Extensions- 3 Jun 2025
From start to finish, Connor, Andrew and their team at Biggin Renovations Group Ltd provided exceptional service. We had a double storey side extension and garage connection to the house that included 2 new bedrooms and an en-suite completed. The team confirmed a 12 week timescale, and a week by week expectation of work to be completed, along with the payment plan which was all confirmed via contract. They stuck to their time schedules and completed on time. The price was within our budget. Along with Connor and Andrew, their team of subcontractors were very kind, helpful, polite and professional in the way they presented themselves. Very happy with the work that was completed, we will call them for our planned single storey extension in the near future. Highly recommend them.

Bathroom Fitting- 25 Feb 2022
This was the best experience I have ever had with a team of builders. Aldo and Leo were polite, organised and their workmanship is of a very high standard. They replaced the bathroom in our rental flat, and it looks really smart. They also refurbished the kitchen, replacing flooring and decorated the whole flat. We have just shown it to an estate agent as we are planning to sell it and they were very impressed. Aldo was very helpful in making suggestions of small changes that would save us money and delivered the project on time and right on budget. Would recommend them and will certainly use them again.
