Buy-to-Let Refurbishment Costs 2025: Complete Budget Guide for UK Landlords
Accurate refurbishment budgeting is the difference between profitable investments and cash-draining disasters. This guide provides real contractor quotes across all common refurbishment scenarios, from light cosmetic refreshes to full gut renovations, with regional variations and hidden cost warnings.
Amateur landlords routinely underestimate refurbishment costs by 40-60%, destroying investment returns before a single tenant moves in. Professional investors use systematic cost databases built from actual contractor quotes, adjusted for regional variations and project complexity.
This guide provides that database. All costs are from Q4 2025 quotes across Midlands, North, and London markets. Use these as baseline estimates, then obtain three quotes for your specific project.
The 25% Rule
Whatever your initial refurbishment estimate, add 25% contingency. Projects overrun due to hidden issues (rotten joists under vinyl, additional electrical work for compliance, asbestos discovery). The 25% buffer prevents emergency cash calls and maintains investment viability.
Refurbishment Tiers: Quick Budget Estimates
Use these per-property estimates for initial feasibility assessment, then drill into specific item costs below for accurate budgeting.
Tier 1: Cosmetic Refresh (Rental Ready)
Property is structurally sound, systems functional. Requires cosmetic improvement to rental standard.
Typical Scope:
- Full repaint (walls, woodwork, ceilings)
- Carpet replacement (bedrooms)
- Vinyl flooring (kitchen, bathroom)
- Deep clean
- Minor repairs (touch-up grouting, door handles, etc.)
Tier 2: Standard Refurbishment
Tier 1 scope plus kitchen and bathroom replacement, plus addressing maintenance issues.
Additional Scope vs Tier 1:
- Kitchen replacement (budget range)
- Bathroom suite replacement
- Boiler service/repairs as needed
- Minor electrical compliance work
- External maintenance (guttering, minor pointing)
Tier 3: Full Renovation
Gut renovation including rewire, replumb, new heating system, upgraded kitchen/bathrooms.
Full Scope:
- Complete rewire (consumer unit, sockets, lighting)
- Full replumb (new pipework, radiators, boiler)
- Quality kitchen installation
- Full bathroom(s) installation
- All flooring replaced
- Complete redecoration
- External repairs as needed
Item-by-Item Cost Breakdown

EPC Upgrade Costs (2028 Compliance)
From 2028, rental properties must achieve EPC rating C or above. Budget for these upgrades now.
Critical: Factor EPC Costs Into Offer Price
Properties currently rated D or E require £5k-£15k investment to reach C rating. This cost must be deducted from your offer price - it's not optional, it's a legal requirement for continued letting from 2028.
Upgrade Measures by Current Rating
Rating E → C (Typical Cost: £8,000-£15,000)
- Loft insulation (270mm): £400-£800
- Cavity wall insulation: £1,200-£2,000
- Condensing boiler replacement: £2,500-£3,500
- Double glazing (if single glazed): £5,000-£10,000
- Cylinder insulation jacket: £40-£80
- Thermostatic radiator valves: £300-£600
- Low-energy lighting: £150-£300
Rating D → C (Typical Cost: £4,000-£8,000)
- Loft insulation top-up: £300-£600
- Room-in-roof insulation: £800-£1,500
- Secondary glazing (if double-glazing not viable): £2,000-£4,000
- Heating controls upgrade: £400-£800
- Solar PV panels (4kW system): £5,000-£8,000 (rarely cost-effective for BTL)
ROI Note: EPC upgrades rarely increase rent proportionately to cost. Their value is in legal compliance (avoiding £5k+ penalties) and maintaining lettability post-2028. Treat as mandatory compliance cost, not value-add improvement.
Hidden Costs That Destroy Budgets
These costs aren't in contractor quotes but must be budgeted. They typically add 15-25% to headline refurb costs.
Skip Hire & Waste Removal
8-yard skip: £200-£350 per hire. Expect 2-3 skips for full refurb
Budget: £400-£1,000 per project
Scaffolding
Required for any external work above ground floor
Budget: £600-£1,200 per month hire
Building Control Fees
Required for structural work, electrical rewire, new bathrooms
Budget: £400-£1,500 depending on scope
Utilities During Works
Electricity, water for contractors. Standing charges even when vacant
Budget: £150-£400 for 8-12 week project
Snagging & Remedials
Touch-ups, fixing contractor errors, items missed from original quote
Budget: 5-10% of total contractor costs
Professional Fees
Architect, structural engineer, project management if not DIY
Budget: £1,500-£5,000 for complex projects

Frequently Asked Questions
Should I get three quotes for every item?
For major works (kitchen, bathroom, rewire) yes - three quotes minimum. For minor items (decorating, flooring) two quotes is acceptable if you have good contractor relationships. Single quotes are dangerous - you have no price benchmark and no negotiating leverage.
Can I save money doing the work myself?
Potentially yes, but factor in your time cost and skill level. Professional decorators complete a room in 1-2 days that might take you a week. Calculate your effective hourly rate - if you're saving £500 but spending 40 hours, you're working for £12.50/hour. Gas, electrical, structural work must be certified - don't DIY these trades.
How long does a typical refurbishment take?
Cosmetic refresh: 2-3 weeks. Standard refurb (kitchen, bathroom): 6-8 weeks. Full renovation: 12-16 weeks. Always add 25% buffer to contractor timescales. Delays cost money in lost rent and holding costs. Factor void period realistically when calculating ROI.
Should I use cheap or quality materials for rentals?
Use budget-to-mid range materials that prioritize durability over aesthetics. Cheap laminate flooring that needs replacing in 3 years is false economy. Mid-range laminate lasts 7-10 years and costs only 20% more. Kitchen/bathroom: budget ranges are fine - tenants care about functionality, not brand names. Avoid luxury finishes - they don't increase rent proportionately.
What's the best way to pay contractors?
Never pay 100% upfront. Standard terms: 10% deposit, 40% at halfway point, 40% on practical completion, 10% retention for 4 weeks post-completion. This protects you against poor work or contractors disappearing. Get everything in writing. For major works (over £10k) consider JCT contract terms or escrow arrangements.
Do refurbishment costs qualify for tax relief?
Repairs and maintenance: yes, fully deductible against rental income. Improvements and upgrades: no immediate relief, but they increase your capital base (reduces CGT on sale). Kitchen/bathroom replacement is usually classed as repair if like-for-like. Structural alterations, extensions, conversions are improvements (capital, not revenue). Consult accountant for specific situations.
