Highlights
"Very happy with the painting of whole house of walls and ceilings that Ernest has done. All work carried out very quickly and efficiently. Once one room was done all tided and furniture put back and cleaned. Very happy with the outcome."
"Ernest and his team were fantastic from start to finish. They converted our single loft bedroom to two rooms with new dormer and also knocked through the wall between our kitchen and dining room. Despite what could have been massive upheaval they worked around our family with minimal disruption and consistency. Ernest was always quick to answer any questions and reassured us throughout the process. The whole project was done quickly and to a high standard. The guys were the most friendly and professional we’ve ever had do work on the house. We wouldn’t hesitate in recommending them to anyone."
"Ernest carried out our open plan extension and kitchen work, and the quality was excellent. From start to finish, everything was handled in a professional manner. The work was completed on time, and the team kept the area clean and organised throughout. They paid close attention to detail and made sure everything was finished to a high standard. The team was friendly, helpful, and offered useful advice during the whole project. I would highly recommend John Builder Improvements to anyone looking for reliable and experienced professionals for an open plan extension or kitchen renovation."

"Architect" is a title protected by law - only people on the official Architects Register (held by ARB) may use it. Confirm they're on it before you commission a design.
Check the Architects RegisterSmart checks
Before you hire an architect
Only someone on the Architects Registration Board (ARB) register may legally call themselves an 'architect' in the UK — ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection).
Agree how they charge before any work starts — a percentage of the build cost, a fixed fee, or an hourly rate — and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later.
Confirm what they will actually handle versus what is excluded — the planning application, the building-control drawings, and whether they will administer the builder's contract on site — and get it, and a portfolio of similar projects, in writing.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
