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.
In Harpenden, as anywhere in Hertfordshire, the price of a whole-house renovation is driven mainly by size, materials and access. Across the East of England our guide sits at £47,000–£126,000 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

Building in Harpenden
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
New-town and garden-city homes often suit extensions, window replacement and roofline renewal, though some garden-city estates have their own design guidance. Victorian terraces commonly take loft rooms and side-return extensions.
None of this holds for every street in Harpenden, 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 Harpenden
Because Harpenden falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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.
The four stages
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a whole-house renovation so the price reflects your home.
Quote in writing
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Dates and permissions
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
The work itself
Our trades complete a whole-house renovation while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
Why homeowners choose us
Frequently asked questions
What contingency should I allow?
A contingency is money set aside for problems found once work starts, such as rotten joists, hidden damp or wiring that is worse than expected. For older houses, setting aside at least 10–15% of the build cost is sensible. We look for warning signs during the survey and price known issues upfront. If something unexpected is found, we explain it and price it before carrying on.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How much does it cost to renovate a whole house?
A full refurbishment of a typical 3-bed house costs £47,000–£126,000, 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.
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.
