Every property developer knows the excitement of spotting a high-potential site but without planning permission, even the best opportunity can become a costly mistake.

Whether you’re pursuing your first planning uplift or scaling multi-site developments, the truth is: planning is the gatekeeper to profit, progress and peace of mind. And yet, it’s one of the most misunderstood stages in a project.

Planning Is a Developer’s Gatekeeper

Planning permission can unlock serious value, but it can also tie up cash, delay timelines, and derail your exit plan.

Whether you’re:

• Flipping with a planning uplift,
• Building new residential or commercial units,
• Converting or extending an existing structure,

It’s essential to understand where planning fits into your development model, and how to mitigate the financial exposure that comes with it.

Outline vs. Full Planning – What’s the Difference?

There are two key types of permission:

• Outline Planning Permission gives you approval in principle for a type of development (e.g. a block of flats), but without full design details. It’s useful for adding value or securing initial lender/investor interest.
• Full Planning Permission includes the specific design, layout and materials. It’s required before construction and refinancing.

Some developers stop at outline to sell the site on. Others need full approval to start or scale. But either way, knowing which to go for, and when, can significantly affect valuation, tax planning and deal structure.

Tax and Cost Implications of Delays or Rejections

Delays in planning can:

• Extend your holding costs (interest, rates, insurance)
• Push back revenue and loan repayments
• Trigger tax issues, like missed SDLT reliefs or ATED charges
• Disrupt your personal income plans (salary/dividends)

A planning rejection might also reduce site value, trigger clawbacks in an option agreement or make lender covenants harder to meet.

At GoldHouse, we work closely with developers to forecast the tax position at every stage, so you can adjust before delays become expensive.

Strategies to De-Risk Pre-Planning Acquisitions

You don’t need to gamble your entire budget on uncertain outcomes. There are smarter ways to structure pre-planning deals:

• Conditional contracts: Only complete the purchase if permission is granted.
• Option agreements: Lock in a purchase price while you pursue planning.
• Joint ventures: Share risk with landowners or equity partners.
• SPV structuring: Isolate risk in its own company for tax and compliance control.

We advise clients on how to structure land deals for maximum flexibility and minimal exposure, especially where planning is a known hurdle.

Permitted Development and Prior Approval: Don’t Get Caught Out

Some developers assume that permitted development rights or prior approval routes are a shortcut, but these still come with strict rules and timelines. For example:

• Converting commercial to residential
• Changing buy-to-lets into HMOs (in non–Article 4 areas)
• Relying on the 56-day prior approval window for planning decisions

These paths can be faster than full planning, but only when structured and documented properly.

We’ve seen too many developers attempt these routes on their own, without the right company setup, exit strategy, or tax plan in place. The result? Tens of thousands (or even millions) lost to avoidable tax bills, delays, or refusals that could’ve been mitigated with early advice.

From longer timelines and extra professional fees to missed finance milestones or resale opportunities, the cost of “just getting on with it” without a proper structure is rarely worth the risk.

Working With Planning Consultants Effectively

Your planning consultant is a critical part of the team. They don’t just fill out forms, they interpret local policy, navigate objections, and position your proposal for approval.

To get the most value from them:

• Engage early – ideally before you exchange.
• Share your end goal (flip, build-to-let, SSAS investment, etc.)
• Align their timeline with your lender or investor expectations.
• Keep communication open between your accountant, solicitor, and planning team.

We often work alongside planning consultants to help forecast cash flow, tax outcomes and investor returns based on a range of possible planning scenarios.

How to Factor Planning into Your Development Model

When building your feasibility model, always include:

• Planning application costs and consultant fees
• Timeline for approval (and worst-case delay buffer)
• Tax consequences of holding the site longer than expected
• Different exit values for outline vs full planning

At GoldHouse, we don’t just support your tax compliance, we help you plan forward, model scenarios, and make strategic decisions grounded in numbers.
