Colchester refuses 1 in 6 planning applications. A tougher council than the national norm.
Colchester received 1,824 planning applications in 2025, submitted to the local planning authority. Of the applications decided across 2024 to 2025, 82.1% were approved and 17.9% refused, against a national refusal rate of 12.4%. That is about 1 in 6 applications turned down, where the country as a whole refuses around 1 in 8. The approval rate of 82.1% sits well below the national 87.6%. By the numbers, this is a harder place to win permission than most.
The year in one line
Colchester's refusal rate of 17.9% is well above the national 12.4%, and annexe applications run at twice the national rate. Home extensions make up more than a quarter of all applications submitted to the council.
What Colchester Is Building
Extensions dominate, with annexes running at twice the national rate.
Home extensions were the most common application type submitted to Colchester in 2025, at 25.6% of all applications. The mix then leans toward adapting existing homes: demolition made up 5.7% and garage conversions 3.1%, while annexe applications ran at 2.0 times the national rate. Dormers, by contrast, appear at less than half the national rate. This is the application mix of a town extending and reworking its existing housing stock.

What runs hot
Annexe applications appear at 2.0 times the national rate. Both annexes and garage conversions point to a town making more of the homes it already has rather than starting from scratch.
The council verdict
A harder yes than most places.
The council approved 82.1% of the applications it decided and refused 17.9%, a refusal rate well above the national 12.4%. About 1 in 6 applications was turned down where the national norm is closer to 1 in 8. That tougher stance is consistent across the 2024 to 2025 period analysed.

Colchester vs The National Norm
Where the town leans, by the numbers.
Set Colchester's mix against the national average and a clear pattern shows. Annexes run at twice the national rate, a sign of a town finding space within existing homes. The categories it does less of are just as telling: dormers appear in only 2.7% of applications here, against 6.0% nationally, a gap of more than 2 to 1. The standout figure, though, is the refusal rate.
Colchester refuses 17.9% of the applications it decides, against a national rate of 12.4%, about 1 in 6 turned down where the country refuses around 1 in 8.
Each bar is Colchester's share of applications submitted in 2025; the marker is the national share. Dormers are the town's biggest divergence below the norm.
Meanwhile, the market
Prices rose alongside the building work.
Permission may be harder to win here, but prices have held their climb: the average Colchester home kept appreciating through the latest full year.
Colchester's planning data tells a consistent story. The council refuses applications more often than the national average, and that stance is clear across the full 2024 to 2025 period. The work itself is mostly homeowners extending and adapting what they already have, with annexe applications running at twice the national rate. For anyone buying here with plans to build, the refusal rate is the constraint worth planning around.
