Colchester planning: 20,800 homes, last say this autumn

Colchester is writing the plan that will decide where houses get built across the district for the next fifteen years, and it is doing it against a hard national deadline. The council’s own Local Development Scheme, published in June 2026, says the Submission Draft goes out for consultation between August and October 2026 and must reach the Secretary of State by December 2026. That consultation is the last formal chance for residents to comment before an inspector takes over. Here is what is in the plan and what happens if the deadline slips.

The number: 20,800 homes

The government’s standard method for calculating housing need produces a figure of 1,300 new homes a year for Colchester. Over the plan period that comes to 20,800 new homes by 2041. Under the December 2024 National Planning Policy Framework this is a mandatory target, not an aspiration, and the council’s Preferred Options plan says so in terms: Policy ST5 commits the council to “plan, monitor and manage the delivery of at least 20,800 new homes in Colchester City between 2025 and 2041”.

For scale, the council says Colchester has delivered over 21,000 new homes since 2001/02, at an average of 940 a year. The new target asks for 1,300 a year, so it is roughly a 38% step up on a forty-year run rate. The council also notes it delivered 1,098 homes in 2023/24 and that over the previous plan period it beat its cumulative target by almost 500 dwellings, so it starts without a backlog to make up.

Where the 20,800 come from

Only about half of the total needs new allocations. The council’s housing supply table breaks down like this:

The 6,117 are sites that already hold planning permission. The 2,200 windfall allowance is an assumption rather than a set of sites: the council has averaged 238 homes a year on unallocated land over the past decade, and has budgeted a more cautious 200 a year for the last eleven years of the plan. The 1,700 is Colchester’s half of the 3,400 homes expected at the Tendring Colchester Borders Garden Community before 2041, out of a scheme that will eventually run to about 7,500 homes split equally with Tendring. The Garden Community’s own Development Plan Document was adopted in May 2025.

That leaves 11,089 homes to be found on newly allocated sites, and those are the ones worth arguing about, because they are the sites that are not yet fixed.

The biggest sites

The Preferred Options plan lists 49 housing allocations. Six of them account for more than 60% of the new-site total:

Marks Tey carries the heaviest combined load: 2,500 homes across two sites either side of the A12 and A120, in a village whose road network is already the pinch point for the A120 junction. Langham’s 900 is the largest single allocation to a village in the Dedham Vale end of the district. Elsewhere the plan spreads smaller numbers widely, including 400 at Great Horkesley, 300 each at Copford and West Mersea, 250 at Eight Ash Green and 175 at Wivenhoe.

The city centre gets a distinct set of smaller, denser allocations: 250 homes on land at Colchester Station, 200 at the Gas Works and Hythe Scrap Yard site, 200 at King Edward Quay, 150 east of Hawkins Road, and 100 each at Britannia Car Park, Vineyard Gate and the Magdalen Street opportunity area. Taken together those are a bet on brownfield regeneration along the Hythe and around the station rather than on more edge-of-city estates.

Why December 2026 matters

The council’s Local Development Scheme is unusually blunt about the risk. The Section 1 Local Plan, adopted in February 2021, should have been reviewed by 2026 and the Section 2 plan, adopted in July 2022, by 2027. Because the review is being done as a single plan aligned to the earlier date, the LDS states plainly that “the plan is now out of date”.

Government has confirmed that plans being prepared under the existing system must be submitted for examination no later than 31 December 2026. Miss it, and Colchester has to start again under the new plan-making system. The council’s own assessment is that this “would be likely to result in a significant delay to plan adoption, potentially taking several years” and would leave the district without an up-to-date plan, with decisions falling back on national policy and the presumption in favour of sustainable development. In practice that means developers winning appeals on sites the council did not choose.

There is a further complication in the background. Local Government Reorganisation could merge Colchester with Tendring and Braintree into a single new authority. The LDS notes that if neighbouring councils have adopted plans and Colchester does not, it creates an imbalance across the wider area and complicates future plan-making.

The timetable

The Regulation 19 stage is different in kind from the one that closed in January. At Preferred Options the council was asking what people thought. At Regulation 19 it is publishing the plan it intends to submit, and comments go to the planning inspector rather than to the council, on the narrow question of whether the plan is legally compliant and sound. If you object to a site near you, that is the stage at which the objection reaches someone with the power to change it.

Finding an application near you

Colchester does not use the Idox planning portal that most Essex councils run. Applications are searched through the council’s own planning search, and there is no weekly validated-applications list of the kind neighbouring districts publish. For consultations on the Local Plan itself, the council uses a separate system at colchester.oc2.uk, where the full Preferred Options plan and every representation made on it can be read.

New housing feeds straight through to prices: the district average was £298,257 in May 2026, down 0.5% on the year, and the allocations above are the main lever the council has over supply.

Frequently asked questions

How many new homes does Colchester have to build?

20,800 by 2041, or 1,300 a year, set by the government’s standard method for calculating housing need. Under the December 2024 NPPF this is a mandatory target.

When can I comment on the Colchester Local Plan?

The Submission Draft, or Regulation 19, consultation runs August to October 2026 according to the council’s June 2026 Local Development Scheme. That is the last formal opportunity before the plan goes to the Secretary of State in December 2026.

What is the biggest housing site in the Colchester Local Plan?

Northeast Colchester at 2,000 homes, followed by 1,500 south of the A12 at Marks Tey and 1,000 north of the A120 at Marks Tey. Marks Tey carries the largest combined total of any single settlement at 2,500.

Is Colchester’s current Local Plan out of date?

Yes, on the council’s own account. The Local Development Scheme published in June 2026 states that because the Section 1 plan should have been reviewed by 2026, “the plan is now out of date”.

What happens if Colchester misses the December 2026 deadline?

The council would have to restart under the new plan-making system. Its own assessment is that this would delay adoption by potentially several years and leave the district deciding applications against national policy, including the presumption in favour of sustainable development.

How many homes will the Garden Community deliver?

Around 7,500 in total at the Tendring Colchester Borders Garden Community, split equally with Tendring. Only 3,400 are expected before 2041, of which 1,700 count towards Colchester’s supply.
