How Much Does a Home Renovation Cost in Perth? 2026 Price Guide
Getting Realistic About Renovation Costs in 2026
"How much will it cost?" is the first question every homeowner asks — and rightly so. A renovation is a significant investment, and you deserve a clear, honest answer before you commit.
The truth is that costs vary depending on the scope, specification, access, and condition of your property. But after 15+ years delivering home renovations across Perth and Perthshire, we can provide realistic price ranges that help you plan with confidence.
This guide covers the most common renovation types we carry out, with typical 2026 prices for the Perth area.
Kitchen Renovation Costs in Perth
The kitchen is the most popular renovation we're asked to deliver. Costs vary enormously depending on the quality of units, worktops, and appliances chosen.
| Scope | Typical Cost (2026) |
|---|---|
| Budget refresh (new doors, worktops, handles) | £3,000 – £6,000 |
| Mid-range full kitchen (supply and fit) | £8,000 – £15,000 |
| Premium kitchen with island and quartz worktops | £15,000 – £30,000+ |
These prices include supply, installation, plumbing, electrics, tiling, and finishing. The biggest cost variables are worktop material (laminate vs quartz), appliance quality, and kitchen size.
A mid-range kitchen renovation in Perth typically takes 2–3 weeks from strip-out to completion. We manage the full project including all trades.
What Adds Cost
- Relocating plumbing or gas — moving the sink, dishwasher, or hob from their current position
- Structural changes — removing a wall to create open-plan living
- Premium appliances — upgrading from mid-range to high-end brands
- Underfloor heating — a popular add-on, especially in ground-floor kitchens
Bathroom Renovation Costs in Perth
Bathrooms are the second most common renovation we carry out. Even a modest bathroom upgrade delivers significant quality-of-life improvement and property value.
| Scope | Typical Cost (2026) |
|---|---|
| Basic refresh (new suite, tiles, flooring) | £3,000 – £5,000 |
| Full bathroom renovation | £6,000 – £12,000 |
| Luxury wet room with underfloor heating | £10,000 – £18,000 |
Our bathroom renovation service includes design consultation, full installation, plumbing, tiling, electrics, and all finishing work.
What Adds Cost
- Walk-in shower enclosures (more tiling, more waterproofing)
- Wall-hung vanity units and toilets (require concealed frames)
- Underfloor heating (electric mat systems are the most cost-effective)
- Large-format porcelain tiles (stunning results but more labour-intensive)
- Heated towel rails and LED mirrors
House Extension Costs in Perth
An extension is the most significant renovation you can undertake — and the one that adds the most value to your property. In Perth, extensions typically cost between £1,500 and £2,200 per square metre, depending on specification and complexity.
| Type | Typical Cost (2026) |
|---|---|
| Single-storey rear extension (15–25 sqm) | £25,000 – £50,000 |
| Two-storey extension | £45,000 – £80,000 |
| Wrap-around extension | £50,000 – £100,000+ |
| Sunroom or garden room | £15,000 – £35,000 |
Our house extension service covers everything from architectural design and planning applications through to construction and interior finishing.
What Affects Extension Costs
- Foundations — ground conditions in Perthshire vary. Rocky ground or high water tables increase foundation costs.
- Structural steel — opening up large spans requires steel beams (RSJs), adding £1,500–£5,000 depending on size.
- Roofing type — flat roofs are cheaper; pitched roofs with tiles cost more but match existing properties better.
- Glazing — bifold doors, skylights, and large windows are premium features but transform the space.
- Internal specification — a basic plastered shell costs less than a fully finished kitchen-diner with underfloor heating.
Garage Conversion Costs in Perth
A garage conversion is one of the best value-for-money renovations available. You're converting an existing structure — the walls, roof, and foundations are already in place — so costs are significantly lower than building from scratch.
| Scope | Typical Cost (2026) |
|---|---|
| Basic conversion (insulation, plasterboard, flooring, electrics) | £12,000 – £18,000 |
| Premium conversion with en-suite | £18,000 – £28,000 |
| Full self-contained studio/annex | £25,000 – £40,000 |
Garage conversions rarely need planning permission in Scotland (they're usually classed as Permitted Development), making them one of the quickest and simplest ways to add usable space.
Loft Conversion Costs in Perth
A loft conversion adds a full additional room — typically a bedroom with en-suite — using your existing roof space. Costs depend heavily on the type of conversion and the existing roof structure.
| Type | Typical Cost (2026) |
|---|---|
| Velux/rooflight conversion | £20,000 – £35,000 |
| Dormer conversion | £30,000 – £50,000 |
| Hip-to-gable conversion | £40,000 – £60,000 |
Loft conversions typically require a building warrant in Scotland and may need planning permission depending on the type and scale.
What Factors Affect Overall Renovation Costs?
Regardless of the type of renovation, several factors influence the final price:
- Specification level — budget, mid-range, or premium materials and finishes. The gap between budget and premium can be 2–3x on the same project.
- Structural work — removing walls, adding steel beams, underpinning foundations. Always get a structural engineer's assessment first.
- Access — difficult access (narrow lanes, rear-only access, upper floors) increases labour time and material delivery costs.
- Services — relocating plumbing, gas, or electrics is one of the most common "hidden" cost additions. It's rarely hidden if you get a proper survey first.
- Age and condition — older Perth properties often reveal surprises once work starts: damp, asbestos, outdated wiring. A good builder accounts for contingency.
- Planning and warrants — some projects require building warrants or planning permission. Application fees are modest (typically £200–£500) but the design work needed can add cost.
How to Get an Accurate Quote
Every property is different. Online calculators and per-square-metre guides give useful ballpark figures, but the only way to get an accurate price is to have a qualified builder visit your home, assess the site, and discuss your requirements in detail.
At Marshall & Co, we provide detailed, itemised estimates with no hidden costs. We break down every element — materials, labour, plant hire, waste disposal — so you can see exactly where your money goes.
We also identify potential risks and include realistic contingency recommendations. Our goal is zero surprises once work begins.
