Question answered
What happens after planning permission is granted, and can building work start?
The direct answer
No. Planning permission is one part of the route to construction.
Planning permission establishes that the proposed development is acceptable in planning terms, subject to the decision notice and its conditions. It does not by itself confirm that every condition has been discharged, that the Building Regulations route is ready, that landlord or neighbour matters are settled, that the design is coordinated, or that the contractor's scope and programme are supportable.
The practical test is not simply whether permission exists. It is whether the first proposed work can lawfully, safely and contractually proceed using current information, with the relevant approvals, responsibilities and site arrangements in place.
Decision ruleDo not use the planning decision date as the construction start signal. Use the first proposed site activity and test every dependency that must support it.
Why this matters
The decision sits across several workstreams.
A project can have a valid permission and still carry a condition that restricts commencement. A submission to discharge a condition is not the same as a decision confirming discharge.
Building control, CDM duties, technical design, Party Wall matters, landlord consent, access, insurance, procurement and the building contract operate through different routes. Progress in one route does not complete the others.
The useful owner-side question is therefore: what exactly are we proposing to do first, and what must be true before that activity begins?
The readiness test
Five checks to put on the record.
Planning decision and conditions
Read the decision notice and condition wording against the proposed first activity. Separate pre-commencement requirements from conditions applying later.
Evidence to identify: Decision notice, condition schedule, discharge submissions and written decisions.Building Regulations route
Confirm the chosen building control route, the information submitted, what remains to be designed and how compliance responsibilities are allocated.
Evidence to identify: Application or notice, drawings, specifications, calculations, comments and approvals where issued.Design and pre-construction information
Test whether the contractor has coordinated information for the work it is expected to price, plan and undertake first.
Evidence to identify: Current drawing register, design responsibility schedule, surveys, specifications and pre-construction information.Property and third-party consents
Check the tenure, Party Wall position, access, scaffold, oversailing and any other consent controlled by a landlord, neighbour or highway authority.
Evidence to identify: Lease advice, notices, awards, licences, written consents and access arrangements.Contractor and commercial commitment
Confirm appointment, scope, exclusions, programme basis, payment terms, insurance and how design change will be handled.
Evidence to identify: Tender return, contract particulars, scope, exclusions, programme, insurance evidence and payment schedule.What to do now
A controlled sequence for the owner.
Define the first work
Ask the contractor to describe the first physical site activity, not merely the intended start date.
Build a dependency list
For that activity, list each approval, design item, consent, appointment, payment and site arrangement that must already be effective.
Name the evidence and owner
Record what proves each dependency and who is responsible for confirming it.
Separate confirmed, assumed and unresolved
Do not let an optimistic programme convert an assumption into a confirmed position.
Agree the controlled start
Only then align the contract, payment, mobilisation and first work package with the supported position.
Warning signs
Pause and ask for clarity if any of these appear.
- The team uses 'planning is approved' as the complete answer to whether work can start.
- A condition discharge application has been submitted but no decision has been checked.
- The contractor's first activities are unclear or keep changing.
- Technical design is described as something that will be resolved after mobilisation without a defined responsibility or sequence.
- Neighbour, landlord or access matters are acknowledged but do not appear in the programme.
From project experience
The practical pattern.
On live projects, the gap is often not a total absence of information. The problem is that separate reassuring statements have not been tested against the same first activity and date.
This is a professional observation, not a statistical claim or a project-specific conclusion.Questions to put on the record
Ask for answers that can be checked.
- What is the first activity proposed on site, and on what date?
- Which planning conditions apply before that activity?
- What is the current building control position for that work?
- Which design information does the contractor still need?
- Which consent, licence or third-party decision could stop access or the work itself?
- Who is giving the owner the consolidated readiness recommendation?
Frequently asked questions
What owners usually ask next.
Can enabling work start before every design detail is finished?
Sometimes, but only where the enabling scope is defined and its own approvals, design information, safety arrangements and contractual basis are supportable. Calling work 'enabling' does not remove those requirements.
Does Building Control approval mean the project is ready to start?
Not by itself. It addresses a different control route and does not settle planning conditions, private property rights, contractor scope, procurement or all project information.
Who should confirm readiness?
Each appointed professional should confirm the matters within their appointment. The owner should identify who is responsible for bringing those separate positions together before the commitment is made.
