After planning approval

What does planning approval actually mean?

Receiving your approval is a genuine milestone, and it is right to feel relieved and excited. But it helps to understand exactly what it does — and does not — allow. Planning permission confirms that the local authority is happy, in principle, with what you want to build: its size, its appearance and its impact on the area.

What it rarely means is that you can start building tomorrow. Approvals almost always carry conditions, and many of those must be dealt with before work begins. On top of that, planning permission is only one of the approvals you need — building regulations are separate, and we will come to those shortly.

The single most useful thing you can do right now is read your decision notice carefully, from start to finish. It sets out precisely what has been approved and lists every condition attached. Treat it as the rulebook for your project, and check it before making any commitments.

Common conditions to look for

Conditions are the requirements attached to your approval. They are normal and nothing to worry about, but they do need attention — some must be formally discharged before you can begin. Here are the ones homeowners most often encounter.

Building regulations — the next approval

It surprises many homeowners to learn that planning permission and building regulations are two entirely separate things. Planning is about whether you can build what you propose; building regulations are about how it is built — the structure, insulation, fire safety, drainage and everything that makes a home safe and sound.

You need both. Having planning permission does not mean your project meets building regulations, and work that ignores them can be expensive to put right. This is why both approvals matter and why they run on separate tracks.

Building control — either your local authority or an approved inspector — checks that the work complies, usually through a set of inspections at key stages of the build. To get there, your planning drawings often need developing into more detailed technical drawings that show exactly how things will be constructed.

Finalising your design

With approval in hand, the next job is to turn your design into something a builder can actually price and build from. This is where the detail gets pinned down, and it is well worth doing thoroughly before you approach anyone for a quote.

Technical drawings expand your planning drawings into precise construction information. Structural calculations, prepared by an engineer, confirm how the building stands up — beams, foundations and supports. Alongside these, you will start making product selections and specification decisions: the windows, doors, finishes and fittings that define both the look and the cost of your project.

The more of this you settle now, the more accurate your quotes will be and the fewer surprises you will face once work begins.

Obtaining builder quotations

A builder can only give you an accurate price if they know exactly what they are pricing. That is why a proper information pack — your drawings, specifications and any structural details — matters so much. Hand over vague plans and you will get vague quotes that change once the work is under way.

Provide each builder with the same complete set of information: the technical drawings, the specification of materials and finishes, and a clear description of the work you want done. Three detailed quotations is usually enough to give you a reliable sense of the market without overwhelming you, provided each is based on identical information.

Comparing quotations properly

The lowest number is rarely the whole story. To compare fairly, look beyond the headline price at what each quote actually includes and excludes.

• Scope — exactly what work is covered, so you are comparing like for like.
• Exclusions — what has been left out, which is often where cheaper quotes make up the difference later.
• Materials — the quality and specification assumed, as these vary enormously in price.
• Programme — how long the work will take and when they could start.
• Payment stages — how and when payments fall due, which should be tied to work completed.

Preparing for construction

As the start date approaches, a little groundwork makes the build run far more smoothly. Think about site access — where materials will be delivered and stored, and how vehicles will reach the work. Speak to your neighbours early; a friendly heads-up about noise, deliveries and timescales goes a long way to keeping relations good.

Consider any temporary arrangements you will need, such as alternative parking, a temporary kitchen, or somewhere to live if the work is extensive. Order long lead-time items in good time so they arrive when your builder needs them. And agree a realistic project timeline with your builder so everyone shares the same expectations from day one.

Common mistakes after approval

A little awareness now helps you avoid the slip-ups that catch many homeowners out in the weeks after approval:

• Starting too quickly — beginning work before conditions are discharged or building regulations are in place.
• Ignoring conditions — overlooking the requirements on your decision notice, which can invalidate the permission.
• Choosing purely on price — picking the cheapest quote without checking what it leaves out.
• Incomplete specifications — handing builders vague information, leading to quotes that change later.
• Delaying product decisions — leaving choices so late that lead times hold up the whole build.

What to do now

In the first few weeks after approval, a steady, organised approach beats rushing every time. Start by reading your decision notice in full and listing every condition along with its deadline. Then speak to your designer about developing the technical drawings and arranging building regulations.

From there, finalise your specifications and product choices, prepare a complete information pack, and approach around three builders for detailed quotes. While those come in, begin the practical preparations — talking to neighbours, sorting site access and ordering anything with a long lead time. Work through it in that order and you will move from approval to a confident start without the costly stumbles.
