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.
Every house in Merthyr Tydfil is a little different, so we never price a whole-house renovation from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in Wales should budget £41,500–£110,000 including VAT, with work typically taking 8–24 weeks on site, depending on scope.

Homes in Mid Glamorgan
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
That mix of housing shapes how we approach a whole-house renovation in Merthyr Tydfil: the age and construction of your home affect the materials, the method and, in the end, the price.
Do you need permission in Merthyr Tydfil?
Because Merthyr Tydfil falls under Wales'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 improvements do not need planning permission in Wales unless the building is listed.
Building Regulations in Wales cover notifiable electrical work, drainage, ventilation and any structural change.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
Free site survey
A free survey comes first. It gives us what we need to price a whole-house renovation properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
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.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Common questions
How long does a full house renovation take?
A full renovation of a typical 3-bed house usually takes around 8–16 weeks on site, and longer if there are structural changes or extensive repairs. A light refresh may take only a few weeks. Material lead times for kitchens, windows and bathroom fittings also affect the programme. We give you a week-by-week plan with your quote and update it as the work progresses.
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
Do you cover Aberdare, Rhondda and Ebbw Vale?
Yes. As well as Merthyr Tydfil, we cover Aberdare, Rhondda and Ebbw Vale and the rest of Mid Glamorgan. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
Which postcodes in Merthyr Tydfil do you cover?
We cover CF47 and CF48, along with the rest of Mid Glamorgan. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
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.
