Renovation Cost per m2 Costs in West Midlands

Typical West Midlands renovation cost per m2 budgets

Three planning tiers for renovation cost per m2 in West Midlands, with scope and a representative figure for each. Run your own numbers in the calculator for a tailored range.

Typical regional cost ranges

Indicative range: £300–£2,000 per m².

1. 1

   Professional fees — architect, structural engineer, project management

   On a renovation of any scale, professional fees typically run 8–15% of build cost. Architect (£40–£80/hr or 5–12% of build), structural engineer (£500–£3,000 fixed), planning consultant if needed (£800–£3,000), project manager if not self-managing (10–15% of build). These are usually MISSING from per-m² figures online — a big budget gap.

   Fair UK range: 8–15% of total build cost in professional fees on most renovations.

   Ask: Are professional fees included in your £/m² figure, or do I add them on top?

2. 2

   VAT — what's at 20%, what's at 5%, what's exempt

   Standard renovation work is at 20% VAT. But: empty homes (vacant 2+ years) qualify for 5% VAT on certain works; new builds are 0%; certain energy efficiency installs are 5%. Most online per-m² figures don't specify VAT treatment. A £1,500/m² figure can mean £1,800/m² at standard VAT.

   Fair UK range: Add 20% to ex-VAT figures unless you've confirmed reduced/zero rates apply.

   Ask: Is your £/m² figure inclusive of VAT, and at which VAT rate? Do I qualify for 5% VAT on this property?

3. 3

   Contingency — typically 10–15% of build cost

   Renovations always uncover surprises. Asbestos, rotted joists, failed electrics, hidden damp — every renovation has £3,000–£15,000+ of work that wasn't visible at quote time. Online per-m² figures NEVER include contingency. If your budget doesn't have 10–15% contingency, your renovation will run out of money mid-job.

   Fair UK range: Hold 10–15% of build cost as contingency on standard renovations; 15–20% on older properties (pre-1900) or unknowns.

   Ask: What contingency are you recommending, and have you priced for unforeseen issues like asbestos or rotted timber?

4. 4

   Per-trade rates that drive the £/m² figure

   A £1,600/m² figure includes: ~£200/m² fees, ~£600/m² shell repair (plaster, electrics, plumbing), ~£300/m² kitchen pro-rated, ~£200/m² bathroom pro-rated, ~£150/m² flooring, ~£150/m² decoration. Knowing the breakdown lets you sense-check a quote against this benchmark.

   Fair UK range: On £1,600/m² total: shell ~37%, kitchen ~19%, bathroom ~12%, flooring ~9%, decoration ~9%, fees ~12%.

   Ask: Can you give me a per-trade breakdown of your £/m² figure?

5. 5

   Works NOT typically included in £/m² (often missed)

   Per-m² figures usually exclude: external work (driveway, garden, fencing), removals/storage, temporary accommodation while work happens, soft furnishings (curtains, blinds), legal fees if listed/conservation, planning fees. Easily £5,000–£20,000 of 'extra' costs that are real and forgotten.

   Fair UK range: Add £5,000–£20,000 above the per-m² figure for these typically-excluded items.

   Ask: What's NOT included in your per-m² figure that I should budget for separately?

• Per-m² figure quoted without specifying what's included

  Why it matters: A £1,000/m² figure can mean: cosmetic refresh only, no kitchen, no bathroom, no professional fees, no VAT. A £2,500/m² figure can mean: full structural rework, premium kitchen, professional fees, VAT, contingency. Without spec, the figures are meaningless.

  Ask: What specifically does your £/m² figure include — and exclude? Can you list each major work category?

• Contractor uses £/m² as a binding quote rather than a budget benchmark

  Why it matters: Per-m² figures are useful for early budgeting; they're never accurate enough to be a binding quote on a specific property. Each property has unique conditions (existing services, structural quirks, access). If a contractor says 'I'll do it at £1,500/m²' without inspecting, they're either lowballing to win the job or planning to charge extras.

  Ask: Have you done a detailed inspection, and can you give me a fixed price based on this property's actual conditions?

