Getting planning permission for your new garage is a major milestone. After weeks or even months of waiting, you finally have the green light from your local council. But what happens now? What steps should you take before construction begins – and how can you make sure the project runs smoothly from start to finish? Here’s a practical guide to what comes next once your planning permission is approved.

Review your planning permission carefully

Even though permission has been granted, it’s essential to read the decision notice and any accompanying documents in detail. Councils often attach conditions to approvals – for example, restrictions on materials, height, or distance from boundaries. You may also need to submit further details, such as samples of materials or drainage plans, before work can start.

Check whether there’s a time limit for starting the build. In most cases, planning permission expires if work hasn’t begun within three years of the decision date. If anything is unclear, contact your local planning officer for clarification before you proceed.

Finalise your building plans

Once you understand the conditions, it’s time to plan the build itself. Confirm your final design and ensure it complies with both the planning permission and Building Regulations. Even if your garage is small, you may still need Building Control approval to ensure it meets safety and structural standards.

Decide whether you’ll build it yourself or hire professionals. DIY can save money, but it requires skill, time, and the right tools. If you’re using builders, get at least three written quotes, check references, and make sure contracts clearly set out costs, timelines, and responsibilities.

Arrange the right insurance

Before any work begins, make sure you’re properly insured. As the homeowner, you’re responsible for ensuring the site and workers are covered. Key policies to consider include:

• Public liability insurance – covers injury or damage to third parties.
• Contract works insurance – protects materials and the structure during construction.
• Employer’s liability insurance – required if you directly employ anyone to work on the project.

If you’re using a contractor, ask for proof of their insurance before they start. It’s also wise to inform your home insurer about the project, as building work can affect your existing cover.

Prepare the site

A well-prepared site helps the build go smoothly. Clear the area of vegetation, debris, or old structures, and make sure boundaries are correctly marked. If you’re close to a neighbour’s property, double-check the boundary lines to avoid disputes later.

You may need to arrange temporary access for vehicles and deliveries, or protect existing driveways and lawns from damage. If excavation is required, ensure underground services such as gas, water, and electricity are identified before digging begins.

Monitor the construction process

Once work starts, keep a close eye on progress. Whether you’re managing the build yourself or using a contractor, regular checks help ensure the work meets the approved plans and Building Regulations. Take photos as the project progresses – they can be useful if any issues arise later.

If you’ve appointed a builder or project manager, maintain open communication and hold brief site meetings to review progress, costs, and any changes. It’s much easier to address problems early than to fix them after completion.

Notify Building Control and complete inspections

Throughout the build, your local Building Control officer (or an approved inspector) will need to carry out inspections at key stages – for example, after foundations are laid and before the structure is completed. These checks confirm that the work meets safety and quality standards.

When the garage is finished, you’ll need a completion certificate from Building Control. This document proves that the building complies with regulations and is safe to use – and it’s essential if you ever sell your property.

Make the garage ready for everyday use

With the paperwork complete, you can focus on making the garage practical and comfortable. Think about how you’ll use the space: purely for parking, as a workshop, or for storage? Plan lighting, power sockets, and ventilation accordingly. If you intend to use it year-round, consider insulation and heating options.

A well-designed garage can add real value to your home – not just financially, but in terms of convenience and lifestyle.

From permission to completion – a project well managed

Securing planning permission is only the first step. Careful preparation, good communication, and attention to detail will help you avoid delays and unexpected costs. By following the right procedures and keeping everything properly documented, you’ll soon be able to enjoy a new garage that’s both functional and fully compliant with UK regulations.
