Planning and building control requirements follow the rules for Northern Ireland, and we look into your property's position before a written quote is sent.

Housing across County Londonderry
Derry has Georgian and Victorian terraces around its walled city, alongside large post-war estates and newer developments. Coleraine, Limavady and Magherafelt mix older town centres with semis and estates, Portstewart has seaside villas, and rural areas have many detached homes and bungalows, often roughcast.
Terraces suit loft conversions and rear extensions, while rural bungalows commonly take extensions, loft rooms and driveways. Roughcast homes often need re-rendering, and coastal houses need roofline and window renewal.
The north coast faces Atlantic wind, rain and salt, and the Sperrins inland are colder and wetter.
Do you need permission in County Londonderry?
Because County Londonderry falls under Northern Ireland'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 Northern Ireland unless the building is listed.
The Building Regulations (Northern Ireland) apply to structural work, drainage and ventilation; electrical work should be tested and certified.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
We look at the job
First, someone visits your home in County Londonderry to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Written quote
After the survey we send a quote for a new bathroom that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
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
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Questions about a new bathroom in County Londonderry
Which postcodes in County Londonderry do you cover?
We cover BT48, BT52, BT49 and BT45, along with the rest of County Londonderry. 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.
Is a wet room right for my home?
A wet room is a fully waterproofed room with a shower area that drains through the floor, with no tray or step. It suits accessible bathrooms and modern designs, and makes cleaning easy. It needs a floor with enough depth for a gentle fall to the drain, and careful tanking of the whole room. Timber floors often need strengthening. We check suitability at the survey.
Will I have to go without a bathroom?
If it is your only bathroom, you will usually be without a shower or bath for most of the fitting time. We aim to keep the toilet working overnight wherever possible, refitting it temporarily at the end of each day during strip-out and first fix. If you have a second bathroom or downstairs toilet, the disruption is much easier. We plan the sequence with you before starting.
What ventilation does a bathroom need?
A bathroom needs mechanical ventilation, usually an extractor fan, to remove steam and help prevent condensation and mould. Building regulations set minimum extraction rates for new or refitted bathrooms. A fan linked to the light with an overrun timer, or one with a humidity sensor, works well. Ducting should vent outside by the shortest practical route. We include a suitable fan in every bathroom quote.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
