Most renovation overruns and bills for rework come from doing the right jobs in the wrong order, or from making decisions too late. This guide sets out the sequence, the checks between stages, the decisions you need to have made in advance and a checklist you can use with any builder. It is about order, not duration: for how long each phase takes, see our full house renovation timeline.
Why the Order Matters
Renovation work is a chain. Each trade builds on the one before and hides what it did. Cables and pipes disappear behind plaster, plaster hides the wall, paint and flooring hide the plaster. If something is wrong and it has already been covered, you pay twice: once to open it up and once to make it good.
A simple example is plastering. If the plasterer finishes the walls before the electrician has finished, the new plaster is cut back to chase in cables, then patched, and the patches often show through paint. The same job done in order costs nothing extra. Getting the sequence right is free; getting it wrong is not.
The Order at a Glance
Not every project has every stage, and some overlap on a good site. But for a full renovation this is the order that avoids rework, with the check that should happen before moving on.
| Stage | What happens | Check before the next stage |
|---|---|---|
| 1. Survey, plans and permissions | Inspect the house, agree scope and budget, get drawings, planning and building control sorted, book the builder. | Written quote and contract, permissions in place, key design choices made. |
| 2. Strip-out | Old kitchens, bathrooms, flooring and plaster removed, skips ordered, services isolated. | What was hidden is now visible. Photograph it and flag surprises (damp, rot, old wiring). |
| 3. Structure and weatherproofing | Wall removal, steels, extension groundworks, roof and windows, so the building is dry and secure. | Structural sign-off where needed, and the house is weathertight before internal work starts. |
| 4. First fix | Electrical cabling, plumbing, heating pipework and ducting go in behind where the walls will be. | Electrician and plumber confirm they are finished. Pressure tests done where relevant. |
| 5. Insulation and fixing list | Insulation and boarding prepared. Walk-round of every room to record positions and gaps. | You and the builder agree the fixing list in writing. Photos of open walls taken. |
| 6. Plastering and drying | Walls and ceilings boarded and skimmed, then left to dry. | Plaster is fully dry before tiling or decorating. No more cutting into walls. |
| 7. Second fix | Kitchen units, bathroom suites, sockets and switches, radiators, internal doors, skirting. | Everything works, nothing leaks, and the dirty work above is finished. |
| 8. Flooring and decorating | Painting, tiling grout and sealant, floor finishes, final trims. | Decorating is complete before the most easily damaged finishes go down. |
| 9. Testing, certificates and snagging | Electrical and gas certificates, building control sign-off, snagging walk-round. | Paperwork in hand and defects listed before the final payment. |
Stage by Stage
1. Survey, plans and permissions
Start with the building, not the finishes. Look for damp, leaks, cracks, roof and chimney problems, old wiring and old plumbing. Separate essential work (structure, damp, roofing, electrics, plumbing) from nice-to-haves (finishes, layout changes, landscaping), and pay for the essentials first. Then check whether you need planning permission or Building Regulations approval, and get quotes against a written brief. Our guides on finding a good builder and the 10 questions to ask a renovation company cover the hiring side, and the planning permission guide covers consents.
2. Strip-out
Strip-out is when a house tells you the truth. Photograph every wall, floor and ceiling as it is exposed. If something unexpected turns up, such as damp, rot or old pipework, deal with it now. A repair done at this stage is a line on the quote; the same repair after plastering is demolition.
3. Structure and weatherproofing
Structural changes come before anything delicate. That means wall removal and steels, extension groundworks and the roof and windows needed to close the building in. Internal trades should not start until the house is weathertight, because water on fresh plaster or electrical first fix undoes everything that follows. If the structural work needs Building Control inspections, book them in advance so the site is not left waiting.
4. First fix
First fix is everything that goes inside walls, floors and ceilings: electrical cables and back boxes, water and waste pipework, heating pipes and any ventilation ducting. It happens before plastering so nothing is chased out of finished walls. Gas work must be done by a Gas Safe registered engineer, and electrical work in a home is covered by Part P of the Building Regulations. Your electrician and plumber both need your final layout at this point, which is why decisions come before first fix, not after.
5. Insulation and the fixing list
This is the pause that many projects skip. Once first fix is done and before the walls are boarded, walk every room with the builder. Record where every socket, switch, radiator, light and appliance goes, check door openings, look for gaps in insulation and fire stopping, and take photos. Moving a socket now is minutes; moving it after plastering is a repair job.
6. Plastering and drying
Plastering only starts once first fix is signed off. Boards go up, walls and ceilings are skimmed, and then the plaster has to dry. It can look dry well before it is, and painting too early traps moisture and causes patchy finishes. Follow your plasterer's advice on when to apply a thinned mist coat, and keep the house ventilated while it dries. Tiling also has to wait for the walls to be ready.
