Renovation Costs: What You Really Need to Budget for in the UK
Thinking about a kitchen makeover, a new bathroom, or extending your living space? The first question that pops up is always the same – “How much will it cost?” The answer isn’t a one‑size‑fits‑all number, but you can break it down into clear chunks that make budgeting a lot less scary.
Big picture: the main cost buckets
Every renovation shares a few core expenses. Start by listing them on a spreadsheet and you’ll see where the money goes.
- Materials: From tiles and timber to cement and fittings, material choice is the single biggest driver of cost. A cheap front‑loader dryer can save £200, but splurging on high‑grade timber for a loft conversion can add thousands.
- Labour: Skilled trades don’t come cheap. A carpenter in Bristol charges around £250‑£300 a day, while a plasterer may be £200 a day. If you’re able to do some of the work yourself – for example, a dry‑fit kitchen – you can shave 15‑30% off the total.
- Planning and approvals: Extensions under permitted development rules avoid planning fees, but anything bigger needs a council application – usually £200‑£500 plus any specialist survey costs.
- Contingency: Unexpected issues (like hidden damp or foundation cracks) are almost guaranteed. Set aside at least 10‑15% of the total budget to cover them.

Tips to keep the price down without skimping on quality
Saving money isn’t about cutting corners; it’s about making smarter choices.
- Reuse what you can: Salvaged doors, reclaimed bricks or second‑hand fixtures can give character and cut material costs dramatically.
- Combine trades: Hiring a contractor who can manage multiple trades (carpentry, plastering, electrical) often reduces overhead compared to hiring each trade separately.
- Plan for a phased approach: If your budget is tight, split the project into stages – finish the structural work first, then move to finishes later.
- Shop smart: Order a little more material than you think you need (about 5% extra) to avoid costly emergency deliveries.
Don’t forget the hidden costs of a new build settling. Our piece on How Long Does It Take for a New Building to Settle? explains why you might see small cracks after the first few months and how to factor that into your budget.
Bottom line: start with a clear list of the four main cost buckets, add a healthy contingency, and look for savings in materials and labour. With a realistic budget in hand, you’ll stop guessing and start planning the renovation you actually want.
