Last reviewed March 2026 — LetterSure editorial team
A neighbour has submitted a planning application you are concerned about. Here is how to write a formal objection that councils are required to consider — and what makes an effective objection versus one that gets ignored.
Yes — anyone can submit a formal objection to a planning application in the UK. Planning applications are public documents and councils must consider all representations received during the consultation period before making a decision. Your objection will be read by the planning officer handling the application.
However your objection must be based on material planning considerations — not personal preference or the impact on your property value. A well-argued objection based on valid planning grounds carries significantly more weight than a general letter of complaint.

The development would allow overlooking into your home or garden that did not previously exist.
Overshadowing and loss of light
The development would significantly reduce natural light to your home or garden.
Overdevelopment of the site
The proposed development is too large or intensive for the plot it sits on.
Harm to the character of the area
The development is out of keeping with the scale, style, or character of the surrounding area.
Increased traffic and parking
The development would generate additional traffic or parking pressure that the local road network cannot accommodate.
Noise and disturbance
The use proposed would generate noise or disturbance that would harm neighbouring amenity.
Flood risk
The development would increase flood risk to neighbouring properties or the surrounding area.
Planning officers cannot take into account personal disputes with the applicant, concerns about property values, the applicant's character or history, or general dislike of the proposed design. Including these in your objection will not strengthen your case and may undermine the credibility of your valid planning grounds. Stick strictly to material planning considerations.
Find the application on your council's planning portal using the application reference number — this will be on the site notice or neighbour notification letter you received. Submit your objection online, by email, or by post before the consultation deadline — usually 21 days from the date the application was publicised.
Keep a copy of your objection and any confirmation you receive. If you submit online you will usually receive an automatic acknowledgement. Multiple objections from different residents carry more weight than a single objection — talk to your neighbours about submitting their own representations.

Can I object to a planning application?
Yes. Anyone can submit a formal objection. Councils must consider all representations received before making a decision. Your objection must be based on material planning considerations — not personal preference or property values.
What are valid grounds for a planning objection?
Valid grounds include overlooking and loss of privacy, overshadowing, overdevelopment, harm to the character of the area, increased traffic and parking, noise and disturbance, and flood risk.
How do I submit a planning objection?
Find the application on your council's planning portal and submit your objection online, by email, or by post before the consultation deadline — usually 21 days from when the application was publicised.
Does a planning objection stop development?
Not automatically. Councils must consider objections but are not required to refuse based on them alone. A well-argued objection based on material planning considerations carries more weight than a general objection.
How long do I have to object?
The standard consultation period is 21 days from when the application was publicised. Check your council's planning portal for the specific deadline. Late objections may not be considered.
