon
Can I request quotes from builders in Hillingdon?
Yes. Quote requests are accepted from anywhere in Hillingdon, including Uxbridge, Ruislip, Hayes, Northwood, West Drayton, Yiewsley, Eastcote, across London and the wider UK. With your consent, we pass your enquiry to up to 3 local builders who advertise with us.
Do I need planning permission for an extension in Hillingdon?
It depends on your property. Houses outside conservation areas may be able to use permitted development, while flats, conservation areas and Article 4 directions usually mean an application to Hillingdon Council (London Borough of Hillingdon). A Lawful Development Certificate gives certainty.
Should I check a builder’s insurance?
We ask every builder who advertises with us to provide proof of current public liability insurance before they are listed. Always check each builder’s insurance, references, written quote and trade body membership yourself before work starts.
