A successful home improvement project starts with a clear brief, not a shopping list. Use this checklist to decide what you want to change, understand the constraints of your property and compare proposals on the same basis. This guide is for UK homeowners; planning and building control rules differ across the four nations, so confirm the rules for your address before work begins.
1. Define the outcome before the work
Write down the problem in ordinary language. Is the kitchen difficult to use, is the bathroom short on storage, or does your home need a better connection to the garden? Describe what a finished project must do for you. This separates essential work from attractive extras when choices become difficult.
- List the people who will use the space and the activities it must support.
- Record what works well now and should be retained.
- Rank your priorities as must have, useful and optional.
- Take photographs and measurements before speaking to designers or trades.
2. Check the constraints early
A room can look straightforward until you account for structure, drainage, electrics, ventilation and access. Identify any walls you hope to move, the location of existing services and the route materials will take through the property. If your project affects a leasehold home, a listed building or a shared boundary, raise that at the outset.
Planning permission and building regulations approval are separate questions. Some work can fall within permitted development rights, while other work requires an application. Building regulations can apply even when planning permission is unnecessary. The Planning Portal common projects guide is a useful starting point; check the position with your local planning authority or building control body for your exact proposal.
3. Build a scope that can be priced
A useful brief says what is included, what is excluded and which decisions remain open. For a bathroom, that might mean the exact number of fittings, whether plumbing stays in place, the areas to be tiled and who removes waste. For a kitchen, it might cover units, appliances, electrical points, flooring and making good after installation.
- Prepare a simple room plan with dimensions and the intended layout.
- Specify finishes or give a realistic quality level where you have not chosen a product.
- State who will buy fixtures and materials.
- Ask what preparation, disposal, testing and certification are included.
- Mark provisional items clearly so quotes can be compared fairly.
4. Plan the budget as a range
A single headline price hides important differences. Separate the likely spend into design and approvals, labour, materials, fixtures, delivery, waste removal and a contingency. Your contingency is not an invitation to spend more; it is room for issues that only become visible once work starts. Avoid publishing a budget as a promise of what a project will cost, because property condition and specification can change the result substantially.
When comparing quotes, check whether VAT is included, whether allowances are realistic, the payment schedule and how variations will be agreed. A cheaper quote that omits preparation or finishing may cost more once the missing work is added. Use the free project budget planner to organise these line items and add a contingency.
5. Choose the right people and sequence
Decide whether the job needs one main contractor, several separate trades or design input before you seek prices. Ask each candidate to price the same brief and explain their assumptions. Check relevant qualifications and insurance, and ask who is responsible for building control notifications or certificates where they apply.
Then sketch the sequence: survey, design, approvals, ordering, preparation, first fix, inspection, finishes and handover. Long lead items can delay work even when the site is ready, so confirm delivery dates before agreeing a start date. Put decisions with deadlines in writing.
6. Agree the paperwork before work starts
Keep one record of the agreed scope, drawings, specification, price basis, payment schedule, expected timetable and process for changes. Make sure you know who supplies products, who protects the rest of the home and who clears the site. Ask how unexpected work will be priced and approved before it proceeds.
Keep copies of approvals, test certificates, warranties, manuals and final invoices together. Government guidance explains that missing building regulations documentation can create problems when you later sell a property. See GOV.UK building regulations approval for the current position in England.
7. Check the result against the brief
At handover, walk through the original scope rather than judging the room only by appearance. Test fittings, lights and ventilation; note unfinished items; and agree when they will be corrected. Ask for the documents and product information promised in the quote. A short written snagging list makes the final conversation much clearer.
A one page project brief
Copy these prompts into a document before you request quotes: What problem are we solving? What must the finished space do? What work is included and excluded? Which dimensions and existing services matter? Which approvals may apply? Who supplies materials? Which decisions are still open? What is the target timetable and budget range? The answers will make every subsequent conversation more useful.
