Sound familiar?

The costliest renovation mistake? The right work in the wrong order.

New floors laid before the old pipework is replaced. Fresh plaster before the rewire. A brand new kitchen fitted before anyone has decided where the heating goes.

None of those jobs is wrong on its own. Done in the wrong order, they mean opening up finished walls, floors and ceilings a second time and paying for the finish twice. On a whole house renovation, we plan the structure, plumbing, electrics, heating and finishes together, so every stage is done once.

Plan my renovation in the right order
  • Heating before flooring

    New floors never have to come up again to reach the pipes.

  • Electrics before plastering

    Freshly plastered walls aren't chased out later for a cable.

  • Plumbing before the kitchen

    Units and worktops stay untouched once they're fitted.

  • Structure before decorating

    You only pay for the final finish once.

What's Included

  • Full home renovation in Cardiff managed from first survey to handover
  • Structural work, rewiring, plumbing, heating and finishing by one team
  • Energy efficiency upgrades planned in while walls and floors are open
  • One fixed-price quote and a staged programme before work starts

Home Renovation in Cardiff, Planned as One Programme

Cardiff's housing runs from pre-1920s terraces in Cathays, Roath and Canton to inter-war semis in Llanishen and Whitchurch, and newer estates further out. The older the property, the more sits behind the plaster: solid walls, original pipework, wiring that has been added to over decades. A renovation on a house like that is really several jobs stacked on top of each other, and the order they happen in decides the final bill.

How the programme runs

Strip-out and structural work first, then first fix while walls and floors are open: wiring, pipework, heating and insulation. Plastering and screeding next, and finally second fix, when the kitchen, bathroom, flooring and decorating go in onto finished surfaces. You get the whole sequence in writing with your quote, so you know what happens in which week.

The energy work most renovations miss

A renovation is the cheapest moment of the property's life to insulate it. With floors up and walls open, loft and wall insulation, a heating upgrade or the groundwork for solar costs a fraction of what it does as a separate job later. We cover all of it in-house, so it's simply built into the same programme rather than quoted by someone else.

Welsh planning and building regulations

If the renovation includes structural changes, an extension or a loft conversion, it follows Welsh rules rather than the English ones, and the permitted development limits differ. We confirm what your Cardiff property is allowed and handle the building control side before any drawings are finalised.

Case study

Full Property Refurbishment

Kitchen, bathroom and extension work completed alongside an energy efficiency upgrade, all run as one project by one team. See the house refurbishment before and after.

This full property refurbishment project brought three separate jobs under one programme: a new kitchen, a new bathroom and extension work, with an energy efficiency upgrade carried out at the same time rather than bolted on afterwards.

Running it as one job is what made the sequence work. The extension shell went up first, pipework and wiring were moved while walls and floors were still open, the energy efficiency work went in at that point, and the kitchen and bathroom were fitted last onto finished surfaces. Nothing had to be opened up twice.

We required an urgent new boiler installation due to the old one breaking down and being unrepairable. Greentek Energy supplied and fitted a new one at very short notice so our tenants could have heating and hot water again. We are very grateful to Greentek Energy and would recommend them highly.

What it costs

What a Full House Renovation Costs

Every full house renovation is quoted from a proper survey and an agreed scope, broken down stage by stage, so you can see exactly what each part of the work costs before you commit.

  • Property size and condition

    How much of the old wiring, pipework and fabric needs replacing once we look properly.

  • Rooms involved

    Which rooms are in scope and how far the work goes in each one.

  • Structural work

    Knocking through, extensions, loft work and anything that needs steels or building control sign-off.

  • Standard of finish

    The kitchen, bathroom, flooring and fittings you choose, which is usually the single biggest variable.

Every quote includes

  • A free site survey, with no obligation to go ahead
  • A fixed price agreed in writing before any work starts
  • Materials, labour and making good, in one price
  • Our own team throughout — no subcontractors marking the job up
  • A written workmanship warranty on completion

We don't quote over the phone from a postcode — the survey is what makes the price fixed rather than an estimate that moves. Finance is available through Ideal4Finance, subject to status.

Frequently asked questions

How much does a full home renovation cost in Cardiff?+
It depends on the property's condition, the rooms involved, any structural work and the standard of finish, not on the postcode. We survey the whole house, agree the scope and give one fixed-price quote in writing.
How long does a full renovation take?+
Most whole-house projects run over several weeks to a few months, depending on size and scope. You get a staged programme with the quote, so you know which trade is on site in which week.
Can you add energy upgrades to a renovation in Cardiff?+
Yes. With floors up and walls open, insulation, a heating upgrade or solar can be built into a Cardiff renovation far more cheaply than added later, and the same in-house team does both.
Can we stay at home during a renovation in Cardiff?+
Often, with the work phased around you, but it depends on the scale. We discuss access, safety and disruption at the survey before anything is agreed.
Do you cover Newport and Bridgend?+
Yes. The same team that renovates properties in Cardiff also works in Newport, Bridgend, Neath and Merthyr Tydfil, with the same survey, fixed price and warranty.
Do you handle the planning and building regulations?+
Yes. Where structural work, an extension or a loft conversion is involved, we confirm what Welsh planning rules allow and deal with building control as part of the project.