• No contingency in the budget conversation

  Why it matters: Any contractor or budget guide that doesn't mention contingency is misleading you. Every renovation discovers unexpected work. If your budget is exactly the quote, you're set up for stress.

  Ask: What contingency do you recommend, and what's typical for unforeseen issues on a property of this age?

• Significant variation between online £/m² figures and contractor quotes

  Why it matters: Online articles often quote outdated figures (pre-2022 inflation), unclear scope, or American 'per sq ft' converted naively. Trust contractor quotes (with line items) over Google searches.

  Ask: Can we get this quoted by 3 contractors based on actual scope, rather than relying on £/m² benchmarks?

• VAT treatment unclear

  Why it matters: 20% VAT on a £150,000 build is £30,000. If the figure is ex-VAT and you assume inc-VAT, you're £30k out of pocket. The empty-home 5% VAT rule, if it applies, can save you £22,500 on the same project — but most builders don't ask.

  Ask: Are quotes inclusive or exclusive of VAT? Have you checked if I qualify for 5% reduced rate (empty homes) or any energy efficiency exemptions?

• No mention of professional fees as a separate line

  Why it matters: Professional fees (architect, engineer, project management) are 8–15% of build cost. If they're missing from your budget, you've under-budgeted by £8k–£20k on a typical project.

  Ask: What professional fees are included or excluded from your £/m² figure?

• Budget excludes external works and services

  Why it matters: Driveways, garden, fencing, drainage works, gas meter relocation, electrical capacity upgrade — these can add £10,000–£30,000 and are often outside the renovation £/m² figure.

  Ask: What external works (driveway, garden, services) are needed and included?

1. 1. Have you completed renovations of similar scope and £/m² in this region in the last 2 years?

   Why it matters: Direct experience of comparable projects is the strongest competence signal. 'I've done lots of renovations' is too vague — pin it down to similar scope, similar property age, similar region.

2. 2. Can you provide a per-trade and per-room breakdown of your £/m² figure?

   Why it matters: A reputable contractor can break down £/m² by: shell repair, services, kitchen, bathroom, flooring, decoration, fees, VAT, contingency. Vague total figures hide where money goes.

3. 3. What contingency do you recommend, and how is it drawn down during the project?

   Why it matters: Industry norm: 10–15% contingency, drawn down only with written approval after specific issues are identified. 'We'll just see' is not a contingency policy.

4. 4. Are you a member of the FMB or TrustMark, and do you offer Insurance-Backed Guarantees?

   Why it matters: FMB IBGs and similar warranties protect you if the contractor goes bust. Membership is verifiable on each body's public register.

5. 5. What contract are you proposing — JCT Minor Works, JCT Home Owner, or your own terms?

   Why it matters: JCT contracts are industry standard and define payment, variations, and dispute resolution. For projects over £30k, JCT is essentially mandatory for adequate protection.

6. 6. What's your payment schedule, and what milestones trigger each stage?

   Why it matters: Stage payments tied to verifiable milestones protect you. Calendar-based payments don't. For larger projects, 5–10% retention held back for 6–12 months post-completion is standard.

7. 7. Who handles each major trade (electrics, plumbing, structural), and are they certified?

   Why it matters: Electrics need NICEIC/NAPIT (Part P). Gas needs Gas Safe. Structural needs IStructE. A single trader doing all of these on a £100k project is a red flag.

8. 8. How will you protect occupied parts of the house and store materials?

   Why it matters: If you're living in part of the house during work (common), dust separation, secure material storage, and access management matter. Vague answers mean misery.

9. 9. What's the warranty on the workmanship, and is it insurance-backed?

   Why it matters: Industry norm: 10-year insurance-backed warranty for structural; 12–24 months for other workmanship. For larger projects, an IBG or NHBC-style cover is essential.

10. 10. Are you VAT registered, and what's your public liability cover?

    Why it matters: VAT registration matters for invoicing and warranty enforcement. Public liability of £5M minimum is industry norm for £100k+ projects. Ask to see certificates.
