Every home and brief is different, but a realistic budget starts with the scope, condition of the property, structural work, specification and access.

What does a house renovation cost in North London in 2026?
For a whole-house renovation in North London, published market guides commonly show broad planning ranges of roughly £1,500–£2,500 per m² for a mid-to-high-quality renovation. Premium finishes, complex period-property work, major structural changes or extensive bespoke joinery can take the cost higher.
This is a planning guide, not a quotation. North Star Building Solutions Limited prices each project from agreed drawings, the specification, survey information and site conditions.
Typical planning ranges
| Scope | Broad 2026 planning range | What changes the figure |
|---|---|---|
| Light internal refresh | £800–£1,200 per m² | Decoration, flooring, retained services and existing condition |
| Full renovation | £1,500–£2,500 per m² | Kitchen, bathrooms, rewiring, plumbing, plastering, windows and finish level |
| Premium or complex renovation | £2,500–£3,500+ per m² | Structural alterations, bespoke work, high-end finishes, period-property repairs and design complexity |
These are market planning ranges only. They are not North Star price promises and should be checked against real project information.

What should a renovation budget include?
- Surveys, drawings, structural engineering and planning or building-control requirements
- Strip-out, protection, skips and site set-up
- Structural alterations, steels and making-good work
- Electrical and plumbing upgrades
- Insulation, plastering, windows, doors and flooring
- Kitchen, bathrooms, sanitaryware, tiling and fitted joinery
- Decorating, external works and final handover
- A sensible contingency for hidden defects in older properties
Why costs vary so much in North London
Period homes can hide issues behind finishes. Access restrictions, parking, neighbours, party-wall matters, chimney work, damp, outdated services and structural openings all affect programme and cost. The quality of fittings and level of bespoke joinery can also change the budget considerably.

How North Star helps clients budget properly
North Star Building Solutions Limited manages renovations from initial discussion through to completion. Before starting work, we help clients clarify the scope, understand practical construction requirements and build a clearer route from survey and design to construction and handover.
The most accurate way to budget is to share the property location, photographs, approximate floor area, drawings if available, the rooms you want to change and your intended level of finish.
Frequently asked questions
Does the guide include an extension or loft conversion?
No. An extension or loft conversion should normally be budgeted separately because structure, foundations, roof work, glazing and approvals can materially change the cost.
Should I keep a contingency?
Yes. Older London homes can reveal concealed issues once work starts. The appropriate contingency depends on the age, condition and survey information for the property.
Can I get a fixed quotation?
North Star can prepare a project-specific quotation once the scope, drawings, specification and relevant site information are clear enough to price responsibly.
