How to plan a home renovation in 2026: Key steps and advice

Planning a renovation properly is not known as the 'fun bit'.

BUT it is the bit that makes everything else less painful!

Before you start choosing tiles, worktops, paint colours or taps, you need to understand what you are trying to change, what it will affect, who needs to be involved and what needs deciding before work starts.

Most renovation stress comes from things being decided too late.

Before you get into quotes, products or Pinterest boards, work out what the renovation needs to do.

• What is not working now?
• Who uses the space?
• What needs to change day to day?
• Are you renovating for yourself or to add value?
• Is this a cosmetic update or a bigger layout change?

There is a big difference between refreshing a room and changing how a home works.

A bathroom refit, a kitchen extension, a loft conversion and a whole-house renovation all need different levels of planning.

The earlier you are honest about the scope, the easier everything else becomes.

Make a plan before you ask for quotes

You do not need every tiny decision made before speaking to trades.

But you do need enough detail that everyone is quoting the same thing.

A vague brief like "new bathroom" or "open up the kitchen" leaves too much room for interpretation.

• A detailed layout
• What is staying and what is moving
• Any structural changes
• Key fixtures, fittings or appliances
• Electrical requirements
• Heating changes
• Any known constraints
• Photos and measurements

The aim is not to become an architect overnight.

It is to give trades enough information to price the same job, not three different versions of what they think you might mean.

A clear plan also helps later if you move into a formal contract. Drawings, specifications and schedules of work are often the documents that define exactly what is being priced and built.

A to-scale plan is one of the most useful things you can do early.

It helps you understand:

• What actually fits
• Where doors swing
• Whether furniture blocks movement
• Where sockets, switches and radiators need to go
• What might affect plumbing or electrics
• Whether your layout feels realistic before anything is built

This is where Reno comes in.

You can create a plan room by room, add the items you are thinking about using to the millimetre, test different layouts and start building the brief your trades will need.

It is much easier to move something on a plan than after first fix.

Not every renovation needs planning permission.

Some work can fall under permitted development, depending on the property, location and type of work. But you should not assume.

• Planning permission
• Permitted development rights
• Building regulations
• Party wall requirements
• Listed building consent
• Conservation area restrictions
• Structural engineer input

• Extending
• Removing or changing walls
• Changing the roof
• Adding a loft conversion
• Changing drainage
• Working near a shared wall or boundary
• Creating a new bathroom or utility space

If in doubt, check early with your local authority, architect, structural engineer or building control.

It is much better to find out before work starts.

A renovation budget is not just the cost of the visible things.

• Labour
• Materials
• Fixtures and fittings
• Professional fees
• Surveys
• Structural calculations
• Planning or building control fees
• Skip hire
• Delivery costs
• Temporary accommodation if needed
• Contingency

And yes, contingency really matters.

Older homes especially have a habit of revealing things once walls, floors or ceilings are opened up.

• Rotten joists
• Old pipework
• Electrical upgrades
• Damp issues
• Uneven floors
• Material price changes
• Decisions you genuinely could not make until work started

Try not to spend your contingency before the work has even begun! Check out detailed example projects planned on Reno.

Some decisions feel like finishing details, but they are not.

• Wall mounted taps affect pipework
• Concealed showers affect wall depth
• Wall hung toilets need frames
• Kitchen appliance positions affect electrics and plumbing
• Lighting affects first fix wiring
• Floor finishes affect door clearances and thresholds

This is where people get caught out.

By the time the room is plastered, tiled or decorated, your options are much more limited.

Every renovation is slightly different, but most follow a similar pattern.

Usually, the order looks something like:

• Strip out and demolition
• Structural work
• First fix plumbing and electrics
• Windows, doors or major openings
• Insulation, boarding and plastering
• Flooring preparation
• Tiling or fitted finishes
• Second fix plumbing and electrics
• Decoration
• Snagging

The exact order depends on the project.

A bathroom, kitchen, loft conversion and extension will all have different details, but the principle is the same.

The hidden work comes before the pretty work.

A lot of renovation delays come from things not arriving when they are needed.

Tiles, bathroom fittings, kitchen units, worktops, radiators, lights and flooring can all have lead times.

You also need time to check deliveries.

• Damaged
• Missing parts
• In the wrong size
• In the wrong finish
• Later than promised

If you are supplying items yourself, make sure your trade knows exactly what you are ordering.

Some items need to be on site much earlier than you expect, especially anything needed for first fix.

The people you hire will shape the project.

Before you get too far, it is worth asking whether the work is something you should be doing yourself at all.

Some jobs are realistic DIY. Others need proper trades, certification or building control.

Read more on whether you should hire trades or can do it yourself.

Recommendations from people you trust are usually the best starting point.

When comparing trades, look at:

• Similar past projects
• Reviews and references
• Communication style
• Availability
• Whether the quote is detailed
• Whether VAT is included
• Whether materials and labour are separated
• Whether it is an estimate or fixed price
• Payment terms

A good quote should make clear what is included and what is not.

If one quote is much cheaper than the others, make sure you understand why.

This does not need to feel dramatic.

It is just about making sure everyone understands what has been agreed before work starts.

At a basic level, the agreement should answer:

• What work is being done?
• How much will it cost?
• When is it expected to be finished?

For small jobs, this might be a clear written scope and payment agreement.

For larger projects, it may be a formal building contract using a standard template.

You want written confirmation of:

• Scope of work
• Drawings, specifications or schedule of works
• Payment stages
• Start date
• Expected timeline
• Who is buying what
• What happens if something changes
• How variations will be priced
• How delays will be handled
• How you will communicate

Avoid paying large sums upfront.

A deposit can be normal, especially where materials need to be ordered, but payments should usually be linked to clear stages of progress.

Renovation work spreads.

Dust, tools, boxes, deliveries and people moving in and out all affect more than the room being worked on.

• Clear the work area properly
• Protect floors through access routes
• Move fragile or valuable items
• Work out where materials will be stored
• Think about where trades can park
• Agree access
• Set up temporary cooking or washing arrangements if needed
• Keep children and pets away from work areas

If you are living at home during the work, try to keep at least one area clean and usable.

Agree how you are going to communicate before work starts.

• WhatsApp
• Email
• A shared document
• A weekly check-in
• One main point of contact

Try to keep decisions in writing, especially if they affect cost, timing or scope.

Verbal conversations are useful, but they are easy to forget when there are lots of decisions happening quickly.

• What does this change?
• What does it cost?
• Does it affect the timeline?
• Does it affect anything already ordered?
• Does it affect another trade?

• Where exactly do you want this switch?
• Which way should the door open?
• Where is the towel rail going?
• Is this socket centred to the unit or the wall?
• Do you want the tiles to finish here or there?

This is why planning early helps.

The more decisions you can make before the work starts, the less likely you are to make expensive choices under pressure.

Read more on where do you want the light switches and where should towel rails, hooks and toilet roll holders go.

• A layout change can affect plumbing, electrics, flooring and cost
• Some finishing decisions need to be made before first fix
• Materials need checking as soon as they arrive
• Your builder cannot quote accurately from vague ideas
• Older homes usually need more contingency
• A cheap quote is only useful if it covers the same work
• Every change during the build should be discussed in terms of cost and time
• You need somewhere to live, cook, wash or work while parts of the house are unusable!

A renovation will never be completely stress-free.

But a clear plan makes it much easier to get quotes, make decisions, communicate with trades and avoid the avoidable mistakes.

Start with what the home needs to do.

Create a plan.

Understand the approvals.

Choose trades carefully.

Get the details written down.

Then keep using the plan as the project moves from idea to quote to build.
