Appointing a building control provider in Essex

In Essex you can use your district council's building control team (Chelmsford, Colchester, Basildon and others) or a private registered building control approver. Both can approve extensions, loft and garage conversions and issue the completion certificate.

Property you'll be working with in Essex

Interwar and post-war semis, 1960s–80s estates and coastal bungalows dominate. Shrinkable clay across much of the county means foundation depth near trees is one of the most common inspection points.

Planning in Essex

Planning and building regulations are separate approvals. Many Essex extensions fall under permitted development but still need building control sign-off; flood-risk areas near the coast and estuaries may add floor-level requirements.

What building control and approved inspectors charge in Essex

Roughly £400 to £900 for a single-storey extension in 2026, £450 to £950 for a loft conversion and £250 to £600 for removing a load-bearing wall. Check your district's published fee schedule.

How to choose a building control provider in Essex

Every extension, conversion, structural opening and rewire needs building control approval, either through your council or a registered building control approver. Arrange it before work starts.

  1. Decide between your local authority and a registered building control approver early.
  2. Confirm how many inspections are included and what triggers an extra charge.
  3. Ask how much notice they need for each inspection stage.
  4. Keep the completion certificate: you will need it when you sell.
  5. Check who notifies the council if you use a private approver.

Common questions

Is building control the same as planning permission?
No. Planning controls what you may build; building control checks that it is built safely and to the regulations. Many projects need both.
What does building control cost in 2026?
Around £700 to £1,500 for a typical domestic extension on a full plans application.
