Quick Answer: How Much Does a Home Renovation Cost in the UK?

What Affects Home Renovation Cost?

Property Condition

A property needing significant structural repair, damp treatment, or rewiring before any cosmetic work can begin will cost considerably more than a sound property needing only decorative updates.

Specification Level

Budget, mid-range, and premium fixtures and fittings can vary the cost of an identical room by two to three times, so setting a clear specification level early helps control the overall budget.

Structural Changes

Removing internal walls, moving plumbing or electrical points, or altering the property’s layout adds significant cost beyond a straightforward like-for-like refresh.

Location

Labour costs vary regionally across the UK, with London and the South East generally commanding higher trade rates than other regions.

How to Budget for a Home Renovation

Get detailed, itemised quotes from at least three tradespeople or contractors before committing to a budget
Add a contingency of 10 to 20 percent on top of quoted costs, particularly for older properties where hidden issues are common once work begins
Prioritise structural and safety related work, such as rewiring or damp treatment, before cosmetic upgrades
Decide early which rooms are must-do versus nice-to-have, so the budget can flex if unexpected costs arise
Factor in temporary accommodation or storage costs if the renovation will make parts of the property unliveable

DIY vs Hiring a Main Contractor

Managing a renovation yourself, hiring individual tradespeople directly, can save the 10 to 20 percent margin a main contractor typically charges for project management, but requires significantly more time, coordination, and risk tolerance for scheduling conflicts between trades. A main contractor suits larger, more complex renovations where coordinating multiple trades yourself would be impractical alongside other commitments.

Where to Save Money on a Home Renovation

Keep existing layouts where possible, since moving plumbing and electrics adds significant cost
Mix premium statement items, such as a feature tile or worktop, with budget choices elsewhere in the same room
Time work outside peak renovation season, typically spring and early summer, when tradespeople may offer better rates
Do straightforward preparation work yourself, such as clearing rooms or basic demolition, where safe and permitted

Frequently Asked Questions

How long does a full home renovation take?

A full house renovation typically takes three to six months depending on scope, property size, and whether structural work is involved, while single room renovations usually take two to four weeks.

Do I need planning permission for a home renovation?

Cosmetic and like-for-like renovation work generally does not need planning permission, but structural changes, extensions, or work on a listed building may require permission, so checking with your local authority before starting is worthwhile.

Should I renovate room by room or all at once?

Renovating all at once is generally more cost effective through shared scaffolding, skip hire, and contractor mobilisation, but room by room renovation spreads the cost and disruption over a longer period, which suits some budgets and living situations better.

What renovation adds the most value to a house?

Kitchen and bathroom renovations are consistently reported as adding the most resale value relative to their cost, followed by improvements to energy efficiency and general property condition.

Can I live in my house during a renovation?

This depends on the scope of work. Single room renovations are usually manageable while living in the property, but full structural renovations, particularly those affecting plumbing, heating, or multiple rooms at once, often require temporary alternative accommodation.

Expert Insight

Renovation contractors consistently report that unexpected costs on older properties, particularly around damp, wiring, and structural timber, are the most common cause of budgets overrunning, which is why a realistic contingency fund matters more on period properties than on newer builds.

Final Thoughts

Home renovation costs vary enormously based on property size, condition, and specification, but understanding the typical ranges by room and property type makes it much easier to set a realistic budget from the outset. Building in a sensible contingency protects against the most common cause of renovation budget stress.

Planning a renovation? Get itemised quotes rather than single lump sum figures, so you can see exactly where your budget is being spent and identify areas where costs could be trimmed if needed.
