A whole-property refurbishment brings many trades through the same rooms. We price each part of the work as its own line, plan the trades against calendar weeks, and run the job as one programme, from the roof to the skirting boards.

Costs
What a refurbishment costs in London
For a 75 m² flat at a standard finish, without moving walls, the planner gives £82,000 to £130,000 including contingency and VAT. At an upgraded finish it comes to £125,000 to £198,000.
- What is behind the walls
- Old wiring, lead or iron pipes, and damp all add work that cannot be seen until strip-out. We show these as provisional sums until they are known.
- The roof and windows
- Renewing a roof or replacing windows adds scaffolding and specialist trades, and are often the largest single lines.
- Layout changes
- Moving walls adds a structural engineer, Building Control and more making good.
- Options
- Joinery and other upgrades are priced separately so you can add them without re-pricing the whole job.
Estimated total including VAT
£82,000 to £130,000
£68,000 to £108,000 before VAT

Consents and regulations for refurbishments
- Leasehold flats
- Most leases need the freeholder’s written consent before alterations. Check the lease early, as consent can take weeks.
- Building Control
- Needed for structural changes, new drainage, replacement windows and roofs, and electrical work not certified by a registered electrician.
- Roofs and insulation
- Replacing a large part of a roof usually means bringing its insulation up to current standards.
- Conservation areas and listed buildings
- Changes to windows, doors and roofs may need planning permission, and any works to a listed building need listed building consent.

Really professional service, we have ordered bespoke joinery units for my parents house, made with spray painted MDF with routed handles and also soft close drawers internally for the wardrobes. We also ordered a bespoke tv unit. Really great work, we loved it!

Questions
Questions about refurbishments
How much does it cost to refurbish a flat in London?
From our planner: a 50 m² one-bedroom flat at a standard finish comes to £54,000 to £87,000, and a 75 m² two-bedroom flat to £82,000 to £130,000, including contingency and VAT.
How much does a full house renovation cost in London?
A 120 m² house at an upgraded finish, with some walls moved, comes to £204,000 to £323,000 including contingency, fees for the structural changes and VAT. Roofs, windows and extensions are usually priced on top.
How long does a house refurbishment take?
It depends on scope. One recent house refurbishment, including a new slate roof, rooflights, windows and joinery, was programmed at 16 weeks on site.
Can we live in the property during the work?
Sometimes, with phasing. A full refurbishment with services renewed is usually simpler with the property empty.
