Property Development in England: Planning Opportunities and Market Risks

Property development is rarely about deciding whether the market is “good” or “bad”. There is simply the market we are operating in. Our job is to understand it, test the figures and decide whether an individual opportunity stacks up.

October 2026 brings a mixture of planning opportunity and commercial risk. The planning system continues to face pressure to deliver more homes, while buyers remain price-sensitive and construction costs require careful control. That combination can reward developers who buy well and make decisions based on evidence rather than optimism.

Planning policy can create opportunity—but it does not remove site-specific risk

Recent planning decisions continue to show the weight that can be given to housing delivery, the development plan and national policy. That may strengthen the prospects of some residential proposals, particularly where an authority cannot demonstrate a strong housing position or where a scheme makes effective use of suitable land.

However, a national policy direction is not permission to assume that any site will succeed. Access, highways, drainage, ecology, biodiversity net gain, design, heritage, neighbouring amenity and affordable-housing requirements can still determine whether a project is viable.

Before buying, we need to understand both the planning opportunity and the cost of securing it. A promising planning argument has limited value if the resulting obligations, abnormal costs or reduced unit numbers destroy the appraisal.

Do not confuse planning optimism with a safe land purchase

A site without permission may offer the greatest uplift, but it also carries the greatest uncertainty. Full planning permission can reduce risk, although only if we intend to build substantially what has been approved. Outline permission and positive pre-application advice are useful, but neither guarantees that the final scheme will be acceptable or commercially deliverable.

Conditional contracts, options and purchases subject to planning can sometimes align the land price with the eventual consent. The right structure depends on the owner, the site and the amount of work needed before a reliable value can be established.

Stress-test the exit value

Sales evidence should be current, genuinely comparable and adjusted for differences in specification, size, position and timing. If the appraisal only works at the highest possible resale value, the margin may be too fragile.

I would normally want to see what happens if sales values are lower than expected, sales take longer or incentives are needed. Finance, council tax, utilities, insurance, security and marketing costs continue while completed property remains unsold.

Well-priced homes can still sell in a cautious market. Overpriced homes may sit, and a developer cannot assume that the market will rescue an ambitious appraisal by completion.

Get construction prices onto the same basis

Contractor quotations are difficult to compare when the scope, specification and exclusions differ. A lower price may omit scaffolding, temporary services, drainage connections, external works, professional fees, warranties, testing or final certification.

Whether we use a main contractor, manage individual trades or adopt a hybrid approach, each price should be measured against the same information. We also need a realistic contingency and a clear process for approving variations before additional costs are incurred.

The aim is not simply to choose the cheapest quotation. It is to understand the likely total cost of completing the scheme to the required standard.

Housing standards increasingly affect the long-term risk

Government attention on damp, mould and the condition of rented homes is another reminder that design and construction decisions do not end at practical completion. Ventilation, insulation, heating, drainage and moisture management affect occupiers, maintenance costs and future liability.

Developers should consider buildability and compliance early, keep proper records during construction and make sure the completed property can be operated and maintained as intended. Regulations and professional requirements should always be confirmed for the specific project with the appropriate advisers.

What should a developer do now?

First, concentrate on the individual opportunity. Establish the realistic planning position, produce a properly detailed appraisal and challenge the sales evidence. Obtain comparable construction prices, identify abnormal costs and allow enough contingency for the stage the project has reached.

Second, decide which risks can be reduced before committing. That might mean further surveys, planning advice, a conditional purchase, revised design work or more detailed contractor pricing.

Finally, be prepared to walk away. A difficult market can create good buying opportunities, but only when the purchase price reflects the risks and the scheme still produces a sensible return.

Experience helps before the commitment is made

The most expensive property-development mistakes often begin before a site is purchased: overestimating the planning potential, relying on an optimistic exit value or failing to identify costs that should have changed the offer.

My one-to-one mentoring is built around the actual development you are considering. We can examine the site, planning position, appraisal, professional team and construction strategy together. I will not make the decision for you, but I can help you ask the right questions before you commit.
