Home Renovation Cost Guide: What to Budget in 2025
A full home renovation can transform a tired property into a modern, comfortable home. Whether you are renovating a period property in Worcester, updating a 1960s semi in Bromsgrove, or modernising a cottage in Malvern, this guide covers realistic costs, room-by-room budgets and how to plan your renovation effectively.
Full House Renovation Costs
A full house renovation in the UK typically costs between £500 and £1,200 per square metre depending on the extent of work and specification. For a standard 3-bedroom semi-detached house (90-100 sqm), a full renovation costs £50,000-£120,000. A larger detached property of 150 sqm could cost £75,000-£180,000. These figures include structural work, new electrics, new plumbing, plastering, kitchens, bathrooms, flooring and decoration — but not extensions.
Room-by-Room Cost Breakdown
Kitchen: £8,000-£25,000 (units, worktops, appliances, tiling, flooring). Bathroom: £5,000-£12,000 (suite, tiling, flooring, plumbing). Bedroom: £2,000-£5,000 (plastering, decoration, flooring, built-in storage). Living room: £3,000-£8,000 (plastering, decoration, flooring, fireplace if applicable). Hallway and stairs: £2,000-£5,000 (new staircase, plastering, decoration, flooring). These are mid-range specification costs including labour and materials.
Structural and Services Costs
Full rewire: £3,500-£6,000 for a 3-bed house. Full replumb: £4,000-£8,000. New central heating system including boiler: £4,000-£8,000 (gas) or £8,000-£15,000 (heat pump). Damp proofing: £2,000-£5,000. Structural repairs and steelwork: £2,000-£10,000. New roof: £5,000-£12,000. Insulation (walls and loft): £2,000-£5,000. These are essential items that should be addressed before any cosmetic work.
Specification Tiers
Basic renovation (essential repairs, standard fittings, painted walls): £500-£700/sqm. Mid-range renovation (new kitchen and bathroom, quality flooring, some structural changes): £700-£1,000/sqm. High-end renovation (bespoke kitchen, premium bathrooms, underfloor heating, oak flooring, smart home): £1,000-£1,500/sqm. The specification tier has the biggest impact on overall cost — the difference between basic and high-end can be 2-3x.
Period Properties and Listed Buildings
Renovating period properties in Worcester, Malvern, Pershore and surrounding market towns often costs 20-40% more than standard renovations. Lime mortar pointing, sash window restoration, stone or brick repairs, and heritage-sensitive materials all add to the budget. Listed building consent is required for any alterations to a listed building, adding time and cost. However, a well-renovated period property holds its value exceptionally well.
Renovation vs Extension vs Moving
A full renovation is often the most cost-effective way to transform an existing property. Moving incurs stamp duty, agent fees, legal costs and removal expenses. An extension adds space but does not address the existing property. A renovation upgrades everything — electrics, plumbing, heating, insulation, kitchens, bathrooms and living spaces — bringing the whole house up to modern standards.
Planning the Renovation Order
The correct order of work is: strip-out and demolition, structural alterations, roofing, windows and doors, first-fix electrics and plumbing, plastering, screeding, second-fix electrics and plumbing, kitchen and bathroom fitting, decoration, flooring, snagging. Getting this order wrong causes expensive rework — never decorate before first-fix services are complete.
Common Budgeting Mistakes
Underestimating by focusing on cosmetic costs while forgetting essential services (rewire, replumb, heating). Not allowing contingency (15-20% is recommended for renovations as surprises are common). Changing specification mid-project. Not getting a survey before purchase. Doing rooms piecemeal rather than a coordinated whole-house programme (more disruptive and often more expensive in total).

Frequently Asked Questions
How much does a full house renovation cost?
A full renovation of a 3-bedroom house typically costs £50,000-£120,000 depending on specification. Larger properties and high-end specifications can cost £150,000 or more.
How long does a full house renovation take?
A full renovation of a 3-bedroom house typically takes 3-6 months. Larger properties and those needing structural work can take 6-12 months.
Should I renovate or move?
Renovating is usually cheaper than moving when you factor in stamp duty, agent fees and legal costs. A renovation also lets you customise the property to your exact requirements.
What should I renovate first?
Always address structural issues and essential services first — roof, damp, electrics, plumbing and heating. Cosmetic work (decoration, flooring, kitchens and bathrooms) comes after the building is structurally sound and properly serviced.
Do I need planning permission for a renovation?
Internal renovations rarely need planning permission unless the property is listed. External changes like new windows, cladding or roof alterations may need approval depending on your location and property type.
How much contingency should I allow for a renovation?
Allow 15-20% contingency for a renovation. Older properties often reveal hidden issues once work begins — rotten joists, asbestos, failing lintels or outdated wiring that needs replacing.
