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 offer a whole-house renovation across Surrey, and Sunbury-on-Thames is one of the places we cover, along with nearby Walton-on-Thames, West Molesey and Hampton. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in the South East it sits within £50,000–£134,000 including VAT.

Building in Sunbury-on-Thames
Surrey has many Victorian and Edwardian villas, interwar semis in the commuter towns near London, and Arts and Crafts houses with tile-hanging and tall chimneys. Bargate stone appears around Godalming, and large detached homes are common in Guildford, Woking, Weybridge and the Surrey Hills villages.
Mild and relatively dry, with clay soils in the north and Weald that can move in summer; mature trees near houses affect foundations.
None of this holds for every street in Sunbury-on-Thames, which is why we look at your actual house before pricing a whole-house renovation rather than assuming from its age alone.
Permissions for a whole-house renovation in Sunbury-on-Thames
Homes in Sunbury-on-Thames come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
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.
How does the job run?
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.
Price and scope agreed
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a whole-house renovation.
Plan and prepare
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
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
Why homeowners choose us
Common questions
What happens if you find damp or rot?
If we find damp or rot during a renovation, we stop that area, show you the problem and explain the likely cause, such as a leaking gutter, bridged damp-proof course or poor ventilation. We then give you a written price to fix the cause and repair the damage before carrying on. Treating the cause matters more than treating the symptom, so we focus on that first.
How much does it cost to renovate a whole house?
A full refurbishment of a typical 3-bed house costs £50,000–£134,000, covering rewiring, heating, plastering, a new kitchen and bathroom, flooring and decoration. A light refresh costs much less, while renovations with structural changes cost more. The biggest variables are the condition of the house and the kitchen and bathroom specification. We survey every room and give you a written price for the agreed scope.
Do you cover Walton-on-Thames, West Molesey and Hampton?
Yes. As well as Sunbury-on-Thames, we cover Walton-on-Thames, West Molesey and Hampton and the rest of Surrey. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
Can we live in the house while it is renovated?
Living in a house during a full renovation is possible but hard, especially while rewiring, plastering and the kitchen and bathroom are being done. Many people move out for the noisiest weeks or stay elsewhere for the whole project. If you stay, we can phase the work room by room and keep one bathroom and a basic kitchen working for as long as possible. We discuss this at the survey.
How much will a whole-house renovation cost in Sunbury-on-Thames?
