Late. Over budget. Impossible to reach.
Three words that shouldn't describe your renovation.
Six in-house trades. One fixed-price contract. One project manager from survey to sign-off. If the price changes, you agreed to it. If the date slips, you hear the day it slips.

Every trade your property needs. All under one roof.
No subcontractors, no finger-pointing, no 'that's not my department'. The same team that quoted the job runs it.
Decorating
Most painters skip the prep. That's why the finish fails six months later. We don't.
Read moreFlooring
A floor that creaks, gaps, or cups within two winters has a subfloor problem. We fix that first.
Read moreKitchen Fitting
A kitchen install is 20% carpentry and 80% project management. Most fitters only handle the 20%.
Read moreBathroom Fitting
Most bathrooms that fail weren't badly tiled. They were badly waterproofed underneath.

Stop fielding tenant maintenance calls at 11pm. One number handles everything.

No 'we'll be in touch'. A specific person, a specific calendar slot, a specific start date — and a price that doesn't change between the quote and the invoice.
A real site visit — not a quote by WhatsApp
A senior tradesperson visits the property, measures, photographs, and asks the questions a quote-by-message will always miss. This is how we catch the things that turn into surprises.
A line-by-line price that doesn't change
A written quote with labour and materials both itemised, inside three working days. Not an estimate. Not a range. The number you sign is the number on the invoice.
A real date — not "sometime next month"
Booked into our project calendar before anything is signed. The same project manager runs it from the first visit to the final snag walk-through.
We don't leave until the snag list is empty
We walk the property with you at the end. Anything that doesn't meet the spec gets fixed the same day. You get a written 12-month guarantee before we pack up.
The preparation, the communication, the guarantee — done properly.
Most renovation problems are predictable. Quoted low, charged high. Started late, finished later. Disappeared after the deposit. We've spent four years building systems that prevent exactly these — because the problems are always the same.
You deal with one person from the first visit to the final snag. They know the quote, they know the brief, they know the property. You don't get passed around to someone who has no idea what was agreed.
We agree both before anything is signed. If something slips, you hear about it the day it slips — not after you've already rearranged your life twice and the project is already a month late.
Every working day ends with tools off the floor, dust sheets down, materials stacked. We're working in your home, not a factory, and we treat it that way.
The guarantee is almost never used. But when it is, you get the same person who did the original work — not a stranger who doesn't know what was done or why.
£5m public liability. Gas Safe. Part P. NICEIC. TrustMark. Not for the website — because portfolio landlords ask for them before signing anything, and because they're legally required.
What clients say when we ask what surprised them most.
Most of our work is repeat business. These are people who used us once, then called us back for the next property.
“After three decorators who either skipped the prep, ran way over time, or hit us with a surprise invoice, we'd stopped trusting the process. Core Build Group quoted it properly, finished a day early, and the finish is still immaculate two years on. They're doing the next six.”
“The two other kitchen quotes didn't include the plumber or the electrician. Core Build Group's covered everything — one number, one invoice. The kitchen was functional by end of week one. I'd been dreading six weeks of chaos. It was two weeks of calm.”
“I oversee renovations professionally. The subfloor prep they did before laying a single board was more thorough than anything I'd seen from a residential contractor. 18 months on — no creak, no gap, no movement. They know what they're doing.”
