Order of works
How a house refurbishment is sequenced
Survey and scope
We inspect the property, agree what stays and what goes, list every room and trade in writing, and in homes built before 2000 check whether materials to be disturbed may contain asbestos.
Strip out and structure
Old fittings come out, and any wall changes or repairs are made and signed off.
First fix
Plumbing, heating, electrics and drainage are run in while walls and floors are open.
Plaster and second fix
Plastering is followed by joinery, tiling, fitting of kitchens and bathrooms, sockets and radiators.
Decoration and handover
Painting, flooring and a final snagging walk-through finish the job.
Flats
Flat refurbishment: leases, neighbours and access
Refurbishing a flat has extra rules. Many leases require written consent from the freeholder before structural changes, new flooring over bare boards, or altered plumbing and electrics. Building management may also set working hours and require protection for lifts and communal areas.
Flats also mean noise limits, restricted parking and deliveries carried up stairs, all of which we plan into the programme. Tell us early if you rent, let, or share a building, so access and timings are agreed before work begins. For wider budgeting, try our refurbishment cost calculator.
Is it time?
Signs your home needs more than a cosmetic refresh
- Damp, mould or recurring leaks that keep coming back
- Old wiring, a dated fuse box or too few sockets
- Tired radiators, a failing boiler or poor water pressure
- Cracked or uneven plaster and floors
- Layout that no longer suits how you live
- Kitchen and bathroom both at the end of their life
Planning ahead
Planning your London home renovation
Good renovation starts with a clear brief and a realistic order of rooms. Decide which rooms matter most, what must be done first for safety or dryness, and what can wait for a later phase. Heating, wiring and pipework come before finishes, because they are the hardest and most expensive things to change once walls are decorated.
Choose tiles, flooring and fittings early, as lead times can hold up the schedule. See our kitchen and bathroom refurbishment pages, or book a free survey to get a written scope for the whole house.
Common surprises
What older London properties often reveal
Old wiring
Rewiring may be needed to meet current safety rules before new sockets and lighting go in.
Hidden damp
Damp behind plaster or under floors needs the cause fixed, not just covered up.
Dated pipework
Lead, steel or leaking pipes are best replaced while floors and walls are open.
Uneven structure
Old walls and floors are rarely level, which affects tiling, kitchens and joinery.
Questions
Home refurbishment in London: your questions
How long does a house refurbishment take in London?
It depends on the size of the property and how much is being changed. A light refresh can take a few weeks, while a full house refurbishment with new heating, electrics and kitchen or bathrooms usually takes several months. We give a programme in writing after the survey.
Do I need planning permission to refurbish my house?
Internal refurbishment usually does not need planning permission, but a listed building needs listed building consent for internal or external works that affect its character, and leasehold flats usually need the freeholder's consent under the lease. Structural changes, new drainage, new circuits, a new boiler or windows, and loft or rear extensions are usually subject to Building Regulations. We flag what is likely to apply before work starts, and your council can confirm.
Can I stay in my home during a refurbishment?
Often yes for partial work, especially if one room is done at a time. For a full refurbishment, with water, power and heating off for periods, many people move out or stay with family. We can phase the work so you keep a kitchen or bathroom.
What is the difference between renovation and refurbishment?
Refurbishment usually means cleaning up, repairing and updating what is there. Renovation often means restoring an older or neglected property, and can include structural repair. In practice the terms overlap, and we scope each job room by room.
Do I need a freeholder's permission to refurbish a leasehold flat?
Often yes. Many leases require written consent for structural changes, flooring changes and work on pipes or wiring. Check your lease and ask the freeholder or managing agent before work starts. We can supply a scope of works to support your application.
Should I refurbish in stages or all at once?
Doing everything at once is usually quicker overall and avoids repeated disruption, as trades are coordinated. Staging suits tighter budgets or people living in the property. Either way, the plumbing, heating and electrics should be planned for the whole house first.
How do I get a written estimate for refurbishment?
We visit, measure and agree the scope with you, then give a written estimate. The more decisions you have made on layout and finishes, the more accurate it is. For a first idea, use our refurbishment cost calculator or the pricing page.