7. Second fix
Second fix is the visible stage. Kitchen units and worktops, bathroom suites, sockets and switches, radiators, internal doors and skirting boards all go in. The house starts to look finished here, but there is usually still a few weeks of work left. Electricians and plumbers return to connect and test, and kitchens often need a final templating visit before stone or solid worktops are cut.
8. Flooring and decorating
Decorating and floors are done last among the messy jobs so they do not get damaged by the rest. The usual rule is that the dustiest and wettest work finishes first, then painting, then the most easily damaged floor finishes such as carpet. Check with your builder how they sequence flooring and skirting in each room.
9. Testing, certificates and snagging
Before handover you want the electrical certificate, the gas safety certificate where relevant, Building Control completion documents and any guarantee paperwork. Then do a proper snagging walk-round, room by room, listing every defect in writing with a date to put them right. Keep back the final payment, or a retention, until the list is cleared. Our builder guide explains how to structure stage payments around this.
Decisions to Make Before First Fix
Many delays are not building problems at all. They are decisions that were not made in time. The following should be fixed before the electrician and plumber start first fix:
- Kitchen layout and appliances. Sockets, waste, water and extraction all depend on it. Changing the layout after first fix usually means delays and extra cost.
- Bathroom layout and fittings. Position of the shower, bath, toilet and basin, and whether you want a walk-in shower, wet room or a heated floor.
- Socket, switch and light positions. Think about where furniture, TV, desk and beds will go, plus outdoor and loft lighting.
- Heating. Radiator positions and sizes, underfloor heating, boiler location and controls.
- Door and window sizes. Particularly where openings are moving or being widened.
- Floor build-up. Final floor heights affect door clearances and thresholds.
- Tile and finish choices. They do not all have to be bought at once, but you need to know their thickness and size to set up the substrate.
Lead Times to Plan Around
Some things take weeks to arrive or be approved. Ordering them late is the most common cause of a gap in the programme. Treat these as rough planning figures, since suppliers and councils vary:
| Item | Typical lead time | Why it matters |
|---|---|---|
| Planning decision | Around 8 weeks for a standard application, longer if complex | Nothing structural starts until it is granted. See our planning guide. |
| Building Regulations (Full Plans) | A few weeks for approval | Gives certainty before work starts. A Building Notice is quicker but riskier. |
| Kitchen units | Commonly 4 to 10 weeks, longer for bespoke | Layout must be final before first fix, and units on site before second fix. |
| Windows and external doors | Several weeks, often more for made-to-measure | The house cannot be weathertight without them. |
| Worktops | Made after the units are fitted and measured | Allow extra days between kitchen fit and worktop install. |
| Good tradespeople | Often booked weeks ahead | Book trades for the stage they are needed, not when the previous stage ends. |
Ask your builder for a short ordering schedule: what needs ordering, by what date, and what it holds up if it is late.
Which Room First If You Are Living There
If you are staying in the house, the main rule is not to lose your kitchen and your only bathroom at the same time. A workable pattern is to keep one usable bathroom and a basic kitchen setup throughout, finish the first room, and then start the second. Where a full renovation includes structural work, living elsewhere for the messiest weeks is often easier and quicker. Our guide to living at home during a renovation covers how to make that decision and what to expect.
Older Manchester Homes
Victorian and Edwardian terraces and 1930s semis change a few steps in the sequence:
- Deal with damp before plastering. Plastering over an unresolved damp problem hides it for a while and then it comes back. Find the cause first.
- Expect surprises at strip-out. Old lead or steel pipework, outdated wiring and uneven floors often need extra work. Budget a contingency of 10% to 15%, and more if the house has never been renovated.
- Think about breathable finishes. Solid-wall houses behave differently to modern cavity walls. Ask your builder to explain what plaster and paint suit the walls.
- Neighbours and shared walls. If the work touches a party wall, the Party Wall etc. Act 1996 may require notice to your neighbours before work begins.
- Conservation areas. Some Greater Manchester areas have extra rules for windows, roofs and extensions, so check before ordering.
Our Victorian terrace renovation guide goes into more detail on typical problems, and the full house renovation page shows how a whole-house programme is managed.
Order Mistakes That Cost Money
- Plastering before first fix is signed off, which leads to cutting back finished walls.
- Ordering the kitchen after strip-out, leaving the site with nothing to do for weeks.
- Changing the layout after first fix, which means moving pipes and cables that are already in place.
- Painting on damp plaster, which causes peeling and patchy finishes.
- Laying the best floors early, then watching them be damaged by later trades.
- Making the final payment before certificates and snagging, which removes your leverage.
- No contingency, so every discovery becomes an argument about money. See our guide to insurance and financing for how to plan the budget.
