Ask anyone who has been through a full renovation what they would do differently, and the answer is almost always the same: budget properly from the start. Not optimistically. Not based on a figure a friend mentioned two years ago. Build your budget properly — with real quotes, honest contingency, and a clear picture of everything the project involves.
If you are planning a home renovation in Battersea, here is how to build a budget you can actually rely on.
Start With the Full Scope, Not the Fun Parts
Most budgets begin with the visible things — the kitchen, the bathroom, the flooring, the paint colours. Those are the easy numbers to research and the enjoyable ones to plan. But in a full renovation, they are often less than half the true cost.
The structural and behind-the-walls work is where budgets are won or lost. Rewiring, replumbing, damp treatment, replastering, new heating, structural openings, and roof repairs rarely make it onto a first draft budget, yet in older Battersea properties — much of the housing stock is Victorian — some combination of them is almost always required. Get the property surveyed and scoped before you set a number, not after.
Get Itemised Quotes, Not Ballpark Figures
A single-line quote tells you nothing. An itemised quotation shows you exactly what is included, what is excluded, and where the money goes — which means you can compare contractors on substance rather than on the bottom line alone. At JTH Projects, every quotation follows an on-site inspection and is broken down in full, because a number without detail is not a budget you can plan around.
Be wary of quotes that come in dramatically below the others. In renovation, a suspiciously low price usually means something has been left out – and you will pay for it later as an “extra”.
Build In a Real Contingency
Ask any construction builder who has spent years in older properties, and the advice never changes: put 10 to 15 percent of your budget to one side before work starts. This is not pessimism — it is experience. A house that has stood for a century does not reveal everything at the survey stage, and what sits behind plaster or beneath floorboards stays unknown until the strip-out begins. If nothing unexpected turns up, that reserve comes back to you at the end. If something does, the project simply carries on—funded, calm, and still on programme.
The Costs Almost Everyone Forgets
The build itself is only part of the picture. A budget for a home renovation in Battersea that holds up in the real world also needs to include:
- Skips, waste clearance, and welfare facilities — small weekly amounts that grow real teeth over a long project
- Building control fees and anything planning-related
- Party wall agreements, which come with the territory on Battersea’s terraced streets
- A place to stay if the noisiest phases push you out
- Storing your furniture while the house is stripped back
- The finishing touches — decoration, flooring, curtains, lighting — that every spreadsheet seems to forget
- VAT, and whether each quotation actually includes it
Taken one at a time, these are unremarkable. Taken together, they can swallow a five-figure sum—and the budgets they sink are always the ones that never saw them coming…
A Realistic Budget Is a Kindness to Yourself
Speak to anyone whose renovation turned sour, and the story is rarely about spending too much—it is about the money finishing before the house did. Build your budget on a full scope, itemised quotations, an honest reserve, and the forgotten extras, and you get the thing that makes a renovation genuinely bearable: certainty about where you stand.

Frequently Asked Questions
How much should I budget for a home renovation in Battersea?
No average will serve you well—it hinges on the property’s size, condition, and the finish you want. Book an on-site inspection instead. Ours cost nothing, and the itemised quotation that follows turns your budget from a guess into a plan.
What contingency should I hold back?
Ten to fifteen per cent. Battersea’s period homes are experts at hiding surprises, and a genuine reserve means whatever turns up gets paid for without the project missing a step.
Do quotations normally include VAT?
Not reliably — and the gap between assuming and checking has wrecked plenty of budgets. Confirm it on every quote you receive. Ours make the position clear from the outset.
Will I need a party wall agreement?
If the work involves a wall you share with a neighbour—the norm on a Battersea terrace—then in all likelihood, yes. We flag it at the first inspection so the cost and lead time never ambush you later.
