House Renovations

The average cost of moving home in 2026 sits around £12,000-£15,000 once you add up estate agent fees, solicitor costs, stamp duty, removal costs, and the survey. For a property worth £350,000, stamp duty alone is £7,500. That money goes into the pockets of lawyers and the taxman — it adds nothing to your living space.

A renovation puts that money directly into your home. A well-executed full renovation typically adds 15-25% to a property's value, and you get to stay in a location you already know and like. Your children stay in the same schools, you keep your commute, and you don't lose three months to the legal chain.

The other advantage is control. When you buy an existing property, you compromise. When you renovate, you get exactly what you want — the kitchen layout, the bathroom spec, the flooring, the storage. It's your home built to your brief.

Regional Price Differences

Labour rates vary significantly across the UK. London and the South East typically run 25-35% above the national average. The Midlands and North West sit close to average. Scotland, Wales, and the North East are generally 10-15% below.

For a mid-range renovation, expect roughly:

London & South East: £55,000 – £95,000
Manchester, Birmingham & Midlands: £40,000 – £75,000
Leeds, Liverpool & North: £35,000 – £65,000
Scotland & Wales: £30,000 – £60,000

What Drives Costs Up

Asbestos: Common in properties built between 1950 and 1990. Artex ceilings, floor tiles, pipe lagging, and soffit boards can all contain asbestos. Removal by a licensed contractor costs £1,500-£5,000+ depending on the extent.

Damp: Rising damp treatment (chemical DPC injection) runs £70-£100 per linear metre. If timber has been affected by wet or dry rot, replacement costs escalate quickly — a single floor joist replacement is £300-£600.

Subsidence: If the property has movement, underpinning can add £10,000-£30,000+ to the budget.

Access: Terraced properties with no rear access mean everything comes through the front door. That adds time and labour cost — typically 10-15% on the build budget.

Single Room Renovation

1-3 weeks. A bathroom renovation typically takes 7-10 working days. A kitchen fit-out (assuming the room is already stripped and first-fixed) is 2-3 weeks. A bedroom refurbishment with plastering and decoration is 5-7 days.

Ground Floor Renovation

6-10 weeks. This covers knocking through the kitchen/dining room, installing a steel beam, new kitchen, replastering, rewiring the ground floor, new flooring, and decoration. Add 2 weeks if you're adding a downstairs WC or utility room.

Full House Renovation

12-20 weeks. Complete strip-out and rebuild for a typical 3-bed semi. The sequence runs: soft strip (1 week), structural work (2-3 weeks), first fix electrics and plumbing (2-3 weeks), plastering (1-2 weeks), second fix (2 weeks), kitchen and bathroom fit-out (2-3 weeks), decoration (2 weeks), snagging (1 week).

Period Property Renovation

16-30 weeks. Period properties take longer. Lime plaster needs 2-3 weeks drying time per coat versus days for gypsum. Sash window restoration is done on-site over several days per window. Specialist trades (stone masons, ornamental plasterers) often need to be booked months in advance. If Listed Building Consent is required, add 8-12 weeks for the application.

What Causes Delays

The biggest delay in renovations is discovery — finding problems hidden behind walls and under floors. Rotten joists, corroded pipes, outdated electrics, asbestos, damp. Budget a 10-15% contingency in both time and money. The other common delay is material lead times. Bespoke joinery, specific tiles, and specialist items can have 4-8 week lead times — order early.

Get a full survey before you commit. A RICS Level 3 Building Survey (£600-£1,500) is essential for any renovation property. A basic mortgage valuation tells you almost nothing about the condition. The survey will flag structural issues, damp, roof problems, and service defects — all of which affect your renovation budget.

Fix the structure first. It's tempting to spend the budget on a beautiful kitchen, but if the roof leaks, the damp will destroy your new plaster within two winters. Prioritise: roof, structure, damp, services, then cosmetics.

Don't move walls without checking services. That "simple" kitchen knock-through might have the mains water supply, a soil stack, gas pipes, and a consumer unit on the wall you want to remove. Survey before you quote, not after.

Insulate while the walls are open. Once you've stripped a property back to brick, it's the cheapest time to insulate. Internal wall insulation (PIR board or mineral wool) costs £40-£60 per m² during a renovation versus £80-£120 as a standalone project. The same applies to underfloor insulation — do it when the floorboards are up for the rewire.

Use a payment schedule tied to milestones. Never pay a large deposit upfront. A reasonable schedule is: 10% on signing the contract, then payments at agreed milestones — completion of structural work, first fix, plastering, second fix, and practical completion. Hold 5% retention for 3 months to cover snagging.

Keep 15% contingency. Every renovation uncovers surprises. Old properties are full of bodged repairs, hidden damage, and materials that aren't up to current standards. A 15% contingency on the total budget gives you breathing room without compromising the finished result.

Plan your kitchen and bathroom early. These rooms need precise layouts for plumbing, electrics, and ventilation. If you finalise the kitchen design after the first fix plumbing is in, you'll pay for the plumber to come back and move everything. Choose your units, appliances, and sanitaryware before work starts on site.
