A whole-house renovation is a planned refurbishment of an entire home, typically combining rewiring, heating, plastering, new kitchen and bathroom, flooring and decoration, and sometimes layout changes, carried out in a logical order under one project.
We take on a whole-house renovation throughout Harrow and the surrounding HA1, HA2, HA3 and HA5 postcodes, as well as in Wealdstone, Brent and Wembley. The guide range for this work in London is £58,000–£156,000 including VAT; where your project falls depends on its size, the materials you pick and how easy the site is to reach. A free survey turns that range into a fixed figure.

What are homes like around Harrow?
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
Building traditions across London also raise conservation and planning questions, so we check those for a whole-house renovation in Harrow at the survey stage.
Planning and building rules in Harrow
For anyone in Harrow, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Survey and measure
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a whole-house renovation.
Quote in writing
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a whole-house renovation are in place before the first day on site.
Finish and handover
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Questions about a whole-house renovation in Harrow
Do I need planning permission to renovate?
Most internal renovation work does not need planning permission, but it depends on what changes, your home's location, whether it is listed or in a conservation area, and which UK nation you are in. Listed buildings usually need consent for internal and external changes. Altering windows, adding dormers or changing the outside appearance in a conservation area may also need permission. We check before quoting.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
Which parts of a renovation need building regulations approval?
Several parts of a renovation fall under building regulations, including rewiring and new circuits, new boilers and heating systems, structural changes such as removing walls, replacement windows and changes to drainage. Some of this is self-certified by suitably registered trades, and some needs building control approval. In Scotland a building warrant may be needed for certain works. We arrange the right approvals and certificates.
Can you combine a whole-house renovation with other work?
Yes. Because we manage several trades under one contract, we can plan a whole-house renovation alongside other work on your Harrow home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
