Free Consultation
We discuss your vision, budget, timeline, and priorities — no obligation, no pressure. We listen first so we can plan the right project for your property.
Site Survey & Assessment
We visit the property to inspect structure, services, and condition — identifying any issues, opportunities, and confirming the full scope of works before providing your quote.
Detailed Quote & Project Plan
A fixed-price, itemised quote with a clear project plan — scope, phasing, materials, and timeline confirmed before you commit to anything.
Planning & Approvals
We handle planning permission applications and building control notifications on your behalf — ensuring your renovation is fully compliant before works begin.
Structural Works
Wall removals, new openings, steel beam installations, and any structural alterations — carried out with structural engineer sign-off where required.
First Fix — Electrics, Plumbing & Heating
Rewiring, new consumer unit, updated plumbing, and new central heating installation — all first-fix works completed before walls are closed.
Insulation
Loft, internal wall, and underfloor insulation installed to PAS2035 — with walls open and floors lifted, this is the most cost-effective time to upgrade your home's thermal performance.
Plastering
Full plaster skim throughout — walls and ceilings prepared to a clean finish ready for decorating.
Second Fix — Kitchen, Bathroom, Flooring & Decorating
Kitchen and bathroom installation, tiling, floor laying, skirting boards, and full decoration — bringing the renovation to a finished, move-in ready standard.
Final Snagging & Handover
A comprehensive snagging inspection ensures everything is finished to specification — followed by building control sign-off, documentation, and formal handover.
We manage everything — one project manager, one team, no subcontractor chaos. You have a single point of contact from free consultation to the day we hand over the keys.
A full house renovation is the single best opportunity to upgrade your home's energy efficiency. When walls are open and floors are lifted, insulation and heating upgrades are far cheaper and less disruptive to install than as standalone works — and the long-term energy savings begin the moment you move back in.
Internal Wall Insulation (IWI)
For solid-wall properties where cavity wall insulation isn't possible, internal wall insulation dramatically reduces heat loss — and is significantly cheaper to install during a renovation when walls are already being opened and replastered.

Insulating under suspended timber floors cuts heat loss at ground level. When floors are already lifted during renovation works, fitting underfloor insulation adds minimal time and cost — but delivers years of improved efficiency and comfort.

Replacing old pipes, radiators, and a tired boiler with an efficient modern system while works are underway reduces installation costs considerably — and sets the property up for a heat pump upgrade in the future.
Smart Heating Controls
Integrated smart thermostats and zone controls are best wired in during first fix — giving you precise room-by-room temperature control from day one, reducing energy waste without any additional disruption later.
The Case for Doing It Now
Adding energy upgrades during a renovation saves you money on disruption (one set of trades, one set of mess, one period of upheaval) and starts saving you money on energy bills from the day you return. The same upgrades as standalone works later will cost significantly more and be far more disruptive.

Full house renovation costs vary significantly by property size, condition, and specification. As a guide: a 2-bedroom terrace typically costs £30,000–£50,000; a 3-bedroom semi £50,000–£80,000; a 4-bedroom detached £80,000–£150,000. These are indicative ranges for complete renovation packages — your exact cost is confirmed following a free site survey based on your specific property and requirements.
It depends on the scope of works. For a full gut renovation — where structural work, rewiring, and replastering affect the whole property — we generally recommend moving out for the duration. For less extensive renovations where only part of the property is affected, it may be possible to remain in place. We advise you clearly on this during the free consultation, based on your specific project scope.
A typical full house renovation takes 8–16 weeks depending on scope, property size, and structural complexity. We provide a detailed project timeline in your fixed-price quote — so you know the programme before any work begins. Larger properties or more complex projects may take longer; we confirm this at the survey stage.
