Cladding is a protective outer layer of boards or panels, such as timber, composite, fibre cement or uPVC, fixed to battens on the outside of a wall to change its appearance, shed rain and, where insulation is added, reduce heat loss.
For a homeowner in Harrow, planning cladding tends to begin with two questions: what will it cost, and how disruptive will it be? Our guide range is £6,500–£15,500 including VAT, and a typical job runs to 3 days to 3 weeks depending on area. Both numbers firm up once we have seen the property, measured up and agreed exactly what is included.

What should you budget for cladding in Harrow?
Here is how the guide price for cladding breaks down in Harrow. We start from national figures and adjust for London, which comes out about 30% above the national guide. The resulting range, VAT included, is £6,500–£15,500, and a survey, at no cost to you, firms it up.
| Type of job | What it usually involves | Guide in Harrow |
|---|---|---|
| Feature area or dormer | A gable, dormer, bay or small feature wall in uPVC, timber or composite. | £1,950–£6,500 |
| Extension or upper storey | About 40–60m² of timber, composite or fibre cement with membrane and battens. | £6,500–£15,500 |
| Whole house | Cladding most elevations of a house, often with added insulation. | £15,500–£39,000 |
Your price depends mostly on:
- Wall area to be clad and the height of the building
- Cladding material and board profile
- Insulation behind the cladding
- Scaffolding, access and distance from boundaries
What do you get?
- Breather membrane and treated battens fixed to the wall
- Insulation behind the cladding where agreed
- Cavity barriers and fire-stopping where regulations require
- Cladding boards fixed with suitable stainless or coated fixings
- Corner trims, window reveals and ventilated top and bottom edges
- Waste removal and a clean site on completion
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 cladding in Harrow at the survey stage.
Planning and building rules in Harrow
The notes below cover England, which is where Harrow sits. Rules change and every property is different, so we speak to the council before pricing your job.
In England, re-rendering or cladding a house is often allowed without planning permission, but stone, render, timber, plastic or tile cladding is not permitted development in conservation areas, and listed buildings need consent.
If you render or re-clad more than 25% of an external wall, Building Regulations usually require the wall’s insulation to be improved where that is practical, and building control should be notified.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Survey and measure
A free survey comes first. It gives us what we need to price cladding properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
After the survey we send a quote for cladding that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Getting ready
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
Build and hand over
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.

Frequently asked questions
Which postcodes in Harrow do you cover?
We cover HA1, HA2, HA3 and HA5, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Will timber cladding change colour?
Untreated timber cladding naturally weathers to a silver-grey over a year or two as sunlight breaks down the surface. The change can be uneven at first, especially under eaves where rain does not reach. If you want to keep the original colour, a UV-protective stain or oil is needed and must be renewed every few years. Pre-weathered and coated boards are also available.
Are there fire-safety rules for cladding?
Building regulations limit the fire-spread performance of cladding on walls close to a boundary and on taller buildings, which can rule out some timber or composite products in those positions. Cavity barriers behind the cladding also help stop fire spreading through the gap. Fibre cement is non-combustible. We check boundary distances and product data before recommending a material.
How much will cladding cost in Harrow?
As a guide, expect to pay £6,500–£15,500 including VAT for cladding in Harrow. That range is adjusted for London, which runs about 30% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
Can cladding improve insulation?
Cladding can improve insulation if insulation boards are fixed to the wall behind the battens, which reduces heat loss and can help with cold or damp internal walls. This adds thickness, so window reveals, sills and roof edges need careful detailing. Cladding alone, without insulation, adds very little warmth. We can price both options so you can compare.
